Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization, Going Concern and Basis of Presentation | 1. Organ ization, Going Concern and Basis of Presentation Lyra Therapeutics, Inc. (the “Company”) is a clinical-stage biotechnology company focused on the development and commercialization of therapies for the localized treatment of patients with chronic rhinosinusitis, or CRS. The Company’s proprietary technology is designed to consistently deliver medicines directly to the affected tissue for sustained periods with a single administration. The Company’s product candidates, LYR-210 and LYR-220, are bioabsorbable nasal implants designed to be administered in a simple, in-office procedure and intended to deliver six months of continuous anti-inflammatory drug therapy to the sinonasal passages for the treatment of CRS. The Company was incorporated as a Delaware corporation on November 21, 2005 and is located in Watertown, Massachusetts. On July 16, 2018, the Company formerly changed its name from 480 Biomedical, Inc. to Lyra Therapeutics, Inc. The Company is subject to risks common to companies in the therapeutics and pharmaceutical industry, including but not limited to, risks of failure of preclinical studies and clinical trials, the need to obtain marketing approval for any drug product candidate that it may identify and develop, the need to successfully commercialize and gain market acceptance of its product candidates, dependence on key personnel, protection of proprietary technology, compliance with government regulations, development by competitors of technological innovations, reliance on third party manufacturers, ability to transition from pilot-scale manufacturing to large-scale production of products and the need to obtain adequate additional financing to fund the development of its product candidates. Going Concern From inception through March 31, 2024, the Company has raised an aggregate of $ 424.8 million to fund its operations, of which $ 162.1 million were gross proceeds from sales of redeemable convertible preferred stock, $ 96.3 million were net proceeds from the April 2022 Financing (as defined below), $ 46.5 million were net proceeds from the May 2023 Financing (as defined below), $ 57.3 million were net proceeds from the Company’s initial public offering, $ 23.9 million of ATM proceeds related to the Company’s Controlled Equity Offering Agreement (the “Original Sales Agreement”) dated September 1, 2023, $ 16.8 million were gross proceeds from government contracts, $ 17.0 million were gross proceeds from the LianBio License Agreement, and $ 3.8 million from the exercise of common stock warrants. Further, the Company currently has an effective shelf registration statement on Form S-3 (No. 333-278163) filed with the SEC on March 22, 2024 (“Form S-3”), under which it may offer from time to time in one or more offerings any combination of common and preferred stock, debt securities, warrants and units of up to $ 300.0 million in the aggregate. The Company has incurred recurring net operating losses every year since inception and has an accumulated deficit of approximately $ 333.8 million at March 31, 2024. The Company expects to continue to generate operating losses for the foreseeable future. At March 31, 2024, the Company had approximately $ 15.8 million of cash and cash equivalents and $ 71.3 million of short-term investments. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these condensed consolidated financial statements are issued. The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) assuming the Company will continue as a going concern and contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company expects to incur increased costs as it progresses its product candidates through clinical development. The Company will need additional financing to support its continuing operations and pursue its growth strategy. Until such time as the Company can generate significant revenue from product sales, if ever, it plans to finance its operations through a combination of equity or debt financings, collaboration agreements, strategic alliances and licensing arrangements. The Company may be unable to raise additional funds or enter into such other agreements when needed on favorable terms or at all. The inability to obtain funding as and when needed would have a negative impact on the Company’s financial condition and ability to pursue its business strategies. If the Company is unable to obtain funding when needed, the Company could be forced to delay, reduce or eliminate some or all of its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations. The Company will need to generate significant revenue to achieve profitability, and it may never do so. Basis of Presentation The accompanying interim condensed consolidated financial statements and related disclosures are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the Securities and Exchange Commission on March 22, 2024. