Generalized Myasthenia Gravis Treatment Market

Generalized Myasthenia Overview 

Myasthenia gravis (MG) is an autoimmune disease that occurs when the immune system attacks the body’s own tissues. In MG, that attack interrupts the connection between nerve and muscle—the neuromuscular junction. MG is characterized mostly by autoantibodies against the acetylcholine receptor (AChR-Ab) or against a receptor-associated protein called muscle-specific tyrosine kinase (MuSK-Ab).

Generalized Myasthenia Gravis Diagnosis and Treatment

This section covers the details of conventional and current medical therapies and diagnosis available in the Generalized Myasthenia Gravis market to treat the condition. It also provides the country-wise treatment guidelines and algorithms across the United States, Europe, and Japan.

DelveInsight’s Generalized Myasthenia Gravis market report thoroughly understands Generalized Myasthenia Gravis symptoms by including disease definition, symptoms, causes, physiology, and diagnosis. It also provides Generalized Myasthenia Gravis treatment algorithms and treatment guidelines for Generalized Myasthenia Gravis symptoms in the US, Europe, and Japan.

At present, the therapeutic market size of Myasthenia Gravis is mainly accounted by symptomatic treatments, including acetylcholinesterase inhibitors (Pyridostigmine), short-term immunosuppressants (corticosteroids), long-term immunosuppressant (azathioprine, cyclosporine, cyclophosphamide, methotrexate, mycophenolate mofetil, rituximab, tacrolimus), rapid-acting short- term immunomodulators (intravenous immunoglobulin, plasma exchange), and long-term immunomodulatory procedures (thymectomy).

Few major unmet needs in the market include therapeutic and diagnostic challenges, economic and humanistic burden, role of thymus and thymectomy warrants further research, and incidence of meningococcal infection in people treated with Soliris (eculizumab).

Recent Developments In The Generalized Myasthenia Gravis Treatment Landscape

• In April 2025, Johnson & Johnson (NYSE: JNJ) announced that the FDA has approved IMAAVY™ (nipocalimab-aahu), a human FcRn-blocking monoclonal antibody, for the treatment of generalized myasthenia gravis (gMG). This approval, granted after FDA Priority Review, provides a new treatment option for both adults and pediatric patients (12 years and older) who are anti-acetylcholine receptor (AChR) or anti-muscle-specific kinase (MuSK) antibody positive.
• In April 2025, argenx announced FDA approval of a prefilled syringe option for self-injection of VYVGART® Hytrulo (efgartigimod alfa and hyaluronidase-qvfc) to treat adults with generalized myasthenia gravis (gMG) who are AChR antibody positive and those with chronic inflammatory demyelinating polyneuropathy (CIDP).
• In March 2025, the FDA granted approval for an expanded indication of eculizumab (Soliris; Alexion/AstraZeneca) to include both adult and pediatric patients aged 6 years and older with generalized myasthenia gravis (gMG) who are antiacetylcholine receptor (AChR) antibody positive.

Generalized Myasthenia Gravis Emerging Drugs

• Rozanolixizumab: UCB Biopharma

Rozanolixizumab is a subcutaneously administered, humanized monoclonal antibody that specifically binds, with high affinity, to the human neonatal Fc receptor (FcRn). It has been designed to block the interaction of FcRn and Immunoglobulin G (IgG), accelerating antibodies' catabolism and reducing pathogenic IgG autoantibodies' concentration. Rozanolixizumab is under clinical development to improve the lives of people with pathogenic IgG-autoantibody-driven autoimmune diseases, including gMG, primary immune thrombocytopenia (ITP), myelin oligodendrocyte glycoprotein antibody-associated disease (MOG-AD) and autoimmune encephalitis (AIE) by driving removal of pathogenic IgG autoantibodies.

The drug is currently being evaluated in Phase III of its clinical trials for the treatment of generalized myasthenia gravis.

• Subcutaneous Efgartigimod: Argenx-Halozyme Therapeutics

Subcutaeous Efgartigimod is a novel formulation of the drug VYVGART (efgartigimod alfa-fcab). VYVGART is the first and only approved FcRn blocker. It is a human IgG1 antibody fragment that binds to the neonatal Fc receptor (FcRn), resulting in the reduction of circulating immunoglobulin G (IgG) autoantibodies Subcutaneous Efgartigimod is co-formulated with recombinant human hyaluronidase PH20 (rHuPH20). Halozyme's ENHANZE drug delivery technology allows for subcutaneous delivery of biologics that are typically administered via infusion. This new formulation aims to provide subcutaneous administration options for patients based on individual preferences. SC Efgratigimod completed its Phase III clinical trials and positive results of pivotal studies were released in March 2022.

Generalized Myasthenia Gravis Market Reimbursement Scenario

Proactively approaching reimbursement can induce a positive impact both during the early stages of product development and well after product launch. The Generalized Myasthenia Gravis Market Research Report considers reimbursement to identify economically attractive indications and market opportunities. When working with finite resources, the ability to select the markets with better market access can be a critical business and price strategy.

Medical treatment is based on cholinesterase inhibitors, corticosteroids, and immunosuppressants. Long-term maintenance therapy poses some caveats. Many patients need high doses of prednisone to do well, but the potential side effects of corticosteroids make the clinicians substitute prednisone for immunosuppressive drugs, including azathioprine, cyclosporine, tacrolimus, mycophenolate, and Rituximab. Plasma exchange/Plasmapheresis (PE/PP) is also effective against anti-AChR antibody-negative MG.

The My VYVGART Path by Argnex offers multiple resources to patients, including insurance and reimbursement support. Similarly, Alexion OneSource CoPay Program helps patients have commercial or private insurance and unapproved prescription coverage. The program pays for eligible out-of-pocket medication and infusion costs associated with Soliris (eculizumab) up to USD 15,000 US dollars per calendar year.

In an economic evaluation, the mean per-patient annual direct medical cost of illness was estimated at between USD 760 in Japan and USD 28,780 in the US, and the cost per hospitalization between USD 2,550 and USD 164,730. The indirect cost of illness was estimated at USD 80 and USD 3,550.
