Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Business and Principal Activities | 1. Business and Principal Activities Description of Business Applied Molecular Transport Inc. (the Company) is a clinical-stage biopharmaceutical company leveraging its proprietary technology platform to design and develop a pipeline of novel oral biologic product candidates to treat autoimmune, inflammatory, metabolic, and other diseases. The Company is building a portfolio of oral product candidates based on its technology platform including its most advanced product candidate, AMT-101, a gastrointestinal (GI)-selective oral fusion of interleukin-10 (IL-10) and the Company’s proprietary carrier molecule. The Company is actively enrolling and dosing patients globally across multiple Phase 2 clinical trials of AMT-101 in ulcerative colitis (UC) and other inflammatory indications following the completion of a Phase 1b clinical trial in patients with UC. The Company’s second product candidate, AMT-126, is a GI-selective oral fusion of interleukin-22 (IL-22) and the Company’s proprietary carrier molecule, which is currently in development for diseases related to intestinal epithelial (IE) barrier function defects driven by activation of the innate immune system. The Company is currently enrolling subjects in a Phase 1 clinical trial with AMT-126. The Company’s proprietary technology platform enables it to design and develop various oral biologic therapeutic modalities, such as peptides, proteins, full-length antibodies, antibody fragments, and ribonucleic acid (RNA) therapeutics, with the potential for significant advantages over existing marketed and development-stage drugs. Since the date of incorporation in Delaware on November 21, 2016, the Company has devoted substantially all of its resources to research and development activities, including research activities such as drug discovery, preclinical studies, and clinical trials as well as development activities such as the manufacturing of clinical and research material, establishing and maintaining an intellectual property portfolio, hiring personnel, raising capital, and providing general and administrative support for these operations. Initial Public Offering On June 4, 2020, the Company’s registration statement on Form S-1 (File No. 333-238464) relating to its initial public offering (IPO) of common stock became effective. The IPO closed on June 9, 2020 at which time the Company issued an aggregate of 12,650,000 shares of its common stock at a price of $14.00 per share which included 1,650,000 shares of common stock issued in connection with the full exercise by the underwriters of their option to purchase additional shares of common stock. In addition, immediately prior to the closing of the IPO, all outstanding shares of the Company’s convertible preferred stock automatically converted into 13,966,292 shares of common stock. The aggregate offering price for shares sold in the IPO was $177.1 million. After deducting underwriting discounts and commissions of $12.4 million and offering costs paid or payable by the Company of $4.1 million ( including offering costs of $0.2 million paid in 2019) Follow-On Offering On April 6, 2021, the Company completed a follow-on offering and issued 2,875,000 shares of its common stock, including 375,000 shares of common stock issued in connection with the full exercise by the underwriters of their options to purchase additional shares of common stock at a price of $42.00 per share. The aggregate gross proceeds from the follow-on offering were $120.8 million. After deducting underwriting discounts and commissions of $7.2 million and deferred offering costs of $0.8 million, the net proceeds from the follow-on offering were approximately $112.8 million. Liquidity and Capital Resources Management believes that its existing cash, cash equivalents, and investments as of September 30, 2021 will be sufficient to allow the Company to fund its current operating plan through at least 12 months after the date of issuance of these condensed financial statements. The Company has incurred significant losses and negative cash flows from operations since its inception. Risks and Uncertainties The extent to which the COVID-19 pandemic impacts the Company’s business will depend on future developments which are highly uncertain and cannot be predicted, such as the duration of the outbreak, th |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Condensed Financial Statements (Unaudited) The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and applicable rules and regulations of the U.S. Securities and Exchange Commission (SEC) for interim reporting. As permitted under those rules and regulations, certain footnotes or other financial information normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. The interim condensed financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal, recurring adjustments that are necessary to present fairly the Company’s results for the interim periods presented. The condensed balance sheet as of December 31, 2020, was derived from the Company’s audited financial statements. The results of operations during the three and nine months ended September 30, 2021, are not necessarily indicative of the results to be expected for the year ending December 31, 2021, or for any other future annual or interim period. The accompanying interim unaudited condensed financial statements should be read in conjunction with the audited financial statements and the related notes thereto for the year ended December 31, 2020, which are included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 19, 2021. