Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization and description of business | 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 (avasopasem, or GC4419) 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. The Company is also exploring the potential for avasopasem to reduce cisplatin-induced kidney damage. The U.S. Food and Drug Administration (FDA) has granted Fast Track and Breakthrough Therapy designations to avasopasem for the reduction of SOM induced by radiotherapy. In February 2023, the FDA accepted and granted Priority Review designation to the Company's New Drug Application (NDA) for avasopasem for this indication. Galera’s second dismutase mimetic product candidate, rucosopasem manganese (rucosopasem, or GC4711), 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 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 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, with a median of 18 days in the placebo arm versus 8 days in the avasopasem arm. The Company had previously announced topline results from the ROMAN trial in October 2021 that incorrectly stated the reduction on the primary endpoint was not statistically significant. Upon further analysis, an error by the contract research organization was identified in the statistical program. Correction of this error yielded the correct, statistically significant p-values for the primary and a key secondary endpoint. Exploratory analyses, such as time to SOM onset and SOM incidence at various landmarks of radiotherapy delivered, further demonstrated the potential clinical utility of avasopasem in reducing the burden of SOM. Avasopasem appeared to be generally well tolerated compared to placebo. The ROMAN trial is the Company’s second randomized, placebo-controlled trial conducted in patients with HNC to achieve statistical significance and demonstrate clinical benefit in reducing SOM. In December 2022, the Company submitted an NDA to the FDA for avasopasem for radiotherapy-induced SOM in patients with HNC undergoing standard-of-care treatment. The NDA is supported by the data from the two randomized, double-blinded, placebo-controlled trials (ROMAN and Phase 2b GT-201), as well as data from other clinical trials of avasopasem in the proposed indication. In February 2023, the FDA accepted the NDA and granted priority review with a Prescription Drug User Fee Act (PDUFA) target date of August 9, 2023. The FDA indicated in its acceptance of filing letter that it is not planning to hold an advisory committee meeting on the application. 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 $ 396.0 million as of March 31, 2023. 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 follows the provisions of Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 205-40, Presentation of Financial Statements—Going Concern , which requires management to assess the Company’s ability to continue as a going concern for one year after the date the financial statements are issued. The Company expects its existing cash, cash equivalents and short-term investments as of March 31, 2023 will enable the Company to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2023, but not for more than one year after the date of the filing of this Quarterly Report on Form 10-Q, and therefore management has concluded that substantial doubt exists about the Company’s ability to continue as a going concern. Management’s plans to mitigate this risk include raising additional capital through equity or debt financings, or through strategic transactions. Management’s plans may also include the deferral of certain operating expenses unless and until additional capital is received. However, there can be no assurance that the Company will be successful in raising additional capital or that such capital, if available, will be on terms that are acceptable to the Company, or that the Company will be successful in deferring certain operating expenses. If the Company is unable to raise sufficient additional capital or defer sufficient operating expenses, the Company may be compelled to reduce the scope of its operations and planned capital expenditures. 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. The interim consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the continuity of operations, the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. 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. No securities were issued pursuant to the Sales Agreement during the three months ended March 31, 2023. As of March 31, 2023 , there remained $ 37.8 million available under the Sales Agreement. On February 17, 2023, the Company completed a registered direct offering, which resulted in the issuance and sale of 14,320,000 shares of its common stock and warrants to purchase up to 14,320,000 shares of common stock at a combined offering price of $ 2.095 per share and accompanying warrant, generating gross proceeds of $ 30.0 million. The warrants have an exercise price of $ 1.97 per share of common stock, are exercisable immediately following their issuance and will expire five years from the date of issuance. The Company received net proceeds of $ 27.6 million from this offering, after deducting placement agent fees and offering expenses. |

