Study Arms:
- Sitagliptin (Type: EXPERIMENTAL): Participants receive sitagliptin 100 mg once daily plus matching placebo for dapagliflozin 5 mg once daily for 4 weeks followed by sitagliptin 100 mg once daily plus matching placebo for dapagliflozin 10 mg once daily for 20 weeks. Participants continue pre-study metformin (at least 1500 mg daily) alone or in combination with a sulfonylurea agent (at a dose of ≥ 50% maximum labeled dose in the country of the investigational site) throughout the duration of the study.
- Dapagliflozin (Type: ACTIVE_COMPARATOR): Participants receive dapagliflozin 5 mg once daily plus matching placebo for sitagliptin 100 mg once daily for 4 weeks followed by dapagliflozin 10 mg once daily plus matching placebo for sitagliptin 100 mg once daily for 20 weeks. Participants continue pre-study metformin (at least 1500 mg daily) alone or in combination with a sulfonylurea agent (at a dose of ≥ 50% maximum labeled dose in the country of the investigational site) throughout the duration of the study.
