This is a single-center, prospective clinical study evaluating safety and efficacy of C-CAR011 treatment in subjects with ALL after HSCT

A study evaluating safety and efficacy of CBM.CD19-targeted chimeric antigen receptor T cells (C-CAR011) treatment in subjects with acute lymphoblastic leukemia(ALL) after hematopoietic stem cell transplantation（HSCT）. The amount of cells received：1.0-5.0×10^6CAR+T cells/kg
