NEJM:Durvalumab单抗治疗III期非小细胞肺癌

2017-11-16 zhangfan MedSci原创

研究认为,对于III期非小细胞肺癌患者,Durvalumab治疗可显著延长患者无进展生存期

大多数局部晚期,不可手术切除的非小细胞肺癌NSCLC)患者,即便接受放化疗联合治疗仍不能缓解疾病进展。在近日的III期临床研究中,研究人员考察了PD-1单抗Durvalumab对接受2轮以上铂基础放化疗后未出现进展的III期NSCLC患者的疗效。

患者以2:1随机分组接受Durvalumab(10 mg/Kg)或安慰剂,每2周1次,持续12个月。在患者放疗后1-42天接受药物。主要终点为无进展生存期、总生存期,次要终点包括12和18个月无进展生存率,客观响应率、死亡或远端转移时间和安全性。

709名患者参与研究,其中治疗组473人,安慰组236人。治疗组平均无进展生存期为16.8个月 (95% CI, 13.0-18.1)而安慰剂组仅为5.6个月。疾病进展或死亡的危险比为0.52(95% CI, 0.42-0.65)。12个月以及18个月患者无进展生存率分别为55.9% vs 35.3%;44.2% vs 27.0%。治疗组的治疗响应率(28.4% vs 16.0%)、响应持续时间(18个月患者持续响应率72.8% vs 46.8%)以及远端转移或死亡时间(23.2个月vs 14.6 个月)显著改善。治疗和对照组3或4级不良事件率分别为29.9%和26.1%,最常见的3或4级不良事件为肺炎,治疗组15.4%以及对照组9.8%的患者因不良事件终止研究。

研究认为,对于III期非小细胞肺癌患者,Durvalumab治疗可显著延长患者无进展生存期。
