NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Description of Business

Overview

SELLAS Life Sciences Group, Inc. (the "Company" or “SELLAS”) is a late-stage clinical biopharmaceutical company focused on the development of novel cancer immunotherapeutics for a broad range of indications.

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.

2. Liquidity

The Company has not generated any revenues, including from product sales, and has funded operations primarily from the proceeds of sales of its equity interests and convertible notes. Additional financing will be required by the Company to continue to fund its research and development activities. No assurance can be given that any such financing will be available when needed or that the Company’s research and development efforts will be successful.

On June 18, 2019, the Company consummated an underwritten public offering (the “June 2019 Offering”) of (i) 527,344 shares of common stock, (ii) 1,472,656 pre-funded warrants exercisable for shares of common stock, and (iii) accompanying common stock warrants to purchase up to an aggregate of 2,000,000 shares of common stock. The shares of common stock and accompanying common stock warrants were sold at a combined price of $7.50 per share and accompanying common stock warrant. Each common stock warrant sold with the shares of common stock represented the right to purchase one share of common stock at an exercise price of $25.00 per share and, commencing July 10, 2019, could be exercised pursuant to the terms thereof on a cashless basis, at the option of the holder, in whole or in part, for one share of common stock, if the weighted average price of the common stock on any trading day immediately prior to the exercise date is lower than the then-applicable exercise price per share. As of September 30, 2019, 1,997,740 of the June 2019 Offering warrants were cashlessly exercised and 2,260 warrants remain outstanding. The pre-funded warrants and accompanying common stock warrants were sold at a combined price of $7.495 per pre-funded warrant and common stock warrant. The pre-funded warrants were exercisable immediately, at an exercise price of $0.005 per share. As of September 30, 2019, all of the pre-funded warrants sold in the June 2019 Offering were exercised.

The net proceeds to the Company from the June 2019 Offering, after deducting underwriting discounts and commissions and other estimated offering expenses, and excluding the exercise of any warrants, was approximately $13.4 million. See Notes 7 and 8 for further discussion of the June 2019 Offering.

On March 6, 2019, the Company entered into a Warrant Exercise Agreement (the "Exercise Agreement") with one of the holders of the Company's warrants issued in July 2018. Pursuant to the Exercise Agreement, the warrant holder agreed to exercise for cash up to 76,000 of its warrants issued in July 2018 ("2018 Warrants") into shares of common stock at an adjusted exercise price of $55.00 per share for any 2018 Warrants exercised prior to May 31, 2019. In addition to reducing the exercise price of the 2018 Warrants, the Exercise Agreement also provided for the issuance of new warrants to purchase up to an aggregate of approximately 76,000 shares of common stock at an exercise price of $70.00 per share ("New Warrants") to be issued on a share-for-share basis in an amount equal to the number of the 2018 Warrants that were cash exercised by the warrant holder prior to May 31, 2019. During the nine months ended September 30, 2019, the warrant holder exercised approximately 63,000 2018 Warrants for gross proceeds of $3.5 million and approximately 63,000 New Warrants were issued. The Exercise Agreement expired on May 31, 2019.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - Continued

(Unaudited)

The Company regularly explores alternative means of financing its operations and seeks funding through various sources, including public and private securities offerings, collaborative arrangements with third parties and other strategic alliances and business transactions.

On October 29, 2019, the Company entered into an Equity Distribution Agreement (the "Distribution Agreement") with Maxim Group LLC (the "Agent"). From time to time during the term of the Distribution Agreement, the Company may offer and sell shares of common stock having an aggregate offering price up to a total of $5.0 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 Distribution Agreement will be offered and sold pursuant to the Company's effective registration statement on Form S-3. Subsequent to September 30, 2019, the Company sold 322,719 shares of common stock pursuant to the Distribution Agreement for net proceeds of $1.9 million.

Other than the Distribution Agreement, the Company currently does not have any commitments to obtain additional funds and may be unable to obtain sufficient funding in the future on acceptable terms, if at all. If the Company cannot obtain the necessary funding, it will need to delay, scale back or eliminate some or all of its research and development programs or enter into collaborations with third parties to commercialize potential products or technologies that it might otherwise seek to develop or commercialize independently, or cease operations. If the Company engages in collaborations, it may receive lower consideration upon commercialization of such products than if it had not entered into such arrangements or if it entered into such arrangements at later stages in the product development process.

As of September 30, 2019, the Company had cash and cash equivalents of approximately $9.1 million, and restricted cash and cash equivalents of $0.1 million. The Company has incurred recurring losses and negative cash flows from operations and has an accumulated deficit of $93.7 million as of September 30, 2019. In addition, the Company had aggregate outstanding accounts payable and accrued expenses and other current liabilities of $5.6 million as of September 30, 2019. The Company expects its cash as of September 30, 2019, together with the net proceeds received from the sale of common stock pursuant to the Distribution Agreement subsequent to September 30, 2019, will enable the Company to fund its operating expenses and capital expenditure requirements through the third quarter of 2020.

The Company has evaluated the guidance of Accounting Standards Codification ("ASC") 205-40, Presentation of Financial Statements - Going Concern, in order to determine whether there is substantial doubt about its ability to continue as a going concern for one year from the date its financial statements are available to be issued. The Company has prepared its condensed consolidated financial statements assuming that it will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred net losses since inception and it expects to generate losses from operations for the foreseeable future primarily due to research and development costs for its potential product candidates, which raises substantial doubt about the Company's ability to continue as a going concern. Various internal and external factors will affect whether and when the Company’s product candidates become approved drugs and how significant their market share will be, some of which are outside of the Company’s control. The length of time and cost of developing and commercializing these product candidates and/or the risk of failure of any such product candidates at any stage of the drug approval process will materially affect the Company’s financial condition and future operations. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

3. Basis of Presentation and Significant Accounting Policies

The Summary of Significant Accounting Policies included in the Company's 2018 Annual Report have not materially changed, except as set forth below.

Basis of Presentation

The accompanying condensed 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 Accounting Standards Codification ("ASC") and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”).

Reverse Stock Split

On November 6, 2019, the Company filed a certificate of amendment to its amended and restated Certificate of Incorporation to effect a 1 - for - 50 reverse stock split of the Company's outstanding shares of common stock which became effective on November 7, 2019. The shares of common stock underlying the Company's outstanding options and warrants were also proportionately adjusted for the reverse stock split. In addition, the number of shares of common stock available for issuance, under the Company’s equity incentive plans and employee stock purchase plan, were proportionately adjusted for the reverse stock split. Further, the per share exercise prices for options granted under such plans were proportionately adjusted for the reverse stock split. The reverse stock split reduced the number of shares of the Company’s common stock that were outstanding at November 8, 2019 from 227,800,147 to 4,549,208, after the cancellation of fractional shares. No fractional shares were issued in connection with the reverse stock split. Stockholders who otherwise held fractional shares of the Company’s common stock as a result of the reverse stock split received a cash payment in lieu of such fractional shares. These condensed consolidated financial statements give retroactive effect to such reverse stock split and all share and per share amounts have been adjusted accordingly.

