欧洲杯微信买球阿斯利康(Astrazeneca)的塔格里索(Tagrisso)在ESMO 2017年国会(ESMO)的一线EGFR突变肺癌中显示出潜力作为新的护理标准

第三阶段的Flaura试验结果表明,Tagrisso将进展或死亡的风险降低了一半以上,在所有亚组中,包括有或没有脑转移的患者,均无益处

前所未有的中值无进展生存期(PFS)为18.9个月,而目前的护理标准为10.2个月

临床上敏感的初步总体生存益处

欧洲杯微信买球阿斯利康(Astrazeneca)提出了III期Flaura试验的完整结果塔格里索’s(osimertinib) clear作为新的护理标准(SOC)的潜力,该标准在成年患者的第一线治疗中,具有局部促成或转移性表皮生长因子受体(EGFR)的非小细胞肺癌(NSCLC)。

Results of the Phase III FLAURA trial were included at the Presidential Symposium I of the European Society of Medical Oncology (ESMO) 2017 Congress in Madrid, Spain, and demonstrate a superior, clinically-meaningful PFS advantage with塔格里索与当前的SOC EGFR-TKIS(Erlotinib或Gefitinib)相比。

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: “The FLAURA data are truly exciting. Until now, even with the therapeutic advances offered by the first- and second-generation EGFR inhibitors, less than 20% of EGFR mutation-positive NSCLC patients survive for five years. The FLAURA data suggest early and sustained benefit with塔格里索这有可能显着影响长期的患者结局,并有助于满足剩下的大量未满足需求。”

美国亚特兰大埃默里大学Winship癌症研究所的Flaura试验首席研究员Suresh S. Ramalingam博士说:“ osimertinib的Flaura数据可能会导致对患者治疗的重大范式转移EGFR突变阳性晚期肺癌。与其他常用的EGFR抑制剂相比,该试验不仅证明了osimertinib的疗效有效提高,而且副作用曲线也对osimertinib更有利”。

Flaura数据的其他亮点包括:

  • Superior progression-free survival (PFS):患者塔格里索had less than half the risk of progression or death compared with patients on erlotinib or gefitinib (hazard ratio [HR] 0.46; 95% confidence interval [CI] 0.37-0.57; p<0.0001). The median PFS was 18.9 months for patients on塔格里索vs.10.2 months for patients in the comparator arm.
  • 临床上有25%的临床初步总生存率(OS)数据:OS的危险比为0.63(95%CI:0.45-0.88; P = 0.0068)有利塔格里索。临时分析时的总生存数据为25%(21%的患者塔格里索had died and 30% of the patients on the comparator arm had died). The p-value of 0.0068 was not below the threshold of 0.0015 required for statistical significance at the current level of maturity. A final OS analysis is planned at a later stage.
  • PFS改进各个子组一致:PFS的改进塔格里索在所有预先指定的患者亚组中均保持一致,进展或死亡的风险至少降低了40%,包括在研究进入时患有/没有中枢神经系统(CNS)转移的患者,亚洲/非亚洲患者,患者,患者有/没有先前的吸烟史,外显子19缺失/L858R的患者。
  • 令人印象深刻的响应时间(DOR)和客观响应率(ORR):Patients treated with塔格里索比较臂(17.2个月比8.5个月)和比较臂的ORR(肿瘤收缩率的测量值)为80%比76%(比值比1.28 [0.85-- [0.85--1.93],p = 0.2335)。

Flaura安全数据塔格里索与先前的临床试验中观察到的那些相符,≥3级不良事件率(AES)。在接受治疗的患者中塔格里索,最常见的AE是腹泻(58%[2%≥3])和皮肤干燥(32%[<1%≥3]),在比较臂组中,最常见的AES是腹泻(57%)[3%≥3])和痤疮皮炎(48%[5%≥3])。患者塔格里索,33.7%的AE级为≥3级,比较臂中有44.8%,患者的患者为13.3%塔格里索had an AE leading to treatment discontinuation compared with 18.1% in the comparator arm.

AstraZeneca is in discussions with global health authorities regarding regulatory submissions for塔格里索based on the FLAURA data. A status of regulatory submissions is usually provided with the Company’s quarterly results announcement.

塔格里索目前在包括美国,欧盟,日本和中国在内的50多个国家 /地区获得了批准,因为由于EGFR T790M耐药性突变,在接受EGFR-TKI治疗后进展后进步后,NSCLC患者进行了第二线治疗。

NOTES TO EDITORS

关于EGFR突变的NSCLC

Lung cancer is the leading cause of cancer death among both men and women, accounting for about one-quarter of all cancer deaths, more than breast, prostate and colorectal cancers combined. Approximately 10-15% of patients in the US and Europe, and 30-40% of patients in Asia have EGFRm NSCLC. These patients are particularly sensitive to treatment with currently-available EGFR-TKIs, which block the cell signalling pathways that drive the growth of tumour cells. However, tumours almost always develop resistance to EGFR-TKI treatment, leading to disease progression. Approximately half of patients develop resistance to approved EGFR-TKIs such as gefitinib and erlotinib due to the resistance mutation, EGFR T790M.塔格里索还针对这种导致疾病进展的次要突变。还需要提高CNS功效的药物,因为大约25%的EGFRM NSCLC患者在诊断时具有脑转移,在诊断后的两年内增加到约40%。

关于弗拉拉

弗拉拉评估了塔格里索在先前未经治疗的患者中,每天80mg口头每天一次与护理标准EGFR-TKI(每天150mg口服,每天150mg,每天一次)或Gefitinib [250mg口服,每天一次])。该试验是一项双盲,随机研究,在30个国家 /地区有556名患者。

该试验的主要终点是PFS,次要终点包括OS,ORR,DOR,疾病控制率(DCR),安全性和与健康相关的生活质量(HRQOL)的度量。
