NCT01703221

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.

Outcome Measures

Primary Outcomes (5)

  • Change From Baseline for Hemoglobin A1c (HbA1c) at 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).

    Baseline and Week 24

  • Percentage of Participants Who Experienced at Least One Adverse Event During Phase A

    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.

    Up to 24 weeks

  • Percentage of Participants Who Experienced at Least One Adverse Event During the Overall Study

    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.

    Up to 52 weeks

  • Percentage of Participants Who Discontinued From the Study Due to an Adverse Event During Phase A

    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.

    Up to 24 weeks

  • Percentage of Participants Who Discontinued From the Study Due to an Adverse Event During the Overall Study

    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.

    Up to 52 weeks

Secondary Outcomes (2)

  • Change From Baseline for 2-hour Post Meal Glucose (PMG) at Week 24
