Regeneron Pharmaceuticals announced that the antibody cocktail casirivimab and imdevimab administered together, a therapy currently being investigated for use in COVID-19, has received Emergency Use Authorization from the Food and Drug Administration. Casirivimab and imdevimab administered together are authorized for the treatment of mild to moderate COVID-19 in adults, as well as in pediatric patients at least 12 years of age and weighing at least 40 kg, who have received positive results of direct SARS-CoV-2 viral testing and are at high risk for progressing to severe COVID-19 and/or hospitalization. “The clinical evidence from Regeneron’s outpatient trial suggests that monoclonal antibodies such as REGEN-COV2 have the greatest benefit when given early after diagnosis and in patients who have not yet mounted their own immune response or who have high viral load,” Regeneron said in a statement. Regeneron expects to have REGEN-COV2 treatment doses ready for approximately 80,000 patients by the end of November, approximately 200,000 patients by the first week of January, and approximately 300,000 patients in total by the end of January 2021. REGEN-COV2 continues to be evaluated in Phase 2/3 clinical trials for the treatment of COVID-19 in certain hospitalized and non-hospitalized patients, the Phase 3 open-label RECOVERY trial of hospitalized patients in the UK, and a Phase 3 trial for the prevention of COVID-19 in household contacts of infected individuals. To date, more than 7,000 people have participated in REGEN-COV2 clinical trials.
