Last verified: August 2014
  Purpose

The purpose of this study is to assess the safety and efficacy of MK-3102, dosed once-weekly in participants with T2DM who have inadequate glycemic control on diet and exercise. The primary hypothesis is that after 24 weeks, treatment with MK-3102 compared with placebo provides greater reduction in hemoglobin A1c (A1C).

Primary Outcome Measures:
  • Change from baseline in hemoglobin A1c (A1C) at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
  • Percentage of participants who experienced at least one adverse event [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: Yes ]
  • Percentage of participants who discontinued from the study due to an adverse event [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: Yes ]
  • Percentage of participants who experienced at least one adverse event [ Time Frame: Up to 57 weeks ] [ Designated as safety issue: Yes ]
  • Percentage of participants who discontinued from the study due to an adverse event [ Time Frame: Up to 54 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Change from baseline in fasting plasma glucose (FPG) at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
  • Percentage of participants who achieve an A1C goal of <7% (53 mmol/mol) at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
  • Percentage of participants who achieve an A1C goal of <7% at Week 54 [ Time Frame: Baseline and Week 54 ] [ Designated as safety issue: No ]
  • Change from baseline in 2-hour post meal glucose (PMG) at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
  • Change from baseline in A1C at Week 54 [ Time Frame: Baseline and Week 54 ] [ Designated as safety issue: No ]
  • Change from baseline in FPG at Week 54 [ Time Frame: Baseline and Week 54 ] [ Designated as safety issue: No ]
  • Percentage of participants who achieve an A1C goal of <6.5% (48 mmol/mol) at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
  • Percentage of participants who achieve an A1C goal of <6.5% at Week 54 [ Time Frame: Baseline and Week 54 ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: MK-3102
MK-3102 25 mg capsule administered orally once a week for 24 weeks (Phase A) followed by MK-3102 25 mg administered orally plus placebo to metformin (Phase B). Open-label metformin may be initiated as glycemic rescue therapy in Phase A, and open-label glimepiride in Phase B.
Drug: MK-3102
MK-3102 25 mg capsule administered orally once a week.
Drug: Metformin
If necessary, participants may have glycemic rescue therapy initiated with open-label metformin during Phase A of the study. Participants in the placebo treatment group who were not rescued with open-label metformin during Phase A will receive blinded metformin (starting at 500 mg orally twice daily with up-titration to 1000 mg orally twice daily) in Phase B. Participants in the MK-3102 treatment group who were rescued with open-label metformin in Phase A will continue open-label metformin during Phase B of the study.

  • Glumetza®
  • Riomet®
  • Metgluco®
  • Glycoran®
Drug: Placebo to metformin
During Phase B of the study, participants in the MK-3102 treatment group who did not initiate glycemic rescue therapy during Phase A will receive placebo to metformin for 30 weeks (Phase B of the study).
Drug: Glimepiride
If necessary during Phase B of the study, participants will initiate open-label glimepiride as glycemic therapy
Other Name: Armaryl®
Placebo Comparator: Placebo to MK-3102
Placebo to MK-3102 administered orally once a week for 24 weeks (Phase A) followed by placebo to MK-3102 administered orally once a week plus metformin for an additional 30 weeks (Phase B).
