CAR-T 细胞疗法作为二线治疗,与 SOC 相比,在 R/R DLBCL 中似乎能有效实现更高的缓解率并延缓疾病进展。
近期评估CAR-T(CAR-T)细胞疗法作为二线治疗对比标准治疗(SOC)用于复发/难治性弥漫大B细胞淋巴瘤(R/R DLBCL)患者的III期试验结果不一致,促使进行了一项meta分析,以评估CAR-T 细胞疗法在该情况下的有效性。
采用随机效应meta分析合并效应估计值,以比较CAR-T 细胞疗法与SOC。采用频率学网络meta分析方法进行混合治疗比较。
对三项试验共865例患者的Meta分析显示,与SOC相比,CAR-T 细胞治疗显著改善无事件生存期(EFS:HR:0.51;95% CI:0.27-0.97;I2:92%)、无进展生存期(PFS:HR:0.47;95% CI:0.37-0.60;I2:0%)。尽管CAR-T 细胞治疗有潜在总生存期(OS)改善的信号,但两组间差异无统计学意义(HR 0.76;95% CI:0.56至1.03;I2:29%)。混合治疗比较显示,与tisa-cel相比,liso-cel(HR:0.37;95% CI:0.22-0.61)和axi-cel(HR:0.42;95% CI:0.29-0.61)具有显著的EFS获益。
Random-effects meta-analysis was conducted to pool effect estimates for comparison between CAR-T cell therapy and SOC. Mixed treatment comparisons were made using a frequentist network meta-analysis approach.
Meta-analysis of three trials with 865 patients showed significant improvement in event-free survival (EFS: HR: 0.51; 95% CI: 0.27-0.97; I2: 92%), progression-free survival (PFS: HR: 0.47; 95% CI: 0.37-0.60; I2: 0%) with CAR-T cell therapy compared to SOC. Although there was a signal of potential overall survival (OS) improvement with CAR-T cell therapy, the difference was not statistically significant between the two groups (HR 0.76; 95% CI: 0.56 to 1.03; I2: 29%). Mixed treatment comparisons showed significant EFS benefit with liso-cel (HR: 0.37; 95% CI: 0.22-0.61) and axi-cel (HR: 0.42; 95% CI: 0.29-0.61) compared to tisa-cel. DISCUSSION: CAR-T cell therapy, as a second-line treatment, appears to be effective in achieving higher response rates and delaying the disease progression compared to SOC in R/R DLBCL.
