Progression free survival (PFS) and overall response rate were similar between treatment arms: median PFS was 4.8 months for ALIMTA plus cisplatin versus 5.1 months for gemcitabine plus cisplatin (adjusted hazard ratio 1.04; 95% CI 0.94-1.15), and overall response rate was 30.6% (95% CI 27.3- 33.9) for ALIMTA plus cisplatin versus 28.2% (95% CI 25.0-31.4) for gemcitabine plus cisplatin.
