Summary
The purpose of the study is to assess the safety of the addition of sitagliptin, and its effect on hemoglobin A1c (A1C) in pediatric participants 10-17 years of age with type 2 diabetes mellitus (T2DM) with inadequate glycemic control. The primary hypothesis for this study is that sitagliptin reduces A1C more than placebo after 20 weeks of treatment.Phase:

to the Screening Visit/Visit 1, or is on a stable dose of insulin (without any other
AHA) for at least 12 weeks prior to the Screening Visit/Visit 1. At screening,
participants on insulin doses that are not stable can have their insulin doses
adjusted and be eligible to participate after their dose remains stable for ≥12 weeks,
if they meet all other eligibility criteria. In India, only participants on stable
doses of insulin will be eligible.
- An A1C of ≥6.5% and ≤10.0% (For participants on insulin: an A1C ≥7.0% and ≤10.0%).
Exclusion Criteria:
- History of type 1 diabetes mellitus, autoimmune diabetes mellitus or has a positive
antibody screen for anti-GAD (Glutamic Acid Decarboxylase) or (Islet cell autoantigen)
ICA-512.
- Known monogenic diabetes, secondary diabetes, or a genetic syndrome or disorder known
to affect glucose tolerance other than diabetes.

ketonemia requiring immediate initiation of antihyperglycemic therapy.
- Previously taken a DPP-4 (Dipeptidyl peptidase-4) inhibitor (such as sitagliptin,
vildagliptin, alogliptin, or saxagliptin) or GLP-1 (Glucagon-like peptide-1) receptor
agonist (such as exenatide or liraglutide).
