A study of 10,775 high-risk adult patients during the COVID-19 delta variant surge in late 2021 finds that treatment with one of three anti-spike neutralizing monoclonal antibodies for mild to moderate symptoms led to low rates of severe disease, hospitalization, ICU admission and mortality, according to Mayo Clinic researchers.
Among patients treated at Mayo Clinic in Minnesota and Wisconsin from Aug. 1 to Dec. 1, 2021, who received bamlanivimab/etesevimab, casirivimab/imdevimab or sotrovimab, 287 patients, or 2.7%, developed severe disease that led to hospitalization, oxygen supplementation or death within 30 days of treatment. The rates of severe disease were 1.2% for patients treated with bamlanivimab/etesevimab, 1.6% for patients with sotrovimab, and 2.9% for casirivimab-imdevimab.
