CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. All statements other than statements of historical facts contained in this Quarterly Report are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. All statements other than statements of historical fact contained in this Quarterly Report, including without limitation statements regarding our plans to develop and commercialize our product candidates, the timing of our ongoing or planned clinical trials, the timing of and our ability to obtain and maintain regulatory approvals, the clinical utility of our product candidates, our commercialization, manufacturing capabilities and strategy, our expectations about the willingness of healthcare professionals to use our product candidates, the sufficiency of our cash, cash equivalents and short-term investments and our ability to raise additional capital to fund our operations, the anticipated impact of the COVID-19 pandemic on our business, and the plans and objectives of management for future operations, capital needs, and capital expenditures are forward-looking statements.

The forward-looking statements in this Quarterly Report are only predictions and are based largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. These forward-looking statements speak only as of the date of this Quarterly Report and are subject to a number of known and unknown risks, uncertainties and assumptions that could cause actual results to differ materially from those projected in the forward-looking statements, including, but not limited to, the following: our limited operating history; anticipating continued losses for the foreseeable future; needing substantial funding and the ability to raise capital; our dependence on avasopasem manganese (GC4419) and our other product candidates; uncertainties inherent in the conduct of clinical trials; difficulties or delays enrolling patients in clinical trials; the FDA’s acceptance of data from clinical trials outside the United States; undesirable side effects from our product candidates; risks relating to the regulatory approval process; failure to capitalize on more profitable product candidates or indications; ability to receive and/or maintain Breakthrough Therapy Designation or Fast Track Designation for product candidates; failure to obtain regulatory approval of product candidates in the United States or other jurisdictions; ongoing regulatory obligations and continued regulatory review; risks related to commercialization; risks related to competition; ability to retain key employees and manage growth; risks related to intellectual property; inability to maintain collaborations or the failure of these collaborations; our reliance on third parties; the possibility of system failures or security breaches; liability related to the privacy of health information obtained from clinical trials and product liability lawsuits; unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives; environmental, health and safety laws and regulations; the impact of the COVID-19 pandemic on our business and operations, including preclinical studies and clinical trials, and general economic conditions; risks related to ownership of our common stock; significant costs as a result of operating as a public company; and those described under the sections in our Annual Report on Form 10-K for the year ended December 31, 2021 and this Quarterly Report entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise.

NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

1.

Organization and description of business

Galera Therapeutics, Inc. was incorporated as a Delaware corporation on November 19, 2012 (inception) and together with its subsidiaries (the Company, or Galera) is a clinical stage biopharmaceutical company focused on developing and commercializing a pipeline of novel, proprietary therapeutics that have the potential to transform radiotherapy in cancer. Galera's technology consists of selective small molecule dismutase mimetics that are in late-stage development in patients with cancer. Avasopasem manganese (GC4419, also referred to as avasopasem) is in development for radiotherapy-induced toxicities, including severe oral mucositis (SOM) in patients with locally advanced head and neck cancer (HNC) and esophagitis in patients with lung cancer. In February 2018, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation to avasopasem for the reduction of SOM induced by radiotherapy with or without systemic therapy. Galera’s second dismutase mimetic product candidate, rucosopasem manganese (GC4711, also referred to as rucosopasem), is in clinical-stage development to augment the anti-cancer efficacy of stereotactic body radiation therapy (SBRT) in patients with non-small cell lung cancer (NSCLC) and locally advanced pancreatic cancer (LAPC).

In December 2021, the Company announced corrected topline efficacy results from a Phase 3 trial (referred to as the ROMAN trial) evaluating avasopasem for the reduction of radiotherapy-induced SOM in patients with locally advanced HNC. The Company had previously announced topline results from the ROMAN trial in October 2021. Upon further analysis following the October topline data announcement, an error by the contract research organization was identified in the statistical program. Correction of this error resulted in improved p-values for the primary and secondary endpoints. The corrected results demonstrated efficacy across multiple SOM endpoints with a statistically significant reduction on the primary endpoint of reduction in the incidence of SOM and a statistically significant reduction on the secondary endpoint of number of days of SOM. The ROMAN trial is the Company’s second randomized trial conducted in patients with HNC to achieve statistical significance and demonstrate improved clinical benefit in reducing SOM. Based on these data, the Company plans to submit to the FDA a New Drug Application, or NDA, of avasopasem for radiotherapy-induced SOM by the end of 2022.

In addition to developing avasopasem for the reduction of normal tissue toxicity from radiotherapy, the Company is developing its second dismutase mimetic product candidate, rucosopasem, to increase the anti-cancer efficacy of higher daily doses of radiotherapy, or SBRT. In September 2021, in support of rucosopasem, the Company announced final results from its Phase 1/2 pilot trial of avasopasem in combination with SBRT in patients with unresectable or borderline resectable LAPC. In this proof-of-concept trial, survival and tumor outcome benefits were observed. The Company used its observations from this pilot trial to inform the design of rucosopasem clinical trials in combination with SBRT. The Company has successfully completed Phase 1 trials of intravenous rucosopasem in healthy volunteers and is currently evaluating rucosopasem in combination with SBRT in a Phase 1/2 safety and anti-cancer efficacy trial in NSCLC, and a Phase 2b trial of rucosopasem in combination with SBRT in patients with LAPC.

Liquidity

The Company has incurred recurring losses and negative cash flows from operations since inception and has an accumulated deficit of $331.5 million as of March 31, 2022. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales of its product candidates currently in development. The Company expects its existing cash, cash equivalents and short-term investments as of March 31, 2022 will enable the Company to fund its operating expenses and capital expenditure requirements into the second half of 2023. In the future, if the Company is not able to continue to raise sufficient capital to fund its operations, the Company may decide to delay or discontinue certain activities, including planned research and development activities, hiring plans, manufacturing activities and commercial preparation efforts. In December 2020, the Company filed a registration statement with the Securities and Exchange Commission (SEC) which covers the offering, issuance and sale of up to $200.0 million in Company securities, which includes an Open Market Sale Agreement with Jefferies LLC (the Sales Agreement) covering the offering, issuance and sale of up to a maximum aggregate offering price of $50.0 million of the Company’s common stock, which could be utilized to raise funding for future operating expenses and capital expenditure requirements. During the three months ended March 31, 2022, the Company sold approximately 0.3 million shares of common stock and received net proceeds of $1.1 million pursuant to the Sales Agreement. As of March 31, 2022, there remained approximately $40.6 million available under the Sales Agreement.

