Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Organization and Summary of Significant Accounting Policies | Note 1. Organization and Summary of Significant Accounting Policies Organization Metacrine, Inc. (the “Company”) was incorporated in the state of Delaware on September 17, 2014 and is based in San Diego, California. The Company is a clinical-stage biopharmaceutical company focused on building an innovative pipeline of differentiated drugs to treat liver and gastrointestinal diseases. Principles of Consolidation In May 2019, the Company established a wholly-owned Australian subsidiary, Metacrine, Pty Ltd, in order to conduct various clinical activities for its product candidates. The consolidated financial statements include the accounts of the Company and Metacrine, Pty Ltd. The functional currency of both the Company and Metacrine, Pty Ltd is the U.S. dollar. Assets and liabilities that are not denominated in the functional currency are remeasured into U.S. dollars at foreign currency exchange rates in effect at the balance sheet date except for nonmonetary assets, which are remeasured at historical foreign currency exchange rates in effect at the date of transaction. Net realized and unrealized gains and losses from foreign currency transactions and remeasurement are reported in other income (expense) in the consolidated statements of operations and comprehensive loss. All intercompany accounts and transactions have been eliminated in consolidation. Initial Public Offering On September 18, 2020, the Company closed its initial public offering (“IPO”) of 6,540,000 shares of common stock at a public offering price of $13.00 per share. The Company raised $76.9 million in net proceeds from the IPO after deducting underwriters’ discounts and commissions of $6.0 million and issuance costs of $2.2 million. Upon closing of the Company’s IPO, all of the Company’s outstanding preferred stock were automatically converted into 16,685,014 shares of common stock. Liquidity and Capital Resources From its inception through December 31, 2020, the Company has devoted substantially all its efforts to organizing and staffing, business planning, raising capital, researching, discovering and developing its pipeline in FXR and other drug targets, and general and administrative support for these operations and has funded its operations primarily with the net proceeds from the issuance of convertible preferred stock, common stock, and long-term debt. The Company has incurred net losses and negative cash flows from operations since inception and had an accumulated deficit of $120.7 million and $83.4 million as of December 31, 2020 and 2019, respectively. Management expects the Company will incur substantial operating losses for the foreseeable future in order to complete clinical trials and launch and commercialize any product candidates for which it receives regulatory approval. The Company will need to raise additional capital through a combination of equity offerings, debt financings, collaborations, and other similar arrangements. The Company’s ability to raise additional capital may be adversely impacted by potential worsening of economic conditions in the United States and worldwide resulting from the COVID-19 pandemic. If the disruption persists and deepens, the Company could experience an inability to access additional capital. As of December 31, 2020, the Company had available cash, cash equivalents, and short-term investments of $96.2 million and working capital of $98.0 million to fund future operations. Management has prepared cash flow forecasts which indicate that, based on the Company’s current cash resources available and working capital, the Company will have sufficient resources to fund its operations for at least one year after the date the financial statements are issued. Use of Estimates The Company’s consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of the Company’s consolidated financial statements requires it to make estimates and assumptions that impact the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities. The most significant estimates in the Company’s consolidated financial statements relate to accruals for research and development expenses and stock-based compensation. These estimates and assumptions are based on current facts, historical experience, and various other factors 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 and the recording of expenses that are not readily apparent from other sources. Actual results may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include cash in readily available checking accounts, money market funds, and commercial paper. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents are valued at cost, which approximates fair value. Short-Term Investments Short-term investments primarily consist of commercial paper, corporate debt securities, asset backed securities, and U.S. government and agency bonds. The Company has classified these investments as available-for-sale securities, as the sale of such investments may be required prior to maturity to implement management strategies, and therefore has classified all short-term investments with maturity dates beyond three months at the date of purchase as current assets in the accompanying consolidated balance sheets. Short-term investments are carried at fair value with the unrealized gains and losses included in other comprehensive loss as a component of stockholders’ equity until realized. Any premium or discount arising at purchase is amortized and/or accreted to interest income as an adjustment to yield using the straight-line method over the life of the instrument. A decline in the market value of any short-term investment below amortized cost that is determined to be other-than-temporary will result in a revaluation of its carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. No such impairment charges have been recorded for any period presented. Realized gains and losses are determined using the specific identification method and are included in other income (expense). Fair Value Measurement The Company accounts for certain assets and liabilities at their fair value. The Company uses the following fair value hierarchy to indicate the extent to which the inputs used to determine fair value are observable in the market: • Level 1 : Inputs are based on quoted prices for identical assets in active markets. • Level 2 : Inputs, other than Level 1, that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 : Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, and short-term investments. