Primary outcomePrimary: Change From Baseline in Hemoglobin A1C (HbA1C) Levels at Week 24 in Participants Receiving Insulin Alone or in Combination With Metformin — -0.67; -0.32 A1C % — p=<0.001
Summary
A study to compare safety and efficacy of sitagliptin and placebo therapy when added to stable insulin alone or in combination with metformin in participants with type 2 diabetes mellitus (T2DM). The primary hypothesis of this study is that after 24 weeks, the addition of sitagliptin compared with placebo provides greater reduction in hemoglobin A1C (HbA1C) in T2DM participants on insulin alone or in combination with metformin.
