Invivyd Announces Receipt of Twelve Months’ Advanced Notice of Emergency Use Authorization (EUA) Termination for PEMGARDA® and Provides an Update on Next Steps with the U.S. FDA
- U.S. Department of Health and Human Services (HHS) announced advanced Notice of Termination of the COVID-19 EUA declaration, effective June 29, 2027
- Consequently, Invivyd received from the U.S. Food and Drug Administration (FDA) Notice of Termination of the PEMGARDA EUA, to be effective on June 29, 2027, after a twelve-month transition period
- Consistent with EUA transition processes, Invivyd is in dialogue with FDA about appropriate next steps for PEMGARDA
- Invivyd intends to pursue every avenue to secure permanent, high quality medical protection from COVID infection for immune-compromised and other vulnerable Americans
-
PEMGARDA has demonstrated strong protection from COVID in a contemporary randomized clinical trial, has been growing in clinical use for more than two years, and is a critical non-vaccine option for vulnerable Americans that combines high antiviral activity and attractive safety demonstrated in clinical trials and post-authorization monitoring
NEW HAVEN, Conn., July 06, 2026 (GLOBE NEWSWIRE) -- Invivyd, Inc. (Nasdaq: IVVD) today announced that the U.S. Food and Drug Administration (FDA) has sent Invivyd a Notice of Termination for the PEMGARDA® (pemivibart) Emergency Use Authorization (EUA), following the U.S. Department of Health and Human Services’ (HHS) announcement of advanced Notice of Termination of the COVID-19 EUA declaration on June 30, 2026 (link), with an effective date of June 29, 2027. Consequently, the EUA for PEMGARDA is set to terminate on June 29, 2027. PEMGARDA (pemivibart) is Invivyd’s investigational monoclonal antibody authorized by the FDA under an EUA since March 2024 for the pre-exposure prophylaxis (prevention) of COVID-19 in certain adults and adolescents 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.
The Secretary of HHS is obligated by law under Section 564(b)(5) of the Federal Food, Drug, and Cosmetic Act, codified as 21 U.S.C. § 360bbb-3(b)(5), (link) to provide sponsors such as Invivyd written notice of potential obstacles for an EUA product’s approval, including specific actions to be taken by HHS and Invivyd to overcome the same. Invivyd is in active dialogue with FDA on next steps, although, to date, neither HHS nor FDA has expressly provided Invivyd with such written advice regarding a PEMGARDA regulatory approval pathway.
“The end of a formal emergency for COVID products is in many ways overdue,” commented Marc Elia, Chairman of Invivyd’s Board of Directors. “While an EUA designation granted to PEMGARDA by the U.S. FDA in March 2024 has allowed thousands of vulnerable Americans access to a non-vaccine COVID-prevention option for over two years, the EUA designation is not a product approval. At Invivyd, we believe PEMGARDA has sufficient clinical and post-authorization data to support Biologics License Application (BLA) submission and approval, and we regret that procedural uncertainty has needlessly intruded into our work on behalf of vulnerable Americans, who may find these headlines worrying and confusing.” Mr. Elia continued, “Our view at Invivyd is unchanged over years: Invivyd’s monoclonal antibodies for COVID prevention have generated more randomized clinical data than comparable COVID-19 vaccine boosts, which have all received full approval via BLA, and we feel as though a full approval of PEMGARDA is well-warranted at this time by the totality of demonstrated safety and efficacy data both from the CANOPY pivotal trial and from growing clinical practice. We are in dialogue with the FDA on appropriate next steps.”
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, LP.8.1 and XFG. 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 the treatment of COVID-19, Long COVID, or COVID-19 Post-Vaccination Syndrome, or for 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. 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.
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 authorization revoked sooner. On June 30, 2026, the U.S. Department of Health and Human Services (HHS) announced notice of the termination of the declaration, effective June 29, 2027.
