The research-grade biosimilar is a humanized IgG4 monoclonal antibody that targets human complement factor C1s. C1s is a serine protease that is part of the C1 complex which contains a pattern recognition receptor (C1q) and a C1s activating serine protease (C1r). Activation of C1 complex results in the formation of C3 convertase which cleaves to form C3a and C3b. Chronic activation of the complement system results in extravascular hemolysis which is responsible for the pathophysiology of anemia in cold agglutinin disease (CAD).