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. Property and Equipment, Net Property and equipment are stated at cost and depreciated on a straight-line basis over the estimated useful life of the related assets (generally three to five years). Leasehold improvements are stated at cost and amortized on a straight-line basis over the lesser of the remaining lease term or the estimated useful life of the leasehold improvements. Repairs and maintenance costs are charged to expense as incurred. Leases At the inception of a contractual arrangement, the Company determines whether the contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. Lease terms are determined at the commencement date by considering whether renewal options and termination options are reasonably assured of exercise. For its long-term operating leases, the Company recognizes a lease liability and a right-of-use (“ROU”) asset on its consolidated balance sheets and recognizes lease expense on a straight-line basis over the lease term. The lease liability is determined as the present value of future lease payments using the discount rate implicit in the lease or, if the implicit rate is not readily determinable, an estimate of the Company’s incremental borrowing rate. The ROU asset is based on the lease liability, adjusted for any prepaid or deferred rent. The Company aggregates all lease and non-lease components for each class of underlying assets into a single lease component and variable charges for common area maintenance and other variable costs are recognized as expense as incurred. The Company has elected to not recognize a lease liability or ROU asset in connection with short-term operating leases and recognizes lease expense for short-term operating leases on a straight-line basis over the lease term. The Company does not have any financing leases. Impairment of Long-Lived Assets The Company reviews long-lived assets, such as property and equipment, for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Fair value would be assessed using discounted cash flows or other appropriate measures of fair value. The Company did not recognize any impairment losses during the years ended December 31, 2020 and 2019. Warrant Liability The Company issued a freestanding warrant to purchase shares of its Series C convertible preferred stock. Since the underlying Series C convertible preferred stock was classified as temporary equity, the Series C convertible preferred stock warrant was classified as a liability as of December 31, 2019 in the accompanying consolidated balance sheets. The Company adjusted the carrying value of such Series C convertible preferred stock warrant to its estimated fair value at each reporting date, with any related increases or decreases in the fair value recorded within other income (expense) in the consolidated statements of operations and comprehensive loss. The Series C convertible preferred stock warrant was automatically converted into a warrant to purchase 23,122 shares of common stock upon completion of the Company’s IPO in September 2020. The Company adjusted the carrying value of the Series C convertible preferred stock warrant to reflect its estimated fair value on the IPO date and ceased recognizing any fair value adjustments subsequent to its conversion to a common stock warrant. Research and Development Costs All costs of research and development are expensed in the period incurred. Research and development costs primarily consist of salaries and related expenses for personnel, stock-based compensation, external research and development costs incurred under agreements with contract research organizations, investigative sites and consultants to conduct our preclinical, toxicology and clinical studies, milestone payments resulting from license agreements, laboratory supplies, costs related to compliance with regulatory requirements, costs related to manufacturing the Company’s product candidates for clinical trials and preclinical studies, facilities, depreciation, and other allocated expenses. Payments made prior to the receipt of goods or services to be used in research and development are capitalized until the related goods are delivered or services performed. The Company has entered into various research and development contracts with clinical research organizations, clinical manufacturing organizations, and other companies. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and payments made in advance of performance are reflected in the accompanying consolidated balance sheets as prepaid expenses and other current assets. The Company records accruals for estimated costs incurred for ongoing research and development activities. