What was measured

COR rate (CORR) was defined as the percentage of participants who had a CR or PR of the baseline central nervous system (CNS) lesions, based on RECIST v.1.1. CNS responses according to RECIST v1.1 did not have to be confirmed. CR was defined as disappearance of all CNS lesions. PR was defined as \>=30% decrease in the sum of diameters of measurable CNS lesions (taking as reference the baseline sum of diameters). 95% CI was computed using the Clopper-Pearson method.

Analysis population: Phase II safety population. 'Overall Number of Participants Analyzed' = participants with measurable CNS lesions at baseline based on RECIST v1.1 according to IRC.

Groups in this outcome

Alectinib 600 mg (Fed): Phase II

Participants received 600 mg alectinib capsules orally BID from Cycle 1 Day 1 for 3-weekly cycles until disease progression, death or withdrawal for any other reasons.
