Lancet Oncol:阿法替尼作为复发或转移性鳞状细胞癌患者的二线治疗

2015-05-03 范伟译 MedSci原创

背景:复发或转移性鳞状细胞头颈部癌(HNSCC)一线铂方案治疗后有不良预后,且有很少的治疗方案选择。阿法替尼,不可逆转ERBB家族抑制剂,在II期临床研究中显示有疗效。我们旨在评估阿法替尼与甲氨蝶呤用于复发或转移性头颈部鳞状细胞癌铂治疗后作为二线治疗的有效性和安全性。方法:在19个国家101个中心进行的开放标签的、III期的随机对照试验,我们招募18岁或以上,组织学或细胞学上证实为鳞状细胞头颈部癌

背景:复发或转移性鳞状细胞头颈部癌(HNSCC)一线铂方案治疗后有不良预后,且有很少的治疗方案选择。阿法替尼,不可逆转ERBB家族抑制剂,在II期临床研究中显示有疗效。我们旨在评估阿法替尼与甲氨蝶呤用于复发或转移性头颈部鳞状细胞癌铂治疗后作为二线治疗的有效性和安全性。

方法:在19个国家101个中心进行的开放标签的、III期的随机对照试验,我们招募18岁或以上,组织学或细胞学上证实为鳞状细胞头颈部癌复发或转移的患者,或两种都有或一线铂疗法后,没有进行抢救手术或放疗,东部肿瘤合作组织(ECOG)体能状态为0或1的患者。先前不止一个系统性治疗方案都未能进行;先前以EGFR-靶标抗体的疗法治疗(但不是EGFR-靶标的酪氨酸激酶抑制剂)允许进行了。我们随机分配2:1的比例符合条件的患者接受口服阿法替尼(40毫克/天)或静脉注射甲氨蝶呤(每周40 mg/m2),由ECOG体能状态或先前EGFR-靶标抗体治疗复发或转移性疾病进行分层。随机化集中交互式语音或基于web的反应系统。临床医生和患者非双盲的分配治疗;肿瘤反应的独立审查是在双盲的方式下完成的。主要终点是通过独立的中央成像审查委员会对无进展生存期进行评估。疗效分析进行意向处理分析人群而完成,安全性分析是接受至少一个剂量的药物研究完成的。这个正在进行的研究已在临床试验注册ClinicalTrials.gov,number NCT01345682。

结果:在2012年1月10日和2013年12月12日之间,我们招收了483名患者, 随机分配322名接受阿法替尼,161名接受甲氨蝶呤。随访中位期6.7个月后(IQR 3.1-9.0),阿法替尼组的无进展生存期相比甲氨蝶呤组更长,阿法替尼组(中位期2.6个月[95%置信区间2.0 - 2.7]相比甲氨蝶呤组1.7个月(95%置信区间1.5 - 2.4);危险比[HR]0.80[95%置信区间0.65 - 0.98],p = 0.030)。最常见的3或4级药物相关的不良反应有皮疹或痤疮(阿法替尼组320例中31例[10%]和甲氨蝶呤组160例没有一例),腹泻(30例(9%) Vs 3例[2%]),口腔炎(20例(6%) Vs 13例[8%]),疲劳(18例(6%) Vs 5例[3%]),中性粒细胞减少(1例(< 1%)对11例[7%]);严重不良反应发生在44例(14%)阿法替尼治疗的患者上和18例(11%)甲氨蝶呤治疗的患者上。

结论:阿法替尼与无进展生存期的显著改善有关联,且有可控制的安全性数据。这些发现为治疗这类患者人群提供了重要的新见解,支持进一步的研究不可逆的ERBB家族抑制剂用于鳞状细胞头颈部癌的治疗。

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

Lancet Oncol:阿法替尼治疗鳞状细胞癌

患有复发性或者转移性的头颈部鳞状细胞癌的病人经过铂类药物治疗的预后并不理想,而且目前也没有明确的标准疗法。在一项回顾性分析中,头颈部鳞状细胞癌的平均存活时间大概为1.8个月。甲氨蝶呤、紫杉烷和西妥昔单抗被单独使用或者联用作为铂类药物治疗失败后的二线疗法,尽管这种疗法缺乏随机试验的证明。阿法替尼是一种不可逆的ERBB受体家族阻断剂,在头颈部鳞状细胞癌的2期临床试验中展现出了良好疗效。 为此,研

Oncologist:阿法替尼治疗EGFR-TKIs获益的非小细胞肺癌患者进展后的经验分析

背景:作为ErbB家族非可逆性抑制剂,阿法替尼相比一线化疗方案,在EGFR突变的非小细胞肺癌患者中呈现一定的优越性。同时,阿法替尼在EGFR-TKIs(EGFR酪氨酸激酶抑制剂)治疗进展后仍然表现出疗效。本试验报道了体恤用药组织中的非小细胞肺癌患者应用阿法替尼后的研究结果。研究方法:本试验研究对象入选标准:非小细胞肺癌患者一线及以上化疗进展后、接受EGFR-TKIs的EGFR突变或曾经临床获益后进

Lancet Oncol:阿法替尼未改善EGFR突变阳性肺腺癌患者总生存

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
