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. Data for this outcome were reported for 'alectinib 600 mg' and 'alectinib other than 600 mg' groups as planned.

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

Groups in this outcome

Alectinib 600 mg (Fed): Phase I (20/40/150 mg)

Participants received single dose of 20 or 40 or 150 mg alectinib capsules orally to make a dose of 600 mg on Cycle 1 Day -3 and then received 600 mg BID dose for 3-weekly cycles until disease progression, death or withdrawal for any other reasons.

Alectinib Other Than 600 mg (Fasted/Fed): Phase I

Participants received single dose of 20 or 40 or 150 mg alectinib capsules orally to make a dose of 240, 300, 460, 760, or 900 mg on Cycle 1 Day -3 and then received 300, 460, 760, or 900 mg BID dose for 3-weekly cycles until disease progression, death or withdrawal for any other reasons.
