Regeneron Pharmaceuticals announced that the 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 Ronapreve™ 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.
