(Nasdaq: IVVD), a biopharmaceutical company devoted to delivering protection from serious viral infectious diseases, today announced financial results for the fourth quarter and full year ended December 31, 2024, and recent business highlights. “We are pleased with the significant PEMGARDA™ revenue growth of 48% in the fourth quarter, reflecting increased provider awareness and adoption,” said Bill Duke, Chief Financial Officer of Invivyd. “We look forward to raising further awareness of PEMGARDA in the healthcare community and working to achieve near-term profitability. In parallel, we are advancing VYD2311, our next generation monoclonal antibody that has demonstrated highly promising Phase 1 clinical data and has the potential to offer an improved route of administration to protect vulnerable patient populations from COVID-19.” “With our impressive fourth quarter growth as our catalyst, we began 2025 with a newly transitioned, in-house sales force,” said Tim Lee, Chief Commercial Officer. “Vulnerable patient populations such as cancer patients, those undergoing or living with an organ transplant, and those who are on immunosuppressive therapies are at risk of the short-term and long-term systemic damage of COVID-19. With hospitalizations and deaths from COVID-19 greater than influenza and RSV combined, it’s imperative to keep COVID-19 at the forefront of the minds of vulnerable patients and their healthcare providers – including hematologists, transplant physicians, infectious disease clinicians, rheumatologists and primary care doctors.” Recent Business Highlights PEMGARDA Neutralization Data Updates Continued, neutralization activity of PEMGARDA shown against currently dominant SARS-CoV-2 variants LP.8.1, KP.3.1.1 and XEC, comprising the majority of SARS-CoV-2 variants currently circulating in the U.S. This aligns with Invivyd’s broader clinical and virology data, which have consistently demonstrated structural stability of the targeted epitope of PEMGARDA and prolonged neutralizing activity against contemporary variants.LP.8.1 in vitro neutralization data provided to the U.S. Food and Drug Administration (FDA) Regulatory Developments In February 2025, the FDA declined Invivyd’s request to expand the existing emergency use authorization of PEMGARDA to include treatment of mild-to-moderate COVID-19 for immunocompromised patients who have no alternative therapeutic options. Invivyd has submitted a response requesting that the FDA reconsider and looks forward to meeting to discuss next steps. Partnership & Awareness Campaigns The company announced collaboration with renowned professional football coach Jim Harbaugh to elevate awareness of the ongoing impact of COVID-19 and options available to vulnerable populations. Manufacturing & Supply VYD2311 commercial manufacturing has been substantially completed.Minimal manufacturing expenses expected in 2025, contributing to ongoing cost reductions​. Recent Pipeline Highlights Positive Phase 1 clinical data announced in February 2025 for VYD2311, a next-generation monoclonal antibody for COVID-19 Phase 1 clinical data, combined with antiviral assessment and COVID-19 antiviral correlate of protection data, including Invivyd's Phase 3 CANOPY clinical trial data for pemivibart, support a potentially attractive clinical profile for VYD2311.VYD2311 pooled, blinded adverse events were mild or moderate and thus far deemed unrelated to study drug or largely related to injection site reaction or infusion reactions. In February 2025, the company announced that in vitro neutralization potency of VYD2311 assessed across contemporary SARS-CoV-2 variants tested showed an average 17-fold greater neutralization potency than pemivibart. VYD2311 has also demonstrated stable epitope and clinically meaningful in vitro neutralization against LP.8.1 providing further validation of the company’s integrated technology platform’s potential to produce monoclonal antibodies with broad and durable viral protection along with improved drug properties.

