Active Idiopathic Inflammatory Myopathy (IIM) research hub

A Phase 2/3, Randomized, Double-Blinded, Placebo-Controlled, Parallel-Group, 2-Arm, Multicenter, Operationally Seamless Study to Evaluate the Efficacy, Safety, Tolerability, Pharmacodynamics, Pharmacokinetics, and Immunogenicity of Efgartigimod PH20 SC in Participants Aged 18 Years and Older With Active Idiopathic Inflammatory Myopathy

This clinical trial is testing a new injection called efgartigimod for adults with inflammatory muscle disease (myositis). Researchers want to see if the medicine can safely reduce muscle inflammation, improve strength, and help people lower their daily steroid dose compared to a dummy treatment over 52 weeks.
