Current Treatments and Emerging Therapies for Myasthenia Gravis

Myasthenia Gravis (MG) is a chronic autoimmune neuromuscular disorder that causes weakness and rapid fatigue in voluntary muscles. The condition is primarily driven by antibodies that block or destroy the communication between nerves and muscles, making even simple movements difficult for patients.

While traditional treatments have improved patient outcomes for decades, rapid advances in immunology and biotechnology are now ushering in a new era of targeted therapies. Yet, challenges in diagnosis, access to care, and disease variability continue to complicate management.

This blog explores the latest advancements, ongoing challenges, and what lies ahead for Myasthenia Gravis care.

Current Treatments and Emerging Therapies for Myasthenia Gravis

Recent years have seen the introduction of precision therapies targeting specific disease mechanisms:

1. Complement Inhibitors

• Eculizumab (Soliris) and Ravulizumab (Ultomiris) block the complement cascade to protect the neuromuscular junction

• Pros: Highly effective in treatment-resistant cases

• Cons: Very high cost; increased risk of meningococcal infection

  
  

2. Neonatal Fc Receptor (FcRn) Inhibitors

• Efgartigimod (Vyvgart) and Rozanolixizumab (Rystiggo) reduce pathogenic IgG antibodies by blocking their recycling

• Pros: Rapid onset, favourable safety profile

• Cons: Requires repeated infusions; long-term data still developing

  
  

3. B-cell Targeted Therapy

• Rituximab (off-label) is particularly effective in MuSK-positive MG by depleting antibody-producing B cells

  
  

4. Subcutaneous Immunoglobulin (SCIg)

• A home-based alternative to IVIg with comparable efficacy, improving convenience and autonomy for patients

  
  

5. Gene and Cell Therapies (Experimental)

• Early-stage research is exploring approaches to address the autoimmune process at its root

Ongoing Challenges in MG Management

Despite therapeutic progress, several hurdles remain:

1. Delayed or Missed Diagnosis – MG can mimic other neurological disorders. In resource-limited settings, lack of access to antibody testing or electrodiagnostic delays treatment initiation.

2. Disease Heterogeneity – Variations in antibody subtype, age of onset, and symptom severity mean a single treatment approach rarely works for all.

3. Limited Access to Advanced Therapies – High costs of biologics such as complement and FcRn inhibitors restrict access, particularly in low-income regions.

4. Long-Term Safety Concerns – The prolonged use of novel immunotherapies raises questions about infection risk, malignancies, and overall immune suppression.

5. Unpredictable Disease Course – Even under treatment, patients may experience relapses or crises requiring urgent intervention.

Conclusion

Myasthenia Gravis care is moving beyond steroids and broad-spectrum immunosuppressants toward highly targeted therapies. The future holds promise for safer, more effective, and more personalized treatment strategies. However, barriers around affordability, early detection, and equitable access must be addressed to translate these innovations into widespread benefit.

A collaborative, patient-centered approach, uniting healthcare providers, researchers, policy makers, and advocacy groups will be essential to truly transform MG management.
