What this Trial Is About

The CATARSIS study explores the use of anti-CD19 CAR T-cell therapy as a novel approach for treating refractory systemic autoimmune diseases, specifically SLE, SSc, DM/PM, and AAV. These life-threatening conditions often resist current therapies, and B cells play a key role in their pathogenesis. The study employs CD19-CAR\_Lenti, an autologous CAR T-cell product targeting CD19-positive B cells, aiming to reduce inflammation and autoimmunity. This open-label, single-dose, phase I basket trial will assess the safety, feasibility, and preliminary efficacy of CAR T-cell therapy, focusing on adverse events, infection rates, and overall response at 24 weeks. Eight participants will be included.
