About

Refractory and relapsed (R/R) acute lymphoblastic leukemia (ALL) patients with active disease always have a dismal outcome. Chimeric antigen receptor (CAR) T-cell therapy targeting to Cluster of Differentiation Antigen 19 (CD19) has been proved as a potent approach to attain remission in B-cell R/R patients. Therefore, the investigators conduct atrial to evaluate the the efficacy and safety of locally producing CAR T cells targeting CD19, and to analyze the outcome of enrolled B-cell ALL patients with active disease or persistent residual disease.
