Detailed Description
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.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: PD1-CD19-CART Patients undergo leukapheresis. Patients will receive a lymphodepletion chemotherapy with cyclophosphamide and fludarabine 4-6 days before CART infusion. A dose of PD1-CD19-CART will be infused on day 0. |
Biological: PD1 specific integrated anti-CD19 Chimeric Antigen Receptor T Cells
Gene editing autologous T cells with anti-CD19 ScFv expression and knockout of PD1

Outcome Measures
Primary Outcome Measures
- Dose-limiting toxicity (DLT) [up to 28 days after T cell infusion]
Incidence of toxicity graded using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03
Secondary Outcome Measures
- Objective response rate (ORR) [Baseline up to 3 months after T cell infusion]
Proportion of patients in whom a response among complete response and partial response as defined by standard disease-specific criteria, will be observed.
- Progress free survival (PFS) [3 months]
Assessed using modified Lugano classification response criteria for lymphoma (2014)
