What was measured

Overall survival defined as the observed time elapsed between the date of randomization and the date of death due to any cause. The primary estimand of interest was defined to assess the effect of the randomized treatments on the survival duration in all participants regardless of whether or not intercurrent events had occurred (treatment policy strategy). Analysis was performed using Kaplan- Meier method.

Analysis population: Analysis was performed on FAS population.

Groups in this outcome

Trifluridine/Tipiracil + Bevacizumab

Participants were administered 35 mg/m²/dose FTD/TPI orally BID, within 1 hour after completion of morning and evening meals, 5 days on (Day 1 to 5 and Day 8 to 12) with 2 days off (Day 6 to 7 and Day 13 to 14), over 2 weeks, followed by a 14-day rest; with bevacizumab 5 mg/kg, IV infusion administered every 2 weeks (Day 1 and Day 15). This treatment cycle was repeated every 4 weeks.

Trifluridine/Tipiracil

Participants were administered 35 mg/m²/dose of FTD/TPI orally BID, within 1 hour after completion of morning and evening meals, 5 days on (Day 1 to 5 and Day 8 to 12) with 2 days off (Day 6 to 7 and Day 13 to 14), over 2 weeks, followed by a 14-day rest. This treatment cycle was repeated every 4 weeks.
