奥希替尼的循证地位已由多项III期确立:FLAURA显示一线治疗EGFR敏感突变晚期NSCLC中位PFS 18.9对10.2个月(HR 0.46)[2],最终OS 38.6对31.8个月[4];AURA3在T790M耐药人群对比铂类培美曲塞取得PFS 10.1个月[3];ADAURA又将其推进到术后辅助[5]。但耐药不可避免、机制高度异质,进展后除化疗外长期缺乏明确选择[6],这正是本届ESMO 2026被反复讨论的缺口。
会上分量最重的是Dr. Shun Lu报告、同步发表于NEJM的研究:奥希替尼治疗后进展、伴MET过表达和/或扩增的EGFR+ NSCLC,奥希替尼+savolitinib优于化疗——1746例筛查、338例随机,PFS 7.6对5.4个月(HR 0.55),OS HR 0.68,12个月OS 70%对53%。@dplanchard称之为奥希替尼后的重大里程碑与新的治疗标准,主张所有进展的EGFRm患者都做MET检测,同时坦言药物可及性是患者回国后最难的一步。
ctDNA是另一条主线。FLAURA2探索性分析[1]显示第6周血浆EGFRm清除率在联合化疗组88%、奥希替尼单药组89%,几乎相同;在清除者中联合治疗仍改善PFS(HR 0.52,另有帖引HR 0.51),即早期清除是预后因素而非预测因素,不能据此省略化疗;基线ctDNA检测不到的约20%患者,单药mPFS可达30个月。PACE-LUNG II期采取另一思路:第3周ctDNA阳性(72/255)者加4周期化疗,自奥希替尼起算mPFS 17.8个月、OS 31.5个月,虽无对照但结果令人鼓舞。
主站新闻层面,NEJM以Ahead of Print确认了savolitinib组合的发表,未披露试验设计等额外细节;独立报道则补充了百利天恒iza-bren(EGFR×HER3双抗ADC)联合奥希替尼一线中国II期更新:ORR 100%、18个月PFS率92.2%、中位随访22.8个月;另有奥希替尼±环孢素A的II期试验(NCT07874490)启动招募、计划60例。就认知推进而言,savolitinib组合把[6]所述进展后缺乏选择的困境带入PFS与OS双获益、被专家称为新标准的阶段,FLAURA2则划清了ctDNA清除率的解读边界。局限同样明确:PACE-LUNG无对照,FLAURA2为探索性分析,可及性被现场专家点为最大现实障碍。
