CD19 CAR T Arm · שלב 2
על הניסוי
The goal of this clinical trial is to evaluate whether anti-CD19 CAR T-cell therapy can improve disease activity in adults with severe, treatment-resistant systemic sclerosis (SSc). The study will also assess the safety of this therapy and how CAR T-cells behave in the body. The main questions are: Does CAR T-cell therapy reduce skin thickening and other signs of SSc? What side effects occur after receiving CAR T-cells? How do CAR T-cells expand, persist, and affect B-cells and autoantibodies? Participants will: Undergo leukapheresis Receive short lymphodepleting chemotherapy Receive one infusion of anti-CD19 CAR T-cells Stay in the hospital for about 10 days Attend follow-up visits for 24 months with clinical exams, blood tests, and organ-function assessments Optional skin or lymph-node biopsies may be performed in participants who consent to these procedures. This study aims to provide early evidence on whether CAR T-cell therapy could become a promising treatment option for systemic sclerosis.