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company bases its estimates on historical experience and market-specific or other relevant assumptions that it believes are reasonable under the circumstances. Assets and liabilities reported in the Company’s condensed balance sheet and expenses and income reported are affected by estimates and assumptions, which are used for, but are not limited to, estimating research and development expenses and determining the fair value of assets and liabilities, including common stock valuation, income tax uncertainties, and measurement of stock-based compensation expense. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of the COVID-19 pandemic. Actual results could differ from such estimates or assumptions. Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, and investments. The Company invests in U.S. Treasury securities. The Company maintains bank deposits in federally insured financial institutions and these deposits may exceed federally insured limits. The Company is exposed to credit risk in the event of default by the financial institutions holding its cash, cash equivalents, and investments to the extent recorded in the condensed balance sheet. The Company has not experienced any losses on its deposits of cash, cash equivalents, and investments. The Company is subject to a number of risks similar to other early-stage biopharmaceutical companies, including, but not limited to, the need to obtain adequate additional funding, possible failure of current or future preclinical studies or clinical trials, its reliance on third parties to conduct its clinical trials, the need to obtain regulatory and marketing approvals for its product candidates, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of the Company’s product candidates, protection of its proprietary technology, and the need to secure and maintain adequate manufacturing arrangements with third parties or develop internal manufacturing capabilities. The Company’s product candidates will require approval from the U.S. Food and Drug Administration (FDA) and/or comparable foreign regulatory agencies prior to commercialization in their respective jurisdictions. If the Company does not successfully commercialize or partner any of its product candidates, it will be unable to generate product revenue or achieve profitability. Operating Segment The Company operates and manages its business as one reportable and operating segment, which is the business of designing and developing a pipeline of novel oral biologic product candidates to treat autoimmune, inflammatory, metabolic, and other diseases. The Company’s chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for allocating and evaluating financial performance. Cash and Cash Equivalents Cash and cash equivalents are held in accounts at financial institutions. Such deposits have and will continue to exceed federally insured limits in the foreseeable future. The Company considers all highly liquid investments purchased with original maturities of 90 days or less from the purchase date to be cash equivalents. Cash equivalents consist of amounts invested in money market funds exclusively composed of U.S. government obligations. Restricted Cash As of September 30, 2021, restricted cash is comprised of two collateral accounts related to letters of credit issued on behalf of the Company for the security deposits on the leased and subleased properties in South San Francisco. The collateralized cash in connection with the letters of credit is classified as restricted cash on the condensed balance sheet based on the terms of the agreements. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the condensed statements of cash flows (in thousands): September 30, September 30, 2021 2020 Cash and cash equivalents $ 152,455 $ 11,314 Restricted cash 1,025 108 Total cash, cash equivalents and restricted cash $ 153,480 $ 11,422 Investments The Company’s investments have been classified and accounted for as available-for-sale securities. Fixed income securities consist of U.S. Treasury securities. The specific identification method is used to determine the cost basis of fixed income securities sold. These securities are recorded on the condensed balance sheets at fair value. Unrealized gains and losses on these securities are included as a separate component of accumulated other comprehensive income or loss. The cost of investment securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in other expense, net. The Company classifies its investments as short or long term primarily based on the remaining contractual maturity of the securities. Property and Equipment, Net Property and equipment are presented at cost, net of accumulated depreciation. Depreciation is recorded using the straight-line method. Depreciation begins at the time the asset is placed in service. Maintenance and repairs are charged to expense as incurred and costs of major replacement or improvement are capitalized. The Company’s estimated useful lives of its property and equipment are as follows: Laboratory and manufacturing equipment 5 years Computer and office equipment 3 years Leasehold improvements Shorter of remaining lease term or estimated useful life Impairment of Long-Lived Assets The Company evaluates the carrying amount of its long-lived assets whenever events or changes in circumstances indicate that the assets may not be recoverable. An impairment loss is recognized when the remaining book value of an asset is not recoverable. There was no impairment on long-lived assets during the nine months ended September 30, 2021 and 2020, respectively. Leases In February 2016, the Financial Accounting Standards Board (FASB) issued a Accounting Standard Update (ASU) No. 2016-02, Leases (ASC 842), and its associated amendments, that establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months