Study Description

Brief summary:

This is a single center, single arm, open-lable phase 1 study to determine the safety and efficacy of CD19-CAR-T cells in patients with relapsed or refractory B-cell lymphoma.

  • Condition or Disease:Lymphoma
  • Intervention/Treatment: Biological: MC-19PD1 CAR-T cells
