Clinical Trial Summary

This is an open, single-arm, phase I clinical study to evaluate efficacy and safety of chimeric antigen receptor T cell immunotherapy (CAR-T) in the treatment of Non-hodgkin's lymphoma. A total of 100 patients are planned to be enrolled over a period of 3 years.

Description:

Chimeric antigen receptor (CAR)-modified T cells targeted against CD19 have demonstrated unprecedented successes in treating patients with hematopoietic and lymphoid malignancies. In this study, investigators will evaluate their safety and efficacy in patients with different types of hematopoietic and lymphoid malignancies. The primary goal is safety assessment including cytokine storm response and any other adverse effects. In addition, tumor targeting and disease status after treatment will also be evaluated.
