Casirivimab/imdevimab, sold under the brand name REGEN‑COV among others,[8][10] is a combination medicine used for the treatment and prevention of COVID‑19.[10] It consists of two human monoclonal antibodies, casirivimab and imdevimab that must be mixed together and administered as an infusion or subcutaneous injection.[12][8][10] The combination of two antibodies is intended to prevent mutational escape.[13] It is also available as a co-formulated product.[12] It was developed by the American biotechnology company Regeneron Pharmaceuticals.[14][15]

The most common side effects include allergic reactions, which include infusion related reactions, injection site reactions,[10] brief pain, weakness and others.[16]

The combination is approved under the brand name Ronapreve for medical use in Japan, the United Kingdom, the European Union, and Australia.[1][7][10][11][17][18]

In January 2022, the U.S. Food and Drug Administration (FDA) revised the authorizations for two monoclonal antibody treatments – bamlanivimab/etesevimab (administered together) and casirivimab/imdevimab – to limit their use to only when the recipients are likely to have been infected with or exposed to a variant that is susceptible to these treatments because data show these treatments are highly unlikely to be active against the omicron variant.[19]
