[Challenges and strategies for improving efficacy in CAR-T therapy].

ABSTRACT

CAR-T cell therapy targeting CD19 and BCMA for relapsed or refractory hematopoietic tumors has been adopted in routine practice and has shown dramatic results. However, half of patients who achieve remission with CAR-T therapy eventually relapse, and thus efforts to improve the efficacy of CAR-T therapy are gaining momentum. Notably, studies have described innovative technologies that enable control of cell kinetics after infusion, which is not possible with conventional CAR-T therapies. In this article, we review the challenges of CAR-T cell therapy and the development of new technologies.
