NCT01755156

Brief Summary

The purpose of this study is to assess the safety and efficacy of omarigliptin compared to placebo in participants with inadequate glycemic control on metformin monotherapy. The primary hypothesis is that after 24 weeks, the addition of treatment with omarigliptin provides greater reduction in hemoglobin A1c (A1C) than placebo.

Outcome Measures

Primary Outcomes (4)

  • Change From Baseline in Glycosylated Hemoglobin (A1C) at Week 24 (Phase A)

    A1C is measured as a percent. Change from baseline in A1C at Week 24 was analyzed using a constrained longitudinal data analysis (cLDA) method with a restriction of the same baseline mean across treatment groups. The cLDA model included terms for treatment, time, and the interaction of time by treatment.

    Baseline and Week 24

  • Percentage of Participants Who Experienced at Least One Adverse Event (Phase A+B)

    An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. Presented data exclude data after glycemic rescue.

    Up to 107 weeks

  • Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event (Phase A+B)

    An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. Presented data exclude data after glycemic rescue.

    Up to 104 weeks

  • Percentage of Participants Who Experienced an Adverse Event Which Were Included Under the System Order Class of Investigations (Phase A+B)

    The following laboratory parameters were included: blood chemistry, hematology, electrocardiograms, lipids, body weight, and vital signs.

    Up to 104 weeks

Secondary Outcomes (15)

  • Change From Baseline in 2-hour Post-meal Glucose (PMG) at Week 24 (Phase A)

    Baseline and Week 24

  • Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 (Phase A)

    Baseline and Week 24

  • Change From Baseline in A1C at Week 104 (Phase A+B)

    Baseline and Week 104

  • Change From Baseline in FPG at Week 104 (Phase A+B)

    Baseline and Week 104

  • Percentage of Participants Attaining A1C Glycemic Goals of <7.0% After 24 Weeks of Treatment (Phase A)

    24 weeks

  • +10 more secondary outcomes

Study Arms (2)

Omarigliptin (Phase A) → Omarigliptin (Phase B)

EXPERIMENTAL

Phase A: Omarigliptin 25 mg capsule administered orally once weekly for 24 weeks. Phase B: Omarigliptin 25 mg capsule administered orally once weekly and matching placebo to glimepiride tablet/capsule administered orally once daily for 80 weeks. Participants will continue pre-study metformin throughout the duration of the study. If necessary, rescue therapy may be initiated (open-label glimepiride during Phase A and insulin glargine during Phase B).

Drug: OmarigliptinDrug: Matching placebo to glimepirideDrug: Insulin glargineDrug: Metformin

Placebo to omarigliptin (Phase A) → Glimepiride (Phase B)

PLACEBO COMPARATOR

Phase A: matching placebo to omarigliptin orally once a week for 24 weeks. Phase B: Matching placebo to omarigliptin capsule administered orally once weekly and glimepiride 1 or 2 mg tablet/capsule administered orally once daily (titrated up to 6 mg daily) for 80 weeks. Participants will continue pre-study metformin throughout the duration of the study. If necessary, rescue therapy may be initiated (open-label glimepiride during Phase A and insulin glargine during Phase B).

Matching placebo to omarigliptin capsule administered orally once weekly (preferably on the same day of each week)

Placebo to omarigliptin (Phase A) → Glimepiride (Phase B)

Glimepiride 1 or 2 mg tablet/capsule administered orally once daily and up-titrated to a maximum dose of 6 mg daily. Participants rescued with open-label glimepiride during Phase A will not receive glimepiride or matching placebo to glimepiride during Phase B.

Also known as: Amaryl®
Placebo to omarigliptin (Phase A) → Glimepiride (Phase B)

Matching placebo to glimepiride tablet/capsule administered orally once daily and up-titrated to a mock maximum dose of 6 mg daily. Participants rescued with open-label glimepiride during Phase A will not receive glimepiride or matching placebo to glimepiride during Phase B.

Omarigliptin (Phase A) → Omarigliptin (Phase B)

During Phase B of the study, participants who received a maximum up-titration of open-label glimepiride or blinded glimepiride/matching placebo to glimepiride, may be rescued with open-label insulin glargine.
