Efgartigimod
Efgartigimod is designed as a first-in-class investigational antibody fragment to target the neonatal Fc receptor (FcRn). Efgartigimod is being evaluated for the treatment of patients with severe autoimmune diseases with confirmed presence of pathogenic immunoglobulin G, IgG autoantibodies, where a severe unmet medical need exists.