Accounting Policies [Abstract] | |
Basis of Presentation and Significant Accounting Policies | 2. 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, 2022 and 2021 included in the Company’s annual report on Form 10-K filed with the SEC on March 8, 2023 have not materially changed, except as set forth below. 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, 2023 and its results of operations for the three months ended March 31, 2023 and 2022, and statements of changes in stockholder’s equity (deficit) and cash flows for the three months ended March 31, 2023 and 2022. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023, 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, 2022 , included in the Company’s annual report on Form 10-K and filed with the SEC on March 8, 2023. 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. Cash and cash equivalents The Company considers all highly liquid investments that have maturities of three months or less when acquired to be cash equivalents. Cash and cash equivalents as of March 31, 2023 and December 31, 2022 consisted of bank deposits, U.S. Treasury obligations, U.S. government agency securities, and a money market mutual fund invested in U.S. Treasury obligations. We maintain a portion of our cash and cash equivalents in accounts with major financial institutions, and our deposits at these institutions exceed insured limits. Restricted cash Restricted cash represents collateral provided under a commercial credit card agreement entered into with TD Bank, N.A. during July 2022. Restricted cash was $ 50,000 as of March 31, 2023. The Company has recorded this deposit and accumulated interest thereon as restricted cash on its consolidated balance sheet. Refundable PDUFA fee In December 2022, the Company paid a $ 3.2 million PDUFA fee to the FDA in conjunction with the filing of its NDA for avasopasem. The Company requested and has been granted a small business waiver of this PDUFA fee from the FDA, and the amount has been recorded as a Refundable PDUFA fee on the Company’s consolidated balance sheet, as a refund is expected in 2023. 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. Net loss per share Basic loss per share of common stock is computed by dividing net loss 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, 2023 2022 Stock options 7,269,032 5,976,403 Common stock warrants 14,870,661 550,661 22,139,693 6,527,064 Recent Accounting Pronouncements In August 2020, FASB issued ASU 2020-06, “Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it also simplifies the diluted earnings per share calculation in certain areas. This guidance is effective for fiscal years beginning after December 15, 2023, including interim periods therein. Early adoption is permitted. The Company adopted this ASU on January 1, 2023. There is no impact to the Company's consolidated financial statements. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 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, 2023 (Level 1) (Level 2) (Level 3) Assets Cash equivalents Money market funds and U.S. Treasury obligations $ 14,880 $ — $ — U.S. government agency securities — 9,732 — Total cash equivalents $ 14,880 $ 9,732 $ — Short-term investments U.S. government agency securities $ — $ 17,337 $ — U.S. Treasury obligations 4,727 — — Total short-term investments $ 4,727 $ 17,337 $ — December 31, 2022 (Level 1) (Level 2) (Level 3) Assets Money market funds and U.S. Treasury obligations $ 3,467 $ — $ — Short-term investments U.S. government agency securities $ — $ 8,172 $ — U.S. Treasury obligations 19,159 — — Total short-term investments $ 19,159 $ 8,172 $ — There were no changes in valuation techniques during the three months ended March 31, 2023 . 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 [Abstract] | |
Royalty Purchase Liability | 6. 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, 2023 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. The Company updated the assumptions underlying the calculation of interest expense on the royalty purchase liability based on the FDA acceptance of the Company's NDA in February 2023 with Priority Review designation. The Company recogni zed $ 4.2 million and $ 2.3 million in noncash interest expense during the three months ended March 31, 2023 and 2022, respectively. As of March 31, 2023 , the effective interest rate was 12.3 %. 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 [Abstract] | |
