CHMP recommends EU approval of casirivimab and imdevimab to treat and prevent COVID-19 infection.

The positive opinion is for people aged 12 years and older for the treatment of non-hospitalized patients (outpatients) with confirmed COVID-19 who do not require oxygen supplementation and who are at increased risk of progressing to severe COVID-19, and to prevent COVID-19. A final decision from the European Commission regarding the approval of the antibody cocktail is expected in the near future.

The positive opinion is based on two positive Phase III trials involving more than 6,000 individuals that evaluated the efficacy and safety of the antibody cocktail 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).

Regeneron invented the antibody cocktail and is collaborating with Roche, who is primarily responsible for development and distribution outside the U.S. In addition to this Marketing Authorization Application, the companies intend to submit a future Type II Variation to the EMA that seeks to expand the potential indication to include the treatment of patients hospitalized because of COVID-19.
