Overview
Brief Summary
This is a single arm, open-label, single-center prospective study to determine the safety and efficacy of Fast Dual CAR-T cells in patients diagnosed with CD19+ refractory/relapsed B cell non-Hodgkinlymphoma (R/R B-NHL).
Detailed Description
The main aim of the study is to determine the safety and efficacy of Fast Dual CAR-T in R/R B-NHL. Fast Dual CAR-T is an autologous dual chimeric antigen receptor T-cell (CAR-T) therapy that targets CD19 and B-cell maturation antigen (BCMA). The study will include 15 subjects to receive Fast Dual CAR-T single infusion.
