NCT00767000

Brief Summary

The purpose of this study is to test the effect of MK-0941 as add-on therapy for participants taking insulin for type 2 diabetes mellitus. The primary hypotheses of this study are that treatment with MK-0941 added to insulin will provide greater reduction in hemoglobin A1c (HbA1c) level than will placebo added to insulin at 14 weeks, and that MK-0941 will be well-tolerated at 1 or more doses that demonstrate efficacy.

Outcome Measures

Primary Outcomes (3)

  • Change in Hemoglobin A1c (HbA1c) Level

    Least square means change from baseline in HbA1c. HbA1c represents the percentage of glycated hemoglobin. A negative number means reduction in HbA1c level.

    Baseline and Weeks 14, 54, 106, and 158

  • Percentage of Participants Who Experienced at Least One Adverse Event

    Entire study including 54-week study and 104-week extension

  • Percentage of Participants Who Discontinued Study Medication Due to an Adverse Event

    Entire study including 54-week study and 104-week extension

Secondary Outcomes (4)

  • Change in the Two-hour Post Meal Glucose Level

    Baseline and Weeks 14, 54, 106, and 158

  • Change in the Fasting Plasma Glucose Level

    Baseline and Weeks 14, 54, 106, and 158

  • Percentage of Participants Who Achieve an HbA1c of <7.0%

    Weeks 106 and 158

  • Percentage of Participants Achieving an HbA1c of <7.0% at Week 54 Who Maintain an HbA1c of <7.0%

    Weeks 54, 106 and 158
