Myasthenia Gravis Market Summary
The myasthenia gravis market size was valued at around USD 4.5 billion in 2024 and is expected to grow at a strong 10.4% CAGR through 2034. In 2024, there were an estimated 310,000 diagnosed cases of myasthenia gravis across the seven major markets (7MM), with the US accounting for roughly 137,000 cases—slightly more in males than females. Treatment has shifted toward precision immunotherapy, driven by targeted agents such as FcRn inhibitors (RYSTIGGO, VYVGART, IMAAVY) and complement inhibitors (SOLIRIS, ULTOMIRIS, ZILBRYSQ). Emerging therapies—including RNA CAR T-cell treatments, dual complement inhibitors, and BLyS/APRIL pathway blockers—aim to deliver long-term immune balance rather than short-term symptom relief. However, there remains a major unmet need for faster-acting, longer-lasting, and safer therapies, as many patients still experience delayed response, relapses, or side effects despite therapeutic advances.

Myasthenia Gravis Overview
Myasthenia gravis (MG) is a chronic autoimmune neuromuscular disorder characterized by fluctuating muscle weakness and fatigue. It occurs when the immune system mistakenly attacks communication between nerves and muscles, most commonly targeting acetylcholine receptors at the neuromuscular junction. This disruption leads to symptoms such as drooping eyelids, double vision, difficulty swallowing, impaired speech, and generalized weakness that worsens with activity and improves with rest. Myasthenia gravis affects individuals of all ages but shows a higher prevalence in younger women and older men. Diagnosis typically involves antibody testing, electromyography, and imaging to assess thymus abnormalities, which are often associated with the disease. While there is no cure, treatment options such as acetylcholinesterase inhibitors, immunosuppressants, corticosteroids, and targeted biologics like FcRn and complement inhibitors help control symptoms and improve quality of life. Advances in precision immunotherapy are further transforming long-term disease management.
Myasthenia Gravis Epidemiology
In 2024, the US recorded approximately 137,000 diagnosed myasthenia gravis cases, a number expected to rise by 2034 with better disease awareness and diagnostics. Across EU4 and the UK, Germany reported the highest prevalence at around 37,000 cases, while Spain had the lowest with about 14,000. In Germany, females made up 52% of diagnosed cases, reflecting a slight but consistent gender dominance. Regarding disease severity across EU4 and the UK, mild generalized MG (Class II) was the most common, affecting around 50,000 individuals, followed by ocular MG (Class I) at over 45,000 and moderate generalized (Class III) at more than 28,000. Severe cases (Class IV and V) remained comparatively rare, totaling under 10,000, emphasizing that most patients have milder disease.
In Japan, anti-AChR–positive patients formed the majority of gMG cases (~19,000), while anti-MuSK and double-seronegative groups accounted for smaller proportions.

Myasthenia Gravis Treatment Market
The treatment of myasthenia gravis typically involves a multi-faceted approach aimed at managing its symptoms and improving the patient’s quality of life. The cornerstone of myasthenia gravis treatment is the use of medications, most commonly acetylcholinesterase inhibitors like pyridostigmine, which enhance communication between nerve and muscle cells. Immunosuppressive drugs, such as corticosteroids, azathioprine, or mycophenolate mofetil, may also be prescribed to reduce the immune system’s attack on the neuromuscular junction.
In more severe cases or during myasthenia gravis crises, where symptoms become life-threatening, treatments like intravenous immunoglobulin (IVIG) or plasmapheresis may be employed to rapidly suppress the immune response. Additionally, some patients benefit from surgical interventions, such as thymectomy, to remove the thymus gland, which is often implicated in myasthenia gravis. It’s essential for myasthenia gravis patients to work closely with healthcare professionals to tailor their treatment plans to their specific needs, as responses to medications and therapies can vary significantly among individuals. Regular follow-up appointments and adjustments to treatment are typically necessary to effectively manage this chronic autoimmune disorder.
