The global myasthenia gravis treatment market size stood at USD 1.40 billion in 2023. The market is projected to grow from USD 1.51 billion in 2024 to USD 2.75 billion by 2032, grow at a CAGR of 7.8% during the 2024-2032 period. North America dominated the global market with a share of 49.29% in 2023.

Myasthenia gravis (MG) is a rare autoimmune disease that causes skeletal muscle weakness and fatigue due to delayed communication between nerves and muscles caused by the antibodies.With the increasing aging population, the global prevalence of the condition in recent years has increased.The prevalence rate of the condition ranges from 11 to 50 per 100,000 population. For instance, according to a 2020 article published by Value in Health Journal, the prevalence rate in Australia is around 11.7, whereas the rate in Italy is 79.9. Similarly, it is estimated that there are more than 700,000 patients suffering from this disease globally and approximately 36,000 to 60,000 patients in the U.S.

Several organizations, governing bodies, and industries are focusing on increasing the awareness of the condition among general and patient populations. For instance, Myasthenia Gravis Foundation of America (MGFA) is promoting different ways to recognize June as an awareness month for the condition. The foundation runs a campaign to heighten public awareness wherein they offer a 23-page toolkit and educate the public about the condition and the available treatment options. This leads to an increase in the patient population requiring treatment for the condition.

To cater to the increasing demand of the population, the players in the market like Argenx, CSL Behring, F. Hoffmann-La Roche Ltd., and others are increasing their efforts to develop novel drugs and therapies for the condition. For instance, the drug Efgartigimod developed by Argenx is currently under review with the U.S. FDA to treat the condition.

The outbreak of COVID-19 had an overall negative impact on the market. Patients were usually on immunosuppressive medications that made their immune system weaker. Therefore, these patients were prone to infections, including COVID-19. Due to these factors, the patient visits in hospitals and clinics were reduced significantly in 2020 during the pandemic.

  • For instance, according to the survey of National Organization for Rare Disorders (NORD) in 2020, more than 70% of the patients had their appointments canceled due to the unavailability of the physicians and around 30% of the patients had challenges accessing medical care.

However, the relaxation of lockdown restrictions and high vaccination rates, decreasing the spread of COVID-19, increased the patient visits to hospitals, which revived the rate of market growth in 2021 and 2022.

Myasthenia Gravis Treatment Market Trends

Robust Efforts by Key Players Towards Novel Therapies to Provide Lucrative Market Growth 

There is a gradual shift of the patients towards novel therapies for this disorder because of the side effects of conventional therapies. Also, with the increasing prevalence and awareness of the condition, the diagnosis rate among the population is increasing. This is resulting in an increase in the number of patients requiring treatment. This, along with the current unmet needs of the patient population, results in rising demand for novel therapeutics.

These factors boost the efforts by the companies towards research and development of the drugs for the condition and their approval. For instance, in July 2021, Alexion Pharmaceutical, Inc. announced positive results for the phase III study of Ultomiris, a humanized monoclonal antibody for generalized myasthenia gravis, and based on the results, the company plans to make regulatory filings in the U.S., EU, and Japan in early 2022.

Additionally, several key players in the market are focusing on subcutaneous Ig (SCIg) therapy for the condition due to the increasing demand for home health care among the population. For instance, CSL Behring conducted trials on subcutaneous immunoglobulin (SCIg), an investigational immune therapy for administering the condition as an injection under the skin. Furthermore, the collaborations and partnerships between key players and research institutions are leading to accelerated development of novel therapies for myasthenia gravis, as companies use their resources and expertise to bring new treatment options to the market.

Myasthenia Gravis Treatment Market Growth Factors

Rising Prevalence of Myasthenia Gravis to Augment Demand for Treatment

Globally, the condition's prevalence has increased significantly over the last several decades. This increase can be due to the rising awareness and diagnosis rate of the condition among the population in emerging and developed countries. The improving reimbursement policies for the condition in the countries is also driving the market growth.

  • Also, according to a survey conducted by The National Organization for Rare Disorders (NORD), the prevalence of this condition in the U.S.is approximately 14-40 per 100,000 individuals, which are roughly around 50,000 patients. Additionally, the prevalence of the condition in the U.K. is estimated to be 15 per 100,000 individuals, which has increased over time.

