Overview

Aravive, Inc. (“Aravive” or the “Company”) was incorporated on December 10, 2008 in the State of Delaware. Aravive Biologics, Inc. (“Aravive Biologics”), our wholly owned subsidiary, was incorporated in 2007. We are a clinical-stage oncology company developing transformative treatments designed to halt the progression of life-threatening diseases, including cancer and fibrosis.

Batiraxcept (formerly AVB-500), is an ultrahigh-affinity, decoy protein that targets the GAS6-AXL signaling pathway. By capturing serum GAS6, batiraxcept starves the AXL pathway of its signal, potentially halting the biological programming that promotes disease progression. AXL receptor signaling plays an important role in multiple types of malignancies by promoting metastasis, cancer cell survival, resistance to treatments, and immune suppression.

Our current development program benefits from the availability of a proprietary serum-based biomarker that has accelerated batiraxcept drug development by allowing us to select a pharmacologically active dose and may potentially identify the cancer patients that have the best chance of responding to batiraxcept.

In our completed Phase 1 clinical trial in healthy volunteers with batiraxcept, we have demonstrated proof of mechanism for batiraxcept in neutralizing GAS6. Importantly, batiraxcept had a favorable safety profile preclinically and in the first in human trial and Phase 1b clinical trial in cancer patients.

In August 2018, the U.S Food and Drug Administration (the “FDA”) designated as a Fast Track development program the investigation of batiraxcept, for platinum-resistant recurrent ovarian cancer (“PROC”).

In December 2018, we initiated our Phase 1b clinical trial of batiraxcept combined with standard of care therapies in patients with PROC, for which we reported results in July 2020.

In April 2020, we entered into a license and collaboration agreement with WuXi Biologics (Hong Kong) Limited (“WuXi”), the objective of which is to identify and develop novel high-affinity bispecific antibodies against CCN2, also known as connective tissue growth factor (“CTGF”), implicated in cancer and fibrosis and identified from a similar target discovery screen that identified the significance of the AXL/GAS6 pathway in cancer. However, in August 2022, we temporarily halted work on the CTGF program with WuXi in an effort to focus all our resources on ongoing clinical programs.

In November 2020, we entered into the collaboration and license agreement with 3D Medicines Inc. (the “3D Medicines Agreement”), whereby we granted 3D Medicines an exclusive license to develop and commercialize products that contain batiraxcept as the sole drug substance, for the diagnosis, treatment or prevention of human oncological diseases, in China, Taiwan, Hong Kong and Macau (the “Territory”).

During the fourth quarter of 2020, we initiated our Phase 1b portion of the Phase 1b/2 trial of batiraxcept in clear cell renal cell carcinoma (“ccRCC”) and we dosed our first patient in the trial in March 2021.

During the first quarter 2021, we initiated our registrational Phase 3 trial of batiraxcept in PROC and we dosed our first patient in the trial in April 2021.This global, randomized, double-blind, placebo-controlled trial is designed to evaluate efficacy and safety of batiraxcept at a dose of 15 mg/kg in combination with paclitaxel (“PAC”) versus PAC alone.

In May 2021, we announced expansion of batiraxcept development programs into first line pancreatic ductal adenocarcinoma (“PDAC”) with the goal of initiating the trial by end of 2021. We dosed our first patient in August 2021.

In June 2021, we announced initial safety, pharmacokinetic (“PK”), and pharmacodynamic (“PD”) results from the batiraxcept Phase 1b portion of the Phase 1b/2 clinical trial in ccRCC.

In October 2021, the EMA granted orphan drug designation for batiraxcept for the treatment of PROC, following a recommendation from the Committee for Orphan Medicinal Products.

In November 2021, we announced preliminary data from our Phase 1b trial evaluating batiraxcept in combination with cabozantinib for treatment of ccRCC.

In January 2022, we announced that we had dosed the first patient in the Phase 2 portion of the Phase 1b/2 study of batiraxcept in combination with cabozantinib for treatment of ccRCC.

In March 2022, we announced updated data and new biomarker data from our Phase 1b trial of batiraxcept in ccRCC.

In May 2022, we provided updated data and information at our Key Opinion Leader symposium.

In October 2022, we received a $6 million development milestone payment from 3D Medicines based on the initiation of the global Phase 3 PROC clinical trial in their Territory.

In November 2022, the FDA designated as a Fast Track development program the investigation of batiraxcept for treatment of patients with advanced or metastatic ccRCC who have progressed after 1 or 2 prior lines of systemic therapy that include both immuno-oncology (“IO”)-based and vascular endothelial growth factor tyrosine kinase inhibitor (“VEGF-TKI”)-based therapies (either in combination or sequentially).

In January 2023, we announced complete enrollment in the global Phase 3 PROC clinical trial.

In February 2023, we presented updated Phase 1b/2 ccRCC data at the 2023 American Society of Clinical Oncology (ASCO) Genitourinary (GU) Cancers Symposium, taking place February 16-18, 2023 in San Francisco and virtually.

In February 2023, we announced that the FDA granted orphan drug designation to batiraxcept for the treatment of PDAC.

First Oncology Indication - Ovarian Cancer and Current Market Opportunity

The decision to select high grade platinum-resistant recurrent ovarian cancer ("PROC") as our first indication was based upon the preclinical data that we generated with batiraxcept in PROC, the fact that high grade serous ovarian cancer tumors are highly AXL positive and the high unmet medical need for effective therapies to treat PROC. In August 2018, the FDA granted Fast Track Designation to batiraxcept for PROC.

Ovarian cancer ranks fifth in cancer deaths among women in the U.S., accounting for more deaths than any other cancer of the female reproductive system.  According to the American Cancer Society, it is estimated that in 2023 there will be approximately 19,710 new cases of ovarian cancer diagnosed in the United States and approximately 13,270 ovarian cancer deaths in the United States. A woman’s risk of getting ovarian cancer during her lifetime is about 1 in 78. Her lifetime chance of dying from ovarian cancer is about 1 in 108.  Due to the nonspecific nature of disease symptoms, currently approximately 70% of ovarian cancer patients are diagnosed with advanced-stage disease, at which point their prognosis is poor. Improving the ability to detect ovarian cancer early is a research priority, given that women diagnosed with localized-stage disease have more than a 90% five-year survival rate.

Decision Resources Group, LLC ("DRG") in its January 2021 Key Findings in Ovarian Cancer, Disease Landscape and Forecast Report estimates the total ovarian cancer market to grow in the major markets (United States, France, Germany, Italy, Spain, the United Kingdom and Japan) at an annual rate of 12.5% from nearly $3 billion in 2019 to nearly $10 billion in 2029.

Treatment of PROC patients (patients whose disease progresses within 6 months of their last platinum-based therapy) on their second- and third-line of therapy consists of a nonplatinum monotherapy as sequential single-agent salvage chemotherapy has been shown to be superior to multiagent chemotherapy in this setting (DRG- December 2019 Ovarian Cancer Disease Landscape and Forecast). Widely used single-agent therapies in this population include gemcitabine, pegylated-liposomal doxorubicin, topotecan, and PAC with or without bevacizumab or Avastin. The median progression free survival (“PFS”) rate for patients given standard of care (PAC or doxil/pegylated liposomal doxorubicin (“PLD”)) to treat platinum-resistant recurrent ovarian cancer is 3-4 months, with a median overall survival (“OS”) of 9-12 months (A. Davis et al. / Gynecologic Oncology 133 (2014) 624–631).  Adding bevacizumab to the chemotherapy resulted in a median PFS of 6.7 months (Pujade-Lauraine, et al., J Clin Oncol 32:1302-1308) but there was no OS benefit (Stockler MR, et al. J Clin Oncol. 2014 May 1;32(13):1309-16). In the United States, another treatment option in third-line platinum-resistant/refractory ovarian cancer are poly ADP ribose polymerase inhibitors ("PARPi") which are indicated as a monotherapy for the treatment of patients with deleterious BRCA mutation (germline and/or somatic) with advanced ovarian cancer who have been treated with two or more chemotherapies. There is no standard of care for patients with non-BRCA mutated/ HR proficient ovarian cancer in the fourth- and subsequent-line settings. The majority of these patients have become platinum-resistant and are typically managed with monotherapy chemotherapy treatments.

Data from the Phase 1a and 1b Clinical Trials of Batiraxcept

The safety of batiraxcept was studied in 84 subjects, including 31 healthy volunteers in a Phase 1a clinical trial and 53 PROC patients in a Phase 1b clinical trial (40 in 10 mg/kg cohort, 6 in 15 mg/kg cohort, and 7 in 20 mg/kg cohort).

In December 2018, following a normal healthy volunteer trial that identified a dose of 10mg/kg batiraxcept as sufficient to suppress serum GAS6 levels for a two-week period, we began treating patients in our Phase 1b clinical trial combining 10mg/kg (administered every 2 weeks) batiraxcept with standard-of-care therapies (specifically, PAC or PLD) in patients with PROC. The Phase 1b clinical trial was designed, in part, to confirm the dosing regimen predicated on the Phase 1 trial in healthy volunteers and to identify the dose to investigate in later stage trials. The primary objective of the Phase 1b clinical trial was to assess the safety and tolerability of batiraxcept in combination with PAC or PLD, and secondary objectives were to assess PK and PD (serum GAS6 and soluble AXL (“sAXL”) levels), efficacy, and potential immunogenicity of batiraxcept. Exploratory objectives included efficacy endpoints in biomarker (GAS6, AXL) defined populations based on expression of those biomarkers in serum and/or tumor tissue.

Safety Data: Batiraxcept has been generally well-tolerated with no dose-limiting toxicities or unexpected safety signals. There were no batiraxcept-related significant adverse events reported. There were two types of adverse events reported in the Phase 1b PROC trial that were considered related to batiraxcept, as determined by an independent medical monitor: infusion reactions and fatigue.  A premedication regimen was designed and implemented during the trial to manage potential infusion reactions.

Pharmacokinetics: Prior data analysis of 31 PROC patients from the 10 mg/kg cohort showed that blood trough levels of batiraxcept taken on Cycle 1 Day 15 ("C1D15") demonstrated statistically significant correlation with clinical activity, as patients who achieved minimal efficacious concentration (“MEC”) >13.8 mg/L demonstrated a greater likelihood of response and prolonged PFS. Updated modeling using actual data from all enrolled patients demonstrated that the 20 mg/kg dose is not predicted to improve PFS relative to the 15 mg/kg dose so the dose of 15 mg/kg was selected as the recommended Phase 2 dose or RP2D for batiraxcept.

Clinical Activity: While the Phase 1b clinical trial was a safety trial and not powered to demonstrate efficacy, the investigator-assessed best response according to RECIST V1.1 to batiraxcept across all cohorts supports promising clinical activity.  In September 2019, we presented data from the initial 12 patients of the Phase 1b clinical trial in a late breaking oral presentation at the European Society for Medical Oncology Congress in Barcelona and based upon our analysis of the data decided to study higher doses of the drug and expanded the Phase 1b trial to study 15 mg/kg and 20 mg/kg dose levels.

The Phase 1b study data are summarized as follows:

Clinical Activity Data for 10mg/kg and 15mg/kg Patients whose First Trough Level was Above the MEC of 13.8mg/L

Phase 3 Registrational Trial Design in PROC

On November 19, 2020, we announced that we had received guidance from the FDA on a registrational Phase 3 trial design for batiraxcept in PROC. The FDA feedback received was that this trial, if successful, could support full approval of batiraxcept for the treatment of PROC. No further preclinical or clinical pharmacology studies are required at this time. The global, randomized, double-blind, placebo-controlled trial is being conducted at approximately 155 sites in the U.S., Canada, China, and Europe and designed to evaluate efficacy and tolerability of batiraxcept at a dose of 15 mg/kg in combination with PAC in patients with high-grade serous ovarian cancer who have received one to four prior lines of therapy.  The pivotal Phase 3 trial initiated in April 2021 and achieved full enrollment of over 360 patients early January 2023. The primary endpoint for the trial is PFS, and secondary endpoints include OS, ORR based on RECIST 1.1, safety and tolerability, DoR, quality of life, clinical benefit rate, and PK and PD profile. Exploratory biomarkers include serum GAS6, serum sAXL and batiraxcept drug levels.

The registration-directed Phase 3 program of batiraxcept in combination with paclitaxel in PROC remains on track. We expect to report topline data from the trial by mid-2023 depending on the time the required number of PFS events occur for data analysis. Chemistry, manufacturing and control (“CMC”) work remains on track with the goal of submitting a Biologics License Application (“BLA”) by year-end 2023. The global, randomized, double-blind, placebo-controlled Phase 3 trial is evaluating efficacy and tolerability of batiraxcept at a dose of 15 mg/kg in combination with paclitaxel versus placebo in combination with paclitaxel.

Phase 3 batiraxcept -OC-004 Design

Second Oncology Indication - ccRCC

ccRCC and Current Market Opportunity

The decision to select ccRCC as our second indication was based upon the strong preclinical data that we generated with batiraxcept and the fact that AXL expression in primary tumors of ccRCC patients has been shown in third party studies as well as our own studies (Rankin et al, PNAS September 16, 2014 vol. 111 no. 37 13373–13378), to correlate with aggressive tumor behaviors.

Kidney cancer is a leading cause of cancer-related deaths in the United States and is among the 10 most common cancers in both men and women. Metastasis to distant organs including the lung, bone, liver and brain is the primary cause of death in kidney cancer patients as only 12% of metastatic kidney cancer patients will survive past 5 years. According to the American Cancer Society, it is estimated that there will be approximately 81,800 new cases of kidney cancer and 14,890 people will die from this disease in the United States during 2023.

ccRCC is a cancer of the kidney. The name "clear cell" refers to the appearance of the cancer cells when viewed with a microscope. ccRCC occurs when cells in the kidney quickly increase in number, creating a lump (mass). Though the exact cause of ccRCC is unknown, smoking, excessive use of certain medications, and genetic predisposition conditions, e.g., von Hippel Lindau syndrome which involves genetic mutation in VHL, a tumor suppressor gene controlling tumor initiation in ∼90% of ccRCC tumors, may contribute to the development of this type of cancer.

Treatment often begins with surgery to remove as much of the cancer as possible, and may be followed by radiation therapy, chemotherapy, biological therapy, or targeted therapy. Most kidney cancer is chemotherapy and radiation resistant, resulting in a large unmet need for treatment options. As reported in Decision Resources Group, LLC’s December 2019 Report on The Landscape & Forecast of Renal Cell Carcinoma, nivolumab and cabozantinib have experienced strong uptake as second-line therapies since their FDA approvals (in 2015 and 2016, respectively). However, DRG anticipates that nivolumab’s second-line patient shares, across the major markets, will begin to decline from 29-35% in 2018 to 22-27% in 2028, in part owing to its first-line label expansion in combination with ipilimumab and then later as other combination regimens with PD-1/PD-L1 inhibitors enter the first-line setting. In contrast, cabozantinib’s second-line patient share as monotherapy is expected to steadily increase over the forecast period as its use in the first-line setting correspondingly declines, and it solidifies its position as the treatment of choice following a first-line immune checkpoint inhibitor combination. By 2023, it is estimated by DRG that cabozantinib will overtake nivolumab as the second-line sales and patient-share leader in all major markets; in 2028, it is expected to earn patient shares of 31-43% across the major markets. Similarly, DRG expects axitinib’s second-line patient share will decline over the forecast period, corresponding to the uptake of cabozantinib and the notable uptake of pembrolizumab plus axitinib in the first-line setting; its major-market patient shares will then stabilize to 6-16% between 2024 and 2028. These assumptions in renal cell carcinoma suggest the greatest need may be with respect to second line therapies and in combination with cabozantanib.  

Phase 1b/ 2 Clinical Trial

In February 2019, we announced our plans to develop batiraxcept in our second oncology indication, ccRCC. On January 13, 2020, we announced that we had received FDA clearance of our Investigational New Drug Application (“IND”) for investigation of batiraxcept, for treatment of patients with advanced or metastatic ccRCC who progressed with or were intolerant to front-line treatment.

Phase 1b/2 Trial Designed to Accelerate Development in ccRCC

The Phase 1b trial is evaluating batiraxcept at doses of 15 mg/kg and 20 mg/kg, plus cabozantinib 60 mg daily in previously treated (2L+) patients with ccRCC. Prior treatment with cabozantinib is not allowed. The primary objective is safety; secondary and exploratory objectives include identification of the recommended Phase 2 dose (“RP2D”), ORR, and DoR. Given baseline levels of serum sAXL/GAS6 correlated to clinical activity in our Phase 1b trial of batiraxcept in PROC, one of the objectives of the ccRCC trial is to correlate baseline sAXL/GAS6 with response in patients with ccRCC treated with batiraxcept plus cabozantinib. We dosed two cohorts of patients, one at the 15 mg/kg dose and the second at 20mg/kg dose. A review of the Phase 1b data demonstrates that 15mg/kg batiraxcept is an appropriate dose to suppress serum GAS6 levels in these patients being treated with cabozantinib and that 20mg/kg batiraxcept does not provide additional clinical activity beyond that seen with 15mg/kg batiraxcept, consistent with the modeling done using the Phase 1b PROC data.

In January 2022, we announced the first patient was dosed in the Phase 2 portion of the ccRCC trial. The Phase 2 portion of the Phase 1b/2 clinical trial of batiraxcept in ccRCC is an open-label study in which 55 patients are anticipated to enroll across three parts. Part A is expected to enroll approximately 25 patients and will investigate batiraxcept 15 mg/kg in combination with cabozantinib in 2L+ ccRCC patients. Part B is expected to enroll approximately 20 patients and evaluate batiraxcept 15 mg/kg in combination with standard of care nivolumab and cabozantinib in first-line ccRCC patients. Part C is expected to evaluate batiraxcept 15 mg/kg monotherapy in approximately 10 patients with ccRCC who are not eligible for curative intent therapies. The primary endpoint of each part of the Phase 2 portion of the trial is ORR and key secondary endpoints include DoR, PFS, and OS. The Phase 2 portion of the ccRCC clinical trial will also explore batiraxcept effects on biomarkers (sAXL and GAS6) in serum.

By August 8, 2022, 26 previously treated (2L+) patients with ccRCC had been treated with batiraxcept in the Phase 1b portion of the Phase 1b/2 trial at doses of 15 mg/kg (n=16) and 20 mg/kg (n=10), plus cabozantinib 60 mg daily. There were no dose limiting toxicities observed at either dose. The best overall response rate (ORR, confirmed) in the Intent to treat (“ITT”) population was 42%. One of the objectives of the ongoing Phase 1b/2 ccRCC trial is to evaluate the correlation of baseline serum sAXL/GAS6 (biomarker) with radiographic response in patients with ccRCC treated with batiraxcept plus cabozantinib. The best ORR in the biomarker high population was 55%. The 9-month progression-free survival (PFS) rate was 65% in the ITT population and 72% in the biomarker high population. We discussed a registrational path with the FDA that includes use of the sAXL/Gas6 ratio as a basis for a potential accelerated approval.

On November 29, 2022, we announced that the FDA has granted Fast Track Designation to batiraxcept, for treatment of patients with advanced or metastatic ccRCC who have progressed after 1 or 2 prior lines of systemic therapy that include both IO-based and VEGF-TKI-based therapies (either in combination or sequentially).

Fast Track is a process designed to facilitate the development and expedite the review of investigational drugs to treat serious conditions and fill an unmet medical need. Drugs that receive Fast Track designation may be eligible for more frequent communications and meetings with the FDA to discuss the drug's development plan, including the design of the proposed clinical trials, use of biomarkers and the extent of data needed to support approval. Drugs with Fast Track Designation may also qualify for accelerated and priority review of new drug applications if relevant criteria are met.

The Fast Track Designation was based on new data submitted to the agency from the Phase1b portion of the Phase 1b/2 ccRCC study (AVB500-RCC-003; NCT04300140) in September. As of September 26, 2022, 26 previously treated (second line or greater) patients with ccRCC have been treated with batiraxcept in the Phase 1b portion of a Phase 1b/2 trial at doses of 15 mg/kg (n=16) and 20 mg/kg (n=10), plus cabozantinib 60 mg daily. There were no dose limiting toxicities observed at either dose. Clinical data from this study demonstrate that batiraxcept has the potential to increase the clinical activity of cabozantinib in patients with metastatic ccRCC who have progressed following IO- and VEGF-TKI-based therapies (N=14 of the 26 patients) as the ORR was 57% and median PFS was 11.4 months in this population.

Anticipated Batiraxcept Phase 2/3 Trial Design in ccRCC

Based on data provided in the first quarter of 2022, the FDA recommended an integrated Phase 2/3 study with interim analyses to look at futility in the biomarker low population and ORR for potential accelerated approval with PFS endpoint for full approval. This study design provides an opportunity for both accelerated approval and confirmatory approval in one study and potentially increases the chance for success by allowing the final PFS analysis to be conducted in the ITT and the biomarker high population. Given the most recent data in September and fast-track designation, we plan to also analyze the patients with advanced or metastatic ccRCC who have progressed after both IO-based and VEGF-TKI-based therapies (either in combination or sequentially). The full protocol and statistical plan are in preparation for submission to the FDA.

We expect to report additional data from the Phase 1b portion and preliminary data from the Phase 2 portion of the ccRCC trial mid-2023.  We anticipate initiating the registrational Phase 2/3 trial in the second half of 2023.

Third Oncology Indication - PDAC

Phase 1b Design in 1L Pancreatic Adenocarcinoma

The pancreas is a gland about 6 inches long that is shaped like a thin pear lying on its side and it is in the abdomen near the stomach, intestines, and other organs. The pancreas has two main jobs in the body: 1) to make juices that help digest (break down) food; and 2) to make hormones, such as insulin and glucagon, that help control blood sugar levels. Both of these hormones help the body use and store the energy it gets from food. The digestive juices are made by exocrine pancreas cells and the hormones are made by endocrine pancreas cells. About 95% of pancreatic cancers begin in exocrine cells and the most common pancreatic exocrine tumors are called adenocarcinomas. 

Pancreatic cancer is the third deadliest cancer in the US and has the highest mortality rate of all cancers, with a five-year survival rate of 11% (The Surveillance, Epidemiology, and End Results (SEER) Website)). Few patients are candidates for curative treatment, as the cancer has usually metastasized at the time of diagnosis. Chemotherapy has limited benefit, due to the dense dysplastic stroma impeding delivery and the rapid development of resistance. Immunotherapy also has a limited role as pancreatic cancer has a highly immunosuppressive microenvironment. (Nevala-Plagemann C, Hidalgo M, Garrido-Laguna I. From state-of-the-art treatments to novel therapies for advanced-stage pancreatic cancer. Nat Rev Clin Oncol. Feb 2020;17(2):108-123. doi:10.1038/s41571-019-0281-6).The American Cancer Society estimates 64,050 people will be diagnosed with pancreatic cancer and 50,550 people will die of pancreatic cancer in 2023. Per AACR, pancreatic cancer is projected to become the third leading cause of cancer death worldwide by 2025 and the second leading cause of cancer death in the U.S. by 2040(Rahib L, Wehner MR, Matrisian LM, Nead KT. Estimated Projection of US Cancer Incidence and Death to 2040. JAMA Netw Open. Apr 1 2021;4(4):e214708. doi:10.1001/jamanetworkopen.2021.4708).

Decision Resources Group, LLC in its December 2019 Pancreatic Cancer Disease Landscape and Forecast reports the first-line metastatic population is the largest drug-treatable population in pancreatic cancer. Correspondingly, the first-line metastatic population had the highest therapy sales ($901 million in 2018, with all but 62 million from the pancreatic exocrine tumor population), accounting for 53% of the total pancreatic cancer therapy market. By 2028, these sales are expected to fall short by more than $100 million ($764 million in 2028), mainly because most products prescribed for metastatic pancreatic adenocarcinoma in the first-line have become generically available and due to failures of several highly anticipated late-phase pipeline drugs.  However, there is a clear need for additional therapies and there is a clear trend developing towards a combinatorial approach as a substantial percentage of early-phase studies are being conducted with two or more investigational agents. The addressable population (i.e., eligible to receive gemcitabine + nab-paclitaxel as first-line treatment) across the US and 5 major EU regions is estimated to be approximately 38,000.

