What is pozelimab?
Pronunciation: /pozelimab*/
pozelimab
Definition
A human immunoglobulin G4 (IgG4) monoclonal antibody directed against terminal complement protein C5, with potential anti-inflammatory activity. Upon administration, pozelimab targets and binds to terminal complement protein C5, thereby blocking C5 cleavage into pro-inflammatory components and preventing the complement-mediated destruction of red blood cells (RBCs) as seen in paroxysmal nocturnal hemoglobinuria (PNH). C5, a complement pathway protein, is expressed at high levels by the liver.
