The approval was based on findings from the phase III ARCHER 1050 trial, in which dacomitinib reduced the risk of disease progression or death by more than 40% and resulted in an average 6.5-month improvement in response duration compared with gefitinib (Iressa) as a first-line treatment for patients with advanced, EGFR
The median progression-free survival (PFS) for patients who received dacomitinib was 14.7 months compared with 9.2 months for participants who received gefitinib (HR, 0.59; 95% CI, 0.47-0.74; P
<.0001). The median duration of response (DOR) was 14.8 months with dacomitinib versus 8.3 months with gefitinib (HR, 0.40; 95% CI, 0.31-0.53; P