and disclose key information about leasing arrangements. The Company adopted ASC 842 on January 1, 2021 using the modified retrospective approach. Leases have been classified as either finance or operating, with classification affecting the pattern and classification of expense recognition in the condensed statements of operations and comprehensive loss. At the inception of an arrangement, the Company determine s if an arrangement is, or contains, a lease based on the facts and circumstances present in that arrangement. Lease classification, recognition, and measurement are then determined at the lease commencement date. For arrangements that contain a lease , the Company ( i ) identif ies lease and non-lease components, (ii) determine s the consideration in the contract, (iii) determine s whether the lease is an operating or financ e lease; and (iv) recognize s lease ROU assets and liabilities. Lease liabilities and their corresponding ROU assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable . Accordingly , the Company use s the incremental borrowing rate based on the information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment. Most leases include options to renew and/or terminate the lease, which can impact the lease term. The exercise of these options is at the Company’s discretion. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. The Company has operating leases for its corporate offices, laboratory, manufacturing and warehouse facilities, and a contract research organization (CRO) embedded lease arrangement. Fixed lease payments on operating leases are recognized as lease expense over the expected term of the lease on a straight-line basis. Variable lease expenses that are not considered fixed are recognized as incurred. Fixed and variable lease expense on operating leases is recognized within operating expenses within the Company’s condensed statements of operations and comprehensive loss. The Company has finance leases for lab and manufacturing equipment. Interest expense from fixed payments on finance leases is recognized using the effective interest method. Finance lease ROU asset amortization and interest expense are recorded within operating expenses and interest income, net, respectively, within the Company’s condensed statements of operations and comprehensive loss. The Company has elected the short-term lease exemption and, therefore, does not recognize an ROU asset or corresponding liability for lease arrangements with an original term of 12 months or less. Research and Development Expenses Research and development expenses are expensed as incurred. Research and development expenses include personnel costs related to research and development activities, materials costs, external clinical product candidate manufacturing and clinical trial costs, outside services costs, repair, maintenance and depreciation costs for research and development equipment, as well as facility costs for laboratory space used for research and development activities. Accrued Research and Development Expenses The Company records accruals for estimated costs of research, preclinical studies, clinical trials, manufacturing and development, within accrued expenses which are significant components of research and development expenses. A substantial portion of the Company’s ongoing research and development activities is conducted by third-party service providers, CROs and contract development and manufacturing organizations (CDMOs). The Company’s contracts with the CROs and CDMOs generally include fees such as clinical trial fees, initiation fees, reservation fees, costs related to animal studies and safety tests, verification run costs, materials and reagents expenses, taxes, etc. The financial terms of these contracts are subject to negotiation, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided to the Company under such contracts. The Company accrues the costs incurred under agreements with these third parties based on estimates of actual work completed in accordance with the respective agreements. The Company determines the estimated costs through discussions with internal personnel and external service providers as to the progress, stage of completion or actual timeline (start-date and end-date) of the services and the agreed-upon fees to be paid for such services. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company adjusts its accrued expenses or prepaid expenses accordingly, which impact research and development expenses. Although the Company does not expect its estimates to be materially different from amounts actually incurred, the Company’s understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may impact the amount of expense recognized. To date, there have not been any material adjustments to the Company’s prior estimates of research and development expenses. Stock-Based Compensation Expense The Company maintains both an equity incentive plan and an employee stock purchase plan (ESPP) as long-term incentives for its employees, consultants and directors. The equity incentive plan allows for the issuance of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock grants and restricted stock units. The ESPP has an offering period of two years comprised of four purchase periods. The ESPP allows employees to purchase shares of the Company’s common stock each purchase period based on a percentage of their compensation subject to certain limits. As of September 30, 2021, no stock appreciation rights, restricted stock grants, restricted stock units or performance-based awards were issued. The Company accounts for stock-based compensation expense by measuring and recognizing compensation expense for all share-based payments made to employees