Sotrovimab for COVID-19

42nd treatment shown to reduce risk in August 2022, now with p = 0.00067 from 28 studies, recognized in 42 countries. Efficacy is variant dependent.

Lower risk for mortality, ICU, and hospitalization.

No treatment is 100% effective. Protocols combine treatments.

5,700+ studies for 169 treatments. c19early.org

Retrospective 100 sotrovimab patients in Australia, 23 PCR+ more than 10 days post-infusion (68 with status unknown), showing rapid development of spike gene mutations that have been shown to confer high level resistance to sotrovimab in vitro.

Efficacy is variant dependent. In Vitro studies predict lower efficacy for BA.11-3, BA.4, BA.54, XBB.1.9.3, XBB.1.5.24, XBB.2.9, CH.1.15, and no efficacy for BA.26, XBB, XBB.1.5, ХВВ.1.9.17, XBB.1.16, BQ.1.1.45, and CL.15. US EUA has been revoked.

ABSTRACT (100 words) Several Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) neutralising monoclonal antibodies (mAbs) have received emergency use authorisation by regulatory agencies for treatment and prevention of Coronavirus Disease 2019 (COVID-19), including in patients at risk for progression to severe disease. Here we report the persistence of viable SARS-CoV-2 in patients treated with sotrovimab and the rapid development of spike gene mutations that have been shown to confer high level resistance to sotrovimab in vitro. We highlight the need for SARS-CoV-2 genomic surveillance in at risk individuals to inform stewardship of mAbs use and prevent potential treatment failures. medRxiv preprint doi: https://doi.org/10.1101/2021.12.18.21267628; this version posted December 21, 2021.
