Overview

 

We are a clinical-stage biopharmaceutical company dedicated to developing next generation immunotherapies to transform the lives of patients with cancer. We are pioneering the use of tetravalent (2+2) bispecific antibodies to create a paradigm shift in cancer therapy. We have four second generation immuno-oncology (also referred to as "IO") therapeutics in the clinic, each directed against some of the most promising IO targets in drug development, including LAG-3 and CD137. Our proprietary antibody discovery platform is protected by an extensive intellectual property estate. We have over 500 granted patents and pending patent applications relating to our platform technology and product pipeline. We have attracted multiple partnerships with biotechnology and pharmaceutical companies targeting significant unmet needs across several disease areas, including oncology, immunology, and indications affecting the central nervous system (“CNS”) with over 20 programs being developed by our partners using our technology. Our goal is to offer patients better and more durable benefits than currently available immuno-oncology treatments by developing medicines that seek to block tumor immune evasion. Through our proprietary tetravalent, bispecific natural antibody ("mAb²™") format, our mission is to generate highly differentiated medicines with monoclonal antibody-like manufacturability, good safety and tolerability. With four distinct binding sites in a natural human antibody format, we believe our proprietary technology will overcome many of the challenges facing current immuno-oncology therapies, including other bispecific formats, due to the strong pharmacology enabled by tetravalent bispecific binding.

 

Our most advanced product candidate, FS118, is currently being evaluated in proof-of-concept Phase 2 trials in PD-1/PD-L1 acquired resistance head and neck cancer patients and in checkpoint inhibitor (“CPI”) naïve non-small cell lung cancer (“NSCLC”) and diffuse large B-cell lymphoma (“DLBCL”) patients. FS118 is a tetravalent mAb2 bispecific antibody targeting two receptors, PD-L1 and LAG-3, both of which are clinically validated targets in immuno-oncology. Phase 1 data from 43 heavily pre-treated patients with advanced cancer, who have failed PD-1/PD-L1 therapy, showed that administration of FS118 was well-tolerated with no dose limiting toxicities up to 20 mg/kg. In addition, a disease control rate (“DCR”), defined as either a complete response, partial response or stable disease, of 49% (19 out of 39) was observed in patients receiving dose levels of FS118 of 1mg/kg or greater. In acquired resistance patients, DCR was 55 % (17 out of 31 patients) in patients receiving 1 mg/kg or greater and long term (more than six months) disease control was observed in six of these patients. We expect to provide an update from the proof-of-concept Phase 2 trial in PD-1/PD-L1 acquired resistance head and neck cancer patients in mid-2022. Data reported during the first half of 2021, from a randomized Phase 3 trial conducted by another company in patients with previously untreated, locally advanced or metastatic melanoma provides clinical validation for the combination of LAG-3 and PD-1 inhibition. This clinical benefit in targeting PD-1 and LAG-3 gives us reason to believe that FS118 has potential to benefit patients not only with acquired resistance, but also in preventing resistance in patients receiving PD-1 monotherapy for the first time. With respect to the latter, we initiated a clinical trial of FS118 in CPI-naïve patients in biomarker enriched NSCLC and DLBCL populations in late 2021.

 

Our second product candidate, FS222, aims to improve outcomes particularly in patients with tumors that express low levels of PD-L1 and is a mAb2 bispecific antibody that is designed to target both the costimulatory CD137 receptor and the inhibitory PD-L1 ligand, which are co-expressed in many tumor types. The Phase 1 clinical trial evaluating FS222 in patients with advanced cancers is ongoing. We believe there is a strong rationale to combine FS222 with other anti-cancer agents, and this can be done within the Phase 1 trial. The accelerated dose titration was completed in the second half of 2021, and identification of optimal patient groups, dose and schedule is on-going. We expect to provide an update on the progress of the Phase 1 trial in mid-2022 and report safety, biomarker, and preliminary efficacy data in the second half of 2022.

 

Our third product candidate, FS120, aims to improve checkpoint inhibitor and chemotherapy outcomes and is a mAb2 bispecific antibody that is designed to bind to and stimulate OX40 and CD137, two proteins found on the surface of T cells that both function to enhance T cell activity. We are developing FS120 alone and in combination with PD-1 therapy for the treatment of tumors where PD-1 inhibitors are approved, and which have been associated with co-expression of OX40 and CD137 in the tumor microenvironment. The Phase 1 clinical trial in patients with advanced cancers is ongoing and we completed the accelerated dose titration phase during the second half of 2021. We are continuing further dose escalation to determine an optimal dosing regimen to initiate a combination of FS120 and the PD-1 inhibitor, pembrolizumab, in the

second half of 2022. Pembrolizumab will be supplied under a clinical trial collaboration and supply agreement with Merck & Co.

 

SB 11285, which we acquired pursuant to a business combination with Spring Bank Pharmaceuticals, Inc. (“Spring Bank”), is a next generation cyclic dinucleotide STimulator of INterferon Gene (“STING”) agonist designed to improve checkpoint inhibition outcomes as an immunotherapeutic compound for the treatment of selected cancers. SB 11285 appeared to be well tolerated both alone and in combination with atezolizumab across all dose levels tested to-date, including five dose levels as monotherapy and three dose levels as a combination. Initial analysis showed that pharmacokinetics (“PK”) were in-line with the predicted profile for rapid cellular uptake, a characteristic of second generation STING agonists. We are continuing with further dose-escalation and pursuing strategic business development opportunities for SB 11285 in parallel. We expect to report an update on this trial in the second half of 2022.

 

The following table sets forth our product candidates and their current development stages. Our portfolio includes further preclinical and clinical programs that are being developed by our partners as described below under “Collaborations and License Agreements”.

We leverage our proprietary mAb2 technology to build our portfolio of wholly owned immuno-oncology mAb2 product candidates and have generated a panel of early stage Fcab, Fc with antigen binding, building blocks against a range of targets with the potential to go beyond immuno-oncology. These Fcab building blocks have been used to generate not only bispecific antibodies, but also trispecific antibodies and fusion proteins. We have over 500 granted patents and pending applications relating to our mAb2 technology and our product pipeline. We believe we have a leading position in mAb2 bispecific antibody development, and third parties are prohibited from utilizing our mAb2 technology without obtaining a license from us.

 

We currently have collaborative partnerships with Ares Trading S.A., an affiliate of Merck KGaA, Darmstadt, Germany, Denali Therapeutics Inc. and Janssen Biotech, Inc. ("Janssen"), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, which enable us to further validate our bispecific platform. In addition, we have a partnership with AstraZeneca AB ("AstraZeneca") to develop STING inhibitors. F-star's collaborations have generated payments of over $250 million since inception. We believe that these partnerships will provide both continued validation and ongoing revenue as we continue to advance our proprietary pipeline and platform technology. Though our collaborative partnerships we have the potential for a further $2.2 billion in revenue.

We are led by a team of highly experienced executives, clinicians, scientists and advisors with notable expertise in antibody research, immuno-oncology, antibody manufacturing and clinical development. Our team has spent over a decade developing our proprietary mAb2technology into a robust drug discovery platform. Our team has collectively worked on the development of 25 marketed products and has worked at companies including AstraZeneca, Bristol-Myers Squibb Company ("BMS"), Celgene Corporation, Domantis, Eli Lilly and Company ("Eli Lilly"), GlaxoSmithKlein ("GSK"), Immunocore and Pfizer, Inc ("Pfizer").

 

Strategy

 

We are dedicated to developing next generation immunotherapies to transform the lives of patients with cancer by generating highly differentiated, first and/or best-in-class product candidates. The key elements of our strategy include:

Rapidly accelerating the clinical development of our three novel mAb2 product candidates and novel cyclic dinucleotide, SB 11285, to treat a range of advanced cancers. We believe our mAb2product candidates represent potentially best-in-class immuno-oncology therapies that may address a variety of patients with cancer inadequately treated with existing therapies. We believe FS118, which is being evaluated in proof-of-concept Phase 2 trials in PD-1/PD-L1 acquired resistance head and neck cancer patients and in CPI-naïve NSCLC and DLBCL patients, has the potential to provide significant clinical benefit through its dual-checkpoint inhibitor targets (LAG-3 and PD-L1). In addition to FS118, we are currently evaluating FS222, FS120 and SB 11285 for safety, tolerability and efficacy in Phase 1 clinical trials in patients with advanced cancers. All of our product candidates have the potential to address multiple immune evasion pathways that limit the effect of current immuno-oncology therapies.
Initially focusing our development strategy on tumors where checkpoint inhibitors are currently utilized but are poor long-term treatment options, and then subsequently broadening to other tumor types. Our early-stage clinical trials include, or will include, a broad range of tumor types to evaluate safety, tolerability and dosing, as well as early signals of efficacy. Following these early-stage clinical trials, we intend to employ a patient selection strategy, using biomarkers to focus further development on targeted patient subsets. These subsets are expected to include patients with high cancer target co-expression and/or resistance to current checkpoint therapies. We believe our mAb2 bispecific antibodies and SB 11285 may also ultimately deliver therapeutic benefit in a broader range of tumors, expanding beyond the initial indications we may pursue. We believe our development strategy best serves the patient, can be efficiently pursued by our organization, and has the potential to lead to a rapid development strategy and regulatory pathway to market. For example, we have identified several tumor types which have a strong fit with the potential FS118 mechanism of action, including appropriate target expression, that may be candidates for accelerated approval pathways.
Leveraging the transformational potential of our modular antibody technology platform to create a leading immuno-oncology pipeline of differentiated clinical assets capable of improving patient outcomes. We believe our proprietary mAb2 bispecific antibodies have a number of potential advantages, compared to other modalities, resulting from their novel tetravalent and natural human antibody formats, which may result in improved efficacy, minimized toxicity and simplified manufacturability. We believe our technology has the potential to be matched with any disease target in a modular “plug-and-play” approach to further expand our innovative pipeline of mAb2 product candidates. We also believe these benefits may provide multiple opportunities to consistently generate clinical candidates that could potentially address the needs of patients who are without adequate therapeutic options.
Leveraging and continuing to build our extensive intellectual property portfolio in order to protect our dominant position in mAb2 bispecific antibodies and our STING agonist program. We have built an extensive patent portfolio around our mAb2 technology and associated mAb2 product pipeline. In addition, we have STING pathway-related filings, including those of a patent family relating to the composition of matter of the STING agonist SB 11285. This patent estate relates to our mAb2 bispecific format and STING agonist program and aims to provide us with robust intellectual property exclusivity and prohibit use of our technology by third parties. We intend to continue to seek additional patent protection as we develop additional novel mAb2 product candidates.

The Immuno-oncology Challenge and our mAb2 Technology

 

Cancer Treatment Overview

 

The incidence of cancer is increasing due to the aging of the world population, as well as an increasing prevalence in individuals with known risk factors. Based on GLOBOCAN 2020 estimates, approximately 19.2 million new cancer cases were diagnosed, and 9.9 million cancer deaths occurred in 2020 worldwide. Cancer treatment has traditionally included chemotherapy, radiation, hormone therapy, surgery or a combination of these approaches. While these approaches can be effective in treating certain types of cancers, many can also cause toxicities that may have life-threatening consequences, lower quality of life or untimely termination of treatment. Furthermore, we believe the traditional therapeutic approaches have reached their efficacy plateau with limited room to prolong the patient’s life expectancy. More recently, cancer research has leveraged antibody approaches to target the emerging field of immuno-oncology, which aims to enhance natural anti-tumor immune responses by, for example, overcoming mechanisms that cancer cells have developed to evade the immune system. Initially, antibody approaches were developed for treatment in second- or third-line settings but, recently, have become more common as the standard of care, first-line treatment for a variety of tumor types, including NSCLC, melanoma, renal cell carcinoma, liver cancers, gastric cancers and head and neck cancers, amongst others. We believe this has created a significant treatment gap and new unmet need for the majority of patients whose disease becomes resistant to those antibodies in addition to the substantial number of patients who do not benefit from these first generation antibodies at all.

 

F-star Solution to the Unmet Medical Need in Immuno-oncology

 

In 2020, combined sales of current immuno-oncology therapies were approximately $28.7 billion worldwide. Despite the commercial success of these products, only approximately 20% of patients realize a long-lasting benefit from these treatments, leaving the majority, unserved patient population without effective treatment options. Our mAb2 bispecific antibodies have the potential to overcome the limitations associated with current antibody therapies in immuno-oncology. They not only bind to two cancer targets at the same time, but the efficient receptor crosslinking and clustering of tumor and immune cells can also increase overall potency and induce a differentiated biological response. Our current mAb2 product candidates are directed against targets that have already demonstrated some level of clinical activity in clinical trials using single traditional antibodies. The target pairings for our mAb2 product candidates are selected on the basis of co-expression in tumors of defined patient populations with an unmet medical need, some of which have orphan status and would be candidates for accelerated approval. Our mAb2 product candidates are progressed only if they demonstrated potential advantages in preclinical studies, such as safety and/or potency, beyond what would be achieved with the combination of two traditional antibodies and that in some instances differentiate from other bispecific antibody formats.

 

We believe our mAb2 bispecific antibodies may address the limitations of current immuno-oncology therapies through the following advantageous characteristics that differentiate our mAb2 product candidates:

Novel Tetravalent Format. We engineer our mAb2 bispecific antibodies to simultaneously bind two different targets, with two binding sites for each target. The ability to bind in this way is known as tetravalency. This unique tetravalent format is designed to enable our mAb2 bispecific antibodies to achieve more efficient crosslinking, clustering or conditionality than other bispecific antibodies, and therefore have the potential to elicit improved biological responses and enable our mAb2 bispecific antibodies to overcome tumor evasion pathways. These three key characteristics are described further below:
Crosslinking. Crosslinking is the act of bringing either two target-bearing cells, or two targets on the same cell, into close proximity. The dual binding sites for each target, within our bispecific antibodies, enables durable and strong target crosslinking through the ability to engage with target-bearing cells simultaneously, for example, engaging both tumor cells and immune cells.
Clustering. Many cellular receptors can only be optimally activated when many of those receptors are brought into close physical proximity on the cell surface, referred to as “clustering”. Since our mAb2 bispecific antibodies have F-star’s distinct binding sites, they can potentially induce more potent clustering than non-tetravalent bispecific antibody formats.
Conditionality. Conditionality occurs when immune activation is dependent on the bispecific antibody binding both targets simultaneously, often in the tumor microenvironment. We are able to leverage the prospectively engineered tetravalent format of our mAb2 bispecific antibodies so that targets are only activated when they are simultaneously bound.

4


 

Natural Human Antibody Format. Our mAb2 bispecific antibodies are designed to conserve the natural human antibody format, with greater than 95% identity, allowing us to leverage the following advantages:
Minimal systemic toxicity. Since our mAb2 bispecific antibodies use a natural human antibody format, without synthetic linkers and domains, there is lower potential for systemic toxicity than traditional and bispecific antibodies.
Low immunogenicity risk. The natural human antibody format of our mAb2bispecific antibodies and the low number of modifications we engineer into our mAb2 bispecific antibodies is designed to help mitigate immunogenicity risk, or the risk that the immune system recognizes the mAb2bispecific antibody as foreign, potentially resulting in lower exposure and toxicity.
Ease of manufacturability. We are able to produce our mAb2 bispecific antibodies through established manufacturing processes readily and at large scale with typical industry time and cost standards and without potentially complicating additions, such as domain assembly or other modifications.

 

We believe the novel tetravalent and natural human antibody formats of our mAb2 bispecific antibodies have the potential to focus immune activation to enhance efficacy and reduce systemic toxicities.

Our mAb2 Potential Advantages over Other Antibodies and Bispecific Antibodies

FS118 – Our LAG-3 and PD-L1 mAb2 Bispecific Antibody

 

img72950008_2.jpg 

Our most advanced product candidate, FS118, aims to rescue or prevent checkpoint inhibitor treatment failures and is a mAb2bispecific antibody targeting two receptors, PD-L1 and LAG-3, both of which are clinically validated pivotal targets in immuno-oncology. We are currently conducting proof-of-concept Phase 2 trials for FS118 in PD-1/PD-L1 acquired resistance head and neck cancer patients and checkpoint inhibitor naïve NSCLC and DLBCL patients. Phase 1 data demonstrated that FS118 is well tolerated with a disease control rate of 49% (19 out of 39) patients treated at 1 mg/kg and above in a heavily pretreated population and supports the testing of FS118 in cancers with acquired resistance to prior PD-1/PD-L1 inhibitors

 

Inhibitory Roles of LAG-3 and PD-L1 in Immuno-oncology

 

PD-1 is a checkpoint inhibitor that is present on the surface of activated T cells and has a role in downregulating the immune system to help prevent an attack on healthy tissue. However, this inhibitory mechanism can also prevent the immune system from killing cancer cells. PD-L1, the ligand for PD-1, is expressed by a broad range of both tissues and immune cells. A wide range of tumors, including solid tumors, can upregulate PD-L1 in response to pro-inflammatory cytokines, such as interferon gamma. Engagement of PD-L1 with PD-1 on activated tumor infiltrating lymphocytes (“TILs”), can deliver inhibitory signals that protect the tumor from immune destruction.

 

LAG-3 is also a checkpoint inhibitor expressed on immune cells, including activated T cells. LAG-3 binds to a group of cell surface proteins known as major histocompatibility complex (“MHC”), class II molecules that are present on antigen presenting cells. MHC proteins are responsible for presenting foreign antigens to the immune system, after which the T cells are activated to attack and clear the foreign entity. When MHC class II molecules bind to LAG-3, this T cell activation is suppressed, which, under normal conditions, helps to prevent over activation of the immune system. In tumors, LAG-3 becomes overexpressed on TILs, thereby suppressing the T cell activation needed for an anti-tumor immune response. Accordingly, LAG-3 expression in TILs is generally associated with poor prognosis. A role for LAG-3 shedding in resistance to PD-1 blockade has been highlighted in a recent preclinical study showing that mice that are unable to shed LAG-3 from the surface of T cells are resistant to PD-1 therapy. A high level of LAG-3 and low levels of a disintegrin and metalloproteinase (“ADAM”)-10, a metalloproteinase regulating LAG-3 shedding, on T cells from the blood of patients with head and neck cancer was also associated with a poor prognosis.

 

Data reported in the first half of 2021, from a randomized phase 3 trial conducted by another company in patients with previously untreated, locally advanced or metastatic melanoma provided clinical validation for the combination of LAG-3 and PD-1 inhibition. This clinical benefit in targeting PD-1 and LAG-3 gives us reason to believe that FS118 has potential to benefit patients not only with acquired resistance, but also in preventing resistance in patients receiving PD-1 monotherapy for the first time.

 

Potential Clinical Applications of a LAG-3/PD-L1 Bispecific Antibody

 

Therapeutic antibodies that reverse the immunosuppression of checkpoint inhibitors, thereby “releasing the brake” to allow the T cell to attack the tumor cell, have been clinically successful. Currently, several PD-1/PD-L1 antibodies are in development or have been approved by the FDA and other regulatory agencies in a variety of tumor types, including lung cancers, melanoma, renal cancers, bladder cancers, gastro-intestinal cancers, liver, head and neck and breast and cervical cancers. This cancer population represented over 10 million cases worldwide in 2020. Although long-lasting responses to PD-1/PD-L1 have been observed, the cancer ultimately becomes resistant, leaving a large, unserved patient population without effective treatment options, despite a portion of these patients expressing PD-1/PD-L1.

Emerging data suggest that LAG-3 upregulation may be a mechanism of resistance to PD-1 or PD-L1 therapy. A key observation is that therapeutic inhibition of the PD-1/PD-L1 checkpoint pathway leads to increased expression of LAG-3, which, in turn, may prevent responses to PD-1/PD-L1 therapy. Both LAG-3 and PD-1 become overexpressed on TILs in multiple preclinical tumor models and the combination of LAG-3 and PD-1 antibodies have demonstrated improvement of the anti-tumor response in murine models compared to blocking either one alone. The potential therapeutic benefit of the combination of traditional antibodies and bispecific antibodies targeting PD-1 and LAG-3 has been investigated in several clinical trials, and preliminary clinical results have indicated activity in PD-1/PD-L1 treatment naïve and resistant tumors.

 

Based on results generated using a combination of two traditional antibodies targeting PD-1 and LAG-3, and the observation that an increase in LAG-3 expression may contribute to resistance to PD-1 checkpoint therapy, we believe that a bispecific antibody that targets both PD-L1 and LAG-3 simultaneously, such as FS118, has broad potential as an immuno-oncology therapeutic. Simultaneous targeting of LAG-3 and PD-L1 with a bispecific antibody not only releases the brakes of two immunosuppressive pathways, but it may also have advantages over a combination of traditional antibodies by focusing these effects at PD-L1 positive sites in the tumor or by crosslinking between immune cells in the tumor microenvironment. Recently, LAG-3 shedding was found to correlate with responsiveness to PD-1 therapy in murine tumors and in the clinic high levels of LAG-3 and low levels of ADAM-10 correlated with a poor outcome of PD-1 treatment. Therefore, increased shedding of LAG-3 from the surface of the T cell, due to tetravalent bispecific-binding to LAG-3 and PD-L1, may result in lower LAG-3 levels in the tumor and potentially prevents one of the mechanisms of acquired resistance to PD-1/PD-L1 therapies.

 

Resistance to PD-1/PD-L1 regimens can come in two main forms. “Primary resistance” is where the cancer shows no sensitivity to treatment and continues to grow. “Acquired resistance” to PD-1/PD-L1 regimens, sometimes referred to as secondary resistance, is where there is initial sustained (greater than or equal to three months) clinical benefit (defined as a complete response, partial response, or stable disease) from therapy but the cancer then starts to grow again while the patient is still being treated. Our analysis of preliminary clinical data from the first-in-human trial of FS118 indicates that FS118 may have greater clinical activity in patients with acquired resistance compared to primary resistance. We also believe that FS118 has the potential to have clinical activity in checkpoint inhibitor (“CPI”) naïve cancer patients who have not previously been exposed to PD-1/PD-L1 therapy. Our trial in CPI naïve NSCLC and DLBCL patients aims to address the hypothesis that FS118 may have clinical activity in this population and may act to prevent the emergence of LAG-3 driven checkpoint resistance in these patients.

 

Tumor types with immuno-suppression or T cell exhaustion may co-express LAG-3 and PD-L1 and could benefit from treatment with our dual checkpoint inhibitor product candidate, FS118. Examples of such tumors include head and neck, NSCLC, soft-tissue sarcoma, mesothelioma, ovarian, gastric cancer, anaplastic thyroid cancer, small cell lung cancer and hematological cancers such as DLBCL and Hodgkin’s Lymphoma. Globally, this cancer population represents over 4.5 million new diagnoses annually. Our focus will be on patients with cancers whose tumors co-express LAG-3 and PD-L1 and who have developed acquired resistance to PD-1/PD-L1 therapy or who have not yet received it.

 

Squamous cell carcinoma of the head and neck, otherwise known as head and neck cancer, includes cancers of the mouth (oral cavity, oral cancers, tongue) and throat (oropharynx and tonsils, nasopharynx and hypopharynx), as well as rarer cancers of the nasal cavity, sinuses, salivary glands and the middle ear. According to GLOBOCAN, in 2020 approximately 900,000 new head and neck cancer were estimated to have been diagnosed worldwide. Treatment of patients with advanced head and neck cancer consists of PD-1 therapy alone or in combination with chemotherapy in the first-line, in the metastatic setting. Approximately one-third of these patients develop Acquired Resistance to PD-1 therapy and, therefore, we plan to develop FS118 as a sequential treatment for these patients, either alone or in combination with standard of care therapies.

 

NSCLC is one of the most common cancers and is the number one cause of cancer death in men, representing 85% of all lung cancers, with approximately 1.85 million patients diagnosed globally in 2020. Checkpoint blockade has led to a paradigm shift in the treatment of NSCLC with significant improvements in long-term survival over recent years. However, a significant number of patients suffer from disease progression and are inherently resistant to PD-1 therapy or acquire resistance upon treatment. Understanding how to avoid or prevent resistance could enable the development of improved clinical therapies. We plan to develop FS118 as a treatment for NSCLC and to demonstrate that FS118 can improve patient outcome.

DLBCL is the most common type of non-Hodgkin lymphoma (“NHL”) with an estimated 77,240 new cases in the US in 2020. Approximately 60% of DLBCL cases are cured with regimens such as rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin and prednisone combination ("R-CHOP"), but many patients relapse following treatment, or are refractory to initial treatment. While developments in the fields of adoptive cell therapy have significantly improved the outcomes of patients, there is still a need for new therapies to treat patients with refractory disease. We plan to develop FS118 to provide patients with chemotherapy-free regimens, either alone or in combination with standard of care therapies in order to improve the outcome for patients with limited treatment options and whose tumors express LAG-3.

 

Our Solution to Overcoming and Preventing PD-1/PD-L1 Resistance: FS118

 

FS118 is a mAb2 bispecific antibody that can simultaneously bind to LAG-3 through its Fcab domain and PD-L1 via its Fv domain. FS118 has demonstrated the potential to provide clinical benefit through multiple mechanisms based on its tetravalency. These include: (1) blocking the PD-1/PD-L1 immunosuppressive pathway, (2) blocking the LAG-3/MHC class II molecules interactions and (3) PD-L1 dependent shedding of LAG-3 via a process dependent upon cleavage by metalloproteases.

Mechanism of Action of FS118

 

img72950008_3.jpg 

 

Our preclinical data demonstrated that FS118 is a potent inhibitor of PD-L1 and LAG-3 and has the potential to be more effective than a combination of PD-L1 and LAG-3 traditional antibodies. Moreover, these preclinical mice studies showed that administration of the mAb2bispecific antibody led to a downregulation of LAG-3 expression levels on T cells within the tumor, with an increase in serum soluble LAG-3, which we believe is due to receptor clustering, and is indicative of the strong pharmacology enabled by tetravalent bispecific binding, this LAG-3 downregulation was not observed in mice treated with PD-L1 or LAG-3 mAbs alone or in combination. Furthermore, our human in vitro assays have shown that FS118 can mediate PD-L1 dependent LAG-3 shedding via a process that is dependent upon proteases that are known to cleave LAG-3. We believe these mechanisms are important for potent disease control.

Phase 1 Clinical Trial

 

We have conducted a first-in-human Phase 1, open-label, dose-escalation clinical trial of FS118 in patients with advanced malignancies that have progressed on or after PD-1/PD-L1 checkpoint therapy for whom either no effective standard therapy is available or standard therapy has failed. The tumor types enrolled in this trial include sarcomas, lung cancers, mesothelioma, bladder cancers, ovarian cancers, prostate cancers, melanoma, mesothelioma, head and neck cancers, cervical cancers and thyroid cancers. Patients were heavily pretreated, including surgical procedures, chemotherapy or radiation therapy, and with a median of three regimens (range 1-11) of therapy in the advanced/metastatic disease setting. In addition, patients were required to have received prior treatment with a PD-1/PD-L1 containing regimen for a minimum of 12 weeks and subsequently shown disease progression. This patient population derives infrequent benefits from any further PD-1 therapy, and disease worsening may occur within eight weeks without an effective therapy.

 

Under the protocol, as depicted below, 43 patients received FS118 administered intravenously once weekly in three weekly cycles until disease progression. The initial cohorts were enrolled sequentially in single-patient dose escalation cohorts. Because no dose limiting toxicities were observed, further dose escalation up to 20 mg/kg proceeded in a 3+3 design associated with cohort extension to obtain more PK/PD data. The primary endpoints of this trial are safety, tolerability and pharmacokinetics. Secondary endpoints include disease control, as measured by RECIST 1.1 and iRECIST.

FS118 Phase 1 Clinical Trial Design

 

img72950008_4.jpg 

 

A total of 43 patients were enrolled in this trial at dose levels up to 20 mg/kg and data from this trial demonstrated that weekly administration of FS118 was well-tolerated and did not result in dose- or treatment-limiting toxicities and a maximum tolerated dose was not reached. No safety signals unexpected for the drug class of immune-checkpoint inhibitors were identified. The majority (95%) of treatment-emergent adverse events (“TEAE”), considered by the scientific review committee to be treatment-related were mild to moderate in severity (grade 1 and 2). FS118-related grade 3 toxicities (liver enzyme increases) were observed in two patients (4.7%). No treatment related adverse events above grade 3 were reported and no deaths were attributed to FS118 treatment. A recommended dose for Phase 2 trials (“RP2D”) was determined to be 10 mg/kg weekly.

 

A disease control rate (“DCR”) of 49% of (19 out of 39) patients was observed in patients receiving dose levels of 1 mg/kg or above. In six of these patients, long term disease control (greater than six months) was observed, and it was noted that all of these patients had acquired resistance to their previous PD-1 or PD-L1 therapy. In acquired resistance patients the DCR was 55 % of (17 out of 31) patients receiving 1 mg/kg or above.

Overall, any observed immunogenicity, as defined by the presence of confirmed positive anti-drug antibodies ("ADAs"), was typically transient in nature (i.e. did not persist for longer than 3 consecutive cycles). Immunogenicity was observed in 49% of (21 of 43) patients treated with FS118. No effect on exposure was observed. FS118 exhibited dose-linear pharmacokinetics with a terminal half-life of four days, as determined by pharmacokinetic data fit to a two-compartment model. Pharmacodynamic exposure was maintained across the dosing interval, as measured by a dose-dependent increase in soluble LAG-3, with a maximal level of sLAG-3 being reached at 10mg/kg. Analysis of immune cell subsets in the periphery revealed an increase in the percentage of circulating lymphocytes in patients who demonstrated disease stabilization, compared to those with progressive disease. Furthermore, a significant increase in the percentage of proliferating CD4+, CD8+ and NK cells was observed following FS118 treatment.

Clinical Development Strategy

 

The FS118 first-in-human clinical trial data support further clinical investigations for monotherapy FS118 in cancers with acquired resistance. Initial clinical trials will take place in the second/third line metastatic setting. In order to identify patients who may gain more benefit from FS118 therapy, we plan to investigate a number of biomarkers. Rational combinations with other anti-cancer therapies are also being considered for patients who are pre-treated with, or naïve to, PD-1/PD-L1 therapy.

 

We initiated a focused monotherapy proof-of-concept Phase 2 trial in selected head and neck cancers with acquired resistance in 2021. Squamous Cell Carcinoma of Head and Neck was chosen for the proof-of-concept trial based on both the existence of the targeted population of acquired resistance following the approval of a PD-1 inhibitor and the expression of both PD-L1 and LAG-3 in this patient set. If the trial meets its primary objective of efficacy in LAG-3+/PD-L1+ patients, we expect that additional clinical studies in head and neck cancer will follow, assessing FS118 alone or in combination with other tumor targeting antibodies or chemotherapeutic agents. A Phase 3 registration clinical trial would subsequently be conducted.

 

In late 2021, to address the hypothesis that FS118 may prevent the emergence of resistance to checkpoint inhibitors, we initiated a Phase 2 basket trial in patients NSCLC and DLBCL who had not previously received checkpoint inhibitors. If the trial meets its primary objective of efficacy, we expect that additional trials in these tumor types will follow, with the potential to assess FS118 as a monotherapy or in combination with other agents. Subsequently, a registrational trial would be conducted.

 

Other tumor types of interest that co-express PD-L1 and LAG-3, such as small cell lung cancer, ovarian cancer, mesothelioma, Hodgkin’s lymphoma and anaplastic thyroid tumors will be investigated in a “basket” or “platform” clinical trial. This is designed to facilitate multiple clinical efficacy signals with FS118 therapy in these tumor types and has the potential to apply biomarker patient selection strategies to enrich for efficacy and provides opportunity for accelerated approval.

 

If these trials are successful, we intend to seek marketing approval from the FDA, the EMA and other comparable regulatory bodies.

FS222 – Our CD137 and PD-L1 mAb2 Bispecific Antibody

 

img72950008_7.jpg 

FS222 aims to improve outcomes of patients with tumors that express low levels of PD-L1 by tumor proportion score (“TPS”) and is a mAb2 bispecific antibody that is designed to target both the costimulatory CD137 receptor and the inhibitory PD-L1 ligand, which are co-expressed in many tumor types including, for example, NSCLC, ovarian cancer and gastrointestinal cancers such as colorectal cancer. The Phase 1 clinical trial in patients with advanced cancers for FS222 is ongoing. The accelerated dose titration of FS222 in the Phase 1 trial (Part A) was completed successfully in the second half 2021, and identification of optimal patient groups, dose and schedule is on-going. We believe there is a strong rationale to combine FS222 with other anti-cancer agents, including targeted therapy and chemotherapy, and this can be done within the Phase 1 trial.

 

Potential Clinical Applications of a CD137/PD-L1 Bispecific Antibody

 

A CD137 and PD-L1 bispecific antibody has the potential to increase the efficacy compared to the combination of two traditional antibodies. Both targets are present within the tumor microenvironment. Blocking the PD-L1 pathway acts to “release the brake” thereby reducing immunosuppression, while stimulating the CD137 pathway acts to “hit the gas” and amplify immune cell activation. CD137-driven T cell activation results in interferon gamma cytokine release. This cytokine release causes increases in PD-L1 expression on tumor and immune cells. We believe that this upregulation of PD-L1 could be a resistance mechanism of traditional CD137 antibody therapy that limits its activity in the tumor microenvironment.

 

We intend to develop FS222 in selected advanced cancers. Tumor type such as NSCLC, soft tissue sarcoma, triple negative breast cancer, squamous cell carcinoma of the head and neck, ovarian cancer, colorectal cancer, and including biomarker subsets of these tumor types, are likely to have tumor-resident T cells and NK cells expressing CD137, as well as cells that express PD-L1. These represent tumor types that individually and collectively have a spectrum of PD-L1 expression from high to low. These cancer types are diagnosed in over 5 million patients globally every year and represent attractive indications for FS222. We plan to focus on defined clinical and biomarker segments of these cancers. For example, there is need for chemotherapy-free regimens in first-line PD-L1 low NSCLC. We believe there is a broad opportunity for FS222, either alone or in combination with other anti-cancer therapies, in treating these patient populations.

 

Our Solution: FS222

 

FS222 is a mAb2 bispecific antibody that binds to CD137 through its Fcab domain and PD-L1 via the Fv domain. FS222 simultaneously “releases the brake” on immune control of cancer by blocking the PD-1/PD-L1 pathway and “hits the gas” on immune cell activation by activating the CD137 pathway. FS222 has the potential to provide clinical benefit through multiple mechanisms based on its tetravalency. These include: (1) blocking the PD-1/PD-L1 immunosuppressive pathway and (2) conditionally clustering and crosslinking CD137 receptors, resulting in activation of CD137 in a PD-L1-dependent manner. We believe this dual mechanism of action would amplify the anti-tumor activity of FS222. Our preclinical data shows that FS222 has the potential to be more effective than a combination of traditional PD-L1 and CD137 antibodies, as well as applicability in PD-L1 low tumors, a significant area of unmet medical need.

12


 

Mechanism of Action of FS222

 

img72950008_8.jpg 

 

Our preclinical data demonstrated that FS222 is a potent stimulator of CD137, only when cross linked by PD-L1. FS222 has been designed with specific mutations to make its activity independent of binding to Fc gamma receptors. PD-L1 is frequently expressed at high levels on cells within cancer tissue compared to non-cancer tissue. Co-expression of CD137 and PD-L1 has been observed in human tumors including NSCLC and our preclinical studies have shown that CD137 and PD-L1 are co-expressed at higher levels on TILs than in peripheral blood. Therefore, we believe this will make FS222 immune activation conditional within cancer tissue, limit potential systemic toxicities and lead to safety benefits.

13


 

 

Superior anti-tumor activity observed compared to a combination of traditional antibodies

 

In an established preclinical mouse tumor model (MC38), treatment with a mouse mAb2 bispecific antibody equivalent of FS222 (mouse CD137/PD-L1 mAb2) was observed to lead to long-term survival and complete tumor elimination in all treated mice, an effect that was observed to be unmatched by two traditional antibodies in combination. We believe this effect was observed because of FS222’s ability to deliver the dual anti-cancer mechanisms.

 

 

img72950008_9.jpg 

 

FS222 was observed to be well-tolerated in preclinical studies

 

In an IND/CTA-enabling toxicology study conducted in non-human primates, FS222 was observed to be well-tolerated at doses up to the maximum administered dose of 30 mg/kg. No adverse observations, including no acute increases in serum cytokines levels were reported. This was consistent with our results from cytokine release assays performed using human blood. The non-human primate study also showed dose-dependent increases in proliferating CD4+ (helper), CD8+ (killer) T cells and NK cells, consistent with our findings in murine pharmacology studies using the CD137/PD-L1 mAb2 surrogate.

 

Clinical Plans

 

The Phase 1 open-label, dose-escalation clinical trial of FS222 in patients with advanced cancers is ongoing. This trial is divided into Part A, accelerated dose titration ("ADT") and 3+3 escalation, and Part B, tumor-specific efficacy expansion cohorts. The ADT component of Part A was completed in the second half of 2021. The initial safety and proof-of-concept efficacy studies in selected tumor types will be conducted within the Phase 1 protocol. While we attempt to establish the preliminary safety and optimal dosing regimen for FS222, we will simultaneously investigate preliminary efficacy signals with FS222 therapy in a small number of tumor types of interest, potentially including colorectal, NSCLC, triple negative breast cancer, squamous cell carcinoma of the head and neck, and ovarian cancer. We will also potentially explore biomarker subsets of these tumor types. These data will form the basis for the selection of specific tumor types in which to assess the clinical activity of FS222 in a larger group of patients in the Phase 1 trial (Part B). This approach could potentially support expedited regulatory approval and/or the initiation of Phase 3 registrational trials.

FS120 – Our OX40 and CD137 mAb2 Bispecific Antibody

 

img72950008_10.jpg 

FS120 aims to improve checkpoint inhibitor and chemotherapy outcomes and is a mAb2 bispecific antibody that is designed to bind to and stimulate OX40 and CD137, two proteins found on the surface of T cells that both function to enhance T cell activity. We are developing FS120 alone and in combination with PD-1/PD-L1 therapy for the treatment of tumors where PD-1/PD-L1 products are approved and which have been associated with co-expression of OX40 and CD137 in the tumor microenvironment, such as NSCLC and bladder cancer. The Phase 1 clinical trial in patients with advanced cancers is ongoing and the accelerate dose titration phase was completed in the second half of 2021. Further dose escalation is ongoing.

 

Stimulatory Roles of OX40 and CD137 in Immuno-oncology

 

The biological basis for primary and acquired resistance to current checkpoint therapies has been widely explored, resulting in the identification of many contributory factors. Key among these factors are the number of TILs and the number of mutations in the tumor cells, which is known as the tumor mutational burden (“TMB”). Tumors with low levels of TILs, referred to as “cold” tumors, are less responsive or non-responsive to current therapies.

 

One approach to increase the number and level of activation of TILs is by broad stimulation of the immune system via costimulatory regulators. Preclinical studies showed that the anti-tumor efficacy of therapeutic tumor targeting antibodies can be augmented by the addition of antibodies targeting costimulatory molecules, such as CD137 and OX40.

 

When TILs first become activated, they upregulate OX40 and CD137 which are members of the tumor necrosis factor receptor superfamily. Further activation can be achieved by stimulation of OX40 and CD137. OX40 stimulation promotes T cell proliferation and survival and decreases the activity of immuno-suppressive T cells to further amplify the immune activation. Moreover, it preserves cellular memory for a more durable response and facilitates migration to other tumor sites. CD137 is expressed on multiple cell types including T cells and natural killer (“NK") cells. CD137 stimulation on T cells helps to mount an effective immune response by enhancing T cell proliferation and survival. Both the OX40 and CD137 activation pathway requires receptor clustering of the respective molecules on cells that triggers a signaling cascade resulting in enhanced immune response and thereby, tumor cell killing.

 

Potential Clinical Applications of an OX40/CD137 Bispecific Antibody

 

OX40 and CD137 agonist antibodies can “hit the gas” (immune stimulation) and have been shown to be effective immunotherapeutic agents across preclinical cancer models. Traditional OX40 antibodies have been extensively studied in the clinic as monotherapies. In addition, OX40 antibodies have been studied in combination with PD-1/PD-L1 and CTLA-4 antibodies and chemotherapy. Other programs are exploring a triple combination approach with PD-L1, CD137 and OX40 antibodies.

 

Despite encouraging preclinical data, in clinical trials, monotherapy with traditional CD137 antibodies has not restored immune control of cancer in the majority of patients. In the case of the two most advanced traditional CD137 antibodies in clinical trials, doses tested have either demonstrated early efficacy but have been limited by severe liver toxicity or have been well-tolerated but have not demonstrated anti-cancer efficacy even at the highest doses tested. Both of these traditional CD137 antibodies are being tested in combination with PD-1/PD-L1 antibodies and other agents to potentially improve efficacy.

 

15


 

OX40 activation predominantly stimulates CD4+ T cells, called helper T cells, whereas CD137 stimulates CD8+ T cells, called killer T cells. We believe a bispecific antibody that “hits the gas” simultaneously through OX40 and CD137, such as FS120, will be able to concentrate these different immune cell subsets in the tumor, increasing activity of both helper and killer T cells. In addition, we believe this targeted stimulation of the immune system will increase the number of activated TILs in the tumors. Both mechanisms lead to stronger anti-tumor activity and increased therapeutic benefit as compared to traditional antibodies. Using a bispecific dual agonist for broad stimulation could also be combined with checkpoint inhibitors, including PD-1 and PD-L1.

 

We believe that our preclinical data support FS120 being developed in combination with PD-1/PD-L1 therapy or other agents such as chemotherapy. This approach may broaden the application of PD-1/PD-L1 therapy to tumor types or sub-populations that respond poorly to PD-1/PD-L1 therapy because they are likely to have TILs expressing both CD137 and OX40. Conversely, a PD-1/PD-L1 and FS120 combination may deepen clinical responses and prolong clinical benefit in patients who already gain benefit from PD-1/PD-L1 therapy. In order to select tumor types of interest, we analyzed gene expression data from solid tumors and found highly correlated expression levels of both OX40 and CD137 in several cancers where PD-1/PD-L1 therapy is approved including, but not limited to, bladder, head and neck, small and NSCLC.

 

NSCLC is one of the most common cancers, with approximately 1.85 million patients diagnosed globally in 2020. PD-1 and PD-L1 mAbs are approved as a monotherapy or in combination with chemotherapy. Patients with high levels of PD-L1 may receive PD-1/PD-L1 monotherapy while the combination with chemotherapy is a common option for patients with PD-L1 low cancers. There remains a significant need to identify chemotherapy free treatment regimens for these patients. FS120 potentially offers an opportunity of a chemotherapy-free treatment in combination with PD-1/PD-L1 therapy for patients with PD-L1 low tumors.

 

Bladder cancer was diagnosed in over 500,000 patients globally in 2020. PD-1 therapy is approved for use in the first line setting in patients who are not eligible for standard chemotherapy and who have high levels of PD-L1. Head and neck cancer affects over 900,000 patients world-wide every year. Therapy with PD-1 regimens is approved as a treatment in the first line setting. However, clinical outcomes remain suboptimal across PD-L1 levels and we believe there is an opportunity to bolster PD-1 clinical activity through combining with FS120 in first-line treatment. To address the need for treatment across these populations, we plan to explore pembrolizumab in combination with FS120 in these clinical settings.

 

Our Solution: FS120

 

FS120 is a mAb2 bispecific antibody that binds to OX40 through its Fcab domain, and CD137 via the Fv domain. FS120 is a dual costimulatory antibody or agonist that “hits the gas” on immune activation by activating both CD137 and OX40. We believe the tetravalent binding of FS120 differentiates it from current therapeutic approaches being developed in the clinic, because FS120 is designed to lead to enhanced clustering and potent and conditional stimulation between T cells (trans) and potentially on the same cell (cis).

16


 

Mechanism of Action of FS120

img72950008_11.jpg 

 

Our preclinical studies have shown superior anti-tumor activity of a mouse OX40/CD137 mAb2 compared to a combination of two traditional antibodies. Based on the results, we believe FS120 may deliver clinical benefit through mechanisms arising from dual stimulation. These include: (1) activation of TILs in tumors to help overcome checkpoint inhibitory signals, which we believe will improve the response rates to PD-1/PD-L1 inhibitors and (2) increasing the number and persistence of CD4+ (helper) and CD8+ (killer) T cells and destabilizing T regulatory cells, which has the potential to reduce the risk of relapse for patients treated with the standard of care.

 

Traditional CD137 antibodies have Fc domains that lead to crosslinking using Fc gamma receptors that are widely expressed in the body, which are believed to result in off-tumor activation of immune cells and subsequent hepato-toxicities. Accordingly, we designed FS120 with specific mutations that alter the binding of the Fc domain to Fc gamma receptors to prevent the killing of the immune cells by antibody dependent cellular cytotoxicity (“ADCC”) and to make FS120 activity independent of Fc gamma receptors, which we believe is important for efficacy and safety benefits. Both OX40 and CD137 are found highly expressed in TILs versus blood. Therefore, we believe this will make FS120 immune activation conditional within cancer tissue, limit potential systemic toxicities and lead to safety benefits.

 

Enhanced anti-tumor response to PD-1 blockade observed

 

We observed a significant reduction in tumor growth in an established preclinical mouse tumor model (CT26) in a treatment with a mouse mAb2 bispecific antibody equivalent of FS120, referred to as the mouse OX40/CD137 mAb2. When the mouse OX40/CD137 mAb2 was used in combination with a PD-1 antibody, we observed increased long-term survival and enhanced effector cell cytotoxicity compared to what was observed with the monotherapy of either PD-1 or the mouse OX40/CD137 mAb2.

