Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	1. Organization, 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 bioresorbable polymeric matrices designed to be administered in a brief, non-invasive, in-office procedure and intended to deliver up to 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, 2023, the Company has raised an aggregate of $350.4 million to fund its operations primarily from the equity financings, government grants and its License and Collaboration Agreement with LianBio discussed in Note 6. The Company has incurred recurring net losses since inception and has an accumulated deficit of approximately $264.9 million at March 31, 2023. The Company expects to continue to generate operating losses for the foreseeable future. At March 31, 2023, the Company had approximately $22.0 million of cash and cash equivalents and $60.7 million of short-term investments, and, due to an expected increase in certain expenditures, 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. Management has concluded that there is substantial doubt regarding its ability to continue as a going concern based on its analysis under applicable accounting standards. Based on its current business plan, the Company anticipates that its cash, cash equivalents and short-term investment balance is sufficient to fund its operating expenses and capital expenditures into mid-second quarter of 2024. The accompanying 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 expects 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 condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). 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”). The condensed consolidated financial statements have been prepared on the same basis as the audited annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of March 31, 2023 and the results of its operations and its cash flows for the three months ended March 31, 2023 and 2022. The results for the three months ended March 31, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023, any other interim periods, or any future year or period. These condensed consolidated financial statements should be read in conjunction with the audited financial statements as of and for the year ended December 31, 2022, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 29, 2023.