On August 9, 2021, we announced that we had dosed the first patient in the Phase 1b portion of our Phase 1b/2 of AVB-500 as a first-line therapy in combination with gemcitabine and nab-paclitaxel (Abraxane®) in patients with advanced or metastatic pancreatic adenocarcinoma eligible to receive gemcitabine and nab-paclitaxel combination therapy. The Phase 1b portion of the clinical trial is evaluating safety, tolerability, PK, PD, and clinical activity in 21 patients dosed with 15 mg/kg of batiraxcept in combination with gemcitabine and nab-paclitaxel.

As of September 20, 2022, 18 patients with PDAC had been treated with 15 mg/kg (Days 1 & 15) + nab-paclitaxel (125 mg/m2 on Days 1, 8, & 15) and gemcitabine (1000 mg/m2 on Days 1, 8, & 15) and have PK data. As has been seen for other Phase 1b cancer studies with batiraxcept, there is a relationship between batiraxcept exposures and clinical activity such that 5 out of the 9 patients in the PDAC study whose batiraxcept levels exceeded the MEC of batiraxcept had a response vs 1 out of 9 patients in the below MEC group. Similarly, the mPFS in the above MEC group was 5.6 months (95% CI 2.1, not evaluable) vs 2.7 months (95% CI 1.1, 5.4) in the below MEC group. In May 2022, we had reported that batiraxcept in combination with gemcitabine and nab-paclitaxel was generally well-tolerated with no unexpected safety signals. Consistent with our other clinical trials, we noted a relationship between clinical activity and batiraxcept drug levels, however highly fibrotic tumors like PDAC may require higher batiraxcept concentrations than platinum-resistant ovarian cancer and clear cell renal cell cancer patients to reach the appropriate batiraxcept drug levels. Due to this characteristic of pancreatic cancer, we are testing higher doses of batiraxcept to see if we can increase the proportion of patients who benefit from the triplet regimen.

In February 2023, the FDA granted orphan drug designation ODD to batiraxcept for the treatment of PDAC.

Investigator Sponsored Trials

In May 2019, we entered into an institution sponsored clinical trial agreement with M.D. Anderson Cancer Center for the use of, and our supply of, batiraxcept, in combination with AstraZeneca Pharmaceuticals LP’s medicinal product durvalumab in a Phase 1/2 trial being conducted by the M.D. Anderson Cancer Center for the treatment of patients with platinum-resistant, recurrent epithelial ovarian cancer. Data from this study were presented at the 2022 Society of Gynecological Oncology (SGO) meeting in Arizona: Phase Ib study of AVB S6 500 in Combination with Durvalumab (MEDI4736) in Patients with Platinum Resistant, Recurrent Epithelial Ovarian Cancer (EOC).  This study has completed.

In March 2020, we announced that the first patient was dosed in a Phase 1/2 trial for the use of, and our supply of, batiraxcept, in combination with EMD Serono’s medicinal product avelumab being conducted by the University of Oklahoma for the treatment of patients with advanced urothelial cancer (COAXIN trial). Data from this study was presented at the 2022 ASCO meeting in Chicago: Phase Ib study of avelumab and novel AXL inhibitor AVB-S6-500 in patients with metastatic urothelial carcinoma (mUC), Abhishek Tripathi, Melissa Clingerman, Riza Celine Fabreo, Adanma Ayanambakkam, Brian Cross, Kelly Lynn Stratton, Michael Cookson, Sumanta K. Pal, and Neeraj Agarwal, Journal of Clinical Oncology 2022 40:16_suppl, 4579-4579.  One patient with a complete response remains on study as of end of 2022.

Strategic Collaborations

In April 2020, we entered into a license and collaboration agreement with WuXi, the objective of which is to identify and develop novel high-affinity bispecific antibodies against CCN2, also known as CTGF, implicated in cancer and fibrosis and identified from a similar target discovery screen that identified the significance of the AXL/GAS6 pathway in cancer. The goal is to generate a best-in-class therapeutic targeting desmoplasia and tumor growth in the clinic in 2023. In August 2022, we temporarily halted work on the CTGF program with WuXi in an effort to focus all our resources on ongoing clinical programs involving batiraxcept.

On November 6, 2020, we entered into the 3D Medicines Agreement, whereby we granted 3D Medicines an exclusive license to develop and commercialize products that contain batiraxcept as the sole drug substance for the diagnosis, treatment or prevention of human oncological diseases, in the Territory.

GAS6-AXL Pathway

As illustrated in the following graphic, AXL receptor signaling plays an important role in multiple types of malignancies by promoting metastasis, cancer cell survival, resistance to treatments, and immune suppression.  

Figure 6: GAS6 and AXL are Overexpressed in Many Cancers and Associated with Tumor Growth,

Metastasis, Drug Resistance, and Poor Survival

In preclinical studies, we have also identified high AXL expression on tumors resistant to the combination of radiotherapy and immunotherapy and that genetically inactivating AXL in tumors resistant to immunotherapy and radiotherapy restored anti-tumor immune response.

In preclinical studies conducted in Dr. Giaccia’s laboratories at Stanford University, Dr. Giaccia was able to demonstrate that the immune response generated by loss of AXL leads to adaptive immune resistance through PD-L1 expression and Treg (regulatory T cells) infiltration. This resulted in tumors that became sensitive to checkpoint immunotherapy when they were previously resistant. Thus, GAS6-AXL pathway inhibitors, in combination with radiation or chemotherapy and immunotherapy, may be a promising treatment regimen and may restore anti-tumor immune response.

Aravive-S6 (AVB-S6)

AVB-S6 is comprised of a family of novel, high-affinity, soluble Fc-fusion proteins, which include batiraxcept, designed to block the activation of the GAS6-AXL signaling pathway by intercepting GAS6 and interfering with its binding to its receptor AXL. AVB-S6 proteins have been engineered to have approximately 50- to 200-times greater affinity for human GAS6 compared to the native AXL receptor, effectively sequestering GAS6 and abrogating AXL signaling. We believe this ‘decoy receptor’ approach is well suited for AXL inhibition compared to small molecule receptor tyrosine kinase inhibitors or antibodies, as illustrated by the following graphic

Figure 7: Approaches to Inhibiting the GAS6/AXL Signaling Pathway

Preclinical Results

Our AVB-S6 proteins have been shown to bind GAS6 with higher affinity than the endogenous AXL protein and inhibit GAS6/AXL signaling. Initial preclinical pharmacology studies were conducted with a variety of engineered AVB-S6 proteins. The preclinical program demonstrated that high GAS6 binding affinity was critical and correlative with the ability of AVB-S6 to inhibit metastasis and disease progression in vivo. AVB-S6 proteins have demonstrated significant efficacy in mouse models of metastatic ovarian, breast, renal, and pancreatic cancers.

Biomarker

GAS6 expression in tumors has been reported to be an adverse prognostic factor in several cancers, including urothelial, ovarian, lung adenocarcinoma, gastric cancer, glioblastoma, oral squamous cell carcinoma, liver carcinoma, and renal cell carcinoma. In studies conducted by us, AVB-S6 proteins bind GAS6 with higher affinity than the endogenous AXL protein and prevent GAS6 signaling at the AXL receptor. Preclinical efficacy data for the AVB-S6 program demonstrated a relationship between reduced serum GAS6 and an anti-metastatic effect. We have developed an assay designed to measure GAS6 levels in the blood before and after dosing of our development candidate in humans. In the presence of a pharmacologically active dose of AVB-S6, serum GAS6 has not been detectable. Thus, GAS6 levels in the blood of patients is a PD biomarker that aids AVB-S6 dose selection and potentially serves as a predictive biomarker for response to treatment with AVB-S6. Additionally, our Phase1b PROC clinical trial identified a relationship between sAXL / GAS6 ratios as every patient that responded to treatment, regardless of chemotherapy being administered in combination, had a sAXL / GAS6 of >0.773. We will continue to explore these biomarkers in our other clinical trials.

The following graphic indicates the relationship between batiraxcept protein levels and GAS6 levels in blood from humans participating in the batiraxcept first in human trial.

Manufacturing

Manufacturing of our clinical trial material consists of three main phases, the production of bulk protein (drug substance), formulation/filling operations, and labelling/packaging operations of the finished product. The protein has been manufactured at high yield and with high purity. The clinical bulk drug substance is produced using industry standard manufacturing processes, as is the drug product.

Since September 2017, we have relied on WuXi, a third-party contract manufacturer to manufacture clinical bulk drug substance and drug product of batiraxcept using a cell line and process developed by our contract manufacturer that has been licensed to us on a non-exclusive basis. We have manufactured enough batiraxcept to dose patients through the planned Phase 3 PROC trial, our other ongoing clinical trials and support submission of the anticipated PROC BLA. The clinical bulk drug substance and drug product is manufactured pursuant to the terms of a five-year Master Manufacturing Services Agreement that we entered into with our contract manufacturer in July 2016, which automatically renews for successive one (1) year periods, unless either party provides written notice to the other party of its desire not to renew at least 90 days prior to the expiration of the then-current term.  The Master Manufacturing Services Agreement is terminable by us upon 45 days prior written notice, by our contract manufacturer upon 180 days prior written notice provided that all statements of work in progress at such time are completed and upon 60 days prior written notice upon a breach of the terms of the agreement if such breach is not cured within such 60-day period.

We have also contracted with an independent third party located in Texas for the labeling, packaging, and distribution of our injectable protein.

Our personnel have significant technical, manufacturing, analytical, quality and project management experience to execute and manage manufacturing process development, plus oversee the manufacture, testing, quality release, storage and distribution of drug products according to the current Good Manufacturing Practice (“cGMPs”), promulgated by the FDA and other regulatory requirements. The cGMP regulations include requirements relating to the 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. Our facilities, and our third-party manufacturers, may be subject to periodic inspections by FDA and local authorities, which include, but are not limited to procedures and operations used in the testing and manufacture of our biological drug candidates to assess our compliance with applicable regulations. Failure to comply with statutory and regulatory requirements subjects a manufacturer to possible legal or regulatory action, including warning letters, the seizure or recall of products, injunctions, and consent decrees causing significant restrictions on or suspending manufacturing operations plus causing possible civil and criminal penalties. These actions could have a material impact on the availability of its biological drug candidates. Similar to contract manufacturers, we may encounter difficulties involving production yields, quality control and quality assurance, as well as shortages of qualified personnel.

Research and Development

We have made and will continue to make substantial investments in research and development. Our research and development expenses totaled approximately $66.9 million and $37.5 million for the years ended December 31, 2022 and 2021, respectively.

In the ordinary course of business, we enter into agreements with third parties, such as CROs, medical institutions, clinical investigators and contract laboratories, to conduct clinical trials and aspects of research and preclinical testing. These third parties provide project management and monitoring services and regulatory consulting and investigative services.

Competition

The biotechnology and pharmaceutical industries are characterized by intense competition to develop new technologies and proprietary products. We face competition from many different sources, including biotechnology and pharmaceutical companies, academic institutions, government agencies, as well as public and private research institutions. Any products that we may commercialize will have to compete with existing products and therapies as well as new products and therapies that may become available in the future.

At this time, there are no FDA or EMA approved therapies targeting GAS6. We believe this mechanism of action represents a novel approach to inhibiting tumor growth and metastasis, as well as addressing tumor immune evasion and resistance to other anticancer agents. Exelixis, Inc. markets cabozantinib, a Tyrosine Kinase Inhibitor which is the only currently marketed compound that inhibits AXL in addition to inhibiting several other kinases. We are aware of a number of companies focused on developing AXL inhibitors in various indications, including BerGenBio ASA, Astellas Pharma Inc., Mirati Therapeutics, Inc., Les Laboratoires Servier, SAS, Eli Lilly and Company, Bristol-Myers Squibb Company, Tolero Pharmaceuticals, Inc., Ignyta, Inc., as well as several companies addressing AXL inhibitors, and PARP 1/2 inhibitors and related signaling pathways.

Our competition may also include companies that are or will be developing therapies for the same therapeutic areas that we are targeting, including ovarian cancer, renal cell carcinoma and pancreatic cancer. Many of our potential competitors, alone or with their strategic partners may have substantially greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. These competitors also compete with us in recruiting and retaining qualified scientific and management personal, establishing clinical trial sites and patient registration for clinical trials, and in acquiring technologies complementary to, or necessary for our programs.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain approval from the FDA or other regulatory agencies for their products more rapidly than we may obtain approval for our product candidates, which could result in our competitors establishing a strong market position before our product is able to enter the market. In addition, our ability to compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic products.

License Agreement

In 2012, Aravive Biologics entered into an exclusive license agreement with Leland Stanford Junior University ("Stanford University") for intellectual and tangible property rights relating to biologic inhibitors for therapeutic targeting the receptor tyrosine kinase AXL. The license agreement was amended in 2012, 2015 and 2017 to modify certain of the stated milestones and expand the patent rights granted to Aravive Biologics. The term of the license is the length of the last to expire patent. The license agreement grants Aravive Biologics exclusive, worldwide rights to make, use or sell licensed materials based upon the following patent-related rights:

As consideration for the rights granted in the license agreement, Aravive Biologics is obligated to pay Stanford University yearly license fees and milestone payments, and a royalty based on net sales of products covered by the patent-related rights set forth above. More specifically, Aravive Biologics is obligated to pay Stanford University (i) annual license payments, (ii) milestone payments of up to an aggregate of $1,000,000 upon achievement of clinical and regulatory milestones, and (iii) royalties equal to a percentage (in the low single digits) of net sales of licensed products; provided that the annual license payments made will offset (and be credited against) any royalties due in such license year. In the event of a sublicense to a third party of any rights based on the patents that are solely owned by Stanford University, Aravive Biologics is obligated to pay royalties to Stanford University equal to a percentage of what Aravive Biologics would have been required to pay to Stanford University had it sold the products under sublicense itself. In addition, in such event Aravive Biologics is required to pay to Stanford University a percent of sublicensing income. The license agreement may be terminated by Stanford University upon 30 days written notice if Aravive Biologics breaches its obligations thereunder, including failing to make any milestone or other required payments or to exercise diligence to bring licensed products to market. In the event of a termination, Aravive Biologics will be obligated to pay all amounts that accrued prior to such termination. The license agreement also contains other customary clauses and terms as are common in similar agreements between industry and academia, including the licensee’s agreement to indemnify Stanford University for any liabilities arising out of or related to the licensee’s exercise of its rights under, or breach of, the license agreement, the reservation of the licensor of the right to use the licensed intellectual property rights for its internal, non-commercial purposes, limitations/disclaimers of various warranties.

Cancer Prevention and Research Institute of Texas (CPRIT) Grant

In 2016, Aravive Biologics was approved for a $20.0 million grant from CPRIT for development of AVB-S6. The CPRIT Grant is subject to customary CPRIT funding conditions including a matching funds requirement whereby Aravive Biologics was required to match $0.50 for every $1.00 from CPRIT. Consequently, Aravive Biologics was required to raise $10.0 million in matching funds, and it raised $11.4 million since 2016. The grant award, as is customary for all CPRIT awards, contains a requirement that Aravive Biologics pay CPRIT a tiered royalty on sales of commercial products developed using CPRIT funds equal to a low- to mid-single digit percentage of revenue until such time as CPRIT has been paid an aggregate amount equal to 400% of the grant award proceeds. After 400% of the grant award proceeds has been paid, Aravive Biologics will be obligated to pay CPRIT a royalty of less than one percent for as long as Aravive Biologics maintains government exclusivity. The CPRIT Grant contract terminated on November 30, 2019. After the termination date, we are not permitted to retain any unused grant award proceeds without CPRIT’s approval, but our royalty and other obligations, including our obligation to repay the disbursed grant proceeds under certain circumstances, to maintain certain records and documentation, to notify CPRIT of certain unexpected adverse events and our obligation to use reasonable efforts to ensure that any new or expanded preclinical testing, clinical trials, commercialization or manufacturing related to any aspect of our CPRIT project take place in Texas, survive the termination of the agreement. We have received all $20 million of the grant award proceeds and have expended all of the grant award proceeds by the agreement termination date.

3D Medicines Inc. Agreement

On November 6, 2020, we entered into the 3D Medicines Agreement, whereby we granted 3D Medicines an exclusive license to develop and commercialize products that contain batiraxcept as the sole drug substance, for the diagnosis, treatment or prevention of human oncological diseases, in the Territory.

In August 2021, 3D Medicines received approval from the Center for Drug Evaluation ("CDE") of the China National Medical Products Administration ("NMPA") of the IND submitted by 3D Medicines to participate in our international batiraxcept Phase 3 PROC clinical trial.

Under the terms of the 3D Medicines Agreement, we received from 3D Medicines cash payments of $27 million (inclusive of $15 million in milestone payments) and are eligible to receive from 3D Medicines cash payments of up to an aggregate of $207 million (inclusive of $15 million in milestone payments) in clinical development, regulatory and commercial milestone payments. There can be no guarantee that any such milestones will in fact be met. We are obligated to make certain payments to Stanford University based on certain amounts received from 3D Medicines under the 3D Medicines Agreement pursuant to the existing license agreement by and between us and Stanford.

We will also be entitled to receive tiered royalties ranging from low double digits to mid-teens on sales in the Territory, if any, of products containing batiraxcept. Royalties are payable with respect to each jurisdiction in the Territory until the latest to occur of: (i) the last-to-expire of specified patent rights in such jurisdiction in the Territory; or (ii) ten (10) years after the first commercial sale of a product in such jurisdiction in the Territory. In addition, royalties payable under the Agreement will be subject to reduction on account of generic competition under certain specified conditions, with any such reductions capped at certain percentages of the amounts otherwise payable during the applicable royalty payment period.

The Agreement contemplates that we will enter in ancillary arrangements with 3D Medicines, including a clinical supply agreement and a manufacturing technology transfer agreement.

Intellectual Property

We strive to protect and enhance the proprietary technology, inventions and improvements that are commercially important to our business, including seeking, maintaining, and defending patent rights. We also rely on trade secrets relating to our technology and know-how to develop, strengthen and maintain our proprietary position in the field of targeting the GAS6-AXL pathway for the identification and development of therapeutic candidates for cancer therapy and fibrosis. In addition, we rely on regulatory protection afforded through data exclusivity, market exclusivity and patent term extensions where available. We also utilize trademark protection for our company name and expect to do so for products and/or services as they are marketed.

Our commercial success will 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 therapeutic candidates 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.

Our patent position with respect to the GAS6-AXL program is comprised of nine comprehensive patent portfolios containing composition of matter claims relating to novel GAS6-binding fusion proteins, claims to reagents and diagnostic methods for determining susceptibility or likelihood of a tumor to become invasive and/or metastatic, and claims to the use of our novel fusion proteins for the treatment of various oncological conditions, as well as antiviral and antifibrotic disorders. Our license agreement with Stanford University provides us with exclusive rights to intellectual property ("IP"), that is either solely owned by Stanford (Portfolio I below) or co-owned by Stanford and us (Portfolios II, III, and V below). We also have rights to IP that we solely own (Portfolio IV and VI-X below).

As of February 1, 2023, we have exclusive rights to 50 issued patents (including the 36 validated EP countries for Portfolio I), 2 Hong Kong recorded patents, and one pending patent application that are the subject of the license agreement with Stanford University. The expiration date for those patents/patent applications is 2031. We also have exclusive rights to 58 issued patents (including the 36 validated EP countries for Portfolio III and the 7 validated EP countries for Portfolio V) and 2 pending applications that are jointly owned with Stanford University and that are the subject to the license agreement with Stanford. The expiration dates for those patents/patent applications range from 2033-2035. We have 2 issued patent and 30 pending applications that we solely own. The expiration dates for those patents range from 2035-2042. Additional details on our relevant portfolios is provided below:

In the future, we expect to continue prosecuting broader coverage of certain composition of matter applications. Additionally, we will seek to file new patents related to novel candidates, manufacturing, clinical formulations, dose, and indications, as well as evaluate the acquisition of other innovative IP.

The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most countries in which we file, the patent term is 20 years from the date of filing the non-provisional application. In the United States, a patent’s term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the U.S. Patent and Trademark Office ("USPTO") in granting a patent, or may be shortened if a patent is terminally disclaimed over an earlier-filed patent.

The term of a patent that covers an FDA-approved drug may also be eligible for patent term extension, which permits patent term restoration of a U.S. patent as compensation for the patent term lost during the FDA regulatory review process. The Hatch-Waxman Act permits a patent term extension of up to five years beyond the expiration of the patent. The length of the patent term extension is related to the length of time the drug is under regulatory review. A 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. Moreover, a patent can only be extended once, and thus, if a single patent is applicable to multiple products, it can only be extended based on one product. Similar provisions are available in Europe and other foreign jurisdictions to extend the term of a patent that covers an approved drug. When possible, depending upon the length of clinical trials and other factors involved in the filing of a BLA, we expect to apply for patent term extensions for patents covering its therapeutics candidates and their methods of use.

We may rely, in some circumstances, on trade secrets to protect our technology. However, trade secrets can be difficult to protect. We seek to protect our proprietary technology and processes, in part, by entering into confidentiality agreements with our employees, consultants, scientific advisors and contractors. We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems. While we have confidence in these procedures, agreements or security measures may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our consultants, contractors or collaborators use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

Government Regulation

Federal, state and local government authorities in the United States and in other countries extensively regulate, among other things, the research, development, testing, manufacturing, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of biological and pharmaceutical products such as those we are developing. Our product candidates must be approved by the FDA before they may be legally marketed in the United States and by the appropriate foreign regulatory agencies before they may be legally marketed in foreign countries. The process for obtaining regulatory marketing approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources.

U.S. Drug Approval Process

In the United States, the FDA regulates pharmaceutical and biological products under the Federal Food, Drug and Cosmetic Act, Public Health Service Act (the "PHSA"), and implementing regulations. Products are also subject to other federal, state and local statutes and regulations. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval, may subject an applicant to administrative or judicial sanctions. FDA sanctions could include, among other actions, refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls or withdrawals from the market, product seizures, total or partial suspension of production or distribution injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us. The process required by the FDA before a drug or biological product may be marketed in the United States generally involves the following:

Before testing any biological development candidate in humans, the candidate enters the preclinical testing stage. Preclinical tests, also referred to as nonclinical studies, include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the candidate. The conduct of the preclinical tests must comply with federal regulations and requirements including GLPs. The clinical trial sponsor must submit the results of the preclinical tests, 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. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA raises concerns or questions regarding the proposed clinical trials and places the trial on a clinical hold within that 30-day time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA may also impose clinical holds on a biological product candidate at any time before or during clinical trials due to safety concerns or non-compliance. If the FDA imposes a clinical hold, trials may not recommence without FDA authorization and then only under terms authorized by the FDA. Accordingly, we cannot be sure that submission of an IND will result in the FDA allowing clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate such trials.

Clinical trials involve the administration of the biological product candidate to healthy volunteers or patients under the supervision of qualified investigators, generally physicians not employed by or under the trial sponsor’s control. Clinical trials are conducted under protocols detailing, among other things, the objectives 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. Clinical trials must be conducted and monitored in accordance with the FDA’s regulations composing the GCP requirements, including the requirement that all research subjects provide informed consent. Further, each clinical trial must be reviewed and approved by an independent institutional review board, or IRB, at or servicing each institution at which the clinical trial will be conducted. An IRB is charged with protecting the welfare and rights of trial participants and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the form and content of the informed consent that must be signed by each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. Human clinical trials are typically conducted in three sequential phases; these phases may overlap or be combined:

Post-approval clinical trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These clinical trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication, particularly for long-term safety follow-up.

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 suggest a significant risk for human subjects, or any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The sponsor must submit an IND safety report within 15 calendar days after the sponsor determines that the information qualifies for reporting. The sponsor also must 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 or the sponsor or its data safety monitoring board may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the biological product has been associated with unexpected serious harm to subjects.

Concurrently with clinical trials, companies usually complete additional studies and must also develop additional information about the physical characteristics of the biological product as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the PHSA emphasizes the importance of manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other criteria, the sponsor must develop methods for testing the identity, strength, quality, potency and purity of the final biological product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the biological product candidate does not undergo unacceptable deterioration over its shelf life.

U.S. Review and Approval Processes

After the completion of clinical trials of a biological product, FDA approval of a BLA must be obtained before commercial marketing of the biological product. The BLA must include results of product development, laboratory and animal studies, human trials, information on the manufacture and composition of the product, proposed labeling and other relevant information. The FDA may grant deferrals for submission of data, or full or partial waivers. The testing and approval processes require substantial time and effort and there can be no assurance that the FDA will accept the BLA for filing and, even if filed, that any approval will be granted on a timely basis, if at all.

