Myasthenia Gravis Treatment Market Size & Share 2025 - 2034

Myasthenia Gravis Treatment Market Size

The global myasthenia gravis treatment market size was valued at USD 1.8 billion in 2024. The market is expected to grow from USD 1.9 billion in 2025 to USD 3.8 billion in 2034, at a CAGR of 7.6%. The rapid surge in the number of myasthenia gravis cases is driving the demand for effective treatment options.

For instance, according to the Myasthenia Gravis Foundation of America, approximately 150 to 200 people out of every one million population globally are affected by myasthenia gravis. This high volume of cases is highlighting the urgent need for effective treatment options for disease management and prevention, thereby driving the market growth.
 

In addition, rising awareness towards disease, surging investment into healthcare systems, alongside advancements in diagnostic systems, are boosting the early detection and diagnosis rate of myasthenia gravis, thus, increasing the necessity for its timely treatment. Furthermore, the rapidly increasing elderly population, that is vulnerable to autoimmune disorders, further adds to the prevalence of myasthenia gravis. For instance, according to the United Nations, there were approximately 830 million individuals aged 65 years and older, globally, in 2024. This number was expected to grow substantially to reach 1.7 billion by 2054. Therefore, this rapidly growing aging population, having high risk of myasthenia gravis contraction, is driving the market growth.
 

Furthermore, increasing investments in research and development by pharmaceutical organizations is promoting the development and introduction of advanced treatments such as monoclonal antibodies, corticosteroids, and immunosuppresants for the treatment of myasthenia gravis, further aiding the market growth. For instance, in October 2023, ZILBRYSQ (zilucoplan) developed by UCB, received an approval from the United States FDA in October 2023 for treating myasthenia gravis in adults.
 

Myasthenia Gravis Treatment Market Trends

• The market is witnessing a tremendous shift towards novel advanced treatment options such as FcRn inhibitors and monoclonal antibodies, away from conventional treatments such as immunosuppressants and corticosteroids. Treatments such as efgartigimod (Vyvgart), ravulizumab (Ultomiris), and eculizumab (Soliris) have gained significant market traction due to their limited side effects and long-term relief.
