Amubarvimab/Romlusevimab: First Approval.

Amubarvimab /romlusevimab is a combination of two neutralizing recombinant human IgG1 monoclonal antibodies (amubarvimab and romlusevimab) against the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19). Jointly developed by Brii Biosciences, Tsinghua University and the Third People's Hospital of Shenzhen, it has been approved (in December 2021) by the National Medical Products Administration of China for the treatment of mild COVID-19 in patients aged ≥ 18 years, and those aged 12-17 years with a bodyweight of ≥ 40 kg (conditional approval) who are at high risk of progressing to severe disease, including hospitalization or death. An Emergency Use Authorization application for amubarvimab/romlusevimab is currently under review in the USA. This article summarizes the milestones in the development of amubarvimab/romlusevimab leading to this first approval for the treatment of COVID-19.
