Generalized Myasthenia Gravis (gMG) Overview

Generalized myasthenia gravis is a chronic autoimmune disorder that disrupts communication at the neuromuscular junction, primarily driven by pathogenic antibodies attacking acetylcholine receptors. This interruption leads to fluctuating, fatigable weakness in skeletal muscles, causing debilitating symptoms like drooping eyelids, double vision, and severe difficulties speaking, swallowing, or breathing. While basic management has historically relied on acetylcholinesterase inhibitors and broad steroids, the modern therapeutic paradigm has transitioned toward highly targeted biologics. Current approaches leverage advanced complement inhibitors to block localized tissue damage and neonatal Fc receptor antagonists that accelerate the clearance of toxic antibodies. The landscape has further expanded to include newly approved B-cell depleting therapies and pipeline small interfering RNA agents designed to provide deep, durable symptom control.
