Treatment-naive patients with stage IIIB or IV ALK-rearranged nonsquamous NSCLC were randomized in a one-to-one ratio to receive either oral ceritinib 750 mg/day (fasted) daily or intravenous chemotherapy...Of 376 randomized patients, 158 (42.0%) were Asian (ceritinib arm: N = 76; chemotherapy arm: N = 82)….The median PFS (by BIRC assessment) was 26.3 months (95% confidence interval [CI]: 8.6-not estimable) and 10.6 months (95% CI: 6.7-15.0), with an estimated 34% risk reduction in PFS (hazard ratio = 0.66, 95% CI: 0.41-1.05) in the ceritinib arm versus chemotherapy arm.
