ABSTRACT
Background:
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to spread globally and cause significant morbidity and mortality. Antispike protein monoclonal antibody (mAb) therapy has been shown to prevent progression to severe coronavirus disease 2019 (COVID-19). The objective of this study was to report the outcomes of high-risk, SARS-CoV-2-positive patients infused with 1 of the 3 mAb therapies available through Food and Drug Administration Emergency Use Authorization (EUA).Methods:
A total of 4328 SARS-CoV-2-positive patients who satisfied EUA criteria for eligibility for receiving mAb therapy were infused with bamlanivimab or the combination therapies bamlanivimab-etesevimab or casirivimab-imdevimab from November 22, 2020, to May 31, 2021, at 6 infusion clinics and multiple emergency departments within the 8 Houston Methodist Hospitals in Houston, Texas. The primary outcome of hospital admission within 14 and 28 days postinfusion was assessed relative to a propensity score-matched cohort, matched based on age, race/ethnicity, median income by zip code, body mass index, comorbidities, and positive polymerase chain reaction date. Secondary outcomes included intensive care unit admission and mortality.Results:
A total of 2879 infused patients and matched controls were included in the analysis, including 1718 patients infused with bamlanivimab, 346 patients infused with bamlanivimab-etesevimab, and 815 patients infused with casirivimab-imdevimab. Hospital admission and mortality rates were significantly decreased overall in mAb-infused patients relative to matched controls. Among the infused cohort, those who received casirivimab-imdevimab had a significantly decreased rate of admission relative to the other 2 mAb therapy groups (adjusted risk ratio,0.51; P=.001).Conclusions:
Treatment with bamlanivimab, bamlanivimab-etesevimab, or casirivimab-imdevimab significantly decreased the number of patients who progressed to severe COVID-19 disease and required hospitalization.
