Etesevimab

概览

Etesevimab (LY-CoV016, also known as JS016) is a fully human and recombinant monoclonal antibody that targets the SARS-CoV-2 surface spike protein receptor binding domain. Under the EUA granted in February 2021, etesevimab is used in combination with bamlanivimab to treat mild to moderate COVID-19 in adults and pediatric patients who are at high risk for progressing to severe COVID-19: this EUA later expanded in December 2021 to include all younger children at high risk, including newborns. The EUA currently allows bamlanivimab and etesevimab for post-exposure prophylaxis of COVID-19 in adults and children.

作用机制

Etesevimab aims to neutralize SARS-CoV-2 by specifically binding to the virus' surface spike protein receptor binding domain. This high affinity binding then prevents SARS-CoV-2 from binding to the ACE2 host cell surface receptor. Etesevimab is currently being investigated against COVID-19.

适应症

Etesevimab in combination with bamlanivimab is used to treat mild to moderate coronavirus disease 2019 (COVID-19) in adults and pediatric patients, including neonates, with positive results of direct SARS-CoV-2 viral testing, and who are at high risk for progression to severe COVID-19, including hospitalization or death. This combination regimen is also used for post-exposure prophylaxis of COVID-19 in unvaccinated or immunocompromised adults and pediatric individuals, including neonates, who are at high risk of progression to severe COVID-19, including hospitalization or death.