Basis of presentation and significant accounting policies

The summary of significant accounting policies disclosed in the Company’s annual consolidated financial statements for the years ended December 31, 2021 and 2020 included in the Company’s annual report on Form 10-K filed with the SEC on March 10, 2022 have not materially changed, except as set forth below.

GALERA THERAPEUTICS, INC.

NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS
 

Basis of presentation and consolidation

The accompanying unaudited interim consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information. 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).

In the opinion of management, the accompanying interim consolidated financial statements include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the financial statements) considered necessary to present fairly the Company’s financial position as of March 31, 2022 and its results of operations for the three months ended March 31, 2022 and 2021, and statements of changes in stockholder’s equity (deficit) and cash flows for the three months ended March 31, 2022 and 2021. Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022, or for any future period. The interim consolidated financial statements, presented herein, do not contain the required disclosures under U.S. GAAP for annual financial statements. Therefore, these interim consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and related notes as of and for the year ended December 31, 2021, included in the Company’s annual report on Form 10-K and filed with the SEC on March 10, 2022.

Use of estimates

The preparation of unaudited interim consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited interim consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the unaudited interim consolidated financial statements in the period they are determined to be necessary. Significant areas that require management’s estimates include share-based compensation assumptions, royalty purchase liability assumptions and accrued research and development expenses.

Research and development expenses

Research and development costs are expensed as incurred and consist primarily of funds paid to third parties for the provision of services for product candidate development, clinical and preclinical development and related supply and manufacturing costs, and regulatory compliance costs. The Company accrues and expenses preclinical studies and clinical trial activities performed by third parties based upon estimates of the proportion of work completed over the term of the individual trial and patient enrollment rates in accordance with agreements with clinical research organizations and clinical trial sites. The Company determines the estimates by reviewing contracts, vendor agreements and purchase orders, and through discussions with internal clinical personnel and external service providers as to the progress or stage of completion of trials or services and the agreed-upon fee to be paid for such services. However, actual costs and timing of clinical trials are highly uncertain, subject to risks and may change depending upon a number of factors, including the Company’s clinical development plan.

Management makes estimates of the Company’s accrued expenses as of each balance sheet date in the Company’s consolidated financial statements based on facts and circumstances known to the Company at that time. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company will adjust the accrual accordingly. Nonrefundable advance payments for goods and services, including fees for process development or manufacturing and distribution of clinical supplies that will be used in future research and development activities, are deferred and recognized as expense in the period that the related goods are consumed or services are performed.

In September 2020, the Company was awarded a Small Business Innovation Research grant from the National Cancer Institute of the National Institutes of Health, which will partially fund its Phase 1/2 safety and anti-cancer efficacy trial in NSCLC (the Grant). Costs entitled to reimbursement under the Grant are accounted for as a reduction to research and development expenses. During the three months ended March 31, 2021, the Company recorded a reduction to research and development expense of $0.3 million for expenses for which it has been reimbursed, or is entitled to reimbursement, under the Grant. The Company has fully

NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS
 

utilized the $1.1 million of available funding under the Grant and did not receive any reimbursement during the three months ended March 31, 2022.

Net loss per share

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

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

	March 31,
	2022		2021
Stock options		5,976,403		5,173,716
Common stock warrants		550,661		550,661
		6,527,064		5,724,377

3.

Fair value measurements

The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

•

Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

•

Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

•

Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

The following table presents the Company’s assets and liabilities that are measured at fair value on a recurring basis (amounts in thousands):

	March 31, 2022
	(Level 1)		(Level 2)		(Level 3)
Assets
Money market funds and U.S. Treasury obligations    (included in cash equivalents)	$	13,362	$	—	$	—

U.S. Treasury obligations		45,945		—		—
Total short-term investments	$	45,945	$	5,413	$	—

There were 0 changes in valuation techniques during the three months ended March 31, 2022. The Company’s short-term investment instruments classified using Level 1 inputs within the fair value hierarchy are classified as such because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The fair value of Level 2 securities is estimated based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term on the assets or liabilities.

Royalty purchase liability

Pursuant to our Amended and Restated Purchase and Sale Agreement (the Royalty Agreement), with Clarus IV Galera Royalty AIV, L.P., Clarus IV-A, L.P., Clarus IV-B, L.P., Clarus IV-C, L.P. and Clarus IV-D, L.P. (collectively, Blackstone or Blackstone Life Sciences), Blackstone agreed to pay up to $80.0 million (the Royalty Purchase Price) in four tranches of $20.0 million each upon the achievement of specific Phase 3 clinical trial patient enrollment milestones. The Company received the first tranche of the Royalty Purchase Price in November 2018, the second tranche of the Royalty Purchase Price in April 2019, and the third tranche of the Royalty Purchase Price in February 2020, in each case in connection with the achievement of the first three milestones, respectively.

In May 2020, the Company entered into Amendment No. 1 to the Royalty Agreement (the Amendment) with Clarus IV Galera Royalty AIV, L.P. (the Blackstone Purchaser). The Blackstone Purchaser is affiliated with Blackstone Life Sciences, the successor in interest to Clarus Ventures. The Amendment increased the Royalty Purchase Price by $37.5 million, to $117.5 million by increasing the fourth tranche from $20.0 million to $37.5 million and adding a new $20.0 million tranche upon the achievement of an additional clinical enrollment milestone. The Company accounted for the Amendment as a debt modification and is amortizing fees paid to the Blackstone Purchaser related to the Amendment over the estimated term of the royalty purchase liability utilizing the effective-interest method. In June 2021, the Company received the new tranche ($20.0 million) under the Amendment in connection with the enrollment of the first patient in a Phase 2b trial of rucosopasem in combination with SBRT in patients with locally advanced pancreatic cancer, which the Company refers to as the GRECO-2 trial. Also in June 2021, the Company completed enrollment in the ROMAN trial, thereby achieving the milestone associated with the fourth tranche ($37.5 million) under the Amendment, which was received in July 2021.

