简要总结
Evaluation the safety and efficacy of CD19/CD20 bispecific CAR-T cells in patients with relapsed/refractory B cell lymphoma
详细描述
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.
