简要总结
The aim of this study was to analyze the safety and efficacy of CD3-CD20 bispecific antibody-based therapy in combination with CD19-CAR-T cells for the treatment of relapsed and refractory B-cell Non-Hodgkin's （B-NHL） lymphoma.
The main questions it aims to answer：
- The safety of CD3-CD20 bispecific antibody-based therapy in combination with CD19-CAR-T cells in B-NHL;
- The effect of different doses of bispecific antibody maintenance therapy on CAR-T cell expansion.
详细描述
The study was divided into two phases:
In the previous phase Ib clinical study, the bispecific antibody was used for bridging therapy to reduce the Neoplasm load, followed by CART cell therapy. After CART cell therapy, low-dose bispecific antibody was used for maintenance, in order to explore the safe resistance of bispecific antibody combined with CAR-T cell therapy and further explore the effect of bispecific antibody combined with CAR-T cell therapy on CART cell expansion; Phase II study will expand the sample study to further clarify whether bispecific antibody combined with CAR-T cell therapy can further deepen the efficacy of CAR-T.
