Brief Summary:
Evaluation the safety and efficacy of CD19/CD20 bispecific CAR-T cells in patients with relapsed/refractory B cell lymphoma

Condition or disease Intervention/treatment Phase
B-Cell Lymphoma Stage I Refractory Relapsed Biological: CD19/CD20 bispecific CAR-T cells Phase 1

Detailed Description:
CART cell therapy has become the treatment of choice for patients with relapsed/ refractory B cell lymphoma. Currently, CAR-T cells approved for relapsed/refractory B-cell lymphoma are mainly CAR19-T cells. Nearly half of patients who relapse after treatment with CAR19-T cells are caused by tumor cell antigen escape. Dual-target CAR-T cells targeting CD19 and CD20 may reduce the recurrence rate after treatment. This study was to evaluate the efficacy and safety of CD19/CD20 bispecific CAR-T cells in patients with relapsed/refractory B cell lymphoma.

Biological: CD19/CD20 bispecific CAR-T cells
collecting blood for CAR-T cells culture three days later, FC regimen (fludarabine 30mg/m2/d x 3, cyclophosphamide 600-800mg/m2/d x 2) another two days later, transfusing CD19/CD20 bispecific CAR-T cell with a dose of 1-3x106/kg

Primary Outcome Measures :
  1. occurrence of study related adverse events [ Time Frame: one year ]
    safety of CAR-T cells

Secondary Outcome Measures :
  1. objective response rate [ Time Frame: three months ]
    proportion of patients with complete response and partial response

  2. survival time of CAR-T cells in vivo [ Time Frame: one year ]
    from the time of CAR-T cells transfusion to the first time that CAR-T cells could not be measured in vivo

  3. progression-free survival [ Time Frame: one year ]
    the enrollment to the first time that disease progression is detected