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the services, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates may be made in determining the prepaid or accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. Patent Costs Costs related to filing and pursuing patent applications are recorded as general and administrative expenses and expensed as incurred since recoverability of such expenditures is uncertain. Stock-Based Compensation Stock-based compensation expense represents the cost of the grant date fair value of stock option grants recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model and recognizes forfeitures as they occur. Income Taxes Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions on the basis of a two-step process whereby (1) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. Any accrued interest and penalties are included within the related tax liability. Comprehensive Loss Comprehensive loss is defined as a change in equity during a period from transactions and other events and circumstances from non-owner sources. The only component of other comprehensive loss is unrealized gains (losses) on available-for-sale securities. Comprehensive gains (losses) have been reflected in the consolidated statements of operations and comprehensive loss and as a separate component in the consolidated statements of convertible preferred stock and stockholders’ equity (deficit) for all periods presented. Segment Reporting Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. The Company and its chief operating decision-maker view the Company’s operations and manages its business in one operating segment. Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments — Credit Losses, to improve financial reporting by requiring timely recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This guidance will become effective for the Company beginning January 1, 2023, with early adoption permitted. The Company early adopted ASU No. 2016-13 during the first quarter of 2021. The standard did not have a material impact on the Company’s consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU No. 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740 and also improves consistent application by clarifying and amending existing guidance. The Company adopted ASU No. 2019-12 during the first quarter of 2021. The standard did not have a material impact on the Company’s consolidated financial statements. Net Loss Per Share Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding for the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common shares and dilutive common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. Dilutive common stock equivalents are comprised of convertible preferred stock, preferred and common stock warrants, unvested common stock subject to repurchase, and options outstanding under the Company’s stock option plan. Potentially dilutive securities not included in the calculation of diluted net loss per share because to do so would be anti-dilutive are as follows (in common stock equivalent shares): December 31, 2020 2019 Convertible preferred stock — 16,685,014 Common stock options 3,136,076 1,684,630 Unvested common stock 36,492 197,549 Preferred stock warrant — 23,122 Common stock warrant 23,122 — Total 3,195,690 18,590,315 |

Commitments and Contingencies | Note 3 . Commitments and Contingencies Operating Leases The Company entered into a five-year noncancelable operating lease in June 2017 for its corporate headquarters in San Diego, California under an agreement that commenced in March 2018. Under the terms of the agreement, there is no option to extend the lease and the Company is subject to additional charges for common area maintenance and other costs. Monthly rental payments due under the lease commenced in March 2018 and escalate throughout the lease term. Information related to the Company’s operating lease is as follows (in thousands): Years Ended December 31, 2020 2019 Operating lease expense (including variable costs of $317 and $300 during the years ended December 31, 2020 and 2019, respectively) $ 1,103 $ 1,090 Cash paid for amounts included in the measurement of lease liabilities $ 767 $ 715 As of December 31, 2020 and 2019, the remaining lease term of the Company’s operating lease was 27 months and 39 months, respectively, and the discount rate on the Company’s operating lease was 8.0% during each of the respective years.

The Company is required to use commercially reasonable efforts to achieve certain diligence milestones with respect to the FXR Licensed Products, including with respect to developing, producing and selling FXR Licensed Products. The Company is also required to pay The Salk up to $6.5 million in milestone payments upon the completion of certain clinical and regulatory milestones, certain of which payments the Company may defer under certain circumstances. The Company is also obligated to pay The Salk a low single-digit percentage royalty on net sales, with a minimum annual royalty payment due beginning with the first commercial sale of each FXR Licensed Product. The applicable minimum annual royalty payment amount depends on the number of years that have elapsed since the first commercial sale of an FXR Licensed Product and is in the hundreds-of-thousands-of-dollars range. In addition, if the Company chooses to sublicense the FXR Licensed Product to any third parties, the Company must pay to The Salk a low single-digit percentage of all sublicensing revenue. In addition, in the event of a change of control, the Company is required to pay The Salk a low single-digit percentage of any payments and consideration that it receives in consideration of the change of control. The Company has accrued $0.3 million in milestone payments based upon the achievement of certain regulatory milestones as of December 31, 2020. Contingencies In the event the Company becomes subject to claims or suits arising in the ordinary course of business, the Company would accrue a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. |