The Company accounts for the Royalty Agreement as a debt instrument. The $117.5 million in proceeds received as of March 31, 2022 have been recorded as a liability on the accompanying consolidated balance sheets. Interest expense is imputed based on the estimated royalty repayment period described below, which takes into consideration the probability and timing of obtaining FDA approval and the potential future revenue from commercializing its product candidates, and which results in a corresponding increase in the liability balance. As the Company continues to evaluate the next steps for its programs focused on the reduction of radiotherapy-induced toxicity, planned or possible next steps may have a material impact on the royalty purchase liability. The Company recognized $2.3 million and $1.3 million in noncash interest expense during the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, the effective interest rate was 7.2%.

Pursuant to the Royalty Agreement and the Amendment, in connection with the payment of each tranche of the Royalty Purchase Price, the Company has agreed to sell, convey, transfer and assign to Blackstone all of its right, title and interest in a high single-digit percentage of (i) worldwide net sales of avasopasem and rucosopasem (collectively, the Products) and (ii) all amounts received by the Company or its affiliates, licensees and sublicensees with respect to Product-related damages (collectively, the Product Payments) during the Royalty Period. The Royalty Period means, on a Product-by-Product and country-by-country basis, the period of time commencing on the commercial launch of such Product in such country and ending on the latest to occur of (i) the 12th anniversary of such commercial launch, (ii) the expiration of all valid claims of the Company’s patents covering such Product in such country, and (iii) the expiration of regulatory data protection or market exclusivity or similar regulatory protection afforded by the health authorities in such country, to the extent such protection or exclusivity effectively prevents generic versions of such Product from entering the market in such country.

The Royalty Agreement and the Amendment will remain in effect until the date on which the aggregate amount of the Product Payments paid to Blackstone exceeds a fixed single-digit multiple of the actual amount of the Royalty Purchase Price received by the Company, unless earlier terminated pursuant to the mutual written agreement of the Company and Blackstone. If no Products are commercialized, the Company would not have an obligation to make Product Payments to Blackstone, which is the sole mechanism for repaying the liability.

Upon execution of the Amendment, the Company issued common stock warrants to the Blackstone Purchaser, each of which became exercisable upon the receipt by the Company of the applicable specified milestone payment. The issued warrants expire six years after the initial exercise dates, as follows:
 

	Shares		Exercise Price		Initial Exercise Date	Expiration Date
New Milestone Warrant		293,686	$	13.62	6/7/2021	6/6/2027
Fourth Milestone Warrant		256,975	$	13.62	7/19/2021	7/18/2027

The warrants are equity-classified and were valued at $4.7 million using the Black-Scholes option pricing model. The warrants were recorded as a discount to the royalty purchase liability. The Company amortizes the debt discount to interest expense over the estimated term of the royalty purchase liability utilizing the effective-interest method.

Equity

Equity offerings

In December 2020, the Company entered into the Sales Agreement with Jefferies LLC (Jefferies) as sales agent, pursuant to which it may, from time to time, issue and sell common stock with an aggregate value of up to $50.0 million in “at-the-market” (ATM) offerings under the Company’s Registration Statement on Form S-3 (File No. 333-251061) filed with the SEC on December 1, 2020. Sales of common stock, if any, pursuant to the Sales Agreement, may be made in sales deemed to be an “at the market offering” as defined in Rule 415(a) of the Securities Act, including sales made directly through the Nasdaq Global Market or on any other existing trading market for the Company’s common stock. The Company is required to pay Jefferies a commission equal to 3 percent of the gross sales proceeds and has provided Jefferies with customary indemnification rights. During the three months ended March 31, 2022, 314,296 shares were sold under the Sales Agreement at a weighted average price per share of $3.70. Net proceeds to the Company after deducting fees, commissions and other expenses related to the offering were approximately $1.1 million for the three months ended March 31, 2022. As of March 31, 2022, there was approximately $40.6 million of available capacity under the Sales Agreement.

Share-based compensation

In connection with the Company’s Initial Public Offering, or IPO, in November 2019, the Company’s board of directors adopted and the Company’s stockholders approved the Galera Therapeutics, Inc. 2019 Incentive Award Plan (the 2019 Plan), which became effective upon the effectiveness of the registration statement on Form S-1 for the IPO. Upon effectiveness of the 2019 Plan, the Company ceased granting new awards under the Prior Plan (as defined herein).

The 2019 Plan provides for the grant of incentive stock options, nonstatutory stock options, restricted stock awards, restricted stock units, stock appreciation rights and other stock-based awards. The number of shares of common stock initially available for issuance under the 2019 Plan was 1,948,970 shares of common stock plus the number of shares subject to awards outstanding under the Prior Plan that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by the Company on or after the effective date of the 2019 Plan. In addition, the number of shares of common stock available for issuance under the 2019 Plan is subject to an annual increase on the first day of each calendar year beginning on January 1, 2020 and ending on and including January 1, 2029 equal to the lesser of (i) 4% of the Company’s outstanding shares of common stock on the final day of the immediately preceding calendar year, and (ii) such smaller number of shares of common stock as determined by the Company’s board of directors. As of March 31, 2022, there were 1,258,494 shares available for future issuance under the 2019 Plan, including 1,058,350 shares added pursuant to this provision effective January 1, 2022. The maximum number of shares of common stock that may be issued under the 2019 Plan upon the exercise of incentive stock options is 14,130,029.

