欧洲杯微信买球阿斯利康提供了进一步的证据,证明了AZD9291在第一线和预处理的非小细胞肺癌中的潜力

8September 2016

AstraZeneca today announced updated data on AZD9291 in first-line patients with epidermal growth factor receptor mutation (EGFRm) positive advanced non-small cell lung cancer (NSCLC) and previously-treated patients with EGFRm T790M mutation-positive NSCLC. The data being presented today at the World Conference on Lung Cancer (WCLC) 2015 were from the AURA Phase I trial first-line cohort and two AURA Phase II studies.

数据表明,在一线环境中每天接受AZD9291的60例患者中,有72%(95%的置信区间(CI)58%至82%)在12个月时为无进展(PFS)。确认的总反应率(ORR)为75%(95%CI 62%至85%)。最长的响应持续时间(DOR)在18个月时进行。1

“虽然数据仍然是初步的,但AURA试验一线队列的这些最新结果进一步增强了AZD9291在治疗的EGFRM高级NSCLC患者中的潜力,” AURA First-First-First-First-First-First-agresh S. Ramalingam教授说。LINE队列数据和胸腔肿瘤学负责人和美国佐治亚州亚特兰大埃默里大学医学院医学肿瘤学主任。

还介绍了先前治疗的EGFRM T790M患者的两项AURA II期研究(AURA扩展和AURA2)的数据。尽管仍然初步,但这些研究表明,AZD9291的功效和耐受性概况与以前报告的数据一致。在Aura扩展中(n = 201),ORR为61%(95%CI 54%至68%);DOR和中位PFS无法计算(NC)。在AURA2(n = 210)中观察到一致的结果,ORR为71%(95%CI 64%至77%);DOR中位数为7.8个月(95%CI 7.1个月,NC),中位PFS为8.6个月(95%CI 8.3个月至9.7个月)。2-3

“这些数据提供了进一步的证据,证明AZD9291在未经治疗和预处理的EGFRM NSCLC患者中对AZD9291产生了持久的反应。”欧洲杯微信买球“数据支持我们加速发展策略的AZD9291,该战略以前所未有的速度从第一人类研究到美国食品和药物管理局以及其他监管提交。随着全球监管机构现在正在审查的AZD9291,我们有望尽快将这种创新医学带给患者,以满足这一关键需求。”

在这些研究中,AZD9291的安全性与今年早些时候报道的那样一致。在AURA一线队列中,不同剂量组的任何等级的最常见的全因不良事件(AE)包括皮疹(分组术语)(所有等级为77%,2%2%级≥3)和腹泻(73%均为73%等级,3%≥3)。这些AE还据报道是两种AURA II期研究中最常见的AE(Aura扩展,Rash 40%所有等级,1%≥3级,腹泻45%,所有等级,1%≥3; Aura 2,Rash 42%所有等级,1%≥3级,腹泻39%所有等级,1%级≥3)。1-3

Marketing authorisation applications for AZD9291 for the treatment of EGFR T790M mutation positive NSCLC have been submitted to the US Food and Drug Administration (FDA), the European Medical Agency (EMA) and other regulatory authorities. Recently, the FDA granted Priority Review to AZD9291, adding to the Breakthrough Therapy designation, Orphan Drug and Fast Track status already assigned by the regulatory body. AZD9291 has also been granted Accelerated Assessment by the EMA.

About AZD9291

AZD9291是一种高度选择性的,不可逆的抑制剂,即激活EGFRM和耐药性突变T790M,同时保留了野生型EGFR的活性。4AZD9291旨在实现对两个生物受体(称为胰岛素受体(IR)和胰岛素样生长因子受体(IGFR))的最低活性,以最大程度地减少高血糖症(高血糖)的潜力。高血糖可以导致需要其他药物治疗的患者。5

具有NSCLC的EGFRM形式的患者,在欧洲的NSCLC患者中有10-15%发生6和30-40%的亚洲NSCLC患者7,,,,对当前可用的EGFR-TKI的治疗特别敏感,该治疗阻断了驱动肿瘤细胞生长的细胞信号通路。8-10然而,肿瘤几乎总是对治疗产生抗药性,从而导致疾病进展。在大约三分之二的接受批准的EGFR-TKIS(吉非替尼)或厄洛替尼治疗的患者中,这种耐药性是由继发突变T790M引起的。11No targeted therapies are currently approved for the treatment of tumours with this resistance mutation.

As of June 1, 2015, of the more than 1200 patients dosed with AZD9291 across all studies, interstitial lung disease (ILD) grouped term events were reported in approximately 2.9% of patients (35 events): nine Grade 1, six Grade 2, 18 Grade ≥3, two currently ungraded. Of these, a total of four patients are reported to have died due to ILD (Grade 5).3

Osimertinib has recently been published by the World Health Organization (WHO) as the proposed International Nonproprietary Name (INN) for AZD9291, and may become formally adopted in November 2015. In the US, the American Medical Association accepted osimertinib as the United States Adopted Name (USAN).
