Summary

Prader-Willi Syndrome (PWS) is one of the most common genetic causes of obesity. Obesity is a major source of morbidity and mortality in this population. It can lead to sleep apnea, cor pulmonale, diabetes mellitus, and atherosclerosis. PWS has distinct characteristics that set it apart from other forms of obesity including insatiable appetite and food-seeking behavior which can be disruptive to home and school activities, and can cause severe social and psychological turmoil within families. PWS is also associated with unique hormonal abnormalities, most notably hyperghrelinemia. Ghrelin is a gut hormone produced in the stomach that stimulates food intake during a fast. It is hypothesized that the extremely high ghrelin levels in patients with PWS may cause or contribute to their insatiable appetite. Exenatide, a medication used in the treatment of type 2 diabetes mellitus in adults, appears to suppress ghrelin levels and cause weight loss. It was designed to mimic glucagon-like peptide 1 (GLP-1), an incretin hormone that stimulates insulin secretion and delays gastric emptying, among other effects. In the present study, the investigators will investigate the effects of a 6 month trial of exenatide in overweight adolescents with PWS. The investigators will quantify the changes in weight and body composition, as well as subjective measures of appetite, and concentrations of appetite-associated hormones. The investigators hypothesize that exenatide will improve weight, body composition, appetite, and plasma ghrelin levels during the treatment period.

Conditions

Interventions

DRUG

Exenatide

The investigators will give patients naive to GLP-1 agonists exenatide per manufacturer dosing recommendations for 6 months. The investigators will begin by giving 5 mcg subcutaneously twice a day for 1 month and then increase the dose to 10 mcg subcutaneously twice a day for the remainder of the study (5 months).
