What was measured

CNS response was assessed by IRC according to RANO criteria. CNS Objective response: percentage of participants with a CR or PR that was confirmed by repeat assessments \>/=4 weeks after initial documentation. CR was defined as complete disappearance of all enhancing measurable, non-measurable disease; stable or improved non-enhancing lesions; no new lesions; no corticosteroids (or only physiologic replacement dose), and clinically stable or improved. PR was defined as \>/=50% decrease compared to screening in the sum of the products of the diameters (SPD) of enhancing measurable lesions; no progression of non-measurable disease (enhancing and non-enhancing lesions); no new lesions; no corticosteroids (or only physiologic replacement dose), and clinically stable or improved. The 95% CI was computed using Clopper-Pearson method.

Analysis population: Analysis was performed on safety population participants with measurable CNS lesions at baseline.

Groups in this outcome

Alectinib

Participants received alectinib at a dose of 600 mg via capsule, orally, twice daily, continuously starting on Day 1 Cycle 1 (in 28-day cycles) until PD, death, or withdrawal for any other reasons, whichever occurred first. After PD, participants were allowed to continue treatment with alectinib as per the discretion of the treating physician.
