Brief Summary:
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.
Detailed Description:
Systemic sclerosis (SSc) is a rare and severe autoimmune disease characterized by fibrosis of the skin and multiple organs, vasculopathy, and immune dysregulation. Many patients continue to experience active and progressive disease despite conventional immunosuppressive treatments, including disease modifying antirheumatic drugs (DMARDs) and biologics. Therapeutic options remain limited, and there is a significant unmet medical need for innovative approaches targeting the underlying mechanisms of the disease.
Recent preliminary experience from studies conducted in autoimmune diseases-such as lupus, myositis, and systemic sclerosis-suggests that autologous anti CD19 CAR T cell therapy may help reduce disease activity. Reported observations include transient B cell depletion, decreases in autoantibody levels, and improvements in joint, pulmonary, and cardiac manifestations. These early results support further evaluation of CAR T cell therapy in systemic sclerosis in a structured clinical trial setting.
This Phase IIa, multicenter, single-arm study is designed to evaluate the feasibility and safety of autologous anti-CD19 CAR-T cell therapy in adults with active systemic sclerosis who are resistant to immunosuppressive treatments. The study also aims to generate early clinical and biological data to assess the potential value of this therapeutic strategy in this population.
Eligible participants will undergo leukapheresis for T-cell collection. Following standard manufacturing of autologous anti-CD19 CAR-T cells in a GMP (Good Manufacturing Practice)-certified facility, participants will receive a short course of lymphodepleting chemotherapy, followed by a single intravenous infusion of CAR-T cells. They will remain hospitalized for intensive monitoring during the early post-infusion period, in accordance with established procedures for CAR-T cell therapies. Participants with known hypersensitivity to drugs required for treatment-related toxicity are excluded, as specified in the protocol.
After discharge from the hospital, participants will have follow-up visits for up to 24 months. These visits will include clinical and biological assessments as well as appropriate imaging tests to monitor disease activity, treatment safety, and overall health status. Biological samples will also be collected at specific times for centralized analysis.
The study incorporates exploratory immunological and translational research components. These may include monitoring circulating CAR T cells, characterizing immune cell subsets, and evaluating selected biomarkers. Optional skin and lymph node biopsies may be performed in consenting participants to analyze immune cell phenotypes and tissue level changes associated with treatment. Additional exploratory analyses may assess the spatial organization and distribution of immune cells within tissue samples, as described in the study protocol.
Overall, the study aims to provide early data on the use of anti CD19 CAR T cell therapy in systemic sclerosis, including feasibility, safety, and biological signals of activity. The results are expected to contribute to the development of innovative cell based therapeutic strategies for this severe autoimmune disease.