Principles of Consolidation

The condensed 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, Sellas Life Sciences Group UK Ltd., and Apthera, Inc. The functional currency of the Company's non-U.S. operations is the U.S. dollar.

Unaudited Interim Results

These condensed 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 2018 Annual Report. The accompanying condensed consolidated financial statements at September 30, 2019 and for the three and nine months ended September 30, 2019 and 2018, 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, 2018 have been derived from the audited financial statements as of that date.

Cash, Cash Equivalents, Restricted Cash, and Restricted Cash Equivalents

The following table provides a reconciliation of the components of cash, cash equivalents, restricted cash, and restricted cash equivalents reported in the Company's condensed consolidated balance sheets to the total of the amount presented in the condensed consolidated statements of cash flows (in thousands):



	September 30, 2019		December 31, 2018
Cash and cash equivalents	$	9,119	$	5,337
Restricted cash and cash equivalents	115		114
Total cash, cash equivalents, restricted cash, and restricted cash equivalents	$	9,234	$	5,451

The Company maintained restricted cash and cash equivalents as of September 30, 2019 and December 31, 2018 as collateral for its corporate credit cards.

Preferred Stock

The Company applies the accounting standards for distinguishing liabilities from equity when determining the classification and measurement of its preferred stock. Preferred shares subject to mandatory redemption are classified as liability instruments and are measured at fair value. Conditionally redeemable preferred shares (including preferred shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, preferred shares are classified as stockholders’ equity.

Recent Accounting Pronouncements Adopted

In July 2019, the FASB issued Accounting Standards Update ("ASU") No. 2019-07, Codification Updates to SEC Sections - Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization and Miscellaneous Updates (SEC Update). ASU No. 2019-07 clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the SEC’s regulations, thereby eliminating redundancies and making the codification easier to apply. ASU No. 2019-07 became effective upon issuance and the adoption of ASU No. 2019-07, which is applied prospectively, did not have an impact on the Company’s consolidated financial statements and disclosures.

On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842), as amended, which supersedes the lease accounting guidance under Topic 840, and generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use ("ROU") assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. The new guidance retains a distinction between finance leases and operating leases, while requiring companies to recognize both types of leases on their balance sheet. The classification criteria for distinguishing between finance leases and operating leases are substantially similar to the criteria for distinguishing between capital leases and operating leases in legacy U.S. GAAP - ASC 840.

The Company adopted the new guidance using the modified retrospective transition approach by applying the new standard to all leases existing at the date of initial application and not restating comparative periods. The Company evaluated the potential cumulative effect of applying the new guidance and determined that such an adjustment would be immaterial. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with the Company's historical accounting under Topic 840.

(Unaudited)

Under Topic 842, the Company determines if an arrangement is a lease at inception. ROU assets and liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company's incremental borrowing rate is a hypothetical rate based on the Company's understanding of what the Company's credit rating would be. The Company's lease terms may include options to extend or terminate the lease and the related payments are only included in the lease liability when it is reasonably certain that the Company will exercise such options. In connection with the adoption, the Company did not separate lease and associated non-lease components for the transitioned leases, but instead are accounting for them together as a single component. The adoption did not change the classification of lease-related expenses in the condensed consolidated statements of operations, and the Company does not expect changes to the pattern of expense recognition. As a result, the adoption does not impact the Company's beginning retained earnings, or the Company's prior year condensed consolidated statements of operations and will not materially affect the condensed consolidated statements of cash flows.

In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity Topic (480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instrument with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception, which modifies the classification of some financial instruments. A down round feature no longer precludes equity classification, therefore a freestanding equity feature would no longer be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. For freestanding equity-classified financial instruments, the amendments require entities present earnings per share in accordance with Topic 260, and to recognize the effect of the down round feature when triggered. Convertible instruments are now subject to specialized contingent beneficial conversion features. The Company adopted ASU No. 2017-11 on January 1, 2019 and determined it did not have a material impact to its condensed consolidated financial statements. The Company determined its liability classified warrants contained cash settlement features that would continue to preclude equity classification subsequent to its adoption of ASU No. 2017-11.

Recent Accounting Pronouncements Pending Adoption

In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Accounting, which simplifies the accounting for share-based payments granted to nonemployees for goods and services. The ASU supersedes ASC 505-50 and expands the scope of ASC 718 to include all share-based payment arrangements related to the acquisition of goods and services from both nonemployees and employees. As a

result, most of the guidance in ASC 718 associated with employee share-based payments, including most of its requirements related to classification and measurement, applies to nonemployee share-based payment arrangements. ASU No. 2018-07 generally requires an entity to use a modified retrospective transition approach, with a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year, for all (1) liability-classified nonemployee awards that have not been settled as of the adoption date and (2) equity-classified nonemployee awards for which a measurement date has not been established. The guidance is applicable to public business entities for fiscal years beginning after December 15, 2019 and interim periods within those years. The Company is currently evaluating the potential impact of the adoption of this standard on its consolidated financial statements.

In August 2018, FASB issued No. ASU 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU No. 2018-13 modifies, adds and removes certain specific disclosure requirements on fair value measurements in Topic 820. The amendments in ASU 2018-13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU No. 2018-13 and to delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the potential impact of the adoption of the new standard on the consolidated financial statements.

4. Fair Value Measurements

The following tables present information about the Company's assets and liabilities measured at fair value on a recurring basis in the condensed consolidated balance sheets (in thousands):



Description	September 30, 2019		Quoted Prices In Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Unobservable Inputs (Level 3)

A reconciliation of the change in the fair value of the contingent consideration liability for the nine months ended September 30, 2019 is as follows (in thousands):



	Fair Value Measurements Using Significant Unobservable Inputs (Level 3)
Contingent consideration, December 31, 2018	$	4,326
Change in the estimated fair value of the contingent consideration	510
Contingent consideration, September 30, 2019	$	4,836

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 nelipepimut-S ("NPS") product candidate. The contingent consideration 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 of 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.

6. Legal Proceedings, Commitments and Contingencies

Office Space Rental

The Company has a non-cancelable operating lease for office space in New York, New York, which began August 1, 2018 with a term through July 31, 2020. As disclosed in Note 3, the Company adopted ASC 842 in the first quarter of 2019 and as a result of the adoption, the Company recognized a current operating lease liability of $0.4 million and a non-current operating lease liability of $0.2 million with a corresponding ROU asset of $0.6 million, which is based on the present value of the minimum rental payments of the lease. The discount rate used to account for the Company's operating lease under ASC 842 is the Company’s estimated incremental borrowing rate of 13%. As of September 30, 2019, the lease has a remaining term of less than 1.0 year.