Long-Term Debt | Note 4 . Long-Term Debt Long-term debt consists of the following (in thousands): December 31, 2020 2019 Long-term debt $ 10,000 $ 10,000 Unamortized debt discount (628 ) (901 ) Long-term debt, net of debt discount $ 9,372 $ 9,099 On August 27, 2019, the Company entered into a Loan and Security Agreement (the “Loan Agreement”, and all amounts borrowed thereunder the “Term Loan”) with a lender (the “Lender”). The Company borrowed $10.0 million (“the Term Loan”) at the inception of the Loan Agreement. The remaining borrowings available under the Loan and Security Agreement have expired. The Term Loan bears interest at a floating annual rate equal to the greater of (i) the prime rate used by the Lender plus 2.0% (5.25% and 6.75% at December 31, 2020 and 2019, respectively), and (ii) 7.25%. The monthly payments are interest-only until September 1, 2022. Subsequent to the interest-only period, the Term Loan will be payable in equal monthly installments of principal plus accrued and unpaid interest, through the maturity date of September 1, 2023 (“Maturity Date”). In addition, the Company is obligated to pay a final payment fee of 5.25% of the original principal amount of the Term Loan on the Maturity Date. As of December 31, 2020 and 2019, the final payment fee of $0.5 million has been recorded as a long-term liability. The Company may elect to prepay all, but not less than all, of the Term Loan prior to the Maturity Date, subject to a prepayment fee of up to 3.0% of the then outstanding principal balance. After repayment, no Term Loan amounts may be borrowed again. The Company’s obligations under the Loan Agreement are secured by a security interest in substantially all of its assets, other than its intellectual property. The Loan Agreement includes customary affirmative and negative covenants and also includes standard events of default, including an event of default based on the occurrence of a material adverse event, and a default under any agreement with a third party resulting in a right of such third party to accelerate the maturity of any debt in excess of $0.3 million. The negative covenants include, among others, restrictions on the Company transferring collateral, incurring additional indebtedness, engaging in mergers or acquisitions, paying cash dividends or making other distributions, making investments, creating liens, selling assets and making any payment on subordinated debt, in each case subject to certain exceptions. Upon the occurrence and continuance of an event of default, the Lender may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Loan Agreement. As of December 31, 2020 and 2019, the Company was in compliance with all applicable covenants under the Loan Agreement. In connection with the Loan Agreement, the Company issued the Lender a warrant (the “Lender Warrant”) to purchase shares of the Company’s Series C convertible preferred stock at an exercise price of $10.812 per share and expiring on August 27, 2029. The number of Series C convertible preferred shares issuable upon exercise of the warrant is an amount equal to (i) 2.5% of the aggregate Term Loan funded under the Loan Agreement divided by (ii) $10.812. Upon the funding of the Term Loan, the Lender Warrant was initially exercisable for 117,924 shares of Series C convertible preferred stock. The Lender Warrant was automatically converted into a warrant to purchase 23,122 shares of common stock upon completion of the Company’s IPO in September 2020. The initial $0.2 million fair value of the Lender Warrant, $0.5 million final payment fee, and $0.3 million of debt issuance costs were recorded as a debt discount and are being amortized to interest expense using the effective interest method over the term of the Term Loan. For the years ended December 31, 2020 and 2019, the Company recognized $1.0 million and $0.3 million of interest expense, including $0.3 million and $0.1 million of debt discount amortization, respectively, in connection with the Loan Agreement. As of December 31, 2020 and 2019, the Company had an outstanding Term Loan of $10.0 million and accrued interest of $0.1 million, respectively. Future minimum principal and interest payments under the Term Loan, including the final payment fee, as of December 31, 2020 are as follows (in thousands): December 31, 2020 2021 $ 735 2022 4,438 2023 6,949 Total principal and interest payments 12,122 Less interest and final payment fee (2,122 ) Long-term debt $ 10,000 |

Equity [Abstract] | |
Convertible Preferred Stock and Stockholders' Equity | Note 7 Equity Incentive Plan In January 2015, the Company adopted the Metacrine, Inc. 2015 Equity Incentive Plan (as amended, the “2015 Plan”), which provides for the grant of incentive stock options, nonstatutory stock options, restricted stock awards, restricted stock unit awards, and stock appreciation rights to its employees, members of its board of directors, and consultants. In August 2020, the Company’s Board of Directors approved the 2020 Equity Incentive Plan (the “2020 Plan”), which is the successor and continuation of the 2015 Plan. No additional awards may be granted under the 2015 Plan and all outstanding awards under the 2015 Plan remain subject to the terms of the 2015 Plan. As of December 31, 2020, there were 2,907,742 shares authorized and available for issuance under the 2020 Plan. Recipients of incentive stock options are eligible to purchase shares of the Company’s common stock at an exercise price equal to no less than the estimated fair market value of such stock on the date of grant. The maximum term of options granted under the 2015 and 2020 Plans (or collectively, the “Equity Plans”) is ten years and, in general, the options issued under the Equity Plans vest over a four-year period from the vesting commencement date. The 2015 Plan allows for early exercise of stock options, which may be subject to repurchase by the Company at the lower of (i) the fair market value at the repurchase date or (ii) the original exercise price. The early exercise of stock options is not permitted under the 2020 Plan. A summary of the Company’s unvested shares and unvested stock liability is as follows (in thousands, except share data): Number of Unvested