In November 2019, the Company’s board of directors adopted and the Company’s stockholders approved the Galera Therapeutics, Inc. 2019 Employee Stock Purchase Plan (the ESPP). The ESPP allows employees to buy Company stock through after-tax payroll deductions at a discount from market value. The number of shares of common stock initially available for issuance under the ESPP was 243,621 shares of common stock. In addition, the number of shares of common stock available for issuance under the ESPP is subject to an annual increase on the first day of each calendar year beginning on January 1, 2020 and ending on and including January 1, 2029 equal to the lesser of (i) 1% of the Company’s outstanding shares of common stock on the final day of the immediately preceding calendar year and (ii) such smaller number of shares of common stock as determined by the Company’s board of directors, provided that not more than 3,288,886 shares of common stock may be issued under the ESPP. As of March 31, 2022, there were 1,006,084 shares available for issuance under the ESPP, including 264,587 shares added pursuant to this provision effective January 1, 2022.

In November 2012, the Company adopted the Equity Incentive Plan (the Prior Plan). The total number of shares subject to outstanding awards under the Prior Plan as of March 31, 2022 was 2,093,811. NaN shares remain available for issuance under the Prior Plan and no further grants will be made under the Prior Plan; however, the Prior Plan continues to govern awards that are outstanding under it.

The Company’s stock option awards vest based on the terms in the governing agreements and generally vest over four years and have a term of 10 years.

Vested and expected to vest at March 31, 2022		5,976,403		$	7.11		7.4

As of March 31, 2022, the unrecognized compensation cost was $15.8 million and will be recognized over an estimated weighted-average amortization period of 2.6 years. The aggregate intrinsic value of options outstanding and options exercisable as of March 31, 2022 was $0.4 million and $0.3 million, respectively. Options granted during the three months ended March 31, 2022 and 2021 had weighted-average grant-date fair values of $1.71 and $9.00 per share, respectively.

The fair value of options is estimated using the Black-Scholes option pricing model, which takes into account inputs such as the exercise price, the estimated fair value of the underlying common stock at the grant date, expected term, expected stock price volatility, risk-free interest rate and dividend yield. The fair value of stock options during the three months ended March 31, 2022 and 2021 was determined using the methods and assumptions discussed below.

•

The expected term of employee stock options with service-based vesting is determined using the “simplified” method, as prescribed in SEC’s Staff Accounting Bulletin (SAB) No. 107, whereby the expected life equals the arithmetic average of the vesting term and the original contractual term of the option due to the Company’s lack of sufficient historical data. The expected term of nonemployee options is equal to the contractual term.

•

The expected stock price volatility is based on historical volatilities of comparable public entities within the Company’s industry which were commensurate with the expected term assumption as described in SAB No. 107.

•

The risk-free interest rate is based on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period that is commensurate with the expected term.

•

The expected dividend yield is 0% because the Company has not historically paid, and does not expect for the foreseeable future to pay, a dividend on its common stock.

•

The Company’s board of directors has determined the per share value of the Company’s common stock based on the closing price as reported by the NASDAQ Global Market on the date of the grant.

Subsequent events

On May 16, 2022, the Company announced that it intends to file an NDA submission of avasopasem for radiotherapy-induced SOM by the end of 2022 after recent interactions with the FDA. The planned NDA submission for this program may have an impact on the Company's consolidated financial statements, including amounts recorded for the royalty purchase liability, and such impact may be material. Interest expense associated with the royalty purchase liability is imputed based on the estimated royalty repayment period, which takes into consideration the probability and timing of obtaining FDA approval and the potential future revenue from commercializing the Company’s product candidates. The imputed interest expense results in a corresponding increase in the royalty purchase liability.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report on Form 10-Q, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. As a result of many important factors, including those set forth in the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC on March 10, 2022, or the 2021 Form 10-K, and this Quarterly Report on Form 10-Q, our actual results could differ materially from the results described in, or implied, by these forward-looking statements.

Overview

We are a clinical stage biopharmaceutical company focused on developing and commercializing a pipeline of novel, proprietary therapeutics that have the potential to transform radiotherapy in cancer. We leverage our expertise in superoxide dismutase mimetics to design drugs to reduce normal tissue toxicity from radiotherapy and to increase the anti-cancer efficacy of radiotherapy. Avasopasem manganese (GC4419, also referred to as avasopasem) is a highly selective small molecule dismutase mimetic in development for the reduction of severe oral mucositis, or SOM, in patients with head and neck cancer, or HNC, and for the reduction of esophagitis in patients with lung cancer. SOM is a common, debilitating complication of radiotherapy in patients with HNC. In February 2018, the U.S. Food and Drug Administration, or FDA, granted Breakthrough Therapy Designation to avasopasem for the reduction of SOM induced by radiotherapy, with or without systemic therapy. Our second dismutase mimetic product candidate rucosopasem manganese (GC4711, also referred to as rucosopasem), is in clinical-stage development to augment the anti-cancer efficacy of stereotactic body radiation therapy, or SBRT, in patients with non-small cell lung cancer, or NSCLC, and locally advanced pancreatic cancer, or LAPC.

In December 2021, we announced corrected topline efficacy results from a Phase 3 trial of avasopasem for the reduction of radiotherapy-induced SOM in patients with locally advanced HNC, which we refer to as the ROMAN trial. We had previously announced topline results from the ROMAN trial in October 2021. Upon further analysis following the October topline data announcement, an error by the contract research organization was identified in the statistical program. Correction of this error resulted in improved p-values for the primary and secondary endpoints. The corrected results demonstrated efficacy across multiple SOM endpoints with a statistically significant 16% relative reduction on the primary endpoint of reduction in the incidence of SOM (p=0.045) and a statistically significant reduction on the secondary endpoint of number of days of SOM (p=0.002), with a median of 18 days in the placebo arm versus 8 days in the avasopasem arm (56% relative reduction). Exploratory analyses, such as time to SOM onset and SOM incidence at various landmarks of radiotherapy delivered, also demonstrated clinical efficacy of avasopasem in reducing the burden of SOM. Avasopasem appeared to be generally well tolerated compared to placebo. The ROMAN trial is our second randomized trial conducted in patients with HNC to achieve statistical significance and demonstrate improved clinical benefit in reducing SOM. Based on these data, we plan to submit to the FDA a New Drug Application, or NDA, of avasopasem for radiotherapy-induced SOM by the end of 2022.