Rent expense related to the Company's operating lease was approximately $0.1 million for the three months ended September 30, 2019 and 2018. Rent expense for the nine months ended September 30, 2019 and 2018 was approximately $0.3 million. Future minimum rental payments under the Company's non-cancelable operating lease are as follows as of September 30, 2019 (in thousands):



	September 30, 2019
Year ending December 31, 2019 (remaining three months)	$	96
Year ending December 31, 2020	224
Total minimum lease payments	320
Less: imputed interest	(14		)
Operating lease liabilities	$	306

Operating lease amortization of the ROU asset was $0.1 million and $0.2 million for the three and nine months ended September 30, 2019, respectively.

Future minimum rental payments under the Company's non-cancelable operating lease as of December 31, 2018 were as follows (in thousands):



	December 31, 2018
2019	$	377
2020	224
Total minimum lease payments	$	601

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 condensed 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, and to which the Company is now subject, as follows:

On February 13, 2017, multiple putative shareholder securities class action complaints were filed in federal court alleging, among other things, that the Company and certain of the Company'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 individual actions were consolidated, lead plaintiffs were named by the federal court 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. Plaintiffs have 30 days from November 13, 2019 to file an amended complain.

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. In June 2018, a derivative complaint was filed in U.S. District Court for the Northern District of California against the Company’s current and former directors, and the Company as a nominal defendant. The plaintiff in the June 2018 case voluntarily withdrew his complaint from the U.S. District Court of the Northern District of California and on August 27, 2018 refiled the complaint in the Court of Chancery of the State of Delaware. 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 March 2017, July 2017, and January 2018 lawsuits are currently stayed pending resolution of motions to dismiss in the referenced securities class action. The defendants in the August 2018 lawsuit filed a motion to dismiss the complaint. On November 13, 2019, the August 2018 lawsuit was dismissed without prejudice by the Court of Chancery of the State of Delaware.

On June 18, 2019, the Company consummated the June 2019 Offering of (i) 527,344 shares of common stock, (ii) 1,472,656 pre-funded warrants exercisable for shares of common stock, and (iii) accompanying common stock warrants to purchase up to an aggregate of 2,000,000 shares of common stock. The shares of common stock and accompanying common stock warrants were sold at a combined price of $7.50 per share and common stock warrant. The pre-funded warrants and accompanying common stock warrants were sold at a combined price of $7.495 per pre-funded warrant and common stock warrant. Each pre-funded warrant represents the right to purchase one share of the Company’s common stock at an exercise price of $0.005 per share. The net proceeds to the Company from the June 2019 Offering, after deducting the underwriting discounts and commissions and other estimated offering expenses, and excluding the exercise of any warrants, were approximately $13.4 million.

As of September 30, 2019, the Company has shares of common stock reserved for future issuance for as follows (in thousands):



	September 30, 2019
Warrants outstanding	302
Stock options outstanding	23
Options reserved for future issuance under the Company’s 2019 Equity Incentive Plan	201
Shares reserved for future issuance under the Employee Stock Purchase Plan	5
Total common stock reserved for future issuance	531

8. Warrants to Acquire Shares of Common Stock

Warrants Issued in 2018

On July 16, 2018, the Company issued the 2018 Warrants to purchase up to an aggregate of 230,400 shares of common stock, with an exercise price per share of $105.00. The 2018 Warrants were immediately exercisable and expire on July 16, 2023.

On March 6, 2019, the Company entered into the Exercise Agreement with one of the holders of the 2018 Warrants. Pursuant to the Exercise Agreement, such warrant holder agreed to exercise for cash up to 76,000 of the 2018 Warrants for shares of common stock at an adjusted exercise price of $55.00 per share for any 2018 Warrants exercised prior to May 31, 2019. In addition to reducing the exercise price of the 2018 Warrants held by the warrant holder, the Exercise Agreement also provided for the issuance of the New Warrants to purchase up to an aggregate of approximately 76,000 shares of common stock at an exercise price of $70.00 per share to be issued on a share-for-share basis in an amount equal to the number of the 2018 Warrants that were cash exercised by the warrant holder prior to May 31, 2019. The New Warrants expire five years from the date of issuance. During the nine months ended September 30, 2019, the warrant holder exercised approximately 63,000 of the 2018 Warrants for gross proceeds to the Company of $3.5 million and approximately 63,000 New Warrants were issued. The reduced exercise price of the 63,000 2018 Warrants exercised by the warrant holder increased the fair value of these Existing Warrants by approximately $0.3 million during the nine months ended September 30, 2019, which is recorded as a deemed dividend increasing the net loss attributable to common stockholders and in additional paid-in capital. The Exercise Agreement expired on May 31, 2019.

Pursuant to the terms of certain warrants issued in connection with our previously outstanding Series A Convertible Preferred stock in March 2018 and May 2018, the exercise price of these warrants was automatically adjusted on March 6, 2019 to $55.00 per share from the previous exercise price of $105.00 per share as a result of the Company's entry into the Exercise Agreement. The Company recognized the $0.3 million increase to the fair value of the warrant liability as a result of the adjusted exercise price as a deemed dividend which increased the net loss attributable to common stockholders during the nine months ended September 30, 2019.

Additionally, the Company agreed to seek the approval of The Nasdaq Stock Market, by November 8, 2019, to reduce the exercise price to $7.50 per share (subject to adjustment for stock splits and the like) of the New Warrants. Prior to November 8, 2019, the Company requested such approval from The Nasdaq Stock Market.

In connection with the June 2019 Offering, the Company reduced the exercise price of the 2018 Warrants to $7.50 per share from the previous exercise price of $105.00 per share. The reduced exercise price of the 2018 Warrants increased the value of fair value of the 2018 Warrants by approximately $0.8 million and is recorded as a deemed dividend increasing net loss attributable to common stockholders and additional paid-in-capital during the nine months ended September 30, 2019.

Pursuant to the terms of certain liability-classified warrants issued in connection with our previously outstanding Series A Convertible Preferred stock in March 2018 and May 2018, the exercise price of these warrants was automatically adjusted on June 18, 2019 to $7.50 per share from the previous exercise price of $55.00 per share. The Company recognized the $0.1 million increase to the fair value of the warrant liability as a result of the adjusted exercise price as a deemed dividend which increased the net loss attributable to common stockholders during the nine months ended September 30, 2019.

July 2019 Investor Agreements

On July 8, 2019, the Company entered into a series of Investor Agreements (collectively, the "Investor Agreements") with certain purchasers of securities (each an "Investor") in connection with the June 2019 Offering. In connection with the Investor Agreements, the parties thereto agreed to, among other things, (i) amend the expiration date of those certain leak-out agreements previously entered into with certain Investors in connection with the June 2019 Offering from August 2, 2019 to August 15, 2019, (ii) amend the warrants issued to such Investors in connection with the June 2019 Offering such that they became cashlessly exercisable pursuant to the terms thereof on July 10, 2019 (the "Warrant Amendment"), and (iii) amend the warrant agreement entered into with Computershare Trust Company, N.A. on June 18, 2019 to reflect the terms of the Warrant Amendment. The reduced exercise price from $25.00 to $0.00 resulted in the Company recognizing a $7.3 million deemed dividend, during the three and nine months ended September 30, 2019, increasing net less loss attributable to common stockholders and additional paid-in capital.