Shares Unvested Stock Liability Balance at December 31, 2019 197,549 109 Repurchased shares (4,269 ) (2 ) Vested shares (156,788 ) (80 ) Balance at December 31, 2020 36,492 $ 27 A summary of the Company’s stock option activity is as follows (in thousands, except share and per share data): Number of Outstanding Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term (In Years) Aggregate Intrinsic Value Balance at December 31, 2019 1,684,630 $ 2.47 8.73 $ 911 Granted 1,872,266 $ 7.23 Exercised (102,792 ) $ 1.56 Cancelled (318,028 ) $ 3.56 Balance at December 31, 2020 3,136,076 $ 5.23 7.95 $ 8,963 Vested and expected to vest at December 31, 2020 3,136,076 $ 5.23 7.95 $ 8,963 Exercisable at December 31, 2020 1,018,775 $ 2.58 5.35 $ 5,384 The weighted average grant date fair value per share of option grants for the years ended December 31, 2020 and 2019 (excluding the impact of the modifications described below) was $8.33 and $2.09, respectively. The total intrinsic value of stock options exercised during the years ended December 31, 2020 and 2019 was $0.9 million and $49 thousand, respectively. The assumptions used in the Black-Scholes option pricing model to determine the fair value of stock option grants were as follows: Years Ended December 31, 2020 2019 Risk-free interest rate 0.4% – 0.7% 1.8% –1.9% Expected volatility 82.4% – 94.8% 72.6% – 81.0% Expected term (in years) 5.8 – 10.0 5.1 – 6.1 Expected dividend yield 0.0% 0.0% Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for zero coupon U.S. Treasury notes with maturities similar to the expected term of the awards. Expected volatility. Since the Company recently completed its IPO and does not have sufficient trading history for its common stock, the expected volatility assumption is based on volatilities of a peer group of similar companies in the biotechnology industry whose share prices are publicly available. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its own stock price becomes available. Expected term. The expected term represents the period of time that options are expected to be outstanding. Because the Company does not have sufficient historical exercise behavior, it determines the expected life assumption using the simplified method, for employees, which is an average of the contractual term of the option and its vesting period. The expected term for nonemployee options is equal to the contractual term. Expected dividend yield. The Company bases the expected dividend yield assumption on the fact that it has never paid cash dividends and has no present intention to pay cash dividends and, therefore, used an expected dividend yield of zero. Employee Stock Purchase Plan In September 2020, the Company’s Board of Directors and stockholders adopted and approved the 2020 Employee Stock Purchase Plan (the “ESPP”). The ESPP permits eligible employees, who elect to participate in an offering under the ESPP, to contribute up to 15% of their eligible gross compensation towards the purchase of shares of common stock. Eligible employees can purchase up to 20,000 shares of common stock on a given purchase date. The price at which stock is purchased under the ESPP is equal to 85% of the fair market value of the Company’s common stock on the commencement date of each offering period or the relevant purchase date, whichever is lower. Offerings under the ESPP are approximately two years in duration and consist of four purchase periods that are approximately six months in duration. The ESPP is considered a compensatory plan as defined by the authoritative guidance for stock-based compensation. Stock-based compensation expense attributable to the ESPP was immaterial during the year ended December 31, 2020. As of December 31, 2020, there were 405,000 shares of common stock available for future issuance under the ESPP. Stock-Based Compensation Expense Stock-based compensation expense recognized for all equity awards has been reported in the consolidated statements of operations and comprehensive loss as follows (in thousands): Years Ended December 31, 2020 2019 Research and development $ 1,233 $ 836 General and administrative 3,788 1,096 Total stock-based compensation $ 5,021 $ 1,932 As of December 31, 2020, unrecognized stock-based compensation cost was $14.4 million, which is expected to be recognized over a remaining weighted average period of approximately 3.0 years. Stock Option Modification In June 2020, the Company entered into a separation and consulting agreement in connection with the resignation of Dr. Song as the Company’s President and Chief Executive Officer. Under the terms of the separation and consulting agreement, Dr. Song received $0.1 million in cash compensation, was provided the potential of an extended period of time to exercise vested stock options if certain conditions are met, and continued to vest while he provided consulting services to the Company through December 31, 2020. The benefits received in connection with the potential extended exercise period and continued vesting as originally scheduled were considered modifications to the original terms of the equity that Dr. Song maintains. These modifications resulted in incremental fair value of $1.1 million, which was recognized in full on a straight-line basis through December 31, 2020. Common Stock Reserved for Future Issuance Common stock reserved for future issuance consists of the following: Years Ended December 31, 2020 2019 Conversion of preferred stock — 16,685,014 Common stock options outstanding 3,136,076 1,684,630 Shares available for issuance under equity incentive plans 2,907,742 616,423 Shares available for issuance under the ESPP 405,000 — Common stock warrant 23,122 — Preferred stock warrant — 23,122 Total common stock reserved for future issuance 6,471,940 19,009,189 |

