Brief Summary:
This is a non-inferiority study comparing omarigliptin with sitagliptin in participants with type 2 diabetes mellitus (T2DM) with inadequate glycemic control on metformin therapy. The primary hypothesis is that after 24 weeks, the mean change from baseline in hemoglobin A1c (A1C) in participants treated with omarigliptin is non-inferior to that in participants treated with sitagliptin. There will be a 2-week run-in period with placebo + metformin prior to the double-blind treatment period.

Experimental: Omarigliptin 25 mg once weekly
Participants receive omarigliptin 25 mg once a week plus placebo to sitagliptin once daily for 24 weeks. Participants continue pre-study stable dose of metformin (total daily dose ≥1500 mg) throughout the study. Participants may receive glimepiride (total daily dose of 1-6 mg) as rescue therapy.

Primary Outcome Measures :
- Change From Baseline in A1C at Week 24 [ Time Frame: Baseline and Week 24 ]A1C is a measure of the percentage of glycated hemoglobin in the blood. Participant whole blood samples were collected at baseline and Week 24 to determine the least squares mean A1C change from baseline.
- Percentage of Participants Who Experienced at Least One Adverse Event [ Time Frame: Up to 27 weeks (including 3-week follow-up) ]An adverse event is defined as any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event. Data presented below excludes data after initiation of glycemic rescue therapy.
- Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event [ Time Frame: Up to 24 weeks ]An adverse event is defined as any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event. Data presented below excludes data after initiation of glycemic rescue therapy.
Secondary Outcome Measures :
- Change From Baseline in FPG at Week 24 [ Time Frame: Baseline and Week 24 ]Participant whole blood samples were collected after an overnight fast at baseline and Week 24 to determine the least squares mean change from baseline in participant FPG.
- Percentage of Participants Achieving an A1C Goal <7.0% After 24 Weeks of Treatment [ Time Frame: Week 24 ]Participant whole blood samples were collected at Week 24 to determine the number of participants achieving A1C <7.0% at Week 24.
- Percentage of Participants Achieving an A1C Goal <6.5% After 24 Weeks of Treatment [ Time Frame: Week 24 ]Participant whole blood samples were collected at Week 24 to determine the percentage of participants achieving A1C <6.5% at Week 24.
