Solid-organ transplant (SOT) patients are at high risk of developing severe coronavirus disease-19 . Neutralizing monoclonal antibodies that bind to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein prevent viral attachment to ACE2 receptor. When administered to immunocompetent patients in the early phase of infection, they reduce the risk of hospitalization and improved symptoms resolution. 1,2 Similar data were reported in a real-life study that included 69 immunosuppressed patients. 3 However, the proportion of SOT patients and their specific outcome were not reported. Dhand et al reported encouraging results in SOT patients given bamlanivimab monotherapy or casirivimab/imdevimab without a control group. 4,5 Herein, we compared the outcome of SOT patients who were given monoclonal antibodies to an historical control group. According to French law (Loi Jardé), anonymous retrospective studies do not require Institutional Review Board approval. In France, the use of monoclonal antibodies was approved on February 25, 2021 for immunosuppressed patients with positive SARS-CoV-2 nasopharyngeal RT-PCR, having symptoms
