Viral evolution was evaluated in 47 immunocompromised patients treated with sotrovimab. Sequencing of SARS-CoV-2 following therapy was successful in 16. Mutations associated with sotrovimab resistance were documented in 6; viral replication continued after 30 days in 5. Combination antibody therapy may be required to avoid acquired resistance in immunocompromised patients.
对 47 名接受索特罗维单抗治疗的免疫功能低下患者的病毒进化情况进行了评估。16 例患者的治疗后 SARS-CoV-2 测序成功。6 例患者中记录了与索特罗维单抗耐药相关的突变;5 例患者在 30 天后病毒仍持续复制。免疫功能低下患者可能需要联合抗体治疗以避免获得性耐药。
