FDA Accepts REGEN-COV® (casirivimab and imdevimab) for Priority Review for Treatment and Prophylaxis of COVID-19


TARRYTOWN, N.Y., Oct. 14, 2021 /PRNewswire/ -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that the U.S. Food and Drug Administration (FDA) has accepted for priority review a Biologics License Application (BLA) for REGEN-COV® (casirivimab and imdevimab) to treat COVID-19 in non-hospitalized patients and as prophylaxis in certain individuals. The FDA has assigned a target action date of April 13, 2022 and informed us that they currently are planning to hold an advisory committee meeting to discuss this application in advance of that date.

The BLA is supported by two positive Phase 3 trials involving more than 6,000 patients that evaluated the efficacy and safety of REGEN-COV to treat non-hospitalized patients already infected with SARS-CoV-2, and to prevent symptomatic infection in asymptomatic household contacts of SARS-CoV-2 infected individuals (both uninfected and infected contacts). A second BLA submission focusing on the treatment of patients hospitalized due to COVID-19 is expected to be submitted later this year.

Regulatory submissions are also progressing in the European Union (EU). Earlier this week, the European Medicines Agency (EMA) accepted for review the Marketing Authorization Application for the same antibody cocktail, known as Ronaprevetm in the EU and other countries outside of the U.S., for use in certain people either as a treatment in infected non-hospitalized patients, or as prophylaxis. The submission approach for the EMA is similar to that used for the FDA, with a Type II Variation planned in those already hospitalized because of COVID-19.

In the U.S., REGEN-COV has not been approved by the FDA, but is currently authorized under an Emergency Use Authorization (EUA) to?treat people with mild to moderate COVID-19 who are at high risk of serious consequences from COVID-19 infection who are either already infected (non-hospitalized) or in certain?post-exposure prophylaxis?settings. REGEN-COV is available for free to?eligible people as part of a?U.S.?government funded program, and in September Regeneron announced a new agreement with the U.S. government to supply an additional 1.4 million 1,200 mg doses of REGEN-COV by January 2022. Information on how to access REGEN-COV throughout the U.S. is available from the Department of Health and Human Services and the National Infusion Center Association.

The development and manufacturing of REGEN-COV have been funded in part with federal funds from the Biomedical Advanced Research and Development Authority, part of the U.S. Department of Health and Human Services' Office of the Assistant Secretary for Preparedness and Response, under OT number: HHSO100201700020C.

About the REGEN-COV Antibody Cocktail
REGEN-COV (casirivimab and imdevimab) is a cocktail of two monoclonal antibodies that was designed specifically to block infectivity of SARS-CoV-2, the virus that causes COVID-19, using Regeneron's proprietary VelocImmune® and VelociSuite® technologies. The two potent, virus-neutralizing antibodies that form the cocktail bind non-competitively to the critical receptor binding domain of the virus's spike protein, which diminishes the ability of mutant viruses to escape treatment and protects against spike variants that have arisen in the human population, as detailed in Cell and Science.

Multiple analyses have shown that the antibody cocktail retains potency against the main variants of concern, including Delta (first identified in India), Gamma (first identified in Brazil), Beta (first identified in South Africa) and Mu (first identified in Colombia), with information available in the Fact Sheet for Healthcare Providers. Regeneron will continue actively monitoring the potency of REGEN-COV against emerging variants. 

REGEN-COV has not been approved by the FDA, but is currently authorized for emergency use for the treatment and post-exposure prophylaxis in certain high risk individuals. Post-exposure prophylaxis with REGEN-COV is not a substitute for vaccination against COVID-19. REGEN-COV is not authorized for pre-exposure prophylaxis for prevention of COVID-19 or for use in patients who are hospitalized due to COVID-19 or require oxygen therapy, or for people currently using chronic oxygen therapy because of an underlying comorbidity who require an increase in baseline oxygen flow rate due to COVID-19. This authorization is for the duration of the declaration that circumstances exist justifying the authorization of the emergency uses under section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner. Additional information about REGEN-COV in the U.S. is below (authorized uses and important safety information).

REGEN-COV is an investigational medicine that has emergency or temporary pandemic authorizations currently in place in more than?40?countries, including the U.S., several countries in the EU, India, Switzerland and Canada, and?the antibody cocktail?is?fully approved in Japan and conditionally approved in the UK.

Regeneron invented REGEN-COV and is collaborating with Roche to increase global supply, with Roche primarily responsible for development and distribution outside the U.S. Regeneron and Roche share a commitment to making the antibody cocktail available around the globe and will support access in low- and lower-middle-income countries through drug donations to be made in partnership with public health organizations.

About Regeneron's VelocImmune Technology
Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create approximately a quarter of all original, FDA-approved fully human monoclonal antibodies currently available. This includes REGEN?COV® (casirivimab and imdevimab), Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb) and Inmazebtm (atoltivimab, maftivimab and odesivimab-ebgn).