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standard Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). In management’s opinion, these unaudited condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s condensed consolidated financial statements for the periods presented. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies The Company’s significant accounting policies are disclosed in the audited consolidated financial statements for the year ended December 31, 2023, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 22, 2024. Since the date of those financial statements, there have been no changes to its significant accounting policies except as noted below. Comprehensive Loss Comprehensive loss includes net loss as well as other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. For the three months ended March 31, 2024 and 2023, other comprehensive income (loss) consisted of unr ealized gains and losses, net of taxes from its short-term investments. Restricted Cash The Company had restricted cash of approximately $ 2.0 million as of March 31, 2024 and approximately $ 1.4 million as of December 31, 2023. These balances were held as of March 31, 2024 at one of the Company’s financial institutions to secure the Company’s letters of credit for its facility leases. The Company’s statements of cash flows include restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on such statements. A reconciliation of the cash, cash equivalents, and restricted cash reported within the balance sheet that sum to the total of the same amounts shown in the statement of cash flows is as follows: March 31, December 31, 2024 2023 Cash and cash equivalents $ 15,799 $ 22,353 Restricted cash 1,992 1,392 Total $ 17,791 $ 23,745 Net Loss per Share The Company has reported losses since inception and has computed basic net loss per share attributable to common stockholders by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities. The Company has included pre-funded warrants in its computation of basic net loss per share based on the nominal exercise price. The Company applies the two-class method to calculate its basic and diluted net loss per share, as the Company has issued shares that meet the definition of participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. The Company’s participating securities contractually entitle the holders of such shares to participate in dividends, but do not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, such losses are not allocated to such participating securities. Additionally, in periods in which the Company reports a net loss, diluted net loss per share is the same as basic net loss per share, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The following table sets forth the potentially dilutive securities that have been excluded from the calculation of diluted net loss per share because to include them would be anti-dilutive (in common stock equivalent shares): Three Months Ended 2024 2023 Stock options 8,053,774 5,495,826 Common stock warrants 8,606,303 — Restricted stock units 1,061,029 260,616 Total 17,721,106 5,756,442 Recently Issued 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 Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. Effective January 1, 2024, the Company, as required, adopted ASU No. 2023-07, Segment Reporting (Topic 280) (“ASU 2023-07”) Improvements to Reportable Segment Disclosure for its annual financial statements and notes thereto for the year ending December 31, 2024 to be included in its 2024 Annual Report on Form 10-K. The Company is not required to adopt the standard for interim periods until the first quarter of 2025. This standard requires disclosure of significant segment expenses that are regularly provided to the CODM and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items to reconcile to segment profit or loss and the title and position of the entity's CODM. The Company will include the required disclosure information in the notes to the financial statements for the year ending December 31, 2024 included in its 2024 Annual Report on Form 10-K and is required apply ASU No. 2023-07 on a retrospective basis. The adoption of ASU No. 2023-07 will include expanded disclosure for its 2024 financial statements, but the Company does not expect that there will be a material impact to the financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to