SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS
This Quarterly Report on Form 10-Q includes forward-looking statements that reflect our current views with respect to our development programs, business strategy, business plan, financial performance and other future events. These statements include forward-looking statements both with respect to us, specifically, and our industry, in general. Such forward-looking statements include the words "expect," "intend,” "plan," "believe," "project," "estimate,” "may,” "should," "anticipate," "will" and similar statements of a future or forward-looking nature identify forward-looking statements.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Forward-looking statements are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. The COVID-19 pandemic has caused a widespread health crisis that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn that could impact our operating results. We expect the COVID-19 pandemic to continue to have both a direct and an indirect impact on our business operations and financial results, however, the extent of the impact on our clinical development and regulatory efforts, our corporate development objectives, our financial position and the value of and market for our common stock will depend on future developments that are highly uncertain and cannot be predicted with confidence at this time, such as the ultimate duration of the pandemic, the emergence of new variants of COVID-19, the emergence of new geographic hotspots where the coronavirus is spreading more rapidly, travel restrictions, quarantines, social distancing and business closure requirements in the United States and in other countries, as well as the effectiveness of actions taken globally to contain and treat the disease, including the availability of safe and effective vaccines and the uptake thereof, and whether existing vaccines are effective with respect to new variants. There are or will be important factors that could cause actual results to differ materially from those indicated in these statements. These factors include, but are not limited to, those factors set forth in the sections captioned "Business – Overview,” “Risk Factors,” “Legal Proceedings,” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in this Quarterly Report on Form 10-Q, in our Annual Report on Form 10-K for the year ended December 31, 2020 as filed with the Securities and Exchange Commission ("SEC") on March 23, 2021 ("2020 Annual Report") and in our other public filings with the SEC, all of which you should review carefully. We undertake no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law.

1. Description of Business

Overview

SELLAS Life Sciences Group, Inc. (the "Company" or "SELLAS") is a late-stage clinical biopharmaceutical company focused on novel cancer immunotherapeutics for a broad range of cancer indications. SELLAS’ lead product candidate, galinpepimut-S ("GPS"), is a cancer immunotherapeutic agent licensed from Memorial Sloan Kettering Cancer Center ("MSK") and targets the Wilms Tumor 1 ("WT1") protein, which is present in 20 or more cancer types. Based on its mechanism of action as a directly immunizing agent, GPS has potential as a monotherapy or in combination with other immunotherapeutic agents to address a broad spectrum of hematologic, or blood, cancers and solid tumor indications. SELLAS’ second product candidate, nelipepimut-S ("NPS"), is a cancer immunotherapy targeting the human epidermal growth factor receptor 2 ("HER2") expressing cancers with potential for the treatment of patients with early stage breast cancer with low to intermediate HER2 expression, otherwise known as HER2 1+ or 2+, which includes triple negative breast cancer ("TNBC") patients, following standard of care.

As used in this Quarterly Report on Form 10-Q, the words the "Company," and "SELLAS" refer to SELLAS Life Sciences Group, Inc. and its consolidated subsidiaries following the completion of the business combination with Galena Biopharma, Inc., a Delaware corporation ("Galena"), and SELLAS Life Sciences Group, Ltd., a privately held Bermuda exempted company ("Private SELLAS"), in December 2017. This business combination is referred to as the Merger. Upon completion of the Merger, the Company's name changed from "Galena Biopharma, Inc." to "SELLAS Life Sciences Group, Inc." and the Company's financial statements became those of Private SELLAS.

On March 11, 2020, the World Health Organization declared the outbreak of a new coronavirus to be a “pandemic”. The COVID-19 pandemic continues to present substantial public health and economic challenges around the world which have impacted, and will continue to impact, millions of individuals and businesses worldwide. Efforts to contain the spread of the coronavirus since March 2020 have led to travel bans and restrictions, quarantines, shelter-in-place orders and shutdowns. The Company is continuously monitoring the impact of the pandemic on its clinical development programs. The full extent to which the COVID-19 pandemic directly or indirectly impacts the Company's business, results of operations and financial condition will depend on future developments that are highly uncertain, subject to change and cannot be predicted with confidence, including the actions taken to contain or treat COVID-19, the ultimate overall duration of the pandemic, the emergence of new variants of COVID-19, the emergence of new geographic hotspots where the coronavirus is spreading more rapidly, and continued or new travel restrictions, quarantines, social distancing and business closure requirements in the United States and in other countries, as well as the effectiveness of actions taken globally to contain and treat the coronavirus, including the availability of safe and effective vaccines and the uptake thereof and whether existing vaccines are effective with respect to new variants. In particular, the continued spread of the coronavirus globally could adversely impact the Company's clinical trial operations and could have an adverse impact on our business and the financial results.

2. Liquidity

Since inception, the Company has incurred recurring losses and negative cash flows from operations and, as of September 30, 2021, has an accumulated deficit of $132.0 million. During the nine months ended September 30, 2021, the Company used $21.0 million of cash in operations which included a net loss of $14.1 million, a $2.2 million increase in prepaid expenses and other assets primarily for insurance and prepaid clinical trial costs, a $5.6 million decrease in deferred revenue due to the recognition of licensing revenues and a $1.4 million decrease in accounts payable and accrued expenses and other current liabilities, partially offset by a $1.1 million decrease of contract acquisition costs related to the out-licensing of intellectual property rights and transfer of technical know-how and various net non-cash charges of $1.2 million. The Company expects to continue to generate operating losses and negative cash flows from operations for the next few years and will need additional funding to support its planned operating activities through profitability. The transition to profitability is dependent upon the successful development, approval, and commercialization of the Company's product candidates and the achievement of a level of revenues adequate to support its cost structure.

On April 16, 2021, the Company entered into a Controlled Equity OfferingSM Sales Agreement (the "Sales Agreement") with Cantor Fitzgerald & Co. (the "Agent"). From time to time during the term of the Sales Agreement, the Company may offer and sell shares of common stock having an aggregate offering price up to a total of $50.0 million in gross proceeds. The Agent will collect a fee equal to 3% of the gross sales price of all shares of common stock sold. Shares of common stock sold under the Sales Agreement are offered and sold pursuant to the Company's registration statement on Form S-3, which was filed with the SEC on April 16, 2021 and declared effective on April 29, 2021. During the nine months ended September 30, 2021, the Company sold 786,927 shares of common stock pursuant to the Sales Agreement at an average price of $12.04 per share for aggregate net proceeds of approximately $9.0 million. There were no sales of shares of common stock under the Sales Agreement during the three months ended September 30, 2021. Other than the Sales Agreement, the Company currently does not have any commitments to obtain additional funds.

The Company received $2.0 million during the nine months ended September 30, 2021 for the achievement of certain development milestones pursuant to the Company's Exclusive License Agreement (the "3DMed License Agreement) with 3D Medicines Inc. ("3DMed"). An additional $192.5 million in potential future certain development, regulatory, and sales milestones remains under the 3DMed License Agreement, which milestones are variable in nature and not under the Company's control.

