简要总结
This is an open label, single-site, dose-escalation study in up to 25 participants with relapse/refractory B-NHL. This study aims to evaluate the safety and efficacy of the treatment with PD1-CD19-CART.
详细描述
PD1-CD19-CART is a kind of chimeric antigen T cell targeting CD19 with both CD19-CAR gene integration and also PD1 knockout by one-step gene-editing. After completion of study treatment, subject participation for this study will be followed up to 15 years post T cell infusion.

结局指标
主要结局
MTD
时间窗: up to 28 days after T cell infusion
MTD will be determined based on DLTs observed during the first 28 days of study treatment.
RP2D
时间窗: up to 28 days after T cell infusion
RP2D will be determined based on MTD and efficiency during the first 28 days of study treatment.
次要结局
- Progress free survival (PFS)(Baseline up to 3 months after T cell infusion)
- Objective response rate (ORR)(Baseline up to 3 months after T cell infusion)
