近日,勃林格殷格翰肿瘤产业管线遭遇挫折,其抗癌药Gilotrif由于在头颈癌临床试验中表现不佳,勃林格决定终止两项临床试验

2013年,Gilotrif (afatinib)获得FDA批准,用于治疗EGFR阳性的非小细胞肺癌,而近期该药物又在晚期肺鳞状细胞癌方面获得美国和欧洲批准,这也是该药物收获的第二个适应症。

勃林格的肿瘤产业管线历史不长,而Gilotrif (afatinib)在2013年的上市对这家德国制药巨头而言非常重要,一度是勃林格的重磅抗癌药。因此,勃林格也在一直试图扩大Gilotrif的适应症,以获得更多的市场份额。

勃林格在未接受化疗或放疗的局部晚期头颈癌患者中验证了afatinib的有效性,希望afatinib能够延长患者的生存期,然而,在名为LUX-Head & Neck 2和4的两项临床试验都表明,患者并没有从治疗中获益。不过勃林格还没有完全放弃Gilotrif (afatinib)的头颈癌适应症,据悉勃林格报道过一项在复发性或转移性头颈癌患者临床试验(LUX-Head and Neck 1)中的积极数据,此外针对亚洲患者的临床试验(LUX-Head and Neck 3) 仍在进行。

当前EGFR抑制剂市场竞争激烈,原本勃林格对Gilotrif (afatinib)寄予厚望,而这两项临床试验结果的不良数据公布,对勃林格扩大该药物的适应症无疑是沉重的打击。目前在非小细胞肺癌中,Gilotrif (afatinib)的主要竞争对手是阿斯利康的Iressa (gefitinib)和罗氏/安斯泰来的Tarceva (erlotinib) ,尤其随着阿斯利康的3代TKI抑制剂Tagrisso (osimertinib)的推广,Gilotrif面临的压力会越来越大。Tagrisso目前已被批准为非小细胞肺癌的2线用药,而目前阿斯利康已经有充分的临床数据支持该药物被批准为1线用药。
