Nature of the Business and Basis of Presentation	1. Nature of the Business and Basis of Presentation Invivyd, Inc. (together with its consolidated subsidiaries, the “Company”), is a biopharmaceutical company devoted to delivering protection from serious viral infectious diseases, beginning with SARS-CoV-2. The Company’s proprietary INVYMAB™ platform approach combines state-of-the-art viral surveillance and predictive modeling with advanced antibody engineering. INVYMAB is designed to facilitate the rapid, serial generation of new monoclonal antibodies (“mAbs”) to address evolving viral threats. On March 22, 2024, the Company received emergency use authorization (“EUA”) from the U.S. Food and Drug Administration (“FDA”) for PEMGARDA™ (pemivibart) injection, for intravenous use, a half-life extended investigational mAb, for the pre-exposure prophylaxis (prevention) of COVID-19 in adults and adolescents (12 years of age and older weighing at least 40 kg) who have moderate-to-severe immune compromise due to certain medical conditions or receipt of certain immunosuppressive medications or treatments and are unlikely to mount an adequate immune response to COVID-19 vaccination. Recipients should not be currently infected with or have had a known recent exposure to an individual infected with SARS-CoV-2. In May 2024, the Company announced its intention to submit an EUA application to the FDA for pemivibart for the treatment of mild to moderate symptomatic COVID-19 in certain immunocompromised people utilizing a rapid immunobridging pathway, which was aligned in principle with the FDA and would leverage a similar approach as the Company used to achieve its current EUA for PEMGARDA for pre-exposure prophylaxis of COVID-19 in certain immunocompromised people. The immunobridging pathway for COVID-19 treatment is enabled by data from the Company’s previous Phase 2/3 clinical trial (STAMP) of adintrevimab, the prototype mAb, for the treatment of COVID-19 and data from the Company’s ongoing CANOPY Phase 3 clinical trial of VYD222 (pemivibart) for pre-exposure prophylaxis of COVID-19. The potential COVID-19 treatment EUA request would focus on the critical treatment needs of people in the U.S. who have moderate-to-severe immune compromise and for whom alternative COVID-19 treatment options are not clinically appropriate or accessible. Subsequent to the anticipated submission of an EUA request, the Company plans to initiate a compact clinical trial focused on confirmatory safety, pharmacokinetics, and clinical virology. PEMGARDA is the Company’s first mAb in a planned series of innovative mAb candidates designed to keep pace with SARS-CoV-2 viral evolution. As the SARS-CoV-2 virus evolves over time, the Company anticipates leveraging its INVYMAB platform approach to periodically introduce new or engineered mAb candidates, an approach that would be analogous to the periodic updates made to influenza and COVID-19 vaccines. In January 2024, the Company nominated VYD2311, a mAb optimized for neutralization potency against recent SARS-CoV-2 lineages such as BA.2.86 and JN.1, as a drug candidate, and the Company expects it will be the next pipeline program to advance into clinical development. In addition to developing candidates for COVID-19, the Company expects to apply its INVYMAB platform approach to produce lead molecules for other viral diseases, such as influenza. The Company was incorporated in the State of Delaware in June 2020. The Company operates as a hybrid company with employees working at its corporate headquarters in Waltham, Massachusetts and remotely. In June 2022, and subsequently amended in September 2022, the Company entered into a lease for dedicated laboratory and office space in Newton, Massachusetts for research and development purposes. In 2022, the Company expanded its research team in order to enable internal discovery and development of its mAb candidates, while continuing to leverage the Company’s existing partnership with Adimab, LLC (“Adimab”). The Company is focused on antibody discovery and use of Adimab’s platform technology while building its own internal capabilities. In addition, the Company performs research and development activities internally and engages third parties, including Adimab, to perform ongoing research and development and other services on its behalf. The Company is subject to a number of risks and uncertainties common to companies in the biopharmaceutical industry, including, but not limited to, completing clinical trials, the ability to raise additional capital to fund operations, obtaining regulatory authorization or approval for product candidates, risks associated with market acceptance and commercialization of products, competition from other products, protection of proprietary intellectual property, compliance with government regulations, dependence on key personnel, the ability to attract and retain qualified employees, and reliance on third-party organizations for the discovery, manufacturing, clinical and commercial success of its product candidates. Through March 31, 2024, the Company had not generated any revenue. To date, the Company has received regulatory authorization for only one product candidate, PEMGARDA, which has not been approved, but has been authorized for emergency use by the FDA under an EUA, for pre-exposure prophylaxis of COVID-19 in certain adults and adolescent individuals (12 years of age and older weighing at least 40 kg). Beyond VYD222 (pemivibart), all of the Company’s other product candidates, other than adintrevimab, are currently in preclinical development. The Company’s additional product candidates require significant additional research and development efforts, including extensive clinical testing, and regulatory authorization or approval prior to potential commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure and compliance-reporting capabilities. It is uncertain when, if ever, the Company will generate substantial revenue from product sales to be able to fund its operating expenses and capital requirements. Substantial Doubt about Ability to Continue as a Going Concern The accompanying condensed consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets, and the satisfaction of liabilities and commitments in the ordinary course of business. The Company has primarily funded its operations with proceeds from sales of convertible preferred stock, proceeds from the Company’s initial public offering (“IPO”) and net proceeds received from shares of common stock solder under the Sales Agreement (defined below). In February 2024, the Company sold 9,000,000 shares of its common stock under the Sales Agreement at an average price of $4.50 per share for $39.3 million in net proceeds. The Company has incurred losses and negative cash flows from operations since its inception, including a net loss of $43.5 million for the three months ended March 31, 2024. As of March 31, 2024, the Company had an accumulated deficit of $775.6 million. The Company may continue to generate operating losses for the foreseeable future. Based on current operating plans and excluding any contribution from revenues or external financing, the Company will not have sufficient cash and cash equivalents to fund its operating expenses and capital requirements beyond one year from the issuance of these condensed consolidated financial statements, and therefore, the Company has concluded that there is substantial doubt about its ability to continue as a going concern. The Company will require additional funding through a combination of contribution from revenues, equity offerings, government or private-party grants, debt financings or other capital sources, such as collaborations with other companies, strategic alliances or licensing arrangements to finance its future operations. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaborations or other arrangements. The terms of any financing may adversely affect the holdings or rights of the Company’s stockholders. If the Company is unable to obtain sufficient capital, the Company will 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. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.
