Ertugliflozin 5 mg orally (1 ertugliflozin 5 mg tablet and 1 placebo ertugliflozin 10 mg tablet), once daily from Day 1 to Week 104.

Ertugliflozin 15 mg orally (1 ertugliflozin 5 mg tablet and 1 ertugliflozin 10 mg tablet), once daily from Day 1 to Week 104.

Placebo to ertuglioflozin (1 placebo ertugliflozin 5 mg tablet and/or 1 placebo ertugliflozin 10 mg tablet), orally once daily from Day 1 to Week 104.

Open-label Glimepiride will be used for glycemic rescue therapy (up to a maximum of 6 or 8 mg per day, based on the local label of glimepiride) in the 26-week initial period. Blinded Glimepiride (up to a maximum of 6 or 8 mg per day, based on the local label of glimepiride will be used in the 78-week extension period in participants who were not rescued with open-label glimepiride during the 26-week initial period.

Placebo to glimepiride will be used in the 78-week extension period in participants who were not rescued with open-label glimepiride during the 26-week initial period. Dosing and titration of placebo to glimepiride is at the discretion of the investigator.

Basal insulin will be administered in the initial 26-week period for participants with glucose values exceeding protocol-specified values and for participants requiring rescue therapy in the 78-week extension period. Dosing and titration of basal insulin is at the discretion of the Investigator.
