Retrospective 30,247 outpatients in the USA, showing no significant differences with sotrovimab with omicron BA.1.
Efficacy is variant dependent. In Vitro studies predict lower efficacy for BA.1 Liu, Sheward, VanBlargan and a lack of efficacy for BA.2 Zhou. US EUA has been revoked.
risk of death, 38.0% lower, RR 0.62, p = 0.62, treatment 1 of 1,542 (0.1%), control 7 of 3,663 (0.2%), odds ratio converted to relative risk.
risk of hospitalization, 17.5% lower, RR 0.82, p = 0.32, treatment 39 of 1,542 (2.5%), control 116 of 3,663 (3.2%), NNT 157, odds ratio converted to relative risk, primary outcome.
risk of progression, 2.8% higher, RR 1.03, p = 0.83, treatment 93 of 1,542 (6.0%), control 224 of 3,663 (6.1%), NNT 1189, odds ratio converted to relative risk, ED visit.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
