About

This is a single center, single arm, open-lable phase 1 study to determine the safety and efficacy of CD19-CAR-T cells in patients with relapsed or refractory B-cell lymphoma.

Full description

In this single-center, open-label, nonrandomized, no control, prospective clinical trial, appoximately 15 relapsed or refractory B-cell lymphoma patients will be enrolled. Side effects of CD19 CAR T cells therapy will be monitored.
