What was measured

CDoR: time from the CNS objective response until CNS progression as assessed by IRC according to RANO criteria or death from any cause. CR: complete disappearance of all enhancing measurable, non-measurable disease; stable/improved non-enhancing lesions; no new lesions; no corticosteroids, and clinically stable/improved. PR: \>/=50% decrease compared to screening in SPD of enhancing measurable lesions; no progression of non-measurable disease; no new lesions; no corticosteroids, and clinically stable/improved. Progression: \>/=25% increase in SPD of enhancing measurable lesions compared to best response on study; stable/increasing doses of corticosteroids; significant increase in non-enhancing lesions not caused by co-morbid events; any new lesions; progression of non-measurable disease; or clinical deterioration not attributable to other non-tumor causes. CDoR was estimated by Kaplan-Meier method and 95% CI was assessed using 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 RANO criteria.

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.
