What was measured

CNS response was assessed by IRC according to RECIST v1.1. CNS Objective response was defined as percentage of participants with a CR or PR. CR was defined as disappearance of all CNS lesions. PR was defined as \>/=30% decrease in the SoD of measurable CNS lesions (taking as reference the baseline SoD). 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.
