What was measured

PFS was defined as the time elapsed between the date of randomisation and the date of radiological tumour progression as per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) assessed by investigator, or death (from any cause), whichever comes first. Progressive Disease (PD) as per RECIST 1.1: at least a 20 percent (%) increase in sum of diameters of target lesions, unequivocal progression of existing non-target lesions. Analysis was performed by Kaplan-Meier method. In this outcome measure, data of PFS at 3 months was reported.

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.