 

17


 

img72950008_12.jpg 

 

FS120 was observed to be well-tolerated in preclinical studies

In an IND-enabling toxicology study conducted in non-human primates, FS120 was observed to be well-tolerated at doses up to the maximum administered dose of 30 mg/kg. No adverse observations, including no acute increases in serum cytokines levels were reported. This was consistent with our results from cytokine release assays performed using human blood. The non-human primate study also showed dose-dependent increases in proliferating CD4+ (helper), CD8+ (killer) T cells and NK cells, consistent with our findings in murine pharmacology studies using the OX40/CD137 mAb2 surrogate.

 

18


 

Clinical Plans

 

The Phase 1 open-label, dose-escalation clinical trial of FS120 in patients with advanced cancers is ongoing. The accelerated dose titration phase was completed in the second half of 2021. Further dose escalation is ongoing. Furthermore, we intend to explore FS120 in combination with PD-1 therapy focusing on selected tumor types. In the future, FS120 may also be explored in combination with other agents such as chemotherapy. The initial safety and proof-of-concept efficacy studies in selected tumor types will be conducted within the Phase 1 protocol. This approach could potentially support expedited regulatory approval and/or the initiation of Phase 3 registrational trials.

 

SB 11285 – Our STING Agonist

 

img72950008_13.jpg 

SB 11285 is a next generation cyclic dinucleotide STING agonist designed to improve checkpoint inhibition outcomes as an immunotherapeutic compound for the treatment of selected cancers. We are conducting an open-label, dose-escalation Phase 1 clinical trial with SB 11285 as an IV administered monotherapy, and in combination with a PD-L1 antibody, in patients with advanced solid tumors. We are continuing dose-escalation and in pursuing partnering opportunities for SB 11285 in parallel.

 

Potential Clinical Application of STING Agonist

 

The induction of interferons and interferon-stimulated genes in tumor cells and within the tumor microenvironment has been shown to modulate the host-immune response and induce apoptosis of tumor cells. Activation of the STING pathway can result in the induction of cellular interferons including interferon-b and other cytokines while promoting a strong anti-tumor response through the induction of innate and adaptive immune responses. Therapeutically targeting the STING pathway could turn an immunologically “cold” tumor into a “hot” one, making it more likely to respond to other forms of immunotherapy, such as immune checkpoint inhibitors.

 

The cyclic GMP-AMP synthase ("cGAS")–STING pathway is involved in the innate immune response against the tumor. Upon detection of cytosolic tumor-derived DNA, cGAS generates cyclic dinucleotides that bind STING, leading to the release of Type-I interferon and proinflammatory cytokines, ultimately promoting T cell priming and recruitment. STING also regulates anticancer immunity in a Type I interferon-independent manner by inducing cell death and facilitating the release of cancer cell antigens. Multiple STING agonists are being investigated in clinical trials, but many exhibit poor metabolic stability and were delivered intratumorally. A STING agonist that can be administered IV has the potential to target advanced metastatic tumors such as melanoma and head and neck carcinomas.

 

Squamous cell carcinoma of the head and neck, otherwise known as head and neck cancer, includes cancers of the mouth (oral cavity, oral cancers, tongue) and throat (oropharynx and tonsils, nasopharynx and hypopharynx), as well as rarer cancers of the nasal cavity, sinuses, salivary glands and the middle ear. According to GLOBOCAN, in 2020 approximately 900,000 new head and neck cancer cases were estimated to have been diagnosed worldwide.

 

The approval of the check point inhibitor pembrolizumab as a monotherapy or in combination with chemotherapy represents an opportunity for the STING agonist to improve upon the efficacy of a PD-1/PD-L1 inhibitors and offer to the patients a chemotherapy free option.

Our Solution: STING Agonist

 

We are developing our STING agonist product candidate, SB 11285, as a next-generation immunotherapeutic synthetic cyclic dinucleotide for the treatment of selected cancers. In preclinical studies in multiple tumor-derived cell lines, SB 11285 induced the release of cytokines consistent with engagement of the STING target, as well as cell death and apoptosis. Based on the preclinical studies performed to date, SB 11285 has demonstrated efficacy in multiple rodent tumor models when administered intravenously or intratumorally. We believe that SB 11285 may be administered clinically by multiple routes of administration, enabling SB 11285 to target a variety of tumors at various anatomic sites. Furthermore, SB 11285 has the potential to be used in combination with other therapeutic modalities to enhance efficacy. Following the administration of SB 11285 in a preclinical tumor model, there was upregulation of the PD-1 molecule, which we believe underscores the potential utility of its approach to employ the activity of a PD-1/PD-L1 checkpoint inhibitor.

 

Ongoing Phase 1 Clinical Trial and Clinical Development Strategy

 

SB 11285 is currently being evaluated as an IV-administered monotherapy in a Phase 1 multicenter, dose escalation clinical trial in patients with advanced solid tumors. Part 1a of this trial is a dose-escalation study with IV SB 11285 monotherapy and part 1b is a dose escalation of SB 11285 combined with a fixed and therapeutic dose of aPD-L1 antibody. Roche’s PD-L1 checkpoint inhibitor atezolizumab (Tecentriq®) is being used. This trial is designed to determine a recommended Phase 2 dose for both the monotherapy and combination with atezolizumab.

 

The objectives of the Phase 1 clinical trial include determining a safe and pharmacodynamically active dose of IV-administered SB 11285 and preliminary assessment of antitumor activity. The Phase 1 dose escalation study was designed to evaluate ascending doses of SB 11285 with respect to dose-limiting toxicities, maximum tolerated dose, and to determine a recommended Phase 2 dose as well as the pharmacokinetic/pharmacodynamic profile as monotherapy and in combination with atezolizumab. Following the completion of the part 1a/1b portion of the trial, part 2 of the trial is designed to explore the antitumor activity of SB 11285 in combination with atezolizumab in pre-specified tumor types such as head and neck cancer and melanoma.

 

SB 11285 appeared to be well tolerated both alone and in combination with atezolizumab across all dose levels tested to-date, including five dose levels as monotherapy and three dose levels as a combination. Initial analysis showed that PK were in-line with the predicted profile for rapid cellular uptake, a characteristic of second generation STING agonists. We are continuing with further dose-escalation and expects to provide a further update in the second half of 2022 and pursuing strategic business development opportunities for SB 11285 in parallel.

 

Collaborations and License Agreements

We have entered several collaborations and license agreements with an aim to discover and develop novel drug candidates across a variety of clinical indications.

 

2016 License and Collaboration Agreement with Denali Therapeutics Inc.

 

In August 2016, we and certain of our subsidiaries entered into a license and collaboration agreement (the “Denali License and Collaboration Agreement”), with Denali Therapeutics Inc. (“Denali”). The goal of the collaboration was the development of certain constant Fc domains of an antibody with non-native antigen binding activity (“Fcabs”), to enhance delivery of therapeutics across the blood brain barrier into the brain. The collaboration was designed to leverage our modular antibody technology and Denali’s expertise in the development of therapies for neurodegenerative diseases. In connection with the entry into the collaboration agreement, Denali also purchased from the F-star Gamma shareholders an option, which we refer to as the buy-out-option, to acquire all of the outstanding shares of F-star Gamma pursuant to a pre-negotiated share purchase agreement.

 

On May 30, 2018, Denali exercised the buy-out option and entered into a Share Purchase Agreement (the “Purchase Agreement”), with the shareholders of F-star Gamma and Shareholder Representative Services LLC, pursuant to which Denali acquired all of the outstanding shares of F-star Gamma (the “Acquisition”).

 

20


 

As a result of the Acquisition, F-star Gamma has become a wholly owned subsidiary of Denali and Denali changed the entity’s name to Denali BBB Holding Limited. In addition, Denali became a direct licensee of certain of our intellectual property (by way of Denali’s assumption of F-star Gamma’s license agreement with us (the “F-star Gamma License”)). Denali made initial exercise payments in the aggregate, of $18.0 million, less the net liabilities of F-star Gamma, which were approximately $0.2 million. Of this total, $4.0 million was payable to us. In June 2019, Denali made a payment of $1.5 million to us upon achieving a Good Manufacturing Practice ("GMP") Manufacturing milestone. Under the terms of the agreement the Company is entitled to receive contingent payments that relate to certain defined preclinical, clinical, regulatory, and commercial milestones with a maximum value of $49.5 million.

 

Under the terms of the Denali License and Collaboration Agreement, Denali had the right to nominate up to three Fcab targets (“Accepted Fcab Targets”), within the first three years of the date of the Denali License and Collaboration Agreement. Upon entering into the Denali License and Collaboration Agreement, Denali had selected transferrin receptor (“TfR”), as the first Accepted Fcab Target and in May 2018, Denali exercised its right to nominate two additional Fcab targets and identified a second Accepted Fcab Target.

 

Under the Denali License and Collaboration Agreement, Denali was responsible for payment of certain research costs incurred by us in conducting activities under each agreed development plan, for up to 24 months. The last of the agreed development plans concluded in February 2021, with us having no ongoing obligation to conduct research activities under the Denali License and Collaboration Agreement.

 

Under the terms of the Denali License and Collaboration Agreement, we are prohibited from developing, commercializing and manufacturing any antibody or other molecule that incorporates any Fcab directed to an Accepted Fcab Target, or any such Fcab as a standalone product, and from authorizing any third party to take any such action.

 

2018 Agreement with Iontas Limited

 

In March 2018, we entered into an agreement (the “Iontas Agreement”), with Iontas Limited (“Iontas”), pursuant to which we acquired all Iontas’ right, title and interest in and to certain anti-PD-L1 human antibodies. Additionally, Iontas granted us a worldwide, exclusive license under any know-how or related intellectual property rights to exploit any products containing such antibodies. In connection with the Iontas Agreement, an upfront fee of £0.2 million ($0.3 million) was paid by us to Iontas.

 

Pursuant to the Iontas Agreement, we are obligated to pay an annual fee of £0.1 million ($0.1 million) and up to £0.4 million ($0.5 million) in the aggregate for certain specified preclinical milestones on a per product basis. We are obligated to pay Iontas up to £13.0 million ($17.6 million) in the aggregate upon the achievement of certain development and regulatory milestones and up to £12.8 million ($17.2 million) in the aggregate upon the achievement of certain commercial milestones, in each case on a per product basis.

 

Unless earlier terminated, the term of the Iontas Agreement will continue in perpetuity. We may terminate the Iontas Agreement upon specified prior written notice. Additionally, either party may terminate the Iontas Agreement in the event of an uncured material breach under the Iontas Agreement by the other party or for certain bankruptcy or insolvency events involving the other party.

2019 License and Collaboration Agreement with Ares Trading S.A., an affiliate of Merck KGaA, Darmstadt, Germany (as amended, July 2020)

 

On May 13, 2019, we entered into a license and collaboration agreement (the “Ares Agreement”), with Ares, pursuant to which we granted Ares the option to enter into a worldwide, exclusive license to certain of our patents and know-how to develop, manufacture and commercialize two separate mAb2 antibody products that each contain a specific Fcab and a Fab target pair (each a licensed product), in the field of the treatment and prevention of diseases in humans.

 

Under the Ares Agreement, we received reimbursement of our internal and external development costs for each preclinical program. Under the Ares Agreement we conducted certain mutually agreed upon preclinical development activities and delivered data packages to Ares. Following receipt of each data package, Ares had the option to continue with the program and if Ares elected to continue with the program, Ares would be solely responsible for the continued development, manufacture and commercialization of the applicable licensed products. Ares exercised its option in relation to one of the preclinical programs (the “First Program”) on May 13, 2019 and exercised its option in relation to the second preclinical program (the “Second Program”) in July 2020.

 

In July 2020, the Ares Agreement was amended such that we granted Ares a time-limited option to enter into a worldwide, exclusive license to develop, manufacture and commercialize two additional mAb2 products (the “Third Program” and the “Fourth Program”) in the field of the treatment and prevention of diseases in humans. With respect to the Third Program and Fourth Program, we are not required to deliver data packages to Ares. In March 2021 Ares exercised its option for the Third Program and in January 2022, exercised its option for the Fourth Program. As a result, Ares will be solely responsible for the continued development, manufacture and commercialization of the applicable licensed products.

 

During the term of the Ares Agreement, we are subject to certain non-compete obligations.

 

Pursuant to the Ares Agreement, Ares paid €10 million ($11.2 million) in connection with the exercise of the option for the First Program, €7.5 million ($8.5 million) in connection with the exercise of the option for the Second Program and €2.25 million ($2.52 million) for both the third and fourth programs. Additionally, Ares is obligated to pay us up to €408.5 million ($462.6 million) in the aggregate for the programs upon the achievement of certain development and regulatory milestones and up to €252 ($285.4 million) in the aggregate upon the achievement of certain commercial milestones. We are eligible to receive a low single digit royalty on net sales of licensed products. The royalties payable to us under the Ares agreement may be reduced under certain circumstances. Our right to receive royalties under the Ares Agreement expires, on a licensed product-by-licensed product and country-by-country basis, on the latest of: (i) the expiration, invalidation or abandonment date of the last valid licensed patent claim that relates to such licensed product in such country, (ii) the expiration of regulatory exclusivity for such licensed product in such country and (iii) the twelfth anniversary of the first commercial sale of such licensed product in such country.

 

In connection with the Ares Agreement, we also granted Ares the right to negotiate a royalty agreement in the event of commercialization of FS118, and we reserved the right to receive a license to Ares’ FS118 manufacturing technology and a transfer of certain materials, provided such technology is not subject to a legal restriction. If this royalty agreement is entered into, we may be obligated to pay Ares a low single digit royalty on net sales of FS118 products, subject to certain reductions.

Unless earlier terminated, the term of the Ares Agreement will expire on a program-by-program basis on the date on which Ares has no further milestone or royalty obligations with respect to such program. We may terminate the Ares Agreement if Ares or any sublicensee challenges any patent licensed to it under the Ares Agreement. Ares may terminate the Ares Agreement on a program-by-program basis for convenience at any time effective upon expiration of certain specified notice periods. Either us or Ares may terminate the Ares Agreement in the event of an uncured material breach by the other party or for certain bankruptcy or insolvency events involving the other party; provided, however that, in the event of our uncured material breach, under certain circumstances Ares may elect not to terminate the Ares Agreement and instead, as its sole remedy, to reduce future milestone and royalty payments by an agreed upon amount.

 

2021 License Agreement with AstraZeneca AB

 

On July 7, 2021, we entered into an exclusive licensing agreement (the “AstraZeneca Agreement”) with AstraZeneca, under which we granted AstraZeneca global rights to research, develop and commercialize STING inhibitor compounds.

 

23


 

Under the terms of the AstraZeneca Agreement, we granted AstraZeneca exclusive access to F-star’s novel preclinical STING inhibitors. AstraZeneca will be responsible for all future research, development and commercialization of the STING inhibitor compounds, and we will retain rights to all STING agonists, currently in clinical development for patients with cancer.

 

We have received or are eligible to receive upfront and near-term payments under the AstraZeneca Agreement of up to $12 million. In addition, We will be eligible for development and sales milestone payments of over $300 million, as well as single-digit percentage royalty payments. Payments received by us are subject to a contingent value rights agreement, under which a percentage will be payable to stockholders of F-star that were previously stockholders of Spring Bank prior to the business combination between F-star and Spring Bank.

 

2021 License and Collaboration Agreement with Janssen Biotech, Inc.

 

On October 19, 2021, we entered into a license and collaboration agreement (the “Janssen Agreement”) with Janssen Biotech, Inc., one of the Janssen Pharmaceutical Companies of Johnson & Johnson.

 

Under the Janssen Agreement, Janssen received a worldwide exclusive license to research, develop and the option to commercialize up to five novel bispecific antibodies directed to Janssen therapeutic targets using our proprietary Fcab and mAb2 platforms. Janssen is responsible for all research, development, and commercialization activities.

 

We have received or are entitled to receive upfront fees of $17.5 million, and near-term fees and potential further milestones of up to $1.35 billion. We are also eligible to receive potential tiered mid-single digit royalties on annual net sales of any products that receive regulatory approval and are commercialized using the licensed technology.

 

Manufacturing

 

We do not currently own or operate manufacturing facilities for production of clinical or commercial quantities of any of our drug candidates or their components. We currently generate batches of our mAb2 bispecific antibody candidates in our laboratories for initial preclinical studies using standardized procedures. We rely on and expect to continue to rely on third-party contract manufacturing organizations (“CMOs”), to manufacture clinical materials and any future commercial materials for our product candidates. We require our CMOs to produce bulk drug substance and finished drug product in accordance with current Good Manufacturing Practices and all other applicable laws and regulations. We maintain agreements with our CMOs that include confidentiality and intellectual property provisions to protect our proprietary rights related to our product candidates. We believe that both the standard IgG platform processes used for mAb2 manufacturing and chemical synthesis used for SB 11285 manufacturing can be transferred to a number of other CMOs for the production of clinical and commercial supplies of our product candidates in the ordinary course of business.

 

Competition

 

The biotechnology and pharmaceutical industries, in developing novel and proprietary therapies for the treatment of cancer, are characterized by rapidly advancing technologies and innovation, intense competition and a strong emphasis on intellectual property. We believe that our differentiated technology, dominant intellectual property position, significant development experience and scientific knowledge provide us with competitive advantages. However, we face potential competition from many different sources, including large biotechnology and pharmaceutical companies, academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection, and establish collaborative arrangements for the research, development, manufacturing, and commercialization of oncology therapies. We anticipate that we will face intense and increasing competition from the constantly evolving therapeutic landscape, as new drugs and therapies enter the market and advanced technologies become available. Any product candidates that we successfully develop and commercialize will compete with new oncology therapies that may become available in the future.

 

We compete in the segments of the biotechnology, pharmaceutical and other related markets that develop immuno-oncology therapies. There are many other companies that have commercialized and/or are developing immuno-oncology therapies for cancer including large biotechnology and pharmaceutical companies, such as AstraZeneca, BMS, EMD Serono, Genentech, a member of the Roche Group, Eli Lilly, MSD, Novartis, Pfizer, and Sanofi. Several companies, not limited to those above, are attempting to combine immuno-oncology antibody therapies to modulate two cancer pathways simultaneously. Others have

24


 

developed bispecific antibodies that maximize the co-targeting effect of a combination of single-target traditional antibodies into a single molecule.

 

With respect to our mAb2 bispecific antibody pipeline, we are aware of several competitors using other technology methods to create bispecific antibodies to treat a variety of cancer types, including, but not limited to Genmab A/S, Inhibrx, MacroGenics, Merus, Pieris Pharmaceuticals, Hoffmann-LaRoche, Shattuck Labs, and Xencor, Inc.

With respect to our lead mAb2 product candidate, FS118, we are aware of other competing molecules targeting LAG-3 and PD-1/PD-L1 receptors. Companies pursuing a bispecific molecule directed against LAG-3 and PD-1/PD-L1 in different phases of clinical development include but are not limited to Epimab, Hoffmann-La Roche, I-mab/ABLBio, Innovent, and MacroGenics. We are also aware of other companies pursuing a combination of two traditional antibodies in different phases of clinical development, with the first one targeting PD-1/PD-L1, and the second one targeting LAG-3, which include but are not limited to: BMS, C.H. Boehringer Sohn AG & Co. KG, Nanjing Leads Biolabs/Beigene, and MSD, Novartis, and Regeneron.

 

With respect to our second mAb2 product candidate, FS222, we are aware of other companies pursuing bispecific antibodies targeting PD-L1 and CD137 in clinical development, which include but are not limited to: ABL Bio, Antegene, Biotheus, Genmab/BioNTech SE, Inhibrx/Elpiscience, Merus, Numab Therapeutics AG/CStone Pharmaceuticals, Pieris/Servier, and Qilu Pharmaceutical Co. We are also aware of other companies that are pursuing a combination of two traditional antibodies in clinical development, with the first one targeting PD-1/PD-L1, and the second one targeting CD137, which include but are not limited to: Adagene, BMS, Eucure Biopharma, Hoffmann-La Roche, Lyvgen Biopharma (Suzhou)/MSD and, Pfizer.

 

With respect to our third mAb2 product candidate, FS120, we are aware of other companies pursuing bispecific antibodies targeting OX40 and CD137, which include but are not limited to Aptevo Therapeutics. We are also aware that Pfizer has ongoing clinical studies evaluating a combination of CD137 plus OX40 traditional antibodies.

 

With respect to our fourth product candidate, SB 11285, we are aware of other companies pursuing a second generation, intravenously administered STING agonist, in clinical development which include but are not limited to: GSK, Millennium Therapeutics/ Takeda and Stingthera, Inc. Additionally, several other companies are developing a first generation and/or an intratumorally administered STING agonist in the clinic.

 

Many of the companies against which we are competing or against which we may compete in the future, either alone or with their strategic collaborators, have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals, and marketing approved drugs than we do. Mergers and acquisitions in the biotechnology, pharmaceutical and diagnostic industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through unforeseen technological innovations, or collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and enrolling patients for our clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

 

We could see a reduction or elimination of our commercial opportunity if our competitors develop and commercialize products that are safer, more efficacious, have fewer or less severe side effects, are easier to administer, or are less expensive than any products that we may develop. Our competitors also may obtain FDA, EMA or other foreign regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market.

 

Intellectual Property

 

We strive to protect and enhance the proprietary technology, inventions and improvements that are commercially important to the development of our business, including seeking, maintaining and defending patent rights, whether developed internally or licensed from third parties. We also rely on trade secrets relating to our proprietary modular antibody technology platform and on know-how, continuing technological innovation and in-licensing opportunities to develop, strengthen and maintain our proprietary position in the immuno-oncology field and other fields that are or may be important for the development of our business. We additionally expect to rely on regulatory protection afforded through orphan drug designations, data exclusivity, market exclusivity and patent term extensions where available.

 

25


 

Our commercial success may depend in part on our ability to obtain and maintain patent and other proprietary protection for commercially important technology, inventions and know-how related to our business; defend and enforce our patents; preserve the confidentiality of our trade secrets; and operate without infringing the valid enforceable patents and proprietary rights of third parties. Our ability to stop third parties from making, using, selling, offering to sell or importing our products may depend on the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities. With respect to both licensed and company-owned intellectual property, we cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will be commercially useful in protecting our commercial products and methods of manufacturing the same.

 

Individual patents extend for varying periods depending on the date of filing of the patent application or the date of patent issuance and the legal term of patents in the countries in which they are obtained. Generally, patents issued for regularly filed applications in the United States are granted a term of 20 years from the earliest effective non-provisional filing date. In addition, in certain instances, a patent term can be extended to recapture a portion of the U.S. Patent and Trademark Office delay in issuing the patent as well as a portion of the term effectively lost as a result of the FDA regulatory review period. However, as to the FDA component, the restoration period cannot be longer than five years and the total patent term including the restoration period must not exceed 14 years following FDA approval. Where a U.S. patent is subject to a terminal disclaimer, the term of the patent may alternatively be shorter than 20 years.

 

We have developed or in-licensed numerous patents and patent applications and possess substantial know-how and trade secrets relating to the development and commercialization of our mAb2 product candidates and the underlying modular antibody technology platform and have also acquired a patent family relating to our STING agonist product candidate, SB 11285. To date, our patent estate includes over 500 granted patents and pending patent applications generally directed to, for example, compositions and methods related to our Fcabs, our modular antibody technology platform, our lead mAb2 product development candidates, our STING agonist SB 11285 and other STING agonist compounds, and other products, proprietary technologies and processes.

Government Regulation and Product Approval

 

In the United States, the Food and Drug Administration ("FDA") regulates therapeutics like our mAb2 product candidates as biological products, or biologics, and therapeutics like SB 11285 as drugs under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act and related regulations. Biologics and drugs are also subject to other federal, state, local and foreign statutes and regulations. Failure to comply with the applicable U.S. regulatory requirements at any time during the product development process, approval process or after approval may subject an applicant to significant fines and penalties, including administrative or judicial actions. These actions could include, for example, the suspension or termination of clinical trials by the FDA or an Institutional Review Board (“IRB”), the FDA’s refusal to approve pending applications or supplements, revocation of a biologics license, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, import detention, injunctions, civil penalties or criminal prosecution. Any such penalty or enforcement action could have a material adverse effect on us.

 

The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon the clinical development, manufacture and marketing of biologics and drugs. These agencies and other federal, state, local and foreign entities regulate, among other things, research and development activities and the testing, manufacture, quality control, effectiveness, safety, purity, potency, labeling, packaging, storage, distribution, record keeping and reporting, approval, import and export, advertising and promotion and post-market surveillance of biologics and drugs.

 

The FDA’s and comparable regulatory agencies’ policies may change, and additional government regulations may be enacted that could prevent or delay regulatory approval of any future product candidates or approval of product or manufacturing changes, new disease indications, or label changes. We cannot predict the likelihood, nature or extent of adverse governmental regulation that might arise from future legislative or administrative action, either in the United States or abroad.

 

Product Development

 

In the United States, the FDA regulates human drugs and biologics under the Federal Food, Drug, and Cosmetic Act, or the FDCA, and in the case of biologics, also under the Public Health Service Act, or the PHSA, and their implementing regulations. While our mAb2 product candidates are considered biologics our SB 11285 is a drug. Biologics and drugs are also subject to other federal, state, local and foreign statutes and regulations. Failure to comply with the applicable U.S. regulatory requirements at any time during the product development process, approval process or after approval may subject an applicant to significant fines and penalties, including administrative or judicial actions. These actions could include, for example, the suspension or termination of clinical trials by the FDA or an IRB, the FDA’s refusal to approve pending marketing applications or supplemental applications, revocation of a biologics license or new drug approval, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, import detention, injunctions, civil penalties or criminal prosecution. Any such penalty or enforcement action could have a material adverse effect on us.

 

The process required by the FDA before a biologic or drug may be marketed in the United States generally involves the following:

 

completion of nonclinical laboratory tests and animal studies according to good laboratory practices, GLP, and applicable requirements for the humane use of laboratory animals or other applicable regulations;

 

28


 

submission of an Investigational New Drug (“IND”) application, which must become effective before clinical trials may begin;

 

approval of the protocol and related documentation by an independent IRB or ethics committee at each clinical trial site before each study may be initiated;

 

performance of adequate and well-controlled human clinical trials according to the FDA’s IND regulations, current good clinical practices, or “GCP”, and any additional requirements for the protection of human research subjects and their health information, to establish the safety and efficacy of the investigational product for each proposed indication;

 

submission to the FDA of a Biologics License Application (“BLA”) or a New Drug Application (“NDA”), for marketing approval, including payment of application user fees;

 

satisfactory completion of FDA pre-approval inspections of manufacturing facilities where the biologic or drug is produced to assess compliance with current good manufacturing practice (“GMP”) requirements to assure that the facilities, methods and controls are adequate to preserve the biologic’s or drug’s identity, strength, quality and purity;

 

potential FDA audits of the nonclinical study and clinical trial sites that generated the data in support of the BLA or NDA; and

 

FDA review and approval of the BLA or NDA, including satisfactory completion of an FDA advisory committee review of the product candidate, where appropriate or if applicable, which must occur before the biologic or drug can be marketed or sold in the United States.

 

The testing and approval process requires substantial time and financial resources, and we cannot be certain that any new approvals for our product candidates will be granted on a timely basis, if at all.

 

Preclinical Studies

 

Before testing any compound or biological product candidate in human subjects, a company must develop extensive preclinical data. Preclinical tests, also referred to as nonclinical studies, generally include laboratory evaluations of product compound or biological characteristics, chemistry and formulation as well as toxicological and pharmacological studies in several animal species to assess the potential quality, safety and activity of the product. Nonclinical studies must be performed in compliance with the FDA’s GLP regulations and, as applicable, the U.S. Department of Agriculture’s Animal Welfare Act and related regulations.

 

Prior to commencing the first clinical trial in humans, an IND application must be submitted to the FDA. A company must submit preclinical testing results, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. Some preclinical testing may continue even after the IND is submitted. An IND is a request for authorization from the FDA to ship an unapproved, investigational product in interstate commerce and to administer it to humans, and it must become effective before clinical trials may begin. The IND application automatically becomes effective 30 days after receipt by the FDA unless the FDA within the 30-day time period raises concerns or questions about the conduct of the clinical trial and places the trial on clinical hold. In such case, the IND application sponsor must resolve any outstanding concerns with the FDA before the clinical trial may begin. The FDA also may impose clinical holds on a product candidate at any time before or during clinical trials due to, among other considerations, unreasonable or significant safety concerns, inability to assess safety concerns, lack of qualified investigators, a misleading or materially incomplete investigator brochure, study design deficiencies, interference with the conduct or completion of a study designed to be adequate and well-controlled for the same or another investigational product, insufficient quantities of investigational product, lack of effectiveness or non-compliance. If the FDA imposes a clinical hold, studies may not recommence without FDA authorization and then only under terms authorized by the FDA.

 

Human Clinical Trials

 

29


 

Clinical trials involve the administration of a biological or drug product candidate to healthy volunteers or patients under the supervision of qualified investigators, generally physicians not employed by or under the study sponsor’s control. Clinical trials are conducted under protocols detailing, among other things, the objective of the clinical trial, dosing procedures, subject selection and exclusion criteria and the parameters to be used to monitor subject safety, including stopping rules that assure a clinical trial will be stopped if certain adverse events should occur. Each protocol and any amendments to the protocol must be submitted to the FDA as part of the IND.

 

Informed consent must also be obtained from each study subject. Further, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and related documentation, including the form and content of the informed consent form that must be signed by each study subject or his or her legal representative, before the trial commences at that site. The IRB for each site also monitors the clinical trial until completed. Regulatory authorities, an IRB, or the study sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the participants are being exposed to an unacceptable safety risk. Some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a data safety monitoring board, or DSMB. This group provides authorization as to whether or not a trial may move forward at designated check points based on access that only the group maintains to available data from the study.

 

A clinical trial sponsor is required to submit to the National Institutes of Health (“NIH”) for public posting on NIH’s clinical trial website details about certain active clinical trials and clinical trial results. Information related to the product, patient population, phase of investigation, study sites and investigators and other aspects of the clinical trial is made public as part of the registration of the clinical trial. Although sponsors are obligated to disclose the results of their clinical trials after completion, disclosure of the results can be delayed in some cases for up to two years after the date of completion of the trial. Competitors may use this publicly available information to gain knowledge regarding the progress of development programs. Failure to timely register a covered clinical study or to submit study results as provided for in the law can give rise to civil monetary penalties and also prevent the non-compliant party from receiving future grant funds from the federal government. The NIH’s Final Rule on ClinicalTrials.gov registration and reporting requirements became effective in 2017, and the government recently began enforcing those requirements against non-compliant clinical trial sponsors.

 

Human clinical trials are typically conducted in the following phases, which may overlap:

 

Phase 1 — the product candidate is initially given to healthy human subjects or patients and tested for safety, dosage tolerance, reactivity, absorption, metabolism, distribution and excretion. These trials may also provide early evidence of effectiveness. During Phase 1 clinical trials, sufficient information about the investigational product’s activity may be obtained to permit the design of well-controlled and scientifically valid Phase 2 clinical trials.

 

Phase 2 — clinical trials are conducted in a limited number of patients in the target population to identify possible adverse effects and safety risks, to evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.

 

Phase 3 — when Phase 2 evaluations demonstrate that a dosage range of the product appears effective and has an acceptable safety profile and provide sufficient information for the design of Phase 3 clinical trials, Phase 3 clinical trials are undertaken to provide statistically significant evidence of clinical efficacy and to further test for safety in an expanded patient population at multiple geographically dispersed clinical trial sites. Phase 3 clinical trials are performed after preliminary evidence suggesting effectiveness of the drug or biologic product candidate has been obtained, and they are intended to further evaluate dosage, effectiveness and safety, to establish the overall benefit-risk relationship of the investigational product, and to provide an adequate basis for product approval by the FDA.

 

All of these trials must be conducted in accordance with GCP requirements in order for the data to be considered reliable for regulatory purposes. Further, during all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data and clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to the FDA. Written IND safety reports must be promptly submitted to the FDA and the investigators for serious and unexpected adverse events, any findings from other studies, tests in laboratory animals or in vitro testing that suggests a significant risk for human subjects or any clinically important increase in the rate of a serious adverse reactions over that listed in the protocol or investigator brochure. The sponsor must submit such an IND safety report within 15 calendar days after the sponsor determines that the information qualifies for reporting. The sponsor also must

30


 

notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within seven calendar days after the sponsor’s initial receipt of the information. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all.

 

The FDA may require, or companies may pursue, additional clinical trials after a product is approved. These so-called Phase 4 clinical trials may be made a condition to be satisfied for continuing product approval. The results of Phase 4 clinical trials can confirm the effectiveness of a product candidate and can provide important safety information. Conversely, the results of Phase 4 clinical trials can raise new safety or effectiveness issues that were not apparent during the original review of the product, which may result in product restrictions or even withdrawal of product approval. If any of our products are subject to post-marketing requirements and commitments, there may be resource and financial implications for our business.

 

Marketing Application Submission and FDA Review

 

Assuming successful completion of required clinical testing and other requirements, the results of the preclinical studies and clinical trials, together with detailed information relating to the product’s chemistry, manufacture, controls and proposed labeling, among other things, are submitted to the FDA as part of either a BLA or an NDA requesting approval to market the biologic or drug product for one or more indications. A BLA in particular must contain proof of the biological product candidate’s safety, purity, potency and efficacy for its proposed indication or indications. In order to obtain approval to market a therapeutic product in the United States, the marketing application must provide data establishing to the FDA’s satisfaction, among other things, the safety and effectiveness of the investigational product for the proposed indication. Data can come from company-sponsored clinical trials intended to test the safety and effectiveness of a use of a product. In addition, the application may include supplemental data from a number of alternative sources, including studies initiated by investigators. Under federal law, the fee for the submission of an NDA or BLA is substantial (for example, for the 2022 fiscal year this application fee exceeds $3.1 million), and the sponsor of an approved NDA or BLA is also subject to an annual program fee, currently more than $369,000 per program. These fees are typically adjusted annually, but exemptions and waivers may be available under certain circumstances.

 

The FDA will initially review a BLA or NDA for completeness before it accepts the application for filing. Under the FDA’s procedures, the agency has 60 days from its receipt of a BLA/NDA, also called the filing period, to determine whether the application will be accepted for filing based on the agency’s threshold determination that the application is sufficiently complete to permit substantive review. The FDA may request additional information rather than accept a BLA or NDA for filing. In this event, the application must be resubmitted with the additional information. The resubmitted application is also subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review to determine, among other things, whether the proposed product is safe and effective for its intended use, whether it has an acceptable purity profile (for biologics), and whether the product is being manufactured in accordance with cGMP to assure and preserve the product’s identity, safety, strength, quality, potency and purity (as applicable depending on if the product is a drug or a biologic). The FDA has agreed to specified performance goals in the review process of BLAs and NDAs. Under such goals, 90% of new molecular entity (“NME”) NDAs and original BLAs, are meant to be reviewed within ten months from the date on which FDA accepts the NDA or BLA for filing, and 90% of applications for NMEs or new biological products that have been designated for “Priority Review” are meant to be reviewed within six months of the filing date. For applications seeking approval of drugs that are not NMEs, the ten-month and six-month review periods run from the date that FDA receives the application. The FDA may extend the review process and the Prescription Drug User Fee Act goal date for three additional months to consider new information or clarification provided by the applicant to address an outstanding deficiency identified by the FDA following the original submission. Moreover, despite these review goals, it is not uncommon for FDA review of a BLA or NDA to extend beyond the goal date.

Before approving a BLA or NDA, the FDA typically will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and are adequate to assure consistent production of the product within required specifications. These pre-approval inspections may cover all facilities associated with the BLA or NDA submission, including drug component manufacturing (e.g., active pharmaceutical ingredient manufacturers included within an NDA), finished product manufacturing, and control testing laboratories. Additionally, before approving a BLA or NDA, the FDA may inspect one or more clinical sites to assure compliance with GCP. If the FDA determines the application, manufacturing process or manufacturing facilities are not acceptable, it typically will outline the deficiencies and often will request additional testing or information. This may significantly delay further review of the application. If the FDA finds that a clinical site did not conduct the clinical trial in accordance with GCP, the FDA may, for example, determine the data generated by the clinical

31


 

site should be excluded from the primary efficacy analyses provided in the BLA or NDA. Additionally, notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

The FDA may refer applications for novel biological products, drug products or biological products that present difficult questions of safety or efficacy to an advisory committee, and it is required to refer an application for a novel drug to an advisory committee or explain why such referral was not made. Typically, an advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and, if so, under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making its approval decisions.

During the review and approval process, the FDA likely will re-analyze the clinical trial data, which could result in extensive discussions between the FDA and the applicant during the review process. In addition, as a condition of approval, the FDA may require an applicant to develop a risk evaluation and mitigation strategy, or REMS, if it determines that a REMS is necessary to assure the safe use of the drug or biological product. REMS use risk minimization strategies beyond the professional labeling to ensure that the benefits of the product outweigh the potential risks. When determining on a case-by-case basis whether a REMS is needed, the FDA will consider the size of the population likely to use the product, seriousness of the disease, expected benefit of the product, expected duration of treatment, seriousness of known or potential adverse events and whether the product is an NME. REMS can include medication guides, physician communication plans for healthcare professionals and elements to assure safe use (“ETASU”). ETASU may include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under certain circumstances, restricted distribution requirements, special clinical monitoring and/or the use of patient registries. The FDA may require a REMS before approval or post-approval if it becomes aware of a serious risk associated with use of the product. The requirement for a REMS can materially affect the potential market and profitability of an approved drug or biological product.

Based on the FDA’s evaluation of a BLA or an NDA and accompanying information, including the results of the inspection of the manufacturing facilities, the FDA may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing of the product with prescribing information for specific indications. A complete response letter generally outlines the deficiencies in the submission and may require substantial additional testing or information in order for the FDA to reconsider the application. If and when those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the BLA or NDA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six months depending on the type of information included. Even with submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. In addition, when a complete response letter is issued, the sponsor may elect to either resubmit the BLA or NDA or withdraw the application. Resubmitting a BLA or NDA in response to a complete response letter can add additional time to the approval process for a product.

Under the Pediatric Research Equity Act, or “PREA”, as amended, an initial BLA/NDA or certain supplements to a BLA/NDA for a novel product must contain data to assess the safety and effectiveness of the product candidate for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of pediatric data until after approval of the product for use in adults or full or partial waivers from the pediatric data requirement. Unless otherwise required by regulation, PREA does not typically apply to any therapeutic product for an indication for which orphan designation has been granted. A sponsor who is planning to submit a marketing application for a product that includes a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration is required to submit an initial Pediatric Study Plan (“PSP”), within sixty days of an end-of-Phase 2 meeting or, if there is no such meeting, as early as practicable before the initiation of the Phase 3 or Phase 2/3 clinical trial. The initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct, including trial objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information, and any request for a deferral of pediatric assessments or a full or partial waiver of the requirement to provide data from pediatric studies along with supporting information. The FDA and the sponsor must reach an agreement on the PSP. A sponsor can submit amendments to an agreed upon initial PSP at any time if changes to the pediatric plan need to be considered based on data collected from pre-clinical studies, early phase clinical trials or other clinical development programs.

The testing and approval process for a novel biologic or drug requires substantial time, effort and financial resources and this process may take several years to complete. Data obtained from clinical activities are not always conclusive and may be susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. The FDA may not grant approval on a timely basis or at all. We may encounter difficulties or unanticipated costs in our efforts to secure necessary governmental approvals, which could delay or preclude us from marketing our products.

If the FDA approves a product, it may limit the approved indications for use for the product, require that contraindications, warnings or precautions be included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess the biologic’s or drug’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms, including a REMS, which can materially affect the potential market and profitability of the product. The FDA may prevent or limit further marketing of a product based on the results of post-market studies or surveillance programs. After approval, many types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing requirements and FDA review and approval. Further, even after regulatory approval is obtained, later discovery of previously unknown problems with a product may result in restrictions on the product, including imposition of restrictions and conditions on product distribution, prescribing, or dispensing in the form of a REMS, requirements to conduct additional studies or trials, or even complete withdrawal of the product from the market. In addition, we cannot predict what adverse governmental regulations may arise from future U.S. or foreign governmental action.

Accelerated Approval Pathway

Products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may receive accelerated approval from the FDA and may be approved on the basis of adequate and well-controlled clinical trials establishing that the drug product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit. The FDA may also grant accelerated approval for such a drug or biologic when the product has an effect on an intermediate clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality, or ("IMM"), and that is reasonably likely to predict an effect on IMM or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require that a sponsor of a drug receiving accelerated approval perform post-marketing clinical trials to verify and describe the predicted effect on IMM or other clinical endpoint, and the product may be subject to expedited withdrawal procedures. Drugs and biologics granted accelerated approval must meet the same statutory standards for safety and effectiveness as those granted traditional approval.

 

For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, physical sign, or other measure that is thought to predict clinical benefit, but is not itself a measure of clinical benefit. Surrogate endpoints can often be measured more easily or more rapidly than clinical endpoints. An intermediate clinical endpoint is a measurement of a therapeutic effect that is considered reasonably likely to predict the clinical benefit of a drug, such as an effect on IMM. The FDA has limited experience with accelerated approvals based on intermediate clinical endpoints, but has indicated that such endpoints generally may support accelerated approval when the therapeutic effect measured by the endpoint is not itself a clinical benefit and basis for traditional approval, if there is a basis for concluding that the therapeutic effect is reasonably likely to predict the ultimate long-term clinical benefit of a drug.

The accelerated approval pathway is most often used in settings in which the course of a disease is long and an extended period of time is required to measure the intended clinical benefit of a drug, even if the effect on the surrogate or intermediate clinical endpoint occurs rapidly. For example, accelerated approval has been used extensively in the development and approval of drugs for treatment of a variety of cancers in which the goal of therapy is generally to improve survival or decrease morbidity and the duration of the typical disease course requires lengthy and sometimes large clinical trials to demonstrate a clinical or survival benefit.

 

The accelerated approval pathway is usually contingent on a sponsor’s agreement to conduct, in a diligent manner, additional post-approval confirmatory studies to verify and describe the drug’s clinical benefit. As a result, a product or therapeutic candidate approved on this basis is subject to rigorous post-marketing compliance requirements, including the completion of Phase 4 or post-approval clinical trials to confirm the effect on the clinical endpoint. Failure to conduct required post-approval studies, or to confirm the predicted clinical benefit of the product during post-marketing studies, would allow the FDA to withdraw approval of the drug. All promotional materials for product and therapeutic candidates being considered

33


 

and approved under the accelerated approval program are subject to prior review by the FDA. Lawmakers, FDA officials, and other stakeholders have recently been evaluating the accelerated approval program and have proposed potential reforms to improve certain aspects. In addition, over the past year several oncology sponsors have voluntarily withdrawn specific indications for their drug products that were being marketed pursuant to accelerated approval, and the FDA’s Oncology Center of Excellence launched an initiative called Project Confirm, aimed at promoting transparency in the area of accelerated approvals for oncology indications. Scrutiny of the accelerated approval pathway is likely to continue and may lead to legislative and/or administrative changes in the future.

 

U.S. Post-Approval Requirements

Any therapeutic products manufactured or distributed by us or on our behalf pursuant to FDA approvals will be subject to continuing regulation by the FDA, including requirements for record-keeping, reporting of adverse experiences with the biologic or drug, and submitting product deviation reports to notify the FDA of unanticipated changes in distributed products. In addition, all manufacturers are required to register their facilities with the FDA and certain state agencies and are subject to periodic pre-scheduled or unannounced inspections by the FDA and certain state agencies for compliance with cGMP standards and other laws. The cGMP regulations include requirements relating to organization of personnel, buildings and facilities, equipment, control of components and drug product containers and closures, production and process controls, packaging and labeling controls, holding and distribution, laboratory controls, records and reports and returned or salvaged products. This will require us and any third-party manufacturers to implement certain quality processes, manufacturing controls and documentation requirements in order to ensure that every product is safe for use, has the identity and strength it claims to have (for both a drug and a biologic) and meets the quality, purity and potency characteristics that it purports to have (for a biologic). There are continuing, annual program fee requirements for any marketed products, as well as new application fees for supplemental applications with clinical data.

We cannot be certain that we or our present or future suppliers will be able to comply with cGMP and other FDA regulatory requirements. If our present or future suppliers are not able to comply with these requirements, the FDA may halt our clinical trials, refuse to approve any BLA, NDA or other application, force us to recall a product from distribution, shut down manufacturing operations or withdraw approval of the BLA or NDA for that biologic or drug. Noncompliance with cGMP or other requirements can also result in issuance of warning letters, civil and criminal penalties, seizures, and injunctive action. The distribution of prescription products is subject to additional state requirements and regulations, including record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of prescription drug and biological products.

The FDA and other federal and state agencies closely regulate the labeling, marketing and promotion of biologics and drugs. While doctors may prescribe any product approved by the FDA for unapproved uses or patient populations (known as “off-label” uses), manufacturers may not market or promote such uses. In addition, biologic and drug promotional materials must be submitted to the FDA in conjunction with their first publication or first dissemination. (or, in the case of product candidates approved under the accelerated approval regulations, prior to dissemination). Further, if there are any modifications to the biologic or drug, including changes in indications, labeling or manufacturing processes or facilities, the applicant may be required to submit and obtain FDA approval of a new BLA or NDA or a BLA or NDA supplement, which may require the applicant to develop additional data or conduct additional preclinical studies and clinical trials. Failure to comply with these requirements can result in adverse publicity, warning letters, corrective advertising, injunctions, potential civil and criminal penalties, criminal prosecution or agreements with governmental agencies that materially restrict the manner in which a product approved by FDA may be promoted or distributed, among other potential consequences.