With the increasing diagnosis rate and favorable reimbursement policies for the condition, the demand for novel therapies is also increasing. This is increasing the efforts by the key players in the market to develop and gain approval for new drugs for the disease.

For instance, F. Hoffmann-La Roche Ltd has a drug in the pipeline for myasthenia gravis treatment under the trade name Enspyrng of which the filing is expected to be done in 2024. These factors are expected to drive the market during the forecast period.

Moreover, the population's age structure is also a factor that drives the market growth. According to the Eurostat report, more than one-fifth of Europe's population, i.e., 20.6%, was aged 65 and above in 2020. The population in Europe aged 80 years and above witnessed a significant increase from 5.9% to 14.6% from 2010 to 2020. According to the MDPI Journal of Clinical Medicine, the condition's incidence increases steadily with age. The highest incidence is found in the 60-89 years of age group. Thus, the prevalence of the condition is rising as the average life expectancy among the population increases.

  • According to a 2020 epidemiology of myasthenia gravis article published by Value in Health Journal, a higher prevalence of the condition was reported among the elderly population compared to younger ages. For instance, the prevalence of the condition in the U.K. in the geriatric population was 46.3 per 100,000 compared to 12 per 100,000 in younger ages.

Moreover, this rising prevalence has led to an increased focus on advances in medical technology and research to develop innovative treatments for myasthenia gravis. The development of novel diagnostic tools and therapies aids in the early detection and treatment of the condition, leading to better outcomes for patients, driving the market growth.


High Cost of Treatment and Inadequate Reimbursement Policies in Emerging Countries to Hinder Market Growth 

Specific aspects limit the market growth during the forecast period despite the increasing prevalence of the condition and the constant R&D focus; FDA approval for the drugs is the high cost of the myasthenia gravis treatment and the limited reimbursement policies.

  • For instance, in June 2023, according to the Real world study on treatment economic burden, and prevalence of myasthenia gravis in Italy, it was observed that the direct costs of myasthenia gravis (MG) were four times higher than other chronic neurological conditions.

  • For instance, in December 2023, according to the Becaris Publishing Limited, the mean myasthenia gravis related healthcare costs incurred during exacerbation episodes ranged from USD 26,078 to USD 51,120 per exacerbation for commercial patients and from USD 19,903 to USD 49,967 per exacerbation, for Medicare patients.

Moreover, the reimbursement policies in the developing regions are inadequate, leading to higher out-of-pocket expenses. This is a crucial factor determining the market's growth during the forecast period. Various healthcare organizations and authorities are now focusing on introducing and improvising reimbursement policies to diagnose and treat the condition in emerging countries.

Thus, the above factors and lack of well-established healthcare infrastructure are some of the restraining factors that are comparatively limiting the growth of the market in emerging countries.

Myasthenia Gravis Treatment Market Segmentation Analysis

Comparatively High Cost of IVIg Enabled the Segment to Account for Dominant Share

Based on drug class, the global market is segmented into cholinesterase inhibitors, corticosteroids, Immunosuppressants, IVIg, and others.

The IVIg segment held a leading share in 2023. The domination is accredited to its rising adoption among the patient population. This is because of the lower preference owing to the side effects caused by the conventional therapies. Also, IVIG treatment provides safe and effective long-term therapy for patients who are unresponsive to conventional therapies. For instance, according to the 2018 report published by the Medical Services Advisory Committee of Australia, the adoption of IVIg treatment among patients increased by 12.6% from 2016 to 2018. Along with this, higher costs and advanced research and development of the key players in the introduction of new IVIg drugs for the condition is anticipated to contribute to the segment's growth during the forecast period.

The immunosuppresants segment accounted for a substantial market share in 2023. The common immunosuppresant medications such as  azathioprine, prednisone, and mycophenolate mofetil lower the immune system, preventing the immune attack on neuromuscular junction, thereby limiting muscle fatigue. This increases the demand for immunosuppresants in the treatment of myasthenia gravis, thereby spurring the market growth.

On the other hand, the monoclonal antibodies segment is expected to grow significantly during the forecast period. The increasing prevalence of the disease among the population and the rising demand for targeted therapies for the condition are the factors that are anticipated to spur segmental growth between 2024 and 2032.