Under the Prescription Drug User Fee Act ("PDUFA"), as amended, each BLA must be accompanied by a significant user fee. The FDA adjusts the PDUFA user fees on an annual basis. PDUFA also imposes an annual program fee on approved biological products. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a small business. No user fees are assessed on BLAs for products designated as orphan drugs, unless the product also includes a non-orphan indication.

The FDA has a Fast Track program that is intended to expedite or facilitate the process for reviewing new drugs and biological products that meet certain criteria. Specifically, new biological products are eligible for Fast Track designation if they are intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical needs for the condition. Fast Track designation applies to the combination of the product and the specific indication for which it is being studied. For a Fast Track biological product, the FDA may consider review of completed sections of a BLA on a rolling basis provided the sponsor provides, and the FDA accepts, a schedule for the submission of the completed sections of the BLA. Under these circumstances, the sponsor pays any required user fees upon submission of the first section of the BLA. A Fast Track designated drug candidate may also qualify for priority review, under which the FDA reviews the BLA in six months rather than ten months after it is accepted for filing.

Within 60 days following submission of the application, the FDA reviews a BLA submitted to determine if it is substantially complete before the agency accepts it for filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application also is 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 of the BLA. The FDA reviews the BLA to determine, among other things, whether the proposed product is safe, potent, and/or effective for its intended use, and has an acceptable purity profile, 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. The FDA may refer applications for novel biological products or biological products that present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. During the biological product approval process, the FDA also will determine whether a Risk Evaluation and Mitigation Strategy, or REMS, is necessary to assure the safe use of the biological product. If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS. The FDA will not approve a BLA without a REMS, if required.

Before approving a BLA, the FDA 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 adequate to assure consistent production of the product within required specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to assure that the clinical trials were conducted in compliance with IND trial requirements and GCP requirements. To assure cGMP and GCP compliance, an applicant must incur significant expenditure of time, money and effort in the areas of training, record keeping, production, and quality control.

Notwithstanding the submission of relevant data and information, the FDA may ultimately decide that the BLA does not satisfy its regulatory criteria for approval and deny approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the same data. If the agency decides not to approve the BLA in its present form, the FDA will issue a complete response letter that describes all of the specific deficiencies in the BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical trials. Additionally, the complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the BLA, addressing all of the deficiencies identified in the letter, or withdraw the application.

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product.

Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a risk management plan, or otherwise limit the scope of any approval. In addition, the FDA may require post marketing clinical trials, sometimes referred to as Phase 4 clinical trials, designed to further assess a biological product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of approved products that have been commercialized.

In addition, under the Pediatric Research Equity Act, a BLA or supplement to a BLA must contain data to assess the safety and effectiveness of the product 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 grant deferrals for submission of data or full or partial waivers.

Post-Approval Requirements

Any products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, and complying with FDA promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting products for uses or in patient populations that are not described in the product’s approved uses, known as ‘off-label’ use, limitations on industry-sponsored scientific and educational activities, and requirements for promotional activities involving the internet. Although physicians may prescribe legally available products for off-label uses, if the physicians deem to be appropriate in their professional medical judgment, manufacturers may not market or promote such off-label uses.

In addition, quality control and manufacturing procedures must continue to conform to applicable manufacturing requirements after approval to ensure the long-term stability of the product. cGMP regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. Manufacturers and other entities involved in the manufacture and distribution of approved products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved BLA, including, among other things, recall or withdrawal of the product from the market. In addition, changes to the manufacturing process are strictly regulated, and depending on the significance of the change, may require prior FDA approval before being implemented. Other types of changes to the approved product, such as adding new indications and claims, are also subject to further FDA review and approval.

The FDA also may require post-marketing testing, known as Phase 4 testing, and surveillance to monitor the effects of an approved product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our product candidates under development.

Other U.S. Healthcare Laws and Compliance Requirements

In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including but not limited to, the Centers for Medicare and Medicaid Services, or CMS, other divisions of the U.S. Department of Health and Human Services, for instance the Office of Inspector General, the U.S. Department of Justice, or DOJ, and individual U.S. Attorney offices within the DOJ, and state and local governments. For example, sales, marketing and scientific/educational grant programs must comply with the anti-fraud and abuse provisions of the Social Security Act, the false claims laws, the physician payment transparency laws, the privacy and security provisions of HIPAA, as amended by HITECH, and similar state laws, each as amended.

The federal anti-kickback statute prohibits, among other things, any person or entity, from knowingly and willfully offering, paying, soliciting or receiving any remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce or in return for purchasing, leasing, ordering or arranging for the purchase, lease or order of any item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term remuneration has been interpreted broadly to include anything of value. The anti-kickback statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. There are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution. The exceptions and safe harbors are drawn narrowly and practices that involve remuneration that may be alleged to be intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they do not qualify for an exception or safe harbor. Our practices may not in all cases meet all of the criteria for protection under a statutory exception or regulatory safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor, however, does not make the conduct per se illegal under the anti-kickback statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of its facts and circumstances. Violations of this law are punishable by imprisonment, criminal fines, administrative civil money penalties and exclusion from participation in federal healthcare programs.

Additionally, the intent standard under the anti-kickback statute was amended by the Affordable Care Act (“ACA”) to a stricter standard such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the Patient Protection and ACA, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act (“FCA”), as discussed below.

The civil monetary penalties statute imposes penalties against any person or entity that, among other things, is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent.

Although we would not submit claims directly to payors, drug manufacturers can be held liable under the federal civil FCA, which imposes civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities (including manufacturers) for, among other things, knowingly presenting, or causing to be presented to federal programs (including Medicare and Medicaid) claims for items or services, including drugs, that are false or fraudulent, claims for items or services not provided as claimed, or claims for medically unnecessary items or services; making a false statement or record material to payment of a false claim; or avoiding, decreasing or concealing an obligation to pay money to the federal government. Penalties for a FCA violation include three times the actual damages sustained by the government, plus mandatory civil penalties for each separate false claim, the potential for exclusion from participation in federal healthcare programs and, although the federal FCA is a civil statute, conduct that results in a FCA violation may also implicate various federal criminal statutes. The government may deem manufacturers to have “caused” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers or promoting a product off-label. Claims which include items or services resulting from a violation of the federal Anti-Kickback Statute are false or fraudulent claims for purposes of the FCA. Our future marketing and activities relating to the reporting of wholesaler or estimated retail prices for our products, if approved, the reporting of prices used to calculate Medicaid rebate information and other information affecting federal, state and third-party reimbursement for our products, and the sale and marketing of our product and any future product candidates, are subject to scrutiny under this law. Pharmaceutical and other healthcare companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of the product for unapproved, and thus non-reimbursable, uses.

HIPAA created new federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud or to obtain, by means of false or fraudulent pretenses, representations or promises, any money or property owned by, or under the control or custody of, any healthcare benefit program, including private third party payors and knowingly and willfully falsifying, concealing or covering up by trick, scheme or device, 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 violation.

We may be subject to data privacy and security regulations by both the federal government and the states in which we conduct business. HIPAA, as amended by the HITECH Act, and their respective implementing regulations, impose requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to business associates, defined as independent contractors or agents of covered entities, which include health care providers, health plans, and healthcare clearinghouse, that create, receive, or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities and 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 attorney’s fees and costs associated with pursuing federal civil actions. In addition, certain state laws govern the privacy and security of health information in specified circumstances, some of which are more stringent and many of which differ from each other in significant ways, thus complicating compliance efforts. Failure to comply with these laws, where applicable, can result in the imposition of significant civil and criminal penalties.

Additionally, the Federal Physician Payments Sunshine Act under the ACA, and its implementing regulations, require that certain manufacturers of drugs, devices, biological and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, (with certain exceptions), to annually  report to the Centers for Medicare and Medicaid, or CMS, information related to certain payments or other transfers of value made or distributed to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals and to report annually certain ownership and investment interests held by physicians and their immediate family members. Failure to submit timely, accurately, and completely the required information may result in civil monetary penalties. Certain states also mandate implementation of compliance programs, impose restrictions on pharmaceutical manufacturer marketing practices and/or require the tracking and reporting of gifts, compensation and other remuneration to healthcare providers and entities.

In order to distribute products commercially, we must also comply with state laws that require the registration of manufacturers and wholesale distributors of drug and biological products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical and biotechnology companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical and biotechnology companies for use in sales and marketing, and to prohibit certain other sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

If our operations are found to be in violation of any of the federal and state healthcare laws described above or any other governmental regulations that apply to it, we may be subject to penalties, including without limitation, significant civil, criminal and/or administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, private “qui tam” actions brought by individual whistleblowers in the name of the government, or refusal to enter into government contracts, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of operations, any of which could adversely affect our ability to operate our business and our results of operations. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Ensuring business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming and can divert a company’s attention from the business.

Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. In the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend, in part, on the extent to that third-party payors provide coverage, and establish adequate reimbursement levels for such products. In the United States, third-party payors include federal and state healthcare programs, private managed care providers, health insurers and other organizations. The process for determining whether a third-party payor will provide coverage for a product may be separate from the process for setting the price of a product or for establishing the reimbursement rate that such a payor will pay for the product. Third-party payors may limit coverage to specific products on an approved list, also known as a formulary, which might not include all of the FDA-approved products for a particular indication. Third-party payors are increasingly challenging the price, examining the medical necessity and reviewing the cost- effectiveness of medical products, therapies and services, in addition to questioning their safety and efficacy. We may need to conduct expensive pharmaco-economic studies in order to demonstrate the medical necessity and cost-effectiveness of our product candidates, in addition to the costs required to obtain the FDA approvals. Our product candidates may not be considered medically necessary or cost-effective. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage for the product. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on investment in product development.

Different pricing and reimbursement schemes exist in other countries. Some jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. Other countries allow companies to fix their own prices for medicines, but monitor and control company profits. The downward pressure on health care costs has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country.

The marketability of any product candidate for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide adequate coverage and reimbursement. In addition, emphasis on managed care in the United States has increased and we expect the pressure on healthcare pricing will continue to increase. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

U.S. Healthcare Reform

In the United States and some foreign jurisdictions, there have been, and likely will continue to be, a number of legislative and regulatory changes and proposed changes regarding the healthcare system directed at broadening the availability of healthcare, improving the quality of healthcare, and containing or lowering the cost of healthcare.

Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges. It is unclear how these challenges and other efforts to repeal and replace the ACA will impact our business in the future.

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. Additionally, there have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs and reform government program reimbursement methodologies for drugs.

We cannot predict what healthcare reform initiatives may be adopted in the future. Further federal, state and foreign legislative and regulatory developments are likely, and we expect ongoing initiatives to increase pressure on drug pricing. Such reforms could have an adverse effect on anticipated revenues from product candidates and may affect our overall financial condition and ability to develop product candidates.

We anticipate that current and future U.S. legislative healthcare reforms may result in additional downward pressure on the price that we receive for any approved product, if covered, and could seriously harm our business. Any reduction in reimbursement from Medicare and other government programs may result in a similar reduction in payments from private payors.

Foreign Regulation

In order to market any product outside of the United States, we would need to comply with numerous and varying regulatory requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, it would need to obtain the necessary approvals by the comparable foreign regulatory authorities before it can commence clinical trials or marketing of the product in foreign countries and jurisdictions. Although many of the issues discussed above with respect to the United States apply similarly in the context of the European Union, the approval process varies between countries and jurisdictions and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries and jurisdictions might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others.

European Data Collection

The collection and use of personal health data in the European Economic Area (EEA) is governed by the General Data Protection Regulation 2016/679 ("GDPR"), which became effective May 25, 2018. The GDPR applies to any company established in the EEA and to companies established outside the EEA that process personal data in connection with the offering of goods or services to data subjects in the EU or the monitoring of the behavior of data subjects in the EU. The GDPR enhances data protection obligations for data controllers of personal data (including stringent requirements relating to the consent of data subjects, expanded disclosures about how personal data is used, requirements to conduct privacy impact assessments for “high risk” processing, limitations on retention of personal data, mandatory data breach notification and “privacy by design” requirements) and creates direct obligations on service providers acting as data processors. The GDPR also imposes strict rules on the transfer of personal data outside of the EEA to countries that do not ensure an adequate level of protection, like the U.S. Failure to comply with the requirements of the GDPR and the related national data protection laws of the EEA Member States may result in fines up to 20 million Euros or 4% of a company’s global annual revenues for the preceding financial year, whichever is higher. Moreover, the GDPR grants data subjects the right to claim material and non-material damages resulting from infringement of the GDPR. Given the breadth and depth of changes in data protection obligations, maintaining compliance with the GDPR, will require significant time, resources and expense, and we may be required to put in place additional mechanisms ensuring compliance with the new data protection rules. This may be onerous and adversely affect our business, financial condition, results of operations and prospects.

Human Capital

We believe that our success depends upon our ability to attract, develop and retain key personnel. Our management and scientific teams possess considerable experience in drug discovery, research, manufacturing, clinical development and regulatory matters and we believe that we benefit from this experience and industry knowledge. Our research team includes M.D., M.S., and Ph.D.-level scientists with expertise in cancer biology. As of December 31, 2022, we had 23 full-time employees, of which 15 were part of our research team and 8 were part of our general and administrative team. Of the management team, 80% are women or minorities. We have no collective bargaining agreements with our employees and have not experienced any work stoppages. We consider our relations with our employees to be good. Although, management continually seeks to add additional talent to its work force, management believes that it has sufficient human capital to operate its business successfully.

Competitive Pay and Benefits

Our compensation programs are designed to align the compensation of our employees with our performance and to provide the proper incentives to attract, retain and motivate employees to achieve superior results. The structure of our compensation programs balances incentive earnings for both short-term and long-term performance. Specifically:

Health and Safety

The health and safety of our employees is our highest priority, and this is consistent with our operating philosophy. Accordingly, with the global spread of the ongoing novel COVID-19 pandemic, we have implemented plans designed to address and mitigate the impact of the COVID-19 pandemic on the safety of our employees and our business, which include:

Core Values and Culture

Fostering and maintaining a strong, healthy culture is a key strategic focus. Our core values reflect who we are and the way our employees interact with one another, our customers, partners and shareholders. Our core values include: treating one another with respect, considering the needs of others and providing solutions to meet their needs, being constantly working to improve and willing to try new approaches, making decisions with the long-term view in mind, and acting as a team by listening to one another and working across teams toward a common goal. We collaborate to achieve results and focus on success for our patients and shareholders.

Corporate Information

We were incorporated under the laws of the State of Delaware in December 2008 under the name Versartis, Inc. and completed our initial public offering in March 2014. Aravive Biologics was incorporated under the laws of the State of Delaware in April 2007, originally under the name of Hypoximed, Inc, which name was changed to Ruga Corporation in July 2009 and changed to Aravive Biologics, Inc. in October 2016. On October 12, 2018, we, then known as Versartis, Inc. and Aravive Biologics, completed a merger and reorganization (the "Merger"), pursuant to which Aravive Biologics survived as our wholly owned subsidiary.  In connection with the completion of the Merger, on October 15, 2018, we changed our name from Versartis, Inc. to “Aravive, Inc.” and on October 16, 2018, we effected a reverse split of our common stock at a ratio of 1-for-6 (the "Reverse Split").

Item 1A. Risk Factors.

Investing in our common stock involves a high degree of risk. You should consider carefully the following risks, together with all the other information in this Annual Report on Form 10-K, including the section titled “Cautionary Note Regarding Forward-Looking Statements,” and Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operation” and our consolidated financial statements and the accompanying notes included elsewhere in this Annual Report on Form 10-K. The risks described below are not the only ones we face. Any of the following risks could materially and adversely affect our business. If any of the following risks actually materializes, our operating results, financial condition and liquidity could be materially adversely affected. As a result, the trading price of our common stock could decline and you could lose part or all of your investment. Our business, financial condition and results of operations could also be harmed by risks and uncertainties not currently known to us or that we currently do not believe are material.

Risks Related to Our Financial Position And Capital Requirements.

We have a limited operating history and have incurred significant losses since our inception, and we anticipate that we will continue to incur substantial and increasing losses for the foreseeable future. We have only one product candidate, batiraxcept, and no commercial sales, which, together with our limited operating history, makes it difficult to evaluate our business and assess our future viability.

We are a clinical-stage biopharmaceutical company with a limited operating history. We have never generated any product revenue and do not have any products approved for sale.

Our operations to date have been primarily focused on developing our only product candidate, batiraxcept. We have not yet successfully obtained marketing approval, manufactured batiraxcept product at commercial scale, or conducted sales and marketing activities that will be necessary to successfully commercialize batiraxcept. Consequently, predictions about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and commercializing product candidates.

Even if we receive regulatory approval for the sale of any of our product candidates, we do not know when we will begin to generate revenue, if at all. Our ability to generate revenue depends on a number of factors, including our ability to:

Because of the numerous risks and uncertainties associated with development and manufacturing, we are unable to predict if we will generate revenue. If we cannot successfully execute on any of the factors listed above, our business may not succeed, we may never generate revenue and your investment will be adversely affected.

We have incurred significant losses since inception and expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability.

We have incurred significant operating losses in each year since our inception and expect to incur substantial and increasing losses for the foreseeable future. As of December 31, 2022, we had an accumulated deficit of approximately $616.1 million.

To date, we have financed our operations primarily through private placements of our equity securities, debt financing, CPRIT grant proceeds, at-the-market offerings of our common stock, public offerings of our common stock as well as upfront and milestone payments received from license agreements. We have devoted substantially all of our efforts to research and development, including clinical studies, but have not completed development of any product candidate. We anticipate that our expenses will increase to the extent we:

To be profitable in the future, we must succeed in developing and eventually commercializing batiraxcept as well as other products with significant market potential. This will require us to be successful in a range of activities, including advancing batiraxcept and any future product candidates, completing clinical studies of these product candidates, obtaining regulatory approval for these product candidates and manufacturing, marketing and selling those products for which we may obtain regulatory approval.  We may not succeed in these activities and may never generate revenue that is sufficient to be profitable in the future. Even if we are profitable, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to achieve sustained profitability would depress the value of our company and could impair our ability to raise capital, expand our business, diversify our product candidates, market our product candidates, if approved, or continue our operations.

We expect our research and development expenses to increase significantly as our product candidates advance in clinical development. Because of numerous risks and uncertainties involved in our business, the timing or amount of increased development expenses cannot be accurately predicted and, our expenses could increase beyond expectations if we are required by the FDA, or comparable non-U.S. regulatory authorities, to perform studies or clinical trials in addition to those we currently anticipate. Even if our product candidate, batiraxcept, is approved for commercial sale, we anticipate incurring significant costs associated with the commercial launch of and the related commercial-scale manufacturing requirements for batiraxcept. As a result, we expect to continue to incur significant and increasing operating losses and negative cash flows for the foreseeable future. Because of the numerous risks and uncertainties associated with biopharmaceutical product development and commercialization, we are unable to accurately predict the timing or amount of future expenses or when, or if, we will be able to achieve or maintain profitability. These losses have had and will continue to have an adverse effect on our financial position and working capital.

There is uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt about our ability to continue as a going concern.

Our consolidated audited financial statements as of and for the year ended December 31, 2022 have been prepared under the assumption that we will continue as a going concern for the next twelve months. Our management concluded that our recurring losses from operations and the fact that we have not generated significant revenue or positive cash flows from operations raise substantial doubt about our ability to continue as a going concern for the next twelve months after issuance of our financial statements. Our auditors also included an explanatory paragraph in its report on our financial statements as of and for the year ended December 31, 2022 with respect to this uncertainty.  Our ability to continue as a going concern is dependent upon our ability to obtain additional equity or debt financing, attain further operating efficiencies, reduce expenditures, and, ultimately, to generate revenue. Since inception, we have incurred net losses and negative cash flows from operations. At December 31, 2022, we had an accumulated deficit of $616.1 million and working capital of $35.9 million. We expect to continue to incur losses from expenses related to the development of batiraxcept and related administrative activities for the foreseeable future. As of December 31, 2022, we had a cash and cash equivalents balance of approximately $53.7 million consisting of cash and investments in highly liquid U.S. money market funds. We believe that our current cash and cash equivalents will be sufficient to fund our current planned operations into the fourth quarter of 2023 but that we will need to seek additional capital to fulfill our operating and capital requirement for the next 12 months to advance our clinical development program to later stages of development and commercialize our clinical product candidate. Although management has been successful in raising capital in the past, there can be no assurance that we will be successful or that any needed financing will be available in the future at terms acceptable to the Company. As such, the Company cannot conclude that such plans will be effectively implemented within one year after the date that the financial statements included in this Annual Report on Form 10-K are filed with the SEC and there is uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt about our ability to continue as a going concern.

We will need additional funds to support our operations, and such funding may not be available to us on acceptable terms, or at all, which would force us to delay, reduce or suspend our research and development programs and other operations or commercialization efforts.

The completion of the development and the potential commercialization of batiraxcept and any future product candidates, should they receive approval, will require substantial funds. In addition, we expect our manufacturing costs to significantly increase this year as we prepare for submission of a BLA and potential commercialization. As of December 31, 2022, we had approximately $53.7 million in cash and cash equivalents. We believe that our existing cash and cash equivalents will be sufficient to fund our current planned operations into the fourth quarter of 2023 based on our existing business plan; however, our existing cash and cash equivalents will not be sufficient to enable us to complete the clinical development and commercialization of batiraxcept. Our future financing requirements will depend on many factors, some of which are beyond our control, including the following:

We do not have any material committed external source of funds or other support for our development efforts. Although we have entered into an at-the-market facility with Piper Sandler & Co. (“Piper Sandler”), and Cantor Fitzgerald & Co. (“Cantor Fitzgerald”), as sales agents, there can be no assurance that we will meet all of the conditions necessary to continue to use such facility or that we can generate sufficient proceeds from the sale of securities pursuant to such facility to support our operations. Until we can generate a sufficient amount of product revenue to finance our cash requirements, which we may never do, we expect to finance future cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing and distribution arrangements. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants that may impact our ability to conduct our business and may be negatively impacted by inflation. Additional financing may not be available to us when we need it or it may not be available on favorable terms. In addition, certain SEC limitations due to our non-affiliate float being less than $75 million and certain Nasdaq Stock Market Global limitations with respect to fundraising, including limitations on the use of our shelf registration statement, may make it more difficult to raise additional funds. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of, or suspend one or more of our clinical studies or research and development programs or our commercialization efforts.

Raising additional funds by issuing securities may cause dilution to existing stockholders, and raising funds through lending and licensing arrangements may restrict our operations or require it to relinquish proprietary rights.

We expect that significant additional capital will be needed in the future to continue our planned operations and commercialize batiraxcept. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, strategic alliances and license and development agreements in connection with any collaborations. We do not currently have any committed external source of funds. To the extent that we raise additional capital by issuing equity securities, existing stockholders’ ownership may experience substantial dilution, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of a common stockholder. In addition, the exercise of outstanding warrants and options will also cause dilution. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, declaring dividends, creating liens, redeeming its stock or making investments.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, or through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties on acceptable terms, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise develop and market.

Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or our guidance.

Our quarterly and annual operating results may fluctuate significantly in the future, which makes it difficult for us to predict our future operating results. From time to time, we may enter into collaboration agreements with other companies that include development funding and significant upfront and milestone payments and/or royalties, which may become an important source of our revenue. Accordingly, our revenue may depend on development funding and the achievement of development and clinical milestones under any potential future collaboration and license agreements and sales of our products, if approved. These upfront and milestone payments may vary significantly from period to period and any such variance could cause a significant fluctuation in our operating results from one period to the next. In addition, our manufacturing and clinical trial expenses, which are anticipated to be significant, may fluctuate significantly quarter to quarter based upon whether or not we are engaged in clinical trials or manufacturing our product candidate, batiraxcept, and timing of our process development work.  Furthermore, we measure compensation cost for stock-based awards made to employees at the grant date of the award, based on the fair value of the award as determined by our board of directors, and recognize the cost as an expense over the employee’s requisite service period. As the variables that we use as a basis for valuing these awards change over time, our underlying stock price and stock price volatility, the magnitude of the expense that we must recognize may vary significantly. Furthermore, our operating results may fluctuate due to a variety of other factors, many of which are outside of our control and may be difficult to predict, including the following:

The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Investors should not rely on our past results as an indication of our future performance. This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated revenue and/or earnings guidance we may provide.

