Impact of monoclonal antibody treatment on hospitalization and mortality among non-hospitalized adults with SARS-CoV-2 infection
et al., medRxiv, doi:10.1101/2021.03.25.21254322 (Preprint)
Retrospective 234 patients receiving bamlanivimab and 234 matched controls, showing lower hospitalization and mortality with treatment. Greater benefit was seen with administration within 4 days of their positive COVID-19 test.Efficacy is highly variant dependent. Unlikely to be effective for omicron [Liu, Sheward, VanBlargan].
