Pharmacology
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.
Eculizumab is a monoclonal 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, complement-mediated thrombotic microangiopathy in aHUS, and presumed reduction of terminal complement C5b-9 deposition at the neuromuscular junction in gMG and in NMOSD.
