Sotrovimab, sold under the brand name Xevudy, is a human neutralizing monoclonal antibody with activity against severe acute respiratory syndrome coronavirus 2, known as SARS-CoV-2.
[18] In April 2020, Lawrence Berkeley National Laboratory conducted a X-ray crystallography study at Vir's request to investigate how such antibodies bind to SARS-CoV-2 at the molecular level.
[citation needed] An interim analysis of this study reported that sotrovimab reduced the risk of hospitalization for more than 24 hours or death by 85% compared with placebo.
[24] In January 2022, the spread of the SARS-CoV-2 Omicron variant began to render other monoclonal antibodies obsolete and caused global demand for sotrovimab to skyrocket.
[24] In response, Vir and GlaxoSmithKline announced they were working with Samsung Biologics on manufacturing sotrovimab at an additional site in South Korea.
It concluded that sotrovimab can be used to treat confirmed COVID-19 in adults and adolescents (aged twelve years and above and weighing at least 40 kilograms (88 lb)) who do not require supplemental oxygen and who are at risk of progressing to severe COVID-19.
[10][26][27] In May 2021, the U.S. Food and Drug Administration (FDA) issued an emergency use authorization (EUA) for sotrovimab for the treatment of mild-to-moderate COVID-19 in people aged twelve years and above weighing at least 40 kilograms (88 lb) 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.