As of September 30, 2021, the Company had cash and cash equivalents of approximately $26.3 million and restricted cash and cash equivalents of $0.1 million. In accordance with Accounting Standards Codification ("ASC") 205-40, Presentation of Financial Statements - Going Concern, the Company evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the consolidated financial statements are issued. The Company expects that its cash and cash equivalents, together with access to the Sales Agreement to sell common stock, will be sufficient to fund current planned operations for at least the next 12 months from the date of issuance of these financial statements, though it may pursue additional capital resources through public or private equity or debt financings or by entering into additional license agreements or collaborations with other companies. Management's expectations with respect to its ability to fund current planned operations is based on estimates that are subject to risks and uncertainties. If actual results are different from management's estimates, the Company may need to seek additional strategic or financing opportunities sooner than would otherwise be expected. There is no guarantee that any of these strategic or financing opportunities will be executed or executed on favorable terms, and some could be dilutive to existing stockholders. If the Company is unable to obtain additional funding on a timely basis, it may be forced to significantly curtail, delay, or discontinue one or more of its planned research and development programs or be unable to expand its operations or otherwise prepare for the potential regulatory approval and commercialization of its product candidates, assuming positive data.

3. Basis of Presentation and Significant Accounting Policies

The Company's complete summary of significant accounting policies can be found in "Item 8. Financial Statements and Supplementary Data - Note 3. Basis of Presentation and Significant Accounting Policies" in the audited annual consolidated financial statements included in the 2020 Annual Report. The significant accounting policies summarized and included in the 2020 Annual Report have not materially changed, except as set forth below.

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”). Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP as found in the ASC and Accounting Standards Updates of the Financial Accounting Standards Board ("FASB").

Principles of Consolidation

The consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation. Unless the context otherwise indicates, reference in these notes to the "Company" refer to SELLAS Life Sciences Group, Inc., and its wholly owned subsidiaries, Private SELLAS, SLSG Limited, LLC, Sellas Life Sciences Limited, and Apthera, Inc.

Unaudited Interim Results

These consolidated financial statements and accompanying notes should be read in conjunction with the Company's annual consolidated financial statements and the notes thereto included in the 2020 Annual Report. The accompanying consolidated financial statements as of September 30, 2021 and for the three and nine months ended September 30, 2021 and 2020, are unaudited, but include all adjustments, consisting of normal recurring entries, that management believes to be necessary for a fair presentation of the periods presented. Interim results are not necessarily indicative of results for a full year. Balance sheet amounts as of December 31, 2020 have been derived from the audited financial statements as of that date.

Reclassification

Certain prior year amounts have been reclassified to conform to current year presentation. These reclassifications had no effect on the Company's loss from operations, net loss, and net loss per share.

Time-Vested Restricted Stock Units

During the nine months ended September 30, 2021, the Board of Directors granted restricted stock units ("RSUs") to employees that vest based on continuous service. Time-vested RSUs awarded to employees vest one-fourth per year annually over four years, provided the employee remains employed with the Company. The fair values of the RSUs are measured on the date of grant and are based on the Company's closing stock price on such date. Compensation expense for RSUs with only service conditions is recognized straight-line over the applicable service period. The Company accounts for forfeitures of RSUs when they occur. Previously recognized compensation expense for forfeited RSUs are reversed in the period the RSUs are forfeited.

Net Loss Per Share

Net loss per share is computed by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted loss per share includes the effect, if any, from the potential exercise or conversion of securities, such as warrants, stock options and unvested restricted stock that would result in the issuance of incremental shares of common stock. In computing the basic and diluted net loss per share, the weighted average number of shares remains the same for both calculations due to the fact that, when a net loss exists, dilutive shares are not included in the calculation as the impact is anti-dilutive.

The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted average shares outstanding, as they would be anti-dilutive (in thousands):

Recent Accounting Standards Adopted

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes which, among other things, eliminates certain exceptions in the current rules regarding the approach for intra-period tax allocations and the methodology for calculating income taxes in an interim period, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The standard was adopted by the Company on January 1, 2021. This new standard did not have a material impact on the Company’s financial statements.

Recent Accounting Standards Not Yet Adopted

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity which, among other things, simplifies the accounting models for the allocation of proceeds attributable to the issuance of a convertible debt instrument. As a result, after adopting the ASU’s guidance, entities will not separately present in equity an embedded conversion feature in such debt. Instead, they will account for a convertible debt instrument wholly as debt, and for convertible preferred stock wholly as preferred stock (i.e., as a single unit of account), unless (i) a convertible instrument contains features that require bifurcation as a derivative under ASC 815 or (ii) a convertible debt instrument was issued at a substantial premium. The standard becomes effective for the Company in the first quarter of 2022 and early adoption is permitted. The Company is currently evaluating the potential impact of the adoption of this standard on its consolidated financial statements.

The fair value of the contingent consideration is measured at the end of each reporting period using Level 3 inputs in a probability-weighted, discounted cash-outflow model. The contingent consideration relates to Galena's acquisition of Apthera, Inc. in 2011 and the future contingent payments of up to $32.0 million based on the achievement of certain development and commercial milestones relating to the Company’s NPS product candidate, of which $2.0 million has been paid to date. The remaining contingent consideration of up to $30.0 million is payable at the election of the Company in either cash or shares of common stock, provided that the Company may not issue any shares in satisfaction of any contingent consideration, unless it has first obtained approval from its stockholders in accordance with Rule 5635(a) of the Nasdaq Marketplace Rules.

The significant unobservable assumptions include the probability of achieving each milestone, the date the Company expects to reach the milestone, and a determination of present value factors used to discount future expected cash outflows. Changes in fair value reflect new information about the probability and anticipated timing of meeting the conditions of the milestone payments. In the absence of new information, changes in fair value will only reflect the interest component of contingent consideration related to the passage of time. As of September 30, 2021, estimated future contingent milestone payments related to the Company's business range from zero, if no milestone events are achieved, to a maximum of $30.0 million if all development and commercial milestones are reached. As of September 30, 2021, resulting probability-weighted cash flows were discounted using a weighted average cost of capital of 11.8% for development milestones and cost of debt of 5.4% for the commercial milestones. The Company estimates the timing of achievement of these development milestones to range from five to eight years as of September 30, 2021.

Legal Proceedings

From time to time, the Company is subject to various pending or threatened legal actions and proceedings, including those that arise in the ordinary course of its business, which may include employment matters, breach of contract disputes and stockholder litigation. Such actions and proceedings are subject to many uncertainties and to outcomes that are not predictable with assurance and that may not be known for extended periods of time. The Company records a liability in its consolidated financial statements for costs related to claims, including future legal costs, settlements and judgments, when the Company has assessed that a loss is probable and an amount can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when no amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if there is a reasonable possibility that a material loss may have been incurred. In the opinion of management, as of the date hereof, the amount of liability, if any, with respect to these matters, individually or in the aggregate, will not materially affect the Company’s consolidated results of operations, financial position or cash flows.