Equity | 8. Equity Equity offerings In February 2023, the Company completed a registered direct offering, which resulted in the issuance and sale of 14,320,000 shares of its common stock and warrants to purchase up to 14,320,000 shares of common stock at a combined offering price of $ 2.095 per share and accompanying warrant, and received net proceeds of $ 27.6 million after deducting placement agent fees and offering expenses. The warrants are equity-classified, have an exercise price of $ 1.97 per share of common stock, are exercisable immediately following their issuance, and will expire five years from the date of issuance. 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 three percent of the gross sales proceeds and has provided Jefferies with customary indemnification rights. No securities were issued pursuant to the Sales Agreement during the three months ended March 31, 2023. As of March 31, 2023 , there was $ 37.8 million of available capacity under the Sales Agreement. Share-based compensation Equity Incentive Plan In November 2012, the Company adopted the Galera Therapeutics, Inc. Equity Incentive Plan (the Prior Plan). The Prior Plan provided for the grant of incentive stock options, nonstatutory stock options, restricted stock awards, and stock appreciation rights. In connection with the adoption of the 2019 Plan (as defined below), the Company ceased issuing awards under the Prior Plan. As a result, no shares remain available for issuance under the Prior Plan; however, the Prior Plan continues to govern awards that are outstanding under it. The total number of shares subject to outstanding awards under the Prior Plan as of March 31, 2023 wa s 1,714,906 . 2019 Incentive Award Plan 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. 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, 2023 , there were 1,007,332 shares available for future issuance under the 2019 Plan, including 1,140,402 shares added pursuant to this provision effective January 1, 2023. 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, 2023 , there were 1,291,184 shares available for issuance under the ESPP, including 285,100 shares added pursuant to this provision effective January 1, 2023. 2023 Employment Inducement Award Plan On April 28, 2023, the Board of Directors adopted the Galera Therapeutics, Inc. 2023 Employment Inducement Award Plan (Inducement Plan), which became effective on such date without stockholder approval pursuant to Rule 5635(c)(4) of The Nasdaq Stock Market LLC listing rules (“Rule 5635(c)(4)”). The Inducement Plan provides for the grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, and other stock-based awards. In accordance with Rule 5635(c)(4), awards under the Inducement Plan may only be granted to persons who (a) were not previously an employee or director of the Company, or (b) are commencing employment with the Company following a bona fide period of non-employment, in either case as an inducement material to the individual’s entering into employment with the Company. A total of 1,500,000 shares of common stock was reserved for issuance under the Inducement Plan. Any shares subject to awards previously granted under the Inducement Plan that expire, terminate or are otherwise surrendered, canceled, or forfeited, in a manner that results in the Company (i) acquiring the shares covered by the award at a price not greater than the price (as adjusted to reflect any equity restructuring) paid by the participant for such shares or (ii) not issuing any shares covered by the award, the unused shares covered by such awards will again be available for award grants under the Inducement Plan. Share-based Compensation Share-based compensation expense was as follows for the three months ended March 31, 2023 and 2022 (in thousands): Three months ended 2023 2022 Research and development $ 452 $ 661 General and administrative 1,006 1,187 $ 1,458 $ 1,848 The following table summarizes the activity related to stock option grants for the three months ended March 31, 2023: Shares Weighted Weighted- Outstanding at January 1, 2023 5,783,185 $ 6.86 6.8 Granted 1,784,700 1.78 Exercised ( 76,767 ) 2.39 Forfeited ( 222,086 ) 8.14 Outstanding at March 31, 2023 7,269,032 $ 5.62 7.6 Vested and exercisable at March 31, 2023 3,588,547 $ 7.42 6.1 Vested and expected to vest at March 31, 2023 7,269,032 $ 5.62 7.6 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 . As of March 31, 2023, the unrecognized compensation cos t was $ 10.6 million and will be recognized over an estimated weighted-average amortization period of 2.4 years. The aggregate intrinsic value of options outstanding and of options exercisable as of March 31, 2023 were $ 2.3 million and $ 0.3 million, respectively. Options granted during the three months ended March 31, 2023 and 2022 had weighted-average grant-date fair values of $ 1.41 and $ 1.71 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, 2023 and 2022 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. The grant date fair value of each option grant was estimated throughout the three months ended March 31, 2023 and 2022 using the Black-Scholes option-pricing model using the following weighted-average assumptions: Three months ended 2023 2022 Expected term (in years) 6.2 6.3 Expected stock price volatility 94.9 % 92.4 % Risk-free interest rate 4.13 % 1.74 % Expected dividend yield 0 % 0 % |