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act, or “PDMA”, which regulates the distribution of drugs and biological product samples at the federal level and sets minimum standards for the registration and regulation of prescription drug distributors by the states. Both the PDMA and state laws limit the distribution of prescription pharmaceutical product samples and impose requirements to ensure accountability in distribution. Most recently, the Drug Supply Chain Security Act, or “DSCSA”, was enacted with the aim of building an electronic system to identify and trace certain prescription drugs distributed in the United States, including most biological products. The DSCSA mandates phased-in and resource-intensive obligations for pharmaceutical manufacturers, wholesale distributors, and dispensers over a 10 year period that is expected to culminate in November 2023. From time to time, new legislation and regulations may be implemented that could significantly change the statutory provisions governing the approval, manufacturing and marketing of products regulated by the FDA. For example, the FDA released proposed regulations in February 2022 to amend the national standards for licensing of wholesale drug distributors by the states;

34


 

establish new minimum standards for state licensing third-party logistics providers; and create a federal system for licensure for use in the absence of a State program, each of which is mandated by the DSCSA. It is impossible to predict whether further legislative or regulatory changes will be enacted, or FDA regulations, guidance or interpretations changed or what the impact of such changes, if any, may be.

FDA’s Regulation of Companion Diagnostics

We believe that the success of certain of our product candidates, if approved, may depend, in part, on the development and commercialization of a companion diagnostic. Companion diagnostics identify patients who are most likely to benefit from a particular therapeutic product; identify patients likely to be at increased risk for serious side effects as a result of treatment with a particular therapeutic product; or monitor response to treatment with a particular therapeutic product for the purpose of adjusting treatment to achieve improved safety or effectiveness. Companion diagnostics are regulated as in vitro diagnostic medical devices by the FDA. In the United States, the FDCA and its implementing regulations, and other federal and state statutes and regulations govern, among other things, medical device design and development, preclinical and clinical testing, premarket clearance or approval, registration and listing, manufacturing, labeling, storage, advertising and promotion, sales and distribution, export and import and post-market surveillance. Unless an exemption applies, diagnostic tests generally require marketing clearance or approval from the FDA prior to commercialization. The two primary types of FDA marketing authorization applicable to a medical device are premarket notification, also called 510(k) clearance, and premarket approval (“PMA”).

To obtain 510(k) clearance for a medical device, or for certain modifications to devices that have received 510(k) clearance, a manufacturer must submit a premarket notification demonstrating that the proposed device is substantially equivalent to a previously cleared 510(k) device or to a pre-amendment device that was in commercial distribution before May 28, 1976, for which the FDA has not yet called for the submission of a PMA. The device upon which the premarket notification is based is referred to as the predicate device. In making a determination that the proposed device is substantially equivalent to a predicate device, the FDA assesses whether the proposed device is comparable to the predicate device(s) with respect to intended use, technology, design and other features which could affect safety and effectiveness. If the FDA determines that the proposed device is substantially equivalent to the predicate device or predicate devices, the proposed device may be cleared for marketing. The 510(k) premarket notification pathway generally takes from three to 12 months from the date the application is completed but can take significantly longer.

In contrast, PMA applications must be supported by valid scientific evidence, which typically requires extensive data, including technical, preclinical, clinical and manufacturing data, to demonstrate to the FDA’s satisfaction the safety and effectiveness of the device. For diagnostic tests, a PMA application typically includes data regarding analytical and clinical validation studies. As part of its review of the PMA, the FDA will conduct a pre-approval inspection of the manufacturing facility or facilities to ensure compliance with the Quality System Regulation, which requires manufacturers to follow design, testing, control, documentation and other quality assurance procedures analogous to the cGMP regulations for drugs and biologics. The FDA’s review of an initial PMA application is expected to take between six to ten months, although the process typically takes longer, and may require several years to complete. If the FDA evaluations of both the PMA application and the manufacturing facilities are favorable, the FDA will either issue an approval letter or an approvable letter, which usually contains a number of conditions that must be met in order to secure the final approval of the PMA. If the FDA’s evaluation of the PMA or manufacturing facilities is not favorable, the FDA will deny the approval of the PMA or issue a not approvable letter. A not approvable letter will outline the deficiencies in the application and, where practical, will identify what is necessary to make the PMA approvable. Once granted, PMA approval may be withdrawn by the FDA if compliance with post-approval requirements, conditions of approval or other regulatory standards is not maintained, or problems are identified following initial marketing.

In 2014, the FDA issued a final guidance document addressing the development and approval process for “In Vitro Companion Diagnostic Devices.” According to the agency, for novel therapeutic products that depend on the use of a diagnostic test and where the diagnostic device could be essential for the safe and effective use of the corresponding therapeutic product, the marketing application for the companion diagnostic device should be developed and approved or cleared contemporaneously with the therapeutic, although the FDA recognizes that there may be cases when contemporaneous development may not be possible. However, in cases where a drug cannot be used safely or effectively without the companion diagnostic, the FDA’s guidance indicates that the agency will generally not approve the drug without the approval or clearance of the diagnostic device. The FDA also issued a draft guidance in July 2016 setting forth the principles for co-development of an in vitro companion diagnostic device with a therapeutic product. The draft guidance

35


 

describes principles to guide the development and contemporaneous marketing authorization for the therapeutic product and its corresponding in vitro companion diagnostic. Subsequently, in December 2018, the FDA published a draft guidance entitled “Developing and Labeling In Vitro Companion Diagnostic Devices for a Specific Group or Class of Oncology Therapeutic Products” that is intended to facilitate class labeling on diagnostic tests for oncology therapeutic products, where scientifically appropriate. The draft guidance notes that in some cases, if evidence is sufficient to conclude that the companion diagnostic is appropriate for use with a specific group or class of therapeutic products, the companion diagnostic’s intended use should name the specific group or class of therapeutic products, rather than specific products.

Once cleared or approved, a companion diagnostic device must adhere to post-marketing requirements for medical device products including the requirements of FDA’s Quality System Regulation, adverse event reporting, recalls and corrections along with product marketing requirements and limitations. Like drug and biologic makers, companion diagnostic makers are subject to pre-scheduled or unannounced FDA inspections at any time, during which the FDA will conduct an audit of the product(s) and our facilities for compliance with its authorities.

U.S. Orphan Drug and European Orphan Medicinal Product Designation and Exclusivity

The U.S. Orphan Drug Act provides incentives for the development of products intended to treat rare diseases or conditions, which are generally diseases or conditions that affect fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States for which there is no reasonable expectation that the cost of developing and making a drug or biologic available in the United States for this type of disease or condition will be recovered from sales of the product. Orphan designation must be requested and granted by the FDA before submitting a BLA or NDA. The benefits of orphan drug designation include research and development tax credits and exemption from FDA prescription drug user fees. Orphan designation, however, does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. After the FDA grants orphan designation, the identity of the applicant, as well as the name of the therapeutic agent and its designated orphan use, are disclosed publicly by the FDA.

Under PREA, submission of a pediatric assessment is not typically required for pediatric investigation of a product that has been granted orphan drug designation. However, under the FDA Reauthorization Act of 2017, or “FDASIA,” the scope of the PREA was extended to require pediatric studies for products intended for the treatment of an adult cancer that are directed at a molecular target that are determined to be substantially relevant to the growth or progression of a pediatric cancer. In addition, the FDA finalized guidance in 2018 indicating that it does not expect to grant any additional orphan drug designation to products for pediatric subpopulations of common diseases. Nevertheless, FDA intends to still grant orphan drug designation to a drug or biologic that otherwise meets all other criteria for designation when it prevents, diagnoses or treats either (i) a rare disease that includes a rare pediatric subpopulation, (ii) a pediatric subpopulation that constitutes a valid orphan subset, or (iii) a rare disease that is in fact a different disease in the pediatric population as compared to the adult population. Generally, if a product that receives orphan designation receives the first FDA approval for the orphan indication, the product is entitled to orphan drug exclusivity, which means that for seven years, the FDA is prohibited from approving any other applications to market the same drug or biological product for the same indication, except in limited circumstances described further below. Orphan exclusivity does not block the approval of a different drug or biologic for the same rare disease or condition, nor does it block the approval of the same drug or biologic for different conditions. As a result, even if one of our product candidates receive orphan exclusivity, the FDA can still approve different drugs or biologics for use in treating the same indication or disease, which could create a more competitive market for us. Additionally, if a drug or biologic designated as an orphan product receives marketing approval for an indication broader than what was designated, it may not be entitled to orphan drug exclusivity.

Orphan exclusivity will not bar approval of another product with the same drug or biologic for the same condition under certain circumstances, including if a subsequent product with the same drug or biologic for the same condition is shown to be clinically superior to the approved product on the basis of greater efficacy or safety or a major contribution to patient care, or if the company with orphan drug exclusivity cannot assure the availability of sufficient quantities of the drug or biologic to meet the needs of persons with the disease or condition for which the drug or biologic was designated.

Similarly, the European Commission grants orphan medicinal product designation to products intended for the treatment, prevention or diagnosis of a disease that is life-threatening or chronically debilitating, affecting not more than five in 10,000 people in the European Union. In addition, orphan drug designation can be granted if the drug is intended for a life-threatening or chronically debilitating condition in the European Union and without incentives it is unlikely that returns from sales of the drug in the European Union would be sufficient to justify the investment required to develop the drug. In order to

36


 

receive orphan designation, there must also be no satisfactory method of diagnosis, prevention or treatment of the condition, or if such a method exists, the medicine in question must be of significant benefit to those affected by the condition. In addition, sponsors are required to submit to the EMA’s Pediatric Committee and comply with a pediatric investigation plan (“PIP”), in order to initiate pivotal clinical investigation and seek marketing authorization in the European Union, unless the particular product is eligible for a deferral or waiver of the requirement to submit a PIP. The requirement to submit a PIP is waived for specific medicines or classes of medicines that are likely to be ineffective or unsafe in part or all of the pediatric population, are intended for conditions that occur only in adults or do not represent a significant therapeutic benefit over existing treatments for pediatric patients.

Designated orphan medicinal products are entitled to a range of incentives during the development and regulatory review process, including scientific assistance for study protocols, a partial or total reduction in fees and eligibility for conditional marketing authorization. Once authorized, orphan medicinal products are entitled to ten years of market exclusivity in all European Union member states. However, marketing authorization may be granted to a similar medicinal product with the same orphan indication during the ten-year period with the consent of the marketing authorization holder for the original orphan medicinal product or if the manufacturer of the original orphan medicinal product is unable to supply sufficient quantities of such product. Marketing authorization may also be granted to a similar medicinal product with the same orphan indication if the similar product is established to be safer, more effective or otherwise clinically superior to the original orphan medicinal product. An European Union member state can request that the period of market exclusivity be reduced to six years if it can be demonstrated at the end of the fifth year of market exclusivity that the criteria for orphan designation no longer apply, such as where the medicine is sufficiently profitable. The period of market exclusivity may be extended for an additional two years for medicines that have also complied with an agreed PIP.

Pediatric Exclusivity

Pediatric exclusivity is another type of non-patent marketing exclusivity available in the United States and, if granted, it provides for the attachment of an additional six months of marketing protection to the term of any existing regulatory exclusivity for the approved drug or biological product. Under the Best Pharmaceuticals for Children Act (“BPCA”), certain therapeutic candidates may obtain an additional six months of exclusivity if the sponsor submits information requested in writing by the FDA, referred to as a Written Request, relating to the use of the active moiety of the product or therapeutic candidate in children. The data do not need to show the product to be effective in the pediatric population studied; rather, the additional protection is granted if the pediatric clinical study is deemed to have fairly responded to the FDA’s Written Request.

Although the FDA may issue a Written Request for studies on either approved or unapproved indications, it may only do so where it determines that information relating to that use of a product or therapeutic candidate in a pediatric population, or part of the pediatric population, may produce health benefits in that population. The issuance of a Written Request does not require the sponsor to undertake the described studies. Moreover, the additional six-month period exclusivity may be granted if the BLA or NDA sponsor submits pediatric data that fairly respond to the written request from the FDA for such data. The data do not need to show the product to be effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. This is not a patent term extension, but it effectively extends the regulatory period during which the FDA cannot approve a competitor's application for the same product and indication(s).

U.S. Reference Product Exclusivity for Biological Products

The Biologics Price Competition and Innovation Act of 2009 (“BPCIA”), enacted as part of the Patient Protection and Affordable Care Act in March 2010, created a unique licensure framework for biosimilars in the United States, which could ultimately subject our biological product candidates, if approved for marketing, to direct competition from potential future biosimilars. A biosimilar product is defined as one that is highly similar to a reference biological product notwithstanding minor differences in clinically inactive components and for which there are no clinically meaningful differences between the follow-on biological product and the reference product in terms of the safety, purity and potency of the product. To date, the FDA has approved a number of biosimilars, and numerous biosimilars have been approved in Europe. The FDA has also issued several guidance documents outlining its approach to reviewing and approving biosimilars and interchangeable biosimilars.

37


 

Under the BPCIA, a manufacturer may submit an abbreviated application for licensure of a biologic that is biosimilar to or interchangeable with an FDA-licensed reference biological product. This abbreviated approval pathway is intended to permit a biosimilar to come to market more quickly and less expensively than if a “full” BLA were submitted, by relying to some extent on the FDA’s previous review and approval of the reference biologic to which the proposed product is similar. Additionally, under the BPCIA, a biosimilar may be licensed as an interchangeable product upon a demonstration that the proposed product can be expected to produce the same clinical results as the reference product in any given patient, and, for products administered multiple times to an individual, that the product and the reference product may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biological product without such alternation or switch. Upon licensure by the FDA, an interchangeable biosimilar may be substituted for the reference product without the intervention of the healthcare provider who prescribed the reference product. The FDA approved the first interchangeable biosimilars, including an interchangeable monoclonal antibody biosimilar, in 2021.

Under the abbreviated approval pathway, the biosimilar applicant must demonstrate that the product is biosimilar based on data from (1) analytical studies showing that the biosimilar product is highly similar to the reference product; (2) animal studies (including toxicity); and (3) one or more clinical studies to demonstrate safety, purity and potency in one or more appropriate conditions of use for which the reference product is approved. In addition, the applicant must show that the biosimilar and reference products have the same mechanism of action for the conditions of use on the label, route of administration, dosage and strength, and the production facility must meet standards designed to assure product safety, purity and potency.

A reference biological product is granted 12 years of data exclusivity from the time of first licensure of the product, and the first approved interchangeable biologic product will be granted an exclusivity period of up to one year after it is first commercially marketed. If pediatric studies are performed and accepted by the FDA as responsive to a Written Request, as described above in the section called “Pediatric Exclusivity,” the 12-year exclusivity period will be extended for an additional six months.

In addition, the FDA will not accept an application for a biosimilar or interchangeable product based on the reference biological product until four years after the date of first licensure of the reference product. “First licensure” typically means the initial date the particular product at issue was licensed in the United States. Date of first licensure does not include the date of licensure of (and a new period of exclusivity is not available for) a supplement for the reference product for a subsequent application filed by the same sponsor or manufacturer of the reference product (or licensor, predecessor in interest or other related entity) for a change (not including a modification to the structure of the biological product) that results in a new indication, route of administration, dosing schedule, dosage form, delivery system, delivery device or strength or for a modification to the structure of the biological product that does not result in a change in safety, purity or potency. Therefore, one must determine whether a new product includes a modification to the structure of a previously licensed product that results in a change in safety, purity or potency to assess whether the licensure of the new product is a first licensure that triggers its own period of exclusivity. Whether a subsequent application, if approved, warrants exclusivity as the “first licensure” of a biological product is determined on a case-by-case basis with data submitted by the sponsor.

The BPCIA is complex and is still being interpreted and implemented by the FDA. In addition, recent government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation and meaning of the BPCIA is subject to significant uncertainty.

New Drug Exclusivity and Marketing Applications for Follow-on Drugs

In 1984, with passage of the Hatch-Waxman Amendments to the FDCA, Congress enacted Section 505(b)(2) of the FDCA and also established an abbreviated regulatory scheme authorizing the FDA to approve generic drugs that are shown to contain the same active ingredients as, and to be bioequivalent to, drugs previously approved by the FDA pursuant to NDAs. To obtain approval of a generic drug, an applicant must submit an abbreviated new drug application (“ANDA”), to the agency. An ANDA is a comprehensive submission that contains, among other things, data and information pertaining to the active pharmaceutical ingredient, bioequivalence, drug product formulation, specifications and stability of the generic drug, as well as analytical methods, manufacturing process validation data and quality control procedures. ANDAs are “abbreviated” because they cannot include preclinical and clinical data to demonstrate safety and effectiveness. Instead, in

38


 

support of such applications, a generic manufacturer must rely on the preclinical and clinical testing previously conducted for a drug product previously approved under an NDA, known as the reference-listed drug (“RLD”).

Specifically, in order for an ANDA to be approved, the FDA must find that the generic version is identical to the RLD with respect to the active ingredients, the route of administration, the dosage form, the strength of the drug and the conditions of use of the drug. At the same time, the FDA must also determine that the generic drug is “bioequivalent” to the innovator drug. Under the statute, a generic drug is bioequivalent to a RLD if “the rate and extent of absorption of the drug do not show a significant difference from the rate and extent of absorption of the listed drug.”

Upon approval of an ANDA, the FDA indicates whether the generic product is “therapeutically equivalent” to the RLD in its publication “Approved Drug Products with Therapeutic Equivalence Evaluations,” also referred to as the “Orange Book.” Physicians and pharmacists consider a therapeutic equivalent generic drug to be fully substitutable for the RLD. In addition, by operation of certain state laws and numerous health insurance programs, the FDA’s designation of therapeutic equivalence often results in substitution of the generic drug without the knowledge or consent of either the prescribing physician or patient.

In contrast, Section 505(b)(2) permits the filing of an NDA where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference. A Section 505(b)(2) applicant may eliminate the need to conduct certain preclinical or clinical studies, if it can establish that reliance on studies conducted for a previously approved product is scientifically appropriate. Unlike the ANDA pathway used by developers of bioequivalent versions of innovator drugs, which does not allow applicants to submit new clinical data other than bioavailability or bioequivalence data, the 505(b)(2) regulatory pathway does not preclude the possibility that a follow-on applicant would need to conduct additional clinical trials or nonclinical studies; for example, it may be seeking approval to market a previously approved drug for new indications or for a new patient population that would require new clinical data to demonstrate safety or effectiveness.

As part of the NDA review and approval process, applicants are required to list with the FDA each patent that has claims that cover the applicant’s product or method of therapeutic use. Upon approval of a new drug, each of the patents listed in the application for the drug is then published in the Orange Book. Drugs listed in the Orange Book can, in turn, be cited by potential follow-on competitors in support of approval of an ANDA or 505(b)(2) NDA.

When an ANDA applicant submits its application to the FDA, it is required to certify to the FDA concerning any patents listed for the reference product in the FDA’s Orange Book. Specifically, the applicant must certify that: (i) the required patent information has not been filed; (ii) the listed patent has expired; (iii) the listed patent has not expired but will expire on a particular date and approval is sought after patent expiration; or (iv) the listed patent is invalid or will not be infringed by the new product. Moreover, to the extent that the Section 505(b)(2) NDA applicant is relying on studies conducted for an already approved product, the applicant also is required to certify to the FDA concerning any patents listed for the approved product in the Orange Book to the same extent that an ANDA applicant would.

If the follow-on applicant does not challenge the innovator’s listed patents, FDA will not approve the ANDA or 505(b)(2) application until all the listed patents claiming the referenced product have expired. A certification that the new product will not infringe the already approved product’s listed patents, or that such patents are invalid, is called a Paragraph IV certification. If the follow-on applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days of the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA or 505(b)(2) NDA until the earlier of 30 months, expiration of the patent, settlement of the lawsuit, or a decision in the infringement case that is favorable to the ANDA/505(b)(2) applicant.

An ANDA or 505(b)(2) application also will not be approved until any applicable non-patent exclusivity listed in the Orange Book for the referenced product has expired. In particular, the Hatch-Waxman Amendments provided a period of five years of non-patent data exclusivity for a new drug containing a new chemical entity (“NCE”). For the purposes of this provision an NCE is a drug that contains no active moiety that has previously been approved by the FDA in any other NDA. An active moiety is the molecule or ion responsible for the physiological or pharmacological action of the drug substance. In cases where such NCE exclusivity has been granted, an ANDA or 505(b)(2) NDA may not be filed with the FDA until the

39


 

expiration of five years unless the submission is accompanied by a Paragraph IV certification, in which case the applicant may submit its application four years following the original product approval.

The FDCA also provides for a period of three years of exclusivity if an NDA includes reports of one or more new clinical investigations, other than bioavailability or bioequivalence studies, that were conducted by or for the applicant and are essential to the approval of the application. This three-year exclusivity period often protects changes to a previously approved drug product, such as a new dosage form, route of administration, combination or indication. Three-year exclusivity would be available for a drug product that contains a previously approved active moiety, provided the statutory requirement for a new clinical investigation is satisfied. Unlike five-year NCE exclusivity, an award of three-year exclusivity does not block the FDA from accepting ANDAs or 505(b)(2) NDAs seeking approval for generic versions of the drug as of the date of approval of the original drug product; rather this three-year exclusivity covers only the conditions of use associated with the new clinical investigations and does not prohibit the FDA from approving follow-on applications for drugs containing the original active agent.

The FDA typically makes decisions about awards of data exclusivity shortly before an original NDA or efficacy supplement is approved. Five-year and three-year exclusivity also will not delay the submission or approval of a traditional NDA filed under Section 505(b)(1) of the FDCA. However, an applicant submitting a traditional NDA would be required to either conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Patent Term Extension

Depending upon the timing, duration and specifics of FDA approval of our drug candidate SB 11285 or any future drug candidates, some of our U.S. patents may be eligible for limited patent term extension under other provisions of the Hatch-Waxman Amendments. These patent term extensions permit a patent restoration term of up to five years as compensation for any patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND, and the submission date of an NDA, plus the time between the submission date of an NDA and the approval of that application. Only one patent applicable to an approved drug is eligible for the extension, and the extension must be applied for prior to expiration of the patent. The United States Patent and Trademark Office (“USPTO”) in consultation with the FDA, reviews and approves the application for any patent term extension or restoration.

Coverage, Pricing, and Reimbursement

In both domestic and foreign markets, sales of any products for which we may receive regulatory approval will depend in part upon the availability of coverage and adequate reimbursement from third-party payors. Coverage also may be more limited than the purposes for which the product is approved by the FDA or regulatory authorities in other countries. In the United States, such third-party payors include government health programs, such as Medicare and Medicaid, private health insurers and managed care providers and other organizations. Coverage decisions may depend upon clinical and economic standards that disfavor new drug and biological products when more established or lower cost therapeutic alternatives are already available or subsequently become available. Assuming coverage is granted, the reimbursement rates paid for covered products might not be adequate and eligibility for reimbursement does not imply that any product will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim payments for new products, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Even if favorable coverage status and adequate reimbursement rates are attained, less favorable coverage policies and reimbursement rates may be implemented in the future. The marketability of any products for which we may receive regulatory approval for commercial sale may suffer if the government and other third-party payors fail to provide coverage and adequate reimbursement to allow us to sell such products on a competitive and profitable basis. For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs and biologics. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization. For example, under these circumstances, physicians may limit how much or under what circumstances they will prescribe or administer our future therapeutic products and patients may decline to purchase such products. This, in turn, could affect our ability to successfully commercialize our future therapeutic products and impact our profitability, results of operations, financial condition, and future success.

40


 

The market for any product candidates for which we may receive regulatory approval in the United States will depend significantly on the degree to which these products are listed on third-party payors’ drug formularies or lists of medications for which third-party payors provide coverage and reimbursement. The industry competition to be included on such formularies often leads to downward pricing pressures on pharmaceutical companies. Also, third-party payors may refuse to include a particular branded drug or biologic on their formularies or otherwise restrict patient access to a branded drug when a less costly generic equivalent, biosimilar product, or other alternative is available. In addition, no uniform coverage and reimbursement policy exists, and coverage and reimbursement can differ significantly from payor to payor. As such, one third-party payor’s determination to provide coverage does not assure that other third-party payors will also provide coverage. Third-party payors often rely on Medicare coverage policy and payment limitations in setting their own reimbursement rates but also have their own methods to individually establish coverage and reimbursement policies. As a result, obtaining coverage and adequate reimbursement can be a time-consuming and costly process. We may be required to provide scientific and clinical support for the use of any of its approved biological products to each third-party payor separately with no assurance that approval would be obtained, and we may need to conduct expensive pharmacoeconomic studies in order to demonstrate the cost-effectiveness of our future therapeutic products. We cannot be certain that our product candidates will be considered cost-effective by any private or government payors. This process could delay the market acceptance of any product candidates for which we may receive approval and could have a negative effect on our future revenues and operating results.

In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. In some countries, the pricing of prescription pharmaceuticals is subject to government control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain coverage and adequate reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product to other available therapies. Historically, therapeutic candidates launched in the European Union do not follow price structures of the United States and generally tend to be priced significantly lower.

Additionally, the containment of healthcare costs has become a priority of federal and state governments and the prices of therapeutics have been a focus in this effort. The United States government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic and biosimilar products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our future net revenue and operating results. In addition, companion diagnostic tests require coverage and reimbursement separate and apart from the coverage and reimbursement for their companion pharmaceutical or biological products. Similar challenges to obtaining coverage and reimbursement for the pharmaceutical or biological products apply to companion diagnostics.

Anti-Kickback, False Claims, Physician Payments Sunshine Acts and Other U.S. Healthcare Laws

In addition to FDA restrictions on marketing, several other types of U.S. state and federal laws are relevant to our current and future business operations, including broadly applicable fraud and abuse and other healthcare laws, including the anti-kickback and false claims laws, privacy and security laws and transparency laws. We are subject to these laws or will become subject to them in the future, and they may affect our business.

The U.S. federal Anti-Kickback Statute prohibits, among other things, any person or entity from knowingly and willfully soliciting, receiving, offering or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual for an item of service, or the purchase, lease, order or recommendation of any good or service, for which payment may be made under federal healthcare programs such as the Medicare and Medicaid programs. The federal Anti-Kickback Statute is subject to evolving interpretations. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers, formulary managers and other individuals and entities on the other hand, and the government has enforced the federal Anti-Kickback Statute to reach large settlements with healthcare companies based on sham consulting and other financial arrangements with physicians. A person or entity does not need to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the U.S. federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act, described below. There are a number of statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution or other regulatory sanctions; however, the exceptions and safe harbors are drawn narrowly, and practices that do not fit

41


 

squarely within an exception or safe harbor may be subject to scrutiny. Moreover, in November 2020, the U.S. Department of Health and Human Services (“HHS”) finalized significant changes to the regulations implementing the Anti-Kickback Statute, as well as the civil monetary penalty rules regarding beneficiary inducements, with the goal of offering the healthcare industry more flexibility and reducing the regulatory burden associated with those fraud and abuse laws, particularly with respect to value-based arrangements among industry participants.

The federal civil and criminal false claims laws, including the civil False Claims Act, and civil monetary penalty laws, prohibit, among other things, any person from knowingly presenting, or causing to be presented, a false or fraudulent claim for payment to the U.S. government, or knowingly making, or causing to be made or used, a false record or statement material to a false or fraudulent claim to the U.S. government, or from knowingly making a false statement to avoid, decrease or conceal an obligation to pay money to the U.S. government. Actions under these laws may be brought by the Attorney General or as a qui tam action by a private individual in the name of the government. Many pharmaceutical and other healthcare companies have faced investigations and lawsuits, including those brought by individuals through qui tam actions, for a variety of allegedly improper promotional and marketing activities, including inflating drug prices they report to pricing services, which in turn were used by the government to set Medicare and Medicaid reimbursement rates; providing free product to customers with the expectation that the customers would bill federal programs for the product; providing consulting fees and other benefits to physicians to induce them to prescribe products; or engaging in promotion for “off-label” uses.

The Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and its implementing regulations (“HIPAA”), created new federal, civil and criminal statutes that prohibit, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a criminal violation of these laws. HIPAA also imposes obligations on certain covered entity healthcare providers, health plans and healthcare clearinghouses as well as their business associates that perform certain services involving the use or disclosure of individually identifiable health information, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information. The 2009 amendments to HIPAA made the law’s privacy and security standards directly applicable to “business associates,” defined as independent contractors or agents of covered entities that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. The amendments also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions.

The Physician Payments Sunshine Act, enacted as part of the Affordable Care Act in 2010 and implemented by HHS as the Open Payments Program, among other things, requires certain manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program to track payments and other transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists, chiropractors, and certain advanced non-physician healthcare practitioners) and teaching hospitals as well as physician ownership and investment interests held by physicians and their immediate family members, and to publicly report such data annually to HHS. Manufacturers subject to the Open Payments Program must submit a report on or before the 90th day of each calendar year disclosing reportable payments made in the previous calendar year.

There are also analogous state laws and regulations, such as state anti-kickback and false claims laws, that may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers or that apply regardless of payor. Several states now require pharmaceutical companies to report expenses relating to the marketing and promotion of pharmaceutical products in those states and to report gifts and payments to individual healthcare providers in those states. Some of these states also prohibit certain marketing related activities including the provision of gifts, meals, or other items to certain healthcare providers. Some states also require pharmaceutical companies to implement compliance programs or marketing codes and report information on the pricing of certain drugs. Certain state and local laws also require the registration of pharmaceutical sales representatives, and newly

42


 

emerging state laws govern the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of available statutory exceptions and regulatory exemptions, it is possible that some of our future business activities could be subject to challenge under one or more of such laws. If our operations were found to be in violation of any of the federal or state laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including significant criminal or civil penalties, damages, disgorgement, fines, imprisonment, exclusion from participation in government programs, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product approvals, private “qui tam” actions brought by individual whistleblowers in the name of the government, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

To the extent that any of our products are in the future sold in a foreign country, we may be subject to similar foreign laws and regulations, which may include, for instance, applicable anti-fraud and abuse laws, and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals.

U.S. Healthcare Reform

The United States and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell our product candidates profitably, even if we are approved for sale. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.

In March 2010, the Affordable Care Act (“ACA”), was passed, which substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the U.S. pharmaceutical industry. The ACA, among other things, subjected biological products to potential competition by lower-cost biosimilars, created a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations, established annual fees and taxes on manufacturers of certain branded prescription drugs, and created a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

Members of the U.S. Congress have expressed intent to pass legislation or adopt executive orders to fundamentally change or repeal parts of the ACA, and since its enactment, there have been judicial and Congressional challenges to the law, and as a result certain sections have not been fully implemented or effectively repealed. However, following several years of litigation in the federal courts, in June 2021, the U.S. Supreme Court upheld the ACA when it dismissed a legal challenge to the ACA’s constitutionality. Further legislative and regulatory changes under the ACA remain possible, although the new federal administration under President Biden has signaled that it plans to build on the ACA and expand the number of people who are eligible for health insurance subsidies under it. It is unknown what form any such changes or any law would take, and how or whether it may affect the biopharmaceutical industry as a whole or our business in the future. We expect that changes or additions to the ACA, the Medicare and Medicaid programs, such as changes allowing the federal government to directly negotiate drug prices, and changes stemming from other healthcare reform measures, especially with regard to healthcare access, financing or other legislation in individual states, could have a material adverse effect on the health care industry in the United States.

The Biden Administration has indicated that lowering prescription drug prices is a priority. For example, in July 2021, President Biden issued a sweeping executive order on promoting competition in the American economy that includes several mandates pertaining to the pharmaceutical and health care insurance industries. Among other things, the executive order directs the FDA to work towards implementing a system for importing drugs from Canada (following on a Trump administration notice-and-comment rulemaking on Canadian drug importation that was finalized in October 2020). The

43


 

Biden order also called on HHS to release a comprehensive plan to combat high prescription drug prices, and it includes several directives regarding the Federal Trade Commission’s oversight of potentially anticompetitive practices within the pharmaceutical industry. The drug pricing plan released by HHS in September 2021 in response to the executive order makes clear that the Biden Administration supports aggressive action to address rising drug prices, including allowing HHS to negotiate the cost of Medicare Part B and D drugs, but such significant changes will require either new legislation to be passed by Congress or time-consuming administrative actions.

Other legislative changes have been proposed and adopted in the United States since the ACA that affect health care expenditures. These changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013 and will remain in effect through 2030 unless additional Congressional action is taken. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) which was signed into law on March 27, 2020, designed to provide financial support and resources to individuals and businesses affected by the COVID-19 pandemic, suspended the 2% Medicare sequester from May 1, 2020 through December 31, 2020, and extended the sequester by one year, through 2030, in order to offset the added expense of the 2020 cancellation. Congress subsequently extended the sequester suspension period to June 30, 2022, with a 1% sequester in effect from April 1, 2022 to June 30, 2022.

Moreover, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. For example, on December 20, 2019, President Trump signed the Further Consolidated Appropriations Act for 2020 into law (P.L. 116-94) that includes a piece of bipartisan legislation called the Creating and Restoring Equal Access to Equivalent Samples Act of 2019 (the “CREATES Act”). The CREATES Act aims to address the concern articulated by both the FDA and others in the industry that some brand manufacturers have improperly restricted the distribution of their products, including by invoking the existence of a REMS for certain products, to deny generic and biosimilar product developers access to samples of brand products. Because generic and biosimilar product developers need samples to conduct certain comparative testing required by the FDA, some have attributed the inability to timely obtain samples as a cause of delay in the entry of generic and biosimilar products. To remedy this concern, the CREATES Act establishes a private cause of action that permits a generic or biosimilar product developer to sue the brand manufacturer to compel it to furnish the necessary samples on “commercially reasonable, market-based terms.” Whether and how generic and biosimilar product developments will use this pathway, as well as the likely outcome of any legal challenges to provisions of the CREATES Act, remain highly uncertain and its potential effects on our future commercial products are unknown.

 

In addition, on May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new product candidates that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its product candidates available to eligible patients as a result of the Right to Try Act. However, in 2020 the FDA published a notice of proposed rulemaking that would require manufacturers who do so to make annual reports of those programs to FDA, and the agency plans to publish the final rule in March 2022.

At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In December 2020, the U.S. Supreme Court held unanimously that federal law does not preempt the states’ ability to regulate pharmaceutical benefit managers (“PBMs”) and other members of the healthcare and pharmaceutical supply chain, an important decision that may lead to further and more aggressive efforts by states in this area. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing.

We expect that these and other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved drug, which could have

44


 

an adverse effect on customers for our product candidates. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors.

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products. Such reforms could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop product candidates.

Foreign Regulation

In addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our product candidates. Whether or not we obtain FDA approval for a product candidate, we must obtain approval from the comparable regulatory authorities of foreign countries or economic areas, such as the European Union and the United Kingdom, before we may commence clinical trials or market products in those countries or areas. The approval process and requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from place to place, and the time to obtain approval in foreign jurisdictions may be longer or shorter than that required for FDA approval.

 

In the European Union, for example, under the new Clinical Trials Regulation, which became effective in January 2022, a sponsor submits a clinical trial application (“CTA”) through a centralized application procedure where one European Union Member State’s competent authority takes the lead in reviewing part I of the application, which contains scientific and medicinal product documentation, and the other national authorities only have limited involvement. Part II of the application, which contains the national and patient-level documentation, is assessed individually by each European Union Member State. Any substantial changes to the trial protocol or other information submitted with the CTA must be notified to or approved by the relevant competent authorities and ethics committees. In all cases, the clinical trials are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki. Medicines used in clinical trials must be manufactured in accordance with good manufacturing practices. Other national and European Union-wide regulatory requirements may also apply.

 

To obtain regulatory approval of an investigational drug or biological product under European Union regulatory systems, we must submit a marketing authorization application either under the so-called centralized or national authorization procedures.

Centralized procedure

The centralized procedure provides for the grant of a single marketing authorization by the European Commission following a favorable opinion by the EMA that is valid in all European Union member states, as well as Iceland, Liechtenstein and Norway. The centralized procedure is compulsory for medicines produced by specified biotechnological processes, products designated as orphan medicinal products and products with a new active substance indicated for the treatment of specified diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative disorders or autoimmune diseases, other immune dysfunctions and viral diseases. The centralized procedure is optional for other products that represent a significant therapeutic, scientific or technical innovation, or whose authorization would be in the interest of patients in the European Union, or which contain a new active substance for indications other than those specified to be compulsory.

 

The national authorization, or decentralized, procedure is available to applicants who wish to market a product in specific European Union member states where such product has not received marketing approval in any European Union member states before. The decentralized procedure provides for an applicant to apply to one-member state to assess the application (the reference member state) and specifically list other member states in which it wishes to obtain approval (concerned member states). Under this procedure, an applicant submits an application based on identical dossiers and related materials, including a draft summary of product characteristics, and draft labelling and package leaflet, to the reference member state and each concerned member state. The reference member state prepares a draft assessment report and drafts of the related materials within 210 days after receipt of a valid application which is then reviewed and approved commented on by the concerned member states. Within 90 days of receiving the reference member state’s assessment report and related materials, each concerned member state must decide whether to approve the assessment report and related materials.

 

45


 

Following its departure from the European Union and the expiration of the transitional period, the United Kingdom adopted a decentralized and mutual recognition reliance procedure for marketing authorizations that allows the United Kingdom’s clinical trial regulator, the Medicines and Healthcare products Regulatory Agency ("MHRA"), to consider marketing authorizations granted in the European Union or the three additional European Economic Area countries. However, additional requests for information may arise and additional time may be required with respect to applications for marketing authorizations in the United Kingdom using these procedures. For other countries outside of the European Union, such as countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, again, the clinical trials are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

 

If we or our potential collaborators fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Other Regulations

We are also subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. We may incur significant costs to comply with such laws and regulations now or in the future.

We are also subject to privacy laws in the jurisdictions in which we are established or in which we sell or market our products or run clinical trials. For example, we and our European Union-based subsidiaries are subject to Regulation (EU) 2016/679, the General Data Protection Regulation (“GDPR”), in relation to our collection, control, processing and other use of personal data (i.e., data relating to an identifiable living individual) to the extent that the activities are by a data controller or processor established in the European Union or where the individuals who are being monitored are based in the European Union. We process personal data in relation to participants in our clinical trials, including the health and medical information of these participants. The GDPR is directly applicable in each European Union member state, however, it provides that European Union member states may introduce further conditions, including limitations which could limit our ability to collect, use and share personal data (including health and medical information), or could cause our compliance costs to increase, ultimately having an adverse impact on our business. The GDPR imposes onerous accountability obligations requiring data controllers and processors to maintain a record of their data processing and implement policies as part of its mandated privacy governance framework. It also requires data controllers to be transparent and disclose to data subjects (in a concise, intelligible and easily accessible form) how their personal information is to be used; imposes limitations on retention of personal data; clarifies that data protection rules apply in full to pseudonymized (i.e., key-coded) data; introduces mandatory data breach notification requirements; and sets higher standards for data controllers to demonstrate that they have obtained valid consent for certain data processing activities. We are also subject to European Union rules with respect to cross-border transfers of personal data out of the European Union and European Economic Area. We are subject to the supervision of local data protection authorities in those European Union jurisdictions where we are established or otherwise subject to the GDPR. Fines for certain breaches of the GDPR can be significant: up to the greater of €20 million or 4% of total global annual turnover. In addition to the foregoing, a breach of the GDPR or other applicable privacy and data protection laws and regulations could result in regulatory investigations, reputational damage, orders to cease/ change our use of data, enforcement notices, or potential civil claims including class action type litigation. Following Brexit, the United Kingdom has incorporated the GDPR into its own data protection laws, and substantially equivalent risks also apply in the United Kingdom.

Item 1A. Risk Factors.

We have identified the following risks and uncertainties that may have a material adverse effect on our business, financial condition or results of operations. The risks described below are not the only ones we face. Additional risks not presently known to us or other factors not perceived by us to present significant risks to our business at this time may also significantly impair our business operations. Our business could be harmed by any of these risks. Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all other information contained in this Annual Report on Form 10-K, including our condensed consolidated financial statements and the related notes, before making any decision to purchase our common stock. If any of the possible adverse events described below actually occurs, we may be unable to conduct our business as currently planned and our prospects, financial condition, operating results and cash flows could be materially harmed. In addition, the trading price of our common stock could decline due to the occurrence of any of the events described below, and you may lose all or part of your investment. In assessing these risks, you should refer to the other information contained in this Annual Report on Form 10-K, including our condensed consolidated financial statements and related notes.

Summary Risk Factors

We are subject to a number of risks that if realized could affect our business, financial condition, results of operations and cash flows. As a clinical stage drug development company, certain elements of risk are inherent to our business. Accordingly, we encounter risks as part of the normal course of our business. Some of the more significant challenges and risks include the following:

We are a clinical-stage immuno-oncology company and have incurred significant losses since our inception. We expect to incur losses for the foreseeable future and may never achieve or maintain profitability.
We will need substantial additional funding to complete the development and commence commercialization of our product candidates. Failure to obtain this necessary capital at acceptable terms and when needed may force us to delay, reduce or eliminate out product development programs or commercialization efforts.
We have identified conditions and events that raise substantial doubt about our ability to continue as a going concern, which may hinder our ability to obtain future financing.
If we are unable to advance our current or future product candidates through clinical trials, obtain marketing approval and ultimately commercialize any product candidates we develop, or if we experience significant delays in doing so, our business will be materially harmed.
Interim, topline, and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.
Our product candidates may have serious adverse, undesirable, or unacceptable side effects that may delay or prevent marketing approval.
We may find it difficult to enroll subjects in our clinical trials, which could delay or prevent us from proceeding with clinical trials of our product candidates.
We face significant competition for our drug discovery and development efforts, and if we do not compete effectively, our commercial opportunities will be reduced or eliminated.
We rely, and expect to continue to rely, on third parties, including independent clinical investigators, contracted laboratories and CROs, to conduct our preclinical studies and clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed
The regulatory approval processes of the FDA, the EMA, the MHRA, and other comparable foreign regulatory authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be substantially harmed.
We may become exposed to costly and damaging liability claims, either when testing our product candidates in the clinic or at the commercial stage,

48


 

Due to our limited resources and access to capital, we must, and have in the past decided to, prioritize development of certain product candidates over other potential product candidates.
The successful commercialization of our product candidates will depend in part on the extent to which governmental authorities and health insurers establish coverage and adequate reimbursement levels, as well as pricing policies.
The future commercial success of our product candidates will depend on the degree of market acceptance of our potential therapeutic products among physicians, patients, third-party payors and the medical community.
Our business operations and current and future relationships with clinical investigators, healthcare professionals, consultants, third-party payors and customers may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws, health information privacy and security laws, and other healthcare laws. If we are unable to comply, or has not fully complied, with such laws, we could face substantial penalties.
Adverse events in the field of immuno-oncology could damage public perception of our current or future therapeutic product candidates and negatively affect our business.
The COVID-19 pandemic has adversely affected many companies in the biotechnology industry and may adversely affect our business.
The Ukraine conflict may adversely affect many companies in the biotechnology industry, in particular with respect to timely enrollment and data collection in planned and ongoing clinical trials and has adversely affected our business, in particular in relation to planned and ongoing clinical trials.
We rely on patents and other intellectual property rights to protect our product candidates and our modular antibody technology platform, the enforcement, defense and maintenance of which may be challenging and costly.
We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and unsuccessful, and issued patents relating to one or more of our product candidates or our modular antibody technology platform could be found invalid or unenforceable if challenged in court.
Intellectual property rights of third parties could adversely affect our ability to commercialize our product candidates,
We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property or claiming ownership of what we regard as our own intellectual property.
The manufacture of biotechnology products is complex, and manufacturers often encounter difficulties in production. We rely on third parties to supply and manufacture our product candidates, and we expect to continue to rely on third parties to manufacture our products, if approved. If we or any of our third-party manufacturers encounter such difficulties, or otherwise fail to comply with their contractual obligations, the development or commercialization of our product candidates could be delayed or stopped.
Our future growth and ability to compete depends on retaining our key personnel and recruiting additional qualified personnel.
Our business is subject to economic, political, regulatory, and other risks associated with international operations.
Our business and operations would suffer in the event of computer system failures, cyber-attacks or a deficiency in our, or our collaborators’ or third-party vendors’, cyber-security.
Our employees, independent contractors, vendors, principal investigators, CROs and consultants may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading.

 

The above list is not exhaustive, and we face additional challenges and risks. Please carefully consider all of the information in this Form 10-K including matters set forth in this “Risk Factors” section.

Risks Related to our Financial Position and Capital Requirements

We are a clinical-stage immuno-oncology company and have incurred significant losses since our inception. We expect to incur losses for the foreseeable future and may never achieve or maintain profitability.

