Myasthenia Gravis Treatment Market - Global Forecast 2025-2030

The Myasthenia Gravis Treatment Market size was estimated at USD 2.00 billion in 2024 and expected to reach USD 2.11 billion in 2025, at a CAGR 5.48% to reach USD 2.76 billion by 2030.

Myasthenia gravis is a chronic autoimmune neuromuscular disease marked by fluctuating muscle weakness that intensifies with activity and improves with rest, reflecting an attack by autoantibodies on components of the neuromuscular junction. Voluntary muscles responsible for ocular movements, facial expressions, chewing, and breathing bear the brunt of impaired signal transmission, leading to symptoms such as ptosis, diplopia, dysphagia, and respiratory compromise when severe.

The epidemiology of myasthenia gravis underscores its rare but impactful nature, with an overall incidence of approximately 3.2 per 100,000 individuals and a prevalence hovering around 37 per 100,000 in the United States as of 2021. Incidence and prevalence both rise sharply with age, peaking at over 10 new cases per 100,000 person-years and more than 116 cases per 100,000 in those aged 65 and older. These updated figures reflect improved diagnostic awareness and an aging population burdened by chronic autoimmune conditions.

Conventional symptomatic therapy with acetylcholinesterase inhibitors and broad immunosuppressants such as corticosteroids, azathioprine, cyclosporine, and mycophenolate mofetil has long formed the backbone of treatment. However, real-world data reveal that up to 30 percent of patients fail to achieve sustained disease control, and many experience adverse effects that limit long-term tolerability. Emerging evidence from Phase 3 trials of targeted biologics highlights an unmet need for therapies offering rapid onset, durable efficacy, and improved safety profiles.

Against this backdrop of persistent unmet need and evolving scientific understanding of immunopathogenesis, innovative modalities are reshaping clinical practice. A thorough grasp of the current landscape-spanning epidemiology, pathophysiology, and patient-centric gaps-establishes the foundation for evaluating transformative therapies and strategic market opportunities in myasthenia gravis care.

Recent years have witnessed a paradigm shift in myasthenia gravis management, driven by targeted therapies that transcend symptomatic relief. The introduction of neonatal Fc receptor (FcRn) inhibitors such as efgartigimod in December 2021 marked the first approval of a novel mechanism designed to reduce pathogenic IgG autoantibodies at their source, demonstrating responder rates exceeding 68 percent versus 30 percent for placebo and heralding a new class of immunomodulators. Building on this momentum, the FDA cleared a prefilled syringe formulation of efgartigimod with enhanced patient convenience and home administration capabilities in April 2025, underscoring the trend toward patient-centered delivery options.

Complement inhibition has further redefined treatment expectations. Eculizumab’s ground-breaking approval in October 2017 laid the groundwork for ravulizumab’s emergence as a long-acting C5 inhibitor, approved in April 2022 following the CHAMPION-MG trial that demonstrated sustained improvements in the MG-ADL score at 26 weeks (–3.1 vs. –1.4; P <.001). The extended dosing interval of ravulizumab has alleviated treatment burden and enabled broader patient adoption across antibody-positive generalized myasthenia gravis.

Neonatal Fc receptor blockers have since expanded, with rozanolixizumab securing FDA approval under Priority Review in June 2023 as the first subcutaneous agent targeting both anti-AChR and anti-MuSK antibody-positive patients, thereby addressing a key heterogeneity in disease subtype and empowering individualized regimens. The most recent innovation arrived in April 2025 with the approval of nipocalimab, a high-affinity FcRn-blocking monoclonal antibody that achieved up to 75 percent sustained IgG reduction and durable MG-ADL improvements in the Vivacity-MG3 study, now available for adults and pediatric patients aged 12 and older.

Alongside biologic advances, digital health solutions are gaining traction, integrating remote neuromuscular monitoring and telemedicine platforms into clinical workflows to optimize dosing schedules and bolster adherence. This confluence of precision biologics and technology-enabled care pathways signifies a truly transformative era in myasthenia gravis treatment, characterized by a shift from empirical management to mechanism-driven, patient-centric approaches.

The implementation of broad 2025 trade measures introduced a uniform 10 percent tariff on nearly all goods entering the United States, encompassing key healthcare inputs such as active pharmaceutical ingredients (APIs), finished pharmaceutical products, and medical devices. Certain jurisdictions have faced escalated duties, including up to 245 percent on Chinese-sourced APIs and 25 percent on devices from Canada and Mexico, as part of a strategic push toward onshoring critical manufacturing capabilities under national security mandates.

Independent analysis has revealed the economic burden of such tariffs: a 25 percent levy on finished pharmaceutical imports could elevate U.S. drug costs by roughly $51 billion annually and drive consumer prices upward by as much as 12.9 percent if fully passed along the supply chain. Concurrently, tariffs on APIs used in domestic production threaten to inflate manufacturing costs by over 4 percent, disproportionately impacting generics that operate on thin margins and rely heavily on imported inputs.

These cost pressures carry tangible risks for patient access and supply chain resilience. With China accounting for approximately 40 percent of APIs in U.S. generics, heightened tariffs may compel manufacturers to curtail production or exit the market, setting the stage for acute drug shortages and exacerbating vulnerabilities in the hospital and home care settings that depend on injectable generics. Parallel tariffs on medical devices further strain hospital budgets, potentially hindering the adoption of emerging neuromuscular monitoring technologies.

In response, industry leaders are expediting reshoring initiatives, forging alternative supplier alliances, and advocating for targeted exemptions to shield critical therapies. While these measures promise long-term supply security and potential cost offset through domestic API manufacturing, they entail significant capital outlays and extended timelines, underscoring the urgency of proactive policy engagement to mitigate short-term disruptions.

A multifaceted segmentation framework reveals the nuanced drivers and access patterns shaping patient journeys in myasthenia gravis care. Treatment class distinctions span from foundational acetylcholinesterase inhibitors to broader immunosuppressants-corticosteroids and a spectrum of nonsteroidal agents including azathioprine, cyclosporine, and mycophenolate mofetil-alongside advanced modalities such as intravenous immunoglobulin, monoclonal antibodies like eculizumab, ravulizumab and rituximab, and plasma exchange. Delving further, immunosuppressant strategies bifurcate into corticosteroids for rapid symptom control and nonsteroidal alternatives for long-term disease modulation, while monoclonal antibodies carve out targeted complement and FcRn blockade niches.

Administration route segmentation underscores patient and provider preferences across intravenous regimens facilitating rapid therapeutic exposure, oral formulations offering convenience for chronic maintenance, and subcutaneous options that empower home-based self-administration. Distribution channel analysis highlights the evolving role of hospital pharmacies in acute settings, the burgeoning footprint of online pharmacies enhancing patient convenience, and the enduring relevance of retail pharmacies in community-based chronic care.

End-user differentiation further contextualizes care delivery, with specialized neuromuscular clinics providing multidisciplinary evaluation and infusion services, home care platforms extending maintenance therapies into patients’ residences, and hospitals managing crises and high-acuity interventions. These dimensions collectively illustrate the heterogeneity of clinical practice, reimbursement pathways, and patient engagement models that must be aligned to optimize treatment adoption and outcomes in myasthenia gravis.