In December 2021, we also announced topline results from a Phase 2a multi-center trial in Europe assessing the safety and efficacy of avasopasem in patients with HNC undergoing standard-of-care radiotherapy, which we refer to as the EUSOM trial. This trial was conducted in twelve centers across six countries in Europe and enrolled 38 patients, of which 33 completed full treatment. Avasopasem appeared to be generally well tolerated. The incidence of SOM was 54.5% and median number of days of SOM was 9 days in the EUSOM trial, in line with the ROMAN trial in which the incidence of SOM in the avasopasem arm was 54% and the median duration was 8 days.

In May 2022, we announced topline results from an open-label, single-arm Phase 2a trial evaluating avasopasem for its ability to reduce the incidence of radiotherapy-induced esophagitis in patients with lung cancer, which we refer to as the AESOP trial. This multi-center trial enrolled 39 patients (62 screened) of which 35 completed treatment with 60 gray of radiotherapy plus chemotherapy over six weeks. Of these 35 patients, 29 received at least five weeks of 90 mg of avasopasem on the days they underwent radiotherapy. These 29 patients were evaluated as the pre-specified per protocol population. The results demonstrated that avasopasem substantially reduced the incidence of severe esophagitis in patients with lung cancer receiving chemoradiotherapy compared to historical data in the literature. Avasopasem was generally well tolerated. The adverse events experienced are comparable to those expected with chemoradiotherapy.

There are currently no FDA-approved drugs and no established guidelines for the treatment of radiotherapy-induced esophagitis. We may pursue a strategy for avasopasem, if approved for reduction in the incidence of SOM, of presenting the AESOP clinical data to entities like the National Comprehensive Cancer Network, or NCCN, to support the use of avasopasem to reduce

15

esophagitis as a medically accepted indication in published drug compendia, notwithstanding that this indication may not be approved by the FDA.

In addition to developing avasopasem for the reduction of normal tissue toxicity from radiotherapy, we are developing our second dismutase mimetic product candidate, rucosopasem, to increase the anti-cancer efficacy of higher daily doses of radiotherapy, or SBRT. In September 2021, in support of rucosopasem, we also announced final results from our pilot Phase 1/2 safety and anti-cancer efficacy trial of avasopasem in combination with SBRT in patients with unresectable or borderline resectable LAPC. The results included a minimum follow up of one year on all 42 patients enrolled in the trial and were consistent with the positive interim results reported with a minimum follow up of six months. In this proof-of-concept trial, relative improvements were observed in overall survival, progression-free survival, local tumor control and time to distant metastases. 46% of patients in the active arm were alive at last follow-up (11 out of 24) compared to 33% in the placebo arm (6 out of 18). As previously reported, 29% of patients in the active arm achieved a 30% or greater decrease in primary tumor size (partial response) compared to 11% of patients in the placebo arm. Avasopasem was well tolerated, with similar rates of early and late adverse events in the active and placebo arms.

We used our observations from the pilot LAPC trial of avasopasem to inform the design of our rucosopasem clinical trials in combination with SBRT. We have successfully completed Phase 1 trials of intravenous rucosopasem in healthy volunteers and initiated a Phase 1/2 trial in patients with NSCLC in October 2020, which we refer to as the GRECO-1 trial. The GRECO-1 trial is supported in part by a Small Business Innovation Research grant from the National Cancer Institute of the National Institutes of Health for the investigation of our dismutase mimetics in combination with SBRT for the treatment of lung cancer. We intend for this trial to assess the anti-cancer efficacy and safety of rucosopasem in combination with SBRT. We expect to report initial data from this trial in the first half of 2022. We initiated a Phase 2b trial of rucosopasem in combination with SBRT in patients with LAPC in May 2021, which we refer to as the GRECO-2 trial. In the future, we intend to assess the anti-cancer efficacy and safety of rucosopasem in combination with SBRT and a checkpoint inhibitor.

Since our inception, we have devoted substantially all of our resources to organizing and staffing our company, business planning, raising capital, acquiring and developing product and technology rights, and conducting research and development. We have incurred recurring losses and negative cash flows from operations and have funded our operations primarily through the sale and issuance of equity and proceeds received under the Amended and Restated Purchase and Sale Agreement, which we refer to as the Royalty Agreement, with Clarus IV Galera Royalty AIV, L.P., Clarus IV-A, L.P., Clarus IV-B, L.P., Clarus IV-C, L.P. and Clarus IV-D, L.P., or collectively, Blackstone or Blackstone Life Sciences (formerly known as Clarus Ventures).

Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of our current or future product candidates. Our net loss was $80.5 million and $74.2 million for the years ended December 31, 2021 and 2020, respectively, and $15.4 million for the three months ended March 31, 2022. As of March 31, 2022, we had $60.9 million in cash, cash equivalents and short-term investments and an accumulated deficit of $331.5 million. We expect to continue to incur significant expenses and operating losses for the foreseeable future as we operate as a public company, advance our product candidates through all stages of development and clinical trials, build our commercial infrastructure and, ultimately, seek regulatory approval of our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution.

As a result, we will need to raise substantial additional capital to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we plan to finance our operations through the sale of equity, debt financings or other capital sources, which may include collaborations with other companies or other strategic transactions. There is no assurance that we will be successful in obtaining an adequate level of financing as and when needed to finance our operations on terms acceptable to us or at all. If we are unable to secure adequate additional funding as and when needed, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more product candidates or delay our pursuit of potential in-licenses or acquisitions.

Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

We expect our existing cash, cash equivalents and short-term investments as of March 31, 2022 will enable us to fund our operating expenses and capital expenditure requirements into the second half of 2023.

Business Update Regarding COVID-19

The current COVID-19 pandemic continues to present a substantial public health and economic challenge around the world and is affecting our employees, communities, clinical trial sites and business operations, as well as the U.S. economy and international financial markets. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition will depend on future developments that are highly uncertain and cannot be accurately predicted, including new information that may emerge concerning COVID-19, the actions taken to contain it or treat its impact, including the effectiveness of vaccines and vaccine distribution efforts, the impact of new variants of COVID-19 and the economic impact on local, regional, national and international markets. See “Risk Factors—Other Risks Related to Our Business—The COVID-19 pandemic has adversely impacted and could continue to adversely impact our business, including our preclinical studies and clinical trials, results of operations and financial condition” in Part I, Item 1A of the 2021 Form 10-K.

