This is a single arm, open-label, single-center prospective study to determinethe safety and efficacy of CTA30X UCAR-T cells in patients diagnosed with CD19+ refractory/relapsed B Hematologic Malignancies
Full description
The main aim of the study is to determine the safety and efficacy of CTA30X UCAR-T in R/R B Hematologic Malignancies. CTA30X UCAR-T is an allogeneic chimeric antigenreceptor T-cell (CAR-T) therapy that targets CD19 and B-cell Hematologic Malignancies. The study will include 72 subjects to receive CTA30X UCAR-T singleinfusion.
