Brief summary

This is an open, single-arm, clinical study to evaluate the efficacy and safety of chimeric antigen receptor T cell immunotherapy (CAR-T) targeting BCMA or CD19 or both sequentially in the treatment of Relapsed/ Refractory Autoimmune Disease such as Sjogren's Syndrome or Systemic Lupus Erythematosus and other Autoimmune Disease.

Detailed description

Chimeric antigen receptor (CAR)-modified T cells targeted against CD19 have demonstrated unprecedented successes in treating patients with hematopoietic and lymphoid malignancies. Besides CD19, many other molecules such as CD22, CD30,BCMA,CD123, etc. may have the potential to develop the corresponding CAR-T cells to treat patients whose tumors express those markers. In this study, investigators will evaluate the safety and efficacy of CAR-T targeting CD19/BCMA in patients with Autoimmune Disease. The primary goal is safety assessment including cytokine storm response and any other adverse effects. In addition, disease status after treatment will also be evaluated. The purpose of this clinical trial is to assess the feasibility, safety, and efficacy of multiple CAR T-cell therapy that combines CAR T cells against Autoimmune Disease B Cells with CAR T cells targeting BCMA or CD19 or both in patients with relapsed and refractory Autoimmune Disease. The study also aims to learn more about the function of CAR T cells and their persistence in Autoimmune Disease patients.

Interventions

BIOLOGICALBCMA/CD19 CAR-T cells

The intervention in this clinical trial involves a novel approach using BCMA/CD19 Chimeric Antigen Receptor T (CAR T) cells combined with chemotherapy. The goal is to assess safety and efficacy in patients with specific hematologic malignancies. Treatment Regimen: Patients in the trial will undergo the following regimen: Fludarabine Phosphate (Days -4 to -2): IV administration of fludarabine phosphate over 30 minutes on days -4 to -2. It's part of the preparatory regimen to enhance the body's response to CAR T-cell therapy. Cyclophosphamide (Day -2): IV cyclophosphamide over 60 minutes on day -2. BCMA/CD19 Chimeric Antigen Receptor T Cells (Day 0): IV administration of investigational therapy, BCMA/CD19 CAR T cells, over 10-20 minutes on day 0. Additional Doses: Eligible patients responding well to the initial BCMA/CD19 CAR-T cell infusion without unacceptable side effects and sufficient CAR-T cell availability may receive 2 or 3 additional doses.

Masking description

Open-label clinical trials are a category of clinical research where the masking is minimal or nonexistent. In such trials, both the participants and the researchers are fully aware of the treatment assignments, which means participants know the treatment they are receiving, and researchers are aware of each participant's treatment group.

Intervention model description

Patients enrolled in this clinical trial will receive a carefully designed treatment regimen. Before the infusion of BCMA and CD19 CAR-T cells, participants will undergo preconditioning chemotherapy. This chemotherapy serves to create an optimal environment for CAR-T cell therapy to effectively target and eliminate B cells. Following chemotherapy, participants will receive the infusion of CD19 and BCMA CAR-T cells.