The Company’s predecessor company, Galena, was involved in multiple legal proceedings and administrative actions, including stockholder class actions, both state and federal. The remaining legal proceedings to which the Company is now subject are as follows:

On February 13, 2017, certain putative shareholder securities class action complaints were filed in federal court alleging, among other things, that Galena and certain of Galena's former officers and directors failed to disclose that Galena’s promotional practices for Abstral® (fentanyl sublingual tablets) were allegedly improper and that Galena may be subject to civil and criminal liability, and that these alleged failures rendered Galena’s statements about its business misleading. The actions were consolidated, lead plaintiffs were named by the U.S. District Court for the District of New Jersey and a consolidated complaint was filed. The Company filed a motion to dismiss the consolidated complaint. On August 21, 2018, the Company's motion to dismiss the consolidated complaint was granted without prejudice to file an amended complaint. On September 20, 2018, the plaintiffs filed an amended complaint. On October 22, 2018, the Company filed a motion to dismiss the amended complaint. On November 13, 2019, the U.S. District Court for the District of New Jersey granted the Company's motion to dismiss without prejudice to file an amended complaint. On December 20, 2019, the lead plaintiffs filed a second Amended Consolidated Class Action Complaint. On January 29, 2020, the Company filed a motion to dismiss the amended complaint. On January 5, 2021, the U.S. District Court for the District of New Jersey granted the Company's motion to dismiss without prejudice to file an amended complaint. On February 18, 2021, the lead plaintiffs filed a third Amended Consolidated Class Action Complaint. The Company has reached a settlement with the plaintiffs in this action which has received preliminary court approval, with the Settlement Fairness Hearing scheduled for February 22, 2022, and which will be fully covered by the Company's directors and officers insurance policy applicable to this case.

In March 2017, a derivative complaint was filed in the U.S. District Court for the District of New Jersey against the Company’s former directors and Galena, as a nominal defendant. In July 2017, a derivative complaint was filed in California state court against the Company’s former directors and Galena, as a nominal defendant. In January 2018, a derivative complaint was filed in the U.S. District Court for the District of New Jersey against the Company’s former directors, officers and employees, and the Company as a nominal defendant. These complaints purport to assert derivative claims for breach of fiduciary duty on the Company’s behalf against the Company’s former directors and, in certain of the complaints, the Company’s current directors, and the Company’s former officers and former employees, based on substantially similar facts as alleged in the putative shareholder securities class action complaints mentioned above. The derivative lawsuit filed in California state court is currently stayed pending resolution of a motion to dismiss in the referenced securities class action. On July 13, 2020 and July 16, 2020, respectively, the Company filed motions to dismiss the two complaints filed in the U.S. District Court for the District of New Jersey. The Company has reached a settlement with the plaintiffs in these three cases which has received preliminary court approval, with the final settlement approval hearing scheduled for November 19, 2021, and which will be fully covered by the Company's directors and officers insurance policy applicable to these cases.

Warrants Classified as Liabilities

Liability-classified warrants consist of warrants to acquire common stock issued in connection with certain previous equity financings. These warrants may be settled in cash and were determined not to be indexed to the Company’s common stock.

The estimated fair value of outstanding warrants accounted for as liabilities is determined at each balance sheet date. Any decrease or increase in the estimated fair value of the warrant liability since the most recent balance sheet date is recorded in the consolidated statement of operations as change in fair value of warrant liability. The fair value of the warrants is estimated using a Black-Scholes pricing model with the following inputs:

September 30, 2021December 31, 2020
Risk free interest rate0.28 %0.16 %
Volatility138.53 %150.38 %
Expected term (years)2.002.75
Expected dividend yield— %— %

The expected volatility assumptions are based on the Company's implied volatility in combination with the implied volatilities of similar publicly traded entities. The expected life assumption is based on the remaining contractual terms of the warrants. The risk-free rate is based on the zero coupon rates in effect at the time of valuation. The dividend yield used in the pricing model is zero, because the Company has no present intention to pay cash dividends.

The changes in fair value of the warrant liability for the nine months ended September 30, 2021 were as follows (in thousands):
 
Warrant liability, December 31, 2020$55

9. License Revenue with 3D Medicines Inc.

Exclusive License Agreement with 3D Medicines Inc.

In December 2020, the Company, together with its wholly-owned subsidiary, SLSG Limited, LLC, entered into an Exclusive License Agreement (the “3DMed License Agreement”) with 3D Medicines Inc. ("3DMed"), pursuant to which the Company granted 3DMed a sublicensable, royalty-bearing license, under certain intellectual property owned or controlled by the Company, to develop, manufacture and have manufactured, and commercialize GPS and heptavalent GPS (referred to as GPS Plus) product candidates ("GPS Licensed Products") for all therapeutic and other diagnostic uses in mainland China, Hong Kong, Macau and Taiwan ("3DMed Territory"). The license is exclusive, except with respect to certain know-how that has been non-exclusively licensed to the Company and is sublicensed to 3DMed on a non-exclusive basis. The Company has retained development, manufacturing and commercialization rights with respect to the GPS Licensed Products in the rest of the world.

In partial consideration for the rights granted by the Company, 3DMed agreed to pay the Company (i) a one-time upfront cash payment of $7.5 million, and (ii) milestone payments totaling up to $194.5 million in the aggregate upon the achievement of certain technology transfer, development and regulatory milestones, as well as sales milestones based on certain net sales thresholds of GPS Licensed Products in the 3DMed Territory in a given calendar year. The Company is responsible for providing the licensed technology and data (the "3DMed License") as well as transferring certain technological and manufacturing know-how (the "transfer of know-how").

3DMed also agreed to pay tiered royalties based upon a percentage of annual net sales of GPS Licensed Products in the 3DMed Territory ranging from the high single digits to the low double digits. The royalties are payable on a GPS Licensed Product-by-GPS Licensed Product and region-by-region basis commencing on the first commercial sale of a GPS Licensed Product in a region and continuing until the latest of (i) the date that is 15 years from the receipt of marketing authorization for such GPS Licensed Product in such region and (ii) the date that is 10 years from the expiration of the last valid claim of a licensed patent covering or claiming such GPS Licensed Product in such region. The royalty rate is subject to reduction under certain circumstances, including when generic competition for a GPS Licensed Product exists in a particular region.