and non-employees based on estimated grant-date fair values. The grant-date fair values for options are recorded as stock-based compensation expense on a straight-line basis over each recipient’s requisite service period, which is generally the vesting period. The grant-date fair values for the ESPP are recorded as stock-based compensation expense on a straight-line basis over the applicable purchase period. Actual forfeitures are recognized as a reduction of stock-based compensation expense in the period incurred. The Company estimates the fair value of stock options granted to employees and non-employees using the Black-Scholes model. The Company estimates the fair value of ESPP for each purchase period at the beginning of the offering period using the Black-Scholes model. The Black-Scholes model requires the input of assumptions, including expected volatility, expected dividend yield, expected term and the risk-free rate of return. Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability, or an exit price, in the principal or most advantageous market for that asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurement establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. The Company determined the fair value of financial assets and liabilities using the fair value hierarchy that describes three levels of inputs that may be used to measure fair value, as follows: ▪ Level 1—Quoted prices in active markets for identical assets and liabilities; ▪ 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; and ▪ 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. As of September 30, 2021 and December 31, 2020, fair value measurements consisted mainly of cash equivalents and investments. The carrying amounts of these instruments approximated their fair value. Comprehensive Loss Comprehensive loss includes net loss and other comprehensive (loss) income for the period. Other comprehensive (loss) income represents unrealized (loss) or gain on investments. Emerging Growth Company Status The Company is an emerging growth company (EGC) as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act) and may take advantage of reduced reporting requirements that are otherwise applicable to public companies. Section 107 of the JOBS Act exempts EGCs from being required to comply with new or revised financial accounting standards until private companies are required to comply with those standards. The Company has elected to use the extended transition period for complying with new or revised accounting standards. Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are recorded if and when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective may not have a material impact on the Company’s financial position or results of operations upon adoption. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842) The Company adopted the new standard on January 1, 2021 using the modified retrospective approach. The Company has elected to apply the transition method that allows companies to continue applying the guidance under the lease standard in effect at that time in the comparative periods presented in the condensed financial statements and recognize a cumulative-effect adjustment to the opening balance of accumulated deficit on the date of adoption. The Company has elected to combine lease components (for example fixed rent payments) with non-lease components (for example, common-area maintenance costs) on the facilities, lab equipment and CRO embedded lease asset classes. The Company also elected the “package of practical expedients”, which permits the Company not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. Lastly, the Company elected a practical expedient to use hindsight in determining the lease term for all its leases. Results for reporting periods beginning after January 1, 2021 are presented under the new standard, while prior period amounts have not been adjusted and continue to be reported under the accounting standards in effect for the prior period. Upon adoption of the new lease standard on January 1, 2021, the Company capitalized operating lease ROU assets of $6.0 million, with opening adjustments of $0.5 million related to deferred rent existing as of the transition date, and $6.5 million of operating lease liabilities, within the Company’s condensed balance sheets. There was no impact to the finance lease ROU asset and the finance lease liabilities upon adoption. In connection with operating and finance leases, there was no impact to the accumulated deficit upon the adoption of the new standard on January 1, 2021. In October 2020, the FASB issued ASU 2020-10, Codification Improvements |

Fair Value Measurements | 3. Fair Value Measurements As of September 30, 2021, the Company held $30.1 million of investment securities, comprised of U.S. Treasury securities. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. Financial instruments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, or historical pricing trends of a security relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. In addition, the Company assesses the inputs and methods used to determine the fair value and classify securities according to the fair value hierarchy. The carrying amounts of cash equivalents and investment s approximate their fair value based upon quoted market prices. Certain of the Company’s financial instruments are recorded at amounts that approximate their fair value, rather than at fair value on a recurring basis, due to their liquid or short-term nature, such as cash, accounts payable and accrued expenses . There were no unrealized losses on short-term investments as of September 30, 2021. The Company did not recognize an allowance for credit losses as of September 30, 2021.