Risks Related To Our Business

Changes in general economic conditions, geopolitical conditions, domestic and foreign trade policies, monetary policies and other factors beyond our control may adversely impact our business and operating results.

Our operations and performance depend on global, regional and U.S. economic and geopolitical conditions. General worldwide economic conditions have experienced significant instability in recent years including the recent global economic uncertainty and financial market conditions. Russia’s invasion and military attacks on Ukraine have triggered significant sanctions from U.S. and European leaders and financial markets around the world experienced volatility following the invasion of Ukraine by Russia in February 2022. Resulting changes in U.S. trade policy could trigger retaliatory actions by Russia, its allies and other affected countries, including China, resulting in a “trade war.” Furthermore, if other countries, including the U.S., become further involved in the conflict, we could face significant adverse effects to our business and financial condition.

As we advance our clinical programs, we are in close contact with our clinical research organizations ("CROs") and clinical sites and are continually assessing the impact of COVID-19 on our planned trials and current timelines and costs as well as the impact of the invasion and military attacks on Ukraine. The uncertain financial markets, disruptions in supply chains, mobility restraints, and changing priorities as well as volatile asset values could impact our business in the future. The COVID-19 outbreak and government measures taken in response to the pandemic have also had a significant impact, both direct and indirect, on businesses and commerce, as worker shortages have occurred; supply chains have been disrupted; facilities and production have been suspended; and demand for certain goods and services, such as medical services and supplies, have spiked, while demand for other goods and services, such as travel, have fallen. The future progression of the pandemic and its effects on our business and operations are uncertain. We may face difficulties recruiting or retaining patients in our ongoing and planned clinical trials if patients are affected by the virus or are fearful of traveling to our clinical trial sites because of the outbreak or the military situation in Ukraine expands into other countries where we have or plan to conduct clinical trials. Any such disruptions or delays would, and any such increased clinical program expenses could, adversely affect our business, financial condition, results of operations and growth prospects. We and our third-party contract manufacturers, contract research organizations, and clinical sites may also face disruptions in procuring items that are essential to our research and development activities, including, for example, medical and laboratory supplies used in our clinical trials or preclinical studies, in each case, that are sourced from abroad or for which there are shortages because of ongoing efforts to address the outbreak. Further, although we have not experienced any material adverse effects on our business due to increasing inflation, it has raised operating costs for many businesses and, in the future, could impact demand or pricing manufacturing of our drug candidates or services providers, foreign exchange rates or employee wages. Inflation rates, particularly in the United States and United Kingdom, have increased recently to levels not seen in years, and increased inflation may result in increases in our operating costs (including our labor costs), reduced liquidity and limits on our ability to access credit or otherwise raise capital. In addition, the Federal Reserve has raised, and may again raise, interest rates in response to concerns about inflation, which coupled with reduced government spending and volatility in financial markets may have the effect of further increasing economic uncertainty and heightening these risks.

Actual events involving reduced or limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank, was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation as receiver. Although we did not have any cash or cash equivalent balances on deposit with Silicon Valley Bank, uncertainty and liquidity concerns in the broader financial services industry remain and the failure of Silicon Valley Bank and its potential near- and long-term effects on the biotechnology industry and its participants such as our vendors, suppliers, and investors, may also adversely affect our operations and stock price.

We are actively monitoring the effects these disruptions and increasing inflation could have on our operations.

These conditions make it extremely difficult for us to accurately forecast and plan future business activities.

The above factors, including a number of other economic and geopolitical factors both in the U.S. and abroad, could ultimately have material adverse effects on our business, financial condition, results of operations or cash flows, including the following:

In addition, the outbreak of a pandemic could disrupt our operations due to absenteeism by infected or ill members of management or other employees, or absenteeism by members of management and other employees who elect not to come to work due to the illness affecting others in our office or laboratory facilities, or due to quarantines. Pandemics could also impact members of our Board of Directors resulting in absenteeism from meetings of the directors or committees of directors, and making it more difficult to convene the quorums of the full Board of Directors or its committees needed to conduct meetings for the management of our affairs.

Business disruptions could seriously harm our future revenue and financial condition and increase costs and expenses.

Our operations and those of our third-party suppliers and collaborators, including our manufacturer, could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes or other extreme weather conditions, medical epidemics, labor disputes, war or other business interruptions. Any interruption could seriously harm our ability to timely proceed with any clinical programs or to supply product candidates for use in our clinical programs or during commercialization. For example, the current COVID-19 pandemic has, at points, caused an interruption in our clinical trial activities. Additionally, supply chains disruptions impact and may continue to impact our research activities. Moreover, the invasion of Ukraine and the retaliatory measures that have been taken, or could be taken in the future, by the United States, NATO, and other countries have created global security concerns that could result in a regional conflict and otherwise have a lasting impact on regional and global economies, any or all of which could disrupt our supply chain and adversely affect our ability to conduct ongoing and future clinical trials of our product candidates. This could negatively impact the anticipated timing and completion of our clinical trials and/or analyses of clinical results. In addition, if any sanctions were to be imposed on China that effect the export of our clinical trial materials, our ability to complete current and future clinical trials could be adversely impacted.

Reliance on government funding for our programs may impose requirements that limit our ability to take certain actions, and subject us to potential financial penalties, which could materially and adversely affect our business, financial condition and results of operations.

A significant portion of our funding has been through a grant Aravive Biologics received from CPRIT. The CPRIT Grant (as described below) includes provisions that reflect the government’s substantial rights and remedies, many of which are not typically found in commercial contracts, including powers of the government to potentially require repayment of all or a portion of the grant award proceeds, in certain cases with interest, in the event we violate certain covenants pertaining to various matters that include any potential relocation outside of the State of Texas. Although our contract with CPRIT terminated November 30, 2019, our royalty and other obligations, including our obligation to repay the disbursed grant proceeds under certain circumstances, to maintain certain records and documentation, to notify CPRIT of certain unexpected adverse events  and our obligation to use reasonable efforts to ensure that any new or expanded preclinical testing, clinical trials, commercialization or manufacturing related to any aspect to our CPRIT project  take place in Texas, survive the termination of the agreement. We have received the full $20.0 million of the grant proceeds and have expended all of the grant award proceeds by the agreement termination date.

Our award from CPRIT requires us to pay CPRIT a portion of our revenues from sales of certain products by us, or received from our licensees or sublicensees, at tiered percentages of revenue in the low- to mid-single digits until the aggregate amount of such payments equals 400% of the grant award proceeds, and thereafter at a rate of less than one percent for as long as we maintain government exclusivity, subject to our right, under certain circumstances, to make a one-time payment in a specified amount to CPRIT to terminate such payment obligations.

In order to meet the requirements that any new or expanded preclinical testing, clinical trials, commercialization or manufacturing related to any aspect of our CPRIT project take place in Texas, we will need to hire additional qualified personnel and vendors with expertise in preclinical testing, clinical research and testing, government regulation, formulation and manufacturing, sales and marketing and accounting and financing located in Texas. We will compete for qualified individuals, vendors, clinical trial sites, manufacturers with numerous biopharmaceutical companies, universities and other research institutions. Competition for such individuals is intense, and there can be no assurance that the search for such personnel will be successful, especially in light of the territorial restrictions imposed by CPRIT.

If we fail to maintain compliance with any such requirements that may apply to us now or in the future, we may be subject to potential liability and to termination of our contracts, including potentially the CPRIT Grant, which could result in significant expense to us.

We rely on licenses to use various technologies that are material to our business and if the agreements underlying the licenses were to be terminated or if other rights that may be necessary for commercializing our intended products cannot be obtained, it would halt our ability to market our products and technology, as well as have an immediate material adverse effect on our business, operating results and financial condition.

Our prospects are significantly dependent upon our license with Stanford University (the "Stanford License"). The Stanford License grants us exclusive, worldwide rights to certain existing patents and related intellectual property that cover batiraxcept, the development candidate selected from the AVB-S6 family of proteins. If we breach the terms of the Stanford License, including any failure to make minimum royalty payments required thereunder or failure to reach certain developmental milestones and by certain deadlines or other factors, including but not limited to, the failure to comply with material terms of the Stanford License, the licensor has the right to terminate the license. If we were to lose or otherwise be unable to maintain the license on acceptable terms, or find that it is necessary or appropriate to secure new licenses from other third parties, we would not be able to market our products and technology, which would likely require us to cease our current operations which would have an immediate material adverse effect on our business, operating results and financial condition.

If we fail to comply with our obligations in our intellectual property licenses, we could lose license rights that are important to our business.

In addition to the Stanford License, we are a party to intellectual property license agreements with third parties, and we expect to enter into additional license agreements in the future. Our existing license agreements impose, and we expect that our future license agreements will impose, various diligence, milestone payment, royalty, insurance and other obligations on us. If we fail to comply with these obligations, our licensors may have the right to terminate these agreements, in which event we may not be able to develop and market any product that is covered by these agreements. The occurrence of such events could materially harm our business and financial condition.

The risks described elsewhere pertaining to our intellectual property rights also apply to the intellectual property rights that we license, and any failure by us or our licensors to obtain, maintain, defend and enforce these rights could have a material adverse effect on our business. In some cases, we do not have control over the prosecution, maintenance or enforcement of the patents that we license, and may not have sufficient ability to provide input into the patent prosecution, maintenance and defense process with respect to such patents, and our licensors may fail to take the steps that we believe are necessary or desirable in order to obtain, maintain, defend and enforce the licensed patents. We are responsible for preparing, filing, and prosecuting broad patent claims (including any interference or reexamination actions) for Stanford University’s benefit and for maintaining all licensed patents.

We expect to depend on collaborations with third parties for the development and commercialization of some of our products and product candidates outside of the United States. Our prospects with respect to those products and product candidates will depend in part on the success of those collaborations.

Although we are commercializing batiraxcept ourselves in the United States, we intend to seek to commercialize batiraxcept outside the United States through collaboration arrangements. For instance, we entered into the 3D Medicines Agreement under which we granted 3D Medicines an exclusive sublicense to develop and commercialize batiraxcept, in the Territory.

We may not be able to derive revenue from research and development fees, license fees, milestone payments and royalties under any collaborative arrangement into which we enter. Our ability to generate revenues from these arrangements will depend on our collaborators’ abilities to successfully perform the functions assigned to them in these arrangements, including obtaining regulatory approval in the sublicensed territory, which may not be obtainable even if we obtain regulatory approval to market products in the United States. In addition, our collaborators may have the right to abandon research or development projects and terminate applicable agreements, including funding obligations, prior to or upon the expiration of the agreed upon terms. As a result, we can expect to relinquish some or all of the control over the future success of a product or product candidate that we license to a third party.

Collaborations involving our products and product candidates, such as our license arrangement with 3D Medicines, may pose a number of risks, including the following:

Collaboration agreements may not lead to development or commercialization of products or product candidates in the most efficient manner or at all.

In addition, any negative results from clinical trials conducted by any third-party collaborator, including 3D Medicines, will negatively impact our commercialization efforts despite the fact that we will not have conducted those trials.

We rely extensively on our information technology systems which are vulnerable to damage and interruption.

We rely on our information technology systems and infrastructure to process transactions, summarize results and manage our business, including maintaining client and supplier information. Additionally, we utilize third parties, including cloud providers, to store, transfer and process data. Our information technology systems, as well as the systems of our suppliers and other partners, whose systems we do not control, are vulnerable to outages and an increasing risk of continually evolving deliberate intrusions to gain access to company sensitive information. Likewise, data security incidents and breaches by employees and others with or without permitted access to our systems pose a risk that sensitive data may be exposed to unauthorized persons or to the public. A cyber-attack or other significant disruption involving our information technology systems, or those of our vendors, suppliers and other partners, could also result in disruptions in critical systems, corruption or loss of data and theft of data, funds or intellectual property.  We may be unable to prevent outages or security breaches in our systems. Loss of preclinical or clinical trial data could result in delays in regulatory approval efforts and increase costs to recover or reproduce data. We remain potentially vulnerable to additional known or yet unknown threats as, in some instances, we, our suppliers and our other partners may be unaware of an incident or its magnitude and effects. We also face the risk that we expose our vendors or partners to cybersecurity attacks. Any or all of the foregoing could adversely affect our results of operations and our business reputation.

Any failure to maintain the security of information relating to our customers, employees and suppliers, whether as a result of cybersecurity attacks or otherwise, could expose us to litigation, government enforcement actions and costly response measures, and could disrupt our operations and harm our reputation. 

In connection with the sales and marketing of our products and services, we may from time to time transmit confidential information. We also have access to, collect or maintain private or confidential information regarding our clinical trials and the patients enrolled therein, employees, and suppliers, as well as our business. Cyberattacks are rapidly evolving and becoming increasingly sophisticated. It is possible that computer hackers and others might compromise our security measures, or security measures of those parties that we do business with now or in the future, and obtain the personal information of patients in our clinical trials, vendors, employees and suppliers or our business information. A security breach of any kind, including physical or electronic break-ins, computer viruses and attacks by hackers, employees or others, could expose us to risks of data loss, litigation, government enforcement actions, regulatory penalties and costly response measures, and could seriously disrupt our operations. Any resulting negative publicity could significantly harm our reputation, which could cause us to lose market share and have an adverse effect on our results of operations.

We may face particular data protection, data security and privacy risks in connection with privacy regulations.

In the United States we are subject to several laws that protect the privacy of protected health information as well as data breach notification laws, the violation of which can result in penalties, criminal and civil penalties. Outside of the United States, the laws, regulations and standards in many jurisdictions apply broadly to the collection, use, and other processing of personal information. For example, in the European Union, the collection and use of personal data are governed by the provisions of the General Data Protection Regulation (the “GDPR”). The GDPR, together with national legislation, regulations and guidelines of the European Union. member states governing the processing of personal data, impose strict obligations on entities, including but not limited to: (i) accountability and transparency requirements, and enhanced requirements for obtaining valid consent from data subjects; (ii) obligations to consider data protection as any new products or services are developed and to limit the amount of personal data processed; (iii) obligations to comply with the data protection rights of data subjects; and (iv) obligations to report certain personal data breaches to governmental authorities and individuals. Data protection authorities from the different E.U. member states and other European countries may enforce the GDPR and national data protection laws differently and introduce additional national regulations and guidelines, which adds to the complexity of processing European personal data. Failure to comply with the requirements of the GDPR and national data protection laws may result in significant monetary fines and other administrative penalties (the GDPR authorizes fines for certain violations of up to 4% of global annual revenue or €20 million, whichever is greater) as well as civil liability claims from individuals whose personal data was processed. Additionally, expenses associated with compliance could reduce our operating margins.

The GDPR also prohibits the transfer of personal data from the E.U. to countries outside of the E.U. unless made to a country deemed by the European Commission to provide adequate protection for personal data or accomplished by means of an approved data transfer mechanism (e.g., standard contractual clauses). Data protection authority guidance and enforcement actions that restrict companies’ ability to transfer data may increase risks relating to data transfers or make it more difficult or impossible to transfer E.U. personal data to the U.S.

We currently have only one product candidate, batiraxcept, in clinical development and are dependent on the success of batiraxcept, which requires additional clinical testing before seeking regulatory approval. If batiraxcept does not successfully complete clinical trials and receive regulatory approval or is not successfully commercialized, our business will be harmed.

We are currently developing one clinical product candidate, batiraxcept, as a potential treatment for several types of cancer. Batiraxcept is currently being tested in clinical trials, and, to date, we have not had any product candidate approved for commercial sale. It is possible that we may never be able to develop a marketable product candidate. Our main focus is the development of batiraxcept, for the treatment of platinum-resistant recurrent ovarian cancer, ccRCC and pancreatic cancer. If our Phase 3 trial of batiraxcept for PROC is successful, we expect to submit a BLA to the FDA at the end of 2023.  The FDA may refuse to file a BLA or issue a complete response letter rather than approval, including for reasons that it disagrees with our interpretation of the data or that it finds our single pivotal trial insufficient evidence of clinical efficacy.  FDA may ask us to conduct another Phase 3 trial.

We expect that a substantial portion of our efforts and expenditures over the next few years will be devoted to batiraxcept. Accordingly, our business currently depends heavily on the successful development, regulatory approval and commercialization of batiraxcept, which may not receive regulatory approval or be successfully commercialized even if regulatory approval is received. The research, testing, manufacturing, labeling, approval, sale, marketing and distribution of product candidates are and will remain subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries that each have differing regulations. We are not permitted to market any product in the United States unless and until we receive approval of a BLA, from the FDA, or in any foreign countries unless and until we receive the requisite approval from regulatory authorities in such countries. We have never submitted a BLA to the FDA or comparable applications to other regulatory authorities and expect to submit one at the end of 2023, if our ongoing Phase 3 PROC trial is successful. Obtaining approval of a BLA is an extensive, lengthy, expensive and inherently uncertain process, and the FDA may delay, limit or deny approval of a product for many reasons.

Our success depends largely upon our ability to advance our clinical product candidate, batiraxcept, which is in early stages of development, through the various stages of drug development. If we are unable to successfully advance or develop batiraxcept, our business will be materially harmed.

Our clinical product candidate, batiraxcept, is in early stages of clinical development, and its commercial viability remains subject to the successful outcome of future preclinical studies, clinical trials, manufacturing processes, regulatory approvals and the risks generally inherent in the development of pharmaceutical product candidates. Failure to advance the development of batiraxcept may have a material adverse effect on our business. The long-term success of our business ultimately depends upon our ability to advance the development of batiraxcept through clinical trials, appropriately formulate and consistently manufacture it in accordance with strict specifications and regulations, obtain approval for sale by the FDA or similar regulatory authorities in other countries, and ultimately successfully commercialize it directly or with a strategic partner or licensee. We cannot assure investors that the results of our ongoing or future research, preclinical studies or clinical trials will support or justify the continued development of batiraxcept or that we will ultimately receive approval from the FDA, or similar regulatory authorities in other countries, to advance the development of batiraxcept.

Batiraxcept must satisfy rigorous regulatory standards of safety, efficacy and manufacturing before we can advance or complete its development and before it can be approved for sale by the FDA or similar regulatory authorities in other countries. To satisfy these standards, we must engage in expensive and lengthy studies and clinical trials, develop acceptable and cost-effective manufacturing processes, and obtain regulatory approval of batiraxcept. Despite these efforts, batiraxcept may not:

Even if we demonstrate favorable results in preclinical studies and early-stage clinical trials, we cannot assure you that the results of late-stage clinical trials will be sufficient to support the continued development of batiraxcept. Many, if not most, companies in the pharmaceutical and biopharmaceutical industries have experienced significant delays, setbacks and failures in all stages of development, including late-stage clinical trials, even after achieving promising results in preclinical testing or early-stage clinical trials. Accordingly, results from completed preclinical studies and early-stage clinical trials of our batiraxcept may not be predictive of the results we may obtain in future late-stage trials, especially in light of the fact that the results from our clinical trials to date have been from a small number of patients and may not be replicated with a larger number of patients. Furthermore, even if the data collected from preclinical studies and clinical trials involving any of our clinical product candidates demonstrate a satisfactory safety, tolerability and efficacy profile, such results may not be sufficient to obtain regulatory approval from the FDA in the United States, or other similar regulatory agencies in other jurisdictions, which is required to market and sell the product.

Clinical trials are risky, lengthy and expensive. We incur substantial expense for, and devote significant time and resources to, preclinical testing and clinical trials, yet cannot be certain that these tests and trials will demonstrate that a product candidate is effective and well-tolerated, or will ever support its approval and commercial sale. For example, clinical trials require adequate supplies of clinical trial material and sufficient patient enrollment to power the trial. Delays in patient enrollment can result in increased costs and longer development times. Even if we, or a licensee or collaborator, if applicable, successfully complete clinical trials for batiraxcept, we or they might not file the required regulatory submissions in a timely manner and may not receive marketing approval for batiraxcept. We cannot assure you that batiraxcept will successfully progress further through the drug development process, or ultimately will result in an approved and commercially viable product.

We have limited experience conducting clinical trials.

We are an early-stage clinical stage company, and our success is dependent upon our ability to obtain regulatory approval for and commercialization of batiraxcept, and we have not demonstrated an ability to perform the functions necessary for the approval or successful commercialization of any product candidate. The successful commercialization of any product candidate may require us to perform a variety of functions, including:

We have limited experience conducting and enrolling subjects in clinical trials. While certain members of our management and staff have significant experience in conducting clinical trials, to date, we have only limited experience conducting clinical trials. In part because of this lack of experience, we cannot guarantee that planned clinical trials will be completed on time, if at all, or that we will not require changes to our trial designs. Large-scale trials require significant additional financial and management resources, monitoring and oversight, and reliance on third-party clinical investigators, consultants or contract research organizations, or CROs. Relying on third-party clinical investigators, CROs and manufacturers, which are all also subject to governmental oversight and regulations, may also cause us to encounter delays that are outside of our control.

If the actual or perceived therapeutic benefits, or the safety or tolerability profile of our clinical product candidate, batiraxcept, is not equal to or superior to other competing treatments approved for sale or in clinical development, we may terminate the development of batiraxcept at any time, and our business prospects and potential profitability could be harmed.

We are aware of a number of companies marketing or developing product candidates for the treatment of patients with cancer and fibrosis that are either approved for sale or further advanced in clinical development than ours, such that their time to approval and commercialization may be shorter than that for batiraxcept.

There are currently no FDA approved biological drugs that target the GAS6/AXL pathway. However, if ever approved as a treatment for cancer, batiraxcept would indirectly compete with drugs approved to treat various types of cancer, such as those that regulate T-cell proliferation, including nivolumab, pembrolizumab, atezolizumab and other small molecule chemically manufactured drugs that target this pathway or other classes of drugs that are used for the clinical indications that ours is currently pursuing in clinic.

If at any time we believe that batiraxcept may not provide meaningful or differentiated therapeutic benefits, perceived or real, equal to or better than its competitor’s products or product candidates, or we believe that it may not have as favorable a safety or tolerability profile as potentially competitive compounds, we may delay or terminate its development. We cannot provide any assurance that the future development of batiraxcept will demonstrate any meaningful therapeutic benefits over potentially competitive compounds currently approved for sale or in development, or an acceptable safety or tolerability profile sufficient to justify its continued development.

For the Phase 3 clinical trial in patients with platinum-resistant recurrent ovarian cancer and for the Phase 1b/2 clinical trials in patients with ccRCC or pancreatic adenocarcinoma we are administering, or plan to administer, our clinical product candidate, batiraxcept, in combination with approved standard of care drugs. Any problems obtaining the standard of care drugs could result in a delay or interruption in our clinical trials.

For each of our ongoing clinical trials, we are administering batiraxcept in combination with already approved standard of care drugs. Therefore, our success will be dependent upon the continued use of and ability to obtain the standard of care drugs. We expect that in any other clinical trials we conduct for additional indications, our clinical product candidate will also be administered in combination with drugs owned by third parties. If any of the standard of care drugs that are used in our clinical trials are unavailable while the trials are continuing, the timeliness and commercialization costs could be impacted. In addition, if any of these other drugs are determined to have safety or efficacy problems, our clinical trials and commercialization efforts would be adversely affected.

If our product candidate, batiraxcept, requires or would commercially benefit from a companion diagnostic, and if we are unable to successfully validate, develop and obtain regulatory clearance or approval for such a companion diagnostic test, or experience significant delays in doing so, we may not realize the full commercial potential of our product candidates.

In connection with the clinical development of batiraxcept or other product candidates for certain indications, we may work with collaborators to develop or obtain access to in vitro companion diagnostic tests to identify patient subsets within a disease category who may derive selective and meaningful benefit from our drug candidates. Such companion diagnostics may be used during our clinical trials as well as in connection with the commercialization of our product candidates. To be successful, we or our collaborators will need to address a number of scientific, technical, regulatory and logistical challenges. The FDA and comparable foreign regulatory authorities regulate in vitro companion diagnostics as medical devices and, under that regulatory framework, will likely require the conduct of clinical trials to demonstrate the safety and effectiveness of any diagnostics we may develop, which we expect will require separate regulatory clearance or approval prior to commercialization. We may be unable to successfully validate, develop and obtain regulatory clearance or approval for any such companion diagnostic tests or may experience delays in doing so, which could materially harm or limit the commercial potential of our product candidates.

