A Study to Evalute the Efficacy and Safety of Efgartigimod PH20 Subcutaneous in Adult Patients with Primary Immune Thrombocytopenia (ADVANCE SC)

Argenx BVBA is conducting a phase 3, multicenter, randomized, double-blinded, placebo-controlled trial to evaluate the efficacy and safety of efgartigimod (ARGX 113), PH20 administered subcutaneously. This is a specially formulated antibody depletion therapy which is a human IgG Fc fragment that targets and binds to the neonatal Fc receptor (FcRn) to increase IgG clearance and block IgG recycling in the body. IgG antibodies accelerate platelet clearance and destruction, and also interfere with proper platelet production. Eligibility is restricted to adult patients 18 years of age or older who have persistent or chronic ITP and a platelet count lower than 30 x 109/L.
