Efficacy and Safety Evaluation of U01(ssCART-19) in B-Cell Lymphoma

Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) are critical complications in CAR T-cell therapy. Research highlights IL-6 as a central driver of CRS, as activated CAR T-cells secrete this cytokine, which in turn stimulates monocytes to produce additional IL-6. To mitigate this risk, ssCART-19-a modified anti-CD19 CAR T-cell therapy-incorporates small hairpin RNA (shRNA) technology to silence the IL-6 gene, thereby reducing IL-6 secretion by both CAR T-cells and monocytes. This study aims to assess the safety and efficacy of the U01 (ssCART-19) therapy in patients with refractory or recurrent B-cell lymphoma .