Warrants Classified as Liabilities

Liability-classified warrants consist of warrants to acquire common stock issued in connection with previous equity financings for the Series A Convertible Preferred stock, Galena's February 2017 financing, and various other Galena equity financings that were assumed by the Company at the consummation of the Merger. These warrants may be settled in cash and were determined to not 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 condensed 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:



As of September 30, 2019

Warrant Issuance	Outstanding (in thousands)	Strike price (per share)		Expected term (years)	Volatility %		Risk-free rate %
Series A Convertible Preferred	19	$	7.50	4.01	105.47	%	1.56	%
Galena February 2017	1	$	1,650.00	2.38	107.21	%	1.56	%
Galena Other	3	$	41,494.00	1.68	107.21	%	1.56	%

As of December 31, 2018
Warrant Issuance	Outstanding (in thousands)	Strike price (per share)		Expected term (years)	Volatility %		Risk-free rate %
Series A Convertible Preferred	28	$	7.50	4.76	88.80	%	2.50	%
Galena February 2017	1	$	1,650.00	3.12	94.12	%	2.46	%
Galena Other	3	$	41,494.00	2.43	94.73	%	2.46	%

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, 2019 were as follows (in thousands):



Warrant Issuance	Warrant liability, December 31, 2018		Fair value of warrants granted		Fair value of warrants exercised			Adjustment to exercise price of warrants		Change in fair value of warrants			Warrant liability, September 30, 2019

Warrants Classified as Equity

The Company issued warrants to acquire 6,323 shares of the its common stock at an exercise price of $371.00 per share, maturing five years from issuance, to EQC Private Markets SAC Fund Ltd-EQC Biotech Sely I Fund on December 29, 2017.

The pre-funded warrants exercisable for shares of common stock and warrants to acquire shares of common stock issued during the June 2019 Offering and July 2018 Offering were recorded in equity upon issuance. During its evaluation of equity classification for the pre-funded warrants exercisable for shares of common stock and warrants to acquire shares of common stock issued in the June 2019 Offering, the Company considered the conditions as prescribed within ASC 815-40, Derivatives and Hedging, Contracts in an Entity’s own Equity (“ASC 815-40”). The conditions within ASC 815-40 are not subject to a probability assessment. The pre-funded warrants exercisable for shares of common stock and warrants to acquire shares of common stock do not fall under the liability criteria within ASC 480, Distinguishing Liabilities from Equity, as they are not puttable and do not represent an instrument that has a redeemable underlying security. The pre-funded warrants exercisable for shares of common stock and warrants to acquire shares of common stock do meet the definition of a derivative instrument under ASC 815, but are eligible for the scope exception as they are indexed to the Company’s own stock and would be classified in permanent equity if freestanding. In addition, the Company determined that the down round feature in the warrants to acquires shares of common stock issued in the June 2019 Offering did not preclude equity classification. As described in Note 3, on January 1, 2019, the Company adopted ASU No. 2017-11, which changed the classification of certain equity-linked financial instruments (or embedded features) with down round features. A down round feature no longer precludes equity classification, therefore a freestanding equity feature would no longer be accounted for as a derivative liability at fair value as a result of the existence of a down round feature.

9. Stock-Based Compensation

2017 Equity Incentive Plan

On December 29, 2017, the 2017 Equity Incentive Plan was approved by the stockholders of the Company, and currently allows 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, and currently allows for issuance of up to (i) 200,000 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) any shares of common stock that are represented by awards granted under the Company’s 2017 Equity Incentive Plan that are forfeited, expire or are cancelled without delivery of shares of common stock or which result in the forfeiture of shares of common stock back to the Company on or after September 10, 2019. As of September 30, 2019, an aggregate of 1,018 shares of common stock under the 2017 Equity Incentive Plan 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, 2019, 201,018 shares of common stock were reserved for future grants under the 2019 Equity Incentive Plan.

Options to Purchase Shares of Common Stock

The Company uses the Black-Scholes option-pricing model and the following assumptions were used to determine the fair value of all its stock options granted during the nine months ended September 30, 2019 and 2018:



	Nine Months Ended September 30,
	2019		2018
Risk free interest rate	2.49	%	2.73	%
Volatility	96.57	%	80.83	%
Expected lives (years)	6.20		6.20
Expected dividend yield	—	%	—	%

There were no stock options granted during the three months ended September 30, 2019 and 2018. The weighted-average grant date fair value of options granted during the nine months ended September 30, 2019 and 2018 was $54.00 and $186.50, 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, 2019, there was $1.1 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 2.53 years.

Options exercisable at September 30, 2019	2,486		$	261.22	8.51	$	—

The aggregate intrinsic values of outstanding and exercisable stock options at September 30, 2019 were calculated based on the closing price of the Company’s common stock as reported on the Nasdaq Capital Market on September 30, 2019 of $6.00 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.

RSUs with Time-Based and Performance-Based Conditions

The Company granted Restricted Stock Units ("RSUs") subject to both time-based and performance-based vesting conditions to certain of its employees and non-employees pursuant to the Company's 2016 Incentive Plan. These RSUs vest based on both (i) continued service either over a three-year measurement period or at the end of the required service period and (ii) the achievement of a liquidity event. The initial vesting date for these RSUs was February 27, 2018. The liquidity event, as defined in the relevant RSU grant agreements, will be satisfied upon the earlier of either: (a) change of control or (b) a qualified public offering. During the three months ended September 30, 2019, approximately 230 shares of common stock were issued in connection upon the vesting of RSUs. As of September 30, 2019, there were no RSUs outstanding under any of the Company's incentive plans.

10. Subsequent Events

The Company evaluated all events or transactions that occurred after September 30, 2019 up through the date these financial statements were issued. Other than as disclosed elsewhere in the notes to the condensed consolidated financial statements, including below, the Company did not have any material subsequent events.

On October 29, 2019, the Company entered into a Distribution Agreement with Maxim Group LLC as described in Notes 3 and 7.

On November 6, 2019, the Company filed a certificate of amendment to its amended and restated Certificate of Incorporation to effect a 1 for 50 reverse stock split of the Company's outstanding shares of common stock which became effective on November 7, 2019 as described in Note 3.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This management’s discussion and analysis of financial condition as of September 30, 2019 and results of operations for the three and nine months ended September 30, 2019 and 2018, respectively, should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the 2018 Annual Report, and our other public reports filed with the SEC.

Overview

We are a late-stage clinical biopharmaceutical company focused on the development of novel cancer immunotherapeutics for a broad range of indications.

