Abstract
Objective: Sotrovimab, a dual-action, engineered human monoclonal antibody, has been demonstrated to significantly reduce the risk of hospitalisation and death in high-risk patients with COVID-19. Here, we describe the real-world use of, and outcomes from, sotrovimab treatment in Belgium during the Delta and Omicron waves among patients with COVID-19 at high risk of developing severe disease.
Methods: This was a multicentric, single-arm observational cohort study of non-hospitalised patients receiving outpatient sotrovimab treatment between 1 November 2021 and 2 August 2022 at nine hospitals in Belgium. The primary outcomes were all-cause and COVID-19-related hospitalisations and all-cause deaths during the 29-day acute follow-up period from first administration of sotrovimab.
Results: A total of 634 patients were included (63.4% aged < 65 years; 50.3% male). A high proportion (67.7%; n = 429/634) of patients were immunocompromised, with 36.9% (n = 234/634) actively treated for malignancy. During the 29-day acute period, 12.5% (n = 79/634) of sotrovimab-treated patients were hospitalised due to any cause (median duration 4 days; median time to hospitalisation 14 days) and 1.1% (n = 7/634) died due to any cause. The proportion of sotrovimab-treated patients experiencing COVID-19-related hospitalisation was highest during the Delta predominance and Delta/BA.1 codominance (both 6.3%) periods. During the BA.1 predominance, BA.1/BA.2 codominance and BA.2/BA.5 codominance periods, COVID-19-related hospitalisations were consistently low (all ≤2.7%).
Conclusion: This study indicated low rates of COVID-19-related hospitalisations and all-cause deaths in sotrovimab-treated patients in Belgium, including during Omicron subvariant periods, despite over two-thirds of the study population being immunocompromised.
