  Purpose
The purpose of this study is to assess the hypothesis that treatment with study medication (omarigliptin; MK-3102) provides greater reduction in A1C Hemoglobin (a marker of diabetic severity) compared with placebo, after 12 weeks of treatment. The study will evaluate 5 different doses of omarigliptin to identify which dose is the most effective in the treatment of type 2 diabetes.

Primary Outcome Measures:
  • Change From Baseline in Plasma A1C Levels at Week 12 [ Time Frame: Baseline (Week 0) and Week 12 ]
    A1C levels were measured as a percent. Change from baseline was calculated by subtracting the baseline level from the Week 12 level.

  • Percentage of Participants Who Experienced at Least One Adverse Event During the Base Period [ Time Frame: Up to 16 weeks (including 28 days following the last dose of study drug) ]
    An adverse event is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition which is temporally associated with the use of the Sponsor's product, is also an adverse event. Data presented below excludes data after the initiation of glycemic rescue.

  • Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event During the 12-week Base Period [ Time Frame: Up to 12 weeks ]
    An adverse event is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition which is temporally associated with the use of the Sponsor's product, is also an adverse event. Data presented below excludes data after the initiation of glycemic rescue.

  • Percentage of Participants Who Experienced at Least One Adverse Event During the 66-week Extension Period [ Time Frame: Up to 70 Weeks (Weeks 12 to 78 plus 4-week follow-up period) ]
    An adverse event is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the Sponsor's product, is also an adverse event. Data presented below excludes data after the initiation of glycemic rescue.

  • Percentage of Participants Who Discontinued From Study Drug Due to an Adverse Event During the 66-week Extension Period [ Time Frame: Up to 66 weeks (Weeks 12 to 78) ]
    An adverse event is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the Sponsor's product, is also an adverse event. Data presented below excludes data after the initiation of glycemic rescue.


Secondary Outcome Measures:
  • Change From Baseline in 2 Hour-post-meal Glucose (2h-PMG) Levels at Week 12 [ Time Frame: Baseline (Week 0) and Week 12 ]
    Change from baseline was calculated by subtracting the baseline level from the Week 12 level.

  • Change From Baseline in Fasting Plasma Glucose (FPG) Levels at Week 12 [ Time Frame: Baseline (Week 0) and Week 12 ]
    Change from baseline was calculated by subtracting the baseline level from the Week 12 level.

  • Mean Plasma A1C Level at Baseline of the Extension Period [ Time Frame: Baseline (Week 0) ]
    A1C levels were measured as a percent at baseline (Week 0) for participants who entered the extension period.

  • Change From Baseline in Plasma A1C Levels at Week 78 [ Time Frame: Baseline (Week 0) and Week 78 ]
    A1C levels were measured as a percent. Change from baseline was calculated by subtracting the baseline level from the Week 78 level.

  • Mean 2h-PMG Level at Baseline of the Extension Period [ Time Frame: Baseline (Week 0) ]
    Plasma 2h-PMG levels were measured at baseline (Week 0) for participants who entered the extension period.

  • Change From Baseline in 2h-PMG at Week 78 [ Time Frame: Baseline (Week 0) and Week 78 ]
    Change from baseline was calculated by subtracting the baseline level from the Week 78 level.

  • Mean FPG Level at Baseline of the Extension Period [ Time Frame: Baseline (Week 0) ]
    Plasma FPG levels were measured at baseline (Week 0) for particiapnts who entered the extension period.

  • Change From Baseline in FPG Levels at Week 78 [ Time Frame: Baseline (Week 0) and Week 78 ]
    Change from baseline was calculated by subtracting the baseline level from the Week 78 level.

Detailed Description:
MK-3102-006-Ext 1 added a 66-week extension to the base study (MK-3102 P006) to assess the long-term safety and tolerability of omarigliptin. To be eligible for the extension, participants must complete the double-blind base study, must have had at least a 75% compliance with study drug during the base study and can not meet any of the criteria for discontinuation. Participants randomized to placebo in the base study will be switched in a blinded manner to pioglitazone 30 mg once daily, in the extension study prior to implementation of amendment P006-13. Once amendment P006-13 has been IRB/IEC approved and blinded metformin drug supply is available at the site, participants will be switched from pioglitazone to metformin, starting at 500 mg once daily and titrated up to 1000 mg twice daily. Participants with a contraindication to metformin will be discontinued from the study. Participants randomized to 0.25 mg, 1 mg, 3 mg, and 10 mg of omarigliptin in the base study will be switched to omarigliptin 25 mg; those randomized to 25 mg of omarigliptin in the base study will continue on the same dose in the extension study. After the clinical dose of omarigliptin selected for further development has been identified based upon the results of the base study, all participants randomized to omarigliptin will be switched to the identified clinical dose.
