The European Commission has approved Vyvgart (efgartigimod) as an add-on to standard treatment for adults with generalized myasthenia gravis (gMG) who are positive for antibodies against acetylcholine receptor (AChR), the most common type of MG-driving antibody. “We share the excitement with the European gMG community in bringing a…

A combination of glucocorticoids and intravenous immunoglobulin (IVIG) is more effective at normalizing immune responses and easing disease symptoms in children with ocular myasthenia gravis (OMG) than glucocorticoids alone, a study showed. The combination also could allow for a shorter duration and lower dose of glucocorticoids, also known…

The long-acting complement inhibitor Ultomiris (ravulizumab-cwvz) has been approved by the U.S. Food and Drug Administration (FDA) to treat most adults with generalized myasthenia gravis (gMG). The approval specifically covers patients who are positive for antibodies against the acetylcholine receptor (AChR) — about 80% of gMG patients. “With the…

The European Commission is expected to propose a new governing framework for health data next month, called the European Health Data Space (EHDS), with the aim of connecting national health systems to facilitate secure and efficient transfer of data across systems in different European nations. The move is expected to…

Treatment with Ultomiris (ravulizumab-cwvz) eased symptoms of generalized myasthenia gravis (gMG) for more than a year, according to new data from the ongoing CHAMPION-MG extension study. Findings were shared at the 2022 American Academy of Neurology (AAN) Annual Meeting in an oral presentation, titled “Long-term Efficacy and Safety of…

Many people with myasthenia gravis (MG) caused by antibodies against MuSK initially present with eye-related symptoms, which soon affect other parts of the body, according to a new study. “The present study provides a better understanding of MuSK-MG disease and its clinical course,” its researchers wrote. The study, “…
