A Phase 1/2, Open-Label Study to Evaluate the Safety and Efficacy of Autologous CD19-specific Chimeric Antigen Receptor T Cells (CABA-201) in Subjects With Active Idiopathic Inflammatory Myopathy or Juvenile Idiopathic Inflammatory Myopathy

Idiopathic inflammatory myopathies (IIMs, or myositis) are a group of rare autoimmune diseases characterized by inflammation and muscle weakness. Though the cause of IIM is not well understood, some subtypes of IIM, including dermatomyositis (DM), anti-synthetase syndrome (ASyS), immune-mediated necrotizing myopathy (IMNM), and juvenile idiopathic inflammatory myopathy (JIIM), are thought to involve B cells that cause the body to attack different tissues in the body. This study is being conducted to evaluate the safety and efficacy of an investigational cell therapy, CABA-201, that can be give…