Our clinical product candidate, batiraxcept, may exhibit undesirable side effects when used alone or in combination with other approved pharmaceutical products, which may delay or preclude its development or regulatory approval, or limit its use if ever approved.

Throughout the drug development process, we must continually demonstrate the activity, safety and tolerability of batiraxcept, in order to obtain regulatory approval to further advance our clinical development, or to eventually market it. Even if our clinical product candidate demonstrates adequate biologic activity and clear clinical benefit, any unacceptable side effects or adverse events, when administered alone or in the presence of other pharmaceutical products, may outweigh these potential benefits. We may observe adverse or serious adverse events or drug-drug interactions in preclinical studies or clinical trials of batiraxcept, which could result in the delay or termination of its development, prevent regulatory approval, or limit its market acceptance if it is ultimately approved.

For our clinical product candidate, batiraxcept, we rely upon one third party to manufacture its drug substance. Any problems experienced by either our third-party manufacturer or our vendors could result in a delay or interruption in the supply of batiraxcept to us until the third-party manufacturer or its vendor cures the problem or until we locate and qualify an alternative source of manufacturing and supply.

For our clinical product candidate, batiraxcept, we currently rely on one third-party manufacturer located in China to manufacture batiraxcept for our clinical studies and that manufacturer purchases materials from our third-party vendors and transports the materials necessary to produce batiraxcept, such as the required reagents and containers. If a virus should spread to the districts in which our manufacturer’s facilities are located, we could experience delays in manufacturing and shipments of our clinical product, which could result in clinical trial delays.  If the third-party manufacturer were to experience any prolonged disruption for our manufacturing, we could be forced to seek additional third-party manufacturing contracts, thereby increasing our development costs and negatively impacting our timelines and any commercialization costs. If we change manufacturers at any point during the development process or after approval of a product candidate, we will be required to demonstrate comparability between the product manufactured by the old manufacturer and the product manufactured by the new manufacturer. If we are unable to do so we may need to conduct additional clinical trials with product manufactured by the new manufacturer.

If our manufacturer is not able to manufacture sufficient quantities of batiraxcept, our development activities would be impaired. In addition, the manufacturing facility where our clinical product candidate, batiraxcept, is manufactured is subject to ongoing, periodic inspection by the FDA or other comparable regulatory agencies to ensure compliance with cGMP. Any failure to follow and document the manufacturer’s adherence to such cGMP regulations or other regulatory requirements may lead to significant delays in the availability of clinical bulk drug substance and finished product for clinical trials, which may result in the termination of or a hold on a clinical trial, or may delay or prevent filing or approval of marketing applications for batiraxcept. We also may encounter problems with the following:

If we encounter any of these problems or are otherwise delayed, or if the cost of manufacturing in the China facility is not economically feasible or we cannot find another third-party manufacturer, we may not be able to produce our clinical product candidate, batiraxcept, in a sufficient quantity to meet future demand.

In addition, since we rely on a third-party manufacturer located in China, our business is subject to risks associated with doing business in China, including:

These risks are likely to be exacerbated by our limited experience with our current products and manufacturing processes. If demand for our products materializes, we may have to invest additional resources to purchase materials, hire and train employees, and enhance our manufacturing processes. It may not be possible for us to manufacture our clinical product candidate, batiraxcept, at a cost or in quantities sufficient to make its clinical product candidate commercially viable. Any of these factors may affect our ability to manufacture our products and could reduce gross margins and profitability.

Reliance on third-party manufacturers and suppliers entails risks to which we would not be subject if we manufactured batiraxcept ourself, including:

If our contract manufacturer or its suppliers fail to deliver the required commercial quantities of our clinical product candidate, batiraxcept, required for our clinical trials and, if approved, for commercial sale, on a timely basis and at commercially reasonable prices, and we are unable to find one or more replacement manufacturers or suppliers capable of production at a substantially equivalent cost, in substantially equivalent volumes and quality, and on a timely basis, we would likely be unable to meet demand for our products and would have to delay or terminate our pre-clinical or clinical trials, and we would lose potential revenue. It may also take a significant period of time to establish an alternative source of supply for batiraxcept and to have any such new source approved by the FDA or any applicable foreign regulatory authorities. Furthermore, any of the above factors could cause the delay or suspension of initiation or completion of clinical trials, regulatory submissions or required approvals of batiraxcept, cause it to incur higher costs and could prevent us from commercializing batiraxcept successfully.

We may not be able to manufacture batiraxcept in sufficient quantities for commercialization.

In order to receive FDA approval of our clinical product candidate, batiraxcept, we will need to manufacture such clinical product candidate in larger quantities. Our third-party manufacturer may not be willing or able to increase successfully the manufacturing capacity for batiraxcept in a timely or economic manner, or at all. In the event FDA approval is received, we will need to increase production of batiraxcept. Significant scale-up of manufacturing may require additional validation studies, which the FDA must review and approve. If we are unable to successfully increase the manufacturing capacity for batiraxcept, the clinical trials as well as the regulatory approval or commercial launch of batiraxcept may be delayed or there may be a shortage in supply. Batiraxcept requires precise, high quality manufacturing. Failure to achieve and maintain high quality manufacturing, including the incidence of manufacturing errors, could result in patient injury or death, delays or failures in testing or delivery, cost overruns or other problems that could harm our business, financial condition and results of operations.

In the event that we need to change our third-party contract manufacturer, our preclinical studies or our clinical trials, the commercialization of our clinical product candidate, batiraxcept, could be delayed, adversely affected or terminated, or such a change may result in the need for us to incur significantly higher costs, which could materially harm our business.

Due to various regulatory restrictions in the United States and many other countries, as well as potential capacity constraints on manufacturing that occur from time-to-time in our industry, various materials in the manufacturing of batiraxcept are solely-sourced from certain contract manufacturers. In accordance with cGMPs, changing manufacturers may require the re-validation of manufacturing processes and procedures, and may require further preclinical studies or clinical trials to show comparability between the materials produced by different manufacturers. Changing our current or future contract manufacturers may be difficult, if not impossible for us, and could be extremely costly if we do make such a change, which could result in our inability to manufacture batiraxcept for an extended period of time and a delay in the development of batiraxcept. Further, in order to maintain our development timelines in the event of a change in a third-party contract manufacturer, we may incur significantly higher costs to manufacture batiraxcept.

If third-party vendors, upon whom we rely to conduct our preclinical studies or clinical trials, do not perform or fail to comply with strict regulations, these studies or trials may be delayed, terminated, or fail, or we could incur significant additional expenses, which could materially harm our business.

We have limited resources dedicated to designing, conducting and managing our preclinical studies and clinical trials. We have historically relied on, and intend to continue to rely on, third parties, including CROs, consultants and principal investigators, to assist us in designing, managing, conducting, monitoring and analyzing the data from our preclinical studies and clinical trials. We rely on these vendors and individuals to perform many facets of the clinical development process on our behalf, including conducting preclinical studies, the recruitment of sites and subjects for participation in our clinical trials, maintenance of good relations with the clinical sites, and ensuring that these sites are conducting our trials in compliance with the trial protocol and applicable regulations. If these third parties fail to perform satisfactorily, or do not adequately fulfill their obligations under the terms of our agreements with them, we may not be able to enter into alternative arrangements without undue delay or additional expenditures, and therefore the preclinical studies and clinical trials of our clinical product candidate, batiraxcept, may be delayed or prove unsuccessful.

Further, the FDA, the EMA, or similar regulatory authorities in other countries, may inspect some of the clinical sites participating in our clinical trials or our third-party vendors’ sites to determine if our clinical trials are being conducted according to good clinical practices, or GCPs, or similar regulations. If we or a regulatory authority determine that our third-party vendors are not in compliance with, or have not conducted our clinical trials according to applicable regulations, we may be forced to exclude certain data from the results of the trial, or delay, repeat or terminate such clinical trials.

We rely on third parties to conduct, supervise and monitor our clinical trials, and if those third parties perform in an unsatisfactory manner, it may harm our business.

We rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials, and we expect to have limited influence over their actual performance.

We also rely upon CROs to monitor and manage data for our clinical programs, as well as the execution of future nonclinical studies. We expect to control only certain aspects of our CROs’ activities. Nevertheless, we will be responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards and our reliance on the CROs does not relieve us of our regulatory responsibilities.

We and our CROs will be required to comply with the Good Laboratory Practices and GCPs, which are regulations and guidelines enforced by the FDA and are also required by the Competent Authorities of the Member States of the EEA and comparable foreign regulatory authorities in the form of International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use guidelines for any of our product candidates that are in preclinical and clinical development. The Regulatory authorities enforce GCPs through periodic inspections of trial sponsors, principal investigators and clinical trial sites. If we or our CROs fail to comply with GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. Accordingly, if our CROs fail to comply with these regulations or fail to recruit a sufficient number of subjects, we may be required to repeat clinical trials, which would delay the regulatory approval process and increase our costs.

Our CROs are not our employees, and we do not control whether or not they devote sufficient time and resources to our future clinical and nonclinical programs. These CROs may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials, or other drug development activities which could harm our competitive position. We face the risk of potential unauthorized disclosure or misappropriation of our intellectual property by CROs, which may reduce our trade secret protection and allow our potential competitors to access and exploit our proprietary technology. If our CROs do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for any other reasons, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for, or successfully commercialize any product candidate that we develop. As a result, our financial results and the commercial prospects for any product candidate that it develops would be harmed, its costs could increase, and our ability to generate revenues could be delayed.

If our relationship with these CROs terminate, we may not be able to enter into arrangements with alternative CROs or do so on commercially reasonable terms. Switching or adding additional CROs involves substantial cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. Though we intend to carefully manage our relationships with our CROs, there can be no assurance that it will not encounter challenges or delays in the future or that these delays or challenges will not have an adverse impact on our business, financial condition and prospects.

Our future success depends on our ability to retain executive officers and attract, retain and motivate qualified personnel.

We are highly dependent on our executive officers and the other principal members of our management and scientific teams. The employment of our executive officers is at-will and our executive officers may terminate their employment at any time. The loss of the services of any of our senior executive officers could impede the achievement of our research, development and commercialization objectives. We do not maintain “key person” insurance for any executive officer or employee.

Recruiting and retaining qualified scientific, clinical, manufacturing and sales and marketing personnel is also critical to our success. We may not be able to attract and retain these personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. Our industry has experienced an increasing rate of turnover of management and scientific personnel in recent years. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist it in devising our research and development and commercialization strategy. Our consultants and advisors may be employed by third parties and have commitments under consulting or advisory contracts with other entities that may limit their availability to advance our strategic objectives. If any of these advisors or consultants can no longer dedicate a sufficient amount of time to the company, our business may be harmed.

Many of the other pharmaceutical companies that we compete against for qualified personnel and consultants have greater financial and other resources, different risk profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high-quality candidates and consultants than what it has to offer. If we are unable to continue to attract and retain high-quality personnel and consultants, the rate and success at which we can select and develop our clinical product candidate, batiraxcept, and our business will be limited.

Risks Related to Clinical Development, Regulatory Approval and Commercialization

If the results from preclinical studies or clinical trials of batiraxcept are unfavorable, we could be delayed or precluded from its further development or commercialization, which could materially harm our business.

In order to further advance the development of, and ultimately receive marketing approval to sell batiraxcept, we must conduct extensive preclinical studies and clinical trials to demonstrate our safety and efficacy to the satisfaction of the FDA or similar regulatory authorities in other countries, as the case may be. Preclinical studies and clinical trials are expensive, complex, can take many years to complete, and have highly uncertain outcomes. Delays, setbacks, or failures can and do occur at any time, and in any phase of preclinical or clinical testing, and can result from concerns about safety, tolerability, toxicity, a lack of demonstrated biologic activity or improved efficacy over similar products that have been approved for sale or are in more advanced stages of development, poor study or trial design, and issues related to the formulation or manufacturing process of the materials used to conduct the trials. The results of prior preclinical studies or early-stage clinical trials are not predictive of the results we may observe in late-stage clinical trials, especially since the number of subjects in our completed clinical trials was small.  In many cases, product candidates in clinical development may fail to show the desired tolerability, safety and efficacy characteristics, despite having favorably demonstrated such characteristics in preclinical studies or early-stage clinical trials.

In addition, we may experience numerous unforeseen events during, or as a result of, preclinical studies and the clinical trial process, which could delay or impede our ability to advance the development of, receive marketing approval for, or commercialize our clinical product candidate, batiraxcept, including, but not limited to:

Even if the data collected from preclinical studies or clinical trials involving batiraxcept, demonstrate a satisfactory tolerability, safety and efficacy profile, such results may not be sufficient to support the submission of a BLA to obtain regulatory approval from the FDA in the United States, or other similar regulatory authorities in other foreign jurisdictions, which is required for us to market and sell batiraxcept.

Clinical trials are very expensive, time-consuming, difficult to design and implement and involve an uncertain outcome, and if they fail to demonstrate safety and efficacy to the satisfaction of the FDA, or similar regulatory authorities, we will be unable to commercialize our clinical product candidate, batiraxcept.

Batiraxcept is still in clinical development and will require extensive additional clinical testing before we are prepared to submit a BLA for regulatory approval for any indication or for any treatment regime. We cannot predict with any certainty if or when we might submit a BLA for regulatory approval for batiraxcept, or whether any such future BLA would be approved by the FDA. Human clinical trials are very expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. For instance, the FDA may not agree with endpoints for any clinical trial we propose, which may delay the commencement of our clinical trials. The clinical trial process is also time-consuming. Furthermore, failure can occur at any stage of the trials, and we could encounter problems that cause us to abandon or repeat clinical trials. A product candidate 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, and the results of our Phase 1 clinical trial of the clinical product candidate as well as the pre-clinical results may not be predictive of the results of our Phase 2 or Phase 3 trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles.

Moreover, preclinical and clinical data are often susceptible to multiple interpretations and analyses. Many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their products. Success in preclinical testing and early clinical trials does not ensure that later clinical trials, which involve many more subjects and the results of later clinical trials may not replicate the results of prior clinical trials and preclinical testing.  For example, during 2022 we revised the statistical analysis plan for our adaptive design Phase 3 trial of batiraxcept in PROC by omitting the interim analysis in the trial.  Although we believe we can enroll the number of bevacizumab naïve patients needed to have a potentially successful study, our belief may be incorrect, and we may ultimately have negative trial results or indeterminate trial results that are not able to support BLA approval.

If we are required to conduct additional clinical trials or other testing of batiraxcept beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of batiraxcept or other testing, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:

Product development costs will also increase if we experience delays in testing or in receiving marketing approvals. We do not know whether any clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our clinical product candidate, batiraxcept, could allow our competitors to bring products to market before we do, and could impair our ability to successfully commercialize batiraxcept, any of which may harm our business and results of operations.

Enrollment and retention of subjects in clinical trials is an expensive and time-consuming process and could be made more difficult or rendered impossible by multiple factors outside our control.

We may encounter delays in enrolling, or be unable to enroll, a sufficient number of participants to complete our ongoing enrolling clinical trials and future clinical trials. Even if we rare able to enroll a sufficient number of patients, once enrolled, we may be unable to retain a sufficient number of participants to complete any of our trials. Late-stage clinical trials of batiraxcept may require the enrollment and retention of large numbers of subjects. Subject enrollment and retention in clinical trials depends on many factors, including the size of the subject population, the nature of the trial protocol, the existing body of safety and efficacy data with respect to the trial drug, the number and nature of competing treatments and ongoing clinical trials of competing drugs for the same indication, the proximity of subjects to clinical sites and the eligibility criteria for the trial.

Furthermore, any negative results we may report in clinical trials of batiraxcept, negative results reported from clinical trials conducted by our collaborators or negative results of similar product candidates may make it difficult or impossible to recruit and retain participants in other clinical trials of that same clinical product candidate. Delays or failures in planned subject enrollment or retention may result in increased costs, program delays or both, which could have a harmful effect on its ability to develop its clinical product candidate, or could render further development impossible. In addition, we expect to rely on CROs and clinical trial sites to ensure proper and timely conduct of our future clinical trials and, while we intend to enter into agreements governing our services, we will be limited in our ability to compel their actual performance in compliance with applicable regulations. Enforcement actions brought against these third parties may cause further delays and expenses related to our clinical development programs.

We intend to seek FDA approval for batiraxcept for ccRCC through the use of the accelerated approval pathway. If we are unable to obtain such approval, we may be required to conduct additional clinical trials beyond those that we contemplate, which could increase the expense of obtaining, and delay the receipt of, necessary marketing approvals. Even if we receive accelerated approval from the FDA, if our confirmatory trials do not verify clinical benefit, or if we do not comply with rigorous post-marketing requirements, the FDA or comparable foreign regulatory authorities may seek to withdraw accelerated approval.

Under the accelerated approval program, the FDA may grant accelerated approval to a product candidate designed to treat a serious or life-threatening condition that provides meaningful therapeutic benefit over available therapies upon a determination that the product candidate has an effect on a surrogate endpoint or intermediate clinical endpoint that is reasonably likely to predict clinical benefit. The FDA considers a clinical benefit to be a positive therapeutic effect that is clinically meaningful in the context of a given disease, such as irreversible morbidity or mortality. 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. An intermediate clinical endpoint is a clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit. The accelerated approval pathway may be used in cases in which the advantage of a new drug over available therapy may not be a direct therapeutic advantage, but is a clinically important improvement from a patient and public health perspective. If granted, accelerated approval is usually contingent on the sponsor’s agreement to conduct, in a diligent manner, additional post-approval confirmatory studies to verify and describe the product’s clinical benefit. If such post-approval studies fail to confirm the product’s clinical benefit, the FDA may withdraw its approval.

Prior to seeking accelerated approval for any of our product candidates, we intend to seek feedback from the FDA or similar foreign regulatory authorities and will otherwise evaluate our ability to seek and receive accelerated approval. There can be no assurance that after our evaluation of the feedback and other factors we will decide to pursue or submit a BLA or similar application for accelerated approval or any other form of expedited development or review. Similarly, there can be no assurance that after subsequent FDA or similar foreign regulatory authorities feedback we will continue to pursue or apply for accelerated approval or any other form of expedited development or review, even if we initially decide to do so. Furthermore, if we decide to submit an application for accelerated approval or other expedited development or review for our product candidates, there can be no assurance that such submission or application will be accepted or that any expedited development or review will be granted on a timely basis, or at all. The FDA or other comparable foreign regulatory authorities could also require us to conduct further studies prior to considering our application or granting approval of any type. A failure to obtain accelerated approval or any other form of expedited development or review for our product candidate would result in a longer time period to commercialization of such product candidate, if any, could increase the cost of development of such product candidate, and could harm our competitive position in the marketplace.

Fast Track designation for our product candidates may not lead to a faster development or regulatory review or approval process, and neither of these designations increases the likelihood that our product candidates will receive marketing approval.

We have obtained Fast Track designation for batiraxcept for PROC. If a drug or biologic candidate is intended for the treatment of a serious or life-threatening condition or disease and the drug demonstrates the potential to address unmet medical needs for the condition, the sponsor may apply for Fast Track designation. The receipt of Fast Track designation for a product candidate may not result in a faster development process, review or approval compared to products considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, the FDA may later decide that the product no longer meets the conditions for Fast Track designation.

It is possible that we may not be able to obtain or maintain orphan drug designation or exclusivity for our drug candidates, which could limit the potential profitability of our product candidates.

Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for the treatment or prevention of rare diseases or conditions with relatively small patient populations as orphan drugs. Under the Orphan Drug Act of 1983, the (“Orphan Drug Act”), the FDA may designate a product as an orphan drug if it is a drug intended to treat a rare disease or condition, which is defined as a patient population of fewer than 200,000 individuals in the United States. We received orphan drug designation from the FDA for batiraxcept for ovarian cancer from the EMA in October 2021. If a product with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the product is entitled to a seven-year period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same drug for the same indication during that time period with some exceptions. A similar provision in the European Union allows 10 years of exclusivity in Europe. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that marketing exclusivity is no longer justified. Orphan drug exclusivity may be lost in Europe under certain situations, such as the inability of the holder of the orphan drug designation to produce sufficient quantities of the drug to meet the needs of patients with the rare disease or condition or for certain other reasons.

We face significant competition from other biotechnology and pharmaceutical companies, and our operating results will suffer if we fail to compete effectively.

Development of cancer treatments is highly competitive and subject to rapid and significant technological advancements. In particular, we face competition from various sources, including larger and better funded pharmaceutical, specialty pharmaceutical and biotechnology companies, as well as academic institutions, governmental agencies and public and private research institutions. These competitors are focused on delivering therapeutics for the treatment of various cancers with products that are available and have gained market acceptance as the standard treatment protocol. Further, it is likely that additional drugs or other treatments will become available in the future for the treatment of certain cancers.

Many of our existing or potential competitors have substantially greater financial, technical and human resources than we do and significantly greater experience in the discovery and development of products for the treatment of cancer, as well as in obtaining regulatory approvals of those products in the United States and in foreign countries. Our current and potential future competitors also have significantly more experience commercializing drugs that have been approved for marketing. Mergers and acquisitions in the pharmaceutical and biotechnology industries could result in even more resources being concentrated among a small number of our competitors.

Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Our competitors may succeed in developing, acquiring or licensing, on an exclusive basis, drugs that are more effective or less costly than any product candidate that we may develop.

We will face competition from other drugs currently approved or that will be approved in the future for the treatment of the other infectious diseases we are currently targeting. Therefore, our ability to compete successfully will depend largely on our ability to:

The availability of our competitors’ products could limit the demand, and the price we are able to charge, for any product candidate we develop. The inability to compete with existing or subsequently introduced therapies would have an adverse impact on our business, financial condition and prospects.

Established pharmaceutical companies may invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make our product candidate less competitive. In addition, any new products that competes with an approved product must demonstrate compelling advantages in efficacy, convenience, tolerability and safety in order to overcome price competition and to be commercially successful. Accordingly, our competitors may succeed in obtaining patent protection, discovering, developing, receiving the FDA’s approval for or commercializing medicines before we do, which would have an adverse impact on our business and results of operations.

Our clinical product candidate, batiraxcept, may cause adverse effects or have other properties that could delay or prevent our regulatory approval or limit the scope of any approved label or market acceptance.

Adverse events caused by batiraxcept could cause reviewing entities, clinical trial sites or regulatory authorities to interrupt, delay or halt clinical trials and could result in the denial of regulatory approval. If an unacceptable frequency or severity of adverse events are reported in our clinical trials for batiraxcept, our ability to obtain regulatory approval for such clinical product candidate may be negatively impacted. In addition, adverse events caused by any clinical product candidate administered in combination with our product candidate could cause similar interruptions and delays, even though not caused by batiraxcept.

Furthermore, if any of our products are approved and then cause serious or unexpected side effects, a number of potentially significant negative consequences could result, including:

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate and could substantially increase the costs of commercialization.

Our employees, independent contractors, principal investigators, consultants, commercial collaborators, service providers and other vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have an adverse effect on our results of operations.

We are exposed to the risk that our employees and contractors, including principal investigators, consultants, commercial collaborators, service providers and other vendors may engage in fraudulent or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or other unauthorized activities that violate the laws and regulations of the FDA and other similar regulatory bodies, including those laws that require the reporting of true, complete and accurate information to such regulatory bodies, manufacturing standards, federal and state healthcare fraud and abuse and health regulatory laws and other similar foreign fraudulent misconduct laws, or laws that require the true, complete and accurate reporting of financial information or data. Misconduct by these parties may also involve the improper use or misrepresentation of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter third party misconduct, 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 it from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and financial results, including the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

If we are not able to obtain, or if there are delays in obtaining, required regulatory approvals, we will not be able to commercialize, or will be delayed in commercializing, our clinical product candidate, batiraxcept, and our ability to generate revenue will be impaired.