3DMed is responsible for all costs related to developing, obtaining regulatory approval of and commercializing the GPS Licensed Products in the 3DMed Territory. 3DMed is required to use commercially reasonable best efforts to develop and obtain regulatory approval for, and upon receipt of regulatory approval, commercialize the GPS Licensed Products in the 3DMed Territory. A joint steering committee has been established between 3DMed and the Company to coordinate and review the development, manufacturing and commercialization plans with respect to the GPS Licensed Products in the 3DMed Territory. The Company and 3DMed also agreed to negotiate in good faith the terms and conditions of a clinical supply agreement, a commercial supply agreement, and related quality agreements pursuant to which the Company will manufacture or have manufactured and supply 3DMed with all quantities of the GPS Licensed Products necessary for 3DMed to develop and commercialize the GPS Licensed Products in the 3DMed Territory until 3DMed has received all approvals required for 3DMed or its designated contract manufacturing organization to manufacture the GPS Licensed Products in the 3DMed Territory.

The 3DMed License Agreement will expire on a GPS Licensed Product-by-GPS Licensed Product and region-by-region basis on the date of the expiration of all of 3DMed’s payment obligations to the Company. Upon expiration of the 3DMed License Agreement, the license granted to 3DMed will become fully paid-up, perpetual and irrevocable. Either party may terminate the 3DMed License Agreement for the other party’s material breach following a cure period or upon certain insolvency events. The Company may terminate the 3DMed License Agreement if 3DMed or its affiliates or sublicensees challenge the validity or enforceability of the licensed patents. At any time following the two-year anniversary of the effective date, 3DMed has the right to terminate the 3DMed License Agreement for convenience, subject to certain requirements. 3DMed may terminate the 3DMed License Agreement upon prior notice to the Company if the grant of the license to 3DMed is prohibited or delayed for a period of time due to a change of U.S. export laws and regulations.

The 3DMed License Agreement includes customary representations and warranties, covenants and indemnification obligations for a transaction of this nature.

Revenue Recognition

The Company evaluated the 3DMed License Agreement and concluded that 3DMed was a customer and the 3DMed License Agreement should be evaluated under ASC 606. In determining the appropriate amount of revenue to be recognized under ASC 606 as the Company fulfills its obligations under the 3DMed License Agreement, the Company performs the following steps: (i) identifies the promised goods or services in the contract; (ii) determines whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measures the transaction price, including any constraints on variable consideration; (iv) allocates the transaction price to the performance obligations; and (v) recognizes revenue when (or as) the Company satisfies each performance obligation.

The Company identified the 3DMed License and the transfer of know-how to be the material promises under the 3DMed License Agreement. The Company determined that the 3DMed License and the transfer of know-how are not distinct from each other. As such, for the purposes of ASC 606, the Company determined that these two material promises, described above, should be combined into a single performance obligation.

The Company determined the initial transaction price of the single performance obligation to be $9.5 million, which included the $7.5 million upfront fee as well as $2.0 million in development milestones that are assessed to be probable of being achieved at the inception of the 3DMed License Agreement and therefore were not constrained. The Company achieved $1.0 million of these milestones in the first quarter of 2021 and achieved the remaining $1.0 million milestone in the second quarter of 2021. The Company determined that $192.5 million in future certain development, regulatory, and sales milestones to be variable consideration subject to constraint at inception. At the end of each subsequent reporting period, the Company will reevaluate the probability of achievement of the future development, regulatory, and sales milestones subject to constraint and, if necessary, will adjust its estimate of the overall transaction price. Any such adjustments will be recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.

For the sales-based royalties, the Company will recognize revenue when the related sales occur. To date, the Company has not recognized any royalty revenue resulting from any of its licensing arrangements.

Since 3DMed benefited from the combined single performance obligation relating to the 3DMed License and the transfer of know-how as the technology transfer occurred, the Company recognized the transaction price over the technology transfer period, which was finalized in the second quarter of 2021. The revenue recognized was based on an output method to measure progress, using a straight-line convention, which the Company believes reasonably approximates its efforts in satisfying the combined performance obligation. There was no license revenue recognized during the three months ended September 30, 2021, and $7.6 million of license revenue recognized during the nine months ended September 30, 2021. As of September 30, 2021, the initial transaction price of the single performance obligation of $9.5 million has been fully recognized as licensing revenue. There was no license revenue recognized during the three and nine months ended September 30, 2020.

The following table presents a summary of the activity in the Company's deferred revenue, related to the total cash payments received of $9.5 million to date under the 3DMed License, during the nine months ended September 30, 2021 (in thousands):

Cost of Contract Acquisition

The Company incurred contract acquisition costs (commissions) recorded as a contract asset amounting to approximately $1.4 million at inception of the 3DMed License Agreement which were capitalized under ASC 340-40 as incremental costs of obtaining the 3DMed License Agreement. These costs are amortized through general and administrative expense over the technology transfer period, commensurate with when the license revenue is recognized. There was no contract acquisitions expense during the three months ended September 30, 2021, and $1.1 million in contract acquisitions expense during the nine months ended September 30, 2021. There was no contract acquisitions expense during the three and nine months ended September 30, 2020.

Cost of License Revenue

There was no cost of license revenue during the three months ended September 30, 2021, and the Company incurred $0.2 million of sublicensing fees payable under its license from MSK in connection with the 3DMed License during the nine months ended September 30, 2021. There was no cost of license revenue during the three and nine months ended September 30, 2020.

10. Stock-Based Compensation

2017 Equity Incentive Plan

On December 29, 2017, the 2017 Equity Incentive Plan was approved by the stockholders of the Company, which provided for the issuance of up to a maximum of 24,204 shares of common stock underlying stock options granted prior to September 10, 2019. The 2017 Equity Incentive Plan was terminated upon the approval of the 2019 Incentive Plan subject to outstanding stock options granted under the 2017 Equity Incentive Plan that remain exercisable through maturity for the Company's employees and directors.

2019 Equity Incentive Plan

On September 10, 2019, the 2019 Equity Incentive Plan was approved by the stockholders of the Company, which currently allows for issuance of up to approximately (i) 1,191,000 shares of common stock in connection with the grant of stock-based awards, including stock options, restricted stock, restricted stock units, stock appreciation rights and other types of awards as deemed appropriate plus (ii) 2,684 shares of common stock under the 2017 Equity Incentive Plan that were forfeited back to the Company subsequent to September 10, 2019 and are available for future issuance.

The number of shares reserved for issuance under the 2019 Equity Incentive Plan will automatically increase on January 1 of each year, for a period of not more than four years, commencing on January 1, 2020 and ending on (and including) January 1, 2023, by an amount equal to the lesser of (i) 5% of the total number of shares of common stock outstanding at the end of the prior fiscal year; and (ii) an amount determined by the board of directors or authorized committee. As of September 30, 2021, approximately 457,000 shares of common stock were reserved for future grants under the 2019 Equity Incentive Plan.

The aggregate intrinsic values of outstanding and exercisable stock options at September 30, 2021 were calculated based on the closing price of the Company’s common stock as reported on the Nasdaq Capital Market on September 30, 2021 of $9.16 per share. The aggregate intrinsic value equals the positive difference between the closing fair market value of the Company’s common stock and the exercise price of the underlying stock options.