provide enhancements to annual income tax disclosures. In particular, the standard will require more detailed information in the income tax rate reconciliation, as well as the disclosure of income taxes paid disaggregated by jurisdiction, among other enhancements. The standard is effective for years beginning after December 15, 2024 and early adoption is permitted. The Company is currently evaluating the impact of the standard on the presentation of its consolidated financial statements and footnotes. Effective January 1, 2023, the Company adopted Accounting Standards Update (ASU) No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). ASU 2016-13 requires that credit losses be reported as an allowance using an expected losses model, representing the entity’s current estimate of credit losses expected to be incurred. For available-for-sale debt securities with unrealized losses, this standard now requires allowances to be recorded instead of reducing the amortized cost of the investment. The adoption of ASU 2016-13 did not have a material impact on its consolidated financial statements. |

As of March 31, 2024, the Company's short-term investments consisted of U.S. treasury bills which were valued based on Level 2 inputs. As of December 31, 2023, the Company’s cash equivalents were invested in money market funds and U.S. treasury bills, which were valued based on Level 1 and Level 2 inputs, respectively. As of December 31, 2023, the Company's short-term investments consisted of U.S. treasury bills which were valued based on Level 2 inputs and U.S. Government Agency Securities and foreign national bank securities, which were valued based on Level 2 inputs. In determining the fair value of its investments at each date presented above, the Company relied on quoted prices for similar securities in active markets or using other inputs that are observable or can be corroborated by observable market data for Level 2 investments. All available-for-sale securities have contractual maturities of less than one year. The Company did no t have any financial assets or liabilities during any of the periods presented in the accompanying consolidated financial statements that required Level 3 inputs. The carrying values of the Company’s accounts payable, accrued expenses and deferred revenue approximate their fair values due to the short-term nature of these liabilities and as such these are considered Level 1 in the fair value hierarchy. |

Equity [Abstract] | |
Preferred and Common Stock | 4. Preferred and Common Stock The Company has 10,000,000 shares of undesignated preferred stock, par value $ 0.001 per share. There were no shares issued or outstanding as of March 31, 2024 or 2023. The holders of common stock are entitled to one vote for each share held. Common stockholders are not entitled to receive dividends, unless declared by the Board of Directors (the “Board of Directors”). The Company currently has an effective shelf registration statement on Form S-3 (No. 333-278163) filed with the SEC on March 22, 2024 (“Form S-3”), under which it may offer from time to time in one or more offerings any combination of common and preferred stock, debt securities, warrants and units of up to $ 300.0 million in the aggregate. September 2023 Financing On September 1, 2023, the Company entered into a Controlled Equity Offering Sales Agreement (the "Original Sales Agreement") with Cantor Fitzgerald & Co. ("Cantor") pursuant to which the Company may offer and sell, from time to time through Cantor, shares of the Company's common stock for aggregate gross proceeds of up to $ 50.0 million. The offering and sale of up to $ 50.0 million of the common shares has been registered under the Securities Act of 1933, as amended (the "Securities Act"), pursuant to the Company's Registration Statement on Form S-3 (File No. 333-256020) (the "Registration Statement"), which was originally filed with the SEC on May 11, 2021, and declared effective by the SEC on May 20, 2021, the base prospectus contained within the Registration Statement, and a prospectus supplement relating to the shares that was filed with the SEC on September 1, 2023. Pursuant to the Original Sales Agreement, Cantor may sell the shares in sales deemed to be "at the market offerings" as defined in Rule 415(a)(4) promulgated under the Securities Act. The Company has no obligation to sell any of the shares under the Original Sales Agreement and may at any time suspend or terminate the offering of the shares pursuant to the Original Sales Agreement upon notice to Cantor and subject to other conditions. Cantor will act as sales agent and will use