"Myasthenia Gravis in 2025: Breakthroughs on the Horizon and a Champion’s New Mission"

Introduction – A Turning Point in MG Awareness and Treatment 

Myasthenia Gravis (MG) is a rare but potentially debilitating autoimmune neuromuscular disorder that disrupts communication between nerves and muscles, causing fluctuating muscle weakness that worsens with activity and improves with rest HealthMedscapeCleveland Clinic. While the condition has long presented challenges in both diagnosis and long-term management, 2025 marks a pivotal year: new biologic therapies are being approved, offering targeted approaches that bring renewed hope to patients and providers alike JCINature.

At the same time, a powerful voice has emerged to raise public awareness: nine-time Grand Slam tennis champion Monica Seles has recently shared her personal battle with MG, transforming her athletic legacy into an advocacy platform for others navigating this condition ReutersAP News.

This article explores both the scientific advances redefining treatment horizons and the human stories shaping awareness, providing readers with a holistic view of where MG stands today—and where it might be headed.

1. Understanding Myasthenia Gravis — Then and Now

MG arises when the immune system mistakenly produces antibodies—most commonly against the acetylcholine receptor (AChR), but also muscle-specific kinase (MuSK) or LRP4—that impair signal transmission at the neuromuscular junction (NMJ), leading to muscle fatigue and weakness Myasthenia Gravis Foundation of AmericaMedscapeCleveland Clinic.

Patients typically experience symptoms affecting ocular muscles first—such as drooping eyelids (ptosis) or double vision (diplopia)—and may later develop weakness in facial, throat, limb, or respiratory muscles Mayo ClinicJohns Hopkins MedicineCleveland Clinic. The weakness is often variable, fluctuating over time and worsening with exertion HealthNCBI.

Despite its severity, MG is no longer the dire prognosis it once was. In the early 20th century, as many as 70% of diagnosed patients died from lung complications. Today, vigilant treatment and monitoring mean fatality rates have dropped to around 3%–5% Wikipedia.

Diagnosis often involves clinical assessments, blood tests for autoantibodies, electrophysiological studies such as single-fiber EMG, and imaging to evaluate the thymus gland Cleveland ClinicMyasthenia Gravis Foundation of AmericaMayo Clinic. Treatments include symptom management with acetylcholinesterase inhibitors, immunosuppressive therapies, plasmapheresis or IVIG for crises, and thymectomy—especially if a thymoma is present HealthWikipedia+1.

2. Revolution in Treatment: Approved Biologic Therapies in 2025 

2.1 FcRn Inhibitors

– Efgartigimod alfa (Vyvgart), approved in the U.S. in December 2021 and co-formulated with hyaluronidase (Vyvgart Hytrulo) in June 2023, targets the neonatal Fc receptor (FcRn) to reduce IgG antibody levels, including pathogenic AChR antibodies Wikipedia+1.

– Rozanolixizumab (Rystiggo), another FcRn blocker, was approved in the U.S. in June 2023 and in the EU in January 2024 Wikipedia.

– Nipocalimab (Imaavy), a high-affinity, fully human monoclonal antibody FcRn blocker, was approved in the U.S. in April 2025. Data from its open-label extension (OLE) and indirect treatment comparisons (ITC) show that it delivers sustained disease control, with symptom relief noticeable from week one and consistent improvements through 24 weeks—outperforming other FcRn inhibitors in some measures WikipediaInnovative Medicine GlobalJohnson & Johnson Investor Relations.

2.2 Complement Inhibition

– Zilucoplan (Zilbrysq), a subcutaneous cyclic peptide that inhibits complement component C5, received U.S. approval in October 2023, EU in December 2023, and Australia in July 2024 Wikipedia.

2.3 B-Cell Depletion and Other Emerging Options

A 52-week trial known as MINT, focusing on inebilizumab (B-cell depletion therapy), recently revealed promising, durable symptom relief in Acetylcholine Receptor-positive generalized MG (gMG), suggesting a potential new standard of care AmgenNew England Journal of Medicine.

Moreover, a comprehensive review in BioDrugs (March 2025) summarizes these advances and others still in late-stage development—offering clinicians a clearer roadmap for tailored treatment decisions PubMedSpringerLink.

Additionally, the 2025 “Five New Things and Four Hopes” framework—published in J Neurol—highlights key advances including new immunotherapies, biomarkers, treatment stratified by MG “age” and “stage”, and potential future strategies like CAR T-cell therapy ean.orgPMC.

2.4 Looking Ahead: Personalized and Stratified Care

Experts point to progress in biomarker development (e.g., live cell-based assays), the need for age-specific treatment strategies, and hopes for innovative approaches like CAR T-cell therapy—though challenges remain concerning cost and safety ean.org.

3. Surgical Approaches and Treatment Strategy Evolution

Thymectomy, or removal of the thymus gland, remains an important option, especially when thymoma is present. It may also benefit select patients without thymoma, yielding remission with the aid of medication—even if not always permanent Wikipedia+1.

Modern surgical techniques—such as transcervical and video-assisted thoracoscopic approaches—offer less invasive options with comparable outcomes to traditional transsternal surgery Wikipedia.

On the horizon is a shift from broad immunosuppression toward precision, antibody- or pathway-targeted therapies, declining reliance on steroids and broad immunosuppressants. This aligns with a growing interest in protecting the NMJ early and stratifying treatment based on age, comorbidities, and autoantibody profile ean.orgJCINature.

4. The Human Face: Monica Seles Amplifies MG Awareness 

In a profound move, Monica Seles, the 51-year-old tennis legend and nine-time Grand Slam champion, went public with her decade-plus battle with MG—raising awareness not just in the medical community, but across millions of sports fans ReutersAP News.

While she first noticed symptoms such as double vision and weakness four to five years ago, the diagnosis of MG came three years ago ReutersThe Sun. Seles describes the condition as a “difficult one” that significantly complicates daily tasks—from brushing her hair to performing simple actions People.com.

Her openness is deeply personal: she compares accepting MG with past “resets” in her life—immigrating to the U.S., overcoming early fame, surviving a life-threatening on-court stabbing in 1993, and re-emerging post-retirement AP NewsPeople.com.

Now, partnering with argenx for the “Go for Greater” campaign, Seles aims to share resources, support others with MG, and foster community understanding ahead of the U.S. Open AP NewsReuters.

Her advocacy underscores an essential truth: MG is not just a medical condition—it’s a lived, daily challenge. Public figures like Seles can turn clinical complexity into empathetic understanding, inspiring both patients and clinicians to push for better outcomes.

5. What It Means for Patients and Clinicians
