The DISCOVERY Study is a new, national effort to learn about the causes of type 2 diabetes in children. DISCOVERY is for children 9-14 years old who are at higher risk of developing type 2 diabetes. We want to figure out why some children get type 2 diabetes and others do not.

The purpose of this study is to evaluate how safe and effective the drug Qsymia (Phentermine/Topiramate of Ph/T) is for children, adolescents, and young adults with hypothalamic obesity. We will also evaluate if Ph/T helps with weight loss and changes in hunger in patients with hypothalamic obesity.

If you are determined to be eligible, then your participation will last for approximately 8 months. Participants will be asked to complete up to 5 in-person visits and 5 telephone safety check-ins. During the study you will be randomly assigned to study drug (phentermine/topiramate) or placebo for 28 weeks.

You will complete study procedures including blood tests, ECGs, mobile cardiac outpatient telemetry, body composition scan, and questionnaires. Compensation and reimbursement of limited travel expenses is available.
