Odesivimab

Specification

• Cat#: THA-0140
• Product Name: Odesivimab
• Description: Odesivimab 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.
• Sequences: Not Available
• Molecular Weight: 146164.54 Da (Polypeptide only)
• Introduction: Ebola virus (EBOV) remains an important human pathogen within the Ebolavirus genus, having been responsible for at least 17 known outbreaks with an average case fatality rate of 43.92%. Immune therapy using monoclonal antibodies (mAbs) is becoming an increasingly attractive therapeutic method to combat infectious diseases due to its rapid development, low toxicity, and high specificity. The chief surface target of EBOV particles is the GP1,2 glycoprotein, which also appears on the surface of EBOV-infected cells, offering opportunities for both neutralizing and cytotoxic (i.e. through Fc-mediated immune effector function) antibody effects to play a role in combatting EBOV infection. A recent large-scale study elucidated that both neutralizing and Fc-mediated functions of antibodies were important for therapeutic benefit in animal models of EBOV infection. INMAZEB , formerly referred to as REGN-EB3, combines the three humanized IgG1κ mAbs Odesivimab (REGN 3471), Maftivimab (REGN 3479), and Atoltivimab (REGN 3470) in equimolar proportions. All three mAbs bind to a distinct portion of the GP1,2 glycoprotein and collectively provide neutralizing and Fc-mediated immune effector function against EBOV in vitro and protection against EBOV infection in vivo. INMAZEB is produced by Regeneron Pharmaceuticals and was granted FDA approval on October 14, 2020.

Pharmaceutical Information

• Pharmacodynamics: Odesivimab is a fully-humanized IgG1κ monoclonal antibody (mAb) directed against the GP1,2 glycoprotein that provides both neutralizing and Fc-dependent immune-mediated activity against Zaire ebolavirus. As a mAb, Odesivimab exhibits low toxicity and is generally well tolerated but does include the risk of potentially life-threatening hypersensitivity reactions.
• Targets: Envelope glycoprotein
