AZ的Tagrisso对肺癌的治疗具有持续作用

阿斯利康公司表示,Tagrisso作为一线治疗肺癌的"前所未有的无进展生存获益"通过后续的治疗方案得以延续。根据对全球III期FLAURA试验的数据进行的新分析,该试验评估Tagrisso(osimertinib)作为局部晚期或转移性表皮生长因子受体(EGFR)突变阳性患者的第一线发作的有效性和安全性 (EGFR酪氨酸激酶抑制剂(TKIs),厄洛替尼或吉非替尼)的药物无进展存活(PFS)益处在整个


阿斯利康公司表示,Tagrisso作为一线治疗肺癌的"前所未有的无进展生存获益"通过后续的治疗方案得以延续。

根据对全球III期FLAURA试验的数据进行的新分析,该试验评估Tagrisso(osimertinib)作为局部晚期或转移性表皮生长因子受体(EGFR)突变阳性患者的第一线发作的有效性和安全性 (EGFR酪氨酸激酶抑制剂(TKIs),厄洛替尼或吉非替尼)的药物无进展存活(PFS)益处在整个进展后续结果中持续存在。

在数据截止时,Tagrisso组中的患者较EGFR-TKI比较组中的患者更少(49%比77%),接受后续治疗的患者为29%比46%。

第一次随后治疗或死亡的中位时间为23.5个月,一线Tagrisso治疗组为13.5个月,而服用厄洛替尼或吉非替尼的患者为13.8个月。

此外,该公司指出,一线Tagrisso患者与比较组相比,几乎有一半的二次进展或死亡风险。

"来自FLAURA试验的新分析显示,使用Tagrisso的一线治疗具有超过后续治疗的持续作用,几乎减少二次进展或死亡的风险,"AZ首席医疗官Sean Bohen评论道。"这些发现基于Tagrisso临床上有意义的PFS益处,并加强其作为新护理标准的潜力。"
该分析在日内瓦的欧洲肺癌会议(ELCC)上提出。

Tagrisso是第三代不可逆EGFR酪氨酸激酶抑制剂,旨在抑制EGFR敏化和EGFR T790M耐药突变并在CNS中具有活性。

该药已在全球多个国家获得批准,作为EGFR T790M突变阳性晚期非小细胞肺癌患者的二线治疗药物,大西洋两岸也正在审查该药物用于一线治疗。

FDA在去年11月13日以加速批准的方式提前3个月批准了阿斯利康的Tagrisso(osimertinib,奥希替尼),用于二线治疗携带EGFR T790M突变的非小细胞肺癌(NSCLC)患者。FDA的批准依据是AURA项目中两项II期研究的结果,显示Tagrisso对接受EGFR抑制剂治疗后疾病恶化NSCLC患者的客观应答率(ORR)分别为57%和61%。所谓加速批准是FDA基于可预测药物临床获