Galinpepimut-S, or GPS

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 November 2018, following discussions with the U.S. Food and Drug Administration, or FDA, regarding a clinical trial design and biostatistical plan, we commenced preparations for a Phase 3 randomized open-label clinical trial for GPS monotherapy compared to Investigator's choice of best available therapies, or BAT, in patients with acute myeloid leukemia, or AML, in the maintenance setting after achievement of their second complete remission, or CRem2, following successful completion of second-line antileukemic therapy, or the REGAL study. This trial is expected to serve as the basis for a Biologics License Application, or BLA, submission, subject to positive results. We are on track to initiate this Phase 3 trial in the fourth quarter of 2019. The study is expected to enroll approximately 116 patients at approximately 50 clinical sites in the United States and Europe (Germany, Netherlands, Belgium, Poland and the Czech Republic) and is contemplated to have a planned interim safety and futility analysis after 80 events (deaths). The primary endpoint of the study is overall survival, or OS. The study is powered at not less than 90% under an assumed hazard ratio, or HR, of 0.52 based on an assumed median OS of 5.4 months for BAT vs. 10.4 months for GPS. In order to attain statistical significance, a HR of less than 0.60 needs to be observed at interim analysis or a HR of less than 0.675 needs to be observed at final analysis. We expect that the interim analysis will occur approximately five months after the final patient has been randomized. We anticipate this interim data by the end of 2021. Secondary endpoints to be measured include leukemia-free survival, antigen-specific T-cell immune response dynamics, measurable residual disease by multigene array, and assessments of AML clonal evolution and inflammasome molecular signatures in the tumor microenvironment in bone marrow biopsy samples.

On October 11, 2019, we entered into Work Order #1, or the Work Order, with Worldwide Clinical Trials Limited, or Worldwide, a global contract research organization, or CRO, to provide certain services with respect to our GPS Phase 3 AML clinical trial. The Work Order was entered into pursuant to a Master Services Agreement with Worldwide, effective as of August 15, 2019. Worldwide and the Company entered into a Letter of Intent dated August 15, 2019, or the LOI, for the performance of certain start-up services related to our Phase 3 clinical trial of GPS. The LOI was superseded by the Work Order.

In the fourth quarter of 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, Keytruda® (pembrolizumab). In July 2019, we dosed the first patient in this trial. We plan to enroll approximately 90 patients at up to 20 centers in the United States. The trial is initially evaluating patients with ovarian cancer (second or third line) and colorectal cancer (third or fourth line), to be followed by patients with AML who are unable to attain deeper morphological response than partial on hypomethylating agents and who are not eligible for allogeneic hematopoietic stem cell transplant, and patients with triple negative breast cancer, or TNBC (second line), and small cell lung cancer (second line). We expect initial clinical data by the second half of 2020.

In November 2019, we received follow-up data from our Phase 1 clinical trial of GPS in combination with nivolumab to treat WT1 positive patients with ovarian cancer in second- or third-line remission. Topline data from this study at ten months had been presented at the June 2018 meeting of the American Society of Clinical Oncology. These follow-up data now show that three of the eleven patients enrolled in the study have continued to show no signs of disease progression. The mean progression free survival, or PFS, for these three patients is 35.4 months from the initiation of salvage chemotherapy or mean PFS of 30.1 months from the first administration of GPS plus nivolumab. Based on this follow-up information, the estimated two-year PFS rate for this study is now 27.3% for the intent-to-treat patients (n=11) and approximately 30% for patients who received greater than two doses of GPS and nivolumab (n=10), as compared to a historical 3% to 10% PFS rate for patients receiving only salvage chemotherapy. No new serious adverse events were noted during the longer follow-up period.

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, malignant pleural mesothelioma, or 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, or HER2, expressing cancers. Data presented in 2018 from our Phase 2b clinical trial of the combination of trastuzumab (Herceptin®) plus NPS in HER1/2+ 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 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. In October 2018, the Data Safety Monitoring Board, or DSMB, unanimously concluded that the final analysis of the Phase 2b study data, with a median follow-up of 26 months, confirmed that TNBC patients should be the key target population for the development of trastuzumab plus NPS in the adjuvant setting in early-stage HER2 1+/2+ breast cancer patients. We are having ongoing discussions with the FDA to define an optimal path for further development of the combination of NPS plus trastuzumab in TNBC.

FBP-targeting bivalent vaccine (GALE-301/-302)

GALE-301 and GALE 302 are cancer immunotherapies that target the E39 peptide derived from the folate binding protein, or FBP. In a Phase 1/2a investigator sponsored trial, or IST, assessing GALE-301 in ovarian and endometrial cancers, we observed improvement in the 24-month DFS rate, in a small number of patients treated with the optimal dose. We are evaluating GALE-301/302 for potential internal development in a Phase 2 setting for ovarian cancer, strategic partnership, or other type of candidate rationalization.

Recent Developments

On June 18, 2019, we consummated an underwritten public offering, or the June 2019 Offering, of (i) 527,344 shares of common stock, (ii) 1,472,656 pre-funded warrants exercisable for shares of common stock, and (iii) accompanying common stock warrants to purchase up to an aggregate of 2,000,000 shares of common stock. The shares of common stock and accompanying common stock warrants were sold at a combined price of $7.50 per share and common stock warrant. Each common stock warrant sold with the shares of common stock represented the right to purchase one share of common stock at an exercise price of $25.00 per share and, commencing July 10, 2019, could be exercised pursuant to the terms thereof on a cashless basis, at the option of the holder, in whole or in part, for one share of common stock, if the weighted average price of the common stock on any trading day immediately prior to the exercise date is lower than the then-applicable exercise price per share. As of September 30, 2019, 1,997,740 of the June 2019 Offering warrants were cashlessly exercised and 2,260 warrants remain outstanding. The pre-funded warrants and accompanying common stock warrants were sold at a combined price of $7.495 per pre-funded warrant and common stock warrant. The pre-funded warrants are exercisable immediately at an exercise price of $0.005 per share. As of September 30, 2019, all of the pre-funded warrants sold in the June 2019 Offering were exercised.

The net proceeds to us from the June 2019 Offering, after deducting underwriting discounts and commissions and other estimated offering expenses, and excluding the exercise of any warrants, was approximately $13.4 million.

On July 8, 2019, we entered into a series of agreements, or the Investor Agreements, with certain purchasers of securities, or Investors, in connection with the June 2019 Offering. In connection with the Investor Agreements, the parties thereto agreed to, among other things, (i) amend the expiration date of those certain leak-out agreements previously entered into with certain Investors in connection with the June 2019 Offering from August 2, 2019 to August 15, 2019, (ii) amend the warrants issued to such Investors in connection with the June 2019 Offering such that they became cashlessly exercisable pursuant to the terms thereof on July 10, 2019 (the "Warrant Amendment"), and (iii) amend the warrant agreement entered into with Computershare Trust Company, N.A. on June 18, 2019, to reflect the terms of the Warrant Amendment.

