Purpose<\/strong><\/p>\r\n\r\n\r\n\r\n ARCHER 1050, a randomized, open-label, phase III study of dacomitinib versus gefitinib in treatment-na\u00efve patients with advanced non\u2013small-cell lung cancer (NSCLC) and activating mutations in\u00a0EGFR<\/em>, reported significant improvement in progression-free survival with dacomitinib. The mature overall survival (OS) analysis for the intention-to-treat population is presented here.<\/p>\r\n\r\n\r\n\r\n <\/p>\r\n\r\n\r\n\r\n Patients and Methods<\/strong><\/p>\r\n\r\n\r\n\r\n In this multinational, multicenter study, patients age 18 years or older (\u2265 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\u00a0EGFR<\/em>\u00a0(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). Random assignment was stratified by race (Japanese, Chinese, other East Asian, or non-Asian) and\u00a0EGFR<\/em>\u00a0mutation type. The final OS analysis was conducted with a data cutoff date of February 17, 2017; at that time 220 deaths (48.7%) were observed.<\/p>\r\n\r\n\r\n\r\n Results<\/strong><\/p>\r\n\r\n\r\n\r\n During a median follow-up time of 31.3 months, 103 (45.4%) and 117 (52.0%) deaths occurred in the dacomitinib and gefitinib arms, respectively. The estimated hazard ratio for OS was 0.760 (95% CI, 0.582 to 0.993; two-sided\u00a0P<\/em>\u00a0= .044). The median OS was 34.1 months with dacomitinib versus 26.8 months with gefitinib. The OS probabilities at 30 months were 56.2% and 46.3% with dacomitinib and gefitinib, respectively. Preliminary subgroup analyses for OS that are based on baseline characteristics were consistent with the primary OS analysis.<\/p>\r\n\r\n\r\n\r\n Conclusion<\/strong><\/p>\r\n\r\n\r\n\r\n In patients with advanced NSCLC and\u00a0EGFR<\/em>\u00a0activating 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. Dacomitinib should be considered one of the standard treatment options for these patients.<\/p>\r\n\r\n\r\n\r\n <\/p>\r\n\r\n\r\n\r\n
