Altered levels of immune proteins associated with the complement system may be implicated in generalized myasthenia gravis (MG), a new study suggests. The study, “Changes in serum complements and their regulators in generalised myasthenia gravis,” was published in the European Journal of Neurology. The complement…

A patient with three different types of myasthenia gravis (MG)-associated antibodies was described in a recent case report. The report, “Anti-MuSK positive myasthenia gravis with anti-Lrp4 and anti-titin antibodies,” was published in Internal Medicine. MG is caused by the immune system attacking the…

Treatment with IMVT-1401 significantly eased symptoms and lowered antibody levels in adults with moderate-to-severe generalized myasthenia gravis (MG), top-line results of a small Phase 2a trial show. Use of this investigative antibody at two doses was also seen to be safe and well tolerated. Results are expected to…

Measuring levels of a protein known as suPAR in the blood could be useful for assessing the severity of myasthenia gravis (MG), a pilot study reports. The study, “Serum level of soluble urokinase plasminogen activator receptor (suPAR) as a disease severity marker of myasthenia gravis: a…

Argenx is planning to submit an application to the U.S. Food and Drug Administration (FDA) by the end of this year for its lead candidate, efgartigimod (ARGX-113), for the treatment of generalized myasthenia gravis (gMG), the company announced. Assuming the biologics license application (BLA)…

A 60-year-old man being treated for multiple myeloma was found to have myasthenia gravis (MG) caused by antibodies against muscle-specific tyrosine kinase (MuSK), a study reports. This unusual case indicates that cancer treatments may mask the symptoms of MG, complicating diagnosis, researchers said. The case was described…

Achieving minimal disease symptoms six months after thymectomy predicts favorable long-term outcomes in people with myasthenia gravis (MG), a study suggests. The research also found that shortness of breath prior to surgery is associated with worse treatment outcomes. The study, “Prognostic Analysis of Thymoma-Associated Myasthenia Gravis (MG) in…

Treatment with rituximab is safe, provides clinical improvements and enables stopping maintenance therapies in patients with late-onset myasthenia gravis (LOMG), a small study suggests. The study, “Rituximab in Late‐Onset Myasthenia Gravis is Safe and Effective,” was published in the journal Muscle & Nerve. Rituximab —…

New guidelines have been published to help patients and physicians manage myasthenia gravis (MG) and Lambert-Eaton myasthenic syndrome (LEMS) during the COVID-19 pandemic. Broadly, the guidelines suggest that people with MG or LEMS should continue on their current therapies and take extra precautions to minimize the chance…

Out-of-pocket expenses for people in China who have myasthenia gravis  increased from 2013 to 2015, suggesting that current policies for medical insurance in China are inadequate for those living with the disease, a new study has found. The study, “Out-of-pocket expenses for myasthenia gravis patients in China:…
