Myasthenia Gravis – Current Treatment – Detailed, Expanded Analysis (US)

Myasthenia gravis (MG) is a rare neuromuscular disorder commonly caused by autoantibodies targeting acetylcholine (ACh) receptors and therefore affecting neuromuscular synaptic transmission at the neuromuscular junction. It is a heterogenous disease; generalized MG is characterized by the presence of autoantibodies for ACh receptors; a subset of MG patients express other antibodies or are seronegative. The main symptoms are limb or respiratory muscle weakness, although some patients experience only ocular symptoms. Neurologists commonly treat MG with acetylcholinesterase inhibitors (e.g., pyridostigmine), corticosteroids, and/or immunosuppressants, mostly to manage the symptoms. The FDA has approved three biologics for MG: eculizumab (Alexion / AstraZeneca’s Soliris) in 2017, efgartigimod alfa (Argenx’s Vyvgart) in 2021, and ravulizumab (Alexion / AstraZeneca’s Ultomiris) in 2022. Understanding the many decision points that neurologists face when treating MG provides important context for the evolving market that developers will enter. This report explores neurologists’ perceptions and opinions of MG treatments, including recently launched agents.