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law in the U.S. in March 2020. The CARES Act adjusted a number of provisions of the tax code, including the eligibility of certain deductions and the treatment of net operating losses and tax credits. The CARES Act repeals the 80% limitation for taxable years beginning before January 1, 2021. The enactment of the CARES Act did not result in any material adjustments to the Company’s income tax provision for the year ended December 31, 2020 or to its deferred tax assets as of December 31, 2020. California Assembly Bill 85 (“AB 85”) was signed into law by Governor Gavin Newsom on June 29, 2020. It was passed by both houses of the California state legislature on June 15, 2020. AB 85 disallows California net operating losses for any taxable year beginning on or after January 1, 2020, and before January 1, 2023 for any corporation with a net business or modified adjusted gross income of more than $1 million for the taxable year. This bill also limits any business credit to offset a maximum of $5 million of California tax, including the California Research Credit. The Company does not expect any material impacts related to this tax law change. As of December 31, 2020, the Company had federal net operating loss carryforwards of $108.1 million, of which $81.4 million were generated in tax years beginning after 2017 and can be carried forward indefinitely. Net operating losses generated after December 31, 2017 are also subject to an 80% limitation if utilized after 2020. The remaining federal net operating loss carryforwards of $26.7 million, which were generated prior to December 31, 2017, will begin to expire in 2034, if not previously utilized. As of December 31, 2020, the Company had state loss carryforwards of $71.4 million, which will begin to expire in 2034, if not previously utilized. As of December 31, 2020, the Company also had foreign loss carryforwards of $0.6 million, which do not expire. As of December 31, 2020, the Company had federal and state research and development tax credit carryforwards of $3.2 million and $1.9 million, respectively. The federal research and development tax credit carryforwards expire beginning in 2035, unless previously utilized. The state research and development tax credit carryforwards may be carried forward indefinitely. The Company has not completed a Section 382 study to assess whether an ownership change has occurred or whether there have been multiple ownership changes since the Company’s formation due to the complexity and cost associated with such a study and the fact that there may be additional such ownership changes in the future. Pursuant to Internal Revenue Code Sections 382 and 383, annual use of the Company’s net operating loss and research and development tax credit carryforwards may be limited in the event a cumulative change in ownership of more than 50% occurs within a three-year period. If eliminated, the related asset would be removed from the deferred tax asset schedule with a corresponding reduction in the valuation allowance. Due to the existence of the valuation allowance, limitations created by future ownership changes, if any, will not impact the Company’s effective tax rate. The following table summarizes the changes to the Company’s unrecognized tax benefits (in thousands): Balance at December 31, 2018 $ 479 Increases related to prior year positions 183 Balance at December 31, 2019 662 Increases related to current year positions 212 Balance at December 31, 2020 $ 874 As of December 31, 2020 and 2019, the Company had unrecognized tax benefits of $0.9 million and $0.7 million, respectively. The Company has not recognized interest or penalties related to unrecognized tax benefits. The Company does not expect that there will be a significant change in the unrecognized tax benefits over the next twelve months. Due to the existence of the valuation allowance, future changes in the Company’s unrecognized tax benefits will not impact the effective tax rate. The Company is subject to taxation in the United States, California, and Australia. The Company is subject to income tax examination by tax authorities in those jurisdictions for the years beginning in 2014 due to the carryforward of unutilized net operating losses and research and development credits. The Company is not currently under examination by any jurisdiction. |

The Company raised $76.9 million in net proceeds from the IPO after deducting underwriters’ discounts and commissions of $6.0 million and issuance costs of $2.2 million. Upon closing of the Company’s IPO, all of the Company’s outstanding preferred stock were automatically converted into 16,685,014 shares of common stock. |
Liquidity and Capital Resources | Liquidity and Capital Resources From its inception through December 31, 2020, the Company has devoted substantially all its efforts to organizing and staffing, business planning, raising capital, researching, discovering and developing its pipeline in FXR and other drug targets, and general and administrative support for these operations and has funded its operations primarily with the net proceeds from the issuance of convertible preferred stock, common stock, and long-term debt. The Company has incurred net losses and negative cash flows from operations since inception and had an accumulated deficit of $120.7 million and $83.4 million as of December 31, 2020 and 2019, respectively. Management expects the Company will incur substantial operating losses for the foreseeable future in order to complete clinical trials and launch and commercialize any product candidates for which it receives regulatory approval. The Company will need to raise additional capital through a combination of equity offerings, debt financings, collaborations, and other similar arrangements. The Company’s ability to raise additional capital may be adversely impacted by potential worsening of economic conditions in the United States and worldwide resulting from the COVID-19 pandemic. If the disruption persists and deepens, the Company could experience an inability to access additional capital. As of December 31, 2020, the Company had available cash, cash equivalents, and short-term investments of $96.2 million and working capital of $98.0 million to fund future operations. Management has prepared cash flow forecasts which indicate that, based on the Company’s current cash resources available and working capital, the Company will have sufficient resources to fund its operations for at least one year after the date the financial statements are issued. |
