2019-04-04 佚名 药明康德

日前,百时美施贵宝(BMS)在美国亚特兰大举行的AACR年会上公布了该公司的抗PD-1重磅药Opdivo(nivolumab),作为2线疗法治疗非小细胞肺癌(NSCLC)患者的长期生存结果。汇集了CheckMate-017, -057, -063, 和-003四个3期临床试验中总计664名患者的试验结果表明,接受Opdivo治疗的患者在4年之后,总生存率(OS)达到14%。对于PD-L1表达指数大

日前,百时美施贵宝(BMS)在美国亚特兰大举行的AACR年会上公布了该公司的抗PD-1重磅药Opdivo(nivolumab),作为2线疗法治疗非小细胞肺癌NSCLC)患者的长期生存结果。汇集了CheckMate-017, -057, -063, 和-003四个3期临床试验中总计664名患者的试验结果表明,接受Opdivo治疗的患者在4年之后,总生存率(OS)达到14%。对于PD-L1表达指数大于1%的患者来说,四年OS为19%。PD-L1表达指数小于1%的患者的四年OS为11%。

肺癌是世界上导致癌症死亡的首要原因。而在中国,肺癌同样是发病率和死亡率最高的癌症。肺癌可分为非小细胞肺癌和小细胞肺癌两大类,其中NSCLC占肺癌患者总数的85%。被诊断出患有转移性肺癌的患者,5年生存率约为5%。

Opdivo是BMS公司开发的重磅抗PD-1免疫疗法。它已经获批治疗包括黑色素瘤,NSCLC,肾细胞癌等多种癌症类型。它是在中国获得批准的第一款用于治疗NSCLC的抗PD-1疗法,目前已经在中国上市。

综合CheckMate-017和-057的结果,接受Opdivo治疗的患者的4年OS达到14%,接受多西他赛(docetaxel)化疗治疗的对照组患者的OS只有5%。进一步分析表明,如果患者在接受Opdivo治疗6个月时达到完全或部分缓解,他们在4年时的生存率达到58%。与之相比,接受多西他赛治疗的患者这一指标为12%。

杜克癌症研究所癌症免疫疗法中心主任Scott Antonia博士评论道:“这些对大量曾接受治疗的晚期NSCLC患者群的分析第一次表明,对Opdivo的响应与长期生存益处相关。鉴于历史上这一患者群的5年生存率为5%,这些长期生存结果显得更有意义。”