On October 29, 2019, we entered into an Equity Distribution Agreement, or Distribution Agreement, with Maxim Group LLC, or the Agent, pursuant to which we may offer and sell shares of common stock through the Agent having an aggregate offering price up to $5.0 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. Sales of the shares, if any, under the Distribution Agreement may be made in transactions that are deemed to be "at the market offering" as defined in Rule 415 under the Securities Act. We have no obligation to sell any shares under the Distribution Agreement, and may use the Distribution Agreement until it is terminated by either the Agent or us, as permitted thereby. Shares sold, if any, under the Distribution Agreement will be offered and sold pursuant to the our effective registration statement on Form S-3. Subsequent to September 30, 2019, we sold 322,719 shares of common stock pursuant to the Distribution Agreement for net proceeds of $1.9 million.

On November 7, 2019, we effected a 1-for-50 reverse stock split of our outstanding shares of common stock, outstanding options to purchase shares of our common stock and warrants to acquire shares of common stock. In addition, the number of shares of common stock subject to stock options or similar right authorized under our equity incentive plans and employee stock purchase plan were proportionately adjusted for the reverse stock split. Further, the per share exercise prices for options granted under such plans was proportionately adjusted for the reverse stock split. The reverse stock split reduced the number of shares of our common stock that were outstanding at November 7, 2019 from 227,800,147 to 4,549,208, after the cancellation of fractional shares. No fractional shares were issued in connection with the reverse stock split. Stockholders who otherwise held fractional shares of our common stock as a result of the reverse stock split received a cash payment in lieu of such fractional shares. These condensed consolidated financial statements give retroactive effect to such reverse stock split, and all share and per share amounts have been adjusted accordingly.

Components of Results of Operations

Research and Development

Research and development expenses consist 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 contract research organizations, or CROs, as well as investigative sites and consultants that conduct our preclinical studies and clinical trials;


•	manufacturing expenses;


•	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:


•	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; and


•	the commercialization of current and future product candidates.

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, 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.

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 significantly over the next several years as we initiate additional and late stage clinical trials and as our research and development related personnel costs increase, including stock-based compensation.

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. 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 U.S. Securities and Exchange Commission reporting requirements, investor relations costs, and director and officer insurance premiums associated with being a public company.

We anticipate that our general and administrative expenses will decrease as we focus on managing outside service providers in order to prudently preserve capital. If and when we believe that regulatory approval of a product candidate appears likely, we anticipate that an increase in payroll and 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.

Non-Operating Income (Expense), Net

Non-operating income (expense), net consists of changes in fair value of our warrant liability, changes in fair value of our contingent consideration, loss on settlement of liability-classified warrants, and interest expense, net. Interest expense, net primarily reflects interest expense incurred on our convertible term notes and other loans held with current and former stockholders, offset by the interest earned from our cash and cash equivalents.

Critical Accounting Policies and Estimates

In the 2018 Annual Report, we disclosed our critical accounting policies and estimates upon which our financial statements are derived.

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

Research and Development

Research and development expenses were $1.8 million for the three months ended September 30, 2019 compared to $1.7 million for the three months ended September 30, 2018. The $0.1 million increase was primarily attributable to a $0.2 million increase in manufacturing related expenses for GPS and a $0.1 million increase in clinical trial expenses due to our ongoing basket trial of GPS in combination with pembrolizumab and start-up costs for our Phase 3 clinical trial of GPS as a monotherapy in AML, partially offset by $0.1 million decrease in personnel related expenses due to reduced headcount and $0.1 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 the ongoing basket trial of GPS in combination with pembrolizumab, and our planned Phase 3 trial of GPS in AML.

Research and development expenses were $5.0 million for the nine months ended September 30, 2019 compared to $5.1 million for the nine months ended September 30, 2018. The $0.1 million decrease was primarily attributable to a $0.9 million decrease in personnel related expenses due to reduced headcount and $0.1 million decrease in other research and development expenses. This decrease was partially offset by a $0.5 million increase in manufacturing related expenses for GPS, a $0.3 million increase in licensing fees, and a $0.1 million increase in clinical trial expenses due to our ongoing basket trial of GPS in combination with pembrolizumab and start-up costs for our Phase 3 clinical trial of GPS as a monotherapy in AML.

General and Administrative

General and administrative expenses were $2.4 million for the three months ended September 30, 2019 compared to $1.3 million for the three months ended September 30, 2018. The $1.1 million increase was due to a $1.2 million increase in legal fees and $0.1 million increase in public company costs, partially offset by a $0.2 million decrease in personnel related expenses due to reduced headcount. During the three months ended September 30, 2018, we recorded legal fee reimbursements totaling $2.5 million related to a litigation settlement and received an additional $0.5 million from our insurance carrier for previous amounts paid in excess of our deductible related to a previously settled litigation. These amounts were recorded as a reduction of our general and administrative expenses for the three months ended September 30, 2018.

General and administrative expenses were $7.5 million for the nine months ended September 30, 2019 compared to $10.1 million for the nine months ended September 30, 2018. The $2.6 million decrease was due to a $0.6 million decrease in legal fees, a $0.5 million decrease in personnel related expenses due to reduced headcount, a $0.5 million decrease in public company costs, a $0.4 million decrease in accounting and audit fees, a $0.3 million decrease in outsourced consulting, and a $0.3 million decrease in other expenses.

Non-Operating Income (Expense), Net

Non-operating income (expense), net for the three and nine months ended September 30, 2019 and 2018, respectively, was as follows (in thousands):



	Three Months Ended September 30,									Nine Months Ended September 30,
	2019			2018			Change			2019			2018			Change
Change in fair value of warrant liability	$	(49	)	$	2,241		$	(2,290	)	$	1,108		$	5,340		$	(4,232	)
Change in fair value of contingent consideration	(28		)	(162		)	134			(510		)	(4,025		)	3,515
Loss on settlement of liability-classified warrants	—			—			—			—			(727		)	727
Gain on extinguishment of debt	—			766			(766		)	—			766			(766		)
Interest income (expense), net	59			(74		)	133			91			(292		)	383
Total non-operating income (expense), net	$	(18	)	$	2,771		$	(2,789	)	$	689		$	1,062		$	(373	)

Net non-operating expense was nominal during the three months ended September 30, 2019. Net non-operating income of $0.7 million during the nine months ended September 30, 2019 was primarily due to a $1.1 million gain arising and $0.1 million of interest income from the decrease in the fair value of liability-classified warrants to acquire shares of common stock, partially offset by a $0.5 million increase in the fair value of the contingent consideration liability. The decrease in the estimated fair value of our warrant liability was primarily due to decreases in our common stock price.

Net non-operating income of $2.8 million during the three months ended September 30, 2018 was primarily due to a $2.2 million gain arising from the decrease in the fair value of liability-classified warrants to acquire shares of common stock and a $0.8 million gain on extinguishment of debt partially offset by a $0.2 million increase in the fair value of the contingent consideration liability, and $0.1 million of interest expense. Net non-operating income of $1.1 million during the nine months ended September 30, 2018 was primarily due to a $5.3 million gain arising from the decrease in the fair value of liability-classified warrants to acquire shares of common stock and a $0.8 million gain on extinguishment of debt partially offset by a $4.0 million increase in the fair value of the contingent consideration liability, a $0.7 million loss on settlement of liability-classified warrants to acquire shares of common stock, and $0.3 million of interest expense. The change in the estimated fair value of the contingent consideration during the nine months ended September 30, 2018 reflects an adjusted probability and time line for the potential approval of NPS associated with the positive interim data from the Phase 2b investigator-sponsored clinical trial of trastuzumab +/- NPS that was announced on April 2, 2018.

