  • Change From Baseline in A1C at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
    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) ] [ Designated as safety issue: Yes ]
    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 ] [ Designated as safety issue: Yes ]
    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.
  • Change From Baseline in A1C at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
  • Number of participants who experienced at least one adverse event [ Time Frame: Up to Week 27 ] [ Designated as safety issue: Yes ]
  • Number of participants who discontinued from the study due to an adverse event [ Time Frame: Up to Week 27 ] [ Designated as safety issue: Yes ]

  • Change From Baseline in FPG at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    Participant whole blood samples were collected at Week 24 to determine the percentage of participants achieving A1C <6.5% at Week 24.
  • Change from baseline in fasting plasma glucose (FPG) at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
  • Number of participants achieving an A1C goal <7.0% and < 6.5% after 24 weeks of treatment [ Time Frame: Week 24 ] [ Designated as safety issue: No ]

Study to Evaluate the Safety and Efficacy of the Addition of Omarigliptin (MK-3102) Compared With the Addition of Sitagliptin in Participants With Type 2 Diabetes Mellitus With Inadequate Glycemic Control on Metformin (MK-3102-026)
A Phase III, Multicenter, Double-Blind, Randomized Study to Evaluate the Safety and Efficacy of the Addition of MK-3102 Compared With the Addition of Sitagliptin in Subjects With Type 2 Diabetes Mellitus With Inadequate Glycemic Control on Metformin
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.
