  Purpose
This study will examine the safety and efficacy of the addition of omarigliptin in participants with type 2 diabetes mellitus with inadequate glycemic control on metformin and glimepiride. The primary hypothesis is that after 24 weeks, the addition of treatment with omarigliptin provides a greater reduction in hemoglobin A1c (A1C) compared with the addition of placebo.

Primary Purpose: Treatment
Official Title: A Phase III, Multicenter, Randomized, Double-blind, Placebo-controlled Clinical Trial to Study the Safety and Efficacy of the Addition of MK-3102 to Subjects With Type 2 Diabetes Mellitus Who Have Inadequate Glycemic Control on Combination Therapy With Glimepiride and Metformin

Primary Outcome Measures:
  • Change From Baseline in Hemoglobin A1c (A1C) at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
    A1C is blood marker used to report average blood glucose levels over a prolonged periods of time and is reported as a percentage (%). Thus, this change from baseline reflects the Week 24 A1C minus the Week 0 A1C.

  • Percentage of Participants Who Experienced at Least One Adverse Event (AE) [ Time Frame: Up to Week 27 ] [ Designated as safety issue: Yes ]
    An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure.

  • Percentage of Participants Who Discontinued From the Study Due to an AE [ Time Frame: Up to Week 24 ] [ Designated as safety issue: Yes ]
    An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure.


Secondary Outcome Measures:
  • Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
    Blood glucose was measured on a fasting basis. FPG is expressed as mg/dL. Blood was drawn at predose on Day 1 and after 24 weeks of treatment to determine change in plasma glucose levels (i.e., FPG at Week 24 minus FPG at baseline).

  • Percentage of Participants Attaining A1C Glycemic Goals of <7% and <6.5% at Week 24 [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    The percentage of participants who achieved A1C values <6.5% (48 mmol/mol) or <7.0% (53 mmol/mol) in the FAS population at Week 24.