We are a clinical-stage immuno-oncology company with a limited operating history. We incurred net losses of $31.3 million for the year ended December 31, 2021 and $25.6 million for the year ended December 31, 2020. As of December 31, 2021, we had an accumulated loss $78.5 million. Our losses have resulted principally from expenses incurred in research and development, preclinical testing and clinical development of our therapeutic product candidates as well as expenses incurred for research programs and from general and administrative costs associated with our operations. We expect to continue to incur significant and increasing operating losses for the foreseeable future as we continue our clinical trial plans, research and development efforts and seek to obtain regulatory approval and commercialization of our tetravalent bispecific antibody (“mAb2”) product candidates, and SB 11285, and we do not know whether or when we will become profitable. Management believes that its existing cash and cash equivalents at December 31, 2021 will fund our current operating plan into February 2023. We have concluded that substantial doubt exists about our ability to continue as a going concern for a period of at least twelve months from the issuance date of the financial statements. Our losses, among other things, will continue to cause our working capital and shareholders’ equity to decrease. We anticipate that our expenses will increase substantially if and as we:

continue to develop and conduct clinical trials for our current product candidates, FS118, FS222, FS120, and SB 11285;
continue the research and development of our product candidates, including completing preclinical studies;
discover and develop additional mAb2 product candidates and make further investments in our modular antibody technology platform;
seek regulatory approvals for any product candidates that successfully complete clinical trials;
experience any delays or encounter any issues with any of the above, including but not limited to failed studies, complex results, safety issues or other regulatory challenges;
establish a sales, marketing and distribution infrastructure and scale-up manufacturing capabilities, whether alone or with third parties, to commercialize any product candidates for which we may obtain regulatory approval, if any;
maintain, expand and protect our intellectual property portfolio, including litigation costs associated with defending against alleged patent infringement claims;
add clinical, scientific, operational, financial and management information systems and personnel, including personnel to support our product development and potential future commercialization efforts;
expand our operations in the United States, Europe and other geographies; and
incur additional legal, accounting and other expenses associated with operating as a public company.

To date, we have funded our operations through public offering and private placements of equity securities and upfront and milestone payments and expense reimbursement payments received from our collaborators. We have invested substantially all of our financial resources and efforts to developing our mAb2 product candidates and SB 11285 in immuno-oncology, building our intellectual property portfolio, developing our supply chain, conducting business planning, licensing our technology to our collaborators, raising capital and providing general and administrative support for these operations. We do not currently have any approved products and have never generated any revenue from product sales.

To become and remain profitable, we must succeed in developing and eventually commercializing products that generate significant revenue. This will require us to be successful in a range of challenging activities, including completing preclinical testing and clinical trials of our product candidates supportive of product approval, discovering and developing additional mAb2 or small-molecule drug product candidates, obtaining regulatory approval for any product candidates that successfully complete clinical trials, establishing manufacturing and marketing capabilities and ultimately selling any products for which we may obtain regulatory approval. We are only in the preliminary stages of most of these activities. We may never succeed in these activities and, even if we do, may never generate revenue that is significant enough to achieve or maintain profitability. Even if one or more of the product candidates that we develop is approved for commercial sale, we anticipate incurring significant costs associated with commercializing any approved product candidate. Our expenses could increase

50


 

beyond current expectations if we are required by the FDA, the EMA, the MHRA, or other comparable foreign regulatory agencies to perform clinical trials or studies in addition to those that we currently anticipate. Even if we are able to generate revenue from the sale of any approved products, we may not become profitable and may need to obtain additional funding to continue operations.

Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable could impair our ability to raise capital, expand our business, maintain our research and development efforts or continue our operations and you could lose some or all of your investment.

Our limited operating history may make it difficult to evaluate the success of our business to date and to assess our future viability.

Since inception, we have invested most of our resources in developing our modular antibody technology platform, our mAb2technology and mAb2 product candidates, building our intellectual property portfolio, conducting business planning, licensing our technology to our collaborators, raising capital and providing general and administrative support for these operations. Our most advanced mAb2 product candidate, FS118, is currently being evaluated in proof-of-concept Phase 2 trials in PD-1/PD-L1 acquired resistance head and neck cancer patients and checkpoint inhibitor naive NSCLC and DLBCL. We have not yet demonstrated our ability to successfully complete Phase 2 clinical trials or any Phase 3 or other pivotal clinical trials, obtain regulatory approvals, manufacture a commercial-scale product or arrange for a third party to do so on our behalf or conduct sales and marketing activities necessary for successful product commercialization. In addition, given our limited operating history, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors in achieving our business objectives. Additionally, we expect our financial condition and operating results to continue to fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history or more experience developing product candidates.

We will need substantial additional funding in order to complete the development and commence commercialization of our product candidates. Failure to obtain this necessary capital at acceptable terms and when needed may force us to delay, reduce or eliminate out product development programs or commercialization efforts.

We expect our expenses to increase in connection with our ongoing activities, particularly as we complete the proof-of-concept Phase 2 clinical trials of FS118 and Phase 1 trials for FS222, FS120, and SB 11285 and initiate later-stage clinical development, and continue to research, develop and initiate clinical trials for any other product candidates. In addition, if we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution.

Furthermore, we have incurred, and expect to continue to incur, additional costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our product development programs or any future commercialization efforts.

The Company has incurred significant losses and has an accumulated deficit of $78.5 million as of December 31, 2021. We expect to incur substantial losses in the foreseeable future as we conduct and expand our research and development and pre-clinical and clinical activities. We do not expect that our $78.5 million of existing cash as of December 31, 2021 will enable us to fund our operating expenses and capital expenditure requirements for at least the next twelve months from the date of filing this Annual Report on Form 10K. We will need to raise additional capital to complete the development and commercialization of FS118, FS222, FS120 and SB 11285, if approved, and may also need to raise additional funds to pursue other development activities related to additional product candidates.

Our future capital requirements will depend on many factors, including:

the cost, progress, results of the proof-of-concept Phase 2 clinical trials of FS118 and any later-stage clinical trials for this product candidate;
the cost, progress, and results of the Phase 1 clinical trials of FS222, FS120, and SB 11285 and any later-stage clinical trials for these product candidates;

51


 

the scope, progress, results and costs of preclinical development, laboratory testing and clinical trials for any future product candidate;
the number of potential new product candidates we identify and decides to develop;
the cost of manufacturing drug supply for the clinical trials of our product candidates;
the time and costs involved in obtaining regulatory approval for our product candidates and any delays we may encounter as a result of evolving regulatory requirements or adverse clinical trial results with respect to any of our product candidates;
the costs involved in growing our organization to the size and expertise needed to allow for the research, development and potential commercialization of our current or any future product candidates;
fulfilling obligations under our existing collaboration agreements and the entry into new collaboration agreements;
the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims, including any claims by third parties that we are infringing upon their intellectual property rights;
the cost of commercialization activities and costs involved in the creation of an effective sales, marketing and healthcare compliance organization for any product candidates we develop, if approved;
the potential additional expenses attributable to adjusting our development plans (including any supply related matters) to the COVID-19 pandemic;
the potential additional expenses attributable to adjusting our development plans (including any supply related matters) to the Ukraine conflict;
the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval; and
the costs of operating as a public company.

Until we can generate sufficient product revenue to finance our cash requirements, which we may never do, we expect to finance our future cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing or distribution arrangements. Disruptions in the financial markets in general and the COVID-19 pandemic may make equity and debt financing more difficult to obtain and may have a material adverse effect on our ability to meet our fundraising needs.

Our ability to raise additional funds will depend on financial, economic and market conditions and other factors, over which we may have no or limited control. If adequate funds are not available on commercially acceptable terms when needed, we may be forced to delay, reduce or terminate the development or commercialization of all or part of our research programs product candidates or we may be unable to take advantage of future business opportunities.

Raising additional capital may cause dilution to our existing shareholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our operations with our existing cash and cash equivalents, including revenue from our collaborations. In order to further advance development of our product candidates, discover additional product candidates and pursue our other business objectives, however, we will need to seek additional funds.

We cannot guarantee that future financing will be available in sufficient amounts or on commercially reasonable terms, if at all. To the extent that we raise additional capital by issuing equity securities, our existing shareholders’ ownership may experience substantial dilution, and the terms of these securities may include liquidation or other preferences that adversely affect our rights as a shareholder. Equity and debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as redeeming our shares, making investments, incurring additional debt, making capital expenditures or declaring dividends.

52


 

The incurrence of indebtedness could result in increased fixed payment obligations and we may be required to agree to certain restrictive covenants therein, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely affect our ability to conduct our business.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue one or more of our research or development programs or the commercialization of any of our product candidates, if approved, or be unable to expand our operations or otherwise capitalize on our business opportunities, as desired, which could materially affect our business, financial condition and results of operations.

We have identified conditions and events that raise substantial doubt about our ability to continue as a going concern, which may hinder our ability to obtain future financing.

We expect our costs and expenses to increase as we continue to develop our product candidates and progress our current clinical programs and costs associated with being a public company.

We had cash and cash equivalents of $78.5 million as of December 31, 2021, which we believe that should be sufficient to fund our operating plan into February 2023. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Pursuant to the requirements of Accounting Standards Codification (ASC) 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, and as a result of our financial condition and other factors described herein, there is substantial doubt about our ability to continue as a going concern for a period of at least twelve months from the date of the financial statements. Our ability to continue as a going concern will depend on our ability to obtain additional funding, as to which no assurances can be given. Our future success depends on our ability to raise capital and/or execute our current operating plan. However, we cannot be certain that these initiatives or raising additional capital, whether through selling additional debt or equity securities or obtaining a line of credit or other loan, will be available to us or, if available, will be on terms acceptable to us. If we issue additional securities to raise funds, these securities may have rights, preferences, or privileges senior to those of our common stock, and our current shareholders may experience dilution. If we are unable to obtain funds when needed or on acceptable terms, we may be required to curtail our current development programs, cut operating costs, forego future development and other opportunities or even terminate our operations, which may involve seeking bankruptcy protection.

We may be subject to adverse legislative or regulatory tax changes that could negatively impact our financial condition.

The rules dealing with U.S. federal, state and local income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. Changes to tax laws (which changes may have retroactive application) could adversely affect our stockholders or us. In recent years, many such changes have been made and changes are likely to continue to occur in the future. We cannot predict whether, when, in what form, or with what effective dates, tax laws, regulations and rulings may be enacted, promulgated or decided, which could result in an increase in our, or our stockholders’, tax liability or require changes in the manner in which we operate in order to minimize increases in our tax liability.

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.

Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change net operating losses ("NOLs") and certain other tax assets (tax attributes) to offset future taxable income. In general, an ownership change occurs if the aggregate stock ownership of certain stockholders increases by more than 50 percentage points over such stockholders' lowest percentage ownership during the testing period (generally three years). We have experienced such ownership changes both in October 2018, November 2020, and May 2021; we may also experience an ownership change in the future as a result of shifts in our stock ownership, some of which are outside our control. The Company underwent a 382 study in 2021 and, as a result to the three afformentioned ownership changes, were limited in their NOL realization. As of December 31, 2021, we had federal and state net operating loss carryforwards of approximately $80.9 million and $79.8 million, respectively, after applying the 382 limitation to the NOL carried forward from 2020. In addition, pursuant to the Tax Cuts and Jobs Act, we may not use U.S. federal net operating loss carryforwards to reduce our taxable income in any year by more than 80%, and we may not carry back any net operating losses to prior years. These new rules apply regardless of the occurrence of an ownership change.

Risks Related to Development and Commercialization

If we are unable to advance our current or future product candidates through clinical trials, obtain marketing approval and ultimately commercialize any product candidates we develop, or if we experience significant delays in doing so, our business will be materially harmed.

We are early in our product candidate development efforts and have four product candidates in clinical development, each of which is still in early-stage clinical trials. We have invested substantially all of our efforts and financial resources in the development of our proprietary mAb2 technology, identification of targets and preclinical development of our product candidates.

Our ability to generate product revenues, which we do not expect will occur for several years, if ever, will depend heavily on the successful development and eventual commercialization of the product candidates we develop, which may never occur. Our current product candidates, and any future product candidates we develop, will require additional preclinical and clinical development, management of clinical, preclinical and manufacturing activities, marketing approval in the United States and other jurisdictions, demonstrating cost effectiveness to pricing and reimbursement authorities in various jurisdictions, obtaining and securing sufficient manufacturing supply for both clinical development and commercial production, building of a commercial organization, and substantial investment and significant marketing efforts before we generate any revenues from any future product sales. Moreover, the success of our current and future product candidates will depend on several factors, including the following:

successful and timely completion of preclinical studies, including in vivo animal studies if necessary, and human clinical trials;
sufficiency of our financial and other resources to complete the necessary preclinical studies and clinical trials;
receiving regulatory approvals or authorizations for conducting our planned clinical trials or future clinical trials;
initiation and successful patient enrollment in and completion of clinical trials on a timely basis;
safety, tolerability and efficacy profiles that are satisfactory to the FDA, the EMA, the MHRA or any other comparable foreign regulatory authority for a product to receive marketing approval;
timely receipt of marketing approvals for our product candidates from applicable regulatory authorities;
the extent of any required post-marketing approval commitments made to applicable regulatory authorities;
establishing and scaling up, either alone or with third-party manufacturers, manufacturing capabilities of clinical supply for our clinical trials and subsequently for commercial manufacturing, if any product candidates are approved;
obtaining and maintaining patent and trade secret protection or regulatory exclusivity for our product candidates, the latter only if they receive marketing approval, both in the United States and internationally;
successfully scaling a sales and marketing organization and launching commercial sales of our product candidates, if approved;
acceptance of our product candidates’ benefits and uses, if approved, by patients, the medical community and third-party payors;
maintaining a continued acceptable safety profile of our product candidates following marketing approval and commercial launch;
effectively competing with companies developing and commercializing other therapies in the same indications targeted by our product candidates;
obtaining and maintaining healthcare coverage and adequate reimbursement from third-party payors for any approved products; and
enforcing and defending intellectual property rights and claims.

54


 

If we are not successful with respect to one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize any product candidates we develop, which would materially harm our business. If we do not receive marketing approvals for our current and future product candidates, we may not be able to continue our operations.

All of our product candidates are in early clinical development. Clinical trials are difficult to design and implement, and they involve a lengthy and expensive process with uncertain outcomes. We may experience delays in completing, or ultimately be unable to complete, the development and commercialization of our current and future product candidates.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process and our future clinical trial results may not be successful.

To date, we have not completed any clinical trials required for the approval of any of our product candidates. Although FS118 is currently being evaluated in Phase 2 proof-of-concept trials and FS222, FS120, and SB 11285 are currently being evaluated in Phase 1 trials, we may experience delays in our ongoing clinical trials and we do not know whether planned clinical trials will begin on time, need to be redesigned, enroll study subjects on time, have sufficient drug supply of our product candidates in order to be completed timely or be completed on schedule, if at all. We may also experience numerous unforeseen events during our clinical trials that could delay or prevent our ability to complete the trials successfully and ultimately to receive marketing approval or to commercialize the product candidates we are developing, including:

delays in or failure to obtain regulatory approval or clearance to commence a clinical trial or inability to comply with conditions imposed by a regulatory authority regarding the scope or design of a clinical trial;
delays or failure in reaching agreement with the FDA, the EMA, the MHRA, or a comparable foreign regulatory authority on appropriate clinical trial designs;
delays in or failure to reach agreement on acceptable terms with prospective contract research organizations (“CROs”), and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
inability, delays or failure in identifying and maintaining a sufficient number of clinical trial sites, many of which may already be engaged in other clinical research programs;
delays in or failure to obtain ethics committee/institutional review board (“EC/IRB”) approval at each site participating in the trial;
delays in or failure to recruit a sufficient number of suitable subjects to participate in a trial;
failure to have participants complete a trial or return for post-treatment follow-up, or other inability to monitor patients adequately during or after treatment;
clinical sites or clinical investigators deviating from trial protocol or dropping out of a trial;
delays in adding new clinical trial sites;
failure to manufacture sufficient quantities of a product candidate for use in clinical trials in a timely manner;
delay or failure in developing and validating companion diagnostics, if they are deemed necessary, on a timely basis;
safety or tolerability concerns that could cause us or our collaborators, as applicable, to suspend or terminate a trial if we or our collaborators find that the participants are being exposed to unacceptable health risks;
changes in regulatory requirements, policies and guidelines;
failure of our third-party research contractors, including clinical sites and investigators, to comply with regulatory requirements applicable to the trial, including GCPs, or to meet their contractual obligations to us in a timely manner, or at all;
delays in establishing the appropriate dosage levels for a particular product candidate through clinical trials;
the quality or stability of the product candidate falling below acceptable standards; and

55


 

business interruptions resulting from pandemics, such as the ongoing COVID-19 pandemic, or geo-political actions, including war and terrorism, or natural disasters including earthquakes, typhoons, floods and fires.

We could encounter delays if we elect to suspend or terminate a clinical trial, or if a trial is suspended or terminated by the EC/IRBs of the institutions in which such trials are being conducted, or by the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities, or if a trial is recommended for suspension or termination by the Safety Review Committee (“SRC”), Data Review Committee (“DRC”), or Data Safety Monitoring Board (“DSMB”), for such trial. Any such authorities may impose such a suspension or termination of ongoing human subjects research due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, including those relating to the class to which our product candidates belong, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If we experience delays in the completion of, or if we terminate, any clinical trial of a product candidate, the commercial prospects of our product candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed or may become impossible. In addition, any delays in completing clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence future product sales and generate revenues.

Moreover, if we make changes to our product candidates, we may need to conduct additional scientific studies to bridge our modified product candidates to earlier versions, which could delay our clinical development plans or future marketing approval for our product candidates. Significant clinical trial delays could also allow our competitors to bring products to market before we do or shorten any periods during which we have the exclusive right to commercialize our product candidates, if approved for marketing, and impair our ability to commercialize any such product candidates.

Any of these occurrences may harm our business, reputation, financial condition and results of operations significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval for our product candidates or result in the cessation of development of our product candidates.

Our clinical trials may fail to demonstrate adequately the safety and efficacy of any of our product candidates, which would prevent or delay regulatory approval and commercialization.

We currently have no products approved for sale and cannot guarantee that we will ever have marketable products. To obtain the requisite regulatory approvals to market and sell any of our product candidates, including FS118, FS222, FS120, SB 11285, and any other future product candidates, we must demonstrate through extensive preclinical studies and clinical trials that our products are safe and effective in humans for their intended use or uses. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process and our future clinical trial results may not be successful. Further, the process of obtaining regulatory approval to market therapeutic products like our product candidates is expensive, often takes many years following the commencement of clinical trials and can vary substantially based upon the type, complexity and novelty of the product candidates involved, as well as the target indications, patient population and regulatory agency considering the product’s marketing application. Prior to obtaining approval to commercialize a product candidate in the United States or abroad, we or our potential future collaborators must demonstrate with substantial evidence from adequate and well-controlled clinical trials, and to the satisfaction of the FDA, the EMA the MHRA, or other comparable foreign regulatory authorities, that such product candidates are safe and effective for their intended uses.

Clinical trials that we conduct may not demonstrate the efficacy and safety necessary to obtain regulatory approval to market our product candidates. In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the clinical trial protocols and the rate of dropout among clinical trial participants. If the results of our ongoing or future clinical trials are inconclusive with respect to the efficacy of our product candidates, if we do not meet the clinical endpoints with statistical and clinically meaningful significance, or if there are safety concerns associated with our product candidates, we may be delayed in obtaining marketing approval, if at all.

56


 

Even if the trials are successfully completed, clinical data are often susceptible to varying interpretations and analyses, and we cannot guarantee that the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities will interpret the results as we do, and more trials could be required before we submit a product candidate for marketing approval. We cannot guarantee that the FDA, the EMA or other comparable foreign regulatory authorities will view our product candidates as being effective and having a favorable benefit-risk profile even if positive results are observed in clinical trials. To the extent that the results of the trials are not satisfactory to the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities for support of a marketing application, approval of our product candidates may be significantly delayed, or we may be required to expend significant additional resources, which may not be available to us, to conduct additional trials in support of potential approval of our product candidates.

The results of preclinical studies and early-stage clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Initial success in our ongoing clinical trials may not be indicative of results obtained when these trials are completed or in later-stage trials.

Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. Furthermore, there can be no assurance that any of our clinical trials will ultimately be successful or support further clinical development of any of our product candidates. There is a high failure rate for drugs proceeding through clinical trials. Many companies in the biotechnology and pharmaceutical industries have suffered significant setbacks in late-stage clinical trials after achieving positive results in early-stage development and we cannot be certain that we will not face similar setbacks. These setbacks have been caused by, among other things, preclinical findings made while clinical trials were underway, or safety or efficacy observations made in preclinical studies and clinical trials, including previously unreported adverse events. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses and many companies that believed their product candidates performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain regulatory authority approval. Any such setbacks in our clinical development could have a material adverse effect on our business, financial condition and results of operations.

Additionally, some of the clinical trials we conduct may include open-label trials conducted at a limited number of clinical sites on a limited number of patients. An “open-label” clinical trial is one where both the patient and investigator know whether the patient is receiving the investigational product candidate or either an existing approved product or placebo. Most typically, open-label clinical trials test only the investigational product candidate and sometimes may do so at different dose levels. Open-label clinical trials are subject to various limitations that may exaggerate any therapeutic effect as patients in open-label clinical trials are aware when they are receiving treatment. Open-label clinical trials may be subject to a “patient bias” where patients perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. Moreover, patients selected for early-stage clinical trials often include the most severe sufferers and their symptoms may have been bound to improve notwithstanding the new treatment. In addition, open-label clinical trials may be subject to an “investigator bias” where those assessing and reviewing the physiological outcomes of the clinical trials are aware of which patients have received treatment and may interpret the information of the treated group more favorably given this knowledge.

Interim, topline and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publish interim, topline or preliminary data from our clinical trials. Preliminary and interim data from our clinical trials may change as more patient data become available. Preliminary or interim data from our clinical trials are not necessarily predictive of final results. Preliminary and interim data are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues, more patient data become available, and we issue our final clinical trial report. Interim, topline and preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, preliminary, topline and interim data should be viewed with caution until the final data are available. Material adverse changes in the final data compared to the interim data could significantly harm our business prospects.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or therapeutic product, if any,

57


 

and us in general. In addition, the information we choose to publicly disclose regarding a particular preclinical study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular therapeutic product, if any, product candidate or our business. If the preliminary and interim data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Our product candidates may have serious adverse, undesirable or unacceptable side effects that may delay or prevent marketing approval. If such side effects are identified during the development of our product candidates or following approval, we may need to abandon development of such product candidates, the commercial profile of any approved label may be limited, or we may be subject to other significant negative consequences following marketing approval.

Undesirable side effects that may be caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label should the candidate be approved for marketing or the delay or denial of regulatory approval by the FDA, the EMA or other comparable foreign regulatory authorities. While the data collected on our product candidates in our preclinical studies, and the early clinical trial experience with FS118, FS222, FS120, and SB 11285 to date, suggest that the candidates have generally been well-tolerated from a risk-benefit perspective, the results from future preclinical studies and clinical trials, including of our other product candidates, may not support this conclusion.

The results of our ongoing proof-of-concept Phase 2 clinical trials of FS118 and Phase 1 trials for FS222, FS120, and SB 11285, and future clinical trials of these and other product candidates may show that our product candidates cause undesirable or unacceptable side effects or even death. In such an event, our trials could be suspended or terminated and the FDA, the EMA or other comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. The product-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Further, because the majority of our current product candidates are based on our modular antibody technology platform and our mAb2 technology, any adverse safety or efficacy findings related to any mAb2 product candidate or preclinical program may adversely impact the viability of our other mAb2 product candidates or preclinical programs. Any of these occurrences may harm our business, reputation, financial condition and results of operations significantly.

Additionally, if any of our product candidates receives marketing approval and we or others later identify undesirable or unacceptable side effects caused by such a product, a number of potentially significant negative consequences could result, including:

regulatory authorities may withdraw approvals of such product and require our approved product to be taken off the market, through a recall or other action;
regulatory authorities may require the addition of labeling statements or specific warnings, such as a “black box” warning or a contraindication, to the product’s prescribing information, or require field alerts to be sent to physicians and pharmacies;
regulatory authorities may require a medication guide explaining the risks of such side effects to be distributed to patients, or that we are to implement a risk evaluation and mitigation strategy to ensure that the benefits of the product outweigh its risks (such as through a REMS in the United States that may include a restricted distribution program or educational programs for prescribers);
we may be required to change the way the product is administered;
we may be required to conduct additional clinical trials or costly post-marketing testing and surveillance to monitor the safety of the product;
we may be subject to limitations on how we may promote the product;
sales of the product may decrease significantly;
we may be subject to litigation or product liability claims; and

58


 

our reputation may suffer.

Any of these events could prevent us, our collaborators or our potential future partners from achieving or maintaining market acceptance of the affected product or could substantially increase commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenue from the sale of our mAb2 product candidates, if approved.

We may find it difficult to enroll subjects in our clinical trials, which could delay or prevent us from proceeding with clinical trials of our product candidates.

Identifying and qualifying study subjects to participate in clinical trials of our product candidates is critical to our success. The timing of our clinical trials depends on our ability to recruit eligible subjects to participate as well as the completion of required follow-up evaluations. Patients and healthy volunteers may be unwilling to participate in our clinical trials because of negative publicity from adverse events related to novel therapeutic approaches, competitive clinical trials for similar patient populations, the existence of current treatments or for other reasons including due to concerns posed by the COVID-19 pandemic. Enrollment risks are heightened with respect to indications that we may target in the future that may be rare or orphan diseases, which may limit the pool of patients that may be enrolled in our planned clinical trials. Any delays related to subject enrollment could result in increased costs, delays in advancing our product candidates, delays in testing the effectiveness of our product candidates or termination of the clinical trials altogether. We may not be able to identify, recruit and enroll a sufficient number of subjects, or those with the required or desired characteristics, to complete our clinical trials in a timely manner. Enrollment and trial completion is affected by many factors, including the:

size and nature of the patient population and process for identifying potential study subjects;
proximity and availability of clinical trial sites for prospective participants;
the extent of we and our collaborators’ efforts to facilitate timely enrollment in clinical trials;
eligibility and exclusion criteria for the trial;
design of the clinical trial;
safety profile, to date, of the product candidate under study;
perceived risks and benefits of the product candidate under study;
perceived risks and benefits of our approach to treatment of diseases;
competition with other companies for clinical sites and qualified clinical investigators;
severity of the disease under investigation;
degree of progression of the subject’s disease at the time of enrollment;
ability to obtain and maintain the study subject’s informed consent;
risk that enrolled subjects will drop out before completion of the trial;
competing clinical trials and clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new products that may be approved for the indications we are investigating;
patient referral practices of physicians; and
ability to adequately monitor subjects during and after investigational treatment.

We face significant competition for our drug discovery and development efforts, and if we do not compete effectively, our commercial opportunities will be reduced or eliminated.

We compete in the segments of the biotechnology, pharmaceutical and other related markets that develop immuno-oncology therapies, and the market for biopharmaceutical products is highly competitive. Our competitors include many established pharmaceutical companies, biotechnology companies, universities and other research or commercial institutions, many of which have substantially greater financial, research and development resources than us. Large pharmaceutical companies, in

59


 

particular, have extensive experience in clinical testing, recruiting patients, obtaining regulatory approvals, manufacturing and marketing pharmaceutical products. Smaller and early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, the development of our product candidates. The fields in which we operate are characterized by rapid technological change and innovation.

There are many other companies that have commercialized and/or are developing immuno-oncology therapies for cancer including large biotechnology and pharmaceutical companies, such as AstraZeneca, BMS, Eli Lilly, MSD, Merck KGaA , Darmstadt, Germany (“EMD Serono”), Novartis, Pfizer, Genentech, Inc. (“Genentech”), a subsidiary of the F. Hoffmann-La Roche AG Group (“Roche”) and Sanofi. A number of companies, not limited to those above, are attempting to combine immuno-oncology antibody therapies in order to modulate two cancer pathways simultaneously. Others have developed bispecific antibodies or bispecific fusion proteins in order to leverage the effect of a combination of single-target traditional monoclonal antibodies, which we refer to as traditional antibodies, in a single molecule.

 

With respect to our mAb2 bispecific antibody pipeline, we are aware of several competitors using other technology methods to create bispecific antibodies to treat a variety of cancer types, including, but not limited to Genmab A/S, Inhibrx, MacroGenics, Merus, Pieris Pharmaceuticals, Hoffmann-LaRoche, Shattuck Labs, and Xencor, Inc.

 

With respect to our lead mAb2 product candidate, FS118, we are aware of other competing molecules targeting LAG-3 and PD-1/PD-L1 receptors. Companies pursuing a bispecific molecule directed against LAG-3 and PD-1/PD-L1 in different phases of clinical development include but are not limited to Epimab, Hoffmann-La Roche, I-mab/ABLBio, Innovent, and MacroGenics. We are also aware of other companies pursuing a combination of two traditional antibodies in different phases of clinical development, with the first one targeting PD-1/PD-L1, and the second one targeting LAG-3, which include but are not limited to: BMS, C.H. Boehringer Sohn AG & Co. KG, Nanjing Leads Biolabs/Beigene, and MSD, Novartis, and Regeneron.

 

With respect to our second mAb2 product candidate, FS222, we are aware of other companies pursuing bispecific antibodies targeting PD-L1 and CD137 in clinical development, which include but are not limited to: ABL Bio, Antegene, Biotheus, Genmab/BioNTech SE, Inhibrx/Elpiscience, Merus, Numab Therapeutics AG/CStone Pharmaceuticals, Pieris/Servier, and Qilu Pharmaceutical Co.. We are also aware of other companies that are pursuing a combination of two traditional antibodies in clinical development, with the first one targeting PD-1/PD-L1, and the second one targeting CD137, which include but are not limited to: Adagene, BMS, Eucure Biopharma, Hoffmann-La Roche, Lyvgen Biopharma (Suzhou)/MSD and, Pfizer.

 

With respect to our third mAb2 product candidate, FS120, we are aware of other companies pursuing bispecific antibodies targeting OX40 and CD137, which include but are not limited to Aptevo Therapeutics. We are also aware that Pfizer has ongoing clinical studies evaluating a combination of CD137 plus OX40 traditional antibodies.

 

With respect to our fourth product candidate, SB 11285, we are aware of other companies pursuing a second generation, IV administered STING agonist, in clinical development. These companies include but are not limited to: GSK, Millennium Therapeutics/ Takeda and Stingthera, Inc. Additionally, several other companies are developing a first generation and/or an intratumorally administered STING agonist in the clinic.

We anticipate that we will continue to face increasing competition as new treatments enter the market and advanced technologies become available. There can be no assurance that our competitors are not currently developing, or will not in the future develop, products that are equally or more effective or are safer or are more economically attractive than any of our current or future product candidates, or platforms and technology that are superior to our modular antibody technology platform and our mAb2 technology. Competing products or technology platforms may gain faster or greater approval or market acceptance than our products, if any, or modular antibody technology platform and medical advances or rapid technological development by competitors may result in our product candidates or modular antibody technology platform becoming non-competitive or obsolete before we are able to recover our research and development and commercialization expenses. If we, our product candidates or our modular antibody technology platform do not compete effectively, it may have a material adverse effect on our business, financial condition, and results of operations.

The regulatory approval processes of the FDA, the EMA, the MHRA, and other comparable foreign regulatory authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be substantially harmed.

The time required to obtain marketing approval for a novel therapeutic product from the FDA, the EMA, the MHRA, and other comparable foreign regulatory authorities is unpredictable but typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, laws or regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. We have not obtained regulatory approval for commercialization of any product candidate and it is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever obtain that approval.

Our product candidates could fail to receive regulatory approval for many reasons, including the following:

The FDA, the EMA, the MHRA, or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials;
we may be unable to demonstrate to the satisfaction of the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities that a mAb2 product candidate is safe, pure and potent or effective for its proposed indication(s) or that a small-molecule drug product candidate is safe and effective for its proposed indication(s);
the results of clinical trials may not meet the level of statistical significance required by the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities in order to support approval;
we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks;
the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical trials;
the data collected from clinical trials of our product candidates may not be sufficient to support the submission of a BLA or NDA, to the FDA or other equivalent marketing authorization application submissions to obtain regulatory approval in the United States, the European Union, or elsewhere;
upon review of our clinical trial sites and data, the FDA, the EMA, the MHRA, or comparable foreign regulatory authorities may find our record keeping or the record keeping of our clinical trial sites or investigators to be inadequate;
the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities may find deficiencies with or fail to approve the manufacturing processes or facilities of third-party manufacturers with which we contract for clinical and commercial supplies; and
the approval policies or regulations of the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities or the laws they enforce may significantly change in a manner rendering our clinical data insufficient for approval.

This lengthy approval process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval to market any of our product candidates, which would significantly harm our business, financial condition and results of operations. The FDA, the EMA, the MHRA, and other comparable foreign regulatory authorities have substantial discretion in the approval process and determining when or whether to grant regulatory approval will be obtained for any of our product candidates, and whether to impose any conditions on such marketing approvals as described below. Even if we believe the data collected from clinical trials of our product candidates are promising, such data may not be sufficient to support approval by the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities.

In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates for fewer or more limited indications than we request, if any, they may grant approval contingent on the performance of costly post-marketing clinical trials, or they may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate or with restrictive risk mitigation measures or warning language or contraindications that make the approved product more difficult or costly to commercialize. Any of the foregoing scenarios could materially harm the commercial prospects for our product candidates.

If we are required by the FDA to obtain approval of a companion diagnostic in connection with approval of a product candidate, and we do not obtain or face delays in obtaining FDA approval of a diagnostic device, we will not be able to commercialize the product candidate and our ability to generate revenue will be materially impaired.

According to current FDA policies, if the FDA determines that a companion diagnostic device is essential to the safe and effective use of a novel therapeutic product in an intent to treat indication, the FDA will not approve the therapeutic product or new therapeutic product indication if the companion diagnostic is not also approved or cleared for that indication. Under the U.S. Federal Food, Drug, and Cosmetic Act, companion diagnostics are regulated as medical devices, and the FDA requires companion diagnostics intended to select the patients who likely will respond to cancer treatment to receive Premarket Approval (“PMA”) before being commercially distributed. The PMA application process, including the gathering of analytical and prospective clinical data and the submission to and review by the FDA, is rigorous and requires the applicant to provide the FDA with reasonable assurance of the device’s safety and effectiveness and information about the device and its components regarding, among other things, device design, performance, good manufacturing practices, and labeling. A PMA is not guaranteed and may take considerable time, and the FDA may ultimately respond to a PMA submission with a “not approvable” determination based on deficiencies in the application and require additional clinical trial or other data that may be expensive and time-consuming to generate and that can substantially delay approval. As a result, if we are required by the FDA to obtain approval of a companion diagnostic for a therapeutic product candidate, and we do not obtain or there are delays in obtaining FDA approval of such a diagnostic device, we may not be able to commercialize the product candidate on a timely basis or at all and our ability to generate revenue will be materially impaired.

Any product candidate for which we obtain marketing approval will be subject to extensive post-marketing regulatory requirements, which may result in significant additional expense, and could be subject to post-marketing restrictions or withdrawal from the market, and we or our partners may be subject to penalties for any failure to comply with regulatory requirements or if problems are discovered with a product after approval.

Our therapeutic product candidates, if approved, could be subject to labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply with ongoing regulatory requirements or experiences unanticipated problems with any such approved prescription drug or biological products.

If the FDA, the EMA, the MHRA, or other comparable foreign regulatory authority approves any of our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the therapeutic product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, establishment registration, as well as continued compliance with cGMP by all facilities involved in the production of the approved therapeutic product and with compliance with GCP by all collaborators in any clinical trials that we may conduct post-approval, each of which may result in significant expense. In addition, any regulatory approvals that we receive for our product candidates may also be subject to limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. The FDA, as well as its foreign regulatory counterparts, also have significant post-market authority, including the authority to require labeling changes based on new safety information.

Moreover, the FDA strictly regulates the promotional claims that may be made about prescription drug and biological products. In particular, a product may not be promoted for off-label uses that are not approved by the FDA as reflected in the product’s approved prescribing information and other FDA-approved product labeling. However, companies may share truthful and not misleading information that is otherwise consistent with a product’s FDA approved labeling. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses for prescription medical products. Further, if there are any modifications to the biologic, including changes in indications, labeling or manufacturing processes or facilities, the applicant may be required to submit and obtain FDA approval of a new BLA/NDA or BLA/NDA supplement.

If there are changes in the application of legislation, regulations or regulatory policies, or if problems are discovered with a product or our manufacture of a product, or if we or one of our distributors, licensees or co-marketers fails to comply with regulatory requirements, regulatory authorities could take various actions against the therapeutic product or against us as the product’s sponsor. These include imposing fines on us, imposing restrictions on the product or its manufacture and requiring a recall or other removal of the product from the market. The regulators could also suspend or withdraw our marketing authorizations, require us to conduct additional clinical trials or to submit additional applications for marketing authorization,

62


 

or require safety updates to or otherwise change the product labeling for an approved therapeutic product. If any of these events occurs, our ability to sell such product may be impaired, and We may incur substantial additional expense to comply with regulatory requirements, which could materially adversely affect our business, financial condition and results of operations.

We may become exposed to costly and damaging liability claims, either when testing our product candidates in the clinic or at the commercial stage, and our product liability insurance may not cover all damages from such claims.

We are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manufacturing, marketing and use of biopharmaceutical products. Currently, we have no products that have been approved for commercial sale; however, the current and future use of product candidates by us and our collaborators in clinical trials, and the potential sale of any approved products in the future, may expose us to liability claims. These claims might be made by patients who use the product, healthcare providers, pharmaceutical companies, our collaborators or others selling such products. Any claims against us, regardless of their merit, could be difficult and costly to defend and could materially adversely affect the market for our product candidates or any prospects for commercialization of our product candidates. Although the clinical trial process is designed to identify and assess potential side effects, it is always possible that a product, even after regulatory approval, may exhibit unforeseen side effects. If any of our product candidates were to cause adverse side effects during clinical trials or after approval of the product candidate, we may be exposed to substantial liabilities. Physicians and patients may not comply with any warnings that identify known potential adverse effects and patients who should not use our product candidates. Regardless of the merits or eventual outcome, liability claims may result in:

decreased demand for our products due to negative public perception;
injury to our reputation;
withdrawal of clinical trial participants or difficulties in recruiting new trial participants;
initiation of investigations by regulators;
costs to defend or settle the related litigation;
a diversion of management’s time and our resources;
substantial monetary awards to trial participants or patients;
product recalls, withdrawals or labeling, marketing or promotional restrictions;
loss of revenues from product sales; and
the inability to commercialize any of our product candidates, if approved.

Although we believe we maintain adequate product liability insurance for our product candidates, it is possible that our liabilities could exceed our insurance coverage. We intend to expand our insurance coverage to include the sale of commercial products if we obtain marketing approval for any of our product candidates. However, we may not be able to maintain insurance coverage at a reasonable cost or obtain insurance coverage that will be adequate to satisfy any liability that may arise. If a successful product liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, our assets may not be sufficient to cover such claims and our business operations could be impaired.

Should any of the events described above occur, this could have a material adverse effect on our business, financial condition and results of operations.

Due to our limited resources and access to capital, we must, and have in the past decided to, prioritize development of certain product candidates over other potential product candidates. These decisions may prove to have been wrong and may adversely affect our ability to develop our own programs, our attractiveness as a commercial partner and may ultimately have an impact on our commercial success.

Because we have limited resources and access to capital to fund our operations, we must decide which product candidates to pursue and the amount of resources to allocate to each. Our decisions concerning the allocation of research, collaboration, management and financial resources toward particular mAb2 bispecific antibodies, product candidates or therapeutic areas

63


 

may not lead to the development of viable commercial products and may divert resources away from better opportunities. Similarly, our decisions to delay, terminate or collaborate with third parties in respect of certain product development programs may also prove not to be optimal and could cause us to miss valuable opportunities. If we make incorrect determinations regarding the market potential of our product candidates or misreads trends in the biopharmaceutical industry our business, financial condition and results of operations could be materially adversely affected.

We may seek orphan drug designation for product candidates we develop, and we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation, including the potential for market exclusivity if a designed product candidate is ultimately approved.

As part of our business strategy, we may seek orphan drug designation for any product candidates we develop, and we may be unsuccessful in securing such a designation. Regulatory authorities in some jurisdictions, including the United States and the European Union, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act in the United States, the FDA may designate a drug or a biological product as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States. In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards certain clinical trial costs, tax advantages and user-fee waivers.

Similarly, in Europe, the European Commission grants orphan designation after receiving the opinion of the EMA Committee for Orphan Medicinal Products on an orphan designation application. Orphan designation is intended to promote the development of drugs that are intended for the diagnosis, prevention or treatment of life-threatening or chronically debilitating conditions affecting not more than 5 in 10,000 persons in the European Union and for which no satisfactory method of diagnosis, prevention, or treatment has been authorized (or the product would be a significant benefit to those affected). Additionally, designation is granted for drugs intended for the diagnosis, prevention, or treatment of a life-threatening, seriously debilitating or serious and chronic condition and when, without incentives, it is unlikely that sales of the drug in the European Union would be sufficient to justify the necessary investment in developing the drug. In the European Union, orphan designation entitles a party to a number of incentives, such as protocol assistance and scientific advice specifically for designated orphan medicines, and potential fee reductions depending on the status of the sponsor.

Generally, in the United States, if a drug or biologic with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the drug is entitled to a period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same drug and the same orphan indication for that time period, except in limited circumstances. The applicable period is seven years in the United States. In addition, there is a potential to receive a six-month extension of orphan exclusivity if certain pediatric studies are conducted and the results are reported to the FDA in response to a Written Request for such studies under the Best Pharmaceuticals for Children Act.

In Europe, an approved orphan medicinal product is entitled to ten years of market exclusivity in all European Union member states. However, marketing authorization may be granted to a similar medicinal product with the same orphan indication during the ten-year period with the consent of the marketing authorization holder for the original orphan medicinal product or if the manufacturer of the original orphan medicinal product is unable to supply sufficient quantities of such product. Marketing authorization may also be granted to a similar medicinal product with the same orphan indication if the similar product is established to be safer, more effective or otherwise clinically superior to the original orphan medicinal product. After five years, an EU member state can request that the period of market exclusivity be reduced to six years if it can be demonstrated that the criteria for orphan designation no longer apply and the medicine is sufficiently profitable. The period of market exclusivity may be extended for an additional two years for medicines that have also complied with an agreed PIP.

Similarly, even if we obtain orphan drug exclusivity for a product candidate that is approved for marketing in the United States, such exclusivity may not effectively protect the product candidate from competition because different therapies can be approved for the same condition and the same therapies can be approved for different conditions but used off-label. Even after an orphan drug is approved, the FDA can subsequently approve the later drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. In addition, a designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. Moreover, orphan drug exclusive marketing rights in

64


 

the United States may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition.

Orphan drug designation neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. While we may seek orphan drug designation for applicable indications for our current and any future product candidates, we may never receive such designations.

Accordingly, even if we do receive such designations in the United States and/or in Europe, there is no guarantee that we will enjoy the benefits of those designations.

Our approach to the discovery and development of our therapeutic treatments is based on novel technologies that are unproven and may not result in marketable products.

We plan to develop a pipeline of mAb2 product candidates using our modular antibody technology platform. We believe that mAb2 product candidates identified with our modular antibody technology platform may offer an improved therapeutic approach by creating fully formed molecules using standard antibody production technology, thereby potentially improving the binding and biological response, and reducing any need for reassembly or other post-synthesis modifications.

However, we have not, nor to our knowledge has any other company, received regulatory approval for a therapeutic that uses tetravalent bispecific IgG1 antibody technology. We cannot be certain that our approach will lead to the development of approvable or marketable products. In addition, the FDA, the EMA, the MHRA, or other comparable foreign regulatory agencies may lack experience in evaluating the safety and efficacy of products based on our mAb2 technology, which could result in a longer than expected regulatory review process, increase our expected development costs and delay or prevent commercialization of our mAb2 product candidates.

We may not be successful in our efforts to utilize our modular antibody technology platform and mAb2 technology to build a pipeline of additional mAb2 product candidates. Failure to successfully identify, develop and commercialize additional products or mAb2 product candidates could impair our ability to grow.

Although a substantial amount of our efforts will continue to focus on the preclinical studies and clinical testing and potential approval of the mAb2 product candidates in our current pipeline, a key element of our long-term growth strategy is to identify, develop and market additional products and mAb2 product candidates. Because we have limited financial and managerial resources, continuing to utilize our modular antibody technology platform and our mAb2 technology to generate mAb2 bispecific antibodies and identify mAb2 product candidates with certain advantages, such as safety and potency, beyond what would be achieved with a combination of two traditional antibodies or bispecific antibodies, will require substantial additional technical, financial and human resources, whether or not any mAb2 product candidates are ultimately identified. Our modular antibody technology platform may fail to generate mAb2 bispecific antibodies that are suitable for further development, and we may fail to correctly identify future mAb2 product candidates that have the potential to become successful products. We will need to continue to invest in improving and expanding our modular antibody technology platform and our mAb2 technology, which will require scientific expertise and substantial resources.

We also have incorporated a novel technology of synthesizing cyclic dinucleotides for the generation of STING pathway targeting small-molecule drug product candidates, such as our current clinical candidate SB 11285. We cannot be certain that this approach will lead to the development of approvable or marketable products. In addition, the FDA, the EMA or other comparable foreign regulatory agencies may lack experience in evaluating the safety and efficacy of such products, which could result in a longer than expected regulatory review process, increase our expected development costs and delay or prevent commercialization of our product candidates. We may not be successful in our efforts to utilize our cyclic dinucleotide technology to build additional product candidates. Failure to successfully identify, develop and commercialize additional products or product candidates could impair our ability to grow.

All therapeutic product candidates are prone to risks of failure typical of biopharmaceutical product development, including the possibility that a product candidate may not be suitable for clinical development as a result of its harmful side effects, limited efficacy or other characteristics that indicate that it is unlikely to be a product that will receive approval by the FDA, the EMA and other comparable foreign regulatory authorities and achieve market acceptance. If we do not successfully

65


 

develop and commercialize our mAb2 biological product candidates or small-molecule STING agonist drug product candidates based upon our current platforms and technological approaches, we may not be able to obtain product or collaboration revenues in future periods, which would adversely affect our business, financial condition and results of operations.