The $0.8 million gain on extinguishment of debt during the three and nine months ended September 30, 2018 relates to the settlement with the holder of our formerly outstanding senior secured debenture. We were previously involved in litigation regarding the senior secured debenture, and entered into a settlement agreement in November 2018. As a result of the settlement, the $0.8 million of additional interest that was due at maturity was forgiven.

The $0.7 million loss on settlement of liability-classified warrants during the three and nine months ended September 30, 2018 relates to warrants to acquire shares of common stock issued by Galena in February 2017 that were assumed in the Merger. During the nine months ended September 30, 2018, a total of 10,686 of the Galena February 2017 liability-classified warrants to acquire shares of common stock were canceled under various warrant exchange agreements. We issued 1,086 shares of our common stock in exchange for the surrender and cancellation of warrants to acquire 2,433 shares of our common stock and $1.0 million in convertible promissory notes in exchange for the surrender and cancellation of warrants to acquire 8,253 shares of our common stock. The fair value of the consideration exchanged totaling $1.3 million exceeded the fair value of the warrant liability of the warrants canceled by $0.7 million and is recorded as loss on settlement of liability-classified warrants in the condensed consolidated statement of operations for the three and nine months ended September 30, 2018.

Interest income during the three and nine months ended September 30, 2019 consisted of interest earned from our cash and cash equivalents. Interest expense, net for the three and nine months ended September 30, 2018 primarily consisted of interest expense incurred on our previously outstanding long-term debt, partially offset by nominal interest earned from our cash and cash equivalents.

The change in fair value of warrant liability, change in fair value of contingent consideration, loss on settlement of liability-classified warrants, and gain on extinguishment of debt are all non-cash in nature.

Income Tax Expense

There was no income tax expense for the three and nine months ended September 30, 2019. For the nine months ended September 30, 2018, we recognized income tax expense of $0.2 million. We continue to maintain a full valuation allowance against our net deferred tax assets.

Liquidity and Capital Resources

We have not generated any revenue from product sales or collaboration and licensing agreements in the nine months ended September 30, 2019 and 2018. Since inception, we have incurred net losses, used net cash from our operations, and have funded substantially all of our operations through proceeds of the sale of equity securities and convertible notes.

On June 18, 2019, we received $13.8 million in net proceeds from the sale of shares of common stock, pre-funded warrants to acquire shares of common stock, and accompanying common stock warrants to acquire shares of common stock. We are using the proceeds of this offering to advance our GPS development program. We continue to explore other potential transactions for advancing our development plans and maximizing shareholder value. In addition to the June 2019 financing, during the nine months ended September 30, 2019, we received $3.6 million in net proceeds from the exercise of warrants and pre-funded warrants.

On October 29, 2019, we entered into an Equity Distribution Agreement, or Distribution Agreement, with Maxim Group LLC, or the Agent, pursuant to which we may offer and sell shares of common stock through the Agent having an aggregate offering price up to $5.0 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. Sales of the shares, if any, under the Distribution Agreement may be made in transactions that are deemed to be "at the market offering" as defined in Rule 415 under the Securities Act. We have no obligation to sell any shares under the Distribution Agreement, and may use the Distribution Agreement until it is terminated by either the Agent or us, as permitted thereby. Shares sold, if any, under the Distribution Agreement will be offered and sold pursuant to our effective registration statement on Form S-3. Subsequent to September 30, 2019, we sold 322,719 shares of common stock pursuant to the Distribution Agreement for net proceeds of $1.9 million.

As of September 30, 2019, we had an accumulated deficit of $93.7 million, cash and cash equivalents of $9.1 million, and restricted cash and cash equivalents of $0.1 million. In addition, we had accounts payable and accrued expenses and other current liabilities of $5.3 million as of September 30, 2019. These matters raise substantial doubt about our ability to continue as a going concern. Our condensed consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. We anticipate incurring additional losses until such time, if ever, that we can generate significant sales of any current or future product candidates in development.

This going concern assumption is based on management’s assessment of the sufficiency of our current and future sources of liquidity considering whether or not it is probable we will be able to meet our obligations as they become due for at least one year from the date our condensed consolidated financial statements are available to be issued, and if not, whether our liquidation is imminent. Our management believes that our cash of $9.1 million as of September 30, 2019, together with the net proceeds received from the sale of common stock pursuant to the Distribution Agreement subsequent to September 30, 2019, will enable us to fund our operating expenses and capital expenditure requirements through the third quarter of 2020. We will require additional financing to fund our operations thereafter and to commercially develop any current or future product candidates. We may be required to delay, scale back or eliminate some or all of our research and development programs and place certain activities on hold, or cease operations if we are unable to raise funds as needed. Other than the Distribution Agreement, we currently do not have any commitments to obtain additional funds and may be unable to obtain sufficient funding in the future on acceptable terms, if at all. Our management continues to evaluate different strategies to obtain the required funding for future operations. These strategies may include public and private placements of equity and/or debt securities, payments from potential strategic research and development collaborations, and licensing and/or marketing arrangements with pharmaceutical companies. Additionally, we continue to engage in active discussions with global and regional pharmaceutical companies for licensing and/or co-development rights to our late- and early-stage pipeline candidates. To the extent that we raise additional capital through the sale of our common stock, the interests of our current stockholders may be diluted. If we issue additional preferred stock or convertible debt securities, it could affect the rights of our common stockholders or reduce the value of our common stock or any outstanding classes of preferred stock. There can be no assurance that these future funding efforts will be successful.

Our future operations are highly dependent on a combination of factors, including (i) the timely and successful completion of additional financing discussed above, (ii) our ability to complete revenue-generating partnerships with pharmaceutical 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.

Cash Flows

The following table summarizes our cash flows from operating and financing activities for the nine months ended September 30, 2019 and 2018 (amounts in thousands):



	NIne Months Ended September 30,
	2019			2018
Net cash (used in) provided by:
Operating activities	$	(13,467	)	$	(25,867	)
Financing activities	17,250			23,199
Net increase (decrease) in cash, cash equivalents, restricted cash, and restricted cash equivalents	$	3,783		$	(2,668	)

Net Cash Flow from Operating Activities

Net cash used in operating activities of $13.5 million during the nine months ended September 30, 2019 was primarily attributable to our net loss of $11.9 million. This amount was impacted by a non-cash gain of $1.1 million from the decrease in the fair value of liability-classified warrants, partially offset by various net non-cash charges of $0.9 million, which was comprised of $0.5 million increase in the fair value of our contingent consideration liability, and a $0.4 million increase in stock-based compensation. The net change in our operating assets and liabilities of $1.4 million is primarily attributable to an increase in prepaid expenses of $0.5 million, and a $0.9 million decrease in our accounts payable and accrued expenses and other current liabilities as we paid down longer outstanding payables during the nine months ended September 30, 2019.