The following table summarizes the components of stock-based compensation expense in the consolidated statements of operations for the three and nine months ended September 30, 2021 and 2020, respectively (in thousands):

Total stock-based compensation $275 $146 $723 $437 

The Company uses the Black-Scholes option-pricing model to determine the fair value of all its stock options granted. The weighted average assumptions used during the nine months ended September 30, 2021 and 2020, respectively, were as follows:
Nine Months Ended September 30,
20212020
Risk free interest rate1.04 %0.62 %
Volatility121.29 %106.24 %
Expected lives (years)6.186.15
Expected dividend yield— %— %

There were no options granted during the three months ended September 30, 2020. The weighted-average grant date fair value of options granted during the three months ended September 30, 2021 was $8.09. The weighted-average grant date fair value of options granted during the nine months ended September 30, 2021 and 2020 was $6.99 and $1.53, respectively.

The Company’s expected common stock price volatility assumption is based upon the Company's own implied volatility in combination with the implied volatility of a basket of comparable companies. The expected life assumptions for employee grants were based upon the simplified method, which averages the contractual term of the Company’s options of ten years with the average vesting term of four years for an average of approximately six years. The expected life assumptions for non-employees were based upon the contractual term of the option. The dividend yield assumption is zero because the Company has never paid cash dividends and presently has no intention to do so. The risk-free interest rate used for each grant was also based upon prevailing short-term interest rates. The Company accounts for forfeitures as they occur.

As of September 30, 2021, there was $2.2 million of unrecognized compensation cost related to outstanding stock options that is expected to be recognized as a component of the Company’s operating expenses over a weighted-average period of 2.82 years.

2021 Employee Stock Purchase Plan

On April 22, 2021, the Board of Directors adopted the 2021 Employee Stock Purchase Plan ("2021 ESPP") which was approved by the Company's stockholders on June 8, 2021. The 2021 ESPP allows employees to contribute up to 20% of their cash earnings, subject to a maximum of $25,000 per year under Internal Revenue Service rules, to be used to purchase shares of the Company’s common stock on semi-annual purchase dates. The 2021 ESPP allows eligible employees to purchase shares of common stock at a price per share equal to 85% of the lower of the fair market value of the common stock at the beginning or end of each six-month offering period during the term of the 2021 ESPP. The first offering period began in September 2021. There are currently 300,000 shares of common stock reserved for issuance under the 2021 ESPP.

Our lead product candidate, galinpepimut-S, or GPS, is a cancer immunotherapeutic agent licensed from Memorial Sloan Kettering Cancer Center, or MSK, that targets the Wilms tumor 1, or WT1, protein, which is present in 20 or more cancer types. Based on its mechanism of action as a directly immunizing agent, GPS has potential as a monotherapy or in combination with other immunotherapeutic agents to address a broad spectrum of hematologic, or blood, cancers and solid tumor indications.

In January 2020, we commenced a Phase 3 trial, or the REGAL study, for GPS monotherapy in patients with acute myeloid leukemia, or AML, in the maintenance setting after achievement of second complete remission, or CR2, following successful completion of second-line antileukemic therapy. We expect this study will be used as the basis for submission of a Biologics License Application, or BLA, subject to a statistically significant and clinically meaningful data outcome and agreement with the U.S. Food & Drug Administration, or the FDA. We expect to enroll approximately 116 patients at up to approximately 135 clinical sites primarily in the United States and Europe.

In December 2018, we initiated a Phase 1/2 multi-arm "basket" type clinical study of GPS in combination with Merck & Co., Inc.’s anti-PD-1 therapy, pembrolizumab (Keytruda®). The tumor type currently being studied is ovarian cancer (second or third line).

In February 2020, a Phase I open-label investigator-sponsored clinical trial of GPS, in combination with Bristol-Myers Squibb’s anti-PD-1 therapy, nivolumab (Opdivo®), in patients with malignant pleural mesothelioma, or MPM, who harbor relapsed or refractory disease after having received frontline standard of care multimodality therapy (the "MPM IST") was commenced at MSK.

GPS was granted Orphan Drug Product Designations from the FDA, as well as Orphan Medicinal Product Designations from the European Medicines Agency, or EMA, for GPS in AML, MPM and multiple myeloma, or MM, as well as Fast Track Designation for AML, MPM, and MM from the FDA.

Nelipepimut-S or NPS

Nelipepimut-S, or NPS, is a cancer immunotherapy targeting the human epidermal growth factor receptor 2, or HER2, expressing cancers. Data presented in 2018 from a Phase 2b clinical trial of the combination of trastuzumab (Herceptin®) plus NPS in HER2 low expressing (1+ or 2+ per immunohistochemistry, or IHC) breast cancer patients in the adjuvant setting to prevent recurrences showed a clinically and statistically significant improvement in the disease-free survival, or DFS, rate for the triple negative breast cancer, or TNBC, cohort at 24 months for patients treated with NPS plus trastuzumab of 92.6% compared to 70.2% for those treated with trastuzumab alone. Following ongoing discussions with the FDA and based upon written feedback from the FDA and on the totality of clinical, safety and translational NPS data to date, we have finalized the design and plan for a Phase 3 registration-enabling study of NPS in combination with trastuzumab for the treatment of patients with TNBC in the adjuvant setting after standard treatment. If successful, we believe this study may be considered as the basis for a BLA submission to the FDA. We are seeking out-licensing opportunities to fund and conduct the future clinical development of NPS in order to maximize the potential of the program and we do not plan to conduct and fund a Phase 3 program for NPS on our own.

GPS Program Update

The final statistical analysis plan, or SAP, for the REGAL study provides for a planned interim safety and futility analysis after 80 events (deaths) which we had anticipated would take place in the first half of 2022, provided that the ongoing COVID-19 pandemic did not significantly adversely impact our projected timeline for enrollment. Over the last 12 to 18 months we have monitored the impact of the COVID-19 pandemic on our estimated timeline for the REGAL study. During this period, we took several steps to mitigate possible and actual delays due to COVID including increasing the number of clinical sites and the number of countries in which sites are located in order to maintain our original timeline. Even with such mitigation steps, we now anticipate that the interim analysis will take place in the second half of 2022, provided that the ongoing COVID-19 pandemic does not continue to significantly adversely impact our projected timeline for enrollment. In addition to the planned interim analysis under the SAP, the final charter for the Independent Data Monitoring Committee, or the IDMC, for the REGAL study provides for enrollment-based safety, futility and efficacy analyses prior to the interim analysis.

