CD147-CAR T for R/R T-NHL

Details and patient eligibility

About

The safety and preliminary effectiveness of CD147-CAR T cells in patients with relapsed or refractory T cell non-Hodgkin's lymphoma will be investigated in this pioneering study.

Full description

CD147 has been demonstrated higher and relatively specific expression on T cell non-Hodgkin's lymphoma. Preclinical studies have shown that CAR T cells targeting CD147 antigen can continuously eliminate Jurkat T-cell lymphoma in mice and extend survival without severe adverse events including hemolysis. Preliminary investigation of CD147-CAR T cells in solid tumors has started and shown an acceptable safety profile. The safety and preliminary effectiveness of CD147-CAR T cells in patients with relapsed or refractory T cell non-Hodgkin's lymphoma will be investigated in this pioneering study.
