研究组 & 干预措施
Treatment group
Dose Escalation:After enrollment ,Participants complete the PBMC apheresis,then complete the Lymphocyte clearance,and then receive the dose climning test: 3×10e6/kg,6 ×10e6/kg,9×10e6/kg.
Dose Expansion:Participants receive a single dose (at the MTD determined).
干预措施: CLL1 CAR-T (Drug)
结局指标
主要结局
Evaluation of Safety
时间窗: Up to 2 years after CLL1 CAR-T infusion
Count the Incidence of adverse events
Changes in cytokine level after CLL1 CAR-T infusion
时间窗: Up to 2 years after CLL1 CAR-T infusion
Calculate the change of cytokine level in peripheral blood by flow cytometry after CLL1 CAR-T infusion. Cytokines include IL-2、IL-6、IL-10、IFN-γ.
次要结局
- Complete response rate(CRR)(Up to 2 years after CLL1 CAR-T infusion)
- Partial response Rate (PRR)(Up to 2 years after CLL1 CAR-T infusion)
- Overall response Rate(ORR)(Up to 2 years after CLL1 CAR-T infusion)
