A Study of the Efficacy and Safety of MK-0431D (a Fixed-dose Combination of Sitagliptin and Simvastatin) for the Treatment of Participants With Type 2 Diabetes Mellitus (T2DM) With Inadequate Glycemic Control on Metformin Monotherapy (MK-0431D-266)

Summary

The purpose of this study is to assess the efficacy and safety of sitagliptin/simvastatin fixed-dose combination (FDC) in participants with T2DM who have inadequate glycemic control while on metformin monotherapy.