Net cash used in operating activities of $25.9 million during the nine months ended September 30, 2018 was primarily attributable to our net loss of $14.3 million. This amount was offset by various net non-cash charges of $0.4 million, which was comprised of $4.0 million increase in the fair value of our contingent consideration liability, $1.3 million increase in the fair value of common stock issued in connection with litigation settlements, and $0.7 million loss on settlement of liability-classified warrants, partially offset by a gain of $5.3 million from the decrease in the fair value of liability-classified warrants and a $0.8 million gain on extinguishment of debt. The net change in our operating assets and liabilities of $11.9 million was primarily attributable to an increase in prepaid expenses and other receivables of $7.6 million related to the settlement of litigation that was received in November 2018 and a decrease of $4.3 million in our accounts payable and accrued expenses.

Net Cash Flow from Financing Activities

We generated $17.3 million of net cash from financing activities for the nine months ended September 30, 2019. We received $13.7 million in net proceeds from our June 2019 Offering through the sale of shares of common stock, pre-funded warrants to acquire shares of common stock, and accompanying common stock warrants to acquire shares of common stock. As of September 30, 2019, we had $0.2 million of offering expenses from the June 2019 Offering in accounts payable and accrued expenses that are expected to be paid in the fourth quarter of 2019. In addition, during the nine months ended September 30, 2019, we received $3.6 million in net proceeds from the exercise of warrants and pre-funded warrants.

We generated $23.2 million of net cash from financing activities for the nine months ended September 30, 2018, which was primarily attributable to $21.6 million in net proceeds from the sale of common stock and common stock warrants, $9.6 million in net proceeds from the sale of the Series A Convertible Preferred and warrants, partially offset by $7.5 million in principal payments on our previously outstanding senior secured debenture and $0.5 million in dividends paid.

Off-Balance Sheet Arrangements

We have not entered into any off-balance sheet financing arrangements as of September 30, 2019.

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. Based on these evaluations, the Certifying Officers have concluded, that, as of the end of the period covered by this Quarterly Report on Form 10-Q:


(a)	our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms; and


(b)	our disclosure controls and procedures were effective to provide reasonable assurance that material information required to be disclosed by us in the reports we file or submit under the Exchange Act was accumulated and communicated to our management, including the Certifying Officers, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended September 30, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Please refer to Note 6 (Legal Proceedings, Commitments and Contingencies) to our condensed consolidated financial statements contained in Part I, Item 1 (Financial Statements) of this Quarterly Report on Form 10-Q, which is incorporated into this item by reference.

ITEM 1A. RISK FACTORS

Please refer to our note on forward-looking statements on page 2 of this Quarterly Report on Form 10-Q, which is incorporated into this item by reference.

In addition to the other information set forth in this report, you should carefully consider the risk factors discussed in our 2018 Annual Report. The risks described in such 2018 Annual Report are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition, operating results and stock price.

Our common stock may be delisted from the Nasdaq Capital Market which could negatively impact the price of our common stock, liquidity and our ability to access the capital markets.

The listing standards of the Nasdaq Capital Market provide that a company, in order to qualify for continued listing, must maintain a minimum stock price of $1.00 and satisfy standards relative to minimum stockholders’ equity, minimum market value of publicly held shares and various additional requirements. If we fail to comply with all listing standards applicable to issuers listed on the Nasdaq Capital Market, our common stock may be delisted. If our common stock is delisted, it could reduce the price of our common stock and the levels of liquidity available to our stockholders. In addition, the delisting of our common stock could materially adversely affect our access to the capital markets and any limitation on liquidity or reduction in the price of our common stock could materially adversely affect our ability to raise capital. Delisting from the Nasdaq Capital Market could also result in other negative consequences, including the potential loss of confidence by suppliers, customers and employees, the loss of institutional investor interest and fewer business development opportunities.

As previously reported, on May 31, 2019, we received a letter from Nasdaq indicating that, based upon the closing bid price of our common stock for the last 30 consecutive business days, we did not meet the minimum bid price of $1.00 per share required for continued listing on the Nasdaq Capital Market pursuant to Minimum Bid Price Rule. We have been provided an initial period of 180 calendar days, or until November 27, 2019, to regain compliance with the Minimum Bid Price Rule. The letter also indicated that if at any time before November 27, 2019 the closing bid price for our common stock is at least $1.00 for a minimum of ten consecutive business days, Nasdaq will provide written notification to the company that it complies with the Minimum Bid Price Rule. While we effected a 1-for-50 reverse stock split of our common stock on November 7, 2019, as of the date of this Quarterly Report on Form 10-Q, the closing bid price of our common stock has not been at least $1.00 for ten consecutive business days and therefore there can be no assurance that the reverse stock split will allow us to regain compliance with the Minimum Bid Price Rule. If we do not regain compliance with the Minimum Bid Price Rule by November 27, 2019, we may be eligible for a second compliance period of 180 calendar days, provided that we meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Capital Market, with the exception of the bid price requirement, and notify Nasdaq of our intention to cure the deficiency during such second compliance period, including by effecting a reverse stock split, if necessary. If we do not regain compliance with the Minimum Bid Price Rule by November 27, 2019 and are not eligible for a second compliance period at that time, Nasdaq will provide written notification to us that our common stock may be delisted. At that time, we may appeal Nasdaq’s delisting determination to a Nasdaq hearings panel. If we timely appeal, our common stock would remain listed pending the panel’s decision. There can be no assurance that, if we do appeal the delisting determination by Nasdaq to the panel, such appeal would be successful.

We are, and in the future may be, subject to legal or governmental proceedings that could adversely affect our financial condition and our business.

Our predecessor company, Galena, was involved in multiple legal and governmental proceedings, including stockholder class actions and derivative suits, both state and federal, some of which are ongoing. As a result of a cease and desist order issued by the SEC on April 10, 2017 and our related settlement with the SEC, or the SEC Settlement, we are currently an “ineligible issuer” as the term is defined under Rule 405 promulgated under the Securities Act. This could make it more difficult for us to raise necessary financing in the future. If we fail to comply with the terms of the SEC Settlement in the future, it could have significant additional adverse consequences to us.

We may, in the future, become subject to additional legal and governmental actions that will also require us to expend time and resources. Future legal and governmental proceedings may not qualify for coverage under, or may exceed the limit of, our applicable directors and officers liability insurance policies and could have a material adverse effect on our financial condition, liquidity, and results of operations. An unfavorable outcome in any of these matters could damage our business and reputation or result in additional claims or proceedings against us. We can make no assurances as to the time or resources that will need to be devoted to any new or future matters or their outcome, or the impact, if any, that these matters or any resulting legal or governmental proceedings may have on our business or financial condition but any further action in respect of any such matter by a governmental agency could have a material adverse effect on our results of operation and our business and prospects.
