Abstract
Background: Remdesivir and sotrovimab both have clinical trial data in the outpatient setting demonstrating reduction in the risk of hospitalizations and emergency department (ED) visits related to COVID-19.
Objectives: To evaluate the effectiveness of remdesivir in comparison with sotrovimab and matched high-risk control patients in preventing COVID-19-related hospitalizations and ED visits during the Omicron B.1.1.529 surge.
Patients and methods: This retrospective cohort study included outpatients positive for SARS-CoV-2, with non-severe symptoms for ≤7 days and deemed high-risk for severe COVID-19 by an internal scoring matrix. Patients who received remdesivir or sotrovimab from 27/12/2021 to 04/02/2022 were included (n = 82 and n = 88, respectively). These were compared with a control cohort of high-risk COVID-19 outpatients who did not receive therapy (n = 90). The primary outcome was a composite of 29 day COVID-19-related hospitalizations and/or ED visits. Pre-specified secondary outcomes included components of the primary endpoint, 29 day all-cause mortality and serious adverse drug events.
Results: Patients treated with remdesivir were significantly less likely to be hospitalized or visit the ED within 29 days from symptom onset (11% versus 23.3%; OR = 0.41, 95% CI = 0.17-0.95). Patients receiving sotrovimab were also less likely to be hospitalized or visit the ED (8% versus 23.3%; OR = 0.28, 95% CI = 0.11-0.71). There was no difference in the incidence of hospitalizations/ED visits between sotrovimab and remdesivir.
Conclusions: Our highest-risk outpatients with Omicron-related COVID-19 who received early sotrovimab or remdesivir had significantly lower likelihoods of a hospitalization and/or ED visit.