Mitigation activities to minimize COVID-19-related operation disruptions are ongoing given the severity and evolving nature of the situation, and we are continuing to monitor the impact of the COVID-19 pandemic on our operations and ongoing clinical development activity.

Our third-party contract manufacturing partners continue to operate at or near normal levels. While we currently do not anticipate any material interruptions in our clinical trial supply or manufacturing scale-up activities, it is possible that the COVID-19 pandemic and response efforts may have an impact in the future on our third-party suppliers and contract manufacturing partners' ability to manufacture our clinical trials supply or progress manufacturing scale-up activities.

We have also implemented measures designed to protect the health and safety of our workforce.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those described below. We base our estimates on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Our critical accounting policies are described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies” in the 2021 Form 10-K and the notes to the unaudited interim consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q. During the three months ended March 31, 2022 there were no material changes to our critical accounting policies from those discussed in the 2021 Form 10-K.

Components of Results of Operations

Research and Development Expense

Research and development expenses consist primarily of costs 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 to conduct the necessary preclinical studies and clinical trials required to obtain regulatory approval;

•

personnel expenses, including salaries, benefits and share-based compensation expense for employees engaged in research and development functions;

•

costs of funding research performed by third parties, including pursuant to agreements with contract research organizations, or CROs, as well as investigative sites and consultants that conduct our preclinical studies and clinical trials;

•

expenses incurred under agreements with contract manufacturing organizations, or CMOs, including manufacturing scale-up expenses and the cost of acquiring and manufacturing preclinical study and clinical trial materials;

17

•

fees paid to consultants who assist with research and development activities;

•

expenses related to regulatory activities, including filing fees paid to regulatory agencies; and

•

allocated expenses for facility costs, including rent, utilities, depreciation and maintenance.

We track our external research and development expenses on a program-by-program basis, such as fees paid to CROs, CMOs and research laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. However, we do not track our internal research and development expenses on a program-by-program basis as they primarily relate to personnel-related and share-based compensation expense, early-stage research expenses and other costs that are deployed across multiple projects under development.

The following table summarizes our research and development expenses by program for the three months ended March 31, 2022 and 2021 (in thousands):

	Three months ended March 31,
	2022		2021
Avasopasem manganese (GC4419)	$	2,396	$	7,331
Rucosopasem manganese (GC4711)		2,524		920
Other research and development expense		554		1,556
Personnel related and share-based compensation    expense		2,633		2,616
	$	8,107	$	12,423

Research and development activities are central to our business model. Product candidates in later stages of clinical development, such as avasopasem, generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. Our research and development expenses may increase over the next several years as we increase personnel costs, including stock-based compensation, conduct our later-stage clinical trials for avasopasem and rucosopasem, if applicable, conduct other clinical trials for current and future product candidates and prepare regulatory filings for our product candidates.

The successful development of our 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 our product candidates, including the significant costs associated with our ongoing and planned clinical trials, which likely will vary significantly as a result of many factors, including:

•

delays in regulators or institutional review boards authorizing us or our investigators to commence our clinical trials, or in our ability to negotiate agreements with clinical trial sites or CROs;

•

our ability to secure adequate supply of our product candidates for our trials;

•

the number of clinical sites included in the trials;

•

the ability and 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;

•

any side effects associated with our product candidates;

•

the duration of patient follow-up;

•

the results of our clinical trials;

•

significant and changing government regulations; and

18

•

the impact of unforeseen events, such as the COVID-19 pandemic, on the initiation and completion of our preclinical studies, clinical trials and manufacturing scale-up.

Our research and development expenditures are subject to additional uncertainties, including the terms and timing of regulatory approvals. We may never succeed in achieving regulatory approval for our product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of our product candidates. A change in the outcome of any of these variables with respect to the development of a product candidate could result in a significant change in the costs of 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.

General and Administrative Expense

General and administrative expense consists primarily of personnel expenses, including salaries, benefits and share-based compensation expense for employees in executive, finance, accounting, legal, information technology, commercial, business development and human resource functions. General and administrative expense also includes corporate facility costs, including rent, utilities, depreciation and maintenance, not otherwise included in research and development expense, as well as legal fees related to intellectual property and corporate matters and fees for accounting and consulting services.

We expect that our general and administrative expense will increase in the future to support our continued research and development activities, potential commercialization efforts, and to expand our operations and organizational capabilities. These increases will likely include increased costs related to the hiring of additional personnel, fees to outside consultants, lawyers and accountants and expenses related to services associated with maintaining compliance with the requirements of Nasdaq and the SEC, insurance and investor relations costs. Should we commercialize our product candidates, we expect to incur significantly increased expenses associated with building our commercial infrastructure.

Interest Income

Interest income consists of amounts earned on our cash and cash equivalents held with large institutional banks, U.S. Treasury obligations and a money market mutual fund invested in U.S. Treasury obligations, and our short-term investments in U.S. Treasury and government agency obligations.

Interest Expense

Interest expense consists of non-cash interest on proceeds received under the Royalty Agreement with Blackstone and non-cash interest expense associated with the amortization of the debt discount recorded for the Blackstone warrants.

Net Operating Loss and Research and Development Tax Credit Carryforwards

As of December 31, 2021, we had federal and state tax net operating loss carryforwards of $145.3 million and $167.3 million, respectively. We also had foreign net operating loss carryforwards of $1.5 million. All foreign net operating losses and approximately $82.7 million of federal net operating losses are available to be carried forward indefinitely. The remaining federal net operating losses and all state net operating losses begin to expire in 2032 unless previously utilized. As of December 31, 2021, we also had federal and state research and development tax credit carryforwards of $6.1 million and foreign research and development tax credit carryforwards of $1.6 million. The federal and state research and development tax credit carryforwards will begin to expire in 2032 and 2036, respectively, unless previously utilized. The foreign research and development tax credit carryforwards do not have an expiration date.

