- Healthy male or female adolescents, age 12 to 17 years (inclusive) at Screening, with a BMI that is greater than or equal to the United States-weighted mean of the 95th percentile based on age and sex with a body weight greater than 60 kilograms (kg). Participants with Type 2 diabetes mellitus (T2DM) may have a pre-existing or new diagnosis of T2DM.
Participants with pre-existing T2DM should have prior documentation consistent with the diagnosis and/or be on active pharmacotherapy for T2DM.
Participants with a new diagnosis of T2DM (ie, diagnosed at Screening) should be based on the 2016 American Diabetes Association (ADA) guidelines. The diagnostic criteria are met if a participant has unequivocal hyperglycemia (random plasma glucose ≥200 milligrams per deciliter (mg/dL) (11.1 millimoles per liter [mmol/L]) with classic symptoms of hyperglycemia or hyperglycemic crisis) OR any of the following criteria are observed and confirmed:
-
HbA1c ≥6.5%
-
fasting plasma glucose (FPG) ≥126 mg/dL (7.0 mmol/L)
-
2-hour plasma glucose ≥200 mg/dL (11.1 mmol/L) by an oral glucose tolerance test (OGTT) All T2DM participants must have an HbA1c <10% at Screening. If participants are being or need to be treated with antidiabetic agents, the T2DM treatment regimen must be stable for at least 3 months before randomization. A single rescreen is allowed following stabilization. Stable control refers to minimal dose changes to existing medications for glycemic control and no medications being initiated for glycemic control in the 3 months before randomization. Minimal changes are defined as a change without any change in dose frequency, no add-on or discontinuation of other antidiabetic agents and the participant has not been hospitalized due to hypo- or hyperglycemic events.

- Systolic pulmonary artery pressure (SPAP) >40 mmHg (and/or tricuspid regurgitation [TR] jet velocity >2.9 m/s) In cases where an actual SPAP value is not measurable due to lack of adequate TR jet, the pulmonary flow acceleration time measured at the right ventricular outflow tract (RVOTAT) will be used to assess eligibility. Participants with a RVOTAT ≤100 milliseconds (msec) will be excluded, suggesting an elevated mean SPAP; eligibility for the those participants with RVOTAT between 100 and 120 msec will be determined based on combined assessment of the TR jet, septal motion, and right ventricular size.

DEXA instruments has a source that generates x-rays split into two energies which measures bone mineral mass and soft tissue from which fat and fat-free mass (or lean body mass) are estimated.
Percentage of Participants Who Achieved at Least a 10% BMI Reduction at Week 52 Baseline up to Week 52 Percent Change in Hemoglobin A1c (HbA1c) From Baseline up to Week 52 in Participants With Type 2 Diabetes Mellitus at Baseline Baseline up to Week 52 Percent change in HbA1c was analyzed for participants with Type 2 diabetes mellitus at baseline. Percent change from baseline was calculated as: \[post-baseline value minus the baseline value\]/baseline value)\*100.
Change in Fasting Insulin From Baseline up to Week 52 in Participants Without Type 2 Diabetes Mellitus at Baseline Baseline up to Week 52 Change in Total Body Fat Mass From Baseline up to Week 52 Using Dual-energy X-ray Absorptiometry (DEXA) Baseline up to Week 52 DEXA is used to assess changes in body composition, including total fat and lean body mass and appendicular skeletal fat and muscle mass. DEXA instruments has a source that generates x-rays split into two energies which measures bone mineral mass and soft tissue from which fat and fat-free mass (or lean body mass) are estimated.
Change in Fasting Plasma Glucose From Baseline up to Week 52 for Participants With Type 2 Diabetes Mellitus at Baseline Baseline up to Week 52 Change in fasting glucose was analyzed for participants with Type 2 diabetes mellitus at baseline. Change from baseline was calculated as the post-baseline value minus the baseline value.
Change in Blood Pressure (Systolic and Diastolic) From Baseline up to Week 52 Baseline up to Week 52 Systolic blood pressure is the maximum arterial pressure during contraction of the ventricles of the heart. Diastolic blood pressure is the minimum arterial pressure during relaxation and dilatation of the ventricles of the heart when the ventricles fill with blood.
Change in Heart Rate From Baseline up to Week 52 Baseline up to Week 52 Heart rate is the number of heart beats per unit of time, usually per minute.
Percentage of Participants by Study Drug Compliance Category During 52 Weeks of Treatment Up to Week 52 Treatment compliance is defined as: (Total number of tablets dispensed minus total number of tablets lost or returned)/total number of tablets participant should have taken during the actual treatment. Compliance to study drug was categorized as less than (\<) 80%, 80% to 100%, greater than (\>) 100% to less than equal to (\<=) 120%, and \>120%.
Percentage of Participants Who Achieved at Least a 5 Percent (%) BMI Reduction at Week 52 Baseline up to Week 52 Percent Change in BMI From Baseline up to Week 52 Baseline up to Week 52 Percentage of Participants With Dyslipidemia at Week 52 Week 52 Dyslipidemia is defined as abnormally high cholesterol.
Percentage of Participants Who Achieved at Least a 5% BMI Reduction at Week 12 Baseline up to Week 12 Change in Fasting Insulin From Baseline up to Week 52 for Participants With Type 2 Diabetes Mellitus at Baseline Baseline up to Week 52 Change in fasting insulin was analyzed for participants with Type 2 diabetes mellitus at baseline. Change from baseline was calculated as the post-baseline value minus the baseline value.
Change in Homeostatic Model Assessment-insulin Resistance (HOMA-IR) From Baseline up to Week 52 for Participants With Type 2 Diabetes Mellitus at Baseline Baseline up to Week 52 HOMA-IR measures insulin resistance based on fasting glucose and insulin measurements: HOMA IR=fasting plasma insulin (micro international units per milliliter \[µIU/mL\]\*fasting plasma glucose (mmol/L)/22.5. A higher number indicates a greater insulin resistance.
Change in Fasting Plasma Glucose From Baseline up to Week 52 in Participants Without Type 2 Diabetes Mellitus at Baseline Baseline up to Week 52 Change in HOMA-IR From Baseline up to Week 52 in Participants Without Type 2 Diabetes Mellitus at Baseline Baseline up to Week 52 HOMA-IR measures insulin resistance based on fasting glucose and insulin measurements: HOMA IR=fasting plasma insulin (µIU/mL\*fasting plasma glucose (mmol/L)/22.5. A higher number indicates a greater insulin resistance.
Change in Fasting Lipid Profile (Total Cholesterol, Low-density Lipoprotein [LDL] Cholesterol, High-density Lipoprotein [HDL] Cholesterol, Triglycerides) From Baseline up to Week 52 Baseline up to Week 52 Total Cholesterol is a measure of the total amount of cholesterol in blood. It includes both LDL cholesterol and HDL cholesterol. LDL cholesterol is often called the "bad" cholesterol because it collects in the walls of blood vessels, raising chances of health problems like a heart attack or stroke. HDL cholesterol is known as the "good" cholesterol because it helps remove other forms of cholesterol from bloodstream. Triglycerides are the most common type of fat in the body.
Percentage of Participants With Prehypertension or Primary Hypertension at Week 52 Week 52 Hypertension is defined as abnormally high blood pressure.
