Chimeric antigen receptor (CAR)-modified T cells (CAR-T cells) have the capabilities to recognize tumor associated antigen and kill tumor cells specifically. CAR-T therapy showed great effect on patients with relapsed or refractory B cell malignancies. CAR consists of single chain variable fragment (scFv) and activation domain of T cell. In preclinical study, the researchers constructed a second generation CAR containing CD137 costimulatory domain. This study aims to evaluate the safety and effectiveness of anti-CD19 CAR-T cells in patients with relapsed or refractory B cell Malignancies.
This is a single arm, open-label, phase 1/2 study to evaluate the safety and efficacy of anti-CD19 CAR-T cells in patients with relapsed or refractory B cell Malignancies.
