Role of Pharmacotherapy in Counteracting Weight Regain in Adolescents with Severe Obesity


In this study we want to find out more about weight loss and how diet and medications can affect weight loss. This study will last for up to 58 weeks. There are two phases to the study: - A weight loss phase with prescribe meals that lasts 6 weeks. - A study medication/placebo phase that lasts up 52 weeks. You will not know if you are receiving the medication or the placebo.