Utilization of the federal and state net operating losses and credits may be subject to a substantial annual limitation. The annual limitation may result in the expiration of our net operating losses and credits before we can use them. We have recorded a valuation allowance on substantially all of our deferred tax assets, including our deferred tax assets related to our net operating loss and research and development tax credit carryforwards, given the current uncertainty over our ability to utilize such amounts.

Results of Operations

Comparison of the Three Months Ended March 31, 2022 and 2021

The following table sets forth our results of operations for the three months ended March 31, 2022 and 2021 (in thousands):

	Three months ended March 31,
	2022			2021			Change
Operating expenses:
Research and development	$	8,107		$	12,423		$	(4,316	)
General and administrative		5,047			5,058			(11	)
Loss from operations		(13,154	)		(17,481	)		4,327
Other income (expense):
Interest income		14			19			(5	)
Interest expense		(2,303	)		(1,253	)		(1,050	)
Net loss	$	(15,443	)	$	(18,715	)	$	3,272

Research and Development Expense

Research and development expense decreased by $4.3 million from $12.4 million for the three months ended March 31, 2021 to $8.1 million for the three months ended March 31, 2022. Avasopasem development costs decreased by $4.9 million due to decreased expenses for clinical trials, as the ROMAN, EUSOM and AESOP trials completed enrollment in 2021, and decreased manufacturing expenses. Other research and development expenses decreased by $1.0 million, principally due to decreased costs for independent contractors and consultants and decreased costs for development of additional product candidates. Partially offsetting these decreases, rucosopasem development costs increased by $1.6 million, due principally to increased expenses in our GRECO trials.

General and Administrative Expense

General and administrative expense remained consistent year over year, with a decrease of $11,000 from the three months ended March 31, 2021 compared to the three months ended March 31, 2022.

Interest Income

Interest income decreased from $19,000 for the three months ended March 31, 2021 to $14,000 for the three months ended March 31, 2022 due to lower average invested cash balances.

Interest Expense

We recognized $2.3 million and $1.3 million in non-cash interest expense during the three months ended March 31, 2022 and 2021, respectively, in connection with the Royalty Agreement with Blackstone Life Sciences. The increase is primarily attributable to interest on the $57.5 million in milestone payments received in June and July 2021.

Liquidity and Capital Resources

We do not currently have any approved products and have never generated any revenue from product sales. Through March 31, 2022, we have funded our operations primarily through the sale and issuance of equity and $117.5 million of proceeds received under the Royalty Agreement with Blackstone Life Sciences, receiving aggregate gross proceeds of $340.0 million. In November 2019, we completed our IPO, which resulted in the issuance and sale of 5,000,000 shares of common stock at a public offering price of $12.00 per share, generating net proceeds of $53.0 million after deducting underwriting discounts and other offering costs. On December 9, 2019, in connection with the partial exercise of the over-allotment option granted to the underwriters of our IPO, 445,690 additional shares of common stock were sold at the IPO price of $12.00 per share, generating net proceeds of approximately $5.0 million after deducting underwriting discounts and other offering costs.

In December 2020, we entered into an Open Market Sale Agreement, or the Sales Agreement, with Jefferies LLC, or Jefferies, as sales agent, pursuant to which we may, from time to time, issue and sell common stock with an aggregate value of up to

20

$50.0 million in “at-the-market,” or ATM, offerings under our Registration Statement on Form S-3 (File No. 333-251061) filed with the SEC on December 1, 2020. Sales of common stock, if any, pursuant to the Sales Agreement, may be made in sales deemed to be an “at the market offering” as defined in Rule 415(a) of the Securities Act, including sales made directly through the Nasdaq Global Market or on any other existing trading market for our common stock. During the three months ended March 31, 2022, we sold an aggregate 314,296 shares of our common stock under this Sales Agreement, at a weighted average price per share of $3.70, generating aggregate net proceeds of $1.1 million, after deducting fees, commissions and other expenses. As of March 31, 2022, there was $40.6 million of common stock remaining available for sale under the Sales Agreement.

As of March 31, 2022, we had $60.9 million in cash, cash equivalents and short-term investments and an accumulated deficit of $331.5 million. We have no ongoing material financing commitments, such as lines of credit or guarantees, that are expected to affect our liquidity over the next five years.

Cash Flows

The following table shows a summary of our cash flows for the periods indicated (in thousands):

	Three months ended March 31,
	2022			2021
Net cash used in operating activities	$	(11,385	)	$	(15,303	)
Net cash provided by investing activities		9,996			12,883
Net cash provided by financing activities		1,175			235
Net decrease in cash and cash equivalents	$	(214	)	$	(2,185	)

Operating Activities

During the three months ended March 31, 2022, we used $11.4 million of net cash in operating activities. Cash used in operating activities reflected our net loss of $15.4 million and $0.2 million from changes in operating assets and liabilities, partially offset by non-cash charges of $4.2 million related to share-based compensation, interest expense on our Royalty Agreement with Blackstone Life Sciences and depreciation expense. The primary use of cash was to fund our operations related to the development of our product candidates.

During the three months ended March 31, 2021, we used $15.3 million of net cash in operating activities. Cash used in operating activities reflected our net loss of $18.7 million, partially offset by non-cash charges of $3.1 million related to share-based compensation, interest expense on our Royalty Agreement with Blackstone Life Sciences and depreciation expense. The primary use of cash was to fund our operations related to the development of our product candidates.

Investing Activities

During the three months ended March 31, 2022, investing activities provided $10.0 million in cash proceeds from the net sales of our short-term investments.

During the three months ended March 31, 2021, investing activities provided $12.9 million in net cash proceeds, primarily attributable to $13.1 million in net sales of our short-term investments, partially offset by $0.2 million for the purchase of property and equipment.

Financing Activities

During the three months ended March 31, 2022, financing activities provided $1.2 million from the sale of our common stock under the Sales Agreement with Jefferies and the exercise of stock options.

During the three months ended March 31, 2021, financing activities provided $0.2 million from the exercise of stock options.

