A Study to Evaluate the Safety and Efficacy of Omarigliptin (MK-3102) Compared With Glimepiride in Participants With Type 2 Diabetes Mellitus for Whom Metformin is Inappropriate (MK-3102-027)

A Phase III, Multicenter, Double-Blind, Randomized Trial to Evaluate the Safety and Efficacy of MK-3102 Compared With Glimepiride in Subjects With Type 2 Diabetes Mellitus For Whom Metformin is Inappropriate Due to Intolerance or Contraindication

This trial will assess the safety and efficacy of omarigliptin (MK-3102) compared with the sulfonylurea, glimepiride, in type 2 diabetes mellitus participants who are metformin intolerant or who have a contraindication to the use of metformin. The primary hypothesis is that after 54 weeks, the mean change from baseline in hemoglobin A1c (A1C) in participants treated with omarigliptin is non-inferior compared with that in participants treated with glimepiride.

Inclusion Criteria:

• Diagnosed with type 2 diabetes mellitus
• Have intolerability to metformin ≥1000 mg/day or have a contraindication to the use of metformin
• Females of reproductive potential agree to remain abstinent or use or have their partner use 2 acceptable methods of birth control

Exclusion Criteria:

• History of type 1 diabetes mellitus or a history of ketoacidosis or assessed by the investigator as possibly having type 1 diabetes

• Has been treated with:

  1. A thiazolidinedione (TZD) within 4 months of study participation, or
  2. A glucagon-like peptide-1 (GLP-1) receptor mimetic or agonist (such as exenatide or liraglutide) within 6 months of study participation, or
  3. Insulin within 12 weeks prior to study participation, or
  4. Dual antihyperglycemic agent (AHA) therapy within 12 weeks of study participation (4 months if a component of the dual AHA therapy was a TZD)
  5. Omarigliptin (MK-3102) at any time prior to study participation

• On a weight loss program and is not in the maintenance phase; has started a weight loss medication in the past 6 months; or has undergone bariatric surgery within 12 months prior to study participation
