Study Arms:
- Pembrolizumab + SOC (Type: EXPERIMENTAL): Participants receive pembrolizumab 200 mg intravenously (IV) every 3 weeks (Q3W) plus standard of care (SOC) chemotherapy with cisplatin 80 mg/m\^2 IV Q3W and 5-FU 800 mg/m\^2/day continuous IV infusion on Days 1 to 5 (120 hours) Q3W. All treatments will be administered on an outpatient basis beginning on Day 1 of each 3-week dosing cycle.
- Placebo + SOC (Type: PLACEBO_COMPARATOR): Participants receive placebo to pembrolizumab (saline) IV Q3W plus SOC chemotherapy with cisplatin 80 mg/m\^2 IV Q3W and 5-FU 800 mg/m\^2/day continuous IV infusion on Days 1 to 5 (120 hours) Q3W. All treatments will be administered on an outpatient basis beginning on Day 1 of each 3-week dosing cycle.