Use of Estimates | Use of Estimates The Company’s consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of the Company’s consolidated financial statements requires it to make estimates and assumptions that impact the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities. The most significant estimates in the Company’s consolidated financial statements relate to accruals for research and development expenses and stock-based compensation. These estimates and assumptions are based on current facts, historical experience, and various other factors 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 and the recording of expenses that are not readily apparent from other sources. Actual results may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected. |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include cash in readily available checking accounts, money market funds, and commercial paper. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents are valued at cost, which approximates fair value. |
Short-Term Investments | Short-Term Investments Short-term investments primarily consist of commercial paper, corporate debt securities, asset backed securities, and U.S. government and agency bonds. The Company has classified these investments as available-for-sale securities, as the sale of such investments may be required prior to maturity to implement management strategies, and therefore has classified all short-term investments with maturity dates beyond three months at the date of purchase as current assets in the accompanying consolidated balance sheets. Short-term investments are carried at fair value with the unrealized gains and losses included in other comprehensive loss as a component of stockholders’ equity until realized. Any premium or discount arising at purchase is amortized and/or accreted to interest income as an adjustment to yield using the straight-line method over the life of the instrument. A decline in the market value of any short-term investment below amortized cost that is determined to be other-than-temporary will result in a revaluation of its carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. No such impairment charges have been recorded for any period presented. Realized gains and losses are determined using the specific identification method and are included in other income (expense). |
Fair Value Measurement | Fair Value Measurement The Company accounts for certain assets and liabilities at their fair value. The Company uses the following fair value hierarchy to indicate the extent to which the inputs used to determine fair value are observable in the market: • Level 1 : Inputs are based on quoted prices for identical assets in active markets. • Level 2 : Inputs, other than Level 1, that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 : Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. |
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, and short-term investments. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. |
Property and Equipment, Net | Property and Equipment, Net Property and equipment are stated at cost and depreciated on a straight-line basis over the estimated useful life of the related assets (generally three to five years). Leasehold improvements are stated at cost and amortized on a straight-line basis over the lesser of the remaining lease term or the estimated useful life of the leasehold improvements. Repairs and maintenance costs are charged to expense as incurred. |
Leases | Leases At the inception of a contractual arrangement, the Company determines whether the contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. Lease terms are determined at the commencement date by considering whether renewal options and termination options are reasonably assured of exercise. For its long-term operating leases, the Company recognizes a lease liability and a right-of-use (“ROU”) asset on its consolidated balance sheets and recognizes lease expense on a straight-line basis over the lease term. The lease liability is determined as the present value of future lease payments using the discount rate implicit in the lease or, if the implicit rate is not readily determinable, an estimate of the Company’s incremental borrowing rate. The ROU asset is based on the lease liability, adjusted for any prepaid or deferred rent. The Company aggregates all lease and non-lease components for each class of underlying assets into a single lease component and variable charges for common area maintenance and other variable costs are recognized as expense as incurred. The Company has elected to not recognize a lease liability or ROU asset in connection with short-term operating leases and recognizes lease expense for short-term operating leases on a straight-line basis over the lease term. The Company does not have any financing leases. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company reviews long-lived assets, such as property and equipment, for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Fair value would be assessed using discounted cash flows or other appropriate measures of fair value. The Company did not recognize any impairment losses during the years ended December 31, 2020 and 2019. |
