Experimental: Chemotherapy + Best Supportive Care (BSC) - In Maintenance Phase, participants continued the same regimen of oxaliplatin-fluoropyrimidine doublet chemotherapy (oxaliplatin + 5FU/LV or oxaliplatin + capecitabine) as they received during the Induction Phase until disease progression, significant clinical deterioration, unacceptable toxicity, or discontinuation. Participants who were not deemed eligible to receive chemotherapy at the dose and schedule specified above received BSC alone once every 3 weeks. BSC was defined as treatment administered with the intent to maximize quality of life without a specific antineoplastic regimen and was based on Investigator's discretion.

Experimental: Avelumab - In Maintenance phase, participants received avelumab as a 1-hour intravenous (IV) infusion at 10 milligrams per kilogram (mg/kg) once every 2-week treatment cycle until progressive disease or unacceptable toxicity or discontinuation.


Treatment: Drugs: Avelumab
Maintenance Phase: Intravenous (IV) infusion (10 mg/kg over 1 hour) once every 2 weeks.

Treatment: Drugs: Oxaliplatin
Induction Phase: Oxaliplatin was administered at a dose of 85 mg per square meter (mg/m\^2) as a continuous intravenous (IV) infusion on Day 1 along with leucovorin followed by 5-Fluorouracil every 2 weeks up to 12 weeks (or) Oxaliplatin at 130 mg/m\^2 IV on Day 1 along with capecitabine twice daily for 2 weeks followed by a 1-week rest period given every 3 weeks up to 12 weeks.

Maintenance Phase: Participants were continued the same regimen of chemotherapy as they received during the Induction Phase until disease progression, significant clinical deterioration, unacceptable toxicity, or discontinuation.

Treatment: Drugs: 5-Fluorouracil
Induction Phase: 5-Fluorouracil was administered at a dose of 2600 mg/m\^2 IV continuous infusion over 24 hours on Day 1 (or) 5-FU at 400 mg/m\^2 IV push on Day 1 and 2400 mg/m\^2 IV continuous infusion over 46-48 hours (Days 1 and 2) along with oxaliplatin and leucovorin every 2 weeks up to 12 weeks. Maintenance Phase: Participants were continued the same regimen of chemotherapy as they received during the Induction Phase until disease progression, significant clinical deterioration, unacceptable toxicity, or discontinuation.

Treatment: Drugs: Leucovorin
Induction Phase: Leucovorin was administered at a dose of 200 mg/m\^2 IV (or) Leucovorin 400 mg/m\^2 IV on Day 1 along with oxaliplatin and 5-FU every 2 weeks up to 12 weeks.

Maintenance Phase: Participants were continued the same regimen of chemotherapy as they received during the Induction Phase until disease progression, significant clinical deterioration, unacceptable toxicity, or discontinuation.

Treatment: Drugs: Capecitabine
Induction Phase: Capecitabine was administered at a dose of 1000 mg/m\^2 twice daily for 2 weeks followed by a 1-week rest period given every 3 weeks along with oxaliplatin up to 12 weeks.

Maintenance Phase: Participants were continued the same regimen of chemotherapy as they received during the Induction Phase every 3 weeks until disease progression, significant clinical deterioration, unacceptable toxicity, or discontinuation.
