简要总结
To observe the long-term efficacy and safety of dual-target chimeric antigen receptor T cells in the treatment of refractory relapsed B cell hematologic tumors (at least 2 years).
详细描述
This study is open single-arm prospective clinical study To relapse/refractory blood B cell tumor patients as the subjects, according to the expression of tumor cells, gives the corresponding double targets CART cell injection treatment, follow-up observation of the adverse reactions and the treatment effect of the drug to the data (at least 2 years), assessment of double targets CAR - T Long-term efficacy and safety of cell injection
