What was measured

DOR was defined for responders (CR or PR) as the time from when response was first documented, to first documented disease progression (according to RECIST v1.1) or death (whichever occurred first). Participants who did not progress or did not die after they had a response were censored at date of their last tumor measurement. Progressive disease (PD): at least 20% increase in the sum of diameters of target lesions compared to the smallest sum of diameters on-study and absolute increase of at least 5 mm, progression of existing non-target lesions, or presence of new lesions. Refer "Outcome Measure 2" for the definition of CR and PR. The median time to the event was estimated using the methodology of Kaplan-Meier. Brookmeyer-Crowley method was used to calculate 95% CI.

Analysis population: Phase II RE population. 'Overall Number of Participants Analyzed' = participants evaluable for this outcome measure.

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.
