Time frame
Every 8 weeks, up to 12 months after the last participant was randomized or until the target number of events (deaths) was met, whichever was later. (Overall survival data was collected till 24 Jan 2014 which was date of observation of the 571st death)

What was measured

Overall survival was defined as the time from the date of randomization to the date of death for participants. If a participant discontinued study medication for reasons other than radiologic disease progression, the participant was followed for tumor response until radiologic disease progression or initiation of new anticancer therapy.

Analysis population: Analysis was performed in ITT population. For participants who were alive as of the overall survival cutoff date, their survival was censored on the cutoff date post consent.

Groups in this outcome

TAS-102

Participants received TAS-102 orally with a starting dose of 35 mg/m\^2/dose BID based on BSA along with BSC. The first dose of TAS-102 was administered in the morning of Day 1 of each cycle and the last dose was administered in the evening of Day 5, followed by rest on Day 6 and 7, treatment was repeated for next week starting from Day 8 to Day 12, followed by a 16-day rest starting from Day 13 to Day 28 (1 treatment cycle = 28 days). Participants received study medication until any of the discontinuation criteria were met.

Placebo

Participants orally received TAS-102 matching placebo BID dose along with BSC with the first dose administered in the morning of Day 1 of each cycle and the last dose administered in the evening of Day 5, followed by rest on Day 6 and 7, treatment was repeated for next week starting from Day 8 to Day 12, followed by a 16-day rest starting from Day 13 to Day 28 (1 treatment cycle). Participants received study medication until any of the discontinuation criteria.