Batiraxcept and the activities associated with our development and commercialization, including our design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDA and other regulatory agencies in the United States and by comparable authorities in other countries. Failure to obtain marketing approval for a clinical product candidate will prevent us from commercializing the clinical product candidate. We have not received approval to market batiraxcept from regulatory authorities in any jurisdiction. We only have limited experience in filing and supporting the applications necessary to gain marketing approvals and expect to rely on CROs to assist us in this process. Securing regulatory approval requires the submission of extensive preclinical and clinical data and supporting information to the various regulatory authorities for each therapeutic indication to establish the clinical product candidate’s safety and efficacy. Securing regulatory approval also requires the submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, the relevant regulatory authority. Batiraxcept may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may prevent it from obtaining marketing approval or prevent or limit commercial use.

The process of obtaining marketing approvals, both in the United States and elsewhere, is expensive, may take many years and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidate involved. We cannot assure you that our product candidate will ever obtain any marketing approvals in any jurisdiction. The fact that the FDA has designated the investigation of batiraxcept for platinum-resistant recurrent ovarian cancer as a Fast Track development program, while potentially favorable, provides no assurance as to the timing or outcome of any FDA regulatory process. Fast Track status may be withdrawn if the conditions for such designation are no longer met. Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations or changes in regulatory review for each submitted product application may cause delays in the approval or rejection of an application. The FDA and comparable authorities in other countries have substantial discretion in the approval process and may refuse to accept any application or may decide that our data is insufficient for approval and require additional preclinical or other studies, and clinical trials. In addition, varying interpretations of the data obtained from preclinical testing and clinical trials could delay, limit or prevent marketing approval of a product candidate. Additionally, any marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable.

Even if we obtain FDA approval in the United States, we may never obtain approval for or commercialize our clinical product candidate, batiraxcept, in any other jurisdiction, which would limit our ability to realize each product’s full market potential.

In order to market batiraxcept in a particular jurisdiction, we must establish and comply with numerous and varying regulatory requirements on a country-by-country basis regarding safety and efficacy. Approval by the FDA in the United States does not ensure approval by regulatory authorities in other countries or jurisdictions and approval by regulatory authorities in other countries or jurisdictions does not ensure approval by the FDA. In addition, clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and regulatory approval in one country does not guarantee regulatory approval in any other country. Approval processes vary among countries and can involve additional product candidate testing and validation and additional administrative review periods. Seeking foreign regulatory approval could result in difficulties and costs for us and require additional preclinical studies or clinical trials which could be costly and time consuming. Regulatory requirements can vary widely from country to country and could delay or prevent the introduction of batiraxcept in those countries. We do not have any product candidates approved for sale in any jurisdiction, including in international markets, and we do not have experience in obtaining regulatory approval in international markets. If we or our collaborators fail to comply with regulatory requirements in international markets or to obtain and maintain required approvals, or if regulatory approvals in international markets are delayed, our target market will be reduced and our ability to realize the full market potential of any product candidate we develop will be unrealized.

Even if we obtain regulatory approval, we will still face extensive ongoing regulatory requirements and our clinical product candidate, batiraxcept, may face future development and regulatory difficulties.

Any product candidate for which we obtain marketing approval, along with the manufacturing processes, post-approval clinical data, labeling, packaging, distribution, adverse event reporting, storage, recordkeeping, export, import, advertising and promotional activities for such product candidate, among other things, will be subject to extensive and ongoing requirements of and review by the FDA and other regulatory authorities. These requirements include submissions of safety, efficacy and other post-marketing information and reports, establishment registration and drug listing requirements, continued compliance with cGMP requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance of records and documents, requirements regarding the distribution of samples to physicians and recordkeeping and current GCP requirements for any clinical trials that we conduct post-approval. Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product candidate may be marketed or to the conditions of approval. If batiraxcept receives marketing approval, the accompanying label may limit the approved use of our product, which could limit sales.

The FDA may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety and/or efficacy of batiraxcept. The FDA closely regulates the post-approval marketing and promotion of drugs to ensure drugs are marketed only for the approved indications and in accordance with the provisions of the approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use and if we do not market batiraxcept for its approved indications, we may be subject to enforcement action for off-label marketing. Violations of the Federal Food, Drug, and Cosmetic Act relating to the promotion of prescription drugs may lead to FDA enforcement actions and investigations alleging violations of federal and state health care fraud and abuse laws, as well as state consumer protection laws.

In addition, later discovery of previously unknown adverse events or other problems with batiraxcept, manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may yield various results, including:

The FDA’s policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of batiraxcept. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained.

Even if our clinical product candidate, batiraxcept, receives marketing approval, we may fail to achieve market acceptance by physicians, patients, third-party payors or others in the medical community necessary for commercial success.

If batiraxcept receives marketing approval, we may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. If we do not achieve an adequate level of acceptance, we may not generate significant revenues and become profitable. The degree of market acceptance, if approved for commercial sale, will depend on a number of factors, including but not limited to:

Because we expect sales of all of batiraxcept to be based on the same mechanism of action, the failure of our first product candidate to achieve market acceptance would harm our business and could require us to seek additional financing sooner than we otherwise planned.

The insurance coverage and reimbursement status of newly-approved products is uncertain. Our product candidates may become subject to unfavorable pricing regulations, third-party coverage and reimbursement practices, or healthcare reform initiatives, which would harm our business. Failure to obtain or maintain adequate coverage and reimbursement for new or current products could limit our ability to market those products and decrease our ability to generate revenue.

The regulations that govern marketing approvals, pricing, coverage, and reimbursement for new drugs vary widely from country to country. In the United States, recently enacted legislation may significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining approvals. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenue we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if any product candidates we may develop obtain marketing approval.

Our ability to successfully commercialize our product candidates also will depend in part on the extent to which coverage and adequate reimbursement for these products and treatments will be available from government health administration authorities, private health insurers, and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. The availability of coverage and extent of reimbursement by governmental and private payors is essential for most patients to be able to afford treatments such as gene therapy products. Sales of these or other product candidates that we may identify will depend substantially, both domestically and abroad, on the extent to which the costs of our product candidates will be paid by health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or reimbursed by government health administration authorities, private health coverage insurers and other third-party payors. If coverage and adequate reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize our product candidates. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain pricing sufficient to realize a sufficient return on our investment.

The availability and extent of reimbursement by governmental and private payors is essential for most patients to be able to afford expensive treatments. Sales of batiraxcept that receive marketing approval will depend substantially, both in the United States and internationally, on the extent to which the costs of batiraxcept will be paid by health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or reimbursed by government health administration authorities, private health coverage insurers and other third-party payors. If reimbursement is not available, or is available only on a limited basis, we may not be able to successfully commercialize batiraxcept. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain adequate pricing that will allow it to realize a sufficient return on our investment.

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, China and other countries may cause us to price batiraxcept on less favorable terms that we currently anticipate. In many countries, particularly the countries of the European Union, the prices of medical products are subject to varying price control mechanisms as part of national health systems. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of batiraxcept to other available therapies. In general, the prices of products under such systems are substantially lower than in the United States. Other countries allow companies to fix their own prices for products but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that is able to be charged for clinical product candidates. Accordingly, in markets outside the United States, the reimbursement for products may be reduced compared with the United States and may be insufficient to generate commercially reasonable revenues and profits.

Moreover, increasing efforts by governmental and third-party payors, in the United States and internationally, to cap or reduce healthcare costs may cause such organizations to limit both coverage and level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for clinical product candidates. We expect to experience pricing pressures in connection with the sale of batiraxcept 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 for new products entering the marketplace.

If we fail to comply with state and federal healthcare regulatory laws, we could face substantial penalties, damages, fines, disgorgement, exclusion from participation in governmental healthcare programs, and the curtailment of operations, any of which could harm our business.

Although we do not provide healthcare services or submit claims for third party reimbursement, we are subject to healthcare fraud and abuse regulation and enforcement by federal and state governments which could significantly impact our business. The laws that may affect our ability to operate include, but are not limited to:

Further, the ACA, among other things, amended the intent requirements of the federal anti-kickback statute and certain criminal statutes governing healthcare fraud. A person or entity can now be found guilty of violating the statute without actual knowledge of the statute or specific intent to violate it. In addition, the ACA provided that the government may assert that a claim including items or services resulting from a violation of the federal Anti- Kickback Statute constitutes a false or fraudulent claim for purposes of the FCA. If a government authority were to conclude that we provide improper advice to our customers or encouraged the submission of false claims for reimbursement, we could face action against us by government authorities. Any violations of these laws, or any action against us for violation of these laws, even if we successfully defend against it, could result in a material adverse effect on our reputation, business, results of operations and financial condition.

We have entered into consulting and scientific advisory board arrangements with physicians and other healthcare providers. Compensation for some of these arrangements includes the provision of stock options. While we have worked to structure our arrangements to comply with applicable laws, because of the complex and far-reaching nature of these laws, regulatory agencies may view these transactions as prohibited arrangements that must be restructured, or discontinued, or for which we could be subject to other significant penalties. We could be adversely affected if regulatory agencies interpret our financial relationships with providers who influence the ordering of and use our products to be in violation of applicable laws.

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.

Responding to investigations can be time- and resource-consuming and can divert management’s attention from the business. Additionally, as a result of these investigations, healthcare providers and entities may have to agree to additional onerous compliance and reporting requirements as part of a consent decree or corporate integrity agreement. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business.

Product liability lawsuits against us could cause us to incur substantial liabilities and could limit the commercialization of any product candidates we may develop.

We face an inherent risk of product liability exposure related to the testing of batiraxcept in human clinical trials and will face an even greater risk if we commercially sell any products that we may develop after approval. Any adverse reactions in our clinical trials could be deemed to be related to batiraxcept and could result in claims from these injuries and we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

Although we maintain product liability insurance coverage in the amount of up to $10 million per claim and in the aggregate $000 million, we may not be adequate to cover all liabilities that we may incur. We anticipate that we will need to increase our insurance coverage as we continue clinical trials and if we successfully commercialize any products. Insurance coverage is increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise.

If we are unable to establish sales, marketing and distribution capabilities either on our own or in collaboration with third parties, we may not be successful in commercializing our clinical product candidate, batiraxcept, if approved.

We do not have any infrastructure for the sales, marketing or distribution of batiraxcept, and the cost of establishing and maintaining such an organization may exceed the cost-effectiveness of doing so. In order to market any product candidate that may be approved, we must build our sales, distribution, marketing, managerial and other non-technical capabilities or make arrangements with third parties to perform these services. To achieve commercial success for any product candidate for which we have obtained marketing approval, we will need a sales and marketing organization. We expect to build a focused sales, distribution and marketing infrastructure to market any other product candidates in the United States, if approved. There are significant expenses and risks involved with establishing our own sales, marketing and distribution capabilities, including our ability to hire, retain and appropriately incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel, and effectively manage a geographically dispersed sales and marketing team. Any failure or delay in the development of our internal sales, marketing and distribution capabilities could delay any product candidate launch, which would adversely impact commercialization.

Factors that may inhibit our efforts to commercialize batiraxcept on our own include:

We intend to pursue collaborative arrangements regarding the sale and marketing of batiraxcept, if approved, for certain international markets; however, we may not be able to establish or maintain such collaborative arrangements, if able to do so, that our collaborators may not have effective sales. To the extent that we depend on third parties for marketing and distribution, any revenues we receive will depend upon the efforts of such third parties, and there can be no assurance that such efforts will be successful.

If we are unable to build our own sales force in the United States or negotiate a collaborative relationship for the commercialization of batiraxcept outside the United States we may be forced to delay the potential commercialization or reduce the scope of our sales or marketing activities. We may have to enter into arrangements with third parties or otherwise at an earlier stage than we would otherwise choose and we may be required to relinquish rights to our intellectual property or otherwise agree to terms unfavorable to us, any of which may have an adverse effect on our business, operating results and prospects.

We may be competing with many companies that currently have extensive and well-funded marketing and sales operations. Without an internal team or the support of a third party to perform marketing and sales functions, we may be unable to compete successfully against these more established companies.

If we obtain approval to commercialize our clinical product candidate, batiraxcept outside of the United States, a variety of risks associated with international operations could harm our business.

If our clinical product candidate is approved for commercialization, we intend to enter into agreements with third parties to market them in certain jurisdictions outside the United States such as we have with 3D Medicine. We expect that we will be subject to additional risks related to international operations or entering into international business relationships, including:

We have no prior experience in these areas. In addition, there are complex regulatory, tax, labor and other legal requirements imposed by both the European Union and many of the individual countries in Europe as well as China with which we will need to comply.

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our clinical product candidate, batiraxcept, and affect the prices we may obtain.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could, among other things, prevent or delay marketing approval of our clinical product candidate, restrict or regulate post-approval activities and affect our ability to profitably sell any product candidate 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 or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect our business, financial condition and results of operations.

Among policy makers 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 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, subjects biological products to potential competition by lower-cost biosimilars, addresses 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, increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the rebate program to individuals enrolled in Medicaid managed care organizations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs, and creates a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 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.

Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges. Congress has considered legislation that would repeal or repeal and replace all or part of the ACA, and it is unclear how such challenges and other efforts to repeal and replace the ACA will impact the ACA and our business.

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.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products, which could result in reduced demand for batiraxcept or additional pricing pressures. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors.

Risks Related to Our Intellectual Property

If we are unable to obtain and maintain patent protection for our clinical product candidate, batiraxcept, or if the scope of the patent protection obtained is not sufficiently broad, we may not be able to compete effectively in our markets.

We rely upon a combination of patents, trade secret protection and confidentiality agreements to protect the intellectual property related to our drug development programs and clinical product candidate. Our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries. We seek to protect our proprietary position by filing patent applications in the United States and abroad related to our development programs and clinical product candidate. The patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner.

It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. The patent applications that we own or in-license may fail to result in issued patents with claims that cover our product candidates in the United States or in other countries. There is no assurance that all potentially relevant prior art that could invalidate our patents or that could prevent our pending patent applications from issuing as patents have been found. Even if patents do successfully issue, third parties may challenge their validity, enforceability or scope, which may result in such patents being narrowed, invalidated, or held unenforceable. Any successful challenge to these patents or any other patents owned by or licensed to us could deprive us of rights necessary for the successful commercialization of our product candidates or companion diagnostic that we may develop. Further, if we encounter delays in regulatory approvals, the period of time during which we could market a product candidate and companion diagnostic under patent protection could be reduced.

If the patent applications we hold with respect to our platform technology and clinical product candidate fail to issue, if their breadth or strength of protection is threatened, or if they fail to provide meaningful exclusivity for batiraxcept, it could dissuade companies from collaborating with us to develop future product candidates and threaten our ability to commercialize future drugs. Any such outcome could harm our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has in recent years been the subject of much litigation. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States. For example, European patent law restricts the patentability of methods of treatment of the human body more than U.S. law does. Publications of discoveries in 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 owned or licensed patents or pending patent applications, or that we were the first to file for patent protection of such inventions. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued that protect our technology or product candidates, in whole or in part, or which effectively prevent others from commercializing competitive technologies. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection.

Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of ours issued patents. In 2011, the Leahy-Smith America Invents Act (the "Leahy-Smith Act"), was signed into law. The Leahy-Smith Act includes a number of significant changes to United States patent law. These include provisions that affect the way patent applications are prosecuted and may also affect patent litigation. The U.S. Patent Office recently developed new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions, only became effective in 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act 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, all of which could have an adverse effect on our business and financial condition.

Moreover, we may be subject to a third party pre-issuance submission of prior art to the USPTO, or become involved in derivation, reexamination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others. In other countries, we may be subject to or become involved in opposition proceedings challenging our patent rights or the patent rights of others. An adverse determination in any such submission or proceeding could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or product candidates and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize product candidates without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and owned and licensed patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and product candidates. Moreover, patents have a limited lifespan. In the United States and other countries, the natural expiration of a patent is generally 20 years after it is filed. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited. Without patent protection for our current or future product candidates, we may be open to competition from generic versions of such product candidates. 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, we owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing product candidates similar or identical to ours.

We may be involved in lawsuits to protect or enforce our patents, the patents of our licensors or our other intellectual property rights, which could be expensive, time consuming and unsuccessful.

Competitors and other third parties may infringe or otherwise violate our patents, the patents of our licensors, of our licensees or our other intellectual property rights. To counter infringement or unauthorized use, we may be required to file legal claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent of ours or our licensors is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that such patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing. The initiation of a claim against a third party may also cause the third party to bring counter claims against us such as claims asserting that our patents are invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, nonenablement or lack of statutory subject matter. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant material information from the USPTO, or made a materially misleading statement, during prosecution. Third parties may also raise similar validity claims before the USPTO in post-grant proceedings such as inter partes review, or post-grant review, or oppositions or similar proceedings outside the United States, in parallel with litigation or even outside the context of litigation. The outcome following legal assertions of invalidity and unenforceability is unpredictable. We cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. For the patents and patent applications that we have licensed, we may have limited or no right to participate in the defense of any licensed patents against challenge by a third party. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of any future patent protection on our current or future product candidates. Such a loss of patent protection could harm our business.

We may not be able to prevent, alone or with our licensors or licensees, misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the United States. Our business could be harmed if in litigation the prevailing party does not offer us a license on commercially reasonable terms. Any litigation or other proceedings to enforce our intellectual property rights may fail, and even if successful, may result in substantial costs and distract our management and other employees.

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 an adverse effect on the price of our common stock.

Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our clinical product candidate, batiraxcept.

The United States has recently enacted and implemented wide-ranging patent reform legislation. The United States Supreme Court has ruled on several 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 actions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce patents that we have licensed or that we might obtain in the future.

If a third party claims we are infringing on their intellectual property rights, we could incur significant expenses, or be prevented from further developing or commercializing our clinical product candidate, batiraxcept, which could materially harm our business.

Our success will also depend on our ability to operate without infringing the patents and other proprietary intellectual property rights of third parties. This is generally referred to as having “freedom to operate.” We have not conducted an in-depth freedom to operate search which would be time consuming and costly. The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual property rights. The defense and prosecution of intellectual property claims, interference proceedings and related legal and administrative proceedings, both in the United States and internationally, involve complex legal and factual questions. As a result, such proceedings are lengthy, costly and time-consuming, and their outcome is highly uncertain. We may become involved in protracted and expensive litigation in order to determine the enforceability, scope and validity of the proprietary rights of others, or to determine whether we have freedom to operate with respect to the intellectual property rights of others. For example, we are aware of U.S. Patent Nos. 8,168,415 and 8,920,799, which claim AXL fusion proteins and their use in treating cancer. In the event that one of these patents or another patent is successfully asserted against our GAS6-AXL program in the future, we may be unable to market the product, absent a license from the patentee, which may not be available on commercially reasonable terms, if at all.

Patent applications in the United States are, in most cases, maintained in secrecy until approximately 18 months after the patent application is filed. The publication of discoveries in the scientific or patent literature frequently occurs substantially later than the date on which the underlying discoveries were made. Therefore, patent applications relating to product candidates similar to ours may have already been filed by others without our knowledge. In the event that a third party has also filed a patent application covering batiraxcept, we may have to participate in an adversarial proceeding, such as an interference proceeding, in the USPTO, or similar proceedings in other countries, to determine the priority of invention. In the event an infringement claim is brought against us, we may be required to pay substantial legal fees and other expenses to defend such a claim and, if we are unsuccessful in defending the claim, we may be prevented from pursuing the development and commercialization of a product candidate and may be subject to injunctions and/or damage awards.

In the future, the USPTO or a foreign patent office may grant patent rights covering batiraxcept to third parties. Subject to the issuance of these future patents, the claims of which will be unknown until issued, we may need to obtain a license or sublicense to these rights in order to have the appropriate freedom to further develop or commercialize them. Any required licenses may not be available to us on acceptable terms, if at all. If we need to obtain such licenses or sublicenses, but are unable to do so, we could encounter delays in the development of batiraxcept, or be prevented from developing, manufacturing and commercializing batiraxcept at all. If it is determined that we have infringed an issued patent and do not have freedom to operate, we could be subject to injunctions, and/or compelled to pay significant damages, including punitive damages. In cases where we have in-licensed intellectual property, our failure to comply with the terms and conditions of such agreements could harm our business.

It is becoming common for third parties to challenge patent claims on any successfully developed product candidate or approved drug. If we or our licensees or collaborators become involved in any patent litigation, interference or other legal proceedings, we could incur substantial expense, and the efforts and attention of our technical and management personnel could be significantly diverted. A negative outcome of such litigation or proceedings may expose us to the loss of our proprietary position or to significant liabilities, or require us to seek licenses that may not be available from third parties on commercially acceptable terms, if at all. We may be restricted or prevented from developing, manufacturing and selling batiraxcept in the event of an adverse determination in a judicial or administrative proceeding, or if we fail to obtain necessary licenses.

We may not be able to protect our intellectual property rights throughout the world, which could impair our business.

Filing, prosecuting and defending patents covering batiraxcept throughout the world would be prohibitively expensive. Competitors may use our 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 may obtain patent protection, but where patent enforcement is not as strong as that in the United States. These other products may compete with batiraxcept in jurisdictions where we do not have any issued or licensed patents and any future patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so competing.

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed.

We seek to protect our proprietary technology in part by entering into confidentiality agreements with third parties and, if applicable, material transfer agreements, consulting agreements or other similar agreements with our advisors, employees, third-party contractors and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, including our trade secrets. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other unauthorized use or disclosure would impair our competitive position and may have an adverse effect on our business and results of operations.

In addition, these agreements typically restrict the ability of our advisors, employees, third-party contractors and consultants to publish data potentially relating to our trade secrets, although our agreements may contain certain limited publication rights. Despite our efforts to protect our trade secrets, our competitors may discover our trade secrets, either through breach of our agreements with third parties, independent development or publication of information by any of our third-party collaborators. A competitor’s discovery of our trade secrets would impair our competitive position and have an adverse impact on our business.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submissions, 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 fees on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary fee payments 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, but are not limited to, 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 and our licensors fail to maintain the patents and patent applications covering batiraxcept, our competitive position would be adversely affected.

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:

Should any of these events occur, they could significantly harm our business, results of operations and prospects.

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

Many of our employees, including our senior management, were previously employed at other biotechnology or pharmaceutical companies. These employees typically executed proprietary rights, non-disclosure and non-competition agreements in connection with their previous employers. 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 intellectual property, including trade secrets or other proprietary information, of any such employee’s former employer. We are not aware of any threatened or pending claims related to these matters, but in the future litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

Risks Related to the Ownership of Our Common Stock

Our failure to meet the continued listing requirements of The Nasdaq Global Select Market could result in a delisting of our common stock.

Our shares of common stock are currently listed on The Nasdaq Global Select Market ("Nasdaq"). If we fail to satisfy the continued listing requirements of Nasdaq, such as the corporate governance requirements, minimum bid price requirement or the minimum stockholder’s equity requirement, The Nasdaq Stock Market LLC may take steps to delist our common stock. Any delisting would likely have a negative effect on the price of our common stock and would impair stockholders’ ability to sell or purchase their common stock when they wish to do so.

On August 9, 2022, we received written notice from the Listing Qualifications Department of The Nasdaq Stock Market LLC notifying us that for the preceding 30 consecutive business days (June 27, 2022 through August 8, 2022), our common stock did not maintain a minimum closing bid price of $1.00 per share (“Minimum Bid Price Requirement”) as required by Nasdaq Listing Rule 5550(a)(2). In November 2022 we received written notice from the Listing Qualifications Department of The Nasdaq Stock Market LLC that we had regained compliance with Nasdaq’s listing requirements. We can provide no assurance that we will be able to continue to meet Nasdaq listing requirements. Any future failure to meet the listing requirements or a delisting of our common stock by Nasdaq could adversely affect our ability to attract new investors, decrease the liquidity of the outstanding shares of our common stock, reduce the price at which such shares trade and increase the transaction costs inherent in trading such shares with overall negative effects for our stockholder. In addition, delisting of our common stock from Nasdaq could deter broker-dealers from making a market in or otherwise seeking or generating interest in our common stock, and might deter certain institutions and persons from investing in our common stock.

Our stock price has fluctuated in the past, has recently been volatile and may be volatile in the future, and as a result, investors in our common stock could incur substantial losses.

