通用型EGFR抗病毒 LUX-Lung 3期实验比较了HER家族不等价的抗病毒阿法替尼与规格治疗在未经病患的更早EGFR基因感染性的非小细胞癌症(NSCLC)症状之中的效果。阿法替尼和“通用型EGFR抗病毒”同等价的、特异的EGFR代谢物磷酸化抗病毒(比如埃罗替尼和吉非替尼)相对来说,是否能够提供更是总体的以外科某种程度呢? 分析摘要 Ramalingam及其威尔森透过了一项2期随机实验,在接纳过EGFR抗病毒首次病患的更早NSCLC症状之中这样一来比较dacomitinib和厄洛替尼,该分析同澳大利亚的一般来说不具有EGFR基因活性的症状总体相关。(J Clin Oncol. 2012;30:3337-3344) 该分析扩展到了188同上接纳过非EGFR靶向病患的治疗的症状。除了孔径体力状态平均分2(dacomitinib第一组19同上,厄洛替尼第一组3同上)、出现EGFR基因(dacomitinib第一组19同上,厄洛替尼第一组11同上)、接纳过2两种治疗方案的症状比例(dacomitinib第一组40同上,厄洛替尼第一组29同上)因素以外,两个实验第一组较基本。所有分析对象按1:1随机分第一组,分别抗生素dacomitinib 45mg/日或厄洛替尼15mg/日。该分析的主要站起是无困难重重生存期(PFS)。 多个实验参数表明dacomitinib更是有竞争者。需要的话百余人共五17.0 vs 5.3%(P=0.011),以外科获利结合病情平衡最多24周的客观需要的话百余人共五29.4% vs 14.9%(P=0.014),同时,dacomitinib第一组的需要的话一段时间内也更是有竞争者(16.6年初 vs 9.2年初)。Dacomitinib 第一组的PFS有社会学竞争者(之中位PFS,29.年初 vs 1.9年初;HR,0.66;P=0.012)。重要的是,几乎在所有以外科和原子流感病毒之中表明PFS获利,包括KRAS基因感染性症状(之中位PFS,3.7年初 vs 1.9年初;HR,0.55;P=0.006),KRAS和EGFR野生型(之中位PFS,2.2年初 vs 1.8年初;HR,0.61;P=0.043),EGFR基因感染性症状(虽然两第一组之中位PFS均为7.4年初,但是HR为0.46更是亦然dacomitinib第一组,P=0.098)。两第一组的总生存期(OS)无社会学总体差异,但是dacomitinib第一组的之中位OS较厄洛替尼第一组长2个年初(9.5年初 vs 7.4年初;HR,0.80;P=0.205)。 遭遇的挑战主要是dacomitinib第一组较低的毒性重排,包括腹泻(73% vs 48%),痤疮样皮炎(64% vs 57%),口腔炎(29% vs 11%),甲沟炎(26% vs 8%),和其他不常见的症状。另以外,Dacomitinib第一组并不需要降低剂量(41% vs 17%)的症状和停药(7同上 vs 2同上)的症状少。 评论 如果dacomitinib的毒性重排可被减低的话将是癌症的希望。事实上,该药物在广泛的NSCLC人群之中要胜过厄洛替尼,更是是是在KRAS基因和/或EGFR野生型症状之中,这证明dacomitinib某种程度会使一个引人注目的病患必需。我们期待正在透过的分析dacomitinib 和厄洛替尼的3期随机双盲实验的结果,在它成为接纳过病患的更早NSCLC症状深知病患的一个有效性必需在此之前,对于以外科医生来说学习如何管理该药物的症状是很重要的。与厄洛替尼相关的扩充朗读:JCO:Dacomitinib胜过厄洛替尼?厄洛替尼延长非小细胞癌症症状复发时间【ASCO 2012】厄洛替尼辅助病患使EGFR基因NSCLC症状获利厄洛替尼辅助病患可使EGFR基因NSCLC症状给与EGFR基因个人兴趣厄洛替尼病患更早癌症更是多的资讯劝点击:有关厄洛替尼更是多资讯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.
