Myasthenia Gravis

Also known as MG, autoimmune neuromuscular junction disorder, AChR antibody positive MG

Myasthenia gravis is an autoimmune disease in which antibodies attack proteins at the neuromuscular junction - most commonly the acetylcholine receptor (AChR) or muscle-specific kinase (MuSK). This disrupts nerve-to-muscle signaling, causin

About Myasthenia Gravis

Myasthenia gravis is an autoimmune disease in which antibodies attack proteins at the neuromuscular junction - most commonly the acetylcholine receptor (AChR) or muscle-specific kinase (MuSK). This disrupts nerve-to-muscle signaling, causing fluctuating muscle weakness that worsens with activity and improves with rest. It is highly treatable with cholinesterase inhibitors, immunosuppressants, and newer complement inhibitors like eculizumab.

Before you apply

Things trial teams commonly ask about for Myasthenia Gravis. Not eligibility rules; those are set by each study.

  • Antibody status (AChR-positive, MuSK-positive, or seronegative) is the most critical eligibility factor
  • MGFA clinical classification (Class I through V) and QMG score are standard trial entry criteria
  • Thymoma status and prior thymectomy are required safety screens in most trials
