Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

CD19/CD22-Dual-STAR-T

Arm Description

CD19/CD22-Dual-STAR-T cells are prepared via lentiviral infection. 5 days prior to infusion of Dual-STAR-T cells, subjects receive fludarabine at dose 30mg/m2/day and cyclophosphamide treatment at dose 500mg/m2 for 3 days and take a rest for 2 days before infusion. Dual-STAR-T cells will be intravenously infused with a escalated dose of 6E5、1E6、2E6、3E6 cells/kg.

Outcomes

Percentage of participants with adverse events.
Percentage of participants with adverse events.

Secondary Outcome Measures

Objective Remission Rate(ORR)
The percentage of participants who achieved complete remission(CR) and CR in over all participants.
Proliferation ratio of Dual-STAR-T cells

5. Study Description

Brief Summary
This is a single center, single arm, open-lable phase I study to determine the safety and efficacy of CD19/CD22-Dual-STAR-T cells in patients with refractory and relapsed B cell acute leukemia .
Detailed Description
Patients with B cell acute leukemia will be enrolled, and Subjects will receive cytoreductive chemotherapy with cyclophosphamide and fludarabine on days -5, -4 and -3 followed by infusion of Dual-STAR-T cells.Dual-STAR-T cells will be intravenously infused with a escalated dose of 6E5、1E6、2E6、3E6 cells/kg.The purpose of current study is to evaluate the clinical safety and efficacy of CD19/CD22-Dual-STAR-T cells therapy in patients with refractory and relapsed B-ALL.Safety and efficacy of Dual-STAR-T cells therapy will be monitored. The primary endpoint is the safety of Dual-STAR-T cells including the effect ratio of CRS and ICANS, ORR. The secondary endpoint is the Dual-STAR-T cell proliferation ratio and Dual-STAR gene copied number in peripheral blood(PB), and progression free survival(PFS ), overall-survival(OS) and duration of overall response(DOR).
