Type  Antibody

Description  Maftivimab is part of a product containing three monoclonal IgG1κ antibodies directed against the GP1,2 glycoprotein of Zaire ebolavirus. Together, these three antibodies act to neutralize viral particles and to recruit immune effectors for the destruction of both viral particles and infected cells.Maftivimab is indicated in combination with Odesivimab and Atoltivimab for the treatment of Zaire ebolavirus infection in adult and pediatric patients, including neonates born to a mother who has been confirmed positive by RT-PCR for Zaire ebolavirus infection. INMAZEB™, formerly referred to as REGN-EB3, combines the three humanized IgG1κ mAbs Maftivimab (REGN 3479), Odesivimab (REGN 3471), and Atoltivimab (REGN 3470) in equimolar proportions.INMAZEB™ is produced by Regeneron Pharmaceuticals and was granted FDA approval on October 14, 2020.
