Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Experimental: CART19 cell and auto-HSCT
CART19 cells transduced with a lentiviral vector to express anti-CD19 scFv TCRz:41BB administered by IV infusion. Auto-HSCT will be made about 6 mouths after CART19 cell is infused back to the patient.
Biological: CART19 cell and auto-HSCT
Phase 1 Clinical Study of CD19-directed Chimeric Antigen Receptor-modified T (CART19) Cells treatment for Adult Patient with Minimal Residual Disease(MRD) of B Cell Malignancies and then Autologous Hematopoietic Stem Cell Transplantation(Auto-HSCT). Subjects will receive 0.5-4 x 10^8 transduced CAR T cells as a split dose over three days as follows:Day 0, 10% fraction: 0.5-4x10^7 CART19 cells, Day 1, 30% fraction: 1.5x10^7-1.2x10^8 CART19 cells, Day 2, 60% fraction: 3x10^7-2.4x10^8 CART19 cells. Auto-HSCT will be made about 6 mouths after CART19 cell is infused back to the patient.
