艾美赛珠单抗 (Hemlibra)

概览

Emicizumab is an antibody against Factor IXa and Factor X used to treat hemophilia A.

作用机制

Emicizumab exerts its action by performing the function of the coagulation Factor VIII without presenting a structural homology. It presents a dual specificity which allows it to bind to both the Factor IXa and Factor X, performing the required bridging activity for the launch of the coagulation cascade.

适应症

The main function of Emicizumab is the prevention of bleeding episodes. Thus, Emicizumab is approved for the routine prophylaxis to prevent or reduce the frequency of bleeding episodes of adult and pediatric patients with hemophilia A with or without Factor VIII inhibitors. Hemophilia A is a deficiency of coagulation Factor VIII which causes a serious bleeding disorder. The standard treatment is done with the administration of recombinant or serum-deriver Factor VIII which induces the formation of anti-factor VIII alloantibodies (Factor VIII inhibitors) and renders the standard treatment ineffective.