Liquidity | Liquidity The Company has incurred recurring losses and negative cash flows from operations since inception and has an accumulated deficit of $ 396.0 million as of March 31, 2023. 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 follows the provisions of Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 205-40, Presentation of Financial Statements—Going Concern , which requires management to assess the Company’s ability to continue as a going concern for one year after the date the financial statements are issued. The Company expects its existing cash, cash equivalents and short-term investments as of March 31, 2023 will enable the Company to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2023, but not for more than one year after the date of the filing of this Quarterly Report on Form 10-Q, and therefore management has concluded that substantial doubt exists about the Company’s ability to continue as a going concern. Management’s plans to mitigate this risk include raising additional capital through equity or debt financings, or through strategic transactions. Management’s plans may also include the deferral of certain operating expenses unless and until additional capital is received. However, there can be no assurance that the Company will be successful in raising additional capital or that such capital, if available, will be on terms that are acceptable to the Company, or that the Company will be successful in deferring certain operating expenses. If the Company is unable to raise sufficient additional capital or defer sufficient operating expenses, the Company may be compelled to reduce the scope of its operations and planned capital expenditures. 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. The interim consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the continuity of operations, the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. 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. No securities were issued pursuant to the Sales Agreement during the three months ended March 31, 2023. As of March 31, 2023 , there remained $ 37.8 million available under the Sales Agreement. On February 17, 2023, the Company completed a registered direct offering, which resulted in the issuance and sale of 14,320,000 shares of its common stock and warrants to purchase up to 14,320,000 shares of common stock at a combined offering price of $ 2.095 per share and accompanying warrant, generating gross proceeds of $ 30.0 million. The warrants have an exercise price of $ 1.97 per share of common stock, are exercisable immediately following their issuance and will expire five years from the date of issuance. The Company received net proceeds of $ 27.6 million from this offering, after deducting placement agent fees and offering expenses. |
Basis of Presentation and Consolidation | 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, 2023 and its results of operations for the three months ended March 31, 2023 and 2022, and statements of changes in stockholder’s equity (deficit) and cash flows for the three months ended March 31, 2023 and 2022. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023, 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, 2022 , included in the Company’s annual report on Form 10-K and filed with the SEC on March 8, 2023. |
Use of Estimates | 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. |
Cash and cash equivalents | Cash and cash equivalents The Company considers all highly liquid investments that have maturities of three months or less when acquired to be cash equivalents. Cash and cash equivalents as of March 31, 2023 and December 31, 2022 consisted of bank deposits, U.S. Treasury obligations, U.S. government agency securities, and a money market mutual fund invested in U.S. Treasury obligations. We maintain a portion of our cash and cash equivalents in accounts with major financial institutions, and our deposits at these institutions exceed insured limits. |
Restricted cash | Restricted cash Restricted cash represents collateral provided under a commercial credit card agreement entered into with TD Bank, N.A. during July 2022. Restricted cash was $ 50,000 as of March 31, 2023. The Company has recorded this deposit and accumulated interest thereon as restricted cash on its consolidated balance sheet. Refundable PDUFA fee In December 2022, the Company paid a $ 3.2 million PDUFA fee to the FDA in conjunction with the filing of its NDA for avasopasem. The Company requested and has been granted a small business waiver of this PDUFA fee from the FDA, and the amount has been recorded as a Refundable PDUFA fee on the Company’s consolidated balance sheet, as a refund is expected in 2023. |
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. |
Net Loss Per Share | Net loss per share Basic loss per share of common stock is computed by dividing net loss 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, 2023 2022 Stock options 7,269,032 5,976,403 Common stock warrants 14,870,661 550,661 22,139,693 6,527,064 |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In August 2020, FASB issued ASU 2020-06, “Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it also simplifies the diluted earnings per share calculation in certain areas. This guidance is effective for fiscal years beginning after December 15, 2023, including interim periods therein. Early adoption is permitted. The Company adopted this ASU on January 1, 2023. There is no impact to the Company's consolidated financial statements. |