commercially reasonable efforts to sell on the Company's behalf all of the shares requested to be sold by the Company, on mutually agreed terms between Cantor and the Company. The Original Sales Agreement contains customary representations, warranties and agreements by the Company, and indemnification obligations of the Company and Cantor and other obligations of the parties. Under the terms of the Original Sales Agreement, the Company has agreed to pay Cantor a commission equal to 3.0 % of the aggregate gross proceeds from any shares sold through it pursuant to the Original Sales Agreement. In addition, the Company has agreed to reimburse certain expenses incurred by Cantor in connection with the Original Sales Agreement. On February 14, 2024, the Company issued 1,041,666 shares under the Company’s ATM agreement with net proceeds of $ 4.8 million. On March 22, 2024, the Company amended and restated the Controlled Equity Offering Sales Agreement with Cantor Fitzgerald & Co. ("Cantor") pursuant to which the Company may offer and sell, from time to time through Cantor, shares of the Company's common stock for aggregate gross proceeds of up to $ 75.0 million. The offering and sale of up to $ 75.0 million of the common shares has been registered under the Securities Act of 1 933, as amended (the "Securities Act"), pursuant to the Company's Registration Statement on Form S-3 (File No. 333-278163) (the "Registration Statement"), which was originally filed with the Securities and Exchange Commission on March 22, 2024, the base prospectus contained within the Registration Statement, and a prospectus supplement relating to the shares that was filed with the SEC on March 22, 2024 (the "Prospectus Supplement"). May 2023 Financing On May 25, 2023, the Company entered into the Purchase Agreement, with the purchasers, pursuant to which the Company agreed to sell securities to the Investors in a private placement (the “Private Placement”). The Purchase Agreement provided for the sale and issuance by the Company of: 17,652,962 shares of the Company’s common stock and accompanying warrants to purchase up to 8,826,481 shares of the Company’s common stock (Purchase Warrants), with an exercise price of $ 2.67 per share, for aggregate gross proceeds of $ 44.0 million. Each Purchase Warrant became exercisable on November 30, 2023, and expires on November 30, 2028. Additionally, the Company issued Pre-Funded Warrants to purchase 2,408,188 shares of the Company’s common stock (Pre-Funded Warrants), with an exercise price of $ 0.001 per share, and accompanying purchase warrants to purchase up to 1,204,094 shares of the Company’s common stock (Purchase Warrants), with an exercise price of $ 2.673 per share, for aggregate gross proceeds of $ 6.0 million. In total 10,030,575 Purchase Warrants were issued and 2,408,188 Pre-Funded Warrants were issued. The Pre-Funded Warrants are immediately exercisable and expire on May 31, 2028. The closing of the Private Placement occurred on May 31, 2023. The Company received an aggregate of $ 50.0 million in gross proceeds, or $ 46.5 million after deducting issuance costs. The Company has allocated the net proceeds among the common stock, the Purchase Warrants and the Pre-Funded Warrants using the relative fair value method for each of the above transactions. The Company has allocated $ 30.5 million to the shares of common stock, $ 4.2 million to the Pre-Funded Warrants and $ 12.0 million to the Purchase Warrants. The Company’s outstanding warrants are freestanding instruments and are classified within stockholders’ equity since the warrants are indexed to the Company’s common stock and meet the equity classification criteria. A total of 1,424,272 Purchase Warrants were exercised related to the May 2023 financing as of March 31, 2024 at a purchase price of $ 2.673 per share. April 2022 Financing On April 13, 2022, the Company announced the closing of its private placement of common stock (or, in lieu thereof, Pre-Funded Warrants to purchase common stock), resulting in gross proceeds of approximately $ 100.5 million (the “April 2022 Financing”). The Company received approximately $ 96.3 million in net proceeds after deducting estimated offering costs of $ 4.2 million. Pursuant to the securities purchase agreement, (i) certain investors purchased an aggregate of 18,815,159 shares of common stock at $ 4.22 per share for gross proceeds to the Company of $ 79.4 million and (ii) certain investors purchased Pre-Funded Warrants to purchase an aggregate of 5,000,000 shares of common stock, with the exercise price of $ 0.001 per share for gross proceeds of $ 21.1 million to the Company. The warrants are exercisable