What was measured

CNS DOR was defined as the time from when response (CR or PR) was first documented to first documented disease progression or death, whichever occurred first. DOR was evaluated for participants who had a best overall response (BOR) of CR or PR.

Analysis population: ITT population included all participants randomized in the study, irrespective of whether or not they received study drug. Number analyzed indicates number of participants with a BOR of CR or PR.

Groups in this outcome

Alectinib

Participants received alectinib at 600 mg orally BID from Visit 0 (baseline) until disease progression, unacceptable toxicity, withdrawal of consent or death.

Crizotinib

Participants received crizotinib at 250 mg orally BID from Visit 0 (baseline) until disease progression, unacceptable toxicity, withdrawal of consent or death.