The intrinsic value of options exercised during the three and nine months ended September 30, 2021 was $4.1 million and $18.9 million, respectively. As of September 30, 2021, the Company had $60.4 million of unrecognized stock-based compensation expense, related to options granted but not yet amortized, which will be recognized over a weighted-average period of approximately 2.77 years. 2020 Employee Stock Purchase Plan Under the Company’s 2020 Employee Stock Purchase Plan (the 2020 ESPP), employees can purchase shares of the Company’s common stock each purchase period based on a percentage of their compensation, subject to certain limits. The purchase price per share is equal to the lower of 85% of the fair market value of the Company’s common stock on the enrollment date or the purchase date. The 2020 ESPP offers a six-month look-back feature as well as an automatic rollover feature that provides for the offering period to be reset to a new lower-priced offering price if the market price of the stock at the purchase date is lower than the stock price at the initial enrollment date. In that case, the offering period is immediately cancelled after that purchase date, and a new two-year offering period is established using the then-current stock price as the base purchase price. The shares authorized for the 2020 ESPP increase annually by the lesser of (i) 628,012 shares, (ii) 1% of the Company’s common stock shares outstanding on the last day of its immediately preceding fiscal year, or (iii) such other amount as determined by the Company’s Board of Directors. Accordingly, effective January 1, 2021, the number of shares in the 2020 ESPP increased by 351,214 shares, representing 1% of the prior year end’s common stock outstanding. As of September 30, 2021, 654,671 shares of common stock remained available for future issuance under the 2020 ESPP. The Company began recording stock-based compensation expense for its ESPP on January 1, 2021. During the three and nine months ended September 30, 2021, the Company recorded $0.1 million and $0.2 million, respectively, of stock-based compensation expense related to the ESPP.

Accounting Policies [Abstract] | |
Condensed Financial Statements (Unaudited) | Condensed Financial Statements (Unaudited) The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and applicable rules and regulations of the U.S. Securities and Exchange Commission (SEC) for interim reporting. As permitted under those rules and regulations, certain footnotes or other financial information normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. The interim condensed financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal, recurring adjustments that are necessary to present fairly the Company’s results for the interim periods presented. The condensed balance sheet as of December 31, 2020, was derived from the Company’s audited financial statements. The results of operations during the three and nine months ended September 30, 2021, are not necessarily indicative of the results to be expected for the year ending December 31, 2021, or for any other future annual or interim period. The accompanying interim unaudited condensed financial statements should be read in conjunction with the audited financial statements and the related notes thereto for the year ended December 31, 2020, which are included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 19, 2021. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company bases its estimates on historical experience and market-specific or other relevant assumptions that it believes are reasonable under the circumstances. Assets and liabilities reported in the Company’s condensed balance sheet and expenses and income reported are affected by estimates and assumptions, which are used for, but are not limited to, estimating research and development expenses and determining the fair value of assets and liabilities, including common stock valuation, income tax uncertainties, and measurement of stock-based compensation expense. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of the COVID-19 pandemic. Actual results could differ from such estimates or assumptions. |
Concentration of Credit Risk and Other Risks and Uncertainties | Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, and investments. The Company invests in U.S. Treasury securities. The Company maintains bank deposits in federally insured financial institutions and these deposits may exceed federally insured limits. The Company is exposed to credit risk in the event of default by the financial institutions holding its cash, cash equivalents, and investments to the extent recorded in the condensed balance sheet. The Company has not experienced any losses on its deposits of cash, cash equivalents, and investments. The Company is subject to a number of risks similar to other early-stage biopharmaceutical companies, including, but not limited to, the need to obtain adequate additional funding, possible failure of current or future preclinical studies or clinical trials, its reliance on third parties to conduct its clinical trials, the need to obtain regulatory and marketing approvals for its product candidates, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of the Company’s product candidates, protection of its proprietary technology, and the need to secure and maintain adequate manufacturing arrangements with third parties or develop internal manufacturing capabilities. The Company’s product candidates will require approval from the U.S. Food and Drug Administration (FDA) and/or comparable foreign regulatory agencies prior to commercialization in their respective jurisdictions. If the Company does not successfully commercialize or partner any of its product candidates, it will be unable to generate product revenue or achieve profitability. |
