Study Details

Study Description

Brief Summary

This is an open label, single-site, dose-escalation study in up to 20 participants with relapse/refractory B-NHL. This study aims to evaluate the safety and efficacy of the treatment with PD1-CD19-CART.

Condition or Disease Intervention/Treatment Phase
  • Biological: PD1 specific integrated anti-CD19 Chimeric Antigen Receptor T Cells
N/A

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.

  • Outcome Measures

    Primary Outcome Measures

    1. 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

    1. 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.

    2. Progress free survival (PFS) [3 months]

      Assessed using modified Lugano classification response criteria for lymphoma (2014)
