Safety and efficacy of first-line dacomitinib in Japanese patients with advanced non-small cell lung cancer.

ABSTRACT: In a subgroup of Japanese patients in the ARCHER 1050 randomized phase 3 trial, we evaluated the efficacy and safety and determined the effects of dose modifications on adverse events (AE) and therapy management of first-line oral dacomitinib 45 mg compared with oral gefitinib 250 mg, each once daily in 28-d cycles, in patients with EGFR-activating mutation-positive (EGFR-positive; exon 19 deletion or exon 21 L858R substitution mutations) advanced non-small cell lung cancer (NSCLC). The primary endpoint was progression-free survival (PFS; RECIST, version 1.1, by blinded independent review). In 81 Japanese patients (40 dacomitinib, 41 gefitinib), PFS was longer with dacomitinib compared with gefitinib (hazard ratio [HR], 0.544 [95% confidence interval {CI}, 0.307-0.961]; 2-sided P = .0327;
