纳武利尤单抗是完全人源性抗PD-1抗体,伊匹单抗是完全人源性抗细胞毒性T淋巴细胞抗原4(CTLA-4)抗体,这两种药物是具有不同但互补作用机制的免疫检查点抑制剂。在黑色素瘤患者和肾细胞癌患者中,纳武利尤单抗+伊匹单抗联合治疗达到了超过既往标准治疗的总生存期(OS)。

此前发表在《新英格兰医学杂志》(NEJM)的试验提示,非小细胞肺癌(NSCLC)患者使用纳武利尤单抗+伊匹单抗组的缓解率高于纳武利尤单抗单药治疗组,尤其在肿瘤表达PD-L1的患者中。在NSCLC患者中,与伊匹单抗的其他用药方案相比,与纳武利尤单抗联合用药时,伊匹单抗的剂量和给药频率较低,因此不良事件较少,同时较好的疗效得到保持。

在广泛病变的小细胞肺癌(ED-SCLC)中,一线铂类化疗的反应率是稳健的,但反应缺乏持久性。那么纳武利尤联合伊匹单抗是否能使ED-SCLC患者获益呢?最近,由来自美、德、韩、法等多国联合发表在ASCO期刊《临床肿瘤学杂志》(JCO)上的结果给出了答案。

CheckMate 451是一项双盲III期试验,评估了纳武利尤联合伊匹单抗和纳武利尤单药治疗作为ED-SCLC一线化疗后的维持治疗的疗效差异。纳入了东部合作肿瘤学组评分0-1、一线化疗≤4个周期后无进展ED-SCLC患者。

将参与者随机分配(1:1:1)至联合用药组或单药治疗组。前者为纳武利尤 1 mg/kg加伊匹3 mg/kg,每3周1次,持续12周,随后纳武利尤 240 mg每2周1次给药;后者为仅用纳武利尤240 mg每2周1次或安慰剂持续≤2年或直至进展或不可接受的毒性治疗。

研究的主要终点是纳武利尤联合伊匹单抗组与安慰剂相比的的总生存期(OS)。次要终点进行了分级检验。

结果共有834名患者接受随机分配治疗。最短随访时间为8.9个月。总的来说,与安慰剂相比,纳武利尤联合伊匹单抗治疗组患者OS没有显著延长(HR=0.92;95%CI,0.75-1.12)。同时,纳武利尤单药组OS中位为10.4个月,也没有显著性差异(HR=0.84,95% CI,0.69-1.02)。

进一步分析显示,与安慰剂相比,纳武利尤联合伊匹单抗治疗组患者无进展生存期有差异(HR=0.72,95% CI,0.60~0.87),单用纳武利尤组为0.67(95% CI,0.56~0.81)。

在肿瘤突变负担≥13个突变/MB的患者中,观察到纳武利尤联合伊匹单抗治疗组的OS获益趋势。同时,纳武利尤组(11.5%)和安慰剂(8.4%)相比,纳武利尤联合伊匹单抗治疗组(52.2%)3-4级治疗相关不良事件发生率更高。

综上,对于一线化疗无进展的ED-SCLC患者,纳武利尤联合伊匹单抗治疗的维持治疗没有延长OS。
