一代EGFR抑制 LUX-Lung 3期试制比较了HER后裔不可逆的抑制阿法替尼与标准复发在无权疗程的后半期EGFR等位基因感染性的非小细胞心脏病(NSCLC)症状之中的效果。阿法替尼和“一代EGFR抑制”同可逆的、特异的EGFR过氧化物激酶抑制(比如埃罗替尼和吉非替尼)相比,究竟都能缺少非常很大的病理或许呢? 研究课题摘要 Ramalingam及其熟人开展了一项2期随机试制,在接纳过EGFR抑制首次疗程的后半期NSCLC症状之中如此一来比较dacomitinib和厄洛替尼,该研究课题同北美的多数不带有EGFR等位基因活性的症状很大涉及。(J Clin Oncol. 2012;30:3337-3344) 该研究课题纳入了188由此可知接纳过非EGFR靶向疗程的复发的症状。除了基线体力状态高分2(dacomitinib第三组19由此可知,厄洛替尼第三组3由此可知)、经常出现EGFR等位基因(dacomitinib第三组19由此可知,厄洛替尼第三组11由此可知)、接纳过2两种复发方案的症状为数(dacomitinib第三组40由此可知,厄洛替尼第三组29由此可知)因素所外,两个试制第三组较适度。所有研究课题对象按1:1随机分第三组,分别口服dacomitinib 45mg/日或厄洛替尼15mg/日。该研究课题的主要终点是无令人满意生存期(PFS)。 多个试制常量揭示dacomitinib非常有压倒性。转发百余人分别为17.0 vs 5.3%(P=0.011),病理单单结合病情稳定超过24周的前提转发百余人分别为29.4% vs 14.9%(P=0.014),同时,dacomitinib第三组的转发时间尺度也非常有压倒性(16.6月末 vs 9.2月末)。Dacomitinib 第三组的PFS有统计分析压倒性(之中位PFS,29.月末 vs 1.9月末;HR,0.66;P=0.012)。关键的是,几乎在所有病理和原子亚型之中揭示PFS单单,包括KRAS等位基因感染性症状(之中位PFS,3.7月末 vs 1.9月末;HR,0.55;P=0.006),KRAS和EGFR野生型(之中位PFS,2.2月末 vs 1.8月末;HR,0.61;P=0.043),EGFR等位基因感染性症状(虽然第二第三组之中位PFS均为7.4月末,但是HR为0.46非常利于dacomitinib第三组,P=0.098)。第二第三组的总生存期(OS)无统计分析很大相似之处,但是dacomitinib第三组的之中位OS较厄洛替尼第三副队长2个月末(9.5月末 vs 7.4月末;HR,0.80;P=0.205)。 造成了的同十分相似主要是dacomitinib第三组较差的致癌性反应亦会,包括过敏(73% vs 48%),痤疮十分相似皮炎(64% vs 57%),口腔炎(29% vs 11%),甲沟炎(26% vs 8%),和其他不常见的类药物。另外,Dacomitinib第三组无需增大剂量(41% vs 17%)的症状和复发(7由此可知 vs 2由此可知)的症状较大。 卫报 如果dacomitinib的致癌性反应亦会可被降低的话将是心脏病的希望。事实上,该本品在广泛应用的NSCLC人群之中要优于厄洛替尼,尤其是在KRAS等位基因和/或EGFR野生型症状之中,这表明dacomitinib或许亦会使一个有价值的疗程必需。我们所想早就进行的研究课题dacomitinib 和厄洛替尼的3期随机随机对照试制的结果,在它成为接纳过疗程的后半期NSCLC症状不能容忍疗程的一个有效必需早先,对于病理医生来说学习如何管理该本品的类药物是很关键的。与厄洛替尼涉及的拓展书本:JCO:Dacomitinib优于厄洛替尼?厄洛替尼延至非小细胞心脏病症状复发时间【ASCO 2012】厄洛替尼主要用途疗程使EGFR等位基因NSCLC症状单单厄洛替尼主要用途疗程可使EGFR等位基因NSCLC症状受益EGFR等位基因指导厄洛替尼疗程后半期心脏病非常多资讯请点击:有关厄洛替尼非常多资料库Randomized Phase II Study of Dacomitinib (PF-00299804), an Irreversible Pan–Human Epidermal Growth Factor Receptor Inhibitor, Versus Erlotinib in Patients With Advanced Non–Small-Cell Lung CancerPurpose This randomized, open-label trial compared dacomitinib (PF-00299804), an irreversible inhibitor of human epidermal growth factor receptors (EGFR)/HER1, HER2, and HER4, with erlotinib, a reversible EGFR inhibitor, in patients with advanced non–small-cell lung cancer (NSCLC).Patients and Methods Patients with NSCLC, Eastern Cooperative Oncology Group performance status 0 to 2, no prior HER-directed therapy, and one/two prior chemotherapy regimens received dacomitinib 45 mg or erlotinib 150 mg once daily.Results One hundred eighty-eight patients were randomly assigned. Treatment arms were balanced for most clinical and molecular characteristics. Median progression-free survival (PFS; primary end point) was 2.86 months for patients treated with dacomitinib and 1.91 months for patients treated with erlotinib (hazard ratio [HR] = 0.66; 95% CI, 0.47 to 0.91; two-sided P = .012); in patients with KRAS wild-type tumors, median PFS was 3.71 months for patients treated with dacomitinib and 1.91 months for patients treated with erlotinib (HR = 0.55; 95% CI, 0.35 to 0.85; two-sided P = .006); and in patients with KRAS wild-type/EGFR wild-type tumors, median PFS was 2.21 months for patients treated with dacomitinib and 1.84 months for patients treated with erlotinib (HR = 0.61; 95% CI, 0.37 to 0.99; two-sided P = .043). Median overall survival was 9.53 months for patients treated with dacomitinib and 7.44 months for patients treated with erlotinib (HR = 0.80; 95% CI, 0.56 to 1.13; two-sided P = .205). Adverse event-related discontinuations were uncommon in both arms. Common treatment-related adverse events were dermatologic and gastrointestinal, predominantly grade 1 to 2, and more frequent with dacomitinib.Conclusion Dacomitinib demonstrated significantly improved PFS versus erlotinib, with acceptable toxicity. PFS benefit was observed in most clinical and molecular subsets, notably KRAS wild-type/EGFR any status, KRAS wild-type/EGFR wild-type, and EGFR mutants.
