简要总结
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 GPRC5D or both sequentially in the treatment of Relapsed/ Refractory Multiple myeloma
详细描述
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 GPRC5D or both in patients with relapsed and refractory Multiple Myeloma. The study also aims to learn more about the function of CAR T cells and their persistence in Multiple myeloma patients.

盲法说明
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.

研究组 & 干预措施
CD19/GPRC5D CAR T cells, chemotherapy
Patients will be administered fludarabine phosphate intravenously (IV) over a 30-minute period on days -4 to -2. Additionally, cyclophosphamide will be administered intravenously (IV) over 60 minutes on day -2. Subsequently, patients will receive BCMA/GPRC5D CAR T cells intravenously (IV) over a duration of 10-20 minutes on day 0. Patients who exhibit positive responses to the initial dose of BCMA/GPRC5D CAR T cells, do not experience unacceptable side effects, and have a sufficient quantity of cells available may be eligible to receive 2 or 3 additional doses of BCMA/GPRC5D CAR T cells.