Our product candidates that are successful in achieving marketing approval may face generic or biosimilar competition sooner than anticipated.

Even if we are successful in achieving regulatory approval to commercialize a product candidate for a specific indication ahead of our competitors, such an approved therapeutic candidate may face competition from generic or biosimilar products, as applicable.

In the United States, mAb2 product candidates are regulated by the FDA as biological products and we intend to seek approval for these therapeutic candidates pursuant to the BLA pathway. The BPCIA created an abbreviated pathway for the FDA approval of biosimilar biological products based on a previously licensed innovator, or reference, biological product. Under the BPCIA, an application for a biosimilar biological product cannot be approved by the FDA until 12 years after the original reference biological product was approved under a BLA. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty. While it is uncertain when such processes intended to implement BPCIA may be fully adopted by the FDA, any such processes could have a material adverse effect on the future commercial prospects for our product candidates.

We believe that any of our mAb2 product candidates approved as a biological product under a BLA should qualify for the 12-year period of exclusivity available to reference biological products. However, there is a risk that this exclusivity could be shortened due to Congressional action or otherwise, or that the FDA will not consider our therapeutic candidates to be reference biological products pursuant to its interpretation of the exclusivity provisions of the BPCIA, potentially creating the opportunity for follow-on biosimilar competition sooner than anticipated. Moreover, the extent to which a biosimilar product, once approved, will be substituted for any reference product in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing including whether a future competitor seeks an interchangeability designation for a biosimilar of a future approved biological products. Under the BPCIA as well as state pharmacy laws, only so-called “interchangeable” biosimilar products are considered substitutable for the reference biological product without the intervention of the healthcare provider who prescribed the original biological product. However, as with all prescribing decisions made in the context of a patient-provider relationship and a patient’s specific medical needs, healthcare providers are not restricted from prescribing biosimilar products in an off-label manner. In addition, a competitor could decide to forego the abbreviated approval pathway available for biosimilar products and to submit a full BLA for product licensure after completing its own preclinical studies and clinical trials. In such a situation, any exclusivity to which we may be eligible under the BPCIA would not prevent the competitor from marketing its biological product as soon as it is approved.

In Europe, the European Commission has granted marketing authorizations for several biosimilar products pursuant to a set of general and product class-specific guidelines for biosimilar approvals issued over the past few years. In addition, companies may be developing biosimilar products in other countries that could compete with our products, if approved.

If competitors are able to obtain marketing approval for biosimilars referencing an approved our mAb2 product candidates, if approved, our future products may become subject to competition from such biosimilars, whether or not they are designated as interchangeable, with the attendant competitive pressure and potential adverse consequences. Such competitive products may be able to immediately compete with us in each indication for which its product candidates may have received approval.

Further, our small-molecule drug product candidates such as SB 11285 are regulated by the FDA as drug products and would be subject to marketing approval by the FDA pursuant to an NDA submitted under Section 505(b)(1) of the FDCA. Even if we are successful in achieving regulatory approval to commercialize SB 11285 or a future drug product candidate, we may face competition from generic products earlier or more aggressively than anticipated, depending upon how well the future product performs in the United States prescription drug market. In addition to creating the 505(b)(2) NDA pathway that allows for follow-on applications relying on a reference drug product when some of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference, the Hatch-Waxman Amendments to the FDCA authorized the FDA to approve generic drugs that are the same as drugs previously approved for marketing under the NDA provisions of the statute pursuant to abbreviated new drug applications, or ANDAs. An ANDA relies on the preclinical and clinical testing conducted for a previously approved reference listed drug

66


 

(“RLD”) and must demonstrate to the FDA that the generic drug product is identical to the RLD with respect to the active ingredients, the route of administration, the dosage form, and the strength of the drug and also that it is “bioequivalent” to the RLD. The FDA is prohibited by statute from approving an ANDA when certain marketing or data exclusivity protections apply to the RLD.

If the FDA in the future were to approve an NDA for SB 11285 or another small-molecule drug product candidate, such a product would be expected to be designated as an RLD. Such a designation as an RLD would allow for a subsequent ANDA or 505(b)(2) NDA to rely in whole or in part on our RLD, as applicable. We cannot predict the interest of potential generic or follow-on competitors in the future market, whether someone will attempt to invalidate any period of 5-year or 3-year exclusivity that an approved small-molecule drug product candidate may receive or otherwise force the FDA to take other actions, or how quickly others may seek to come to market with competing products after any such marketing exclusivity period ends. In addition, should any such future generic or follow-on product be identified by the FDA as “therapeutically equivalent” to our relevant small-molecule drug product candidate, if or when approved and listed in the Orange Book, physicians and pharmacists consider it to be fully substitutable for our relevant RLD. By operation of certain state laws and numerous health insurance programs, the FDA’s designation of therapeutic equivalence often results in substitution of the generic drug without the knowledge or consent of either the prescribing physician or patient. Such competitive products may be able to immediately compete with us in each indication for which its small-molecule drug product candidates may have received approval.

The successful commercialization of our product candidates will depend in part on the extent to which governmental authorities and health insurers establish coverage and adequate reimbursement levels, as well as pricing policies. Failure to obtain or maintain adequate coverage and reimbursement for our product candidates, if approved, could limit our ability to market those products and decrease our ability to generate revenue.

The availability and adequacy of coverage and reimbursement by governmental healthcare programs such as Medicare and Medicaid, private health insurers and other third-party payors are essential for most patients to be able to afford products such as our product candidates, if approved. Even if we receive approval to market one or more of our product candidates in the future, our ability to achieve acceptable levels of coverage and reimbursement for such product candidates by governmental authorities, private health insurers and other organizations will have an effect on our ability to successfully commercialize and attract additional collaboration partners to invest in the development of, our product candidates. Assuming we obtain coverage for a given product by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require co-payments that patients find unacceptably high. We cannot be sure that coverage and reimbursement in the United States, the European Union or elsewhere will be available for any product that we may develop, and any reimbursement that may become available may be decreased or eliminated in the future.

Obtaining and maintaining reimbursement status is time-consuming and costly. No uniform policy for coverage and reimbursement for drug products exist among third-party payors in the United States. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance. Furthermore, rules and regulations regarding reimbursement change frequently, in some cases at short notice, and we believe that changes in these rules and regulations are likely.

Coverage and reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor’s determination that use of a product is:

a covered benefit under its health plan;
safe, effective and medically necessary;
appropriate for the specific patient;
cost-effective; and
neither experimental nor investigational.

There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. In the United States, third-party payors, including private and governmental payors, such as the Medicare and Medicaid programs, play an important role in determining the extent to which new drugs and biologics will be covered. The Medicare and

67


 

Medicaid programs increasingly are used as models for how private payors and other governmental payors develop their coverage and reimbursement policies for drugs and biologics. Some third-party payors may require pre-approval of coverage for new or innovative devices or drug therapies before they will reimburse healthcare providers who use such therapies. It is difficult to predict at this time what third-party payors will decide with respect to the coverage and reimbursement for our product candidates.

Third-party payors increasingly are challenging prices charged for pharmaceutical products and services, and many third-party payors may refuse to provide coverage and reimbursement for particular drugs when an equivalent generic/biosimilar drug or a less expensive therapy is available. It is possible that a third-party payor may consider our product candidate and other therapies as substitutable and only offer to reimburse patients for the less expensive product. Even if we show improved efficacy or improved convenience of administration with our product candidate over other available and comparable products, pricing of existing drugs may limit the amount we will be able to charge for its product candidate. These payors may deny or revoke the reimbursement status of a given drug product or establish prices for new or existing marketed products at levels that are too low to enable it to realize an appropriate return on our investment in product development. If coverage and reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize our product candidates and may not be able to obtain a satisfactory financial return on products that we may develop.

For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization. For example, under these circumstances, physicians may limit how much or under what circumstances they will prescribe or administer our products and patients may deliver to purchase such products. This, in turn, could affect our ability to commercialize our products successfully and impact our profitability, results of operations, financial condition, and future success.

Outside the United States, international operations are generally subject to extensive governmental price controls and other market regulations, and we believe the increasing emphasis on cost-containment initiatives in Europe, Canada and other countries has and will continue to put pressure on the pricing and usage of our product candidates. In many countries, the prices of medical products are subject to varying price control mechanisms as part of national health systems. Other countries allow companies to fix their own prices for medical products but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our product candidates. Accordingly, in markets outside the United States, the reimbursement for our products may be reduced compared with the United States and may be insufficient to generate commercially reasonable revenue and profits.

The delivery of healthcare in the European Union, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than European Union, law and policy. National governments and health service providers have different priorities and approaches to the delivery of healthcare and the pricing and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most European Union member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Coupled with ever-increasing European Union and national regulatory burdens on those wishing to develop and market products, this could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to commercialize any products for which we obtain marketing approval.

Moreover, increasing efforts by governmental and third-party payors in the United States, the European Union and other jurisdictions to cap or reduce healthcare costs may cause such organizations to limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our product candidates. We expect to experience pricing pressures in connection with the sale of any of our product candidates due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription drugs and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products.

The future commercial success of our product candidates will depend on the degree of market acceptance of our potential therapeutic products among physicians, patients, third-party payors and the medical community.

To date, we have no products authorized for marketing and we do not expect to be able to commercialize any of our product candidates for a number of years, if ever. Even if one or more of our product candidates are approved for commercialization, they may not achieve an adequate level of acceptance by physicians, patients and the medical community, and we may not become profitable. In addition, efforts to educate the medical community and third-party payors on the benefits of our future approved products may require significant resources and may never be successful which would prevent us from generating significant revenues or becoming profitable.

Market acceptance of our future products by physicians, patients and third-party payors will depend on a number of factors, many of which are beyond our control, including, but not limited to:

the clinical indications for which our product candidates are approved for marketing;
physicians, hospitals, cancer treatment centers and patients considering our product candidates as a safe and effective treatment;
the potential and perceived advantages of our product candidates over alternative treatments;
the prevalence and severity of any side effects;
product labeling or prescribing information requirements of the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities, or any risk mitigation measures that are required to be followed as part of the product’s marketing approval;
limitations or warnings contained in the product labeling approved by the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities, including any restrictions on concomitant use of other medications;
the timing of market introduction of our product candidates in relation to other potentially competitive products;
the cost and cost-effectiveness of our product candidates in relation to alternative treatments;
the amount of upfront costs or training required for physicians to administer our product candidates;
the availability of coverage and adequate reimbursement from third-party payors and government authorities;
the willingness of patients to pay out-of-pocket in the absence of comprehensive coverage and reimbursement by third-party payors and government authorities;
the relative convenience and ease of administration, including as compared to alternative treatments and competitive therapies;
support from patient advocacy groups;
the effectiveness of our sales and marketing efforts and distribution support; and
the presence or perceived risk of potential product liability claims.

If our product candidates fail to gain market acceptance after receiving regulatory approval, this will have a material adverse impact on our ability to generate revenues to provide a satisfactory, or any, return on our investments. Even if some products achieve market acceptance, the market may prove not to be large enough to allow us to generate significant revenues.

Healthcare legislative reform measures may have a negative impact on our business and results of operations.

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect our ability to profitably sell any product candidates for which we obtain marketing approval. Changes in regulations, statutes, or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements, (ii) additions or modifications to product labeling, (iii) the recall or discontinuation of our products, (iv) restriction on coverage, reimbursement, and pricing for our products, (v) transparency reporting obligations regarding transfers of value to healthcare

69


 

professionals or (vi) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect our business, financial condition, and results of operations.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the “ACA”), was passed, which substantially changed the way healthcare is financed by both governmental and private insurers, and significantly impacted the U.S. pharmaceutical industry. The ACA, among other things, subjected biological products to potential competition by lower-cost biosimilars, addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs and biologics that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations, established annual fees and taxes on manufacturers of certain branded prescription drugs and biologics, and created a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% (increased from 50% pursuant to the Bipartisan Budget Act of 2018, effective as of 2019) point-of-sale discounts off negotiated prices of applicable brand drugs and biologics to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs or biologics to be covered under Medicare Part D.

 

Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the ACA. However, following several years of litigation in the federal courts, in June 2021, the U.S. Supreme Court upheld the ACA when it dismissed a legal challenge to the ACA’s constitutionality. Further legislative and regulatory changes under the ACA remain possible, although the new federal administration under President Biden has signaled that it plans to build on the ACA and expand the number of people who are eligible for health insurance subsidies under it. It is unknown what form any such changes or any law would take, and how or whether it may affect the biopharmaceutical industry as a whole or our business in the future. We expect that changes or additions to the ACA, the Medicare and Medicaid programs, such as changes allowing the federal government to directly negotiate drug prices, and changes stemming from other healthcare reform measures, especially with regard to healthcare access, financing or other legislation in individual states, could have a material adverse effect on the health care industry in the United States.

 

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. On August 2, 2011, the Budget Control Act of 2011 was signed into law, which, among other things, resulted in reductions to Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2030, with the exception of a temporary suspension from May 1, 2020 through June 30, 2022 (a 1% sequester will apply from April 1, 2022 through June 30, 2022) due to the COVID-19 pandemic, unless additional Congressional action is taken. As another example, the 2021 Consolidated Appropriations Act signed into law on December 27, 2020 incorporated extensive healthcare provisions and amendments to existing laws, including a requirement that all manufacturers of drugs and biological products covered under Medicare Part B report the product’s average sales price, or ASP, to Department of Health and HHS beginning on January 1, 2022, subject to enforcement via civil money penalties.

 

Further, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription drugs. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. Although a number of these and other measures may require additional authorization to become effective, Congress and the current U.S. administration have each indicated that it will continue to seek new legislative and/or administrative measures to control drug costs. Any reduction in reimbursement from Medicare and other government programs may result in a similar reduction in payments from private payors. Moreover, in July 2021, President Biden issued a sweeping executive order on promoting competition in the American economy that includes several mandates pertaining to the pharmaceutical and healthcare insurance industries. Among other things, the executive order directs the FDA to work towards implementing a system for importing drugs from Canada (following on a Trump administration notice-and-comment rulemaking on Canadian drug importation that was finalized in October 2020). The Biden order also called on HHS to release a comprehensive plan to combat high prescription drug prices, and it includes several directives regarding the Federal Trade Commission’s oversight of potentially anticompetitive practices within the pharmaceutical industry. The drug pricing plan released by HHS in September 2021 in response to the executive order makes clear that the Biden Administration supports aggressive action to address rising drug prices, including allowing HHS to negotiate the cost of Medicare Part B and D drugs, but such significant changes will require either new legislation to be passed by Congress or time-consuming administrative

70


 

actions. Accordingly, there remains a large amount of uncertainty regarding the federal government’s approach to making pharmaceutical treatment costs more affordable for patients.

 

At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, California requires pharmaceutical manufacturers to notify certain purchasers, including health insurers and government health plans at least 60 days before any scheduled increase in the wholesale acquisition cost (“WAC”), of their product if the increase exceeds 16%, and further requires pharmaceutical manufacturers to explain whether a change or improvement in the product necessitates such an increase. Similarly, Vermont requires pharmaceutical manufacturers to disclose price information on certain prescription drugs, and to provide notification to the state if introducing a new drug with a WAC in excess of the Medicare Part D specialty drug threshold. In December 2020, the U.S. Supreme Court also held unanimously that federal law does not preempt the states’ ability to regulate pharmaceutical benefit managers, or PBMs, and other members of the healthcare and pharmaceutical supply chain, an important decision that may lead to further and more aggressive efforts by states in this area. Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our product candidates, if approved, or put pressure on our product pricing, which could negatively affect our business, results of operations, financial condition and prospects.

 

We expect that the ACA, the recent laws described above, and other healthcare reform measures that may be adopted in the future may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, new payment methodologies and additional downward pressure on the price that we receive for any approved product. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize or product candidates, if approved. Further, it is possible that additional governmental action will be taken in response to the COVID-19 pandemic.

 

Outside of the United States, particularly in the European Union, the coverage status and pricing of prescription pharmaceuticals and biologics is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. Furthermore, the requirements may differ across the European Union Member States. To obtain coverage and reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed. Also, at national level, actions have been taken to enact transparency and anti-gift laws (similar to the U.S. Physician Payments Sunshine Act) regarding payments between pharmaceutical companies and healthcare professionals.

Our business operations and current and future relationships with clinical investigators, healthcare professionals, consultants, third-party payors and customers may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws, health information privacy and security laws, and other healthcare laws. If we are unable to comply, or has not fully complied, with such laws, we could face substantial penalties.

Although we do not currently have any products on the market, our current and future operations may be directly, or indirectly through our relationships with clinical investigators, healthcare professionals, customers and third-party payors, subject to broadly applicable healthcare laws U.S. federal and state fraud and abuse and other healthcare laws and regulations, including, without limitation, the Anti-Kickback Statute. Healthcare providers, physicians and others play a primary role in the recommendation and prescription of any products for which we obtain marketing approval. These laws impact, among other things, our proposed sales, marketing and education programs and constrain our business and financial arrangements and relationships with third-party payors, healthcare professionals who participate in our clinical research program, healthcare professionals and others who recommend, purchase, or provide our approved products, and other parties through which we market, sell and distribute our products for which we obtain marketing approval. In addition, we may be subject to patient data privacy and security regulation by both the U.S. federal government and the states in which we conduct our business. Finally, our current and future operations are subject to additional healthcare-related statutory and regulatory requirements and enforcement by foreign regulatory authorities in jurisdictions in which we conduct our business.

71


 

the Anti-Kickback Statute, which prohibits, among other things, persons or entities from knowingly and willfully soliciting, offering, receiving or paying any remuneration (including any kickback, bribe, or certain rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, lease, order or recommendation of, any good, facility, item or service, for which payment may be made, in whole or in part, under U.S. federal and state healthcare programs such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, a claim including items or services resulting from a violation of the Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act (“FCA”);
federal civil and criminal false claims laws and civil monetary penalty laws, including the FCA, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, false or fraudulent claims for payment to, or approval by Medicare, Medicaid, or other federal healthcare programs, knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim or an obligation to pay or transmit money to the federal government, or knowingly concealing or knowingly and improperly avoiding or decreasing or concealing an obligation to pay money to the federal government. Manufacturers can be held liable under the FCA even when they do not submit claims directly to government payors if they are deemed to “cause” the submission of false or fraudulent claims. The FCA also permits a private individual acting as a “whistleblower” to bring actions on behalf of the federal government alleging violations of the FCA and to share in any monetary recovery;
HIPAA, which created new federal criminal and civil statutes that prohibit, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters. Similar to the Anti-Kickback Statute, a person or entity can be found guilty of violating HIPAA without actual knowledge of the statute or specific intent to violate it;
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”), and their implementing regulations, which impose certain obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information by covered entities subject to the rule, such as health plans, healthcare clearinghouses and certain healthcare providers, as well as their business associates that perform certain services involving the use or disclosure of individually identifiable health information and require notification to affected individuals and regulatory authorities of certain breaches of individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions;
federal legislation commonly referred to as Physician Payments Sunshine Act, enacted as part of the ACA, and its implementing regulations, which requires certain manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program to report annually to the CMS information related to certain payments and other transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists, chiropractors, and certain advanced non-physician healthcare practitioners) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members;
analogous state laws and regulations, including: state anti-kickback and false claims laws that may apply to claims involving healthcare items or services reimbursed by any third-party payor, including private insurers; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the U.S. federal government, or otherwise restrict payments that may be made to healthcare providers and other potential referral source; state laws and regulations that require drug manufacturers to file reports relating to pricing and marketing information, which requires tracking gifts and other remuneration and items of value provided to healthcare professionals and entities; state and local laws that require the registration of pharmaceutical sales

representatives; and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts; and
European and other foreign law equivalents of each of the laws, including reporting requirements detailing interactions with and payments to healthcare providers.

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products and to limit the distribution of product samples and impose requirements to ensure accountability in prescription drug sample distribution.

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry.

It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws. If our operations are found to be in violation of any of these laws or any other laws that may apply to us, we may be subject to significant sanctions, including civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participating in government funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, reputational harm and the curtailment or restructuring of our operations. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found not to be in compliance with applicable laws, that person or entity may be subject to significant criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Prohibitions or restrictions on sales or withdrawal of future marketed products could materially affect business in an adverse way.

The risk of us being found in violation of these laws is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts or otherwise have broad coverage. For example, the definition of the “remuneration” under the Anti-Kickback Statute has been interpreted to include anything of value. Further, courts have found that if “one purpose” of remuneration is to induce referrals, the Anti-Kickback Statute is violated.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws will involve substantial costs. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply with multiple jurisdictions with different compliance or reporting requirements increases the possibility that a biopharmaceutical company may run afoul of one or more of the requirements.

Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does not mean that we will be successful in obtaining marketing approval of our current and future therapeutic product candidates in other jurisdictions.

Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain marketing approval in any other jurisdiction, while a failure or delay in obtaining marketing approval in one jurisdiction may have a negative effect on the marketing approval process in others. For example, even if the FDA grants marketing approval of a product candidate, comparable foreign regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the United States, including additional preclinical studies or clinical trials as clinical studies conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our future products will also be subject to approval.

73


 

We may submit marketing applications in other countries in addition to the United States. Regulatory authorities in jurisdictions outside of the United States have requirements for approval of product candidates with which we must comply prior to marketing in those jurisdictions. Obtaining foreign marketing approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we fail to comply with the regulatory requirements in international markets and/or receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed.

We have never commercialized a product candidate before and may lack the necessary expertise, personnel and resources to successfully commercialize our products on our own or together with suitable partners.

We do not have a sales or marketing infrastructure and have no experience in the sale or marketing of biopharmaceutical products. To achieve commercial success for any approved product, we must develop or acquire a sales and marketing organization, outsource these functions to third parties or enter into partnerships.

We may decide to establish our own sales and marketing capabilities and promote our product candidates if and when regulatory approval has been obtained in the United States and the major European Union countries. There are risks involved if we decide to establish our own sales and marketing capabilities or enter into arrangements with third parties to perform these services. Even if we establish sales and marketing capabilities, we may fail to launch our products effectively or to market our products effectively since we have no experience in the sales and marketing of biopharmaceutical products. In addition, recruiting and training a sales force is expensive and time consuming and could delay any product launch. In the event that any such launch is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel. Factors that may inhibit our efforts to commercialize our products on our own include:

Our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel;
the inability of sales personnel to obtain access to or persuade adequate numbers of physicians to prescribe our products;
the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines;
unforeseen costs and expenses associated with creating an independent sales and marketing organization; and
costs of marketing and promotion above those anticipated by us.

If we enter into arrangements with third parties to perform sales and marketing services, our product revenues or the profitability of these product revenues to us could be lower than if we were to market and sell any products that we develop ourselves. Such collaborative arrangements with partners may place the commercialization of our products outside of our control and would make us subject to a number of risks including that we may not be able to control the amount or timing of resources that our collaborative partner devotes to our products or that our collaborator’s willingness or ability to complete its obligations, and our obligations under our arrangements may be adversely affected by business combinations or significant changes in our collaborator’s business strategy. In addition, we may not be successful in entering into arrangements with third parties to sell and market our products or may be unable to do so on terms that are favorable to us. Acceptable third parties may fail to devote the necessary resources and attention to sell and market our products effectively.

If we do not establish sales and marketing capabilities successfully, either on our own or in collaboration with third parties, we may not be successful in commercializing our products, which in turn would have a material adverse effect on our business, financial condition and results of operations.

Adverse events in the field of immuno-oncology could damage public perception of our current or future therapeutic product candidates and negatively affect our business.

The commercial success of our immuno-oncology product candidates, if approved, will depend in part on public acceptance of the use of cancer immunotherapies. Adverse events in marketed products, in clinical trials of our product candidates or in clinical trials of others developing similar products and the resulting publicity, as well as any other adverse events in the field of immuno-oncology that may occur in the future, could result in a decrease in demand for any products that we may

74


 

develop. If public perception is influenced by claims that the use of cancer immunotherapies is unsafe, whether related to our products or those of our competitors, our products may not be accepted by the general public or the medical community.

Future adverse events in immuno-oncology or the biopharmaceutical industry could also result in heightened governmental regulation, stricter labeling requirements and potential regulatory delays in the testing or approvals of our product candidates. Any increased scrutiny could delay or increase the costs of obtaining marketing approval for the product candidates we develop or prevent it from receiving marketing approval at all.

The market opportunities for any current or future immuno-oncology product candidates we develops, if approved, may be limited to those patients who are ineligible for established therapies or for whom prior therapies have failed, and may be small.

Cancer therapies are sometimes characterized as first-line, second-line or third-line, and the FDA often approves new therapies initially only for third-line use. When cancer is detected early enough, first-line therapy, usually chemotherapy, hormone therapy, surgery, radiation therapy or a combination of these, is sometimes adequate to cure the cancer or prolong life without a cure. Second- and third-line therapies are administered to patients when prior therapy is not effective. We expect to initially seek approval of our current and future immuno-oncology product candidates as a therapy for patients who have received one or more prior treatments. Subsequently, for those products that prove to be sufficiently beneficial, if any, we would expect to seek approval potentially as a first-line therapy, but there is no guarantee that product candidates we develop, even if approved, would be approved for first-line therapy, and, prior to any such approvals, we may have to conduct additional clinical trials.

In addition, subsequent developments in cancer biomarkers may demonstrate that our product candidates are not suitable for the treatment of certain cancers or subpopulations, thereby reducing the market opportunity for those product candidates. Even if we obtain significant market share for any product candidate, if approved, if the potential target populations are small, we may never achieve profitability without obtaining marketing approval for additional indications, including to be used as first- or second-line therapy or for other related cancer indications.

If the market opportunities for our product candidates are smaller than we believe they are, even assuming approval of a product candidate, our business may suffer.

Our projections of both the number of people who are affected by disease within our potential target indications, as well as the subset of these people who have the potential to benefit from treatment with our product candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including the scientific literature, healthcare utilization databases and market research, and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these diseases. The number of patients may turn out to be lower than expected. Likewise, the potentially addressable patient population for each of our product candidates may be limited or may not be amenable to treatment with our product candidates, and new patients may become increasingly difficult to identify or gain access to, which would adversely affect our business, financial condition and results of operations.

 

The COVID-19 pandemic has adversely affected many companies in the biotechnology industry and has adversely affected our business, in particular, in relation to planned and ongoing clinical trials. Other public health emergencies could also disrupt our activities and render our own or our service providers’ facilities inoperable or inaccessible and require us to curtail or cease operations.

 

COVID-19, a serious and sometimes fatal illness, and its variants have spread to every country in the world and throughout the United States. Many countries, as well as most states of the United States, reacted by instituting quarantines, “lockdowns” and other public health restrictions on leisure activities, work and travel. Although pandemic-related restrictions have been eased or removed in certain geographies, our business remains subject to pandemic-related controls, which may become more restrictive at any time. We rely on third-party manufacturers, distributors, information technology and software service providers, law and accounting firms, CROs, and consultants who are subject to, or may become subject to, pandemic-related controls. COVID-19 may also affect employees of third-party CROs located in affected geographies that we rely upon to carry out clinical trials. If these third parties cannot perform the services we require in a timely way and we cannot successfully implement replacements or workarounds, our business, results of operations, and financial condition could be harmed.

 

75


 

The continued spread of COVID-19 or variants thereof globally could adversely impact our preclinical or clinical trial operations, including our ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 if an outbreak occurs in their geography. For example, similar to other biopharmaceutical companies, we may experience delays in initiating preclinical studies, enrolling our clinical trials, or dosing of patients in our clinical trials as well as in activating new trial sites. Many physicians have reduced the frequency of patient office visits and barred office visits by third parties. Many patients have postponed visits to their physicians or testing at clinical laboratories or imaging centers. Patient enrollment or treatment or the execution of our product candidates could cause costly delays to clinical trial activities, which could adversely affect our ability to obtain regulatory approvals for our product candidates, increase our operating expenses, and have a material adverse effect on our financial results. Any negative impact COVID-19 has to patient enrollment or treatment or the execution of our product candidates could cause costly delays to clinical trial activities, which could adversely affect our ability to obtain regulatory approval for and to commercialize our product candidates, increase our operating expenses, and have a material adverse effect on our financial results. Also, there is a risk of corporate and other tax increases or decreases to current tax credits or reliefs as a result of government expenditures to address COVID-19, which could have a material adverse effect on our future financial results.

Additionally, timely enrollment and data collection in planned and ongoing clinical trials is dependent upon clinical trial sites that could be adversely affected by global health matters, such as pandemics. We are conducting clinical trials for our mAb2 product candidates in geographies that are currently being affected by the COVID-19. Some factors from the COVID-19 outbreak that may delay or otherwise adversely affect enrollment in the clinical trials of our mAb2 product candidates, as well as our business generally, include:

the potential diversion of healthcare resources away from the conduct of clinical trials to focus on pandemic concerns, including the attention of physicians serving as our clinical trial investigators, hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our prospective clinical trials;
limitations on travel that could interrupt key trial and business activities, such as clinical trial site initiations and monitoring, domestic and international travel by employees, contractors or patients to clinical trial sites, including any government-imposed travel restrictions or quarantines that will impact the ability or willingness of patients, employees or contractors to travel to our clinical trial sites or secure visas or entry permissions, a loss of face-to-face meetings and other interactions with potential partners, any of which could delay or adversely impact the conduct or progress of our prospective clinical trials;
the potential negative affect on the operations of our third-party manufacturers;
interruption in global shipping affecting the transport of clinical trial materials, such as patient samples, investigational drug product and conditioning drugs and other supplies used in our prospective clinical trials; and
business disruptions caused by potential workplace, laboratory and office closures and an increased reliance on employees working from home, disruptions to or delays in ongoing laboratory experiments.

 

The Ukraine conflict may adversely affect many companies in the biotechnology industry, in particular with respect to timely enrollment and data collection in planned and ongoing clinical trials and has adversely affected our business, in particular, in relation to planned and ongoing clinical trials.

The ongoing military conflict in Ukraine could materially disrupt our clinical trials, and increase our costs in this region. Although the length and impacts of any military action are highly unpredictable, clinical trial sites in Ukraine and neighboring regions could suspend or terminate trials, and patients and physicians could be forced to evacuate or voluntarily choose to relocate far from clinical trial sites, making them unavailable. We had planned clinical trials and clinical trial sites in Ukraine. Alternative sites will take time to identify and gain approval to compensate for our clinical trial activities in Ukraine. The potential negative impacts also include interruption in global shipping affecting the transport of clinical trial materials, such as patient samples, investigational drug product and other supplies used in clinical trials.

Risks Related to our Intellectual Property

We rely on patents and other intellectual property rights to protect our product candidates and our modular antibody technology platform, the enforcement, defense and maintenance of which may be challenging and costly. Failure to protect or enforce these rights adequately could harm our ability to compete and impair our business.

Our commercial success depends in part on obtaining and maintaining patents and other forms of intellectual property rights for our product candidates, methods used to manufacture those product candidates and/or methods for treating patients using those product candidates, or on in-licensing such rights. Failure to protect or to obtain, maintain or extend adequate patent and other intellectual property rights could materially adversely affect our ability to develop and market our products and product candidates.

Patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless and until a patent issues from such applications, and then only to the extent the issued claims cover the technology at issue. We cannot be certain that patents will be issued or granted with respect to applications that are currently pending, or that issued or granted patents will not later be found to be invalid or enforceable. The patent position of biopharmaceutical companies is generally uncertain because it involves complex legal and factual considerations that have in recent years been the subject of much litigation. The standards applied by the European Patent Office (“EPO”), the U.S. Patent and Trademark Office (“USPTO”), and foreign patent offices in granting patents are not always applied uniformly or predictably. For example, there is no uniform worldwide policy regarding patentable subject matter or the scope of claims allowable in biopharmaceutical patents. Consequently, patents may not issue from our pending patent applications. As such, we do not know the degree of future protection that we will obtain that relates to our proprietary product candidates and modular antibody technology platform. The scope of patent protection that the EPO and the USPTO will grant with respect to the bispecific antibodies in our product pipeline is uncertain. It is possible that the EPO and the USPTO will not allow broad antibody claims that cover antibodies closely related to our mAb2 product candidates as well as the specific antibody. As a result, upon receipt of EMA or FDA approval, competitors may be free to market antibodies almost identical to ours, including biosimilar antibodies, thereby decreasing our market share. However, a competitor cannot submit to the FDA an application for a biosimilar product based on one of our products until four years following the date of approval of our “reference product,” and the FDA may not approve such a biosimilar product until 12 years from the date on which the reference product was approved, with a potential six-month extension of exclusivity if certain pediatric studies are conducted and the results are reported to the FDA.

The patent prosecution process is expensive and time-consuming, and we and our current or future licensors, licensees or collaboration partners may not be able to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we or our licensors, licensees or collaboration partners will fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Further, the issuance, scope, validity, enforceability and commercial value of our and our current or future licensors’, licensees’ or collaboration partners’ patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued which protect our modular antibody technology platform or our product candidates, in whole or in part, or which effectively prevent others from commercializing competitive technologies and products. Our competitors may be able to circumvent our patents by developing similar or alternative product candidates in a non-infringing manner. Moreover, in some circumstances, we may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, relating to technology that we license from or license to third parties and are reliant on our licensors, licensees or collaboration partners. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. If our current or future licensors, licensees or collaboration partners fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our current or future licensors, licensees or collaboration partners are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. The patent examination process may require us or our current or future licensors, licensees or collaboration partners to narrow the scope of the claims of our or our licensors’, licensees’ or collaboration partners’ pending and future patent applications, which may limit the scope of patent protection that may be obtained.

We cannot assure you that all of the potentially relevant prior art relating to our patents and patent applications has been found. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing or, in some cases, not at all. Therefore, we cannot know with certainty whether we were the first to make the inventions claimed in our patents or pending

77


 

patent applications, or that we were the first to file for patent protection of such inventions. If such prior art exists, it can invalidate a patent or prevent a patent from issuing from a pending patent application. Furthermore, if third parties have filed such patent applications on or before March 15, 2013, an interference proceeding can be initiated by such third parties to determine who was the first to invent any of the subject matter covered by the patent claims of our applications. If third parties have filed such applications after March 15, 2013, a derivation proceeding can be initiated by such third parties to determine whether our invention was derived from theirs. Even where we have a valid and enforceable patent, we may not be able to exclude others from practicing our invention where the other party can show that they used the invention in commerce before our filing date or the other party benefits from a compulsory license.

We have pending patent applications at the USPTO, the EPO, and the patent offices of other foreign jurisdictions, and it is possible that we will need to defend other patents from challenges by others from time to time. Certain of our U.S. patent applications have been and may in the future be the subject of submissions of prior art by third parties. Even if patents do successfully issue, third parties may initiate an opposition, interference, re-examination, post-grant review, inter partes review, nullification or derivation action in court or before patent offices, or similar proceedings challenging the validity, enforceability or scope of such patents, which may result in the patent claims being narrowed, invalidated, or held unenforceable, in whole or in part. For example, opposition proceedings at the EPO are increasingly common, and are costly and time consuming to defend. Similar proceedings are available in other patent offices around the world. It is possible that one or more of our U.S. patents may be challenged by parties who file a request for post-grant review or inter partes review or ex parte reexamination. Post-grant proceedings are increasingly common in the United States and are costly to defend. Our patent rights may not provide us with a proprietary position or competitive advantages against competitors. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, or allow third parties to commercialize our product candidates and compete directly with us, without payment to us. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, regardless of the outcome, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates. Furthermore, even if the outcome is favorable to us, the enforcement of our intellectual property rights can be extremely expensive and time consuming.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and unsuccessful, and issued patents relating to one or more of our product candidates or our modular antibody technology platform could be found invalid or unenforceable if challenged in court.

To protect our competitive position, we may from time to time need to resort to litigation in order to enforce or defend any patents or other intellectual property rights owned by or licensed to us, or to determine or challenge the scope or validity of patents or other intellectual property rights of third parties. As enforcement of intellectual property rights is difficult, unpredictable and expensive, many of our or our collaboration partners’ adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions than we or our collaboration partners can. Accordingly, despite our or our collaboration partners’ efforts, we or our collaboration partners may not prevent third parties from infringing upon or misappropriating intellectual property rights we own or control, particularly in countries where the laws may not protect those rights as fully as in the United States and in Europe. We may fail in enforcing our rights, in which case our competitors may be permitted to use our technology without being required to pay it any license fees. In addition, however, litigation involving our patents carries the risk that one or more of our patents will be held invalid (in whole or in part, on a claim-by-claim basis) or held unenforceable. Such an adverse court ruling could allow third parties to commercialize our product candidates or use our modular antibody technology platform, and then compete directly with us, without payment to us.

If we were to initiate legal proceedings against a third party to enforce a patent relating to one of our products, the defendant could counterclaim that our patent is invalid or unenforceable. In patent litigation in the United States or in Europe, defendant counterclaims alleging invalidity or unenforceability are commonplace. A claim for a validity challenge may be based on failure to meet any of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. A claim for unenforceability assertion could be an allegation that someone connected with prosecuting the patent withheld relevant information from the USPTO or made a misleading statement, during prosecution. The outcome following legal assertions of invalidity and unenforceability during patent litigation is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on one or more of our product candidates or certain aspects of our modular antibody technology platform. Such a loss of patent protection could have a material adverse impact on our business. Interference or

78


 

derivation proceedings provoked by third parties or brought by it or declared by the USPTO may be necessary to determine the priority of inventions with respect to our patents or patent applications. An unfavorable outcome could require us to cease using the related technology or to attempt to have rights licensed to us from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms or at all, or if a non-exclusive license is offered and our competitors gain access to the same technology. Further, litigation could result in substantial costs and diversion of management resources, regardless of the outcome, and this could harm our business and financial results. Patents and other intellectual property rights also will not protect our technology if competitors design around our protected technology without infringing our patents or other intellectual property rights. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions, or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our common stock.

Intellectual property rights of third parties could adversely affect our ability to commercialize our product candidates, such that we could be required to litigate or obtain licenses from third parties in order to develop or market our product candidates. Such litigation is, and will continue to be, costly and any required licenses may not be available on commercially reasonable terms.

Third-party claims of intellectual property infringement may prevent or delay our development and commercialization efforts. Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. However, our research, development and commercialization activities may be subject to claims that we infringe or otherwise violate patents or other intellectual property rights owned or controlled by third parties. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, derivation proceedings, oppositions and inter partes reexamination proceedings before the USPTO, and corresponding foreign patent offices. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are pursuing development candidates.

In particular, we are aware of a “method of use” patent issued in 2021 in the United States to E.R. Squibb & Sons, L.L.C. that expires in 2029, subject to the timely payment of maintenance fees and absent any patent term extension, and which includes claims directed to a method for treating cancer in a subject comprising administering to the subject an anti-LAG-3 antibody and an anti-PD-L1 antibody, which antibodies are specified in a subclaim as being in a bispecific molecule. We believe, based on our review of this U.S. patent, that the patent claims are impermissibly broad and that there would be strong arguments available to us should we decide to challenge its validity in court or USPTO post-grant proceedings, based on prior art and lack of written description and enablement for the entire scope of the claims. If we succeed in developing and obtaining regulatory approval to market our product candidate FS118 in the future, this patent, prior to its expiration, could impact our commercial plans for FS118 in the United States. We do not expect the patent to have any impact on commercialization of FS118 outside of the United States, and we do not expect the patent to impact our pre-commercial development of FS118 inside or outside of the United States. We are also aware of a “second medical use” patent issued in 2021 in Europe to BMS, which includes claims protecting until 2036 (subject to the timely payment of annual renewal fees and absent any supplementary protection certificates based on the patent) an anti-PD-1 or anti-PD-L1 antibody that inhibits PD-1 activity for use in a method for treating a subject identified as HPV positive and afflicted with a tumor derived from a HPV positive squamous cell carcinoma head and neck cancer, as well as the method comprising administering to the subject a therapeutically effective amount of the antibody. Multiple parties, including Regeneron Pharmaceuticals, Inc. and Merck Sharp and Dohme Corp, have filed oppositions at the European Patent Office challenging the validity of this European patent. We believe, based on our review of this European patent and the oppositions that have been filed, that there are strong grounds to argue that the patent is invalid due to lack of novelty and inventive step based on prior art as well as impermissible added matter and lack of sufficiency. If not revoked or amended to a form that poses no or a sufficiently reduced risk to our business, this patent, prior to its expiration, could impact our commercial plans for FS118 and FS222 in Europe, but we do not expect the patent to impact our pre-commercial development efforts. Patent litigation is costly and time-consuming and there is no assurance that we would prevail, should we initiate or defend such litigation. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that we may be subject to claims of infringement of the patent rights of third parties.

Our competitive position may suffer if patents issued to third parties or other third-party intellectual property rights cover our products or product candidates or elements thereof, our manufacture or uses relevant to our development plans, the targets of

79


 

our mAb2 product candidates, or other attributes of our mAb2 product candidates or our mAb2 technology. In such cases, we may not be in a position to develop or commercialize products or product candidates unless we successfully pursue litigation to nullify or invalidate the third-party intellectual property right concerned or enter into a license agreement with the intellectual property right holder, if available on commercially reasonable terms or at all.

It is also possible that we fail to identify relevant patents or patent applications. For example, certain U.S. applications filed after November 29, 2000 that will not be filed outside the United States may remain confidential until issuance of a patent. In general, patent applications in the United States and elsewhere are published approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications relating to our products or platform technology could have been filed by others without our knowledge. Furthermore, we operate in a highly competitive field, and given our limited resources, it is unreasonable to monitor all patent applications purporting to gain broad coverage in the areas in which we are active. Additionally, pending patent applications which have been published can, subject to certain limitations, be later amended in a manner that could cover our platform technologies, our products or the use of our products.

Parties making claims of infringement against us or defending against our invalidity actions may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. If we fail in any such dispute, in addition to being forced to pay damages, we or our licensees may be temporarily or permanently prohibited from commercializing any of our product candidates that are held to be infringing. We might, if possible, also be forced to redesign product candidates so that we no longer infringe the third-party intellectual property rights. We may be required to seek a license to any such technology that we are found to infringe, which license may not be available on commercially reasonable terms, or at all. Even if we or our collaboration partners obtain a license, it may be non-exclusive; thereby giving our competitors access to the same technologies licensed to us or our licensors or collaboration partners. Moreover, such a license may require us to pay royalties to the licensor; thus, reducing our expected revenues. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a patent in the United States. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business.

In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, we could have a substantial adverse effect on our share price. Such litigation or proceedings could substantially increase our operating losses and reduce our resources available for development activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.

In addition, if the breadth or strength of protection provided by our or our collaboration partners’ patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.

If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we could lose intellectual property rights that are important to our business.

We are a party to license agreements, and we may in the future need to obtain additional licenses from others to advance our research and development activities or allow the commercialization of our product candidates. Our current license agreements impose, and we expect that future license agreements will impose, various development, diligence, commercialization and other obligations on us. In spite of our efforts, our current or future licensors might conclude that we have materially breached our obligations under such license agreements and might therefore terminate the license agreements, thereby removing or limiting our ability to develop and commercialize product candidates and otherwise use technology covered by these license agreements. If these in-licenses are terminated, or if the underlying patents fail to provide the intended exclusivity, competitors or other third parties would have the freedom to seek regulatory approval of, and to market, products identical to ours and we may be required to cease our development and commercialization of our

80


 

product candidates. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and prospects.

Moreover, disputes may arise regarding intellectual property subject to a licensing agreement, including:

the scope of rights granted under the license agreement and other interpretation-related issues;
the extent to which our product candidates, technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;
the sublicensing of patent and other rights under our collaborative development relationships;
our diligence obligations under the license agreement and what activities satisfy those diligence obligations;
the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and our partners; and
the priority of invention of patented technology.

In addition, the agreements under which we currently license intellectual property or technology from third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations, and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected mAb2 product candidates, which could have a material adverse effect on our business, financial conditions, results of operations, and prospects.

We may not be successful in obtaining or maintaining necessary rights to our product candidates through acquisitions and in-licenses.

Because our programs may require the use of proprietary rights held by third parties, the growth of our business will likely depend in part on our ability to acquire or in-license such proprietary rights. We may be unable to acquire or in-license any compositions, methods of use, processes, or other third-party intellectual property rights from third parties that we identify as necessary for our product candidates. The licensing and acquisition of third-party intellectual property rights is a competitive area, and a number of more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due to our size, cash resources and greater clinical development and commercialization capabilities.

In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment. If we are unable to successfully obtain a license to third-party intellectual property rights necessary for the development of a product candidate or program, we may have to abandon development of that product candidate or program, and our business and financial condition could suffer.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in our markets of interest. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively, and our business may be adversely affected. If other entities use trademarks similar to ours in different jurisdictions, or have rights that are senior to ours, it could interfere with our use of our current trademarks throughout the world.

81


 

If we do not obtain protection under the Hatch-Waxman Amendments and similar non-U.S. legislation for extending the term of patents covering each of our product candidates, our business may be materially harmed.

Patents have a limited duration. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. Even if patents covering our product candidates, their manufacture or use are obtained, once the patent life has expired, we may be open to competition from competitive medications, including biosimilar medications. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and in-licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments to the FDCA, and similar legislation in Europe. The Hatch-Waxman Amendments permit a patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. The patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, and only one patent applicable to an approved drug may be extended. Patent term extension also may be available in certain foreign countries upon regulatory approval of our product candidates. However, we may not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension, as well as the scope of the protection during such an extension, could be less than we request. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for that product will be shortened and our competitors may obtain approval to market competing products sooner than we expect. As a result, our revenue from applicable products could be reduced, possibly materially.

