Pharmacology
Complement C5 inhibitor; eculizumab-aeeb is a recombinant humanized monoclonal IgG2/4kappa antibody that specifically binds complement protein C5 with high affinity, inhibiting its cleavage to C5a and C5b and preventing generation of the terminal complement complex C5b-9, thereby inhibiting terminal complement-mediated intravascular hemolysis in PNH and complement-mediated thrombotic microangiopathy in aHUS.
Efgartigimod alfa-fcab is a human IgG1 antibody fragment that binds to the neonatal Fc receptor (FcRn), reducing circulating IgG levels and AChR autoantibody levels in patients with generalized myasthenia gravis.
