Measuring how much immunoglobulin G (IgG) antibody levels drop after plasmapheresis, a blood-cleansing treatment for myasthenia gravis (MG), may help in determining the disease’s likely course, at least in the short term, a small study suggests. Changes in this potential biomarker that signal improvement also could help in…
Daily treatment with zilucoplan was tied to meaningful reductions in symptom severity among the subgroup of Japanese generalized myasthenia gravis (gMG) patients who participated in the Phase 3 RAISE clinical trial, according to new subgroup analyses. The data add to accumulating trial evidence that the UCB therapy…
About two years treatment with the immunosuppressant tacrolimus safely and effectively eases symptoms in children and adolescents with myasthenia gravis (MG) while cutting down the need for oral prednisone, according to a small study in China. Corticosteroids like prednisone, often used when other medications fail to control…
A treatment based on GRO Biosciences‘ ProGly program — which uses specially designed proteins to regulate the immune system — substantially reduced disease activity in an animal model of myasthenia gravis (MG), according to new data presented by the company. “We are greatly encouraged by the results of…
UCB’s zilucoplan and Rystiggo (rozanolixizumab) both were approved in Japan to treat adults with generalized myasthenia gravis (gMG) who lack an adequate response to steroids or other immunosuppressive treatments. “With the approval in Japan of zilucoplan and [Rystiggo], we are very proud and excited to expand our…
Health Canada has approved Vyvgart (efgartigimod alfa-fcab) to treat adults with generalized myasthenia gravis (gMG) who are positive for antibodies targeting the acetylcholine receptor (AChR), the most common target of MG-causing antibodies. The approval is based on positive data from the Phase 3 ADAPT clinical trial (NCT03669588),…
A more severe disease course was seen among pediatric myasthenia gravis (MG) patients with antibodies against acetylcholine receptors (AChRs) who also have antibodies against ryanodine receptors (RyR) and the titin protein, according to a new study. These children had a higher likelihood of having generalized MG (gMG) and…
A 44-year-old woman positive for the human immunodeficiency virus (HIV) developed myasthenia gravis (MG) after receiving treatment with antiretroviral agents. While no clear guidelines exist for treating MG in HIV-infected patients, researchers noted the woman was successfully treated with prednisone, azathioprine, and plasma exchange. According to them, this approach…
A European Medicines Agency (EMA) committee has recommended the approval of Argenx’s under-the-skin, or subcutaneous, formulation of efgartigimod as an add-on to standard therapy for adults with generalized myasthenia gravis (gMG) who have antibodies against acetylcholine receptors (AChRs). Argenx’s into-the-vein (intravenous) formulation of efgartigimod, sold as Vyvgart,…
Treatment with the experimental therapy povetacicept (ALPN-303) reduced disease activity in a mouse model of myasthenia gravis (MG), according to data shared by its developer, Alpine Immune Sciences. Povetacicept also was tolerated well by healthy volunteers participating in a Phase 1 clinical trial. “Together, these data provide strong…
