| Description | CR8020 is a broadly neutralizing antibody (bNAb) targeting the stem region of influenza A virus (IAV) hemagglutinin (HA) and is in phase II trials for prophylactic use against group 2 IAVs. Structural and computational analyses show that CR8020 binds HA residues subject to antigenic drift and host selection pressure, with escape mutations observed in some H7N9 strains. Additionally, effective engagement of Fcγ receptors (FcγR) is crucial for antibody efficacy, but membrane steric hindrance may limit HA-CR8020-FcγR complex formation. These findings highlight epitope mutability and immune complex accessibility as key factors in bNAb development. |
