What was measured

CDoR was defined as the time from the first observation of a CNS objective response (CR or PR) until first observation of CNS progression as assessed by IRC according to RECIST v 1.1 or death from any cause. CR: disappearance of all CNS lesions. PR: \>/=30% decrease in the SoD of measurable CNS lesions (taking as reference the baseline SoD). CNS progression: \>/=20% increase in the SoD of measurable CNS lesions (with an absolute increase of at least 5 mm), taking as reference the baseline SoD; 1 or more new CNS lesion(s); and/or unequivocal progression of non-measurable CNS lesions. CDoR was estimated by Kaplan-Meier method and 95% CI was assessed using the method of Brookmeyer and Crowley.

Analysis population: Analysis was performed on safety population participants with measurable CNS lesions at baseline and who had CNS objective response as assessed by IRC according to RECIST v1.1.

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.
