Real-world effectiveness of sotrovimab for the treatment of SARS-CoV-2 infection during Omicron BA. 2 and BA. 5 subvariant predominance: A systematic literature review

摘要: PurposeTo evaluate clinical outcomes associated with sotrovimab use during Omicron BA.2 and BA.5 predominance.MethodsElectronic databases were searched for observational studies published in peer-reviewed journals, preprint articles and conference abstracts from January 1, 2022 to February 27, 2023.ResultsThe 14 studies identified were heterogeneous in terms of study design, population, endpoints and definitions. They included > 1.7 million high-risk patients with COVID-19, of whom approximately 41,000 received sotrovimab (range n = 20–5979 during BA.2 and n = 76–1383 during BA.5 predominance). Four studies compared the effectiveness of sotrovimab with untreated or no monoclonal antibody treatment controls, two compared sotrovimab with other treatments, and three single-arm studies compared outcomes during BA.2 and/or BA.5 versus BA.1. Five studies descriptively reported rates …
