A Phase III, Multicenter, Double-Blind, Randomized, Placebo-Controlled Clinical Trial to Evaluate the Safety and Efficacy of Sitagliptin in Pediatric Patients With Type 2 Diabetes Mellitus With Inadequate Glycemic Control

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.

This trial is of approximately 56 weeks in duration, including a screening period of up to 1
week, a 1-week single-blind placebo run-in period, a 20-week placebo-controlled, double blind
treatment period [Phase A] and a 34-week double-blind active controlled treatment period
[Phase B] during which participants randomized to the placebo arm who have not initiated
glycemic rescue therapy with metformin during Phase A will receive metformin (in a blinded
manner). A telephone contact will be performed 14 days after the last dose of study
medication to assess for any serious adverse events (SAEs).

Two arms of the study were removed from the study by a protocol amendment.

Inclusion Criteria:

- Type 2 Diabetes Mellitus (T2DM)

- Has not received treatment with an antihyperglycemic agent (AHA) for ≥12 weeks prior
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.

- Symptomatic hyperglycemia and/or moderate to large ketonuria and/or positive test for
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).

- Hypersensitivity or contraindication (according to the product circular in the country
of the investigational site) to metformin.

- Chronic treatment with a medication known to cause weight gain within 30 days of study
start or weight loss or increased blood glucose within 8 weeks of study start or
treated with an anti-psychotic within the past 12 weeks.

- On a weight loss program and not in the maintenance phase or have undergone bariatric
surgery within 12 months prior to study start.

- On or likely to require treatment with ≥14 consecutive days or repeated courses of
pharmacologic doses of corticosteroids.

- Undergone a surgical procedure within the prior 4 weeks or has major surgery planned
during the study.

- History of congenital heart disease or cardiovascular disease other than hypertension.

- Medical history of active liver disease (other than non-alcoholic hepatic steatosis),
including chronic active hepatitis B or C, primary biliary cirrhosis, or symptomatic
gallbladder disease.

- Active nephropathy (i.e., nephrotic syndrome or glomerulonephritis).

- Chronic myopathy, mitochondrial disorder, or a progressive neurological or
neuromuscular disorder (e.g., polymyositis, or multiple sclerosis).

- Human immunodeficiency virus (HIV) as assessed by medical history.

- Clinically significant hematological disorder (such as aplastic anemia,
thrombocytopenia, myeloproliferative or myelodysplastic syndrome).

- Under treatment for hyperthyroidism.

- Exhibits abnormal growth patterns or is being treated with growth hormone.

- History of malignancy or clinically important hematologic disorder.

- History of idiopathic acute pancreatitis or chronic pancreatitis.

- Known history of recreational or illicit drug use, or of alcohol abuse or dependence
(within the past year).

- Donated blood products or has had phlebotomy of >10% of estimated total blood volume
within 8 weeks of signing informed consent, or intends to donate blood products or
receive blood products within the projected duration of the study.

- Pregnant, has a positive urine pregnancy test at Screening Visit/Visit 1, is expecting
to conceive within the projected duration of the study, or is breast-feeding.

- Exclusionary laboratory values.