We enjoy only limited geographical protection with respect to certain patents and may face difficulties in certain jurisdictions, which may diminish the value of intellectual property rights in those jurisdictions.

We often file our first patent application (i.e., priority filing) in the United Kingdom or with the USPTO. International applications under the Patent Cooperation Treaty (“PCT”), are usually filed within 12 months after the priority filing. Based on the PCT filing, national and regional patent applications may be filed in additional jurisdictions where we believe our product candidates may be marketed. We have so far not filed for patent protection in all national and regional jurisdictions where such protection may be available. In addition, we may decide to abandon national and regional patent applications before grant. Finally, the grant proceeding of each national/regional patent is an independent proceeding which may lead to situations in which applications might be refused by certain patent offices, while granted by others, and the scope of patent protection may vary for the same product candidate or technology.

Competitors may use our and our collaboration partners’ technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we and our licensors or collaboration partners have patent protection, but enforcement is not as strong as that in the United States and Europe. These products may compete with our product candidates, and our and our collaboration partners’ patents or other intellectual property rights may not be effective or sufficient to prevent them from competing with us.

The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws in the United States and Europe, and companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. If we encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the intellectual property rights important for our business in such jurisdictions, the value of these rights may be diminished, and we may face additional competition from others in those jurisdictions.

Some countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, some countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patents. If we or any of our licensors are forced to grant a license to third parties with respect to any patents relevant to

82


 

our business, our competitive position may be impaired, and our business and results of operations may be adversely affected.

Proceedings to enforce our and our collaboration partners’ patent rights in foreign jurisdictions could result in substantial costs and divert our and our collaboration partners’ efforts and attention from other aspects of our business, could put our and our collaboration partners’ patents at risk of being invalidated or interpreted narrowly and our and our collaboration partners’ patent applications at risk of not issuing and could provoke third parties to assert claims against us or our licensors or collaboration partners. We or our collaboration partners may not prevail in any lawsuits that we or our licensors or collaboration partners initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:

others may be able to make products that are the same as or similar to our product candidates but that are not covered by the claims of the patents that we own or have exclusively licensed;
the patents of third parties may have an adverse effect on our business;
we or any current or future licensors or strategic partners might not have been the first to conceive or reduce to practice the inventions covered by the issued patent or pending patent application that we own or have exclusively licensed;
we or any future licensors or strategic partners might not have been the first to file patent applications relating to certain of our inventions;
others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property rights;
it is possible that our pending patent applications will not lead to issued patents;
issued patents that we own or have exclusively licensed may not provide us with any competitive advantage, or may be held invalid or unenforceable, as a result of legal challenges by our competitors;
our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;
third parties performing manufacturing or testing for us using our products or technologies could use the intellectual property of others without obtaining a proper license; and
we may not develop additional technologies that are patentable.

Changes in patent laws or patent jurisprudence could diminish the value of patents in general, thereby impairing our ability to protect our products.

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involves both technological complexity and legal complexity. Therefore, obtaining and enforcing biopharmaceutical patents is costly, time-consuming and inherently uncertain. In addition, the America Invents Act (the “AIA”) has been enacted in the United States, resulting in significant changes to the U.S. patent system.

An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned to a “first-to-file” system for deciding which party should be granted a patent when two or more patent applications are filed by different parties claiming the same invention. A third party that files a patent application in the USPTO after that date but before we do could therefore be awarded a patent relating to an invention of ours even if we had made the invention before it was made by the

83


 

third party. This requires us to be cognizant of the time from invention to filing of a patent application, but circumstances could prevent us from promptly filing patent applications on our inventions.

Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit and providing opportunities for third parties to challenge any issued patent in the USPTO via various proceedings including, e.g., post-grant review, inter partes review, and derivation proceedings. This applies to all of our U.S. patents, even those issued before March 16, 2013. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in U.S. federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action. The AIA and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.

Additionally, the U.S. Supreme Court and the Court of Appeals for the Federal Circuit have ruled on patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and protect other proprietary information.

We consider proprietary trade secrets, confidential know-how and unpatented know-how to be important to our business. We may rely on trade secrets or confidential know-how to protect our technology, especially where patent protection is believed to be of limited value. However, trade secrets and confidential know-how are difficult to maintain as confidential.

To protect this type of information against disclosure or appropriation by competitors, our policy is to require our employees, consultants, contractors and advisors to enter into confidentiality agreements and invention assignment agreements with us. However, we cannot be certain that such agreements have been entered into with all relevant parties, and we cannot be certain that our trade secrets and other confidential proprietary information will not be disclosed or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Current or former employees, consultants, contractors and advisers may unintentionally or willfully disclose our confidential information to competitors, and confidentiality agreements may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Enforcing a claim that a third party obtained illegally and is using trade secrets or confidential know-how is expensive, time consuming and unpredictable. The enforceability of confidentiality agreements may vary from jurisdiction to jurisdiction. Furthermore, if a competitor lawfully obtained or independently developed any of our trade secrets, we would have no right to prevent such competitor from using that technology or information to compete with us, which could harm our competitive position. Additionally, if the steps taken to maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties for misappropriating the trade secret.

Failure to obtain or maintain trade secrets or confidential know-how trade protection could adversely affect our competitive position. Moreover, our competitors may independently develop substantially equivalent proprietary information and may even apply for patent protection in respect of the same. If successful in obtaining such patent protection, our competitors could limit our use of our trade secrets or confidential know-how.

Under certain circumstances, we may also decide to publish some know-how to attempt to prevent others from obtaining patent rights relating to such know-how.

84


 

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property or claiming ownership of what we regard as our own intellectual property.

Many of our employees, including our senior management, were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Some of these employees executed proprietary rights, non-disclosure and non-competition agreements in connection with such previous employment. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees have used or disclosed confidential information or intellectual property, including trade secrets or other proprietary information, of any such employee’s former employer. Litigation may be necessary to defend against these claims.

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel or sustain damages. Such intellectual property rights could be awarded to a third party, and we could be required to obtain a license from such third party to commercialize our technology or products. Such a license may not be available on commercially reasonable terms or at all. Even if we successfully prosecute or defend against such claims, litigation could result in substantial costs and distract management.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Periodic maintenance and annuity fees on any issued patent are due to be paid to the USPTO, the EPO and foreign patent agencies in several stages over the lifetime of the patent. The USPTO, the EPO and various foreign governmental patent agencies require compliance with a number of procedural, documentation, fee payment and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If we or our licensors or collaboration partners fail to maintain the patents and patent applications relating to our product candidates, our competitors might be able to enter the market, which would have an adverse effect on our business.

Risks Related to our Dependence on Third Parties

We rely, and expect to continue to rely, on third parties, including independent clinical investigators, contracted laboratories and CROs, to conduct our preclinical studies and clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed.

We have relied upon and plan to continue to rely upon third parties, including independent clinical investigators, contracted laboratories and third-party CROs, to conduct our preclinical studies and clinical trials in accordance with applicable regulatory requirements and to monitor and manage data for our ongoing preclinical and clinical programs. We rely on these parties for execution of our preclinical studies and clinical trials, and controls only certain aspects of their activities. Nevertheless, we are responsible for ensuring that each of our studies and trials is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards, and our reliance on these third parties does not relieve us of our regulatory responsibilities. We and our third-party contractors and CROs are required to comply with GLP, as applicable, and GCP requirements, which are regulations and guidelines enforced by the FDA, the EMA, the MHRA, and other comparable foreign regulatory authorities for all of our products in clinical development. Regulatory authorities enforce these GLPs and GCPs through periodic inspections of laboratories conducting GLP studies, and clinical trial sponsors, principal investigators, CROs, and trial sites when auditing for GCP compliance. If we, our investigators or any of our CROs or contracted laboratories fail to comply with applicable GLPs and GCP, as applicable, the data generated in our preclinical studies and clinical trials may be deemed unreliable and the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities may require us to perform additional preclinical studies or clinical trials before approving our marketing applications for our therapeutic product candidates. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our preclinical studies or clinical trials comply with applicable GLP or GCP regulations. In addition, our clinical trials must be conducted with product produced in

85


 

compliance with applicable cGMP regulations. Our failure to comply with these regulations may require us to repeat preclinical studies or clinical trials, which would delay the regulatory approval process.

Further, these laboratories, investigators and CROs are not our employees and we will not be able to control, other than by contract, the amount of resources, including time, which they devote to our product candidates and clinical trials. If independent laboratories, investigators or CROs fail to devote sufficient resources to the development of our product candidates, or if their performance is substandard, it may delay or compromise the prospects for approval and commercialization of any product candidates that we develop. In addition, the use of third-party service providers requires us to disclose our proprietary information to these parties, which could increase the risk that this information will be misappropriated.

Our CROs have the right to terminate their agreements with us in the event of an uncured material breach. In addition, some of our CROs have an ability to terminate their respective agreements with us if it can be reasonably demonstrated that the safety of the subjects participating in our clinical trials warrants such termination, if we make a general assignment for the benefit of our creditors or if we are liquidated.

There is a limited number of third-party service providers that specialize or have the expertise required to achieve our business objectives. If any of our relationships with these third-party laboratories, CROs or clinical investigators terminate, we may not be able to enter into arrangements with alternative laboratories, CROs or investigators or to do so in a timely manner or on commercially reasonable terms. If laboratories, CROs or clinical investigators do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our preclinical or clinical protocols, regulatory requirements or for other reasons, our preclinical studies or clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates. As a result, our results of operations and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed.

Switching or adding additional laboratories or CROs (or investigators) involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new laboratory or CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. Though we carefully manages our relationships with our contracted laboratories and CROs, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and results of operations.

In addition, clinical investigators may serve as scientific advisors or consultants to us from time to time and may receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or the FDA concludes that the financial relationship may have affected the interpretation of the preclinical study or clinical trial, the integrity of the data generated at the applicable preclinical study or clinical trial site may be questioned and the utility of the preclinical study or clinical trial itself may be jeopardized, which could result in the delay or rejection by the FDA. Any such delay or rejection could prevent us from commercializing our clinical-stage product candidate or any future therapeutic product candidates it may develop.

The manufacture of biotechnology products is complex, and manufacturers often encounter difficulties in production. If we or any of our third-party manufacturers encounter such difficulties, or otherwise fail to comply with their contractual obligations, the development or commercialization of our product candidates could be delayed or stopped.

The manufacture of biotechnology products is generally complex and requires significant expertise and capital investment. We and our contract manufacturers must comply with cGMP regulations and guidelines for clinical trial product manufacture and for commercial product manufacture. Manufacturers of biotechnology products often encounter difficulties in production, particularly in scaling up, addressing product quality, product comparability, validating production processes and mitigating potential sources of contamination. These problems include difficulties with raw material procurement, production costs and yields, quality control, product quality, including stability of the product, quality assurance testing, operator error, shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations. Furthermore, if microbial, viral or other contaminations are discovered in therapeutic products or in the manufacturing facilities in which our product candidates are made, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination.

86


 

 

Manufacturing facilities require commissioning and validation activities to demonstrate that they operate as designed, and are subject to government inspections by the FDA, the EMA, the MHRA, and other comparable foreign regulatory authorities. If our third-party manufacturers are unable to reliably produce products to specifications acceptable to the regulatory authorities, we may not obtain or maintain the approvals we need to manufacture our product candidates. Further, manufacturing facilities may fail to pass government inspections prior to or after the commercial launch of our product candidates, which would cause significant delays and additional costs required to remediate any deficiencies identified by the regulatory authorities. Any of these challenges could delay completion of clinical trials, increase clinical trial costs, delay approval of our product candidate, impair commercialization efforts, increase our cost of goods, and have an adverse effect on our business, financial condition, results of operations and growth prospects.

 

We cannot assure you that manufacturing problems, including supply chain disruptions of any of mAb2 product candidates or other products will not occur in the future. Any delay or interruption in the supply of preclinical or clinical trial supplies, including any delays arising from circumstances related to the COVID-19 pandemic, could delay the completion of these trials, increase the costs associated with maintaining these trial programs or require bridging clinical trials or the repetition of one or more clinical trials or even terminate trials completely.

 

In addition, as product candidates are developed through preclinical studies to later-stage clinical trials towards approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize processes and results. Any of these changes could cause our current product candidates or any future product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials conducted with the altered materials. Such changes may also require additional testing, or notification to, or approval by the FDA, the EMA, the MHRA, or comparable foreign regulatory authorities. This could delay completion of clinical trials, require the conduct of bridging clinical trials or studies, require the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our current product candidates and any future product candidates and/or jeopardize our ability to commence product sales and generate revenue.

We rely on third parties to supply and manufacture our product candidates, and we expect to continue to rely on third parties to manufacture our products, if approved. The development of such product candidates and the commercialization of any products, if approved, could be stopped, delayed or made less profitable if any such third party fails to provide us with sufficient quantities of product candidates or products or fails to do so at acceptable quality levels or prices or fails to maintain or achieve satisfactory regulatory compliance.

We do not currently have the infrastructure or capability internally to manufacture our product candidates for use in the conduct of our preclinical studies and clinical trials or for commercial supply if our products are approved. We rely on, and expect to continue to rely on, CMOs. We currently rely mainly on a few CMOs for the manufacturing of our product candidates. Any replacement of our CMOs could require significant effort and expertise because there may be a limited number of qualified CMOs. Reliance on third-party providers may expose us to more risk than if we were to manufacture our product candidates ourselves. We are dependent on our CMOs for the production of our product candidates in accordance with relevant regulations, such as cGMP, which includes, among other things, quality control, quality assurance and the maintenance of records and documentation. Moreover, many of the third parties with whom we contracts may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting product development activities that could harm our competitive position.

If we were to experience an unexpected loss of supply of or if any supplier were unable to meet our demand for any of our product candidates, we could experience delays in our research or planned clinical trials or future commercialization activities. We could be unable to find alternative suppliers of acceptable quality, in the appropriate volumes and at an acceptable cost. Moreover, our suppliers are often subject to strict manufacturing requirements and rigorous testing requirements, which could limit or delay production. The long transition periods needed to switch manufacturers and suppliers, if necessary, could significantly delay our clinical studies and the commercialization of our products, if approved, which could materially adversely affect our business, financial condition and results of operation.

In complying with the applicable manufacturing regulations of the FDA, the EMA, the MHRA, and other comparable foreign regulatory authorities, we and our third-party suppliers must spend significant time, money and effort in the areas of design and development, testing, production, record-keeping and quality control to assure that the products meet applicable specifications and other regulatory requirements. The failure to comply with these requirements could result in an

87


 

enforcement action against us, including the seizure of products and shutting down of production. We and any of these third-party suppliers may also be subject to audits by the FDA, the EMA, the MHRA, or other comparable foreign regulatory authorities. If any of our third-party suppliers fails to comply with cGMP or other applicable manufacturing regulations, our ability to develop and commercialize our future therapeutics products could suffer significant interruptions. We face risks inherent in relying on a single CMO, as any disruption, such as a fire, natural hazards, disease outbreaks including but not limited to the ongoing COVID-19 pandemic, or vandalism at the CMO could significantly interrupt our manufacturing capability. All of our CMOs currently do not have alternative production plans in place or disaster-recovery facilities available. In case of a disruption, we will have to establish alternative manufacturing sources. This would require substantial capital on our part, which we may not be able to obtain on commercially acceptable terms or at all. Additionally, we would likely experience months of manufacturing delays as the CMO builds or locates replacement facilities and seeks and obtains necessary regulatory approvals. If this occurs, we will be unable to satisfy manufacturing needs on a timely basis, if at all.

The manufacturing of all of our mAb2 product candidates requires using cells that are stored in a cell bank. We have one master cell bank for each product manufactured in accordance with cGMP. Working cell banks have not yet been manufactured. Half of each master cell bank is stored at a separate site so that in case of a catastrophic event at one site we believe sufficient vials of the master cell banks are left at the alternative storage site to continue manufacturing. We believe sufficient working cell banks could be produced from the vials of the master cell bank stored at a given site to assure product supply for the future. However, it is possible that we could lose multiple cell banks and have our manufacturing significantly impacted by the need to replace these cell banks, which could materially adversely affect our business, financial condition and results of operations.

We rely and expect to continue to rely on collaborative partners regarding the development of certain of our research programs and product candidates. If we are not able to maintain our current relationships or enter into new strategic relationships, our business, financial condition, commercialization prospects and results of operations may be adversely affected.

We are, and expect to continue to be, dependent on partnerships with partners relating to the development and commercialization of certain of our existing and future research programs and product candidates. We currently have collaborative research relationships with each of Janssen, AstraZeneca, Ares, Denali and Kymab for the development of certain mAb2 product candidates resulting from such collaborations. In addition, we have a clinical collaboration agreement with Roche on the use of the PD-L1 checkpoint inhibitor atezolizumab (Tecentriq®) in combination cohorts of the SB 11285 trial and with Merck & Co. on the use of PD-1 checkpoint inhibitor pembrolizumab (Keytruda®) in combination cohorts of the FS120 trial. We have, and may in the future, depending on our business strategy, continue to have discussions on potential partnering opportunities with various pharmaceutical companies. If we fail to enter into or maintain collaborations on reasonable terms or at all, our ability to develop our existing or future research programs and product candidates could be delayed, the commercial potential of our product could change, and our costs of development and commercialization could increase. Furthermore, we may find that our programs require the use of intellectual property rights held by third parties, and the growth of our business may depend in part on our ability to acquire or in-license these intellectual property rights.

Our dependence on collaborative partners subjects us to a number of risks, including, but not limited to, the following:

we may not be able to control the amount and timing of resources that the collaboration partner devotes to our research programs and product candidates;
for collaboration agreements where we are solely or partially responsible for funding development expenses through a defined milestone event, the payments we receive from the collaboration partner may not be sufficient to cover the expenses we have or would need to incur in order to achieve that milestone event;
we may be required to relinquish significant rights to our collaborative partners, including rights to exploit our intellectual property and marketing and distribution rights;
if the development of the relevant product candidates is not successful, our anticipated payments under any partnership agreement (e.g., royalty payments for licensed products) may not materialize;
we rely on the information and data received from third parties regarding their research programs and product candidates and will not have control of the process conducted by the third party in gathering and composing such data and information;

88


 

if rights to develop and commercialize our product candidates that are subject to collaborations revert to us for any reason, we may not have sufficient financial resources to develop such product candidates, which may result in us failing to recognize any value from our investments in developing such product candidates;
a collaborative partner may develop a competing product either by itself or in collaboration with others, including one or more of our competitors, or seek to restrict us from working with other collaborators that may compete with our partner’s products, which could deprioritize the development of our products;
our collaborative partners’ willingness or ability to complete their obligations under our partnership arrangements may be adversely affected by business combinations or significant changes in a collaborative partner’s business strategy;
we may experience delays in, or increases in the costs of, the development of our research programs and mAb2 product candidates due to the termination or expiration of collaborative research and development arrangements;
we may have disagreements with collaborative partners, including disagreements over proprietary rights, contract interpretation, non-competition limitations, or the preferred course of development, that might cause delays or termination of the research, development or commercialization of our product candidates, might lead to additional responsibilities for us with respect to our product candidates, or might result in litigation or arbitration, any of which may be time-consuming and expensive;
collaborative partners may not properly maintain or defend our intellectual property rights or may use proprietary information in such a way as to invite litigation or other intellectual property-related proceedings that could invalidate our intellectual property or jeopardize our proprietary information or expose us to potential litigation; or
collaborative partners may infringe or otherwise violate the intellectual property rights of third parties, which may expose us to litigation and potential liability.

We face significant competition in seeking appropriate collaborative partners. Our ability to reach a definitive agreement for a partnership will depend, among other things, upon an assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed partnership and the proposed collaborator’s evaluation of a number of factors. These factors may include the design or results of preclinical studies or clinical trials, the likelihood of regulatory approval, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such mAb2 product candidate to patients, the potential of competing products, the existence of any uncertainty with respect to our ownership of technology (which can exist if there is a challenge to such ownership regardless of the merits of the challenge) and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a partnership could be more attractive than the one with us.

We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of the product candidate for which we are seeking to collaborate, reduce or delay our development program or one or more of our other development programs, delay our potential commercialization, reduce the scope of any sales or marketing activities or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop mAb2 product candidates or bring them to market and generate product revenue.

Risks Related to our Business Operations, Employee Matters and Managing Growth

Our future growth and ability to compete depends on retaining our key personnel and recruiting additional qualified personnel.

Our success depends upon the continued contributions of our key management, scientific and technical personnel, many of whom have been instrumental for us and have substantial experience with our mAb2 product candidates, mAb2 technology and modular antibody technology platform. We are highly dependent upon our senior management, particularly Eliot Forster, our Chief Executive Officer, Neil Brewis, our Chief Scientific Officer, and Louis Kayitalire, our Chief Medical Officer, as well as our senior scientists and other members of our senior management team.

The loss of key managers and senior scientists could delay our research and development activities. In addition, our ability to compete in the highly competitive biotechnology and pharmaceutical industries depends upon our ability to attract and retain highly qualified management, scientific and medical personnel. Many other biotechnology and pharmaceutical companies and academic institutions that we compete with for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the industry than we do. Therefore, we might not be able to attract or retain these key persons on conditions that are economically acceptable. Furthermore, we will need to recruit new managers and qualified scientific personnel to develop our business if we expand into fields that will require additional skills. Our inability to attract and retain these key persons could prevent us from achieving our objectives and implementing our business strategy, which could have a material adverse effect on our business and prospects.

We expect to expand our development, regulatory and sales and marketing capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

We expect to experience growth in the number of our employees and the scope of our operations, particularly in the areas of drug development, regulatory affairs and sales and marketing. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, shareholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our shares.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our shares.

 

Our management will be required to assess the effectiveness of these controls annually. However, for as long as we are a Small Reporting Company, as defined by the SEC rules, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal controls over financial reporting pursuant to Section 404. An independent assessment of the effectiveness of our internal controls over financial reporting could detect problems that our management’s assessment might not. Undetected material weaknesses in our internal controls over financial reporting could lead to financial statement restatements and require us to incur the expense of remediation.

 

90


 

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

 

We are subject to certain reporting requirements of the Exchange Act. Our disclosure controls and procedures are designed to reasonably assure that information required to be disclosed by us in reports we file or submit under the Exchange Act is accumulated and communicated to management, recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements or insufficient disclosures due to error or fraud may occur and not be detected.

Our business is subject to economic, political, regulatory and other risks associated with international operations.

As a company based in the United Kingdom, our business is subject to risks associated with conducting business internationally. Accordingly, our future results could be harmed by a variety of factors, including:

economic weakness, including inflation, or political instability in particular non-U.S. economies and markets;
differing regulatory requirements for product approvals;
differing jurisdictions could present different issues for securing, maintaining or obtaining freedom to operate in such jurisdictions;
potentially reduced protection for intellectual property rights;
difficulties in compliance with different, complex and changing laws, regulations and court systems of multiple jurisdictions and compliance with a wide variety of foreign laws, treaties and regulations;
changes in non-U.S. regulations and customs, tariffs and trade barriers;
changes in non-U.S. currency exchange rates of the pound sterling, U.S. dollar, euro and currency controls;
changes in a specific country’s or region’s political or economic environment, including the implications of the United Kingdom’s withdrawal from the European Union and entrance into the Trade and Cooperation Agreement between the United Kingdom and the European Union, which remains subject to the European Union’s procedures;
trade protection measures, import or export licensing requirements or other restrictive actions by governments;
differing reimbursement regimes and price controls in certain international markets;
negative consequences from changes in tax laws;
compliance with tax, employment, immigration and labor laws for employees living or traveling abroad, including, for example, the variable tax treatment in different jurisdictions of share options granted under our employee stock plan or equity incentive plan;
workforce uncertainty in countries where labor unrest is more common than in the United States;
difficulties associated with staffing and managing international operations, including differing labor relations;
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and
business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters including earthquakes, typhoons, floods and fires.

91


 

Exchange rate fluctuations may materially affect our results of operations and financial condition.

Due to the international scope of our operations, our assets, earnings and cash flows are affected by fluctuations in the exchange rates of several currencies, particularly the U.S. dollar and pound sterling.

Additionally, although we are based primarily in the United Kingdom, we may receive payments from our business partners in U.S. dollars, Swiss francs and euros and we regularly acquire services, consumables and materials in U.S. dollars and euros. Further, any potential future revenue may be derived from the United States, countries within the euro zone and various other countries around the world. These future revenues may also be affected by fluctuations in foreign exchange rates which may, in turn, have a significant impact on our results of operations and cash flows from period to period. As a result, to the extent we continue our expansion on a global basis, we expect that increasing portions of our revenue, cost of revenue, assets and liabilities will be affected by fluctuations in currency valuations. We may, therefore, experience economic loss and a negative impact on earnings or net assets solely as a result of currency exchange rate fluctuations.

Our business and operations would suffer in the event of computer system failures, cyber-attacks or a deficiency in our, or our collaborators’ or third-party vendors’, cyber-security.

We collect, store and transmit large amounts of confidential information, including personal information, operational and financial transactions and records, clinical trial data and information relating to intellectual property, on internal information systems and through the information systems of collaborators and third-party vendors with whom we contract. Despite the implementation of security measures, these information systems are vulnerable to damage from computer viruses, malware, natural disasters, terrorism, war, telecommunication and electrical failures, cyber-attacks or cyber-intrusions over the internet or other mechanisms, attachments to emails, persons inside our organization, or persons with access to systems inside the organization. No such security measures can eliminate the possibility of the information systems’ improper functioning or the improper access or disclosure of confidential or personally identifiable information such as in the event of cyber-attacks. The risk of a security breach or disruption, particularly through cyber-attacks or cyber-intrusion, including by computer hackers, criminals, ex-U.S. governments, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased.

Additionally, outside parties may attempt to fraudulently induce employees, collaborators, or other third-party vendors to disclose sensitive information or take other actions, including making fraudulent payments or downloading malware, by using “spoofing” and “phishing” emails or other types of attacks. We have previously experienced, and in the future may experience “Phishing” attacks despite efforts to prevent and mitigate future instances. For example, in recent years we were the target of cyber-attacks comprised of phishing incidents where an immaterial unauthorized payment was made based on misrepresentations or confidential company information was inadvertently shared with an unauthorized external party. The related immaterial payment was recovered by us upon identification of the incident. The unauthorized data shared was anonymized therefore no GDPR protection regulations were breached. After an internal investigation, it was determined that no further action was required under either U.K., U.S. federal or state law. It was deemed that the cyber-attacks did not have a material impact to our business or financial condition. As a result of these incidents we, increased our cybersecurity training for all staff. While we believe we responded appropriately, including implementing remedial measures to stop this cyber-attack and with the goal of preventing similar events in the future, there can be no assurance that we will be successful in these remedial and preventative measures or successfully mitigating the effects of future cyber-attacks.

If such future events were to occur and cause interruptions in our operations, it could result in a material disruption of our clinical and research and development activities and business operations. To the extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information or making of fraudulent payments, we could incur material legal claims and liability, damage to our reputation, suffer loss or harm to our intellectual property rights, face significant financial exposure, including incurring significant costs to remediate possible injury to the affected parties and the further research, development and commercial efforts of our future mAb2 products and product candidates could be delayed.

92


 

Our employees, independent contractors, vendors, principal investigators, CROs and consultants may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading.

We are exposed to the risk that our employees, independent contractors, vendors, principal investigators, CROs and consultants may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violate the regulations of the FDA, the EMA and other comparable foreign regulatory authorities, including those laws requiring the reporting of true, complete and accurate information to such authorities; healthcare fraud and abuse laws and regulations in the United States and abroad; or laws that require the reporting of financial information or data accurately. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Activities subject to these laws also involve the improper use of information obtained in the course of clinical trials or creating fraudulent data in our preclinical studies or clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation.

 

We have adopted a code of conduct applicable to all of our employees, but it is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. Additionally, we are subject to the risk that a person could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending itself or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business, financial condition and results of operations.

Failure to comply with health and data protection laws and regulations could lead to government enforcement actions, including civil or criminal penalties, private litigation, and adverse publicity and could negatively affect our operating results and business.

We and any potential collaborators may be subject to federal, state, and foreign data protection laws and regulations, such as laws and regulations that address privacy and data security. In the United States, numerous federal and state laws and regulations, including federal health information privacy laws, state data breach notification laws, state health information privacy laws, and federal and state consumer protection laws, including Section 5 of the Federal Trade Commission Act, that govern the collection, use, disclosure and protection of health-related and other personal information could apply to our operations or the operations of our collaborators. In addition, we may obtain health information from third parties, including research institutions from which we obtain clinical trial data that are subject to privacy and security requirements under HIPAA, as amended by HITECH. Depending on the facts and circumstances, we could be subject to civil, criminal, and administrative penalties if we knowingly obtain, use, or disclose individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA.

Compliance with U.S. and international data protection laws and regulations could require us to take on more onerous obligations in our contracts, restrict our ability to collect, use and disclose data, or in some cases, impact our ability to operate in certain jurisdictions. Failure to comply with these laws and regulations could result in government enforcement actions (which could include civil, criminal and administrative penalties), private litigation, and/or adverse publicity and could negatively affect our operating results and business. Moreover, clinical trial subjects, employees and other individuals about whom we or our potential collaborators obtain personal information, as well as the providers who share this information with us, may limit our ability to collect, use and disclose the information. Claims that we have violated individuals’ privacy rights, failed to comply with data protection laws, or breached our contractual obligations, even if we are not found liable, could be expensive and time-consuming to defend and could result in adverse publicity that could harm our business.

We are subject to the U.K. Bribery Act 2010, the U.S. Foreign Corrupt Practices Act of 1977, and other anti-corruption laws, as well as export control laws, import and customs laws, trade and economic sanctions laws and other laws governing our operations.

Our operations are subject to anti-corruption laws, including the U.K. Bribery Act 2010 (the “Bribery Act”), the Foreign Corrupt Practices Act (the “FCPA”), the U.S. domestic bribery statute contained in 18 U.S.C. §201, the U.S. Travel Act and other anti-corruption laws that apply in countries where we do business. The Bribery Act, the FCPA and these other laws generally prohibit us and our employees and intermediaries from authorizing, promising, offering, or providing, directly or indirectly, a financial or other advantage to government officials or other persons to induce them to improperly perform a relevant function or activity (or reward them for such behavior).

Under the Bribery Act, we may also be liable for failing to prevent a person associated with us from committing a bribery offense. We, along with those acting on our behalf and our commercial partners, operate in a number of jurisdictions that pose a high risk of potential Bribery Act or FCPA violations, and we participate in collaborations and relationships with third parties whose corrupt or illegal activities could potentially subject us to liability under the Bribery Act, FCPA or local anti-corruption laws, even if we do not explicitly authorize or have actual knowledge of such activities. In addition, we cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be subject or the manner in which existing laws might be administered or interpreted.

Compliance with the Bribery Act, the FCPA and these other laws is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, anti-corruption laws present particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other hospital employees are considered foreign officials for purposes of the FCPA.

We are also subject to other laws and regulations governing our international operations, including regulations administered by the governments of the United Kingdom and the United States, and authorities in the European Union, including applicable export control regulations, economic sanctions and embargoes on certain countries and persons, anti-money laundering laws, import and customs requirements and currency exchange regulations, collectively referred to as the Trade Control laws.

There is no assurance that we will be completely effective in ensuring our compliance with all applicable anti-corruption laws, including the Bribery Act, the FCPA or other legal requirements, including Trade Control laws. If we are not in compliance with the Bribery Act, the FCPA and other anti-corruption laws or Trade Control laws, we may be subject to criminal and civil penalties, disgorgement and other sanctions and remedial measures, and legal expenses. Such liabilities could have an adverse impact on our business, financial condition, results of operations and liquidity. Likewise, any investigation of any potential violations of the Bribery Act, the FCPA, other anti-corruption laws or Trade Control laws could also have an adverse impact on our reputation, business, results of operations and financial condition. Further, the failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and suspension or debarment from government contracting.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemicals and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.

Although we maintain workers’ compensation insurance to cover us for costs and expenses, we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological, hazardous or radioactive materials.

Legal, political and economic uncertainty surrounding the exit of the United Kingdom from the European Union may be a source of instability in international markets, create significant currency fluctuations, adversely affect our operations in the United Kingdom and pose additional risks to our business, revenue, financial condition, and results of operations.

On June 23, 2016, the electorate in the United Kingdom voted in favor of Brexit. Thereafter, on March 29, 2017, the country formally notified the European Union of its intention to withdraw pursuant to Article 50 of the Lisbon Treaty. The withdrawal of the United Kingdom from the European Union took effect on January 31, 2020, with a transition period that ended on December 31, 2020. The United Kingdom entered into a trade agreement known as the Trade and Cooperation Agreement, which was ratified on May 1, 2021, by the European Parliament. We are continuing to evaluate the potential impacts on our business of the Trade and Cooperation Agreement. The implementation of the Trade and Cooperation Agreement, and development relating to matters not covered by the Trade and Cooperation Agreement, could lead to a period of considerable uncertainty and volatility, particularly in relation to United Kingdom financial and banking markets. Weakening of economic conditions or economic uncertainties could harm our business, and if such conditions emerge in the United Kingdom or in the rest of Europe, it may have a material adverse effect on our operations.

Currency exchange rates in the pound sterling and the euro with respect to each other and the U.S. dollar have already been adversely affected by Brexit and that may continue to be the case. In addition, the United Kingdom no longer benefits from international trade agreements negotiated by the European Union on behalf of its members, which may result in increased trade barriers which could make doing business in Europe and elsewhere more difficult. The United Kingdom has begun to enter into its own international trade agreements, and the economic impacts of those new agreements are not yet known.

We may also face new and additional regulatory costs and challenges from Brexit that could have a material adverse effect on operations. Since a significant proportion of the regulatory framework in the United Kingdom is derived from European Union directives and regulations, changes resulting from Brexit could materially impact the regulatory regime with respect to the approval of our product candidates in the United Kingdom or the European Union. Following its departure from the European Union and the expiration of the transitional period, the United Kingdom recently adopted a decentralized and mutual recognition reliance procedure for marketing authorizations that allows the United Kingdom’s clinical trial regulator, the MHRA, to consider marketing authorizations granted in the European Union or the three additional European Economic Area countries. However, additional requests for information may arise and additional time may be required with respect to applications for marketing authorizations in the United Kingdom using these procedures. Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, would prevent us from commercializing product candidates in the United Kingdom and/or the European Union and restrict our ability to generate revenue and achieve and sustain profitability. If any of these outcomes occur, we may be forced to restrict or delay efforts to seek regulatory approval in the United Kingdom and/or European Union for our product candidates, which could significantly and materially harm our business.

Factors that could cause or contribute to such differences include, but are not limited to, those discussed in Item 1A, “Risk Factors” of this Annual Report on Form 10-K.

Overview

F-star Therapeutics Inc (collectively with its subsidiaries, (“we") is a clinical-stage biopharmaceutical company dedicated to developing next generation immunotherapies to transform the lives of patients with cancer. We are pioneering the use of tetravalent (2+2) bispecific antibodies to create a paradigm shift in cancer therapy. We have four second generation IO therapeutics in the clinic, each directed against some of the most promising IO targets in drug development, including LAG-3 and CD137. Our proprietary antibody discovery platform is protected by an extensive intellectual property estate. We have over 500 granted patents and pending patent applications relating to our platform technology and product pipeline. We have attracted multiple partnerships with biotechnology and pharmaceutical companies targeting significant unmet needs across several disease areas, including oncology, immunology, and indications affecting the CNS with over 20 programs, based on our technology, being developed by our partners. Our goal is to offer patients better and more durable benefits than currently available immuno-oncology treatments by developing medicines that seek to block tumor immune evasion. Through our proprietary tetravalent, bispecific natural antibody (mAb²) format, our mission is to generate highly differentiated medicines with monoclonal antibody-like manufacturability, good safety and tolerability. With four distinct binding sites in a natural human antibody format, we believe our proprietary technology will overcome many of the challenges facing current immuno-oncology therapies, including other bispecific formats, due to the strong pharmacology enabled by tetravalent bispecific binding.

 

Our most advanced product candidate, FS118, is currently being evaluated in proof-of-concept Phase 2 trials in PD-1/PD-L1 acquired resistance head and neck cancer patients and in CPI, NSCLC, and DLBCL patients. FS118 is a tetravalent mAb2 bispecific antibody targeting two receptors, PD-L1 and LAG-3, both of which are clinically validated targets in immuno-oncology. Phase 1 data from 43 heavily pre-treated patients with advanced cancer, who have failed PD-1/PD-L1 therapy, showed that administration of FS118 was well-tolerated with no dose limiting toxicities up to 20 mg/kg. In addition, a DCR, defined as either a complete response, partial response or stable disease, of 49% (19 out of 39) was observed in patients receiving dose levels of FS118 of 1mg/kg or greater. In acquired resistance patients, DCR was 55 % (17 out of 31 patients) in patients receiving 1 mg/kg or greater and long term (more than six months) disease control was observed in six of these patients. We expect to provide an update from the proof-of-concept Phase 2 trial in PD-1/PD-L1 acquired resistance head and neck cancer patients in mid-2022. Data reported during the first half of 2021, from a randomized phase 3 trial conducted by another company in patients with previously untreated, locally advanced or metastatic melanoma provides clinical validation for the combination of LAG-3 and PD-1 inhibition. This clinical benefit in targeting PD-1 and LAG-3 gives us reason to believe that FS118 has potential to benefit patients not only with acquired resistance, but also in preventing resistance in patients receiving PD-1 monotherapy for the first time. With respect to the latter, we initiated a clinical trial of FS118 in CPI-naïve patients in biomarker enriched NSCLC and DLBCL populations in late 2021.

 

Our second product candidate, FS222, aims to improve outcomes particularly in patients with tumors that express low levels of PD-L1 and is a mAb2 bispecific antibody that is designed to target both the costimulatory CD137 receptor and the inhibitory PD-L1 ligand, which are co-expressed in many tumor types. The Phase 1 clinical trial evaluating FS222 in patients with advanced cancers is ongoing. We believe there is a strong rationale to combine FS222 with other anti-cancer agents, and this can be done within the Phase 1 trial. The accelerated dose titration was completed in the second half of 2021, and identification of optimal patient groups, dose and schedule is on-going. We expect to provide an update on the progress of the phase 1 trial in mid-2022 and report safety, biomarker, and preliminary efficacy data in the second half of 2022.

 

Our third product candidate, FS120, aims to improve checkpoint inhibitor and chemotherapy outcomes and is a mAb2 bispecific antibody that is designed to bind to and stimulate OX40 and CD137, two proteins found on the surface of T cells that both function to enhance T cell activity. We are developing FS120 alone and in combination with PD-1 therapy for the treatment of tumors where PD-1 inhibitors are approved, and which have been associated with co-expression of OX40 and

99


 

CD137 in the tumor microenvironment. The Phase 1 clinical trial in patients with advanced cancers is ongoing and we completed the accelerated dose titration phase during the second half of 2021. We are continuing further dose escalation to determine an optimal dosing regimen to initiate a combination of FS120 and the PD-1 inhibitor, pembrolizumab, in the second half of 2022. Pembrolizumab will be supplied under a clinical trial collaboration and supply agreement with Merck & Co.

 

SB 11285, which F-star acquired pursuant the business combination with Spring Bank, is a next generation cyclic dinucleotide STimulator of INterferon Gene (“STING”) agonist designed to improve checkpoint inhibition outcomes as an immunotherapeutic compound for the treatment of selected cancers. SB 11285 has appeared to be well tolerated both alone and in combination with atezolizumab across all dose levels tested to-date, including five dose levels as monotherapy and three dose levels as a combination. Initial analysis showed that PK were in-line with the predicted profile for rapid cellular uptake, a characteristic of second generation STING agonists. We are continuing with further dose-escalation and in parallel pursuing strategic business development opportunities for SB 11285. We expect to report an update on this trial in the second half of 2022.

Share Exchange Agreement

On November 20, 2020, we, completed our business combination (the “Transaction”) with F-star Therapeutics Limited (“F-star Ltd”) in accordance with the terms of the Share Exchange Agreement, dated July 29, 2020 (the “Exchange Agreement”), by and among us, F-star Ltd and the holders of issued shares in the capital stock of F-star Ltd and the holders of convertible notes of F-star Ltd each as set forth therein (each a “Seller”, and collectively with holders of F-star Ltd securities who subsequently became parties to the Exchange Agreement, the “Sellers”). Pursuant to the Exchange Agreement, each ordinary share of F-star Ltd outstanding immediately prior to the closing of the Transaction (the “Closing”) was exchanged by the Seller that owns such F-star Ltd shares for such number of duly authorized, validly issued, fully paid and non-assessable shares of Company common stock as is equal to the exchange ratio formula determined pursuant to the Exchange Agreement (the “Exchange Ratio”), rounded to the nearest whole share of Company common stock (after aggregating all fractional shares of Company common stock issuable to such Seller). Also, on November 20, 2020, in connection with, and prior to completion of, the Transaction, Spring Bank effected a 1-for-4 reverse stock split of its common stock (the “Reverse Stock Split”) and, following the completion of the Transaction, changed its name to F-star Therapeutics, Inc. Unless otherwise noted, all references to share amounts in this report reflect the Reverse Stock Split.

Under the terms of the Exchange Agreement, at the Closing, Spring Bank issued an aggregate of 4,620,618 shares of its common stock to F-star Ltd stockholders, based on an exchange ratio of 0.1125 shares of the Company’s common stock for each F-star Ltd ordinary share, stock option and RSU outstanding immediately prior to the Closing. The exchange ratio was determined through arms-length negotiations between Spring Bank and F-star Ltd pursuant to a formula set forth in the Exchange Agreement.

Pursuant to the Exchange Agreement, immediately prior to the Closing, certain investors in F-star Ltd purchased $15.0 million of F-star Ltd ordinary shares (the “Pre-Closing Financing”). These ordinary shares of F-star Ltd were then exchanged at the Closing for shares of the Company’s common stock in the Transaction at the same exchange rate.

Immediately, following the Reverse Stock Split and the Closing, there were approximately 4,449,559 shares of Spring Bank common stock outstanding. Following the Closing, the F-star Ltd stockholders beneficially owned approximately 53.7% of the combined Company’s common stock and the existing stockholders of Spring Bank beneficially owned approximately 46.3% of our common stock outstanding. Concurrently with the execution of the Exchange Agreement, certain officers and directors of Spring Bank and F-star Ltd and certain stockholders of F-star Ltd entered into lock-up agreements (the “Lock-up Agreements”), pursuant to which they agreed to certain restrictions on transfers of any shares of our common stock for the 180-day period following the Closing, other than the shares of the Company’s common stock received in exchange for ordinary shares of F-star Ltd subscribed for in the Pre-Closing Financing and pursuant to certain other limited exceptions.

In addition, at the Closing, Spring Bank, F-star Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, entered into a STING Agonist Contingent Value Rights Agreement (the “STING Agonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Agonist CVR Agreement, each pre-Reverse Stock Split share of Company common stock held by stockholders as of the record date on November 19, 2020, immediately prior to the Closing, received a dividend of one contingent value right (“STING Agonist CVR”), payable on a pre-Reverse Stock Split basis, entitling such holders to receive, in connection with certain transactions

100


 

involving SB 11285 occurring on or prior to the STING Agonist CVR Expiration Date (as defined below) that result in aggregate Net Proceeds (as defined in the STING Agonist CVR Agreement) at least equal to the Target Payment Amount (as defined below): an aggregate amount equal to the greater of (i) 25% of the Net Proceeds received from all CVR Transactions (as defined in the STING Agonist CVR Agreement) and (ii) an aggregate amount equal to the product of $1.00 and the total number of shares of Company common stock outstanding as of such record date (not to exceed an aggregate amount of $18.0 million) (the “Target Payment Amount”).

The CVR payment obligation expires on the later of 18 months following the Closing or the one-year anniversary of the date of the final database lock of our current STING clinical trial (as defined in the STING Agonist CVR Agreement) (the “STING Agonist CVR Expiration Date”). The STING Agonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest and are not registered with the SEC or listed for trading on any exchange. Until the STING Agonist CVR Expiration Date, subject to certain exceptions, the we are required to use commercially reasonable efforts to (a) complete the STING Trial and (b) pursue a CVR Transaction. Unless terminated earlier in accordance with its terms, the STING Agonist CVR Agreement became effective upon the Closing will continue in effect until the STING Agonist CVR Expiration Date the payment or all CVR payment amounts are paid pursuant to its terms.

At the Closing, Spring Bank, F-star Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, also entered into a STING Antagonist Contingent Value Rights Agreement (the “STING Antagonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Antagonist CVR Agreement, each share of common stock held by stockholders as of November 19, 2020, immediately prior to the Closing, received a dividend of one contingent value right (“STING Antagonist CVR”) entitling such holders to receive, in connection with the execution of a potential development agreement (the “Approved Development Agreement”) and certain other transactions involving proprietary STING antagonist compound occurring on or prior to the STING Antagonist CVR Expiration Date (as defined below) equal to: 80% of all net proceeds (as defined in the STING Antagonist CVR Agreement) received by us after the Closing pursuant to (i) the Approved Development Agreement, if any, and (ii) all CVR Transactions (as defined in the STING Antagonist CVR Agreement) entered into prior to the STING Antagonist CVR Expiration Date (as defined below).