Operating Segment | Operating Segment The Company operates and manages its business as one reportable and operating segment, which is the business of designing and developing a pipeline of novel oral biologic product candidates to treat autoimmune, inflammatory, metabolic, and other diseases. The Company’s chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for allocating and evaluating financial performance. |
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents are held in accounts at financial institutions. Such deposits have and will continue to exceed federally insured limits in the foreseeable future. The Company considers all highly liquid investments purchased with original maturities of 90 days or less from the purchase date to be cash equivalents. Cash equivalents consist of amounts invested in money market funds exclusively composed of U.S. government obligations. |
Restricted Cash | Restricted Cash As of September 30, 2021, restricted cash is comprised of two collateral accounts related to letters of credit issued on behalf of the Company for the security deposits on the leased and subleased properties in South San Francisco. The collateralized cash in connection with the letters of credit is classified as restricted cash on the condensed balance sheet based on the terms of the agreements. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the condensed statements of cash flows (in thousands): September 30, September 30, 2021 2020 Cash and cash equivalents $ 152,455 $ 11,314 Restricted cash 1,025 108 Total cash, cash equivalents and restricted cash $ 153,480 $ 11,422 |
Investments | Investments The Company’s investments have been classified and accounted for as available-for-sale securities. Fixed income securities consist of U.S. Treasury securities. The specific identification method is used to determine the cost basis of fixed income securities sold. These securities are recorded on the condensed balance sheets at fair value. Unrealized gains and losses on these securities are included as a separate component of accumulated other comprehensive income or loss. The cost of investment securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in other expense, net. The Company classifies its investments as short or long term primarily based on the remaining contractual maturity of the securities. |
Property and Equipment, Net | Property and Equipment, Net Property and equipment are presented at cost, net of accumulated depreciation. Depreciation is recorded using the straight-line method. Depreciation begins at the time the asset is placed in service. Maintenance and repairs are charged to expense as incurred and costs of major replacement or improvement are capitalized. The Company’s estimated useful lives of its property and equipment are as follows: Laboratory and manufacturing equipment 5 years Computer and office equipment 3 years Leasehold improvements Shorter of remaining lease term or estimated useful life |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company evaluates the carrying amount of its long-lived assets whenever events or changes in circumstances indicate that the assets may not be recoverable. An impairment loss is recognized when the remaining book value of an asset is not recoverable. There was no impairment on long-lived assets during the nine months ended September 30, 2021 and 2020, respectively. |
Leases | Leases In February 2016, the Financial Accounting Standards Board (FASB) issued a Accounting Standard Update (ASU) No. 2016-02, Leases (ASC 842), and its associated amendments, that establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months and disclose key information about leasing arrangements. The Company adopted ASC 842 on January 1, 2021 using the modified retrospective approach. Leases have been classified as either finance or operating, with classification affecting the pattern and classification of expense recognition in the condensed statements of operations and comprehensive loss. At the inception of an arrangement, the Company determine s if an arrangement is, or contains, a lease based on the facts and circumstances present in that arrangement. Lease classification, recognition, and measurement are then determined at the lease commencement date. For arrangements that contain a lease , the Company ( i ) identif ies lease and non-lease components, (ii) determine s the consideration in the contract, (iii) determine s whether the lease is an operating or financ e lease; and (iv) recognize s lease ROU assets and liabilities. Lease liabilities and their corresponding ROU assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable . Accordingly , the Company use s the incremental borrowing rate based on the information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment. Most leases include options to renew and/or terminate the lease, which can impact the lease term. The exercise of these options is at the Company’s discretion. