What was measured

DoR was defined as the time from the first observation of an objective tumor response (CR or PR) until first observation of progressive disease (PD) according to RECIST v1.1 or death from any cause. CR: disappearance of all target, non-target lesions; normalization of tumor marker level; and reduction in all lymph nodes size to \<10 mm. PR: \>/=30% decrease in the SoD of target lesions (taking as reference the baseline SoD). PD: \>/=20% relative increase and \>/=5 mm of absolute increase in the SoD, taking as reference the smallest SoD recorded since treatment started; 1 or more new lesion(s); and/or unequivocal progression of non-target lesions. Duration of response was estimated by Kaplan-Meier method and 95% CI was assessed using the method of Brookmeyer and Crowley. Participants who did not progress or die after a confirmed objective response were censored at the date of their last tumor assessment.

Analysis population: Analysis was performed on RE population (IRC) participants with documented 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.