The CVR payment obligations expire on the seventh anniversary of the Closing (the “STING Antagonist CVR Expiration Date”). The STING Antagonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest and are not registered with the SEC or listed for trading on any exchange. Until the STING Antagonist CVR Expiration Date, subject to certain exceptions, we are required to use commercially reasonable efforts to (a) consummate the Approved Development Agreement to the extent not entered into prior to Closing, (b) to perform the terms of the Approved Development Agreement and (c) pursue CVR Transactions. Unless terminated earlier in accordance with its terms, the STING Antagonist CVR Agreement became effective upon the Closing and will continue in effect until the STING Antagonist CVR Expiration Date or all CVR payment amounts are paid pursuant to its terms.

The acquisition-date fair value of the contingent valuation rights liability represents the future payments that are contingent upon the achievement of sale or licencing for the product candidates. The fair value of the contingent consideration acquired of $3.6million and $2.5 million as of December 31, 2021 and December 31, 2020 respectively is based on our probability-weighted discounted cash flow assessment that considers probability and timing of future payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving a sale or licensing agreement, anticipated timelines and discount rate. Changes in the fair value of the liability will be recognized in the consolidated statement of operations and comprehensive loss until settlement.

Our common stock, which was listed on the Nasdaq Capital Market, traded through the close of business on Friday, November 20, 2020 under the ticker symbol “SBPH” and continued trading on the Nasdaq Capital Market, on a post-Reverse Stock Split adjusted basis, under the ticker symbol “FSTX” beginning on Monday, November 23, 2020. Commencing on November 23, 2020, our common stock was represented by a new CUSIP number, 30315R 107. The combined company is now based out of F-star's facilities in Cambridge, U.K. and in Cambridge, Massachusetts.

The Transaction was accounted for as a business combination using the acquisition method of accounting under the provisions of Financial Accounting Standards Board, Accounting Standards Codification (“ASC 805”), Topic 805 “Business Combinations” (“ASC 805”). The Transaction was accounted for as a reverse acquisition with F-star Ltd being deemed the

101


 

acquiring company for accounting purposes. Under ASC 805, F-star Ltd as the accounting acquirer, recorded the assets acquired and liabilities assumed of Spring Bank in the Transaction at their fair values as of the acquisition date (Note 4 of the financial statements).

F-star Ltd was determined to be the accounting acquirer based on an analysis of the criteria outlined in ASC 805 and the facts and circumstances specific to the Transaction, including the fact that immediately following the Transaction: (1) F-star Ltd shareholders owned the majority of the voting rights of the combined company; (2) F-star Ltd designated a majority (five of eight) of the initial members of the board of directors of the combined company; and (3) F-star Ltd senior management held the key positions in senior management of the combined company. As a result, upon consummation of the Transaction, the historical financial statements of F-star Ltd became the historical financial statements of the combined organization.

Impact of COVID-19 on our Business

The continued spread of the COVID-19 pandemic has been evolving, and to date has led to the implementation of various responses, including government-imposed quarantines, travel restrictions and other public health safety measures.

Management continues to closely monitor the impact of the COVID-19 pandemic on all aspects of the business, including how it will impact operations and the operations of customers, vendors, and business partners. The extent to which COVID-19 impacts the future business, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence at this time, such as new information that may emerge concerning the emergence or severity of other strains of COVID-19 or the effectiveness of actions to vaccinate against or contain COVID-19 or treat its impact, among others. If we or any of the third parties with which it engages, however, were to experience shutdowns or other business disruptions, the ability to conduct business in the manner and on the timelines presently planned could be materially and negatively affected, which could have a material adverse impact on business, results of operations and financial condition. The estimates of the impact on our business may change based on new information that may emerge concerning COVID-19 and the actions to contain it or treat its impact and the economic impact on local, regional, national, and international markets.

Management have not identified any triggering events which would result in any significant impairment losses in the carrying values of assets as a result of the pandemic and are not aware of any specific related event or circumstance that would require management to revise estimates reflected in our consolidated financial statements.

Financial Operations Overview

License revenue

To date, we have not generated any revenue from product sales, and we do not expect to generate any revenue from product sales for the foreseeable future. Our revenue consists of collaboration revenue under our license and collaboration agreements with Ares, Denali, AstraZeneca, Janssen and others, including amounts that are recognized related to upfront payments, milestone payments, option exercise payments, and amounts due to us for research and development services. In the future, revenue may include new collaboration agreements, additional milestone payments, option exercise payments, and royalties on any net product sales under our collaborations. We expect that any revenue we generate will fluctuate from period to period as a result of the timing and amount of license, research and development services, and milestone and other payments.

Operating Expenses

Research and development costs

Research and development costs are expensed as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries, share-based compensation expense and benefits, facilities costs and laboratory supplies, depreciation, amortization and impairment expense, manufacturing expenses and external costs of outside vendors engaged to conduct preclinical development activities and clinical trials as well as the cost of licensing technology. Typically, upfront payments and milestone payments made for the licensing of technology are expensed as research and development in the period in which they are incurred, except for payments relating to intellectual property rights with future alternative use which will be expensed when the intellectual property is in use. Non-refundable advance payments for goods or services to be received in the future for use in research and development activities are

102


 

recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed.

Those expenses associated with R&D and clinical costs primarily include:

expenses incurred under agreements with CROs as well as investigative sites and consultants that conduct our clinical trials, preclinical studies and other scientific development services;
manufacturing scale-up expenses and the cost of acquiring and manufacturing preclinical and clinical trial materials;
expenses incurred for outsourced professional scientific development services;
costs for laboratory materials and supplies used to support our research activities;
allocated facilities costs, depreciation, and other expenses, which include rent and utilities;
up-front, milestone and management fees for maintaining licenses under our third-party licensing agreement; and
compensation related expenses

We recognize external R&D costs based on an evaluation of the progress to completion of specific tasks using information provided to it by its internal program managers and service providers.

Research and development activities are central to the our business models. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later stage clinical trials. As a result, we expect that research and development expenses will increase over the next several years as we increase personnel costs, initiate and conducts additional clinical trials and prepare regulatory filings related to the various product candidates.

General and administrative expenses

General and administrative expenses consist primarily of salaries, related benefits, travel, and share-based compensation expense for personnel in executive, finance, legal and administrative functions. General and administrative expenses also include facility-related costs, patent filing and prosecution costs, insurance and marketing costs and professional fees for legal, consulting, accounting, audit, tax services and costs associated with being a public company. Other expense also includes foreign currency transaction losses. We expect that general and administrative expenses will increase in the future as we expand our operating activities and incur the costs of being a public reporting company in the United States.

Other income and expenses, net

Other income and expenses, net, is primarily rent received from subletting an office in the United States and interest received on overdue trade receivable balances, bank interest received, and interest expense, which is primarily bank interest payable and similar charges, the interest liability on leased assets and convertible debt notes, and foreign exchange losses incurred. Foreign exchange gain (loss) is foreign exchange gains or losses due to the fluctuation of GBP, U.S. dollar and the Euro. Change in the fair value of convertible debt is the fair value adjustment of the convertible notes as measured using level 3 inputs.

Benefits from income tax

For the years ended December 31, 2021, and 2020, we were subject to corporate taxation in the United States, United Kingdom and Austria.

The UK-established entities have generated losses and some profits in the United Kingdom since inception and have therefore not paid significant United Kingdom corporation tax. F-star GmbH has historical losses in Austria with more recent profits, which resulted in payment of Austrian corporation tax in the period ended December 31, 2020 and none in the period ended December 31, 2021. The corporation tax benefit/ (tax) presented in the our statements of comprehensive income/(loss) represents the tax impact from its operating activities in the United States, United Kingdom and Austria, which has generated

103


 

taxable income in certain periods. As the entities located in the United Kingdom carry out extensive research and development activities, they seek to benefit from the United Kingdom research and development tax credit cash rebate regime: The Small and Medium-sized Enterprises R&D Tax Credit Program (“SME Program”). Qualifying expenditures largely comprise employment costs for research staff, consumables expenses incurred under agreements with third parties that conduct research and development, preclinical activities, clinical activities and manufacturing on our behalf and certain internal overhead costs incurred as part of research projects. No research and development activities are carried out in Austria and so we are not able to utilize the research and development premium available under the Austrian corporation tax regime.

The Small and Medium-sized Enterprises research and development tax credit received in the United Kingdom permits companies to deduct an extra 130% of their qualifying costs from their yearly profit or loss, as well as the normal 100% deduction, to make a total 230% deduction. If the company is loss making it is entitled to claim a tax credit worth up to 14.5% of the surrenderable loss. To qualify for SME research & development relief companies are required to employ fewer than 500 staff and have revenue under €100.0 million or a balance sheet total of less than €86.0 million.

The U.K. Government has released draft legislation to introduce a cap on the amount of the payable credit that a qualifying loss-making SME business can receive through R&D relief in any one year. The cap would be applied to restrict payable credit claims in excess of £20,000 with effect for accounting periods beginning on or after April 2021 by reference to, broadly, three times our total employee payroll tax and social security liabilities. The draft legislation also contains an exemption which prevents the cap from applying. That exemption requires the company to be creating, or taking steps to create, intellectual property as well as having research and development expenditure in respect of connected parties which does not exceed 15% of the total claimed. We do not expect this legislation if adopted to have a material impact on its payable credit claims based on amounts currently claimed.

Research and development tax credits received in the U.K. are recorded as a reduction to research and development expenses. The U.K. research and development tax credit is payable to us after surrendering tax losses and is not dependent on current or future taxable income. As a result, it is not reflected as part of the income tax provision. If, in the future, any U.K. research and development tax credits generated are utilized to offset a corporate income tax liability in the U.K., that portion would be recorded as a benefit within the income tax provision and any refundable portion not dependent on taxable income would continue to be recorded as a reduction to research and development expenses.

Income tax benefit increased by $0.4 million from a tax benefit of $0.0 million to a tax benefit of $0.4 million in the year ended December 31, 2021. This increase is due to a $0.6 million tax benefit due to a decrease in the deferred tax liability in the year ended December 31, 2020, offset by an increase in federal and state tax charges of $0.2 million.

In the event that we generate revenues in the future, we may benefit from the United Kingdom “patent box” regime that allows profits attributable to revenues from patents or patented products to be taxed at an effective rate of 10%.

Value Added Tax (“VAT”) is broadly charged on all taxable supplies of goods and services by VAT-registered businesses. In the United Kingdom, under current rates, an amount of 20% of the value, as determined for VAT purposes, of the goods or services supplied is added to all sales invoices and is payable to the UK’s tax authority, HMRC. Similarly, VAT paid on purchase invoices is generally reclaimable from HMRC. In Austria, under current rates, an amount of 20% of the value, as determined for VAT purposes, of the goods or services supplied is added to all sales invoices and is payable to the Austrian tax authority. Similarly, VAT paid on purchase invoices is generally reclaimable from the Austrian tax authority.

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of our consolidated financial statements and related disclosures requires our management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenue, costs and expenses and related disclosures. We believe that the estimates and assumptions underlying the accounting policies described therein may have the greatest potential impact on our consolidated financial statements and, therefore, consider these to be our critical accounting policies. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these current estimates based on different assumptions and under different conditions.

104


 

While our significant accounting policies are described in greater detail in Note 2 to our consolidated financial statements appearing elsewhere in the Annual Report on Form 10-K, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our consolidated financial statements

Licensing and Collaboration Revenues

Our revenues are generated primarily through license and collaboration agreements with pharmaceutical and biotechnology companies. The terms of these arrangements may include (i) the grant of intellectual property rights (IP licenses) to therapeutic drug candidates against specified targets, developed using our proprietary mAb2 bispecific antibody platform, (ii) performing research and development services to optimize the drug candidates, and (iii) the grant of options to obtain additional research and development services or licenses for additional targets, or to optimize product candidates, upon the payment of option fees.

The terms of these arrangements typically include payment to us of one or more of the following: non-refundable, upfront license fees; payments for research and development services; fees upon the exercise of options to obtain additional services or licenses; payments based upon the achievement of defined collaboration objectives; future regulatory and sales-based milestone payments; and royalties on net sales of future products.

We recognize revenue in accordance with ASU 2014-09, Revenue from Contracts with Customers (Topic 606) or

ASC 606, and all subsequent amendments. This standard applies to all contracts with customers, except for contracts that

are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments.

Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized under ASC 606, we perform the following steps:

(i)
identify the promised goods or services in the contract;
(ii)
determine whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract;
(iii)
measurement of the transaction price, including the constraint on variable consideration;
(iv)
allocation of the transaction price to the performance obligations; and
(v)
recognition of revenue when (or as) we satisfy each performance obligation.

As part of the accounting for these arrangements, we must make significant judgments, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each performance obligation.

Once a contract is determined to be within the scope of ASC 606, we assess the goods or services promised within the contract and determines those that are performance obligations. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. We assess if these options provide a material right to the customer and if so, they are considered performance obligations.

Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the customer. The promised goods or services in our contracts with customers primarily consist of license rights to our intellectual property for research and development, research and development services, options to acquire additional research and development services, and options to obtain additional licenses, such as a commercialization license for a potential product candidate. Promised goods or services are considered distinct when:

(i)
the customer can benefit from the good or service on its own or together with other readily available resources; and
(ii)
the promised good or service is separately identifiable from other promises in the contract.

In assessing whether promised goods or services are distinct, we consider factors such as the stage of development of the underlying intellectual property, the capabilities of the customer to develop the intellectual property on their own and whether the required expertise is readily available. In addition, we consider whether the collaboration partner can benefit from a

105


 

promise for its intended purpose without the receipt of the remaining promises, whether the value of the promise is dependent on the unsatisfied promises, whether there are other vendors that could provide the remaining promises, and whether it is separately identifiable from the remaining promises. We estimate the transaction price based on the amount of consideration the Company expects to receive for transferring the promised goods or services in the contract. The consideration may include both fixed consideration and variable consideration. At the inception of each arrangement that includes variable consideration, we evaluate the amount of the potential payments and the likelihood that the payments will be received. We utilize either the most likely amount method or expected value method to estimate variable consideration to include in the transaction price based on which method better predicts the amount of consideration expected to be received. The amount included in the transaction price is constrained to the amount for which it is probable that a significant reversal of cumulative revenue recognized will not occur. At the end of each subsequent reporting period, we re-evaluate the estimated variable consideration included in the transaction price and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis in the period of adjustment.

After the transaction price is determined it is allocated to the identified performance obligations based on the estimated standalone selling price. We must develop assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. We utilize key assumptions to determine the standalone selling price, which may include other comparable transactions, pricing considered in negotiating the transaction, probabilities of technical and regulatory success and the estimated costs. Certain variable consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated to each performance obligation are consistent with the amounts we would expect to receive for each performance obligation.

We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time based on the use of an input method.

We account for contract modifications as a separate contract if both of the following conditions are met:

(i)
the scope of the contract increases because of the addition of promised goods or services that are distinct; and
(ii)
the price of the contract increases by an amount of consideration that reflects standalone selling prices of the additional promised goods or services and any appropriate adjustments to that price to reflect the circumstances of the particular contract.

If a contract modification is deemed to not be a separate contract, then the transaction price is updated and allocated to the remaining performance obligations (both from the existing contract and the modification). Previously recognized revenue for goods and services that are not distinct from the modified goods or services is adjusted based upon an updated measure of progress for the partially satisfied performance obligations.

If a contract modification is deemed to be a separate contract, any revenue recognized under the original contract is not retrospectively adjusted and any performance obligations remaining under the original contract continue to be recognized under the terms of that contract.

Our collaboration revenue arrangements include the following:

Up-front License Fees: If a license is determined to be distinct from the other performance obligations identified in the arrangement, we recognize revenues from nonrefundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. We evaluate the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone payments: Our collaboration agreements may include development and regulatory milestones. We evaluate whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. We evaluate factors such as the scientific, clinical, regulatory, commercial, and

106


 

other risks that must be overcome to achieve the particular milestone in making this assessment. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our control or the licensee’s control, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. At the end of each reporting period, we re-evaluate the probability of achievement of such milestones and any related constraint, and if necessary, adjusts the estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect collaboration revenue and net loss in the period of adjustment.

Customer Options: We evaluate the customer options to obtain additional items (i.e., additional license rights) for material rights, or options to acquire additional goods or services for free or at a discount. Optional future services that reflect our standalone selling prices do not provide the customer with a material right and, therefore, are not considered performance obligations and are accounted for as separate contracts. If optional future services include a material right, they are accounted for as performance obligations. We determine an estimated standalone selling price of any material rights for the purpose of allocating the transaction price. We consider factors such as the identified discount and the probability that the customer will exercise the option. Amounts allocated to a material right are not recognized as revenue until, at the earliest, the option is exercised or expires.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on a level of sales, and the license is deemed to be the predominant item to which the royalties relate, we will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, we have not recognized any revenue related to sales-based royalties or milestone payments based on the level of sales.

Research and Development Services: The promises under our collaboration agreements may include research and development services to be performed by us on behalf of the partner. Payments or reimbursements resulting from our research and development efforts are recognized as the services are performed and presented on a gross basis because we are the principal for such efforts.

Accrued Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel and CROs to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our research and development service providers invoice us in arrears for services performed, on a predetermined schedule or when contractual milestones are met; however, some require advanced payments. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid to:

CROs in connection with performing research services on our behalf and clinical trials;
investigative sites or other providers in connection with clinical trials;
vendors in connection with preclinical and clinical development activities; and
vendors related to product manufacturing, development and distribution of preclinical and clinical material and supplies.

We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and efforts expended pursuant to quotes and contracts with multiple CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the pre-clinical and clinical expenses. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed, enrollment of patients, number of sites activated and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies

107


 

from our estimate, we adjust the accrual or amount of prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too low in any particular period. To date, we have not made any material adjustments to our prior estimates of accrued research and development expenses.

Contingent value rights

The fair value of the contingent value rights is based on our probability-weighted discounted cash flow assessment that considers probability and timing of future payments in relation to the achievement of a sale or licensing arrangement for the STING product candidates, or the achievement of future development, regulatory and sales-based milestones in existing agreements. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving a sale, licensing agreement or milestone, anticipated timelines, and discount rate. Changes in the fair value of the liability will be recognized in the consolidated statement of operations and comprehensive loss until settlement.

Share-based compensation

We account for share-based compensation in accordance with ASC 718, ‘Compensation – "Stock Compensation” (“ASC 718”). ASC 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service period in our consolidated statements of operations and comprehensive loss.

We record the expense for option awards using a graded vesting method. We account for forfeitures as they occur. For share-based awards granted to non-employee consultants, the measurement date is the date of grant. The compensation expense is then recognized over the requisite service period, which is the vesting period of the respective award.

The fair value of stock options (“options”) on the grant date is estimated using the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including the option’s expected term and the price volatility of the underlying stock, to determine the fair value of the award.

Historically given the absence of an active market for the ordinary shares of F-star Ltd, the board of directors determined the estimated fair value of our equity instruments based on input from management, which utilized the most recently available independent third-party valuation, and considering a number of objective and subjective factors, including external market conditions affecting the biotechnology industry sector. Each valuation methodology includes estimates and assumptions that require judgment. These estimates and assumptions include a number of objective and subjective factors in determining the value of F-star Ltd ordinary shares at each grant date. The expected volatility for F-star Ltd was calculated based on reported volatility data for a representative group of publicly traded companies for which historical information was available. The historical volatility is calculated based on a period of time commensurate with the assumption used for the expected term. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption. F-star Ltd used the simplified method, under which the expected term is presumed to be the midpoint between the vesting date and the end of the contractual term. F-star Ltd utilized this method due to the lack of historical exercise data and the plain nature of its share-based awards.

We use the remaining contractual term for the expected life of non-employee awards. The expected dividend yield is assumed to be zero as we have never paid dividends and has no current plans to pay any dividends.

We classify share-based compensation expense in our consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

License Revenue

Revenue for the year ended December 31, 2021 was $21.2 million , compared with $11.3 million for the year ended December 31, 2020. The increase of approximately $9.9 million was primarily due to the following:-

 

Revenue of $18.3 million was generated from upfront fees on new licensing agreements (including Janssen and AstraZeneca) in the year ended December 31, 2021. The remaining $2.9 million was primarily generated from Ares' exercise of their option to license the third molecule for which a license was granted under the 2020 License and Collaboration Agreement ("2020 LCA").

 

In the year ended December 31, 2020, revenue of $11.3 million consisted of $9.9 million related to licensing and R&D services provided to Ares in relation to the second molecule included in the 2020 LCA, and $1.3 million to Denali in relation to the second accepted Fcab target included in the Denali License and Collaboration Agreement.

Costs related to research and development for the year ended December 31, 2021 increased by approximately $14.6 million to $28.8 million from $14.1 million in the year ended December 31, 2020.

109


 

This $14.6 million increase for the year ended December 31, 2021, was primarily due to an increase in clinical CRO and clinical assay costs of $7.3 million, due to the expansion of our FS118 clinical trial into acquired resistance head and neck patients and CPI naive trial in NSCLC and DLBCL, the mono and combo SB11275 clinical trial which was acquired in the transaction with Spring Bank in November 2020, and continued progression of our FS120 and FS222 clinical programs. In addition, there was an increase of $3.2 million in manufacturing costs, $1.2 million in R&D staff costs, $1.0 million in share-based compensation expense, $0.7 million in laboratory consumables, $0.2 million in other costs and a $1.0 million decrease in the UK R&D tax incentive credit (which is recorded as a credit against R&D costs).

General and administrative expense

General and administrative expense for the year ended December 31, 2021 increased by approximately $3.6 million to $23.1 million from $19.5 million for the year ended December 31, 2020. The increase was primarily due to an increase of $2.4 million in stock based compensation expense due to new stock option grants in 2020 and 2021, an increase in director and officer insurance costs of $1.6 million as a result of becoming a public company in November 2020, an increase in facilities and IT costs of $1.0 million, mainly due to $0.6 million of facilities costs primarily associated with the two Spring Bank building leases we assumed in November 2020 (offsetting sublease income is recorded in other income) and $0.4 million for the implementation of new quality management software during the fourth quarter of 2021. These increases were offset by decreases in legal and professional fees of $0.8 million due to the costs recorded in the prior year associated with the November 20, 2020 Share Exchange Agreement transaction and a decrease in general and administrative staff costs of $0.6 million.

Other income (expense), net for the year ended December 31, 2021 consisted of net other income of $1.2 million compared with net other income of $0.1 million for the year ended December 31, 2020, for an increase of $1.1 million additional net income. This increase is primarily due to a $1.0 million increase in foreign exchange gains, an increase in sublease income of $0.6 million due to sublease income being acquired with Spring Bank in November 2021, offset by a decrease of $0.5 million in income under the UK Coronavirus Job Retention Scheme income, as this scheme ended on September 30, 2021.

 

In the current period, interest expense of $0.8 million relates to term debt that was drawn down in two tranches, in April and June 2021. Interest expense of $1.0 million in the prior period related to the accrued interest on convertible notes, which were converted to equity in November 2020.

During the year ended December 31, 2021 the fair value loss of $1.3 million was due to updated assumptions in the Level 3 inputs included in the valuation model of the contingent value rights liability. In the year ended December 31, 2020 a loss of $2.4 million was incurred in relation to fair value movements in convertible notes, which were converted to equity in November 2020.

Liquidity and Capital Resources

Sources of liquidity

From our inception through December 31, 2021, we have not generated any revenue from product sales, and we have incurred significant operating losses and negative cash flows from our operations. We do not expect to generate significant revenue from sales of any products for several years, if at all.

110


 

At December 31, 2021, we had working capital (current assets less current liabilities) of $72.6 million, an accumulated deficit of $78.5 million, cash of $78.5 million and accounts payable and accrued expenses of $ 9.3 million. Our future success is dependent on our ability to successfully obtain additional working capital, obtain regulatory approval for and successfully launch and commercialize our product candidates and to ultimately attain profitable operations.

Historically, we have financed our operations primarily with proceeds from the issuance of common and convertible preferred shares, proceeds from issuances in connection with a convertible note facility, proceeds received from upfront payments and development milestone payments in connection with our collaboration arrangements, and payments received for research and development services and term debt. We expect this historical financing trend to continue if and until we are able to obtain regulatory approval for and successfully commercialize one or more of our drug candidates, although there can be no assurance that we will obtain regulatory approval or successfully commercialize any of our current or planned future drug product candidates.

Operating activities

Net cash used of $27.3 million in operating activities for the year ended December 31, 2021 consisted of the net loss of $31.3 million adjusted for changes in our operating assets and liabilities of $4.7 million and non-cash charges of $8.9 million, which primarily included share-based compensation expense of $6.9 million, interest expense of $0.1 million, depreciation and amortization of $0.6 million, changes in the fair value of the contingent value rights liability of $1.3 million. The remaining $0.3 million relates to a payment that was made to contingent value rights holders.

Net cash used of $16.2 million in operating activities for the year ended December 31, 2020 was primarily due to a net loss of $24.6 million adjusted for changes in operating assets and liabilities of $1.0 million and non-cash charges of $8.4 million. The non-cash charges included share-based compensation expense of $3.5 million, foreign exchange losses of $0.4 million, depreciation of $1.1 million, non-cash interest expense of $1.0 million relating to the convertible notes and changes in fair value of convertible notes of $2.4 million.

Investing activities

For the year ended December 31, 2021 cash used in investing activities of $0.6 million related solely to the purchase of property, plant and equipment.

$14.0 million of cash provided from investing activities for the year ended December 31, 2020 primarily consisted of $9.8 million of cash acquired on execution of the Share Exchange agreement on November 20, 2020, $5.0 million on sale of marketable securities, offset by $0.7 million for the purchase of certain intangible assets.

Financing activities

During the year ended December 31, 2021, net cash provided by financing activities was $88.1 million. This included $78.3 million raised from the issue of common stock, of which $68.7 million was generated from underwritten public offering, and $10.4 million was generated from our ATM or “at the market” offering, offset by $0.8 million in transaction expense and fees in connection with the offering. In addition, net proceeds of $9.9 million were received under the Loan and Security Agreement with Horizon and third-party debt issuance costs of $0.1 million were paid.

During the year ended December 31, 2020 net cash provided by financing activities of $15.9 million was primarily related to $15.0 million received from a private placement of common stock and $0.9 million in proceeds from the issuance of convertible notes in F-star Ltd.

Funding Requirements

Going Concern

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The accompanying financial statements do not reflect any adjustments relating to the recoverability and reclassifications of assets and liabilities that might be necessary if we are unable to continue as a going concern. We expect our costs and expenses to increase as we continue to develop our product candidates and progress our current clinical programs and costs associated with being a public company.

Pursuant to the requirements of Accounting Standard Codification (ASC) 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements are issued. This evaluation initially did not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date of the financial statements included elsewhere in this Annual Report on Form 10-K, and the probability of such mitigating plans being effectively implemented, and if implemented, the probability that such mitigating plans will mitigate the substantial doubt about the entity’s ability to continue as a going concern for the one year after the date the financials statements included elsewhere in this Annual Report on Form 10-K are issued. Certain elements of our operating plan to alleviate the conditions that raise substantial doubt are outside of our control and cannot be included in management’s evaluation under the requirements of Accounting Standard Codification (ASC) 205-40.

Management believes that its existing cash and cash equivalents at December 31, 2021 will fund our current operating plan into February 2023. Should our potential mitigating plans which include additional funding through public equity, private equity, debt financing, collaboration partnerships, or other sources, not materialize, then Management would delay certain research projects and capital expenditures and eliminate certain future operating expenses to fund operations at reduced levels in order for the Company to continue as a going concern for a period of 12 months from the date the financial statements are issued.

Smaller Reporting Company Status

We are a “smaller reporting company” as defined in the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We may take advantage of certain of the scaled disclosures available to smaller reporting companies and an exemption from the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002 (“SOX”) regarding our internal control or financial reporting, and will be able to take advantage of these scaled disclosures and exemptions for so long as (i) our voting and non-voting common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter.

Previously, we were an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), until December 31, 2021.

112


 

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risk related to changes in interest rates. Our cash and cash equivalents of $78.5 million as of December 31, 2021 consisted of cash and cash equivalents. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. However, because a significant amount of the marketable securities in our investment portfolio are short-term in nature, an immediate 10% change in market interest rates would not be expected to have a material impact on the fair market value of our investment portfolio or on our financial condition or results of operations.

Item 8. Financial Statements and Supplementary Data.

The financial statements required by this item are set forth beginning on page F-1 of this Annual Report on Form 10-K.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As of December 31, 2021, our management, under the supervision of our Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our management, under the supervision and with the participation of our principal executive officer and principal financial officer, conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2021 based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework). Based on the results of its evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2021.

Remediation of Prior Material Weakness

In our December 31, 2020 Annual Report on Internal Control over Financial Reporting, management determined two material weaknesses existed in our internal control over financial reporting relating to (i) the lack of formal policies and procedures and sufficient complement of personnel to implement effective segregation of duties and (ii) the lack of sufficient formality and evidence of controls over key reports, contracts and spreadsheets.

The control deficiencies created a possibility that a material misstatement to our consolidated financial statements would not be prevented or detected on a timely basis, and therefore we concluded that each of the deficiencies represented a material weakness in our internal control over financial reporting, and that our internal control over financial reporting was not effective as of December 31, 2020.

Throughout the fourth quarter of 2020 and during the year ended December 31, 2021, management conducted remediations to address the material weaknesses noted above. The plan included (i) a robust analysis on our current control environment in order to revamp our existing control processes and procedures, and identify and address any potential gaps, (ii) educating control owners concerning the principles and requirements of each control, (iii) management conducting a more rigorous

113


 

review process for the calculation and reporting over key reports, contracts and spreadsheets, and (iv) the hiring of additional finance and accounting personnel with appropriate expertise to perform specific functions which we believe have resulted in proper segregation of duties, implementation of improved processes and design and operation of key controls.

Through effective implementation of the Company’s remediation plan, the Company has strengthened its internal control environment and has addressed the material weaknesses that were identified at December 31, 2020. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control—Integrated Framework (2013). Based on our assessment, the Company concluded that the material weakness has been remediated as of December 31, 2021.

Attestation Report of the Registered Public Accounting Firm

As a smaller reporting company as defined in the Exchange Act, we are exempt from the auditor attestation requirements of Section 404 of SOX. As a result, our independent registered public accounting firm has not audited or issued an attestation report with respect to the effectiveness of our internal control over financial reporting as of December 31, 2021.

Changes in Internal Control over Financial Reporting

Other than as set forth above, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the year ended December 31, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of F-star Therapeutics, Inc

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of F-star Therapeutics, Inc. and subsidiaries (the Company) as of December 31, 2021, the related consolidated statements of operations and comprehensive loss, stockholders’ equity (deficit) and cash flows, for the year then ended, and the related notes (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

Substantial Doubt about the Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 3 to the consolidated financial statements, the Company has recorded recurring operating losses and will be required to raise additional capital to fund operations. This raises substantial doubt about the Company's ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

F-1


 

Clinical Trial Costs Accruals

The Company's clinical trial costs accrual totaled $2.8 million at December 31, 2021. As discussed in Note 2 and Note 8 to the consolidated financial statements, the Company records accruals for estimated costs incurred related to ongoing clinical trials. When analyzing the adequacy of the accruals, the Company analyzes progress of the studies or trials, including the phase of completion of events, invoices received and contracted costs. This information is obtained from third parties and its research and development personnel. Payments for these activities are based on the terms of the individual arrangements, which may differ from the timing of costs incurred.

Auditing the Company's clinical trial cost accruals was complex and judgmental, as the amounts are based on estimates of the services received related to preclinical studies and clinical trials. The estimates are based on information from a multitude of sources including contract research organizations, investigative sites, company personnel and other vendors. Also, the determination of the nature and level of services that have been received during the period requires judgment because the timing and pattern of vendor invoicing may not correspond to timing of the services provided.

Our audit procedures related to the determination of clinical trial accruals included the following, among others:

We tested the accuracy and completeness of the underlying data used in the estimates and evaluated the reasonableness of assumptions used by management.
We inspected information received by the Company from third parties, which included third parties’ estimate of costs incurred to date and corroborated the progress of clinical trial activities through discussion with the Company’s research and development personnel responsible for the projects.
We inspected the Company's contracts with third parties to assess the impact on amounts recorded.
We performed analytical procedures over fluctuations in accruals by study or trial throughout the period subject to audit and inspected subsequent invoices received from third parties to assess the impact to the accrual.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of F-star Therapeutics, Inc

Opinion on the Financial Statements

We have audited the consolidated balance sheet, consolidated statements of operations and comprehensive loss, of stockholders’ equity (deficit) and of cash flows of F-star Therapeutics, Inc and its subsidiaries (the “Company”) for the year ended December 31, 2020, including the related notes for the year ended December 31, 2020 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and the results of operations and cash flows of the Company for the year ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America.

Substantial Doubt about the Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 3 to the consolidated financial statements, the Company has incurred significant losses and has an accumulated deficit that raises substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 3. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

F-star Therapeutics Inc.

Notes to the Consolidated Financial Statements

1. Nature of the business

F-star Therapeutics Inc. is a clinical-stage biopharmaceutical company dedicated to developing next generation immunotherapies to transform the lives of patients with cancer. We are pioneering the use of tetravalent (2+2) bispecific antibodies to create a paradigm shift in cancer therapy. We have four second generation immuno-oncology (also referred to as "IO") therapeutics in the clinic, each directed against some of the most promising IO targets in drug development, including LAG-3 and CD137. Our proprietary antibody discovery platform is protected by an extensive intellectual property estate. We have attracted multiple partnerships with biotechnology and pharmaceutical companies targeting significant unmet needs across several disease areas, including oncology, immunology, and indications affecting the central nervous system (“CNS”) with over 20 programs, based on our technology, developed by our partners. Our goal is to offer patients better and more durable benefits than currently available immuno-oncology treatments by developing medicines that seek to block tumor immune evasion. Through our proprietary tetravalent, bispecific natural antibody (mAb²™) format, our mission is to generate highly differentiated medicines with monoclonal antibody-like manufacturability, good safety and tolerability.

Share Exchange Agreement

On November 20, 2020, F-star Therapeutics, Inc. (the “Company or F-star”), formerly known as Spring Bank Pharmaceuticals, Inc.(“Spring Bank”), completed its business combination (the “Transaction”) with F-star Therapeutics Limited (“F-star Ltd”) in accordance with the terms of the Share Exchange Agreement, dated July 29, 2020 (the “Exchange Agreement”), by and among the Company, F-star Ltd and the holders of issued shares in the capital stock of F-star Ltd and the holders of convertible notes of F-star Ltd each as set forth therein (each a “Seller”, and collectively with holders of F-star Ltd securities who subsequently became parties to the Exchange Agreement, the “Sellers”). Pursuant to the Exchange Agreement, each ordinary share of F-star Ltd outstanding immediately prior to the closing of the Transaction (the “Closing”) was exchanged by the Seller that owns such F-star Ltd shares for such number of duly authorized, validly issued, fully paid and non-assessable shares of Company common stock as is equal to the exchange ratio formula determined pursuant to the Exchange Agreement (the “Exchange Ratio”), rounded to the nearest whole share of Company common stock (after aggregating all fractional shares of Company common stock issuable to such Seller). Also, on November 20, 2020, in connection with, and prior to completion of, the Transaction, Spring Bank effected a 1-for-4 reverse stock split of its common stock (the “Reverse Stock Split”) and, following the completion of the Transaction, changed its name to “F-star Therapeutics, Inc.” Following the completion of the Transaction, the business of F-star Ltd became the business conducted by Company, which is a clinical-stage immuno-oncology company focused on cancer treatment through its proprietary tetravalent bispecific antibody programs. Unless otherwise noted, all references to share amounts in this report reflect the reverse stock split.

Under the terms of the Exchange Agreement, at the Closing, Spring Bank issued an aggregate of 4,620,618 shares of its common stock to F-star Ltd stockholders, based on an exchange ratio of 0.1125 shares of the Company’s common stock for each F-star Ltd ordinary share, stock option and RSU outstanding immediately prior to the Closing. The exchange ratio was determined through arms-length negotiations between Spring Bank and F-star Ltd pursuant to a formula set forth in the Exchange Agreement.

Pursuant to the Exchange Agreement, immediately prior to the Closing, certain investors in F-star Ltd purchased $15.0 million of F-star Ltd ordinary shares (the “Pre-Closing Financing”). These ordinary shares of F-star Ltd were then exchanged at the Closing for shares of the Company’s common stock in the Transaction at the same exchange rate.

Pursuant to the Exchange Agreement, all outstanding options to purchase Spring Bank common stock were accelerated immediately prior to the Closing and each outstanding option with an exercise price greater than the closing price of the stock on the Closing Date was exercised in full and all other outstanding options to purchase Company common stock were cancelled effective as of the Closing Date.

Immediately following the Reverse Stock Split and the Closing, there were approximately 4,449,559 shares of Spring Bank common stock outstanding. Following the Closing, the F-star Ltd stockholders beneficially owned approximately 53.7% of the combined Company’s common stock and the existing stockholders of Spring Bank beneficially owned approximately 46.3% of the Company’s common stock outstanding. Concurrently with the execution of the Exchange Agreement, certain

F-8


 

officers and directors of Spring Bank and F-star Ltd and certain stockholders of F-star Ltd entered into lock-up agreements (the “Lock-up Agreements”), pursuant to which they agreed to certain restrictions on transfers of any shares of the Company’s common stock for the 180-day period following the Closing, other than the shares of the Company’s common stock received in exchange for ordinary shares of F-star Ltd subscribed for in the Pre-Closing Financing and pursuant to certain other limited exceptions.

In addition, at the Closing, Spring Bank, F-star Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, entered into a STING Agonist Contingent Value Rights Agreement (the “STING Agonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Agonist CVR Agreement, each pre-Reverse Stock Split share of Company common stock held by stockholders as of the record date on November 19, 2020 immediately prior to the Closing received a dividend of one contingent value right (“STING Agonist CVR”), payable on a pre-Reverse Stock Split basis, entitling such holders to receive, in connection with certain transactions involving proprietary STimulator of INterferon Genes (STING) agonist compound designated as SB 11285 occurring on or prior to the STING Agonist CVR Expiration Date (as defined below) that result in aggregate Net Proceeds (as defined in the STING Agonist CVR Agreement) at least equal to the Target Payment Amount (as defined below): an aggregate amount equal to the greater of (i) 25% of the Net Proceeds received from all CVR Transactions (as defined in the STING Agonist CVR Agreement) and (ii) an aggregate amount equal to the product of $1.00 and the total number of shares of Company common stock outstanding as of such record date (not to exceed an aggregate amount of $18.0 million) (the “Target Payment Amount”).

The CVR payment obligation expires on the later of 18 months following the Closing or the one-year anniversary of the date of the final database lock of the Company’s current STING clinical trial (as defined in the STING Agonist CVR Agreement) (the “STING Agonist CVR Expiration Date”). The STING Agonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest and are not registered with the Securities and Exchange Commission (the “SEC”) or listed for trading on any exchange. Until the STING Agonist CVR Expiration Date, subject to certain exceptions, the Company is required to use commercially reasonable efforts to (a) complete the STING Trial and (b) pursue a CVR Transaction. Unless terminated earlier in accordance with its terms, the STING Agonist CVR Agreement became effective upon the Closing will continue in effect until the STING Agonist CVR Expiration Date the payment of all CVR payment amounts are paid pursuant to its terms.

At the Closing, Spring Bank, F-star Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, also entered into a STING Antagonist Contingent Value Rights Agreement (the “STING Antagonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Antagonist CVR Agreement, each share of common stock held by stockholders as of a record date immediately prior to the Closing will receive a dividend of one contingent value right (“STING Antagonist CVR”) entitling such holders to receive, in connection with the execution of a potential development agreement (the “Approved Development Agreement”) and certain other transactions involving proprietary STING antagonist compound occurring on or prior to the STING Antagonist CVR Expiration Date (as defined below) equal to: 80% of all net proceeds (as defined in the STING Antagonist CVR Agreement) received by the Company after the Closing pursuant to (i) the Approved Development Agreement, if any, and (ii) all CVR Transactions (as defined in the STING Antagonist CVR Agreement) entered into prior to the STING Antagonist CVR Expiration Date (as defined below).

The CVR payment obligations expire on the seventh anniversary of the Closing (the “STING Antagonist CVR Expiration Date”). The STING Antagonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest and are not registered with the SEC or listed for trading on any exchange. Until the STING Antagonist CVR Expiration Date, subject to certain exceptions, the Company is required to use commercially reasonable efforts to (a) consummate the Approved Development Agreement to the extent not entered into prior to Closing, (b) to perform the terms of the Approved Development Agreement and (c) pursue CVR Transactions. Unless terminated earlier in accordance with its terms, the STING Antagonist CVR Agreement became effective upon the Closing and will continue in effect until the STING Antagonist CVR Expiration Date or all CVR payment amounts are paid pursuant to its terms.

At the Closing, all issued share options and restricted stock units granted by F-star Ltd under the F-star Therapeutics Limited 2019 Equity Incentive Plan were replaced by options (“Replacement Options”) and awards (“Replacement RSUs”), on the same terms (including vesting), for Company common stock, based on the Exchange Ratio.

The Company’s common stock, which was listed on the Nasdaq Capital Market, traded through the close of business on Friday, November 20, 2020 under the ticker symbol “SBPH” and continued trading on the Nasdaq Capital Market, on a post-Reverse Stock Split adjusted basis, under the ticker symbol “FSTX” beginning on Monday, November 23, 2020. Commencing on November 23, 2020, the Company’s common stock was represented by a new CUSIP number, 30315R 107. The combined company is now headquartered out of F-star Ltd existing facilities in Cambridge, U.K. and office in Cambridge, MA.

The Transaction was accounted for as a business combination using the acquisition method of accounting under the provisions of Financial Accounting Standards Board, Accounting Standards Codification (“ASC 805”), Topic 805 “Business Combinations” (“ASC 805”). The Transaction was accounted for as a reverse acquisition with F-star Ltd being deemed the acquiring company for accounting purposes. Under ASC 805, F-star Ltd as the accounting acquirer, recorded the assets acquired and liabilities assumed of Spring Bank Pharmaceuticals, Inc in the Transaction at their fair values as of the acquisition date (Note 4).

F-star Ltd was determined to be the accounting acquirer based on an analysis of the criteria outlined in ASC 805 and the facts and circumstances specific to the Transaction, including the fact that immediately following the Transaction: (1) F-star Ltd shareholders owned the majority of the voting rights of the combined company; (2) F-star Ltd designated a majority (five of eight) of the initial members of the board of directors of the combined company; and (3) F-star Ltd senior management held the key positions in senior management of the combined company. As a result, upon consummation of the Transaction, the historical financial statements of F-star Ltd became the historical financial statements of the combined organization.

Risks and Uncertainties

The Company is subject to risks common to companies in the biotechnology industry, including but not limited to, risks of failure of preclinical studies and clinical trials, the need to obtain marketing approval for any drug product candidate that it may identify and develop, the need to successfully commercialize and gain market acceptance of its product candidates, dependence on key personnel and collaboration partners, protection of proprietary technology, compliance with government regulations, development by competitors of technological innovations, and the ability to secure additional capital to fund operations. Product candidates currently under development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval prior to commercialization. Even if the Company’s research and development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

Impact of COVID-19 on our Business

The continued spread of the COVID-19 pandemic has been evolving, and to date has led to the implementation of various responses, including government-imposed quarantines, travel restrictions and other public health safety measures.

Management continues to closely monitor the impact of the COVID-19 pandemic on all aspects of the business, including how it will impact operations and the operations of customers, vendors, and business partners. The extent to which COVID-19 impacts the future business, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence at this time, such as new information that may emerge concerning the emergence or severity of other strains of COVID-19 or the effectiveness of actions to vaccinate against or contain COVID-19 or treat its impact, among others. If we or any of the third parties with which we engage, however, were to experience shutdowns or other business disruptions, the ability to conduct business in the manner and on the timelines presently planned could be materially and negatively affected, which could have a material adverse impact on business, results of operations and financial condition. The estimates of the impact on our business may change based on new information that may emerge concerning COVID-19 and the actions to contain it or treat its impact and the economic impact on local, regional, national, and international markets.

Management have not identified any triggering events which would result in any significant impairment losses in the carrying values of assets as a result of the pandemic and are not aware of any specific related event or circumstance that would require management to revise estimates reflected in these consolidated financial statements.

2. Summary of Significant Accounting Policies

Basis of Presentation

The Company’s financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”).

The accompanying consolidated financial statements include the accounts of F-star Therapeutics Inc. and its wholly owned subsidiaries: F-star Therapeutics Limited, (F-star Ltd) and F-star Therapeutics Securities Corporation.

All intercompany balances and transactions between the consolidated companies have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting years. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the fair value of the assets and liabilities acquired in the Transaction between Spring Bank and F-star Ltd, fair value of the convertible loan, the accrual for research and development expenses, revenue recognition, fair values of acquired intangible assets and impairment review of those assets, share based compensation expense, and income taxes. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed in light of reasonable changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates or assumptions.

Foreign currency and currency translation

The functional currency is the currency of the primary economic environment in which an entity’s operations are conducted. The Company and its subsidiaries operate mainly in the United Kingdom and United States. The Company’s reporting currency is the U.S dollar. The Company translates the assets and liabilities of its subsidiaries into U.S. dollar at the exchange rate in effect on the balance sheet date.

Revenues and expenses are translated at the average exchange rate in effect during each monthly period. Unrealized translation gains and losses are recorded as a cumulative translation adjustment, which is included in the consolidated statements of shareholders’ equity as a component of accumulated other comprehensive loss. Translation differences resulting from the conversion from functional currency to reporting currency are included as part of the cumulative foreign currency translation adjustment, which is reported as a component of shareholders’ equity under accumulated other comprehensive loss.

