A Study of the Anti-CD 19 Chimeric Antigen Receptor T Cell Therapy for Patients with Myasthenia Gravis
Myasthenia gravis (MG) is a chronic autoimmune disease that affects the neuromuscular junction and is characterized by muscle weakness. B cells play a role in MG, and the disease is characterized by the presence of autoantibodies such as anti-AChR and anti-MuSK antibodies. CD-19 target chimeric antigen receptor (CAR) T cells harness the ability of cytotoxic T cells to directly and specifically lyse target cells to effectively deplete both normal and autoreactive B cells in the circulation as well as impacted lymphoid and potentially non-lymphoid tissues. KYV-101 (mivocabtagene autoleucel \[miv…
