Figure 2. Progression-free Survival.
Shown are Kaplan–Meier estimates of progression-free survival among patients with advanced, ALK-rearranged non–small-cell lung cancer (NSCLC) who received ceritinib at doses of 400 to 750 mg daily. In these 114 patients, the median progression-free survival was 7.0 months (blue). In the subgroup of 80 patients who had received crizotinib previously, the median progression-free survival was 6.9 months (orange). In the subgroup of 34 patients who had not received crizotinib previously, the median progression-free survival was not reached (green). Vertical lines on the survival curves indicate censoring of data.
