一线免疫治疗组合未能改善转移性NSCLC的总体存活率

2018-12-16 MedSci MedSci原创

根据ESMO免疫肿瘤学大会上发表的一项研究显示,使用durvalumab或durvalumab加tremelimumab治疗转移性非小细胞肺癌(NSCLC)的一线疗法并未改善患者的总生存期(OS)。

根据ESMO免疫肿瘤学大会上发表的一项研究显示,使用durvalumabdurvalumabtremelimumab治疗转移性非小细胞肺癌NSCLC)的一线疗法并未改善患者的总生存期(OS)。开放标签的IIIMYSTIC试验(NCT02453282)招募了1,118名没有EGFR致敏突变或ALK重排的患者,并且未接受过转移性NSCLC的先前免疫治疗或化疗。患者随机接受每4周静脉注射durvalumab 20 mg / kg,或durvalumab联合tremelimumab 1 mg / kg静脉注射,每4周一次,共4个周期,或铂类化疗最多6个周期。符合条件的患者允许使用培美曲塞维持治疗。

结果显示,与化疗相比,单独或与tremelimumab一起使用的Durvalumab并未改善OS或无进展生存期(PFS)。哥伦比亚大学医学中心医学博士Naiyer Rizvi报告说:虽然没有达到统计学意义,但接受durvalumab单药治疗的患者的中位总体生存改善为16.3个月,而PD-L1表达≥25%的患者接受化疗的中位总生存期仅为12.9个月。在该研究中,488名(44%)具有≥25%或更高的PD-L1表达,40%具有高肿瘤突变负荷(TMB)。
