2015-01-14 黄蕾蕾 中国医学论坛报

研究目的通过对两项非盲、随机、Ⅲ期试验的数据分析,评估阿法替尼(afatinib)对EGFR突变阳性肺腺癌患者总生存(OS)的影响。研究方法研究纳入未经治疗的EGFR突变阳性ⅢB或Ⅳ期肺腺癌患者,其中LUX-Lung 3队列345例,LUX-Lung 6队列364例。按2:1随机分配予以阿法替尼或化疗(LUX-Lung 3:培美曲塞+顺铂;LUX-Lung 6:吉西他滨+顺铂),根据EGFR突变类

研究目的


通过对两项非盲、随机、Ⅲ期试验的数据分析,评估阿法替尼(afatinib)对EGFR突变阳性肺腺癌患者总生存(OS)的影响。

研究方法

研究纳入未经治疗的EGFR突变阳性ⅢB或Ⅳ期肺腺癌患者,其中LUX-Lung 3队列345例,LUX-Lung 6队列364例。按2:1随机分配予以阿法替尼或化疗(LUX-Lung 3:培美曲塞+顺铂;LUX-Lung 6:吉西他滨+顺铂),根据EGFR突变类型(del19,Leu858Arg或其他)和人种来源(仅在LUX-Lung 3队列)分层。在出现209例(LUX-Lung 3)和237例(LUX-Lung 6)死亡时对意向性人群的总生存(OS)数据设计了分析。

研究结果

LUX-Lung 3和LUX-Lung 6队列的中位随访时间分别为41个月[四份位间距(IQR):35~44个月]和33个月(IQR:31~37个月),死亡数213例(62%)和246例(68%)。

LUX-Lung 3队列中,阿法替尼组和化疗(培美曲塞+顺铂)组的中位OS期分别为28.2个月(95%CI:24.6~33.6)、28.2个月(20.7~33.2),风险比(HR)为0.88(0.66~1.17,P=0.39)。LUX-Lung 6队列中,阿法替尼组和化疗(吉西他滨+顺铂)组的中位OS期分别为23.1个月(20.4~27.3)、23.5个月(18.0~25.6),HR为0.93(0.72~1.22,P=0.61)。

然而,在预先计划的分析中,del19阳性肿瘤患者的OS在两项研究中均为阿法替尼组显著长于化疗组:LUX-Lung 3队列中,阿法替尼组和化疗组的中位OS期分别为33.3个月(26.8~41.5)、21.2个月(16.3~30.7),HR为0.54(0.36~0.79,P=0.0015);LUX-Lung 6队列中,阿法替尼组和化疗组的中位OS期分别为31.4个月(24.2~35.3)、18.4个月(14.6~25.6),HR为0.64(0.44~0.94,P=0.023)。与之相反的是,EGFR Leu858Arg阳性肿瘤患者在两项研究中阿法替尼组和化疗组间无显著差异:LUX-Lung 3队列中,阿法替尼组和化疗组的中位OS期分别为27.6个月(19.8~41.7)、40.3个月(24.3~上限未估计),HR为1.30(0.80~2.11,P=0.29);LUX-Lung 6队列中,阿法替尼组和化疗组的中位OS期分别为19.6个月(17.0~22.1)、24.3个月(19.0~27.0),HR为1.22(0.81~1.83,P=0.34)。

不良反应

两项研究中,最常见的阿法替尼相关3~4级不良反应有皮疹或痤疮[LUX-Lung 3,33例(16%);LUX-Lung 6,35例(15%)],腹泻[33例(14%),13例(5%)],甲沟炎[26例(11%),仅见于LUX-Lung 3队列],口腔炎或黏膜炎[13例(5%),仅见于LUX-Lung 6队列]。LUX-Lung 3队列中,最常见的化疗相关3~4级不良反应有中性粒细胞减少[20例(18%)]、乏力[14例(13%)]和白细胞减少[9例(8%)];而在LUX-Lung 6队列中,最常见的是中性粒细胞减少[30例(27%)]、呕吐[22例(19%)]和白细胞减少[17例(15%)]。

研究结论

尽管阿法替尼并未改善两项研究总人群的OS,但其延长了del19 EGFR突变患者的OS。阿法替尼对Leu858Arg EGFR突变患者无效的结果提示,EGFR的del19突变与Leu858Arg突变所致疾病间存在差异,在未来的研究中应分别分析这两个亚群。

ESMO 2014:肺鳞癌、头颈鳞癌:阿法替尼好戏连台

本届ESMO年会上,有关新型不可逆ErbB家族抑制剂阿法替尼的两项临床研究(摘要号:1222O,LBA29_PR)结果接连发布,证实其在复发或难治性肺鳞癌患者中的PFS和DCR方面较厄洛替尼显著更好;在铂类基础的化疗方案失败的转移性头颈鳞状细胞癌(HNSCC)患者中,阿法替尼也较甲氨蝶呤显著改善了PFS。 鳞癌约占NSCLC的30%,患者的二线治疗选择不多,研究进展也有限。 LUX

ASCO 2014:阿法替尼可改善非小细胞肺癌患生存

阿法替尼是一种口服、不可逆的ErbB家族阻滞剂,可阻断EGFR、HER2、ErbB3和 ErbB4信号通路。LUX-Lung 3(LL3)研究比较了阿法替尼与培美曲塞/顺铂用于全球345例EFFR突变的非小细胞肺癌(NSCLC)患者治疗效果;LUX-Lung 6(LL6)研究比较了阿法替尼与吉西他滨/顺铂用于364例亚洲患者的疗效。 分析显示,相比于化疗组,阿法替尼可提高所有EGFR突变人群无进展