Funding Requirements

Our operating expenses increased substantially in 2020 and 2021, and our expenses may continue to increase in connection with our ongoing activities, particularly as we continue the research and development of, continue or initiate clinical trials

21

of, and seek marketing approval for, our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Furthermore, we expect to continue to incur significant costs associated with operating as a public company. Accordingly, we would need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts.

We expect our existing cash, cash equivalents and short-term investments as of March 31, 2022 will enable us to fund our operating expenses and capital expenditure requirements into the second half of 2023.

Because of the numerous risks and uncertainties associated with research, development and commercialization of product candidates, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on, and could increase significantly as a result of, many factors, including:

•

the direct and indirect impact of COVID-19 on our business and operations;

•

the scope, progress, results and costs of preclinical studies and clinical trials;

•

the scope, prioritization and number of our research and development programs;

•

the costs, timing and outcome of regulatory review of our product candidates;

•

our ability to establish and maintain collaborations on favorable terms, if at all;

•

the extent to which we are obligated to reimburse, or entitled to reimbursement of, clinical trial costs under collaboration agreements, if any;

•

the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

•

the extent to which we acquire or in-license other product candidates and technologies;

•

the costs of securing manufacturing arrangements for commercial production; and

•

the costs of scaling-up or contracting for sales and marketing capabilities as we prepare for the potential commercialization of our product candidates.

Identifying potential product candidates and conducting preclinical studies and clinical trials is a time-consuming, expensive and uncertain process that takes many years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of product candidates that we do not expect to be commercially available for the next couple of years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all. For example, the trading prices for our and other biopharmaceutical companies’ stock have been highly volatile as a result of the COVID-19 pandemic. As a result, we may face difficulties raising capital through sales of our common stock and any such sales may be on unfavorable terms. See “Risk Factors” in Part I, Item 1A of the 2021 Form 10-K.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our shareholders’ ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our existing stockholders’ rights. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay,

22

limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Royalty Agreement with Blackstone Life Sciences (Formerly Known as Clarus Ventures)

In November 2018, we entered into the Royalty Agreement with Blackstone Life Sciences. Pursuant to the Royalty Agreement, Blackstone agreed to pay us, in the aggregate, up to $80.0 million, or the Royalty Purchase Price, in four tranches of $20.0 million each upon the achievement of specified clinical milestones in our ROMAN trial. We agreed to apply the proceeds from such payments primarily to support clinical development and regulatory activities for avasopasem, rucosopasem and any pharmaceutical product comprising or containing avasopasem or rucosopasem, or, collectively, the Products, as well as to satisfy working capital obligations and for general corporate expenses. We received the first tranche of the Royalty Purchase Price in November 2018, the second tranche of the Royalty Purchase Price in April 2019, and the third tranche of the Royalty Purchase Price in February 2020, in each case in connection with the achievement of the first three milestones, respectively, under the Royalty Agreement.

In May 2020, we entered into Amendment No. 1 to the Royalty Agreement, or the Amendment, with Clarus IV Galera Royalty AIV, L.P., or the Blackstone Purchaser. The Blackstone Purchaser is affiliated with Blackstone Life Sciences, successor in interest to Clarus Ventures. The Amendment increased the Royalty Purchase Price by $37.5 million to $117.5 million by increasing the fourth tranche from $20.0 million to $37.5 million and adding a new $20.0 million tranche upon the achievement of an additional clinical enrollment milestone. We received the new $20.0 million tranche of the Amendment in June 2021, in connection with the enrollment of the first patient in the GRECO-2 trial. Also in June 2021, we completed enrollment in the ROMAN trial, thereby achieving the milestone associated with the fourth tranche, and received the associated $37.5 million in July 2021.

Pursuant to the amended Royalty Agreement, in connection with the payment of each tranche of the Royalty Purchase Price, we have agreed to sell, convey, transfer and assign to Blackstone all of our right, title and interest in a high single-digit percentage of (i) worldwide net sales of the Products and (ii) all amounts received by us or our affiliates, licensees and sublicensees with respect to Product-related damages (collectively, the Product Payments) during the Royalty Period. The Royalty Period means, on a Product-by-Product and country-by-country basis, the period of time commencing on the commercial launch of such Product in such country and ending on the latest to occur of (i) the 12th anniversary of such commercial launch, (ii) the expiration of all valid claims of our patents covering such Product in such country, and (iii) the expiration of regulatory data protection or market exclusivity or similar regulatory protection afforded by the health authorities in such country, to the extent such protection or exclusivity effectively prevents generic versions of such Product from entering the market in such country.

The amended Royalty Agreement will remain in effect until the date on which the aggregate amount of the Product Payments paid to Blackstone exceeds a fixed single-digit multiple of the actual amount of the Royalty Purchase Price received by us, unless earlier terminated pursuant to the mutual written agreement of us and Blackstone. If no Products are commercialized, we would not have an obligation to make Product Payments to Blackstone, which is the sole mechanism for repaying the liability.

In May 2020, as partial consideration for the Amendment, we issued two warrants to the Blackstone Purchaser to purchase an aggregate of 550,661 shares of our common stock at an exercise price equal to $13.62 per share, each of which became exercisable upon the receipt by Galera of the applicable specified milestone payment. The issued warrants expire six years after the initial exercise date of each respective warrant.

Recent Accounting Pronouncements

See Note 2 to our interim consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for a description of recent accounting pronouncements applicable to our consolidated financial statements.

JOBS Act Transition Period

In April 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. However, we have chosen to opt out of such extended transition period and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Our decision to opt out of the extended transition period for complying with new or revised accounting standards is irrevocable. However, we may take advantage of the other exemptions discussed below.

Subject to certain conditions, as an emerging growth company we may rely on certain exemptions and reduced reporting requirements, including, without limitation, (1) not being required to provide an auditor’s attestation report on our system of internal

23

control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (2) not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an emerging growth company until the earlier to occur of (a) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more, (b) the last day of the fiscal year following the fifth anniversary of the date of the completion of our IPO (December 31, 2024), (c) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years, or (d) the date on which we are deemed to be a large accelerated filer under the rules of the SEC, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are a smaller reporting company as defined in Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this Item 3.

Item 4. Controls and Procedures.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2022.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the quarter ended March 31, 2022 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
