Mechanism-Driven gMG Therapy: FcRn Antagonists and the Rise of Precision Neurology

Faculty: Neelam Goyal, MD


Faculty: Christyn Edmundson, MD

This Clinical Countdown addresses key challenges in diagnosing and managing generalized myasthenia gravis (gMG), with a focus on FcRn antagonists. Drs. Edmundson and Goyal review diagnostic challenges in gMG, along with the mechanism of FcRn blockade and how it compares to traditional therapies such as corticosteroids, IVIG, and plasma exchange. The discussion highlights pivotal phase 3 trials (ADAPT, MycarinG, and VIVACITY MG), evaluating differences in efficacy, dosing schedules, and administration routes for agents like efgartigimod, rozanolixizumab, and nipocalimab. Faculty discuss how data from these trials informs individualized treatment planning and facilitates shared decision-making.
