  • FDA Limits Use of Certain Monoclonal Antibodies to Treat COVID-19 Due to the Omicron Variant (1-24-22) Due to the high prevalence of the Omicron variant REGEN-COV (casirivimab/imdevimab) and bamlanivimab/etesevimab are no longer authorized for treatment or post-exposure prophylaxis of COVID-19 in the U.S.  These monoclonal antibodies have markedly reduced activity against the omicron variant and real-time testing to identify rare non-omicron variants is not routinely available. Sotrovimab remains a recommended treatment. FDA Statement