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. The Company has operating leases for its corporate offices, laboratory, manufacturing and warehouse facilities, and a contract research organization (CRO) embedded lease arrangement. Fixed lease payments on operating leases are recognized as lease expense over the expected term of the lease on a straight-line basis. Variable lease expenses that are not considered fixed are recognized as incurred. Fixed and variable lease expense on operating leases is recognized within operating expenses within the Company’s condensed statements of operations and comprehensive loss. The Company has finance leases for lab and manufacturing equipment. Interest expense from fixed payments on finance leases is recognized using the effective interest method. Finance lease ROU asset amortization and interest expense are recorded within operating expenses and interest income, net, respectively, within the Company’s condensed statements of operations and comprehensive loss. The Company has elected the short-term lease exemption and, therefore, does not recognize an ROU asset or corresponding liability for lease arrangements with an original term of 12 months or less. |
Research and Development Expenses | Research and Development Expenses Research and development expenses are expensed as incurred. Research and development expenses include personnel costs related to research and development activities, materials costs, external clinical product candidate manufacturing and clinical trial costs, outside services costs, repair, maintenance and depreciation costs for research and development equipment, as well as facility costs for laboratory space used for research and development activities. |
Accrued Research and Development Expenses | Accrued Research and Development Expenses The Company records accruals for estimated costs of research, preclinical studies, clinical trials, manufacturing and development, within accrued expenses which are significant components of research and development expenses. A substantial portion of the Company’s ongoing research and development activities is conducted by third-party service providers, CROs and contract development and manufacturing organizations (CDMOs). The Company’s contracts with the CROs and CDMOs generally include fees such as clinical trial fees, initiation fees, reservation fees, costs related to animal studies and safety tests, verification run costs, materials and reagents expenses, taxes, etc. The financial terms of these contracts are subject to negotiation, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided to the Company under such contracts. The Company accrues the costs incurred under agreements with these third parties based on estimates of actual work completed in accordance with the respective agreements. The Company determines the estimated costs through discussions with internal personnel and external service providers as to the progress, stage of completion or actual timeline (start-date and end-date) of the services and the agreed-upon fees to be paid for such services. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company adjusts its accrued expenses or prepaid expenses accordingly, which impact research and development expenses. Although the Company does not expect its estimates to be materially different from amounts actually incurred, the Company’s understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may impact the amount of expense recognized. To date, there have not been any material adjustments to the Company’s prior estimates of research and development expenses. |
Stock-Based Compensation Expense | Stock-Based Compensation Expense The Company maintains both an equity incentive plan and an employee stock purchase plan (ESPP) as long-term incentives for its employees, consultants and directors. The equity incentive plan allows for the issuance of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock grants and restricted stock units. The ESPP has an offering period of two years comprised of four purchase periods. The ESPP allows employees to purchase shares of the Company’s common stock each purchase period based on a percentage of their compensation subject to certain limits. As of September 30, 2021, no stock appreciation rights, restricted stock grants, restricted stock units or performance-based awards were issued. The Company accounts for stock-based compensation expense by measuring and recognizing compensation expense for all share-based payments made to employees and non-employees based on estimated grant-date fair values. The grant-date fair values for options are recorded as stock-based compensation expense on a straight-line basis over each recipient’s requisite service period, which is generally the vesting period. The grant-date fair values for the ESPP are recorded as stock-based compensation expense on a straight-line basis over the applicable purchase period. Actual forfeitures are recognized as a reduction of stock-based compensation expense in the period incurred. The Company estimates the fair value of stock options granted to employees and non-employees using the Black-Scholes model. The Company estimates the fair value of ESPP for each purchase period at the beginning of the offering period using the Black-Scholes model. The Black-Scholes model requires the input of assumptions, including expected volatility, expected dividend yield, expected term and the risk-free rate of return. |