on or after April 13, 2022 and expire on April 12, 2027. The Pre-Funded Warrants were classified as a component of stockholders’ equity within additional paid-in capital and were recorded at the issuance date using a relative fair value allocation method. The Pre-Funded Warrants are equity classified because they are freestanding financial instruments that are legally detachable and separately exercisable from the equity instruments, are immediately exercisable, do not embody an obligation for the Company to repurchase its shares, permit the holders to receive a fixed number of shares of common stock upon exercise, are indexed to the Company’s common stock and meet the equity classification criteria. In addition, such Pre-Funded Warrants do not provide any guarantee of value or return. The Company valued the Pre-Funded Warrants at issuance, concluding that their sales price approximated their fair value, and allocated net proceeds from the sale proportionately to the common stock and Pre-Funded Warrants, of which $ 19.7 million was allocated to the Pre-Funded Warrants and recorded as a component of additional paid-in capital. There were 2,906,923 Pre-Funded Warrants issued in the April 2022 Financing exercised as of March 31, 2024. The Company has reserved for future issuances the following shares of common stock as of March 31, 2024: As of March 31, 2024 Pre-funded warrants 4,500,849 Common stock warrants 8,606,303 Stock options and restricted stock units 10,077,077 Employee stock purchase plan 724,906 Total 23,909,135 |

Stock-based compensation expense included in the Company’s consolidated statements of operations and comprehensive loss was as follows (in thousands): Three Months Ended 2024 2023 Research and development $ 703 $ 284 General and administrative 1,459 1,326 Total $ 2,162 $ 1,610 For the period ended March 31, 2024, approximately $ 281,000 of the stock-based compensation expense was recorded as a liability. For the period ended March 31, 2023, the Company did no t record any stock-based compensation expense as a liability. Unrecognized share-based compensation related to stock-based options amounted to $ 12.5 million at March 31, 2024 and is expected to be recognized over a weighted average period of approximately 3.21 years. Unrecognized share-based compensation related to restricted stock units amounted to $ 3.9 million at March 31, 2024 and is expected to be recognized over a weighted average period of approximately 2.6 years. In March 2024, the Company granted options to purchase 550,000 shares of common stock at an exercise price of $ 6.07 per share to its Chief Executive Officer (“2024 Performance Option”) and granted 385,000 RSUs to its Executive Chair (“2024 PSUs”), each with performance-based vesting conditions under the 2020 Plan. Vesting of the 2024 Performance Option and the 2024 PSUs are based on the achievement of various clinical and regulatory milestones during the specified periods. For the performance-based stock awards, the Company measures stock compensation expense based on the fair value of the award on the grant date and then once the Company determines the performance criteria is probable of achievement, recognizes such amount over the vesting term of the award, which is approximately 3.8 years. The Company determined the fair value of the 2024 Performance Option using the Black-Scholes option-pricing model using the following inputs: risk-free interest rate of 4.26 %, volatility of 76.82 %, expected dividend yield 0 %, and expected term of 6.0 years . The Company measured the 2024 PSUs based on the fair value of the Company’s stock on the date of grant. As of March 31, 2024, the Company has determined that 183,333 shares of common stock subject to the 2024 Performance Option and 128,333 shares of common stock underlying the 2024 PSUs are probable to vest and has recognized approximately $ 12 thousand of expense, which is included in stock-based compensation expense. As of March 31, 2024, there is $ 1.5 million of unrecognized stock compensation expense to be recognized in connection with all of the performance-based awards that are deemed to be probable as of March 31, 2024. As of March 31, 2024 , there were 761,474 shares available for grant under the 2020 Plan and 200,800 shares available for grant under the Inducement Award Plan. In April 2020, the Board of Directors adopted the Company’s 2020 Employee Stock Purchase Plan (“2020 ESPP”). As of December 31, 2023, the Company reserved 438,834 shares of common stock for issuance under the 2020 ESPP and on January 1, 2024, the shares available for issuance under the 2020 ESPP were automatically increased by 286,072 .

