2012年phase II 的实验，对比 特罗凯和804 的效果。病人都是有1，2次化疗的。
结论: 无论PFS 和OS，804 都显示出比特罗凯更好的效果。但改善程度很小。
其中野生型 EFGR 对比为 2.2 vs 1.84， 有EFGR 突变的 为3.7 vs 1.9。

Abstract
PURPOSE:
This randomized, open-label trial compared dacomitinib (PF-00299804), an irreversible inhibitor of human epidermal growth factor receptors (EGFR)/HER1, HER2, and HER4, with erlotinib, a reversible EGFR inhibitor, in patients with advanced non-small-cell lung cancer (NSCLC).
PATIENTS AND METHODS:
Patients with NSCLC, Eastern Cooperative Oncology Group performance status 0 to 2, no prior HER-directed therapy, and one/two prior chemotherapy regimens received dacomitinib 45 mg or erlotinib 150 mg once daily.
RESULTS:
One hundred eighty-eight patients were randomly assigned. Treatment arms were balanced for most clinical and molecular characteristics. Median progression-free survival (PFS; primary end point) was 2.86 months for patients treated with dacomitinib and 1.91 months for patients treated with erlotinib (hazard ratio [HR] = 0.66; 95% CI, 0.47 to 0.91; two-sided P = .012); in patients with KRAS wild-type tumors, median PFS was 3.71 months for patients treated with dacomitinib and 1.91 months for patients treated with erlotinib (HR = 0.55; 95% CI, 0.35 to 0.85; two-sided P = .006); and in patients with KRAS wild-type/EGFR wild-type tumors, median PFS was 2.21 months for patients treated with dacomitinib and 1.84 months for patients treated with erlotinib (HR = 0.61; 95% CI, 0.37 to 0.99; two-sided P = .043). Median overall survival was 9.53 months for patients treated with dacomitinib and 7.44 months for patients treated with erlotinib (HR = 0.80; 95% CI, 0.56 to 1.13; two-sided P = .205). Adverse event-related discontinuations were uncommon in both arms. Common treatment-related adverse events were dermatologic and gastrointestinal, predominantly grade 1 to 2, and more frequent with dacomitinib.
CONCLUSION:
Dacomitinib demonstrated significantly improved PFS versus erlotinib, with acceptable toxicity. PFS benefit was observed in most clinical and molecular subsets, notably KRAS wild-type/EGFR any status, KRAS wild-type/EGFR wild-type, and EGFR mutants. |
