SC291-102 is a Phase 1 study examining the safety and effects of a new treatment called SC291 for people with severe autoimmune diseases. Autoimmune diseases make the body's immune system attack itself, and this study focuses on conditions like systemic lupus erythematosus (SLE) and anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). SLE can damage organs, and AAV affects blood vessels. In this study, patients will receive one dose of SC291 after being prepared with medicines called cyclophosphamide (CY) and fludarabine (FLU). The treatment aims to help those who have not improved with other therapies. Participants in the study should be between 18 and 75 years of age and must not have had similar cell therapies before.
- Study involves receiving a single dose of the investigational treatment.
- Participants must have tried at least two other treatments without success.
- People with certain brain or nerve issues cannot participate.
