No

Inclusion Criteria

  • Age ≥18 and ≤70 years of age - Diagnosis of MG with generalized muscle weakness meeting criteria as defined by the MGFA class II, III , IVa, and IVb. - Diagnosis of seropositive (autoantibodies AChR, MuSK and/or LRP4) or seronegative MG

Exclusion Criteria

  • Contraindication to leukapheresis - History of anaphylactic or severe systemic reaction to fludarabine, cyclophosphamide or any of their metabolites - Active infection requiring medical intervention at screening - Current symptoms of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, pulmonary, psychiatric, cardiac, neurological, or cerebral disease, including severe and uncontrolled infections, such as sepsis and opportunistic infections. - Concomitant medical conditions that, in the opinion of the investigator, might place the subject at unacceptable risk for participation in this study, interfere with the assessment of the effects or safety of the investigational product or with the study procedures - Significant lung or cardiac impairment - Prior solid organ (heart, liver, kidney, lung) transplant or hematopoietic cell transplant Other protocol-defined inclusion/exclusion criteria may apply.

Detailed Description

Myasthenia gravis (MG) is a rare autoimmune disorder characterized by autoantibody responses that cause defective transmission of signals at the neuromuscular junction, resulting in a distinctive pattern of weakness. Patients with generalized MG (gMG) typically experience symptoms associated with ocular disease in addition to weakness of many other voluntary muscle groups, including extremity, bulbar, and respiratory muscles. MG is considered a classic example of a B-cell mediated autoimmune disease. Currently, there are no curative treatments for MG. 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 gMG. A single dose of CABA-201 in combination with cyclophosphamide (CY) and fludarabine (FLU) will be evaluated.