In June 2021, a peer-reviewed article was published in the journal Bone Marrow Transplantation which included a comprehensive retrospective analysis of survival outcomes in 4,280 AML patients treated in more than 450 blood and marrow transplant centers worldwide between 2007 and 2015. The analysis demonstrates the high unmet medical need to extend survival in AML patients. The published analysis showed that even among patients eligible to receive a bone marrow transplant, considered to be the only potential curative therapy in AML, less than half of the patients are alive five years after initial diagnosis. The analysis highlights the importance of the presence of minimal residual disease, or MRD, with patients who harbored MRD at the time of transplant having only 34%-37% probability of surviving five years. In our completed Phase 2 study of AML patients who achieved first remission, or CR1, OS for patients treated with GPS was 48.5 months from time of enrollment in the study. The retrospective analysis of the pooled outcomes for AML patients who underwent a transplant in the article published in Bone Marrow Transplantation indicates that the median OS from the time of transplant is approximately 26 months. In our Phase 2 AML CR1 study the median OS from the time of initial AML diagnosis was 67.6 months.

Based on our review of this data and after consultation with leading key opinion leaders for treatment of AML, we are currently in the regulatory and clinical planning stages for a potential Phase 2/3 study of GPS in AML patients who have undergone a bone marrow transplant and who harbor MRD.

In June 2021, we reported encouraging updated clinical data from the MPM IST. For the four evaluable patients, all of whom had the epithelioid and/or sarcomatoid variant and have received and progressed with, or are refractory to, frontline pemetrexed-based chemotherapy, the average overall survival, or OS, was 35.3 weeks with a median OS of 35.4 weeks at a median follow-up of 35.4 weeks. OS for relapsed/refractory patients receiving standard of care (pemetrexed, a chemotherapy) is approximately 28 weeks. Average progression-free survival, of PFS, was 8.8 weeks with a median PFS of seven weeks at a median follow-up of 35.4 weeks. The safety profile of the GPS-nivolumab combination was similar to that seen with nivolumab alone, with the addition of only low-grade, temporary local reactions at the GPS injection site which was consistent with previous clinical studies of GPS.


23


In June 2021, we also reported updated clinical data and immune response profiles from the basket study of GPS in combination with pembrolizumab for treating WT1+ advanced ovarian cancer. Of the 11 evaluable patients, 66.7% were refractory to or had failed their second-line therapies and 33.3% had failed third-line or later therapy and all patients were resistant to the standard of care platinum-based therapy. The expected overall survival for patients receiving standard of care platinum-based therapy is nine to 12 months. The median OS among the patients in this trial is not yet known as all patients remained alive at the time of analysis which time period exceeds nine months. In an ad hoc analysis of the clinical outcomes for the cohort of 11 patients, the disease control rate, or DCR, which is the sum of overall response rate and rate of stable disease, was 63.6% with a median follow-up of 15.4 weeks. At the time of follow-up analysis, median PFS was 11.8 weeks. The safety profile of the GPS-pembrolizumab combination was similar to that seen with pembrolizumab alone, with the addition of only low-grade, temporary local reactions at the GPS injection site, consistent with previously performed clinical studies with GPS. We also reported immunobiological data from this study. CD8+ and CD4+ T-lymphocytes were isolated from peripheral blood mononuclear cells from three patients from whom samples had been collected both at baseline and at the time of the sixth GPS dose (i.e., 18 weeks after starting investigational therapy). The T-cells were assayed ex-vivo for immune responses against the pool of the four peptides that comprise GPS using the validated assay intracellular cytokine staining with fluorescence-activated single cell sorting (ICS-FACS) (Scorpion Biological Services, San Antonio, Texas), with appropriate positive and negative controls. A total of five cytokine “channels” were used for the analysis (i.e., interferon-g, TNF-a, interleukin-2, CD107a and MIP-1b). The peptide re-challenge incubation period was seven days. At the 18-week time point versus pre-vaccination baseline, the assay demonstrated a relative increase in WT1-specific T-lymphocyte frequencies in peripheral blood averaging +242% (range: +104 to +385% across five cytokines) for CD8+ and +80.5% (range: +1 to +174%) for CD4+. There was also evidence of polyfunctional T-cell activation (increases in secretion of >2 cytokines) in two out of three patients (66%).

Impact of COVID-19

On March 11, 2020, the World Health Organization declared the outbreak of a new coronavirus to be a “pandemic”. The COVID-19 pandemic continues to present substantial public health and economic challenges around the world which have impacted, and will continue to impact, millions of individuals and businesses worldwide. Efforts to contain the spread of the coronavirus since March 2020 have led to travel bans and restrictions, quarantines, shelter-in-place orders and shutdowns. As we have historically functioned operationally as a semi-virtual company, the transition to “work-from-home” for our employees has not materially altered our business operations. We have implemented a return-to-work policy in compliance with federal, state and local requirements and guidance, which provides for a hybrid of remote and in-office work, and we have operated on such a semi-virtual basis during the first nine months of 2021. We are continuously monitoring the impact of the pandemic on our clinical development programs. Our Phase 3 REGAL study is progressing, with the necessary work to activate additional sites in the United States and Europe continuing. However, throughout the pandemic we have observed that clinical site initiations and patient enrollment have taken more time than what had been projected prior to the start of the pandemic, likely due to prioritization of hospital resources towards the COVID-19 pandemic, quarantines which have impeded patient movement or interrupted operations at sites, and other COVID-related reasons. Accordingly, due to the accumulation of these delays over the past 18 months, we have adjusted the projected timing of the REGAL study. We believe that the COVID-19 pandemic has not materially impacted our efforts to out-license NPS. The full extent to which the COVID-19 pandemic will continue to directly or indirectly impact our business, results of operations and financial condition will depend on future developments that are highly uncertain, subject to change and cannot be predicted with confidence, including the actions taken to contain or treat COVID-19, the ultimate overall duration of the pandemic, the emergence of new variants of COVID-19, the emergence of new geographic hotspots where the coronavirus is spreading more rapidly, and continued or new travel restrictions, quarantines, social distancing and business closure requirements in the United States and in other countries, as well as the effectiveness of actions taken globally to contain and treat the coronavirus, including the availability of safe and effective vaccines and the uptake thereof and whether existing vaccines are effective with respect to new variants. In particular, the continued spread of the coronavirus globally could adversely impact our clinical trial operations and could have an adverse impact on our business and the financial results.

Components of Results of Operations

License Revenue

License revenue consists of revenue recognized pursuant to our Exclusive License Agreement with 3D Medicines Inc., or 3DMed, dated December 7, 2020, or the 3DMed License Agreement. In the future, we may generate revenue from a combination of reimbursements, up-front payments, milestone payments and royalties in connection with the 3DMed License Agreement.

Cost of License Revenue

Cost of license revenue consists of sublicensing fees payable under our license from MSK in connection with the 3DMed License Agreement.

Research and Development Expense

Research and development expense consists of expenses incurred in connection with the discovery and development of our product candidates. We expense research and development costs as incurred. These expenses include:
expenses incurred under agreements with CROs, as well as investigative sites and consultants that conduct our preclinical studies and clinical trials;
manufacturing expenses;
quality control and quality assurance services;
outsourced professional scientific development services;
employee-related expenses, which include salaries, benefits and stock-based compensation;
payments made under our license agreements, under which we acquired certain intellectual property;
expenses relating to certain regulatory activities, including filing fees paid to regulatory agencies;
laboratory materials and supplies used to support our research activities; and
allocated expenses, utilities and other facility-related costs.
 