Our stock price has fluctuated in the past, has recently been volatile and may be volatile in the future. From January 1, 2022 through December 31, 2022 the reported high and low sales price of our common stock has fluctuated between $0.58 and $2.84 per share. The stock market in general and the market for biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may experience losses on their investment in our common stock. The market price for our common stock may be influenced by many factors, including the following:

These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. Since the stock price of our common stock has fluctuated in the past, has been recently volatile and may be volatile in the future, investors in our common stock could incur substantial losses. In the past, following periods of volatility in the market, securities class-action litigation has often been instituted against companies. Such litigation, if instituted against us, could result in substantial costs and diversion of management’s attention and resources, which could materially and adversely affect our business, financial condition, results of operations and growth prospects.  

Our executive officers, directors, and entities under our control, and principal stockholders will continue to maintain the ability to control or significantly influence all matters submitted to stockholders for approval.

As of March 10, 2023, our current executive officers, directors and entities under their control, and principal stockholders, in the aggregate, owned shares representing approximately 60.2% of our common stock. Dr. Fredric N. Eshelman, our Executive Chairman beneficially owns 55.5% of our common stock. As a result, Dr. Eshelman acting on his own, would be able to control or significantly influence all matters submitted to our stockholders for approval, as well as our management and affairs. For example, Dr. Eshelman will control or significantly influence the election of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of voting power could delay or prevent an acquisition of our company on terms that other stockholders may desire.

We incur significant costs as a result of operating as a public company, and our management devotes substantial time to new compliance initiatives.

As a public company, we have incurred and will continue to incur significant legal, accounting and other expenses that we did not incur as a private company. We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, the other rules and regulations of the SEC, and the rules and regulations of Nasdaq. Compliance with the various reporting and other requirements applicable to public companies requires considerable time and attention of management. For example, the Sarbanes-Oxley Act and the rules of the SEC and national securities exchanges have imposed various requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls. Our management and other personnel are devoting and will continue to need to devote a substantial amount of time to these compliance initiatives. These rules and regulations will continue to increase our legal and financial compliance costs and will make some activities more time-consuming and costly. The impact of these events could also make it more difficult for us to attract and retain qualified personnel to serve on our board of directors, our board committees, or as executive officers.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we must perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. In addition, we will be required to have our independent registered public accounting firm attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10-K following the date on which we are once again an accelerated filer and are no longer an emerging growth company. Our compliance with Section 404 of the Sarbanes-Oxley Act will require that we incur substantial accounting expense and expend significant management efforts. If we are not able to comply with the requirements of Section 404 in a timely manner, or if we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.

Our ability to successfully implement our business plan and comply with Section 404 requires us to be able to prepare timely and accurate consolidated financial statements. We expect that we will need to continue to improve existing, and implement new operational and financial systems, procedures and controls to manage our business effectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations to suffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls from our auditors as required under Section 404 of the Sarbanes-Oxley Act. This, in turn, could have an adverse impact on trading prices for our common stock, and could adversely affect our ability to access the capital markets.

We are currently a “smaller reporting company,” as defined in the Exchange Act and have elected to take advantage of certain of the scaled disclosures available to smaller reporting companies which may make our stock less attractive to investors.

We are currently a “smaller reporting company,” as defined in the Exchange Act and have elected to take advantage of certain of the scaled disclosures available to smaller reporting companies. To the extent that we continue to qualify as a “smaller reporting company” as such term is defined in Rule 12b-2 under the Exchange Act, certain exemptions are available to us from certain disclosure requirements that are applicable to other public companies that are not a “smaller reporting company,” including exemption from compliance with the auditor attestation requirements pursuant to SOX and reduced disclosure about our executive compensation arrangements.

As a result, the information we provide stockholders will be different than the information that is available with respect to other public companies. In this Annual Report on Form 10-K, we have not included all of the executive compensation related information that would be required if we were not a smaller reporting company, nor have we included all of the quantitative and qualitative disclosures about market risk that would be required if we were not a smaller reporting company. We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock, and our stock price may be more volatile.

An active trading market for our common stock may not be maintained, or we may fail to satisfy applicable Nasdaq listing requirements.

Our common stock is currently traded on Nasdaq, but we can provide no assurance that we will be able to maintain an active trading market for our shares on Nasdaq or any other exchange in the future. The fact that a significant portion of our outstanding shares of common stock is closely held by a few individuals, results in it being more difficult for us to maintain an active trading market. If there is no active market for our common stock, it may be difficult for our stockholders to sell shares without depressing the market price for the shares or at all, our stock price could decline, and we may be unable to maintain compliance with applicable Nasdaq listing requirements.

If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, our stock price and trading volume could decline.

The trading market for our common stock depends, in part, on the research and reports that securities or industry analysts publish about us or our business. The analysts that cover us may cease to publish research on our company at any time in their discretion. If one or more of these analysts cease coverage of our company, or fail to publish reports on us regularly, demand for our common stock could decrease, which might cause our stock price and trading volume to decline. In addition, if one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If our operating results fail to meet the forecast of analysts, our stock price would likely decline.

Provisions in our corporate charter documents and under Delaware law and certain of our outstanding warrants could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our corporate charter and our bylaws may discourage, delay or prevent a merger, acquisition or other change in control of us that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Because our board of directors is responsible for appointing the members of our management team, these provisions could in turn affect any attempt by our stockholders to replace current members of our management team. Among others, these provisions include the following:

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

Certain provisions of certain of our outstanding warrants could make it more difficult or expensive for a third party to acquire us. Certain of the warrants prohibit us from engaging in certain transactions constituting “fundamental transactions” unless, among other things, the surviving entity assumes our obligations under the warrants. Further, such warrants provide that, in the event of certain transactions constituting “fundamental transactions,” with some exception, holders of such warrants will have the right, at their option, to require us to repurchase such warrants at a designated price.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for certain disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for any derivative action or proceeding brought on behalf of the Company, any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or the Company’s stockholders, any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or any action asserting a claim governed by the internal affairs doctrine. This forum selection provision does not apply to suits brought to enforce a duty or liability created by the Securities Act or the Exchange Act or any claim for which the federal courts have exclusive jurisdiction.

This forum selection provision may limit a stockholder’s ability to bring certain claims in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. If a court were to find this forum selection provision to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

Our employment arrangements with our executive officers may require us under certain circumstances to pay severance benefits.

Certain of our executive officers are parties to employment or other agreements or participants under plans that contain change in control and severance provisions providing for aggregate cash payments for severance and other benefits and acceleration of vesting of stock options in the event of a termination of employment in connection with a change in control of us. The accelerated vesting of options could result in dilution to our existing stockholders and harm the market price of our common stock. The payment of these severance benefits could harm our financial condition and results. In addition, these potential severance payments may discourage or prevent third parties from seeking a business combination with us.

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, will be our stockholders’ sole source of gain.

We have never declared or paid cash dividends on our common stock. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business. In addition, the terms of existing or any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be our stockholders’ sole source of gain for the foreseeable future.  

Item 1B. Unresolved Staff Comments.

None

Item 2. Properties.

We do not own any real property and lease facilities in Morrisville, North Carolina, Menlo Park, California and Houston, Texas.  Our principal executive offices are located in Houston, Texas where we occupy office space pursuant to the terms of a lease agreement that expires on October 31, 2023, which will automatically renew at the end of the term for a six-month term, unless a three-month notice is given to cancel. Our rent under the lease is approximately $1,800 per month.

In March 2017, we entered into an operating facility lease agreement with Bohannon Associates, a California partnership, dated March 17, 2017 (the “Master Lease”) for approximately 34,500 rentable square feet of office space located at 1020 Marsh Road, Menlo Park, California (the “1020 Marsh Facility”). The lease for the 1020 Marsh Facility commenced in August 2017 for a period of 86 months with one renewal option for a five-year term. Future base rent we owe over the lease term as of December 31, 2021 is $8.3 million.

On August 1, 2021, the sublease dated June 8, 2021 (the “Sublease Agreement”) by and between us and Grail, Inc., or Grail (“Subtenant”) became effective, whereby we agreed to sublease to Subtenant all of the approximately 34,500 rentable square feet of office space at the 1020 Marsh Facility currently leased pursuant to the Master Lease. The sublease commenced on August 1, 2021 and the term of the sublease was through October 31, 2024, unless the Master Lease was terminated earlier due to a breach by Subtenant. Base rent Subtenant was obligated to pay us as of December 31, 2021 was $6.7 million.

In August 2020, we entered into an operating facility lease agreement with Perimeter Center 7 Pack, LLC dated August 14, 2020 for approximately 4,128 square feet of office space at 1800 Perimeter Park Suite 130, Morrisville, North Carolina. Future base rent we owe over the lease term as of December 31, 2022 is $0.5 million.  

We believe that our existing facilities are adequate for our current needs.

Item 3. Legal Proceedings.

We are not currently subject to any material legal proceedings. From time to time, we may be subject to various legal proceedings and claims that arise in the ordinary course of its business activities. Litigation, regardless of the outcome, could have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Market for Registrant’s Common Equity

Since October 16, 2018, our common stock has been listed on Nasdaq under the symbol “ARAV”.  Prior to that, from March 21, 2014 until October 16, 2018, our common stock traded on Nasdaq under the symbol “VSAR”.  In connection with the completion of the Merger, on October 15, 2018, our amended and restated certificate of incorporation was amended to effect, on October 16, 2018, a reverse split of our common stock at a ratio of 1-for-6.

Holders

On March 10, 2023, there were 36 stockholders of record of our common stock, one of which was Cede & Co., a nominee for Depository Trust Company, or DTC. All of the shares of our common stock held by brokerage firms, banks and other financial institutions as nominees for beneficial owners are deposited into participant accounts at DTC and are therefore considered to be held of record by Cede & Co. as one stockholder.

Dividend Policy

We have not paid dividends on our common stock. We currently intend to retain any earnings for use in the development and expansion of our business. We, therefore, do not anticipate paying cash dividends on our common stock in the foreseeable future.

Sales of Unregistered Equity Securities

There were no unregistered sales of equity securities by us during the year ended December 31, 2022 that were not previously disclosed in our filings with the SEC.

Issuer Purchases of Equity Securities

There were no issuer purchases of equity securities during the fourth quarter of the year ended December 31, 2022.

Performance Graph

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information required under this item.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K. This discussion and other parts of this Form 10-K contain forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section of this Form 10-K entitled “Risk Factors.”

Important Note

This Management’s Discussion and Analysis of Financial Condition and Results of Operations includes a discussion of our operations for the years ended December 31, 2022 and December 31, 2021.

References in this report to “we,” “us,” “our” and similar first-person expressions refer to Aravive, Inc. (formerly known as Versartis, Inc.) and its subsidiaries, including Private Aravive. References to “Versartis, Inc.” or “Private Aravive” refer to those respective companies prior to the completion of their merger in October 2018.

Overview

We are a clinical-stage oncology company developing transformative treatments designed to halt the progression of life-threatening diseases, including cancer and fibrosis.

Batiraxcept (formerly AVB-500), is an ultrahigh-affinity, decoy protein that targets the GAS6-AXL signaling pathway. By capturing serum GAS6, batiraxcept starves the AXL pathway of its signal, potentially halting the biological programming that promotes disease progression. AXL receptor signaling plays an important role in multiple types of malignancies by promoting metastasis, cancer cell survival, resistance to treatments, and immune suppression.

Our current development program benefits from the availability of a proprietary serum-based biomarker that has accelerated batiraxcept drug development by allowing us to select a pharmacologically active dose and may potentially identify the cancer patients that have the best chance of responding to batiraxcept.

In our completed Phase 1 clinical trial in healthy volunteers with batiraxcept, we have demonstrated proof of mechanism for batiraxcept in neutralizing GAS6. Importantly, batiraxcept had a favorable safety profile preclinically and in the first in human trial and Phase 1b clinical trial in cancer patients.

In August 2018, the FDA designated as a Fast Track development program the investigation of batiraxcept for platinum-resistant recurrent ovarian cancer.

In December 2018, we initiated our Phase 1b clinical trial of batiraxcept combined with standard of care therapies in patients with PROC, for which we reported results in July 2020.

In April 2020, we entered into a license and collaboration agreement with WuXi, the objective of which is to identify and develop novel high-affinity bispecific antibodies against CCN2, also known as CTGF, implicated in cancer and fibrosis and identified from a similar target discovery screen that identified the significance of the AXL/GAS6 pathway in cancer. However, in August 2022, the Company temporarily halted work on the CTGF program with WuXi in an effort to focus all resources on the clinical programs.

In November 2020, we entered into the 3D Medicines Agreement, whereby we granted 3D Medicines an exclusive license to develop and commercialize products that contain batiraxcept as the sole drug substance, for the diagnosis, treatment or prevention of human oncological diseases, in the Territory.

During the fourth quarter of 2020, we initiated our Phase 1b portion of the Phase 1b/2 trial of batiraxcept in ccRCC and we dosed our first patient in the trial in March 2021.

During the first quarter 2021, we initiated our registrational Phase 3 trial of batiraxcept in PROC and we dosed our first patient in the trial in April 2021.This global, randomized, double-blind, placebo-controlled trial is designed to evaluate efficacy and safety of batiraxcept at a dose of 15 mg/kg in combination with PAC versus PAC alone.

In May 2021, we announced expansion of batiraxcept development programs into first line pancreatic ductal adenocarcinoma ("PDAC") with the goal of initiating the trial by end of 2021. We dosed our first patient in August 2021.

In June 2021, we announced initial safety, pharmacokinetic, and pharmacodynamic results from the batiraxcept Phase 1b portion of the Phase 1b/2 clinical trial in ccRCC.

In October 2021, the EMA granted orphan drug designation for batiraxcept for the treatment of PROC, following a recommendation from the Committee for Orphan Medicinal Products.

In November 2021, we announced preliminary data from our Phase 1b trial evaluating batiraxcept in combination with cabozantinib for treatment of ccRCC.

In January 2022, we announced that we had dosed the first patient in the Phase 2 portion of the Phase 1b/2 study of batiraxcept in combination with cabozantinib for treatment of ccRCC.

In March 2022, we announced updated data and new biomarker data from our Phase 1b trial of batiraxcept in ccRCC.

In May 2022, we provided updated data and information at our Key Opinion Leader symposium.

In October 2022, we received a $6 million development milestone payment from 3D Medicines based on the initiation of the global Phase 3 platinum resistant ovarian cancer ("PROC") clinical trial in the Territory for the development of batiraxcept.

In November 2022, the FDA designated as a Fast Track development program the investigation of batiraxcept for treatment of patients with advanced or metastatic ccRCC who have progressed after 1 or 2 prior lines of systemic therapy that include both immuno-oncology (IO)-based and vascular endothelial growth factor tyrosine kinase inhibitor (VEGF-TKI)-based therapies (either in combination or sequentially).

In January 2023, the Company announced complete enrollment in the global Phase 3 platinum resistant ovarian cancer ("PROC") clinical trial.

Recent Clinical Developments

The Phase 3 Platinum Resistant Ovarian Cancer (PROC) Trial Remains On Track

The registration-directed Phase 3 program of batiraxcept in combination with paclitaxel in PROC remains on track and enrollment has been completed. We expect to report topline data from the trial by mid-2023. CMC work remains on track with the goal of filing a BLA by year-end 2023. The global, randomized, double-blind, placebo-controlled Phase 3 trial is evaluating efficacy and tolerability of batiraxcept at a dose of 15 mg/kg in combination with paclitaxel versus placebo in combination with paclitaxel. The trial has completed enrollment of over 360 patients with platinum resistant, high-grade serous ovarian cancer who have received 1-4 prior lines of therapy.

Updated Clear Cell Renal Cell Cancer Data (ccRCC) Continues to Be Encouraging

As of August 8, 2022, 26 previously treated (2L+) patients with ccRCC have been treated with batiraxcept in the Phase 1b portion of a Phase 1b/2 trial at doses of 15 mg/kg (n=16) and 20 mg/kg (n=10), plus cabozantinib 60 mg daily. There were no dose limiting toxicities observed at either dose. The best overall response rate (ORR, confirmed) in the ITT population was 42%. One of the objectives of the ongoing Phase 1b/2 ccRCC trial is to evaluate the correlation of baseline serum soluble AXL (sAXL)/GAS6 (biomarker) with radiographic response in patients with ccRCC treated with batiraxcept plus cabozantinib. The best ORR in the biomarker high population was 55%. The 9-month progression-free survival (PFS) rate was 65% in the ITT population and 72% in the biomarker high population. We have discussed a registrational path with the US FDA that includes use of the sAXL/Gas6 ratio as a basis for an accelerated approval.

We expect to report additional data from the Phase 1b portion and preliminary data from the Phase 2 portion of the ccRCC trial mid-2023. 

Expansion of Phase 1b Pancreatic Adenocarcinoma Study

As of September 20, 2022, 18 patients with pancreatic adenocarcinoma (“PDAC”) had been treated with 15 mg/kg (Days 1 & 15) + nab-paclitaxel (125 mg/m2 on Days 1, 8, & 15) and gemcitabine (1000 mg/m2 on Days 1, 8, & 15) and have pharmacokinetic data. As has been seen for other Phase 1b cancer studies with batiraxcept, there is a relationship between batiraxcept exposures and clinical activity such that 5 out of the 9 patients in the PDAC study whose batiraxcept levels exceeded the minimum efficacious concentration (MEC) of batiraxcept had a response vs 1 out of 9 patients in the low MEC group. Similarly, the mPFS in the high MEC group was 5.6 months (95% CI 2.1, not evaluable) vs 2.7 months (95% CI 1.1, 5.4) in the low MEC group. In May 2022, we had reported that batiraxcept in combination with gemcitabine and nab-paclitaxel was generally well-tolerated with no unexpected safety signals. Based on these data, we intend to dose an additional 6-18 patients at higher doses (20mg/kg and potentially 25mg/kg) to see if higher doses will increase the proportion of patients who will achieve high MEC of batiraxcept and increase the clinical activity of batiraxcept in combination with gemcitabine + nab-paclitaxel.

Recent Financial Developments

In January 2022, we entered into an investment agreement (the “Investment Agreement”) with Eshelman Ventures, LLC  and, solely for purposes of Article IV and Article V of the Investment Agreement, Dr. Eshelman, Eshelman Ventures, agreed to purchase pre-funded warrants of up to 4,545,455 shares of  our common stock, par value $0.0001 per share (“Warrant Shares”), at a price of $2.20 per share, which was the consolidated closing bid price of our common stock on Nasdaq on December 31, 2021, for an aggregate purchase price of $10 million.  The closing of the transaction occurred on January 5, 2022. Pursuant to the terms of the Investment Agreement, we were required to file a registration statement registering the shares of common stock underlying the pre-funded warrant.  The registration statement was filed on January 5, 2022 and declared effective by the SEC on January 18, 2022. The pre-funded warrants issued to Eshelman Ventures, LLC were exercisable upon the approval by our stockholders of the exercise, which approval was obtained on April 1, 2022, at which time the pre-funded warrants were exercised in full.

On March 31, 2022, we closed a registered direct offering of our common stock with a single healthcare-focused institutional investor and Eshelman Ventures, LLC, pursuant to which we issued 3,185,216 shares of common stock, 1,665,025 pre-funded warrants (the “March Pre-Funded Warrants”) and common stock warrants (the “Common Stock Warrants”) to purchase up to 4,850,241 shares of common stock in a registered direct offering priced at-the-market under Nasdaq rules. The purchase price per share and accompanying common stock warrant was $2.005 for the institutional investor and $2.325 for Eshelman Ventures, LLC.  The purchase price per March Pre-Funded Warrant and accompanying Common Stock Warrant was $2.004 for the institutional investor.  The net proceeds from the offering were $9.3 million, after deducting underwriting discounts, commission and offering expenses.  The Common Stock Warrants issued to the institutional investor are exercisable immediately, will expire five years from the exercisable date and will have an exercise price of $1.88 per share. The Common Stock Warrants issued to Eshelman Ventures, LLC were exercisable upon the approval by our stockholders of the exercise of previously issued securities, which approval was obtained on April 1, 2022, will expire five years following the exercise date and will have an exercise price of $2.20 per share. We could receive additional gross proceeds of $9.4 million, if the Common Stock Warrants are fully exercised.  The 1,665,025 Pre-Funded Warrants were exercised on June 6, 2022.

On October 27, 2022, we closed a private placement offering with new biotechnology investors, existing investors, our management and certain of our directors for the issuance and sale of an aggregate of 45,178,811 shares of our common stock, or pre-funded warrants in lieu thereof (the “October Pre-Funded Warrants” and together with the March Pre-Funded Warrants, the “Pre-Funded Warrants”) and warrants (the “October Warrants” and together with the March Common Warrant, the “Warrants”) to purchase up to an aggregate of 45,178,811 shares of common stock or pre-funded warrants (the “Private Placement”) priced at-the-market under Nasdaq rules. The purchase price per share and accompanying warrant was $0.9199 for all investors who participated in the deal (or $0.9198 per pre-funded warrant and accompanying October Warrant). Fifty percent of the October Warrants have an exercise price of $0.7949 per share and will expire on the date that is the later of: (i) 15 months from the date an increase in the number of authorized shares of common stock is effected, or (ii) one month after the public announcement of the topline Phase 3 PROC data. The remaining 50% of the October Warrants have an exercise price of $0.7949 per share and will expire 30 months from the date an increase in the number of authorized shares of common stock is effected. All of the October Warrants other than the October Pre-funded warrants are exercisable for exchange of cash from the warrant holder. The net proceeds were approximately $40 million and will be used to fund our clinical development programs. Pursuant to the terms of the registration rights agreements that we entered into, we were required to file a registration statement registering the shares of common stock issued and the shares of common stock underlying the October Warrants and October Pre-funded Warrants, underlying the pre-funded warrant.  The registration statement was filed on November 18, 2022 and declared effective by the SEC on November 28, 2022.

Financial overview

Revenue

To date, we have not generated any revenue from commercial sales of any of our product candidates. However, for the years ended December 31, 2022 and 2021, we generated approximately $9.1 million and $7.4 million from the 3D Medicine Agreement, which represents a portion of initial signing and milestone payments received from 3D Medicines that is recognized at the time of the receipt and a portion of the payments that is deferred and recognized over the PROC trial period.

In the future, we may generate revenue from a variety of sources, including product sales if we develop products which are approved for sale, license fees, milestones, research and development and royalty payments in connection with strategic collaborations or government contracts, or licenses of our intellectual property.

Research and development expenses

We recognize both internal and external research and development expenses as incurred. Our external research and development expenses consist primarily of:

Internal research and development costs consist primarily of salaries and related fringe benefit costs for our employees (such as workers’ compensation and health insurance premiums), stock-based compensation charges and travel costs.

General and administrative expenses

General and administrative expenses consist principally of personnel-related costs, professional fees for legal, consulting, audit and tax services, rent and other general operating expenses not included in research and development.

Other income (expense), net

Other income (expense), net is primarily comprised of sublease income for our 1020 Marsh Facility lease, gains and losses on foreign currency transactions related to third party contracts with foreign-based contract manufacturing organizations and change in fair value of the warrant liability.

Results of operations

Comparison of the years ended December 31, 2022 and 2021

The following table summarizes our net loss during the periods indicated (in thousands, except percentages):

Collaboration revenue

Collaboration revenue was approximately $9.1 million and $7.4 million for the years ended December 31, 2022 and 2021, respectively.  The increase in revenue in 2022 compared to the same period in 2021 was driven primarily by increased expenditures related to the Phase 3 PROC trial, which drives the recognition of deferred revenue over the trial period.

Research and development expense

Research and development expense increased by $29.4 million, or 78%, to $66.9 million in 2022 from $37.5 million in 2021. The increase was primarily due to the continued progress of our clinical programs, including our Phase 3 trial of batiraxcept in PROC, our Phase 1b/2 trial of batiraxcept in ccRCC, and our Phase 1 trial of batiraxcept in pancreatic cancer. The continued advancement of our Phase 3 trial of batiraxcept in PROC is the most significant driver to the increase in expense in 2022 when compared to the same period in 2021. There were also significant increased CMC manufacturing activities during 2022 in order to prepare for our BLA filing at the end of 2023.

General and administrative expense

General and administrative expense increased by approximately $2.5 million, or 24%, to approximately $13.0 million in 2022 from approximately $10.6 million for the same period in 2021. The increase was primarily driven by higher salary expense, higher stock-based compensation expense, higher severance expense, and increased consulting fees.

