New York, USA, May 18, 2026 (GLOBE NEWSWIRE) -- Myasthenia Gravis Market Set to Surpass USD 16 Billion by 2036, Fueled by Rising Diagnosed Prevalence and Wave of Targeted Biologic Approvals | DelveInsight

Ramandeep Singh, senior consultant of forecasting at DelveInsight, said that several emerging therapies are poised to redefine the autoimmune treatment landscape through differentiated mechanisms, improved safety, and enhanced patient convenience. Among these, IMVT-1402 stands out as a strategically significant FcRn inhibitor candidate with the potential to establish a new benchmark by combining strong efficacy with a favorable safety profile, factors considered essential for long-term success in autoimmune indications.

On the other hand, Iptacopan’s oral administration and broad applicability across complement-mediated disorders could help it secure a differentiated position in the gMG market, particularly among patients inadequately managed with existing therapies. Additionally, Singh emphasized that remibrutinib’s convenient oral dosing and targeted, steroid-sparing approach may strengthen its appeal if clinical outcomes remain favorable. Meanwhile, Descartes-08 is viewed as a potentially transformative therapy in autoimmune neurology, with the capability to address the growing demand for safer, more durable, and patient-centric treatment options.

Key Factors Driving the Myasthenia Gravis Market Growth

Growing geriatric population leading to increase in MG market: The aging global population is contributing to the rise in MG cases, as the disease often manifests in older adults. Around 70K diagnosed prevalent cases of myasthenia gravis occurred in the age group 65 years and above in 7MM in 2025, due to increased autoimmune susceptibility and improved diagnostics, leading to greater detection and accumulation in older patients. This demographic shift is expanding the patient base and increasing the need for effective treatments.
Improved diagnosis & awareness increasing myasthenia gravis patient pool, which further boosts market: Greater physician awareness, better antibody testing (AChR, MuSK, LRP4), and access to electrodiagnostic tools have increased detection rates. Historically underdiagnosed mild or ocular cases are now more frequently identified.
Advancements in biologic myasthenia gravis therapies driving MG market growth: A range of targeted therapies has transformed the myasthenia gravis treatment market, including Neonatal Fc Receptor (FcRn) inhibitors like RYSTIGGO, VYVGART, VYVGART HYTRULO/VYVDURA, IMAAVY; complement inhibitors such as SOLIRIS and ULTOMIRIS, and the Complement C5 inhibitor ZILBRYSQ. These advances reflect a shift toward precision immunotherapy and improved patient outcomes.
Shifting myasthenia gravis treatment paradigms propelling MG market growth: The focus of treatment is shifting from short-term symptom control to restoring long-term immune balance by targeting antibody production and B-cell activity. This evolving approach, seen across autoimmune diseases, is driving innovation in the myasthenia gravis clinical trial, with candidates like RNA CAR T-cell therapy (Descartes-08), dual complement inhibitors (pozelimab + cemdisiran), and BLyS/APRIL pathway blockers (telitacicept) reflecting this myasthenia gravis market trend.
Robust myasthenia gravis clinical trial activity is expected to boost market growth: The myasthenia gravis treatment pipeline is robust and expanding, with numerous therapies in development across different stages. Key investigational drugs in clinical trials include IMVT-1402 (Immunovant/Roivant Sciences), Cladribine capsules (Merck KGaA), Remibrutinib (Novartis), Gefurulimab (Alexion AstraZeneca Rare Disease), Iptacopan (FABHALTA) (Novartis), Pozelimab + Cemdisiran (Regeneron Pharmaceuticals), Descartes-08 (Cartesian Therapeutics), KYV-101 (Kyverna Therapeutics), Claseprubart (DNTH103) (Dianthus Therapeutics), NMD670 (NMDP-01) (NMD Pharma), IM-101 (ImmunAbs), and others.

Myasthenia Gravis Market Analysis

The therapeutic landscape has evolved significantly with the introduction of targeted biologics that enable more precise intervention in underlying disease pathways.
