Empasiprubart
Based on 1 Customer Validation
Empasiprubar (ARGX-117) is a humanized inhibitory monoclonal antibody targeting complement C2. Empasiprubar binds to the Sushi-2 domain of C2, preventing the formation of C3 pre convertase and inhibiting the activation of classical and lectin pathways upstream of C3 activation. Empasiprubar can prevent complement mediated autoimmune hemolytic anemia and antibody mediated organ transplant rejection. Empasiprubar can prevent neuroglial lymphoconjunctival injury in GM1 antibody mediated mouse models.

Complement C2
Empasiprubar prevents complement mediated autoimmune hemolytic anemia and antibody mediated organ transplant rejection in an in vitro model[1]. Empasiprubar can inhibit C4 downstream complement activation induced by anti-GM1 antibody binding to motor neurons (MN) derived from induced pluripotent stem cells (iPSC) model[3].
