Study consisted of an open-label, safety run-in part and a randomized, double-blind, placebo-controlled Phase 2/3 part. In the Phase 2/3 part, the study was evaluated whether bintrafusp alfa in combination with the current standard of care (SoC) (gemcitabine plus cisplatin) improves overall survival (OS) in chemotherapy and immunotherapy-naïve participants with locally advanced or metastatic Biliary Tract Cancer (BTC) compared to placebo, gemcitabine and cisplatin.
Participants received intravenous infusion of M7824 at a dose of 2400 milligrams (mg), once every 3 weeks (Q3W) 2 years (in case of Complete Response), otherwise until criterion pre-sepcified in protocol for discontinuation is met, in combination with intravenous infusion of Gemcitabine and Cisplatin at a dose of 1000 milligram per meter square (mg/m\^2) and 25 mg/m\^2 respectively on Day 1 and Day 8 of 21- day cycle, for 8 cycles every 3 weeks.
Participants received intravenous infusion of M7824 matched placebo, once every 3 weeks (Q3W) until 2 years (in case of CR), otherwise until crtiterion pre-sepcified in protocol for discontinuation is met.
Gemcitabine was received intravenously at a dose of 1000 milligram per meter square (mg/m\^2) on Day 1 and Day 8 of 21- day cycle, for 8 cycles every 3 weeks (Q3W).
Cisplatin was received intravenously at a dose of 25 mg/m\^2 on Day 1 and Day 8 of 21-day cycle, for 8 cycles every 3 weeks (Q3W).
