Ann Oncol:奥希替尼治疗T790M阳性NSCLC脑转移:两项II期研究合并分析

2018-02-13 Wrangx 肿瘤资讯

NSCLC多见中枢神经系统(CNS)转移。早期临床研究显示奥希替尼可有效治疗CNS转移。为评价奥希替尼CNS活性,合并分析AURA扩展(NCT01802632)和AURA2 (NCT02094261)两项II期研究中CNS转移数据。

NSCLC多见中枢神经系统(CNS)转移。早期临床研究显示奥希替尼可有效治疗CNS转移。为评价奥希替尼CNS活性,合并分析AURA扩展(NCT01802632)和AURA2 (NCT02094261)两项II期研究中CNS转移数据。既往EGFR TKI治疗进展的T790M阳性NSCLC,奥希替尼80mg,每日一次 (n=411)。稳定无症状脑转移可入组,允许既往接受过CNS治疗,要求基线≥1处可测量的CNS病灶,独立影像评估中心(BICR)评价CNS的疗效。首要研究终点为BICR的ORR,次要终点为DoR、DCR和PFS。

纳入基线CNS转移患者128例,可评估疗效50例,确认CNS  ORR和DCR分别为54%和92%,疗效与既往放疗无关。中位CNS的DoR(22%)未成熟(1~15个月),在第9个月时,75%患者仍维持有效。中位随访11个月,中位CNS  PFS未达到(95%CI 7个月~不可计算)。安全性数据与总体人群类似。研究结论为奥希替尼可有效治疗CNS转移,DCR较高,ORR令人鼓舞。
