A Phase 1 clinical trial for IGM-2644, a potential first-in-class immune T-cell engager therapy for generalized myasthenia gravis (gMG), should begin by the end of the year, said its developer IGM Biosciences. “Our early pivot to using T-cell engagers in autoimmune disease has enabled significant progress on these…
The case of a 72-year-old man who developed myasthenia gravis (MG) and myocarditis, or inflammation of the heart, following chemoimmunotherapy for gastric cancer that included sintilimab showcases the need to better understand how this treatment can induce the immune disorder, said researchers in China. Sintilimab is a type of…
Vyvgart Hytrulo (efgartigimod alfa and hyaluronidase), an approved therapy for generalized myasthenia gravis (gMG) that’s injected under the skin, or subcutaneously, appears to be as effective as the intravenous treatment Vyvgart (efgartigimod alfa) at reducing IgG antibodies, including those that cause the disease. That’s according to data…
Amgen’s antibody-based therapy inebilizumab reduces the severity of generalized myasthenia gravis (MG), according to top-line data from a Phase 3 clinical trial. Dubbed MINT (NCT04524273), the study showed inebilizumab’s therapeutic efficacy in gMG patients who test positive for self-reactive antibodies against the acetylcholine receptor (AChR) or muscle-specific…
ARGX-119, an antibody designed to increase the activity of the muscle-specific kinase (MuSK) protein, protected against the development of neuromuscular disease in mice in a model of MuSK-associated myasthenia gravis (MG), and eased or reversed evident symptoms in animals with disease onset, scientists report. With further work, such an…
Blood levels of specific antibodies that target the muscle-specific tyrosine kinase (MuSK) may be biomarkers of disease severity and treatment response in people with myasthenia gravis (MG) who are positive for anti-MuSK antibodies. A study finds that high levels of MuSK-IgG4 — an anti-MuSK antibody subclass – were associated…
Treatment with the immunosuppressant Prograf (tacrolimus) within one year of the onset of juvenile myasthenia gravis (JMG) was found to be safe and effective in a study of pediatric patients in China. Patients who were started on Prograf earlier after JMG onset were significantly more likely to achieve…
The use of myasthenia gravis (MG) treatments did not increase COVID-19 infection risk or severity, according to a new study of Chinese patients with both generalized myasthenia gravis (gMG) and ocular types of MG. In fact, continuing treatment with nonspecific nonsteroidal immunosuppressants and antibody therapies during infection…
Johnson & Johnson has submitted an application to the European Medicines Agency (EMA) seeking approval of nipocalimab to treat people with generalized myasthenia gravis (gMG). The request includes gMG patients who are positive for MG-causing autoantibodies targeting acetylcholine receptors (AChRs), muscle-specific tyrosine (MuSK), and low-density lipoprotein…
Both Soliris (eculizumab) and Vyvgart (efgartigimod alfa-fcab) rapidly eased disease severity among adults with generalized myasthenia gravis (gMG), according to a real-world study that compared the two therapies. Soliris outperformed Vyvgart in its ability to reduce gMG severity and corticosteroid dose over a year of treatment, however.