Fair Value Measurements | Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability, or an exit price, in the principal or most advantageous market for that asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurement establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. The Company determined the fair value of financial assets and liabilities using the fair value hierarchy that describes three levels of inputs that may be used to measure fair value, as follows: ▪ Level 1—Quoted prices in active markets for identical assets and liabilities; ▪ 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; and ▪ 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. As of September 30, 2021 and December 31, 2020, fair value measurements consisted mainly of cash equivalents and investments. The carrying amounts of these instruments approximated their fair value. |
Comprehensive Loss | Comprehensive Loss Comprehensive loss includes net loss and other comprehensive (loss) income for the period. Other comprehensive (loss) income represents unrealized (loss) or gain on investments. |
Emerging Growth Company Status | Emerging Growth Company Status The Company is an emerging growth company (EGC) as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act) and may take advantage of reduced reporting requirements that are otherwise applicable to public companies. Section 107 of the JOBS Act exempts EGCs from being required to comply with new or revised financial accounting standards until private companies are required to comply with those standards. The Company has elected to use the extended transition period for complying with new or revised accounting standards. |
Commitments and Contingencies | Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are recorded if and when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. |
Recent Accounting Pronouncements and Recently Adopted Accounting Pronouncements | Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective may not have a material impact on the Company’s financial position or results of operations upon adoption. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842) The Company adopted the new standard on January 1, 2021 using the modified retrospective approach. The Company has elected to apply the transition method that allows companies to continue applying the guidance under the lease standard in effect at that time in the comparative periods presented in the condensed financial statements and recognize a cumulative-effect adjustment to the opening balance of accumulated deficit on the date of adoption. The Company has elected to combine lease components (for example fixed rent payments) with non-lease components (for example, common-area maintenance costs) on the facilities, lab equipment and CRO embedded lease asset classes. The Company also elected the “package of practical expedients”, which permits the Company not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. Lastly, the Company elected a practical expedient to use hindsight in determining the lease term for all its leases. Results for reporting periods beginning after January 1, 2021 are presented under the new standard, while prior period amounts have not been adjusted and continue to be reported under the accounting standards in effect for the prior period. Upon adoption of the new lease standard on January 1, 2021, the Company capitalized operating lease ROU assets of $6.0 million, with opening adjustments of $0.5 million related to deferred rent existing as of the transition date, and $6.5 million of operating lease liabilities, within the Company’s condensed balance sheets. There was no impact to the finance lease ROU asset and the finance lease liabilities upon adoption. In connection with operating and finance leases, there was no impact to the accumulated deficit upon the adoption of the new standard on January 1, 2021. In October 2020, the FASB issued ASU 2020-10, Codification Improvements |

Equity incentive plan term | Under the Company’s 2020 Employee Stock Purchase Plan (the 2020 ESPP), employees can purchase shares of the Company’s common stock each purchase period based on a percentage of their compensation, subject to certain limits. The purchase price per share is equal to the lower of 85% of the fair market value of the Company’s common stock on the enrollment date or the purchase date. The 2020 ESPP offers a six-month look-back feature as well as an automatic rollover feature that provides for the offering period to be reset to a new lower-priced offering price if the market price of the stock at the purchase date is lower than the stock price at the initial enrollment date. In that case, the offering period is immediately cancelled after that purchase date, and a new two-year offering period is established using the then-current stock price as the base purchase price. | ||||