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Collaboration Agreement | 7. Collaboration Agreement Under the LianBio License Agreement, in order to evaluate the transaction price for purposes of ASC 606, the Company determined that the upfront payment of $ 12.0 million and the reimbursable cost of the clinical supply of LYR-210 constitute the entirety of the consideration to be included in the transaction price as of the outset of the arrangement, which was allocated to the two performance obligations as follows: $ 8.4 million to the Combined Performance Obligation and $ 3.6 million to the Development Activities Performance Obligation. In February 2022, the Company received $ 5.0 million upon achievement of the first of the development milestones related to dosing its first patient and the transaction price was adjusted by $ 5.0 million which was allocated to the two performance obligations as follows: $ 3.5 million to the Combined Performance Obligation and $ 1.5 million to the Development Activities Performance Obligation. The remaining potential milestone payments that the Company is eligible to receive were excluded from the transaction price as of March 31, 2024 , as all milestone amounts were fully constrained based on the probability of achievement. The Company and LianBio amended the LianBio License Agreement on September 26, 2022, to allow, among other things, LianBio to conduct its own Phase 3 clinical trial and adjust certain future milestones. The amendment also requires both parties to negotiate a supply agreement prior to December 31, 2023. There was a side letter executed on December 27, 2022 which extended the negotiations of a supply agreement. The amendment did not result in any change in the Company’s determination of its performance obligations under the arrangement and all future milestones remain constrained from the transaction price. The Company has determined that the contract modification did not have a material impact on the allocation of the transaction price to the two performance obligations. LianBio announced that in October 2023 its Board of Directors commenced a comprehensive strategic review of its business. The LianBio Board ultimately concluded that selling off assets and winding down operations was the best way to realize maximum shareholder value. LianBio reported that a substantial portion of the wind down activities, including fulfillment of transition service obligations under its existing agreements and gradual cessation of currently active clinical trials, will be completed by the end of 2024. LianBio announced in 2024 that it was further reducing the size of its workforce to approximately 50 employees with plans to reduce that number further over the course of 2024. LianBio stated it will maintain a core group of employees necessary to implement an orderly wind down and support its efforts to maximize the value of its remaining business and assets including the collaboration with the Company. Due to these developments, the future of the Company’s collaboration with LianBio is uncertain as LianBio continues its wind down, while seeking a third party to acquire LianBio’s rights under the LianBio License Agreement. The Company will recognize the revenue associated with the Combined Performance Obligation as the clinical supply of LYR-210 is delivered. The Company recognizes revenue associated with the Development Activities Performance Obligation as the development activities are performed using an input method, according to the costs incurred as to the development activities related to the global Phase 3 clinical trial and the costs expected to be incurred in the future to satisfy the performance obligation. The transfer of control occurs over this time period and, in management’s judgment, is the best measure of progress towards satisfying the performance obligation. The amounts received that have not yet been recognized as revenue are deferred as a contract liability on the Company’s consolidated balance sheet and will be recognized as the clinical supply of LYR-210 is delivered and over the remaining time it takes to conduct the global Phase 3 clinical trial, respectively. There were no changes in the transaction price from December 31, 2023 to March 31, 2024 . The followi ng table reflects the transaction price (in thousands): As of March 31, 2024 Post-Milestone Combined Performance Obligation $ 11,862 Development Activities Performance Obligation 5,138 Total $ 17,000 The following table reflects the revenue recognized related to each of the performance obligations and the remaining deferred revenue (in thousands): As of March 31, 2024 Combined Performance Obligation Development Activities Performance Obligation Total Deferred revenue at December 31, 2022 $ 11,748 $ 3,604 $ 15,352 Revenue recognized — ( 1,558 ) ( 1,558 ) Deferred revenue at December 31, 2023 11,748 2,046 13,794 Revenue recognized — ( 532 ) ( 532 ) Deferred revenue at March 31, 2024 $ 11,748 $ 1,514 $ 13,262 Development and regulatory milestone fees, which are a type of variable consideration, are recognized as revenue to the extent that it is probable that a significant reversal will not occur. Note that the allocated deferred revenue associated with the clinical supply agreement has been recorded as long term deferred revenue given the potential uncertainty of delivery within the next twelve months. Entities affilia ted with Perceptive Advisors, LLC are shareholders of both the Company and LianBio. Additionally, two of the Company’s directors are Managing Directors at Perceptive Advisors, LLC and one of these directors is also the Executive Chairman of LianBio’s board of directors. |

Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standard Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). In management’s opinion, these unaudited condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s condensed consolidated financial statements for the periods presented. |