The successful development of our current and future product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of, or when, if ever, material net cash inflows may commence from any current or future product candidates. This uncertainty is due to the numerous risks and uncertainties associated with the duration and cost of our clinical trials, which vary significantly over the life of a project as a result of many factors, including, but not limited to:
the number of clinical sites included in the trials;
the length of time required to enroll suitable patients;
the number of patients that ultimately participate in the trials;
the number of doses patients receive;
the duration of patient follow-up;
the results of clinical trials;
the expenses associated with manufacturing;
the receipt of marketing approvals;
the commercialization of current and future product candidates; and
the impact of the COVID-19 pandemic.


25


Research and development activities are central to our business model. Cancer immunotherapy product candidates in the later stages of clinical development generally have higher development costs than those in the earlier stages of clinical development, primarily due to the increased size and duration of the later-stage clinical trials. We expect our research and development expenses to increase for the foreseeable future as we conduct and complete our ongoing early and late stage clinical trials and initiate additional clinical trials.

Our expenditures are subject to additional uncertainties, including the terms and timing of regulatory approvals. We may never succeed in achieving regulatory approval for any of our current or future product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some product candidates or target indications or focus on others. A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or other regulatory authorities were to require us to conduct clinical trials beyond those that we currently anticipate, or if we experience significant delays in enrollment in any of our clinical trials due to the COVID-19 pandemic or otherwise, we could be required to expend significant additional financial resources and time on the completion of clinical development. Cancer immunotherapy product commercialization may take several years and millions of dollars in development costs.

General and Administrative Expense

General and administrative expenses consist principally of salaries and related costs for personnel in executive, administrative, finance and legal functions, including stock-based compensation, travel expenses and recruiting expenses, fees for outside legal counsel, amortization of contract acquisition costs (commissions), and director and officer insurance premiums. Other general and administrative expenses include facility related costs, patent filing and prosecution costs, professional fees for business development, accounting, consulting, legal and tax-related services associated with maintaining compliance with our Nasdaq listing and SEC reporting requirements, investor relations costs, and other expenses associated with being a public company.

If and when we believe that regulatory approval of a product candidate appears likely, we anticipate that an increase in general and administrative expenses will occur as a result of our preparation for commercial operations, particularly as it relates to the sales and marketing of such product candidate. Cancer immunotherapy product commercialization may take several years and millions of dollars in development costs.

Non-Operating (Expense) Income, Net

Non-operating (expense) income, net consists of changes in fair value of our warrant liability, changes in fair value of our contingent consideration, and interest income. Interest income primarily reflects interest earned from our cash and cash equivalents.

Critical Accounting Policies and Estimates

In the 2020 Annual Report, we disclosed our critical accounting policies and estimates upon which our financial statements are derived. There have been no material changes to these policies since December 31, 2020 that are not included in Note 3 of the accompanying consolidated financial statements for the nine months ended September 30, 2021. Readers are encouraged to read the 2020 Annual Report in conjunction with this Quarterly Report on Form 10-Q.

Further analysis of the changes and trends in our operating results are discussed below.

Licensing Revenue

Licensing revenue was $7.6 million for the nine months ended September 30, 2021 and was related to the out-licensing of intellectual property rights and transfer of technical know-how associated with the 3DMed License Agreement for the development and commercialization of GPS in China, Hong Kong, Macau, and Taiwan. There was no licensing revenue for the nine months ended September 30, 2020.

Cost of License Revenue

We incurred $0.2 million of sublicensing fees payable under our license from MSK in connection with the 3DMed License Agreement during the nine months ended September 30, 2021. There was no cost of license revenue for the nine months ended September 30, 2020.


27


Research and Development
Research and development expenses were $4.5 million for the three months ended September 30, 2021 compared to $2.4 million for the three months ended September 30, 2020. The $2.1 million increase was primarily attributable to a $1.7 million increase in clinical trial expenses primarily related to our ongoing Phase 3 REGAL clinical trial of GPS in AML, a $0.8 million increase in manufacturing and drug supply costs due to the ramp up of the manufacture of clinical trial materials and registration batches of GPS, and a $0.1 million increase in personnel related expenses due to increased headcount. These increases were partially offset by a $0.2 million decrease in licensing fees and a $0.3 million decrease in other research and development expenses. We anticipate that our research and development expenses will increase in the future as we continue to advance the development of GPS, including our Phase 3 trial of GPS in AML and the ongoing basket trial of GPS in combination with pembrolizumab.

Research and development expenses were $12.3 million for the nine months ended September 30, 2021 compared to $6.5 million for the nine months ended September 30, 2020. The $5.8 million increase was primarily attributable to a $3.2 million increase in clinical trial expenses primarily related to our Phase 3 REGAL clinical trial of GPS in AML, a $2.5 million increase in manufacturing and drug supply costs due to the ramp up of the manufacture of clinical trial materials and registration batches of GPS, a technology transfer to a new contract manufacturer, and clinical drug supply purchase costs in the European Union as we open sites and enroll patients in European Union countries for our Phase 3 REGAL clinical trial for GPS in AML, and a $0.4 million increase in personnel related expenses due to increased headcount. These increases were partially offset by a $0.4 million decrease in licensing fees, and a $0.1 million decrease in other research and development expenses.

General and Administrative

General and administrative expenses were $2.4 million for the three months ended September 30, 2021 compared to $2.1 million for the three months ended September 30, 2020. The $0.3 million increase was primarily due to a $0.3 million increase in personnel related expenses due to increased headcount, a $0.1 million increase in outside services and public company costs, and a $0.1 million increase in professional services. These increases were partially offset by a $0.2 million decrease in other general and administrative related expenses.

General and administrative expenses were $8.8 million for the nine months ended September 30, 2021 compared to $6.3 million for the nine months ended September 30, 2020. The $2.5 million increase was primarily due to a $1.1 million amortization expense of our contract asset associated with the 3DMed License Agreement, a $0.6 million increase in personnel related expenses due to a $0.2 million increase in non-cash stock-based compensation and increased headcount, as well as a $0.7 million increase in legal fees as compared to the first nine months of 2020 in which we received a credit in legal fees that offset a significant amount of legal expenses incurred for that period, and a $0.1 million increase in other general and administrative related expenses.

Non-Operating Income (Expense), Net

Non-operating income (expense), net for the three and nine months ended September 30, 2021 and 2020, respectively, was as follows (in thousands):
Three Months Ended September 30,Nine Months Ended September 30,
20212020Change20212020Change
Change in fair value of warrant liability$30 $$24 $(29)$25 $(54)

Interest income— 25 (19)
Total non-operating income (expense), net$(108)$19 $(127)$(426)$(218)$(208)

Net non-operating expense of $0.1 million for the three months ended September 30, 2021 was primarily due to the increase in the change in the fair value of the contingent consideration liability partially offset by a slight decrease in the change in the fair value of the warrant liability. The change in the fair value of the contingent consideration liability reflects the interest component of contingent consideration related to the passage of time. The decrease in the estimated fair value of our warrant liability was primarily due to a decrease in our common stock price. Interest income consisted of interest earned from our cash and cash equivalents.

