Clinical Study of SL19+22 CAR-T Cells for Relapsed or Refractory Non-Hodgkin Lymphoma

SL19+22 injection is a CAR-T product independently developed by Senlang that targets both CD19 and CD22. Based on the traditional CAR T treatment regimen, the CAR structure was designed, and the activation mode of T cells was changed by using cytokine combination amplification and improved transfection technology. The Main research objectives: To evaluate the safety and efficacy of SL19+22 in patients with recurrent or refractory non-Hodgkin's lymphoma The Secondary research objectives: To investigate the cytokinetic characteristics of SL19+22 in patients with recurrent or refractory non-Hodgkin's lymphoma.
