|Condition or disease||Intervention/treatment||Phase|
|Weight Gain||Drug: metformin Drug: placebo||Phase 2|
This is a 24 week, placebo-controlled, random assignment pilot study in which participants will be randomized in a 1:1 ratio to receive either flexible-dose treatment with metformin for 6 months as well as a newly initiated second generation antipsychotic medication or to receive placebo and the newly initiated antipsychotic medication. All subjects will also be provided healthy lifestyle instruction. The study involves monthly visits for the duration of the study. Participants may be treated as inpatients or outpatients throughout the course of the study. Participants will receive a psychiatric evaluation, physical exam, lab work, ECG, medication treatment, and psychiatric care.
The goal is to evaluate the safety and efficacy of means to prevent and treat weight gain and the associated endocrine, metabolic, and inflammatory changes caused by antipsychotic medications. Behavioral treatments to reduce weight gain and metabolic problems after weight gain has occurred have had little impact. Such interventions must be intensive and sustained over months, if not years to be effective. Although basic lifestyle instruction (diet and physical activity) should be the standard of care for all children and adolescents at risk for becoming overweight, pharmacologic interventions may be the best option for substantially augmenting behavioral approaches to weight management.

- Change From Baseline to Week 24 in Body Mass Index (BMI) [ Time Frame: 0-24 weeks ]Change in BMI-Body Mass Index (BMI) is a measure of body fat based on height, weight,gender and chronological age. Change in BMI is calculated as 24 weeks BMI minus the baseline BMI.
- Change From Baseline to Week 24 in Weight [ Time Frame: 24 weeks ]Change in weight is calculated as 24 weeks weight minus the baseline weight.
- Change From Baseline to Week 24 in Fat Mass [ Time Frame: 24 weeks ]Fat mass is a measure of excess body fat. Change in Fat Mass is calculated as 24 weeks fat mass minus the baseline fat mass.
- Change From Baseline to Week 24 in Insulin Level [ Time Frame: 24 weeks ]Insulin is a peptide hormone and regulates carbohydrate and fat metabolism in the body.Change in Insulin level is calculated as the 24 weeks insulin level minus the baseline insulin level.
- Change From Baseline to Week 24 in Cholesterol Level [ Time Frame: 24 weeks ]According to the lipid hypothesis, abnormal cholesterol levels are strongly associated with cardiovascular disease because these promote atherosclerosis.Cholesterol levels are measured in milligrams (mg) of cholesterol per deciliter(dL) of blood.Change in cholesterol levels is measured at 24 weeks minus the levels at baseline.
- Change From Baseline to Week 24 in Triglycerides [ Time Frame: 24 weeks ]In the human body, high levels of triglyceride fats in the bloodstream have been linked to atherosclerosis and, by extension, the risk of heart disease and stroke. A change in triglycerides is calculated from 24 weeks minus baseline levels.
- Incidence of Metabolic Syndrome [ Time Frame: 24 weeks ]Metabolic syndrome is a combination of the medical disorders that, when co-occurring, increase the risk of developing cardiovascular disease and diabetes.
