A Study of the Safety and Efficacy of Sitagliptin Addition During Metformin Up-titration (MK-0431-848)

Summary

This trial is designed to evaluate, in adult participants with Type 2 diabetes mellitus (T2DM) and inadequate glycemic control on sub-maximal metformin mono-therapy (1000 mg/day), the effect of up-titration of metformin plus the addition of sitagliptin compared to up-titration of metformin alone on glycemic control. The primary hypothesis of this study is that up-titration of metformin to 2000 mg/day (1000 mg/twice a day) plus the addition of sitagliptin 100 mg/day provides greater reduction in hemoglobin A1C (A1C) compared to metformin up-titration alone. Another primary objective of this study is to evaluate the safety and tolerability of this treatment.
