去年7月份
AstraZeneca公布了
旗下MYSTIC临床研究初步结果
Durvalumab单药/联用Tremelimumab
对比
铂类化疗标准方案
一线治疗PD-L1≥25%
IV期转移性非小细胞肺癌
首要研究终点PFS未达成
但是OS研究还将继续
预期可以在上半年给出结果

到了年初
AZ将OS结果更新时间
推迟至二季度
今天
AZ公布了最新的OS结果
Imfinzi单药方案
HR=0.76
(97.54% CI 0.564-1.019; p=0.036)
Imfinzi联合Treme方案
HR=0.85
(98.77% CI 0.611-1.173; p=0.202)
We are encouraged to see that Imfinzi monotherapy activity is in-line with that of the anti-PD-1 class in previously-untreated patients with Stage IV non-small cell lung cancer; however, we are disappointed that these results missed statistical significance. We remain confident in Imfinzi as the cornerstone of our IO programme and continue to evaluate its potential in ongoing non-small cell lung cancer trials, including Imfinzi and Imfinzi plus tremelimumab in combination with chemotherapy.

最初的首要终点仅为PFS
后续加入OS作为共同首要终点
另外还有PD-L1+-指标
这个应该就是这样了
接下来
四季度还有NEPTUNE临床
这个Expansion
能给出怎么样的结果
期待
