On July 30, 2021, the US Food and Drug Administration (FDA) authorized an additional use for the COVID-19 monoclonal antibody therapy REGEN-COV (casirivimab and imdevimab). The REGENCOV Emergency Use Authorization (EUA) has been expanded to include post-exposure prophylaxis. This new authorization is in addition to the prior authorization of REGEN-COV to treat non-hospitalized patients with mild to moderate COVID-19 in adult and pediatric patients, age 12 and older, with positive results of a direct SARS-CoV-2 viral test, and who are at high risk for progression to severe COVID-19, including hospitalization or death.
REGEN-COV is expected to be effective against circulating variants, including the Delta variant. It should be noted that post-exposure prophylaxis with REGEN-COV is not a substitute for vaccination against COVID-19 and REGEN-COV is not authorized for pre-exposure prophylaxis. For both non-hospitalized treatment and post-exposure prophylaxis use, the authorized dose is 600 mg of casirivimab and 600 mg of imdevimab. For treatment of mild to moderate COVID-19, a single intravenous infusion is strongly recommended; however, subcutaneous injection may be an alternative if infusion is not feasible or would significantly delay treatment. For post-exposure prophylaxis, REGEN-COV may be administered as either subcutaneous injection or a single IV infusion. Please refer to the following links for full details about dosing and administration.
The new authorization is for post-exposure prophylaxis use:
- In adult and pediatric individuals (12 years of age and older weighing at least 40 kg) for post-exposure prophylaxis of COVID-19 in individuals who are at high risk for progression to severe COVID-19, including hospitalization or death, and are:
- Not fully vaccinated or who are not expected to mount an adequate immune response to complete SARS-CoV-2 vaccination (for example, individuals with immunocompromising conditions including those taking immunosuppressive medications) and
- Have been exposed to an individual infected with SARS-CoV-2 consistent with close contact criteria per CDC, or
- Who are at high risk of exposure to an individual infected with SARS-CoV-2 because of occurrence of COVID-19 infection in other individuals in the same institutional setting (for example, nursing homes, home health, or prisons).
