Study Description

Brief Summary:
The purpose of this study is to assess the efficacy of omarigliptin 25 mg weekly (as monotherapy) compared with sitagliptin 50 mg daily and placebo, and the long term safety (up to 52 weeks) of omarigliptin 25 mg weekly. The primary hypotheses are that after 24 weeks: 1) Omarigliptin 25 mg weekly provides a greater reduction from baseline in glycosylated hemoglobin (HbA1c) compared with placebo, and 2) The mean change from baseline in HbA1c in participants treated with omarigliptin 25 mg weekly is non-inferior compared with that in participants treated with sitagliptin 50 mg daily.

Condition or disease Intervention/treatment Phase
Type 2 Diabetes Mellitus Drug: Omarigliptin Drug: Sitagliptin Drug: Placebo to omarigliptin Drug: Placebo to sitagliptin Phase 3

Detailed Description:
The treatment period is composed of a 24-week double-blind period (Phase A) and a 28-week open-label period (Phase B). Participants will receive in Phase A: omarigliptin 25 mg once weekly, sitagliptin 50 mg once daily or placebo and in Phase B: omarigliptin 25 mg once weekly.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change From Baseline for Hemoglobin A1c (HbA1c) at Week 24 [ Time Frame: Baseline and Week 24 ]
    HbA1C is blood marker used to report average blood glucose levels over prolonged periods of time and is reported as a percentage (%). Change in A1C following 24 weeks of therapy (i.e., A1C at Week 24 minus A1C at baseline).

  2. Percentage of Participants Who Experienced at Least One Adverse Event During Phase A [ Time Frame: Up to 24 weeks ]
    An adverse event (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, that occurs during the course of the study.

  3. Percentage of Participants Who Experienced at Least One Adverse Event During the Overall Study [ Time Frame: Up to 52 weeks ]
    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, that occurs during the course of the study. These results represent the accrual of events over different treatment intervals: 52 weeks, omarigliptin (Phase A+B) defined as the double-blind period and open label extension period versus 28 weeks for the Sitagliptin (Phase A)→Omarigliptin (Phase B) and placebo (Phase A)→Omarigliptin (Phase B) group defined as the open-label extension period only.

  4. Percentage of Participants Who Discontinued From the Study Due to an Adverse Event During Phase A [ Time Frame: Up to 24 weeks ]
    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, that occurs during the course of the study.

  5. Percentage of Participants Who Discontinued From the Study Due to an Adverse Event During the Overall Study [ Time Frame: Up to 52 weeks ]
    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, that occurs during the course of the study. These results represent the accrual of events over different treatment intervals: 52 weeks, omarigliptin (Phase A+B) defined as the double-blind period and open label extension period versus 28 weeks for the Sitagliptin (Phase A)→Omarigliptin (Phase B) and placebo (Phase A)→Omarigliptin (Phase B) group defined as the open-label extension period only.


Secondary Outcome Measures :
  1. Change From Baseline for 2-hour Post Meal Glucose (PMG) at Week 24 [ Time Frame: Baseline and Week 24 ]
    Change from baseline at Week 24 is defined as PMG at Week 24 minus PMG at Week 0.

  2. Change From Baseline for Fasting Plasma Glucose (FPG) at Week 24 [ Time Frame: Baseline and Week 24 ]
    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).
