Improvement in Overall Survival in a Randomized Study That Compared Dacomitinib With Gefitinib in Patients With Advanced Non-Small-Cell Lung Cancer and EGFR-Activating Mutations
Excerpt:In a multinational, multicenter study, patients age 18 years or older (≥ 20 years in Japan and Korea) who had an Eastern Cooperative Oncology Group performance status of 0 or 1 and newly diagnosed NSCLC with activating mutations in EGFR (exon 19 deletion or exon 21 L858R) were enrolled and randomly assigned in a 1:1 manner to dacomitinib (n = 227) or gefitinib (n = 225). Conclusion In patients with advanced NSCLC and EGFR activating mutations, dacomitinib is the first second-generation epidermal growth factor receptor tyrosine kinase inhibitor (TKI) to show significant improvement in OS in a phase III randomized study compared with a standard-of-care TKI.