Warrant Liability | Warrant Liability The Company issued a freestanding warrant to purchase shares of its Series C convertible preferred stock. Since the underlying Series C convertible preferred stock was classified as temporary equity, the Series C convertible preferred stock warrant was classified as a liability as of December 31, 2019 in the accompanying consolidated balance sheets. The Company adjusted the carrying value of such Series C convertible preferred stock warrant to its estimated fair value at each reporting date, with any related increases or decreases in the fair value recorded within other income (expense) in the consolidated statements of operations and comprehensive loss. The Series C convertible preferred stock warrant was automatically converted into a warrant to purchase 23,122 shares of common stock upon completion of the Company’s IPO in September 2020. The Company adjusted the carrying value of the Series C convertible preferred stock warrant to reflect its estimated fair value on the IPO date and ceased recognizing any fair value adjustments subsequent to its conversion to a common stock warrant. |
Research and Development Costs | Research and Development Costs All costs of research and development are expensed in the period incurred. Research and development costs primarily consist of salaries and related expenses for personnel, stock-based compensation, external research and development costs incurred under agreements with contract research organizations, investigative sites and consultants to conduct our preclinical, toxicology and clinical studies, milestone payments resulting from license agreements, laboratory supplies, costs related to compliance with regulatory requirements, costs related to manufacturing the Company’s product candidates for clinical trials and preclinical studies, facilities, depreciation, and other allocated expenses. Payments made prior to the receipt of goods or services to be used in research and development are capitalized until the related goods are delivered or services performed. The Company has entered into various research and development contracts with clinical research organizations, clinical manufacturing organizations, and other companies. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and payments made in advance of performance are reflected in the accompanying consolidated balance sheets as prepaid expenses and other current assets. The Company records accruals for estimated costs incurred for ongoing research and development activities. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the services, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates may be made in determining the prepaid or accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. |
Patent Costs | Patent Costs Costs related to filing and pursuing patent applications are recorded as general and administrative expenses and expensed as incurred since recoverability of such expenditures is uncertain. |
Stock-Based Compensation | Stock-Based Compensation Stock-based compensation expense represents the cost of the grant date fair value of stock option grants recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model and recognizes forfeitures as they occur. |
Income Taxes | Income Taxes Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions on the basis of a two-step process whereby (1) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. Any accrued interest and penalties are included within the related tax liability. |
Comprehensive Loss | Comprehensive Loss Comprehensive loss is defined as a change in equity during a period from transactions and other events and circumstances from non-owner sources. The only component of other comprehensive loss is unrealized gains (losses) on available-for-sale securities. Comprehensive gains (losses) have been reflected in the consolidated statements of operations and comprehensive loss and as a separate component in the consolidated statements of convertible preferred stock and stockholders’ equity (deficit) for all periods presented. |
Segment Reporting | Segment Reporting Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. The Company and its chief operating decision-maker view the Company’s operations and manages its business in one operating segment. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments — Credit Losses, to improve financial reporting by requiring timely recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This guidance will become effective for the Company beginning January 1, 2023, with early adoption permitted. The Company early adopted ASU No. 2016-13 during the first quarter of 2021. The standard did not have a material impact on the Company’s consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU No. 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740 and also improves consistent application by clarifying and amending existing guidance. The Company adopted ASU No. 2019-12 during the first quarter of 2021. The standard did not have a material impact on the Company’s consolidated financial statements. |
Net Loss Per Share | Net Loss Per Share Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding for the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common shares and dilutive common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. Dilutive common stock equivalents are comprised of convertible preferred stock, preferred and common stock warrants, unvested common stock subject to repurchase, and options outstanding under the Company’s stock option plan. Potentially dilutive securities not included in the calculation of diluted net loss per share because to do so would be anti-dilutive are as follows (in common stock equivalent shares): December 31, 2020 2019 Convertible preferred stock — 16,685,014 Common stock options 3,136,076 1,684,630 Unvested common stock 36,492 197,549 Preferred stock warrant — 23,122 Common stock warrant 23,122 — Total 3,195,690 18,590,315 |