Monetary assets and liabilities denominated in currencies other than the functional currency are remeasured into the functional currency at rates of exchange prevailing at the balance sheet dates. Non-monetary assets and liabilities denominated in foreign currencies are remeasured into the functional currency at the exchange rates prevailing at the date of the Transaction. Exchange gains or losses arising from foreign currency transactions are included in the determination of net loss for the respective periods.

Adjustments that arise from exchange rate changes on transactions denominated in a currency other than the local currency are included in other (expense) income in the consolidated statements of operations and comprehensive loss as incurred. The Company recorded a foreign exchange loss of $0.4 million and a gain of $0.6 million included in other (expense) income in the consolidated statement of operations and comprehensive loss for the years ended December 31, 2021, and 2020, respectively.

Concentrations of credit risk and of significant suppliers

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains its cash and cash equivalents in financial institutions in amounts that could exceed government-insured limits. The Company does not believe it is subject to additional credit risks beyond those normally associated with commercial banking relationships.

The Company is dependent on third-party manufacturers to supply products for research and development activities in its programs. In particular, the Company relies and expects to continue to rely on a small number of manufacturers to supply its requirements for supplies and raw materials related to these programs. These programs could be adversely affected by a significant interruption in these manufacturing services or the availability of raw materials.

Cash and cash equivalents

The Company considers all highly liquid investments with original maturities of three months or less at date of purchase to be cash equivalents. The Company had no cash equivalents on December 31, 2021, and 2020.

Property, plant and equipment

Property, plant and equipment are stated at cost, less accumulated depreciation . Depreciation expense is recognized using the straight-line method over the estimated useful lives of the respective assets as follows:

 

 

 

Estimated Useful Economic Life

Leasehold property improvements, right of use assets

 

Lesser of lease term or useful life

Laboratory equipment

 

5 years

Furniture and office equipment

 

3 years

 

Costs for capital assets not yet placed into service are capitalized as construction-in-progress and depreciated in accordance with the above guidelines once placed into service. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in loss from operations. As of December 31, 2021, and 2020, there have been no significant asset retirements to date. Expenditures for repairs and maintenance that do not improve or extend the lives of the respective assets are charged to expense as incurred.

Impairment of long-lived assets

Long-lived assets consist of property, plant and equipment, goodwill, and intangible assets. Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets. An impairment loss would be recognized as a loss from operations when estimated undiscounted future cash flows expected to result from the use of an asset group or the estimated return on investment are less than its carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value, determined based on discounted cash flow or return on investment calculations.

Business Combinations and Goodwill

Business combinations are accounted for in accordance with ASC Topic 805 “Business Combinations”. The total purchase price of an acquisition is allocated to the underlying identifiable net assets, based on their respective estimated fair values as of the acquisition date. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, probabilities of success, discount rates, and asset lives, among other items. Assets acquired and liabilities assumed are recorded at their estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Goodwill is tested for impairment at the reporting unit level annually in the fourth quarter, or more frequently when events or changes in circumstances indicate that the asset might be impaired. Examples of such events or circumstances include, but are not limited to, a significant adverse change in legal or business climate, an

F-12


 

adverse regulatory action or unanticipated competition. The Company has determined that it operates in a single operating segment and has a single reporting unit. To perform its quantitative test, the Company compares the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value of its net assets, goodwill is not impaired, and no further testing is required. If the fair value of the reporting unit is less than the carrying value, the Company measures the amount of impairment loss, if any, as the excess of the carrying value over the fair value of the reporting unit. Required annual testing of goodwill for impairment was completed as of December 31, 2021 and determined that goodwill is not impaired.

Contingent value rights

The fair value of the contingent value rights is based on the Company’s probability-weighted discounted cash flow assessment that considers probability and timing of future payments in relation to the achievement of a sale or licensing arrangement for the STING product candidates, or the achievement of future development, regulatory and sales-based milestones in existing agreements. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving a sale, licensing agreement or milestone, anticipated timelines, and discount rate. Changes in the fair value of the liability will be recognized in the consolidated statement of operations and comprehensive loss until settlement.

Acquired In-Process Research and Development (IPR&D)

Acquired IPR&D represents the fair value assigned to research and development assets that the Company acquires and have not been completed at the acquisition date. The fair value of IPR&D acquired in a business combination is recorded on the consolidated balance sheets at the acquisition-date fair value and is determined by estimating the costs to develop the technology into commercially viable products, estimating the resulting revenue from the projects, and discounting the projected net cash flows to present value. Indefinite lived IPR&D is not amortized, but rather is reviewed for impairment on an annual basis or more frequently if indicators of impairment are present, until the project is completed, abandoned or transferred to a third party. The projected discounted cash flow models used to estimate the fair value of partnered assets and cost approach model used to estimate proprietary assets as part of the Company’s Indefinite lived IPR&D reflect significant assumptions regarding the estimates a market participant would make in order to evaluate a drug development asset, including the following:

Estimates of obsolescence of development expenditure;
Probability of successfully completing clinical trials and obtaining regulatory approval;
Estimates of future cash flows from potential milestone payments and royalties related to out-licensed product sales; and
A discount rate reflecting the Company’s weighted average cost of capital and specific risk inherent in the underlying assets.

Once brought into use, Indefinite lived IPR&D is reclassified into Long lived IPR&D assets and are amortized over their estimated useful economic lives, which is the lower of the expected royalty term or the remaining life of the relevant patents, whichever is shorter. The Company periodically reviews its Long lived IPR&D assets to determine whether events and circumstances warrant a revision to the remaining period of amortization or asset impairment.

Fair value measurements of financial instruments

The Company’s financial instruments consist of cash, accounts payable, CVR and liability classified warrants. The carrying amounts of cash and accounts payable approximate their fair value due to the short-term nature of those financial instruments. The fair value of CVR and the liability classified warrants are remeasured to fair value each reporting period.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurement (“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs

F-13


 

that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances.

ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy that distinguishes between the following:

Level 1 — Quoted prices in active markets for identical assets or liabilities.
Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.
Level 3 — Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents, and other current assets, research and development incentives receivable, accounts payable and term debt and accrued liabilities and other current liabilities approximate their fair values, due to their short-term nature.

Segment and geographic information

Operating segments are defined as components of a business for which separate discrete financial information is available for evaluation by the chief operating decision maker in deciding how to allocate resources and assess performance. The Company and its chief operating decision maker, the Company’s Chief Executive Officer, view the Company’s operations and manage its business as a single operating segment. The Company operates in two geographic areas: the United Kingdom and United States.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in the Company’s consolidated balance sheets. The Company has not entered any financing leases.

ROU assets represent the Company’s right to use and control an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The ROU asset also includes lease payments made before the lease commencement date and excludes any lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

The components of a lease shall be split into three categories, if applicable: lease components (e.g., land, building, etc.), non-lease components (e.g., common area maintenance, maintenance, consumables, etc.), and non-components (e.g., property taxes, insurance, etc.). The fixed and in-substance fixed contract consideration (including any related to non-components) must then be allocated based on fair values to the lease components and non-lease components. The Company’s facilities operating leases may have lease and non-lease components to which the Company has elected to apply a practical expedient to account for each lease component and related non-lease component as one single component. The lease component results

F-14


 

in a right-of-use asset being recorded on the consolidated balance sheets. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

License and collaboration arrangements and revenue recognition

The Company’s revenues are generated primarily through license and collaboration agreements with pharmaceutical and biotechnology companies. The terms of these arrangements may include (i) the grant of intellectual property rights (IP licenses) to therapeutic drug candidates against specified targets, developed using the Company’s proprietary mAb2 bispecific antibody platform, (ii) performing research and development services to optimize drug candidates, and (iii) the grant of options to obtain additional research and development services or licenses for additional targets, or to optimize product candidates, upon the payment of option fees.

The terms of these arrangements typically include payment to the Company of one or more of the following: non-refundable, upfront license fees; payments for research and development services; fees upon the exercise of options to obtain additional services or licenses; payments based upon the achievement of defined collaboration objectives; future regulatory and sales-based milestone payments; and royalties on net sales of future products.

The Company accounts for contracts with customers in accordance with ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"). The company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized under ASC 606, the Company performs the following steps:

(i)
identify the promised goods or services in the contract;
(ii)
determine whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract;
(iii)
measurement of the transaction price, including the constraint on variable consideration;
(iv)
allocation of the transaction price to the performance obligations; and
(v)
recognition of revenue when (or as) the Company satisfies each performance obligation.

As part of the accounting for these arrangements, the Company must make significant judgments, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each performance obligation.

Once a contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within the contract and determines those that are performance obligations. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. The Company assesses if these options provide a material right to the customer and if so, they are considered performance obligations.

Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the customer. The promised goods or services in the Company’s contracts with customers primarily consist of license rights to the Company’s intellectual property for research and development, research and development services, options to acquire additional research and development services, and options to obtain additional licenses, such as a commercialization license for a potential product candidate. Promised goods or services are considered distinct when:

(i)
the customer can benefit from the good or service on its own or together with other readily available resources; and
(ii)
the promised good or service is separately identifiable from other promises in the contract.

In assessing whether promised goods or services are distinct, the Company considers factors such as the stage of development of the underlying intellectual property, the capabilities of the customer to develop the intellectual property on their own and whether the required expertise is readily available. In addition, the Company considers whether the collaboration partner can benefit from a promise for its intended purpose without the receipt of the remaining promises, whether the value of the promise is dependent on the unsatisfied promises, whether there are other vendors that could provide the remaining promises, and whether it is separately identifiable from the remaining promises. The Company estimates the

F-15


 

transaction price based on the amount of consideration the Company expects to receive for transferring the promised goods or services in the contract. The consideration may include both fixed consideration and variable consideration. At the inception of each arrangement that includes variable consideration, the Company evaluates the amount of the potential payments and the likelihood that the payments will be received. The Company utilizes either the most likely amount method or expected value method to estimate variable consideration to include in the transaction price based on which method better predicts the amount of consideration expected to be received. The amount included in the transaction price is constrained to the amount for which it is probable that a significant reversal of cumulative revenue recognized will not occur. At the end of each subsequent reporting period, the Company re-evaluates the estimated variable consideration included in the transaction price and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis in the period of adjustment.

After the transaction price is determined it is allocated to the identified performance obligations based on the estimated standalone selling price. The Company must develop assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. The Company utilizes key assumptions to determine the standalone selling price, which may include other comparable transactions, pricing considered in negotiating the transaction, probabilities of technical and regulatory success and the estimated costs. Certain variable consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated to each performance obligation are consistent with the amounts the Company would expect to receive for each performance obligation.

The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time based on the use of an input method.

The Company accounts for contract modifications as a separate contract if both of the following conditions are met:

(i)
the scope of the contract increases because of the addition of promised goods or services that are distinct; and
(ii)
the price of the contract increases by an amount of consideration that reflects standalone selling prices of the additional promised goods or services and any appropriate adjustments to that price to reflect the circumstances of the particular contract.

If a contract modification is deemed to not be a separate contract, then the transaction price is updated and allocated to the remaining performance obligations (both from the existing contract and the modification). Previously recognized revenue for goods and services that are not distinct from the modified goods or services is adjusted based upon an updated measure of progress for the partially satisfied performance obligations.

If a contract modification is deemed to be a separate contract, any revenue recognized under the original contract is not retrospectively adjusted and any performance obligations remaining under the original contract continue to be recognized under the terms of that contract.

The Company’s collaboration revenue arrangements include the following:

Up-front License Fees: If a license is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from nonrefundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone payments: The Company’s collaboration agreements may include development and regulatory milestones. The Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. The Company evaluates factors such as the scientific, clinical, regulatory, commercial, and other risks that must be overcome to achieve the particular milestone in making this assessment.

F-16


 

If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. At the end of each reporting period, the Company re-evaluates the probability of achievement of such milestones and any related constraint, and if necessary, adjusts the estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect collaboration revenue and net loss in the period of adjustment.

Customer Options: The Company evaluates the customer options to obtain additional items (i.e., additional license rights) for material rights, or options to acquire additional goods or services for free or at a discount. Optional future services that reflect their standalone selling prices do not provide the customer with a material right and, therefore, are not considered performance obligations and are accounted for as separate contracts. If optional future services include a material right, they are accounted for as performance obligations. The Company determines an estimated standalone selling price of any material rights for the purpose of allocating the transaction price. The Company considers factors such as the identified discount and the probability that the customer will exercise the option. Amounts allocated to a material right are not recognized as revenue until, at the earliest, the option is exercised or expires.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on a level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any revenue related to sales-based royalties or milestone payments based on the level of sales.

Research and Development Services: The promises under the Company’s collaboration agreements may include research and development services to be performed by the Company on behalf of the partner. Payments or reimbursements resulting from the Company’s research and development efforts are recognized as the services are performed and presented on a gross basis because the Company is the principal for such efforts.

Research and development costs

Research and development costs are expensed as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries, share-based compensation and benefits, facilities costs and laboratory supplies, depreciation, amortization and impairment expense, manufacturing expenses and external costs of outside vendors engaged to conduct preclinical development activities and clinical trials as well as the cost of licensing technology. Typically, upfront payments and milestone payments made for the licensing of technology are expensed as research and development in the period in which they are incurred, except for payments relating for intellectual property rights with future alternative use which will be expensed when the intellectual property is in use. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed.

F-17


 

Research and manufacturing contract costs and accruals

The Company has entered into various research and development contracts with companies both inside and outside of the United States. These agreements are generally cancelable, and related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies or trials, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical accrual estimates have not been materially different from the actual costs.

Research and development incentives and receivable

The Company, through its subsidiary in the United Kingdom, receives reimbursements of certain research and development expenditures as part of a United Kingdom government’s research and development tax reliefs program. Under the program, the Company is able to surrender trading losses that arise from qualifying research and development expenses incurred in the United Kingdom for a tax credit of up to 14.5% of the surrender able losses. Management has assessed the Company’s research and development activities and expenditures to determine which activities and expenditures are likely to be eligible under the research and development incentive program described above. At each period end, management estimates the reimbursement available to the Company based on available information at the time.

The Company recognizes income from the research and development incentives when the relevant expenditure has been incurred, the associated conditions have been satisfied and there is reasonable assurance that the reimbursement will be received. The Company records these research and development incentives as a reduction to research and development expenses in the consolidated statements of operations and comprehensive loss, as the research and development tax credits are not dependent on the Company generating future taxable income, the Company’s ongoing tax status, or tax position. The research and development incentives receivable represent an amount due in connection with the above program. The Company recorded a reduction to research and development expense of $2.2 million and $3.3 million for the years ended December 31, 2021 and 2020, respectively.

Patent costs

All patent-related costs incurred in connection with preparing, filing and prosecuting patent applications are expensed as incurred due to the uncertainty about the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses in the consolidated statements of operations and comprehensive loss.

Warrants

The Company accounts for freestanding warrants within stockholder’s equity or as liabilities based on the characteristics and provisions of each instrument. The Company evaluates outstanding warrants in accordance with Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity, and ASC 815, Derivatives and Hedging. If none of the criteria in the evaluation in these standards are met, the warrants are classified as a component of stockholders’ equity and initially recorded at their grant date fair value without subsequent remeasurement. Warrants that meet the criteria are classified as liabilities and remeasured to their fair value at the end of each reporting period.

Share-based compensation

The Company accounts for share-based compensation in accordance with ASC 718, "Compensation – Stock Compensation”(“ASC 718”). ASC 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service period in the Company’s consolidated statements of operations and comprehensive loss.

The Company records the expense for option awards using a graded vesting method. The Company accounts for forfeitures as they occur. For share-based awards granted to non-employee consultants, the measurement date for non-employee awards is the date of grant. The compensation expense is then recognized over the requisite service period, which is the vesting period of the respective award.

F-18


 

The Company reviews stock award modifications when there is an exchange of original award for a new award. The Company calculates for the incremental fair value based on the difference between the fair value of the modified award and the fair value of the original award immediately before it was modified. The Company immediately recognizes the incremental value as compensation cost for vested awards and recognizes, on a prospective basis over the remaining requisite service period, the sum of the incremental compensation cost and any remaining unrecognized compensation cost for the original award on the modification date.

The fair value of stock options (“options”) on the grant date is estimated using the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including the option’s expected term and the price volatility of the underlying stock, to determine the fair value of the award.

Prior to November 20, 2020, given the absence of an active market for the ordinary shares of F-star Ltd, the board of directors determined the estimated fair value of the Company’s equity instruments based on input from management, which utilized the most recently available independent third-party valuation, and considering a number of objective and subjective factors, including external market conditions affecting the biotechnology industry sector. Each valuation methodology includes estimates and assumptions that require judgment. These estimates and assumptions include a number of objective and subjective factors in determining the value of F-star Ltd ordinary shares at each grant date. The expected volatility for F star Ltd was calculated based on reported volatility data for a representative group of publicly traded companies for which historical information was available. The historical volatility is calculated based on a period of time commensurate with the assumption used for the expected term. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption. F-star Ltd used the simplified method, under which the expected term is presumed to be the midpoint between the vesting date and the end of the contractual term. F-star Ltd utilized this method due to the lack of historical exercise data and the plain nature of its share-based awards.

The Company uses the remaining contractual term for the expected life of non-employee awards. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends.

The Company classifies share-based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

Comprehensive loss

Comprehensive loss includes net loss as well as other changes in shareholders’ equity (deficit) that result from transactions and economic events other than those with shareholders. The Company records unrealized gains and losses related to foreign currency translation as a component of other comprehensive loss in the consolidated statements of operations and comprehensive loss.

Contingencies

Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. At each reporting date, the Company evaluates whether or not a potential loss amount or a potential loss range is probable and reasonably estimable under the provisions of the authoritative guidelines that address accounting for contingencies. The Company expenses costs as incurred in relation to such legal proceedings as general and administrative expense within the consolidated statements of operations and comprehensive loss.

Income taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded

F-19


 

in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies.

The Company accounts for uncertainty the consolidated financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the consolidated financial statements. The amount of the benefit that may be recognized is the largest amount that will more likely than not be realized upon ultimate settlement. Any provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties.

Research and development tax credits received in the U.K. are recorded as a reduction to research and development expenses. The U.K. research and development tax credit is payable to the Company after surrendering tax losses and is not dependent on current or future taxable income. As a result, it is not reflected as part of the income tax provision. If, in the future, any U.K. research and development tax credits generated are utilized to offset a corporate income tax liability in the U.K., that portion would be recorded as a benefit within the income tax provision and any refundable portion not dependent on taxable income would continue to be recorded as a reduction to research and development expenses.

Net loss per share

The Company computes net loss per share in accordance with ASC Topic 260,"Earnings Per Share”(“ASC 260”) and related guidance, which requires two calculations of net loss attributable to the Company’s shareholders per share to be disclosed: basic and diluted. Convertible preferred shares are participating securities and are included in the calculation of basic and diluted net loss per share using the two-class method. In periods where the Company reports net losses, such losses are not allocated to the convertible preferred shares for the computation of basic or diluted net loss.

Diluted net loss per share is the same as basic net loss per share for the periods in which the Company had a net loss because the inclusion of outstanding common stock equivalents would be anti-dilutive.

Reclassifications

Certain items in the prior year’s consolidated financial statements have been reclassified to conform to the current presentation.

Recently issued and adopted accounting pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that the Company adopts as of the specified effective date. Unless otherwise discussed below, the Company does not believe that the adoption of recently issued standards have or may have a material impact on its consolidated financial statements and disclosures.

Government assistance

In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832) – Disclosures by Business Entities about Government Assistance to add annual disclosure requirements related to transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. The standard is effective for annual periods beginning after December 15, 2021, with early adoption permitted. The Company adopted the new standard on January 1, 2022 and does not expect the adoption of this standard to have a significant impact on the disclosures of its consolidated financial statements.

3. Going Concern

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates realization of assets and the satisfaction of liabilities and commitments in the normal course of business. Since inception, the Company has devoted substantially all of its efforts to business planning, research and development, pre-clinical and clinical activities, recruiting management and technical staff, and securing funding via collaborations. The Company has historically funded its operations with proceeds from its collaboration arrangements, sale of equity capital, proceeds from sales of convertible notes and debt financing. As of December 31, 2021, the Company has incurred significant losses and has an accumulated deficit of $78.5 million. The Company had approximately $78.5 million in cash and cash equivalents as of December 31, 2021. The Company expects to continue to generate operating losses in the foreseeable future, particularly as the Company advances its pre-clinical activities and clinical trials for its product candidates in development. The Company plans to seek additional funding through public equity, private equity, debt financing, collaboration partnerships, or other sources. There are no assurances, however, that the Company will be successful in these endeavors.

If the Company is unable to obtain funding, the Company could be forced to delay, reduce, or eliminate its research and development programs, or reduce product candidate expansion, which could adversely affect its business prospects. Although management continues to pursue its funding plans, there is no assurance that the Company will be successful in obtaining sufficient funding to continue operations on terms acceptable to the Company, if at all. Management believes that its existing cash and cash equivalents at December 31, 2021 will fund our current operating plan into February 2023. Accordingly, the Company has concluded that substantial doubt exists about the Company’s ability to continue as a going concern for a period of at least twelve months from the date of the financial statements.

4. Business Combination

As described in Note 1 above, on November 20, 2020, F-star Ltd completed its business combination with Spring Bank. For accounting purposes, the purchase price was based on (i) the fair value of Spring Bank common stock as of the Transaction date of $21.5 million which was determined based on the number of shares of common stock in connection with the Transaction, (ii) the portion of the fair value attributable to in the money fully and partially vested stock options and warrants.

Under the acquisition method of accounting, the total purchase price is allocated to the acquired tangible and intangible assets and assumed liabilities based on their fair values as of the acquisition date. Any excess purchase price over the fair value of assets acquired and liabilities assumed is allocated to goodwill. Acquired in-process research and development assets will be classified as indefinite-lived intangible assets and will be amortized over their estimated useful economic lives when put into use. The fair values of acquired in-process research and development assets were calculated using an income approach based on the expected future cash flows associated with the respective asset using an estimated discount rate of 14%.

We are one segment and one reporting unit. The goodwill was primarily attributable to the access F-star Ltd gained to the Nasdaq public listing. The Company determined that the underlying goodwill and intangible assets are not deductible for tax purposes.

For the year ended December 31, 2020, the Company incurred acquisition-related expenses of approximately $4.2 million which are included in general and administrative expenses.

A liability was recognized for the contingent value rights assumed by the Transaction. The fair value estimate for the contingent value rights was estimated at $2.5 million and is based on the probability weighted achieved over the estimated period. Any change in the fair value of the contingent value rights to the acquisition date, including changes from events after the acquisition date, such as changes in our estimate will be recognized in earnings in the period the estimated fair value changes. A change in fair value of the contingent value rights could have a material effect on the statement of operations and financial position in the period of the change in estimate.

The results of this acquisition were included in the Company’s consolidated statement of operations and comprehensive loss beginning on November 20, 2020.

The Company’s consolidated net loss for the year ended December 31, 2020, included a loss of $1.7 million for Spring Bank operations since the Transaction date.

The Company classified the contingent value rights within Level 3 because their fair values are determined using net present value techniques, based upon non-public information estimated by management. The fair value of the contingent value rights is based on the Company’s probability-weighted discounted cash flow assessment that considers probability and timing of future payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving a sale or licensing agreement, anticipated timelines, and discount rate. The Company classified the Warrants as Level 3 because the fair values are based upon non-public information estimated by management. Further disclosure of these estimates are disclosed in Note 10 Warrants.

9. Term Debt

On April 1, 2021, the Company, as borrower, entered into the Loan and Security Agreement with Horizon, as lender and collateral agent for itself. The Loan and Security Agreement provides for four separate and independent $2.5 million term loans (Loan A, Loan B, Loan C, and Loan D), whereby, upon the satisfaction of all the conditions to the funding of the Term Loans, each Term Loan will be delivered by Horizon to the Company in the following manner: (i) Loan A was delivered by Horizon to the Company by April 1, 2021, (ii) Loan B was delivered by Horizon to the Company by April 1, 2021, (iii) Loan C was delivered by Horizon to the Company by June 30, 2021, and (iv) Loan D was delivered by Horizon to the Company by June 30, 2021. The Company may only use the proceeds of the Term Loans for working capital or general corporate purposes as contemplated by the Loan and Security Agreement. On April 1, 2021, the Company drew down $5 million. On June 22, 2021, the Company drew down another $5 million under this facility. The Company incurred $0.2 million of debt issuance costs and issued $0.3 million of warrants.

The term note matures on the 48-month anniversary following the funding date, therefore $5 million plus an additional fee of $0.2 million becomes due on April 1, 2025, and $5 million plus an additional fee of $0.2 million will become due on June 22, 2025. The principal balance the Term Loan bears a floating interest. The interest rate is calculated initially and, thereafter, each calendar month as the sum of (a) the per annum rate of interest from time to time published in The Wall Street Journal as contemplated by the Loan and Security Agreement, or any successor publication thereto, as the “prime rate” then in effect, plus (b) 6.25%; provided that, in the event such rate of interest is less than 3.25%, such rate shall be deemed to be 3.25% for purposes of calculating the interest rate. Interest is payable on a monthly basis based on each Term Loan principal amount outstanding the preceding month and at December 31, 2021 the effective rate applied was 13.4%.

The Company may, at its option upon at least five business days’ written notice to Horizon, prepay all or any portion of the outstanding Term Loan by simultaneously paying to Horizon an amount equal to (i) any accrued and unpaid interest on the outstanding principal balance of the Term Loan so prepaid; plus (ii) an amount equal to (A) if such Term Loan is prepaid on or before the Loan Amortization Date (as defined in the Loan and Security Agreement) applicable to such Term Loan, three percent of the then outstanding principal balance of such Term Loan, (B) if such Term Loan is prepaid after the Loan Amortization Date applicable to such Term Loan, but on or before the date that is 12 months after such Loan Amortization Date, two percent of the then outstanding principal balance of such Term Loan, or (C) if such Term Loan is prepaid more than 12) months after the Loan Amortization Date applicable to such Term Loan, one percent of the then outstanding principal balance of such Term Loan; plus (iii) the outstanding principal balance of such Term Loan; plus (iv) all other sums, if any, that had become due and payable under the Loan and Security Agreement.

During 2019, Spring Bank entered into an agreement with Pontifax Medison Finance (Israel) L.P. and Pontifax Medison Finance (Cayman) L.P., as lenders, and Pontifax Medison Finance GP, L.P warrants to purchase 62,500 shares of common stock (the “Pontifax Warrants”). The Pontifax Warrants are exercisable at $8.32 per share and expire on September 19, 2025. The Company evaluated the terms of the warrants and concluded that they should be equity-classified. At December 31, 2021, there were 62,500 warrants outstanding.

 

F-25


 

In connection with the entry into the Loan and Security Agreement (refer to Note 9), the Company has issued to Horizon warrants to purchase an aggregate number of shares of the Company’s common stock in an amount equal to $100,000 divided by the exercise price for each respective warrant. The warrants, which are exercisable for an aggregate of 42,236 shares, will be exercisable for a period of seven years at a per-share exercise price of $9.47, which is equal to the 10-day average closing price prior to January 15, 2021, the date on which the term sheet relating to the Loan and Security Agreement was entered into, subject to certain adjustments as specified in the warrant. At December 31, 2021, there were 42,236 warrants outstanding

Incentive Plans

2019 Equity Incentive plan

On June 14, 2019, the F-star Ltd board of directors and shareholders approved the 2019 Equity Incentive Plan (or the “2019 Plan”). As of December 31, 2020 there were 33,778 shares available for issuance. On January 1, 2021, pursuant to the evergreen provision of the 2019 Plan, the 2019 Plan was increased by 364,005 to 397,783 shares available for issuance under the 2019 plan.

Awards granted under the 2019 Plan generally vest over a four-year service period with 25% or 28% of the award vesting on the first anniversary of the commencement date and the balance vesting monthly over the remaining three years. Awards generally expire 10 years from the date of the grant. For certain senior members of management and directors, the board of directors approved an alternative vesting schedule. As of December 31, 2021, there were 79,242 shares available for issuance under the 2019 Plan.

Amended and Restated 2015 Stock Incentive Plan

In March 2018, the Board approved the Amended and Restated 2015 Plan. Upon receipt of stockholder approval at the Company’s 2018 annual meeting in June 2018, the 2015 Plan was amended and restated in its entirety increasing the authorized number of shares of common stock reserved for issuance by 800,000 shares (together with the 2014 Plan, the 2015 Plan, the “Stock Incentive Plans”). Pursuant to the Amended and Restated 2015 Plan, there are 1,666,863 shares authorized for issuance. In addition, to the extent any outstanding awards under the 2014 Plan expire, terminate or are otherwise surrendered, cancelled or forfeited after the closing of the Company’s IPO, those shares are added to the authorized shares under the Amended and Restated 2015 Plan. The total amount of shares authorized for issuance under both the 2014 Plan and the Amended and Restated 2015 Plan is 2,300,000.

Pursuant to the Exchange Agreement, all outstanding options to purchase Company common stock were accelerated immediately prior to the Closing and each outstanding option with an exercise price less than the trading price of the Company common stock as of the close of trading on the Closing Date was exercised in full and all other outstanding options to purchase Company common stock were cancelled effective as of the Closing Date. As of December 31, 2021, the Company had 101,583 shares available for issuance under the Amended and Restated 2015 Plan.

Stock option valuation

The fair value of stock option grants is estimated using the Black-Scholes option-pricing model with the following assumptions:.

 

 

 

2021

 

 

2020

 

Risk-free interest rate

 

0.42% - 1.34%

 

 

0.17% - 0.42%

 

Expected volatility

 

97.18% - 98.96%

 

 

82.8% - 98.3%

 

Expected dividend yield

 

 

%

 

 

%

Expected life (in years)

 

 

6.1

 

 

 

5.1

 

 

Expected Term—The expected term represents management’s best estimate for the options to be exercised by option holders.

Volatility—Since F-star Ltd did not have a trading history for its common stock, the expected volatility was derived from the historical stock volatilities of comparable peer public companies within its industry that are considered to be comparable to F-star Ltd business over a period equivalent to the expected term of the share-based awards. After the closing of the Transaction, the volatility of the Company’s Common Stock is used to determine volatility of the share-based awards at grant date.

Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the date of grant for zero-coupon U.S. Treasury notes with maturities approximately equal to the share-based awards’ expected term.

Dividend Rate—The expected dividend is zero as the Company has not paid nor does it anticipate paying any dividends on its common stock in the foreseeable future.

Fair Value of Common Stock— Prior to the Transaction on November 20, 2020, F-star Ltd estimated fair value used three different methodologies, the income approach, the market approach and cost approach. The income approach uses the estimated present value of economic benefits. The market approach exams observable market values for similar assets or securities. The cost approach uses the concept of replacement cost as an indicator of value and the notion that an investor would pay no more for an asset that what it would cost to replace the asset with one of equal utility. After the closing of the Transaction, the fair value of the Company’s Common Stock is used to estimate the fair value of the share-based awards at grant date.

2019 License and collaboration agreement with Ares Trading S.A.

Summary

On May 14, 2019, the Company entered into a licensing and collaboration agreement ("2019 LCA") with Ares, pursuant to which the Company granted the option to enter into a worldwide, exclusive license to certain patents and know-how to develop, manufacture and commercialize two separate mAb2 antibody products that each contain a specific Fcab and a Fab target pair (each a licensed product).

For the exclusive rights granted in relation to the first molecule, an option fee of $11.1 million was paid by Ares to the Company. Following receipt of the option fee, Ares became responsible for the development of the molecule and development, regulatory and sales-based royalties become payable to Company upon achievement of specified events.

On July 15, 2020, a deed of amendment (the “2020 Amendment”) was entered into in respect of the 2019 LCA. The 2020 Amendment had two main purposes (i) to grant additional options to acquire intellectual property rights for a third and fourth molecule; and (ii) to allow Ares to exercise its option early to acquire intellectual property rights to the second molecule included in the 2019 LCA as well as to terminate the research and development services. On execution of the amendment, an option fee of $8.5 million was paid by Ares to the Company to acquire rights to the second molecule.

During March 2021 Ares paid an option fee of $2.7 million to acquire the rights to the third molecule.

As a result of the 2020 Amendment, the maximum amount payable by Ares on the achievement of certain development and regulatory milestones in the aggregate was increased to $473.9 million, and the maximum amount payable on the achievement of certain commercial milestones was increased to $292.3 million. In addition, to the extent that any product candidates covered by the exclusive licenses granted to Ares are commercialized, the Company will be entitled to receive a single digit royalty based on a percentage of net sales on a country-by-country basis.

Revenue recognition

Management has considered the performance obligations identified in the Ares LCA and concluded that where research and development services are supplied to the customer in relation to a specific molcule the option for the grant of intellectual property rights is not distinct from the provision of research and development services, as the services would significantly modify the early-stage intellectual property. As a result, the option for the grant of intellectual property rights and the provision of research and development services has been combined into a single performance obligation for the second molcule included in the 2019 LCA. The Company recognized revenue related to this molecule using the cost-to-cost method, which it believes best depicted the transfer of control of the services to the customer. Under the cost-to-cost method, the

F-29


 

extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation.

The total transaction price for the 2019 LCA, was determined as $15.4 million at inception of the contract, consisting of the upfront payment, was effectively a licensing fee for the first molecule and research and development services for the second molecule. Variable consideration to be paid to the company upon reaching certain milestones had been excluded from the calculation, as at the inception of the contract, it was not probable that a significant reversal of revenue recognized would not occur in a subsequent reporting period.

There were two components identified in the 2020 Amendment, each of which was accounted for as a separate performance obligation. The first component, the grant of the additional options to acquire intellectual property rights for the third and fourth molecule, was deemed to be distinct, as the customer can benefit from it on its own, and it is independent of the delivery of other performance obligations in the 2019 LCA. The initial transaction price of the amendment was deemed by management to be zero at inception.

The second component, which allowed the customer to exercise its option to acquire intellectual property rights to the second molecule early, is considered to be a modification of the 2019 LCA. This is because the option is not independent of the research and development services provided under the 2019 LCA, and therefore the goods and services are not distinct. All performance obligations under the May 13, 2019 agreement in respect of the second molecule were deemed to have been fully satisfied on July 15, 2020. The Company updated the transaction price to $22.4 million on inception of the amendment, due to the addition of $8.5 million for the option exercise for the second molecule and a reduction in research and development services of $1.5 million, due to the early termination of the services.

During the year ended December 31, 2020, $9.9 million was recognized over time in respect of the single performance obligation relating to the second molecule, which consisted of the $8.5 million option exercise fee and $1.4 million in research and development services.

During the year ended December 31, 2021, Ares provided notice of its intention to exercise its option granted under the 2020 Amendment to acquire the intellectual property rights for the third molecule, and $2.7 million was recognized at a point in time in respect of the option exercise.

On January 3, 2022, Ares provided notice of its intention to exercise its option granted under the 2020 Amendment to acquire the intellectual property rights for the fourth molecule. An option fee of $2.6 million is payable upon option exercise.

License and collaboration agreement with Denali Therapeutics Inc.

Summary

In August 2016 the Company entered into an exclusive license and collaboration agreement (the “Denali LCA”) with Denali. Under the terms of the Denali LCA, Denali was granted the right to nominate up to three Fcab targets for approval (“Accepted Fcab Targets”), within the first three years of the date of the agreement. Upon entering into the Denali LCA, Denali had selected Transferrin receptor as the first Accepted Fcab Target and paid an upfront fee of $5.5 million to the Company. In May 2018, Denali exercised its right to nominate two additional Fcab targets and identified a second Accepted Fcab Target. Denali made a one-time payment to the F-star group for the two additional Accepted Fcab Targets of $6.0 million and extended the time period for its selection of the third Accepted Fcab Target until August 2020.

Under the terms of the agreement the Company is entitled to receive contingent payments that relate to certain defined preclinical, clinical, regulatory, and commercial milestones with a maximum value of $49.5 million.

Revenue recognition

The Company has considered the performance obligations identified in the contracts and concluded that the grant of intellectual property rights is not distinct from the provision of R&D services, as the R&D services are expected to significantly modify the early-stage intellectual property. As a result, the grant of intellectual property rights and the provision of R&D services has been combined into a single performance obligation for this contract.

F-30


 

The initial transaction price for first Accepted Fcab Target was deemed to be $7.1 million consisting of $5.0 million for the grant of intellectual property rights and $2.1 million for R&D services. The initial transaction price for the second Accepted Fcab target was $5.1 million, consisting of $3.0 million for the grant of intellectual property rights and $2.1 million for R&D services. During the year ended December 31, 2019, the transaction price for the first Accepted Fcab was increased to $8.6 million due to achievement of a $1.5 million milestone that on initial recognition of the Denali LCA was not included in the transaction price, as it was not deemed probable that a reversal would not occur in a future reporting period.

All performance obligations were deemed to have been fully satisfied during the year ended December 31, 2019 in respect of the first Accepted Fcab Target, and during the three months ended March 30, 2021 in respect of the second Accepted Fcab Target. As a result, no revenue was recognized in respect of the first accepted target for the years ended December 31, 2021 and 2020. In respect of the second Accepted Fcab Target for the years ended December 31, 2021 and 2020, the Company recognized $0.1 million and $1.3 million, respectively.

2021 Agreement with AstraZeneca

Summary

On July 7, 2021 the Company entered into a License Agreement with AstraZeneca AB. Under the terms of the agreement the Company has granted an exclusive license to certain patents and know-how to develop, manufacture and commercialize STING inhibitor compounds. AstraZeneca will be responsible for all future research, development and commercialization activities.

For the exclusive rights granted, an initial upfront fee of $0.5 million was paid by AstraZeneca to the Company during the three months ended September 2021. The Company is entitled to receive additional contingent near-term preclinical milestones of $11.5 million, plus maximum contingent payments that relate to certain defined development and regulatory milestones of $85.0 million and commercial milestones of $221.3 million, as well as royalty payments based upon a single digit percentage on net sales of products developed. Pursuant to the STING Antagonist CVR Agreement, 80% of net proceeds received the Company under the License Agreement with AstraZeneca will be payable, pursuant to the Exchange Agreement, to common stockholders of Spring Bank as of November 19, 2020, immediately prior to the Closing of the transaction.

Revenue recognition

Management has identified a single performance obligation in the contract, which is the grant of intellectual property rights.

The total transaction price was initially determined to be $0.5 million, consisting only of the upfront payment. Variable consideration to be paid to the company upon reaching certain milestones has been excluded from the calculation, as at the inception of the contract, it is not probable that a significant reversal of revenue recognized would not occur in a subsequent reporting period. The transaction price was allocated to the single performance obligation, which was deemed to be fully satisfied on the grant of intellectual property rights, and therefore the initial upfront fee was recognized at a point in time.

In the year ended December 31, 2021, the Company recorded revenue of $0.5 million in respect of this contract.

 

2021 License and Collaboration Agreement with Janssen Biotech, Inc.

 

On October 19, 2021, we entered into a license and collaboration agreement (the “Janssen Agreement”) with Janssen Biotech, Inc., one of the Janssen Pharmaceutical Companies of Johnson & Johnson. The Janssen Agreement was facilitated by Johnson & Johnson Innovation.

 

Under the Janssen Agreement, Janssen received a worldwide exclusive license to research, develop and the option to commercialize up to five novel bispecific antibodies directed to Janssen therapeutic targets using F-star’s proprietary Fcab and mAb2 platforms. Janssen is responsible for all research, development, and commercialization activities under the agreement.

 

F-star received or is entitled to receive upfront fees of $17.5 million, and near-term fees and potential further milestones of up to $1.35 billion. F-star is also eligible to receive potential tiered mid-single digit royalties on annual net sales of any products that receive regulatory approval and are commercialized using the licensed technology.

F-31


 

Revenue recognition

The Company assessed the arrangement in accordance with ASC 606 and concluded that Janssen is a customer based on the arrangement structure. The Company identified a single performance obligation under the arrangement consisting of the grant of intellectual property rights at the inception of the contract. There are no R&D services included in the arrangement or needed for Janssen to use the technology.

 

Revenue is recognized as functional IP, at the point in time control of the license is transferred.

 

The Company determined that the transaction price at the onset of the arrangement is the total upfront payment received in the amount of $17.5 million. The transaction price was allocated to the single performance obligation, which was deemed to be fully satisfied upon the grant of intellectual property rights, and therefore the initial upfront fee was recognized at a point in time. Separately, we also identified customer options, which include our obligations to grant an additional 18-month period to the research license granted at contract inception and to grant exploitation licenses for up to five Subject mAb2 molecules. These options do not represent a material right, as they are not offered at a significant and incremental discount and will be recorded as separate contracts when and if they are executed.

In the year ended December 31, 2021, the Company recorded revenue of $17.5 million in respect of this contract.

Summary of Contract Assets and Liabilities

Up-front payments and fees are recorded as deferred revenue upon receipt or when due until such time as the Company satisfies its performance obligations under these arrangements. A contract asset is a conditional right to consideration in exchange for goods or services that the Company has transferred to a customer. Amounts are recorded as accounts receivable when the Company’s right to consideration is unconditional.

The Company is subject to corporate taxation in the United Kingdom, United States and Austria. The Company’s income tax benefit in the year ended December 31, 2021 is mainly the result of changes in the deferred tax liability offset by US federal, state taxes and foreign tax charges. The income tax benefit in the year ended December 31, 2020 is mainly the result of US federal branch taxes and a prior year adjustment in Austria. The components of net (loss)/profit before tax provision from income taxes are as follows (in thousands):

The Company is subject to the corporate tax rate in the United States, United Kingdom and Austria. In the year ended December 31, 2021 the Company was subject to the rate of corporate tax in the United States (21%) due to the ultimate parent entity (FTI) being US-domiciled. The Finance Bill 2021 had its third reading on May 24, 2021 and is now considered

F-33


 

to be substantively enacted. This means that the 25% main rate of UK corporation tax and marginal relief will be relevant for any asset sale or timing differences expected to reverse on or after April 1, 2023.

The benefit for income taxes shown on the consolidated statements of operations differs from amounts that would result from applying the statutory tax rate to income before taxes primarily because of certain non-deductible expenditures, net operating losses adjustment for 382 limitation, and the change in the Company's valuation allowance on its deferred tax assets.

The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realization of deferred tax assets requires significant judgment. In determining whether its deferred tax assets are more likely than not realizable, the Company evaluated all available positive and negative evidence, and weighed the evidence based on its objectivity. After consideration of the evidence, including forecasts and strategic plans, management has concluded that it is more likely than not that the Company will not realize the benefits of its deferred tax assets and accordingly the Company has provided a valuation allowance for the full amount of the net deferred tax assets. The release of the valuation allowance would result in the recognition of certain deferred tax assets and an increase to the benefit for income taxes for the period the release is recorded. However, the exact timing and amount of the valuation allowance release are subject to change on the basis of the level of profitability that the Company is able to actually achieve.

Management has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets, and has determined that it is more likely than not that the Company will not recognize the benefits of its federal, state, and foreign deferred tax assets, and as a result, a valuation allowance of $35.2 million and $49.3 million has been established at December 31, 2021, and 2020, respectively. In the year ended December 31, 2021 the decrease in the valuation allowance was $14.0 million. At December 31, 2021, the Company had federal, state, and foreign NOL carryforwards of $81.3 million, $79.8 million, and $34.9 million, respectively, which expire beginning in 2029. The Company's unsurrendered U.K. net operating losses, and its U.S. federal net operating losses generated after December 31, 2017, do not expire. U.K. losses may be utilized to offset future taxable profits, subject to numerous utilization criteria and restrictions. The amount that can be offset each year is limited to £5.0 million plus an incremental 50% of U.K. taxable profits. As of December 31, 2021, the Company had federal and state research and development tax credit carryforwards of $0.3 million and $0.4 million respectively, which expire beginning in 2032.

The Internal Revenue Code of 1986, as amended (the Code), provides for a limitation of the annual use of net operating losses and other tax attributes (such as research and development tax credit carryforwards) following certain ownership changes (as defined by the Code) that could limit the Company’s ability to utilize these carryforwards. The Company completed a study to assess ownership changes under Section 382 of the Code during the year ended December 31, 2021. The results of the study indicated that $56.0 million of the Company's accumulated NOLs are projected to expire before utilization.

The Company recognizes, in its consolidated financial statements, the effect of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company had no uncertain tax positions during the years ended of December 31, 2021, and 2020. There are no amounts of interest or penalties recognized in the consolidated statements of operations or accrued on the consolidated balance sheet for any period presented. The Company does not expect any material changes in these uncertain tax benefits within the next 12 months.

The Company files income tax returns in the United Kingdom, Austria, and the United States for federal income taxes and in Massachusetts for state income taxes. In the ordinary course of business, the Company is subject to examination by tax authorities in these jurisdictions. The 2019 and 2020 tax year remains open to examination by HM Revenue & Customs. The statute of limitations for assessment with the Internal Revenue Service is generally three years from filing of the tax return; however, all of the Company’s tax years remain open to examination in the United States, as carryforward attributes generated in past years may still be adjusted upon examination by the Internal Revenue Service or state tax authorities if they have or will be used in future periods. The statute of limitations for assessment with the Austrian tax authorities is a period of five years following the end of each fiscal year. Therefore, all fiscal years from 2017 to 2020 remain open for assessment. The Company is currently not under examination by any jurisdictions for any tax years.

The Company recognizes, in its consolidated financial statements, the effect of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination.

Diluted net loss per common share is the same as basic net loss per common share for all years presented.

The Company’s potentially dilutive securities, which include share options and warrants to subscribe for ordinary

shares have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted average number of ordinary shares outstanding used to calculate both basic and diluted net loss per share is the same. For the year ended December 31, 2021, and December 31, 2020, the weighted average number of potentially dilutive shares was 603,348 and 709,591 respectively.
