Inclusion Criteria
- Age ≥18 and ≤75 - A clinical diagnosis of IIM, based on the 2017 The European League Against Rheumatism/American College of Rheumatology classification criteria - Diagnosis of DM, ASyS, IMNM based on the presence of serum myositis-specific antibodies - Evidence of active disease, despite prior or current treatment with standard of care treatments, as defined by the presence of elevated creatine kinase (CK), DM rash, or active disease on muscle biopsy, magnetic resonance imaging (MRI), or electromyography - Presence of muscle weakness
Exclusion Criteria

Detailed Description
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), and immune-mediated necrotizing myopathy (IMNM), 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 given to patients with DM, ASyS, and IMNM who have active disease. A single dose of CABA-201 in combination with cyclophosphamide (CY) and fludarabine (FLU) will be evaluated.
