Synonyms: ZRC3308-A7
Compound class: Antibody
Comment: Masavibart (ZRC3308-A7) is a potent, humanised IgG1 monoclonal antibody (mAb) with anti-viral potential aganist SARS-CoV-2 [1]. It binds to an epitope on the receptor binding domain (RBD) of the virus' spike protein, and blocks the spike interaction with host ACE2. Masavibart is one component of an antibody cocktail (ZRC3308) alongside a second mAb, ZRC3308-B10. These 2 mAbs bind non-overlapping spike RBD epitopes. ZRC3308 cocktail is effective against infection by the B.1.1.7 (Alpha), B.1.351 (Beta), B.1.617.2 (Delta), and AY.1 variants in vitro. In vivo efficacy has been demonstrated in the Syrian hamster SARS-CoV-2 infection model.
