    5. Study Description

    Brief Summary
    The purpose of this study is to assess the effect of the addition of sitagliptin (administered as MK-0431A or MK-0431A XR) relative to the addition of placebo on glycated hemoglobin (A1C), and the safety and tolerability of the addition of sitagliptin, in pediatric participants (ages 10-17 years) with type 2 diabetes mellitus with inadequate glycemic control on metformin therapy (alone or in combination with insulin). The primary hypothesis is that the addition of sitagliptin reduces glycated hemoglobin (A1C) more than the addition of placebo after 20 weeks of treatment.