Comprehensive Loss | Comprehensive Loss Comprehensive loss includes net loss as well as other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. For the three months ended March 31, 2024 and 2023, other comprehensive income (loss) consisted of unr ealized gains and losses, net of taxes from its short-term investments. |
Restricted Cash | Restricted Cash The Company had restricted cash of approximately $ 2.0 million as of March 31, 2024 and approximately $ 1.4 million as of December 31, 2023. These balances were held as of March 31, 2024 at one of the Company’s financial institutions to secure the Company’s letters of credit for its facility leases. The Company’s statements of cash flows include restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on such statements. A reconciliation of the cash, cash equivalents, and restricted cash reported within the balance sheet that sum to the total of the same amounts shown in the statement of cash flows is as follows: March 31, December 31, 2024 2023 Cash and cash equivalents $ 15,799 $ 22,353 Restricted cash 1,992 1,392 Total $ 17,791 $ 23,745 |
Net Loss per Share | Net Loss per Share The Company has reported losses since inception and has computed basic net loss per share attributable to common stockholders by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities. The Company has included pre-funded warrants in its computation of basic net loss per share based on the nominal exercise price. The Company applies the two-class method to calculate its basic and diluted net loss per share, as the Company has issued shares that meet the definition of participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. The Company’s participating securities contractually entitle the holders of such shares to participate in dividends, but do not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, such losses are not allocated to such participating securities. Additionally, in periods in which the Company reports a net loss, diluted net loss per share is the same as basic net loss per share, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The following table sets forth the potentially dilutive securities that have been excluded from the calculation of diluted net loss per share because to include them would be anti-dilutive (in common stock equivalent shares): Three Months Ended 2024 2023 Stock options 8,053,774 5,495,826 Common stock warrants 8,606,303 — Restricted stock units 1,061,029 260,616 Total 17,721,106 5,756,442 |
Recently Issued Accounting Pronouncements | Recently Issued 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 Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. Effective January 1, 2024, the Company, as required, adopted ASU No. 2023-07, Segment Reporting (Topic 280) (“ASU 2023-07”) Improvements to Reportable Segment Disclosure for its annual financial statements and notes thereto for the year ending December 31, 2024 to be included in its 2024 Annual Report on Form 10-K. The Company is not required to adopt the standard for interim periods until the first quarter of 2025. This standard requires disclosure of significant segment expenses that are regularly provided to the CODM and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items to reconcile to segment profit or loss and the title and position of the entity's CODM. The Company will include the required disclosure information in the notes to the financial statements for the year ending December 31, 2024 included in its 2024 Annual Report on Form 10-K and is required apply ASU No. 2023-07 on a retrospective basis. The adoption of ASU No. 2023-07 will include expanded disclosure for its 2024 financial statements, but the Company does not expect that there will be a material impact to the financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to provide enhancements to annual income tax disclosures. In particular, the standard will require more detailed information in the income tax rate reconciliation, as well as the disclosure of income taxes paid disaggregated by jurisdiction, among other enhancements. The standard is effective for years beginning after December 15, 2024 and early adoption is permitted. The Company is currently evaluating the impact of the standard on the presentation of its consolidated financial statements and footnotes. Effective January 1, 2023, the Company adopted Accounting Standards Update (ASU) No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). ASU 2016-13 requires that credit losses be reported as an allowance using an expected losses model, representing the entity’s current estimate of credit losses expected to be incurred. For available-for-sale debt securities with unrealized losses, this standard now requires allowances to be recorded instead of reducing the amortized cost of the investment. The adoption of ASU 2016-13 did not have a material impact on its consolidated financial statements. |

Deferred revenue, description | Under the LianBio License Agreement, in order to evaluate the transaction price for purposes of ASC 606, the Company determined that the upfront payment of $12.0 million and the reimbursable cost of the clinical supply of LYR-210 constitute the entirety of the consideration to be included in the transaction price as of the outset of the arrangement, which was allocated to the two performance obligations as follows: $8.4 million to the Combined Performance Obligation and $3.6 million to the Development Activities Performance Obligation. In February 2022, the Company received $5.0 million upon achievement of the first of the development milestones related to dosing its first patient and the transaction price was adjusted by $5.0 million which was allocated to the two performance obligations as follows: $3.5 million to the Combined Performance Obligation and $1.5 million to the Development Activities Performance Obligation. The remaining potential milestone payments that the Company is eligible to receive were excluded from the transaction price as of March 31, 2024, as all milestone amounts were fully constrained based on the probability of achievement. | ||
