We conducted a prospective, randomized, phase 3
trial comparing crizotinib therapy with standard
chemotherapy in patients with advanced ALK-positive
non–small-cell lung cancer.
As compared with
standard second-line chemotherapy, treatment with
crizotinib resulted in significantly longer progression-
free survival, significantly higher response
rates, a significant reduction in symptoms, and a
significant improvement in global quality of life.
In this study, crizotinib was more effective than
either pemetrexed or docetaxel.