Total other income (expense), net

Total other income (expense), net fluctuated by approximately $7.0 million, to approximately $5.5 million of total other expense, net in 2022 from approximately $1.5 million of total other income, net in 2021. The change relates to sublease income received from our subtenant for a full year in 2022, compared to only a part of the year in 2021, offset by an increase in the fair value of our warrant liability totaling approximately $9.0 million for 2022.

Liquidity and Capital Resources

Since our inception and through December 31, 2022, we have financed our operations through private placements of our equity securities, public offerings of our equity securities, debt financing, CPRIT grant proceeds, sales of common stock through our at-the-market facility as well as payments received from license agreements. As of December 31, 2022, we had an accumulated deficit of approximately $616.1 million, primarily as a result of research and development and general and administrative expenses, and working capital of $35.9 million. As of December 31, 2022, we had cash and cash equivalents of approximately $53.7 million, a majority of which is invested in money market funds at several highly rated financial institutions.

During 2021 and 2022, our primary sources of funding have been milestone payments from 3D Medicines and proceeds from the sale of our common stock and other securities. In November 2020, June 2021 and August 2021, we received $12 million, $6 million and $3 million, respectively, in upfront and milestone payments from 3D Medicines pursuant to the 3D Medicines Agreement with them. In October 2022, we received a $6 million milestone payment from 3D Medicines. On February 18, 2021, we received approximately $21 million from the purchase by Eshelman Ventures of 2,875,000 shares of our common stock. On September 4, 2020, we entered into an equity distribution agreement (the "Equity Distribution Agreement") with Piper Sandler and Cantor Fitzgerald to sell shares of our common stock, from time to time, through an “at the market offering” program having an aggregate offering price of up to $60,000,000 through which Piper Sandler and Cantor Fitzgerald will act as sales agents. During the year ended December 31, 2021, we sold 1,432,627 shares of common stock for net proceeds of $9.8 million under the Equity Distribution Agreement.  On January 5, 2022, we received approximately $9.9 million in net proceeds from the purchase by Eshelman Ventures, LLC of pre-funded warrants to purchase up to 4,545,455 shares of our common stock. In March 2022, we received approximately $9.3 million in net proceeds, in the aggregate, from the purchase by Eshelman Ventures, LLC and a single healthcare-focused institutional investor of 3,185,216 shares of our common stock, 1,665,025 March Pre-Funded Warrants and March Common Stock Warrants to purchase up to 4,850,241 shares of our common stock in a registered direct offering. In October 2022, we received approximately $40 million in net proceeds from a private placement offering from new biotechnology investors, existing investors, our management and certain of our Directors for the issuance and sale of an aggregate of 45,178,811 shares of our common stock (or October Pre-Funded Warrants in lieu thereof) and October Common Warrants to purchase up to an aggregate of 45,178,811 shares of common stock in a private placement offering priced at-the-market under Nasdaq rules. The purchase price per share and accompanying October Common Warrant was $0.9199 for all investors who participated in the deal (or $0.9198 per October Pre-Funded Warrant and accompanying October Common Warrant). During the year ended December 31, 2022, we sold 54,763 shares of common stock for net proceeds of $0.1 million under the Equity Distribution Agreement. 

As of December 31, 2022, we had cash and cash equivalents of approximately $53.7 million. We believe that our existing cash and cash equivalents will be sufficient to sustain operations beyond our PROC Phase 3 top line results and into the fourth quarter of 2023 and that we will need to obtain additional financing in order to advance our clinical development program to later stages of development, build out our pipeline and fund operations beyond the fourth quarter of 2023. We intend to provide financing for the foregoing by seeking funds through equity or debt financings, collaborative or other arrangements with corporate sources, or through other sources of financing. These factors raised substantial doubt about our ability to continue as a going concern. The consolidated financial statements included in this Annual Report on Form 10-K do not include any adjustments relating to the recoverability of the recorded assets or the classification of liabilities that may be necessary should we be unable to continue as a going concern. Although management has been successful in raising capital in the past, there can be no assurance that we will be successful or that any needed financing will be available in the future at terms acceptable to us.  Our failure to raise capital as and when needed could have a negative impact on our financial condition and our ability to complete clinical trials and pursue our business strategies. We anticipate that we will need to raise substantial additional capital, the requirements of which will depend on many factors, including:

If we are unable to raise additional funds when needed, or if funds are raised on terms that are not favorable to us, we may be required to delay, reduce, or terminate some or all of our development programs and clinical trials. We may also be required to sell or license our technologies or clinical product candidates or programs that we would prefer to develop and commercialize ourselves.

Cash flows

The following table sets forth the primary sources and uses of cash and cash equivalents for each of the periods presented below:

Cash used in operating activities

Net cash used in operating activities was $65.1 million and $32.2 million during the years ended December 31, 2022 and 2021, respectively, which was primarily due to the use of funds in our operations related to the development of batiraxcept, our product candidate. Cash used in operating activities in 2022 increased compared to the year ended December 31, 2021 due primarily to the ramp up in our Phase 3 trial of batiraxcept in PROC along with continuing costs related to our trial of our second oncology indication, ccRCC and our third oncology indication, pancreatic adenocarcinoma. There were also significant increased CMC manufacturing activities during 2022 in order to prepare for our BLA filing at the end of 2023.

Cash used in investing activities

Net cash used in investing activities during the years ended December 31, 2022 and 2021 was $11 thousand and $0, respectively.

Cash provided by financing activities

Net cash provided by financing activities was $59.4 million and $31.1 million during the years ended December 31, 2022 and 2021, respectively. Financing activities related to the year ended December 31, 2022 included a registered direct offering of our securities with proceeds of $9.3 million, issuance of Pre-Funded Warrants with proceeds of $9.9 million, at the market offering proceeds of $0.1 million, and a private placement financing with net proceeds of approximately $40.0 million. Financing activities related to the year ended December 31, 2021 included a registered direct offering with proceeds of $20.9 million along with at the market offering proceeds of $9.8 million.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations is based upon financial statements that we have prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses, and related disclosures. On an on-going basis, we evaluate these estimates, including those related to revenue recognition and estimated future research and development expenses, warrant liabilities and share-based compensation. Estimates are based on historical experience, information received from third parties and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Historically, revisions to our estimates have not resulted in a material change to the financial statements.

Collaboration Revenue

We enter into out-license and collaboration agreements under which we license certain rights to our product candidate to third parties and which to date are within the scope of ASC 606. The terms of these arrangements typically include payment to us of one or more of the following: non-refundable, up-front license fees; development, regulatory, and commercial milestone payments; payments for manufacturing supply services we provide through our contract manufacturers; and royalties on net sales of licensed products. Each of these payments may result in license, collaboration and other revenue, except for revenues from royalties on net sales of licensed products, which are classified as royalty revenues.

For elements of our collaboration agreements that are accounted for pursuant to ASC 606, we must develop assumptions that require judgment to determine whether the individual promises should be accounted for as separate performance obligations or as a combined performance obligation, and to determine the stand-alone selling price for each performance obligation identified in the contract. We use key assumptions to determine the stand-alone selling price, which may include forecasted revenues, development timelines, reimbursement rates for personnel costs, discount rates, and probabilities of technical and regulatory success. If the license to our intellectual property is determined to be distinct from the other performance obligations identified in an out-license and collaboration arrangement, we recognize revenue from non-refundable, up-front fees allocated to the license when the license is transferred to the customer and the customer 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. With regard to the 3D Medicines collaboration agreements, we recognize revenue related to amounts allocated to the identified performance obligation on a proportional performance basis as the underlying services are performed.

The preceding estimates and judgments materially affect our recognition of collaboration revenues. Changes in our estimates of forecasted development costs could impact proportional performance percentages and could have a material effect on collaboration revenue recorded in the period in which we determine that change occurs.

Clinical Trial Accruals

Our clinical trial accruals are based on estimates of patient enrollment and related costs at clinical investigator sites as well as estimates for the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct and manage clinical trials on the Company’s behalf.

Our estimates of preclinical and clinical trial expenses are based on the services performed, pursuant to contracts with research institutions and CROs that conduct and manage preclinical studies and clinical trials on our behalf. In accruing service fees, we estimate the time period over which services will be performed and the level of patient enrollment and activity expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Payments made to third parties under these arrangements in advance of the receipt of the related services are recorded as prepaid expenses until the services are rendered.

The preceding estimates and judgment materially affect our research and development expenses.  Changes in our estimates of patient enrollment and related costs could have a material effect on our research and development expenses.

Stock-based Compensation Expense

For purposes of calculating stock-based compensation, we estimate the fair value of share-based compensation awards using a Black-Scholes option-pricing model. The determination of the fair value of stock-based compensation awards utilizing the Black-Scholes model is affected by our stock price and a number of assumptions, including but not limited to expected stock price volatility over the term of the awards and the expected term of stock options.

If factors change and we employ different assumptions, share-based compensation expense may differ significantly from what we have recorded in the past. If there is a difference between the assumptions used in determining stock-based compensation expense and the actual factors which become known over time, we may change the input factors used in determining stock-based compensation expense for future grants. These changes, if any, may materially impact our results of operations in the period such changes are made. For actual forfeitures, we recognize the adjustment to compensation expense in the period the forfeitures occur.

Warrant Liability

The Company estimates the fair value of these liabilities using assumptions that are based on the individual characteristics of the warrants on the valuation date and reporting date. The Company uses the Black-Scholes option-pricing model and the fair value of the underlying stock adjusted for discount for lack of marketability, when applicable, to determine the fair value of these liabilities. The valuation model is based on inputs as of the valuation dates, including the estimated volatility of our stock, the remaining contractual term of the warrants and the risk-free interest rates and various other factors.

If factors change and we employ different assumptions, the warrant liability and other income/expense may differ significantly from what we have recorded in the past. If there is a difference between the assumptions used in determining the warrant liability and the actual factors which become known over time, we might change our inputs used in the valuation model. These changes, if any, may materially impact our results of operations in the period such changes are made.

Information Regarding the Board of Directors and Corporate Governance

Independence of the Board of Directors

Our common stock is listed on Nasdaq. Under Nasdaq listing standards, independent directors must comprise a majority of a listed company’s board of directors and all members of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee must be independent. Audit Committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act and Compensation Committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Under Nasdaq listing standards, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

In order to be considered to be independent for purposes of Rule 10A-3, a member of an Audit Committee of a listed company may not, other than in his or her capacity as a member of the Audit Committee, the board of directors, or any other board committee: (i) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries, or (ii) be an affiliated person of the listed company or any of its subsidiaries.

The board of directors undertook a review of the independence of the members of the board of directors and considered whether any director has a material relationship with our company that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning their background, employment and affiliations, including family relationships, the board of directors has determined that all of our current directors, except Dr. Eshelman due to his position as Executive Chairman and Dr. McIntyre, due to her current position as President and Chief Executive Officer of our company, is “independent” as that term is defined under the rules of Nasdaq. As a result, Dr. Giaccia, Dr. Hohneker, Dr. Ho, Mr. Kirk, Mr. Rogers, and Mr. Zhang are deemed to be “independent” as that term is defined under the rules of Nasdaq.

In making these determinations, the board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances the board of directors deemed relevant in determining their independence, including the beneficial ownership of capital stock by each non-employee director, and the transactions involving them described in Item 13 of this Amendment “Certain Relationships and Related-Party Transactions, Director Independence.”

INFORMATION REGARDING COMMITTEES OF THE BOARD OF DIRECTORS

Item 11. Executive Compensation.

EXECUTIVE COMPENSATION

We are a “smaller reporting company” under Item 10 of Regulation S-K promulgated under the Exchange Act and the following compensation disclosure is intended to comply with the requirements applicable to smaller reporting companies. Although the rules allow us to provide less detail about our executive compensation program, the Compensation Committee is committed to providing the information necessary to help stockholders understand its executive compensation-related decisions. Accordingly, this section includes supplemental narratives that describe the 2022 executive compensation program for our named executive officers.

The following individuals are our “named executive officers” for the year ended December 31, 2022:

Oversight of Executive Compensation

The compensation of our named executive officers is determined and approved by our Compensation Committee, in discussion with the Chief Executive Officer with respect to the other named executive officers.  The Chief Executive Officer does not participate in discussions or decisions regarding her own compensation.

We believe that in order to create value for our stockholders, it is critical to attract, motivate and retain key executive talent by providing competitive compensation packages. Accordingly, we design our executive compensation programs to:

The Compensation Committee uses the services of an independent compensation consultant who is retained by, and reports directly to, the Compensation Committee to provide the Compensation Committee with an additional external perspective with respect to its evaluation of relevant market and industry practices. At the end of 2021, the Compensation Committee retained Korn Ferry, as a third-party compensation consultant to assist the Compensation Committee in establishing overall compensation levels for 2022. Korn Ferry conducted analyses and provided advice on, among other things, the appropriate peer group, executive compensation for our executive officers and compensation trends in the life sciences industry. The peer group was recommended by Korn Ferry and chosen by the Compensation Committee in late 2021 based on the following parameters: biopharmaceutical companies that were developing oncology products, with a lead product in a similar phase of development (Phase 1 or 2 clinical trials) as well as other appropriate financial and organizational metrics.

SUMMARY COMPENSATION TABLE

The following table shows compensation awarded to or earned by our named executive officers, for the fiscal years ended December 31, 2022 and 2021.

NARRATIVE TO SUMMARY COMPENSATION TABLE

The three principal components of our executive compensation program for our named executive officers in 2022 were base salary, annual performance-based bonus and long-term equity compensation. Base salary provides financial stability and security through a fixed amount of cash for performing job responsibilities. Annual performance-based bonus and long-term equity incentive compensation are designed to reward achievement of the specific strategic goals that we believe will advance our business strategy and create long-term value for our stockholders.

Consistent with our goal of attracting, motivating and retaining a high-caliber executive team, our executive compensation program is designed to pay for performance. We utilize compensation elements that meaningfully align our named executive officer’s interests with those of our stockholders to create long-term value. As such, a significant portion of our Chief Executive Officer’s and other executive officers’ compensation is “at risk”, performance-based compensation, in the form of long-term equity awards and annual cash incentives that are only earned if we achieve measurable corporate metrics, as set forth in the table below.

We do not have any formal policies for allocating compensation among salary, annual target cash incentive awards and equity grants, short-term and long-term compensation or among cash and non-cash compensation. Instead, the Compensation Committee uses its judgment in determining a total compensation program for each named executive officer to recommend to the Board for its approval that is a mix of current, short-term and long-term incentive compensation, that it believes appropriate to achieve the goals of our executive compensation program and our corporate objectives.

Annual Base Salary

In January 2022, the Compensation Committee reviewed the base salaries for our named executive officers, the market data from Korn Ferry, the scope of each executive’s responsibilities, each executive’s prior experience and internal pay equity. After such review, Dr. McIntyre’s annual base salary was raised from $500,000 to $510,000, and Mr. Shah’s annual base salary was raised from $370,800 to $381,924. In February 2022, we entered into an offer letter with Dr. Dove to serve as our Chief Operating Officer commencing March 25, 2022 at an annual base salary of $385,000.  In June 2022, Mr. Shah resigned as our Chief Financial Officer, and we entered into an offer letter with Mr. Howard to serve as our Chief Financial Officer at an annual base salary of $395,000. In February 2023, Dr. McIntyre's annual base salary was raised to $560,000, Mr. Howard's annual base salary was raised to $412,775, Dr. Dove's annual base salary was raised to $405,000. The named executive officers’ 2022 annual base salaries approved by the Compensation Committee were as follows:

Annual Cash Incentive (Performance-Based Award) Opportunity

In addition to base salaries, our named executive officers are eligible to earn an annual performance-based cash incentive award, which is designed to provide an appropriate incentive to our named executives to achieve defined annual corporate performance goals and to reward our executives for individual achievement towards these goals. The annual performance-based incentive award each executive officer is eligible to receive is based on the individual’s target incentive award, as a percentage of base salary. The amount of the performance-based bonus, if any, an executive earns may vary from year to year based on the achievement of certain corporate performance goals recommended by the Compensation Committee and communicated to our named executive officers each year, prior to or shortly following the beginning of the year to which they relate.

The corporate goals typically relate to our annual company goals and various business accomplishments which vary from time to time depending on our overall strategic objectives. The proportional emphasis on each goal may vary from time to time depending on our overall strategic objectives and the Compensation Committee’s and Board’s subjective determination of which goals have more impact on our performance.

Pursuant to their employment agreements or offer letters, each named executive officer was eligible to earn a 2022 target incentive award represented as a percentage of base salary as set forth below.

For 2022, the corporate goals primarily included clinical milestones and financing milestones. After careful review, our Compensation Committee and Board, concluded that we had achieved 105% of our corporate performance goals and therefore performance-based incentive awards were paid based upon 105% of target opportunities.

2022 Performance-Based Awards

After the end of the year, the Compensation Committee approves the extent to which the corporate goals have been achieved, based on management’s review and recommendation, however, our executives do not make recommendations with respect to their own achievement. Accordingly, whether or not any incentive award is awarded is determined in the Compensation Committee’s discretion. Bonuses are not earned or vested until they are awarded and paid. The Compensation Committee also considers any significant corporate events or other significant accomplishments that were not contemplated at the beginning of the performance period in determining the extent to which the strategic goals were satisfied, such as the circumstances surrounding the feasibility of a goal being achieved.

In February 2023, our Compensation Committee and Board approved the 2022 performance-based incentive awards set forth below related to 2022 performance based on the level of attainment of the 2022 specified goals.

Long-Term Incentive Compensation

Equity incentives are a key component of our executive compensation program that the Compensation Committee believes motivate executive officers to achieve our business objectives by tying incentives to the appreciation of our common stock. During 2022, we granted equity awards in the form of stock options that vest over a four-year period. Our long-term, equity-based incentive awards are designed to align the interests of our named executive officers and our other employees, non-employee directors and consultants with the interests of our shareholders. Because vesting is based on continued service, our equity-based incentives also encourage the retention of our named executive officers through the vesting period of the awards.

We use stock options as the primary incentive vehicle for long-term compensation to our named executive officers because they are able to profit from stock options only if our stock price increases relative to the stock option’s exercise price. We generally provide initial grants in connection with the commencement of employment of our named executive officers as our Compensation Committee, determines appropriate. We also provide annual grants shortly following the end of each year.

In January 2022, the Compensation Committee awarded stock option grants to our named executive officers in conjunction with the Board’s review of the 2021 corporate goals.  Dr. McIntyre was granted stock options to purchase 425,000 shares at an exercise price of $2.18 per share. Mr. Shah was granted stock options to purchase 175,000 shares at an exercise price of $2.18 per share.

In March 2022, Dr. Dove was granted stock options to purchase 200,000 shares at an exercise price of $1.89 per share upon his appointment as our Chief Operating Officer.

In June 2022, Mr. Howard was granted stock options to purchase 290,000 shares at an exercise price of $1.21 per share upon his appointment as our Chief Financial Officer. Upon resigning as Chief Financial Officer in June 2022 and per the terms of the separation agreement between Aravive, Inc. and Mr. Shah entered into on June 2, 2022, the vesting of Mr. Shah’s outstanding options to purchase a total of 403,207 shares was accelerated such that all such awards were fully vested on June 2, 2022.

In January 2023, the Compensation Committee approved and in February 2023, the Board awarded stock option grants to our named executive officers in conjunction with the Board’s review of the 2022 corporate goals.  Dr. McIntyre was granted stock options to purchase 700,000 shares at an exercise price of $1.67 per share. Mr. Howard and Dr. Dove were each granted stock options to purchase 400,000 shares at an exercise price of $1.67 per share.

Employee Benefit Plans

Our named executive officers are eligible to participate in our employee benefit plans, including our medical, dental, vision, group life and accidental death and dismemberment insurance plans, in each case, on the same basis as all of our other employees. We maintain a 401(k) plan for the benefit of our eligible employees, including our named executive officers, as discussed in the section below entitled “401(k) plan.”

In general, eligible compensation for purposes of the 401(k) plan includes an employee’s wages, salaries, fees for professional services and other amounts received for personal services actually rendered in the course of employment with us, to the extent the amounts are included in gross income, and subject to certain adjustments and exclusions required under the Code.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Severance Benefits Other Than in Connection With a Change in Control

The McIntyre Offer Letter provide that if we terminate any of their employment for any reason other than Cause or Permanent Disability (as defined in the Offer Letters), and not in connection with a change in control, if they (i) execute and do not revoke a release of claims within 60 days following the date of termination of employment with us and (ii) returns all of our property in his or her possession he or she will be entitled to (a) twelve months for  Dr. McIntyre of salary continuation payments (b) if he or she timely elects to continue her health insurance coverage under COBRA, we will pay a portion of him or her monthly COBRA premiums (at the same rate that we pay for active employees) for up to twelve months following the date he or she terminates employment with us (c) 12 months accelerated vesting of stock options and RSUs awarded to him or her and (d) up to 9 months post-termination to exercise any vested shares subject to such option. Mr. Howard’s Offer Letter provides that if he is terminated for any reason other than Cause or Permanent Disability and not in connection with a Change in Control (each as defined in the Howard Offer Letter), Mr. Howard will be eligible for certain severance benefits, including the following: (i) up to 12 months of base salary continuation; (ii) reimbursement of COBRA coverage; (iii) 12 months accelerated vesting of the stock options award to Mr. Howard and (iv) up to 12 months post-termination to exercise any vested shares subject to such stock options.

In addition, if terminated in connection with a change of control, severance benefits will be those specified under our 2019 Equity Incentive Plan and our Change in Control Severance Plan, which provides for specified severance benefits to certain eligible officers and employees of our company set forth below. In addition, if during the twelve-month period commencing on the closing date of a Change in Control we terminate his or her employment for any reason other than Cause or death or disability or he or she resigns for Good Reason, all unvested equity awards will immediately vest, subject to certain restriction. In addition, under the 2019 Equity Incentive Plan, if involuntarily terminated in connection with certain corporate transactions, including a change in control, Dr. McIntyre, Mr. Howard and Dr. Dove would be eligible for full accelerated vesting of her outstanding stock options and RSUs.

Change in Control Severance Benefit Plan

We have adopted a change in control severance benefit plan (the "severance plan"). The severance plan provides certain of our employees, including our currently employed Named Executive Officers, with severance payments and benefits upon certain qualifying terminations of employment within a one-year period following the closing of a change in control, as defined in the severance plan. The summary below is qualified by reference to the actual text of the severance plan, which is filed as an exhibit to the Form S-1, as amended, filed with the SEC on March 10, 2014.  

Under the severance plan, in the event of a participant’s involuntary termination without cause (and not due to death or disability) or if a participant resigns for good reason (as each terms is defined in the severance plan), if the participant in the severance plan (i) executes and does not revoke a release of claims within 60 days following the date he terminates employment with us and (ii) returns all of our property in his possession, he will be entitled to cash severance equal to the sum of his or her monthly base salary and monthly annual bonus target, multiplied by a severance multiplier, which is 15 in the case of the Chief Executive Officer and 12 in the case of the other C-Suite employees (which includes our named executive officers). In addition, following a qualifying termination, if a participant timely elects to continue his health insurance coverage under COBRA, we will pay a portion of his monthly COBRA premiums for a period of specified months following the date of termination.

All stock awards which are vested and exercisable as of the date of a qualifying termination under the severance plan (including by virtue of the provisions of the applicable equity plan) will remain outstanding and exercisable until the earliest to occur of (i) the last day of the applicable severance period, which is 15 months in the case of the Chief Executive Officer and 12 months in the case of the other C-Suite employees (ii) the expiration of the original term of such stock awards.

If one of our named executive officers is entitled to severance benefits under the severance plan by virtue of a qualifying termination of employment within 12 months following a change in control, he would not be entitled to severance benefits under the terms of his or her offer letter.

In addition, the severance plan provides that, except as otherwise expressly provided in an agreement between us and a participant, if any payment or benefit a participant would receive in connection with a change in control would constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code and such payment or benefit would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code, then such payment or benefit will be equal to either (i) the largest portion of the change in control payment that would result in no portion of the payment or benefit being subject to the excise tax, or (ii) the largest portion, up to and including the total payment or benefit, whichever amount, after taking into account all applicable taxes, including the excise tax (all computed at the highest applicable marginal rate), would result in the participant’s receipt, on an after-tax basis, of the greatest economic benefit to the participant, notwithstanding that all or some portion of the payment or benefit may be subject to the excise tax. If a reduction is so required, the reduction will occur in the order specified in the severance plan.
