Обзор

A Phase Ⅱ Clinical Study Evaluating the Efficacy and Safety of Human CD19 Targeted T Cells Injection (CD19 CAR-T) Therapy for R/R B-NHL. Patients will be given a conditioning chemotherapy regimen of fludarabine and cyclophosphamide followed by a single infusion of CD19 CAR+ T cells.

Подробное описание

Subjects with relapsed and refractory B-cell non-Hodgkin's lymphoma would be selected if subjects meet all criteria evaluated by physical exams, blood tests, electrocardiograph, computedtomography （CT）/magnetic resonance Imaging(MRI)/positron emission tomography（PET）, tumor assessments, etc. Subjects would be hospitalized to receive the infusion of CD19 CAR+ T cells after lymphodepleting regimen, with the observation and evaluation of efficacy and safety.
