Brief summary
A Clinical Study to Explore the Safety, Efficacy and Cellular Metabolic Kinetics of CT1195E CAR-T Cells Injection in Patients with Relapsed/Refractory B-Cell Neoplasms
Detailed description
This is a single-arm, open-label, dose exploratory clinical study to evaluate the safety, efficacy, cellular Metabolic Kinetics of CT1195E CAR-T Cells in patients with relapsed/refractory B-cell Non-Hodgkin's Lymphoma (R/R B-NHL) and relapsed/refractory B-cell acute lymphoblastic leukemia (R/R B-ALL). It is planned to enroll around 20-30 participants.
