addition of omarigliptin (mk-3102) to participants with type 2 diabetes mellitus who have inadequate glycemic control on combination therapy with glimepiride and metformin (mk-3102-022)

Conditions: Type 2 Diabetes Mellitus

Summary: this study will examine the safety and efficacy of the addition of omarigliptin in participants with type 2 diabetes mellitus with inadequate glycemic control on metformin and glimepiride. the primary hypothesis is that after 24 weeks, the addition of treatment with omarigliptin provides a greater reduction in hemoglobin a1c (a1c) compared with the addition of placebo.
