中文摘要

靶向 CD19 的CAR-T(CAR-T)细胞疗法治疗复发/难治性(R/R)B 急性淋巴细胞白血病(B-ALL)已显示前景,但细胞因子释放综合征(CRS)仍是显著副作用。

这项回顾性队列研究调查了托珠单抗在 45 例 R/R B-ALL 患者 CAR-T 相关 CRS 管理中的应用。

其中 17 例接受托珠单抗治疗;与未用药患者相比,其 3 级 CRS 持续时间显著缩短。此外,10 例患者细胞因子水平下降。重要的是,托珠单抗未损害 CAR-T 细胞扩增或疗效,也未增加不良事件发生率。

研究结果提示,托珠单抗可能是减轻 R/R B-ALL 患者 CAR-T 相关 CRS 的有效且安全策略,有望改善患者结局和生存。

CD19 chimeric antigen receptor T (CAR-T) cell therapy has shown promise in treating relapsed or refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL), but cytokine release syndrome (CRS) remains a significant side effect.

This retrospective cohort study investigated the use of tocilizumab for managing CAR-T-related CRS in 45 R/R B-ALL patients.

Of these, 17 patients received tocilizumab, resulting in a significant reduction in the duration of grade 3 CRS compared to those who did not receive the drug. Additionally, 10 patients showed decreased cytokine levels.Importantly, tocilizumab did not impair CAR-T cell expansion or efficacy, nor did it increase the incidence of adverse events.

These findings suggest that tocilizumab may be an effective and safe strategy for mitigating CAR-T-related CRS in R/R B-ALL patients, potentially improving patient outcomes and survival.
