The purpose of this study is to assess the feasibility, safety and efficacy of universal CAR T cell therapy against CD19-positive hematological malignancies using a novel CD19-specific CAR T cell product, 4SCAR19U T cells. The study also aims to learn more about the function of the 4SCAR19U T cells and their persistence in patients. This is a phase I trial enrolling patients from multiple clinical centers.
Chimeric antigen receptor (CAR) T cell therapy has proven effective in treating B cell malignancies. However, the application itself is still limited by the high cost and long preparation time which often do not meet the urgent need of patients. In addition, some patients may suffer from long-term immunosuppression caused by tumor microenvironment or after radiotherapy and chemotherapy, resulting in exhaustion, aging and functional defects of the autologous T cells, which will eventually affect the quality of the CAR-T cells and affect the clinical efficacy. The 4SCAR19U T cells are genetically engineered and manufactured in bulk amount that can be supplied off-the-shelf without being custom made from individual patients. The immediate availability of the CAR-T cells makes clinical treatment convenient and timely for rapid progressing disease or for the highly immune suppressed patients. This application can be time- and cost-effective. This novel approach may also overcome problems of functionally defective autologous T cells. The purpose of this clinical trial is to assess the feasibility, safety and efficacy of the 4SCAR19U T cell product in hematological malignancies. Another goal of the study is to learn more about the function of this novel product and its persistence in the patients
