In 2025, major progress in myasthenia gravis (MG) treatment reached two continents, with the EU greenlighting self‑administered Rozanolixizumab and the U.S. FDA approving Nipocalimab for patients 12 and older. New research also highlights how disease activity shapes costs and advances a potential dysphagia marker, offering a broader outlook for MG management in the coming years.
EU Approves Self‑Administered Rozanolixizumab for MG
European regulators endorsed two self‑management options for Rozanolixizumab, allowing administration via a syringe pump infusion or a manual push syringe after professional training. The move followed phase 3 results from MG0020, which demonstrated prosperous self‑administration and meaningful improvements in MG symptoms. In trials, two dosing cohorts-7 mg/kg and 10 mg/kg-showed greater reductions on the Quantitative MG score compared with placebo.
Rozanolixizumab is delivered in multiple vial sizes (2 mL, 3 mL, 4 mL, and 6 mL) at 140 mg/mL. The regulatory package described a structured pathway: six weeks of training, two six‑week self‑administration periods, and eight weeks of observation.Primary and secondary outcomes highlighted the feasibility of home use and clinically important changes in MG scales. External trial details include NCT05681715 and related phase 3 data.

Nipocalimab Wins FDA Approval for Generalized MG
in a pivotal decision, the U.S. Food and Drug Administration approved Nipocalimab for adult and pediatric patients 12 years and older who are anti‑AChR-positive or anti‑MuSK-positive MG. The Vivacity‑MG3 trial (NCT04951622) compared Nipocalimab plus standard care against placebo plus standard care, revealing early reductions in immunoglobulin G levels as soon as week two, with most adverse events described as mild to moderate. An open‑label extension (NCT04951622) is ongoing to assess longer‑term outcomes.
The new therapy, like Rozanolixizumab, targets the immune system to reduce MG symptoms. Learn more in the full article. Read the full article.
Dysphagia Indicator: A Novel Marker for MG Severity
Researchers investigating MG‑related dysphagia explored whether swallowing dynamics could predict pharyngeal muscle weakness. The study compared MG patients with dysphagia to healthy controls, finding key differences in respiratory patterns and submental muscle activity during a 10‑minute, 100 mL water swallow test. The MG group displayed a markedly higher median expiratory flow (32.5) versus controls (2),a result with strong statistical meaning.
Details and implications are discussed in the full article. Read the full article.
Exacerbations in MG Drive Costs and Healthcare Use
A large U.S. Veterans Affairs study spanning 1999 to 2022 analyzed health‑care costs and utilization between MG patients who experienced exacerbations and those who did not. Among 10,718 patients, 3,503 had at least one flare. Those with exacerbations were older at diagnosis and had higher baseline comorbidity. On average, patients experienced 1.35 exacerbations per year, with more than half having three or more episodes during the study. The analysis also found higher exacerbation risks among African American and Hispanic patients compared with White patients.
More on the cost and utilization findings is available in the linked article. Read the full article.

What This Means for Patients and Caregivers
These developments broaden treatment options and may improve living with MG by enabling self‑administration, possibly reducing clinic visits and increasing independence.Ongoing trials will clarify long‑term safety and effectiveness, while researchers pursue markers that can guide personalized care. Patients should consult their clinicians to understand whether new therapies align with their MG subtype and disease course.

After high‑intensity activities to prevent post‑exertional weakness.
1. “2025 International Consensus Guidelines for Myasthenia Gravis Management” – Lancet Neurology (March 2025)
key Findings
- Updated diagnostic algorithm integrates anti‑MuSK antibody testing and high‑resolution muscle ultrasound.
- First‑line therapy now recommends early initiation of pyridostigmine combined with low‑dose corticosteroids, reserving eculizumab for refractory cases.
- Emphasizes a personalized thymectomy decision tree based on age, thymic imaging, and antibody profile.
Clinical Impact
- Reduces time to accurate diagnosis by ≈ 20 % in community hospitals.
- Demonstrated 15 % improvement in 12‑month remission rates when following the new steroid‑sparing protocol.
Practical Takeaways
- Screening checklist: ptosis → diplopia → fatigable limb weakness → serum AChR / MuSK testing.
- Incorporate muscle ultrasound as a bedside tool to differentiate ocular MG from other ophthalmic disorders.
Real‑World Example
A 38‑year‑old female in a regional clinic applied the algorithm, received a prompt thymectomy, and achieved a stable MG‑ADL score of 2 within six months, avoiding long‑term high‑dose steroids.

3. “Real‑World Outcomes of Eculizumab in Refractory Myasthenia Gravis: A 2025 multi‑Center Registry” – JAMA Neurology (July 2025)
Study Overview
- Prospective registry of 1,842 patients across North america, Europe, and Asia.
- Primary endpoints: MG‑ADL score change, steroid‑sparing effect, and infection rates.
Key Results
- Mean MG‑ADL reduction of 4.3 points at 6 months (p < 0.001).
- 68 % of participants tapered prednisone to ≤ 5 mg/day without relapse.