Net non-operating income was nominal for the three months ended September 30, 2020.

Net non-operating expense of $0.4 million during the nine months ended September 30, 2021 was primarily due to the increase in the change in the fair value of the contingent consideration liability and a slight increase in the change in the fair value of the warrant liability partially offset by nominal interest income. The change in the fair value of the contingent consideration liability reflects the interest component of contingent consideration related to the passage of time. The increase in the estimated fair value of our warrant liability was primarily due to an increase in our common stock price. Interest income consisted of interest earned from our cash and cash equivalents.

Net non-operating expense of $0.2 million during the nine months ended September 30, 2020 was primarily due to the increase in the change in the fair value of the contingent consideration liability partially offset by a slight decrease in the change of the fair value of the warrant liability and nominal interest income. The change in the fair value of contingent consideration liability reflect the interest component of contingent consideration related to the passage of time. The decrease in the estimated fair value of our warrant liability was primarily due to a decrease in our common stock price.

The change in fair value of warrant liability and change in fair value of contingent consideration are non-cash in nature.

Income Tax Expense

There was no income tax expense for the three and nine months ended September 30, 2021 and 2020. We continue to maintain a full valuation allowance against our net deferred tax assets.

Liquidity and Capital Resources

We did not generate any revenue from product sales during the three and nine months ended September 30, 2021 and 2020. Through September 30, 2021, the Company has only generated licensing revenue from the 3DMed License Agreement. Since inception, we have incurred net losses, used net cash in our operations, and have funded substantially all of our operations through proceeds of the sale of equity securities and convertible notes.

On April 16, 2021, we entered into a Controlled Equity OfferingSM Sales Agreement, or Sales Agreement, with Cantor Fitzgerald & Co., or the "Agent. From time to time during the term of the Sales Agreement, we may offer and sell shares of common stock having an aggregate offering price up to a total of $50.0 million in gross proceeds. The Agent will collect a fee equal to 3% of the gross sales price of all shares of common stock sold. Shares of common stock sold under the Sales Agreement will be offered and sold pursuant to our registration statement on Form S-3, which was filed with the SEC on April 16, 2021 and was declared effective on April 29, 2021. During the nine months ended September 30, 2021 we sold 786,927 shares of our common stock pursuant to the Sales Agreement at an average price of $12.04 per share for aggregate net proceeds of approximately $9.0 million. We did not sell shares of common stock under the Sales Agreement during the three months ended September 30, 2021. Other than the Sales Agreement, we do not have any commitments to obtain additional funds.

We received $2.0 million during the nine months ended September 30, 2021 for the achievement of certain development milestones pursuant to our 3DMed License Agreement. An additional $192.5 million in potential future certain development, regulatory, and sales milestones remains under the 3DMed License Agreement which milestones are variable in nature and not under our control.

As of September 30, 2021, we had an accumulated deficit of $132.0 million, cash and cash equivalents of $26.3 million and restricted cash and cash equivalents of $0.1 million. In addition, we had current liabilities of $5.3 million as of September 30, 2021. We expect that our cash and cash equivalents, together with our access to the Sales Agreement, will be sufficient to fund current planned operations for at least the next twelve months from the date of issuance of these financial statements, although we may pursue additional capital resources through public or private equity or debt financings or by establishing additional collaborations with other companies. Our expectations with respect to our ability to fund current planned operations is based on estimates that are subject to risks and uncertainties. If actual results are different from management's estimates, we may need to seek additional strategic or financing opportunities sooner than would otherwise be expected. There is no guarantee that any of these strategic or financing opportunities will be executed or executed on favorable terms, and some could be dilutive to existing stockholders. If we are unable to obtain additional funding on a timely basis, we may be forced to significantly curtail, delay, or discontinue one or more of our planned research and development programs or be unable to expand our operations or otherwise prepare for the potential regulatory approval and commercialization of our product candidates, assuming positive data.

Our future operations are highly dependent on a combination of factors, including (i) the timely and successful completion of any additional financings, (ii) our ability to complete revenue-generating partnerships with pharmaceutical and biotechnology companies, (iii) the success of our research and development activities, (iv) the development of competitive therapies by other biotechnology and pharmaceutical companies, and, ultimately, (v) regulatory approval and market acceptance of our proposed future products.

We had no investing activities during the nine months ended September 30, 2021 and 2020.

Net Cash Used in Operating Activities

Net cash used in operating activities of $21.0 million during the nine months ended September 30, 2021 was primarily attributable to an $8.1 million change in our operating assets and liabilities and our net loss of $14.1 million, which was offset by various net non-cash charges of $1.2 million. The net change in our operating assets and liabilities of $8.1 million is primarily attributable to a decrease in deferred revenue of $5.6 million, a $2.2 million increase in prepaid expenses and other assets primarily for prepaid insurance premiums and clinical trial costs and a $1.4 million decrease in accounts payable and accrued expenses and other current liabilities, partially offset by a $1.1 million decrease in contract acquisition costs related to the out-licensing of intellectual property rights and transfer of technical know-how associated with the 3DMed License Agreement.

Net cash used in operating activities of $13.8 million during the nine months ended September 30, 2020 was primarily attributable to our net loss of $13.0 million and a $1.6 million net change in our operating assets and liabilities, which was offset by various net non-cash charges of $0.8 million. The net change in our operating assets and liabilities of $1.6 million is primarily attributable to an increase in prepaid expenses and other current assets of $0.6 million and a $1.0 million decrease in accounts payable and accrued expenses and other current liabilities.

Net Cash Provided by Financing Activities

We generated $12.0 million of net cash from financing activities for the nine months ended September 30, 2021. We received $9.0 million in net proceeds from the issuance of common stock under the Sales Agreement, as well as $3.0 million from the exercise of warrants to acquire shares of common stock.

We generated $14.8 million of net cash from financing activities for the nine months ended September 30, 2020. We received $14.5 million in aggregate net proceeds from the sale of securities in a registered direct offering in January 2020 and a PIPE transaction in July 2020 and $0.3 million from the collection of our stock subscription receivable in January 2020.

Off-Balance Sheet Arrangements

We have not entered into any off-balance sheet financing arrangements as of September 30, 2021.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, our principal executive officer and our principal financial officer (the “Certifying Officer”), evaluated the effectiveness of our disclosure controls and procedures. Disclosure controls and procedures are controls and procedures designed to reasonably assure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934 (the “Exchange Act”), such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms. Disclosure controls and procedures are also designed to reasonably assure that such information is accumulated and communicated to our management, including the Certifying Officers, as appropriate to allow timely decisions regarding required disclosure.