This increase is primarily attributable to an increase in personnel costs and costs associated with commercialization of PEMGARDA.Net Loss and Net Loss per Share: Net loss was $169.9 million for the year ended December 31, 2024, compared to $198.6 million for the comparable period in 2023. Basic and diluted net loss per share was $1.43 for the year ended December 31, 2024, compared to $1.81 for the comparable period in 2023. About PEMGARDA PEMGARDA™ (pemivibart) is a half-life extended investigational monoclonal antibody (mAb). PEMGARDA was engineered from adintrevimab, Invivyd’s investigational mAb that has a robust safety data package and provided evidence of clinical efficacy in global Phase 2/3 clinical trials for the prevention and treatment of COVID-19. PEMGARDA has demonstrated in vitro neutralizing activity against major SARS-CoV-2 variants, including JN.1, KP.3.1.1, XEC and LP.8.1. PEMGARDA targets the SARS-CoV-2 spike protein receptor binding domain (RBD), thereby inhibiting virus attachment to the human ACE2 receptor on host cells. PEMGARDA (pemivibart) injection (4500 mg), for intravenous use is an investigational mAb that has not been approved, but has been authorized for emergency use by the U.S. FDA under an EUA 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. PEMGARDA is not authorized for use for treatment of COVID-19 or post-exposure prophylaxis of COVID-19. Pre-exposure prophylaxis with PEMGARDA is not a substitute for vaccination in individuals for whom COVID-19 vaccination is recommended. Individuals for whom COVID-19 vaccination is recommended, including individuals with moderate-to-severe immune compromise who may derive benefit from COVID-19 vaccinations, should receive COVID-19 vaccination. In individuals who have recently received a COVID-19 vaccine, PEMGARDA should be administered at least 2 weeks after vaccination. Anaphylaxis has been observed with PEMGARDA and the PEMGARDA Fact Sheet for Healthcare Providers includes a boxed warning for anaphylaxis. The most common adverse reactions included systemic infusion-related reactions and hypersensitivity reactions, local infusion site reactions, and infusion site infiltration or extravasation. For additional information, please see the PEMGARDA full product Fact Sheet for Healthcare Providers, including important safety information and boxed warning. To support the EUA for PEMGARDA, an immunobridging approach was used to determine if PEMGARDA may be effective for pre-exposure prophylaxis of COVID-19. Immunobridging is based on the serum virus neutralizing titer-efficacy relationships identified with other neutralizing human mAbs against SARS-CoV-2. This includes adintrevimab, the parent mAb of pemivibart, and other mAbs that were previously authorized for EUA. There are limitations of the data supporting the benefits of PEMGARDA. Evidence of clinical efficacy for other neutralizing human mAbs against SARS-CoV-2 was based on different populations and SARS-CoV-2 variants that are no longer circulating. Further, the variability associated with cell-based EC50 value determinations, along with limitations related to pharmacokinetic data and efficacy estimates for the mAbs in prior clinical trials, impact the ability to precisely estimate protective titer ranges. Additionally, certain SARS-CoV-2 viral variants may emerge that have substantially reduced susceptibility to PEMGARDA, and PEMGARDA may not be effective at preventing COVID-19 caused by these SARS-CoV-2 viral variants. The emergency use of PEMGARDA is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic under Section 564(b)(1) of the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. § 360bbb-3(b)(1), unless the declaration is terminated or authorization revoked sooner. PEMGARDA is authorized for use only when the combined national frequency of variants with substantially reduced susceptibility to PEMGARDA is less than or equal to 90%, based on available information including variant susceptibility to PEMGARDA and national variant frequencies. About VYD2311 VYD2311 is a novel monoclonal antibody (mAb) candidate being developed for COVID-19 to continue to address the urgent need for new prophylactic and therapeutic options. The pharmacokinetic profile and antiviral potency of VYD2311 may offer the ability to deliver clinically meaningful titer levels through more patient-friendly means such as an intramuscular route of administration. VYD2311 was engineered using Invivyd’s proprietary integrated technology platform and is the product of serial molecular evolution designed to generate an antibody optimized for neutralizing contemporary virus lineages. VYD2311 leverages the same antibody backbone as pemivibart, Invivyd’s investigational mAb granted emergency use authorization in the U.S. for the pre-exposure prophylaxis (PrEP) of symptomatic COVID-19 in certain immunocompromised patients, and adintrevimab, Invivyd’s investigational mAb that has a robust safety data package and demonstrated clinically meaningful results in global Phase 2/3 clinical trials for the prevention and treatment of COVID-19.
