Purpose:

The purpose of this study is to evaluate the effect of rimonabant, a cannabinoid receptor-1 blocking drug, on the appetite, body weight, body fat and growth hormone level of subjects with Prader-Willi Syndrome (PWS). This will be a double blind placebo controlled clinical trial involving a total of 18 young adults aged 18 to 35 years with PWS. Patients will be divided in to the two groups of control and intervention, and treated with either placebo (inactive drug), or rimonabant 20 mg once a day for a total duration of 6 months. Body weight, fat distribution, objective and subjective assessment of the hunger, fasting blood sample for measurement of ghrelin and leptin (two hormones regulating appetite), serum lipids , IGF-1(growth hormone related protein), insulin and glucose concentrations will be measured upon enrollment, at 3 months, and at the end of the study. The proportion of body fat to muscle will be determined using a radiological technique, whole body dual-energy x-ray absorptiometry (DEXA) scan, and also by measurement of skin fold thickness, waist and hip circumference at the enrollment prior to the intervention, and at the end of the study.

Inclusion Criteria: 1. Subjects will be selected if they have Prader Willi Syndrome previously confirmed by standard genetic testing (the DNA methylation test) or meet the clinical diagnostic criteria as follows :the presence of at least four of the six principal characteristics of PWS syndrome including 1) infantile hypotonia, 2) abnormal pubertal development, 3) obesity after early infancy, 4) dysfunctional central nervous system performance, 5) dysmorphic facial features, and 6) short stature.

Presence of any other abnormal endocrine findings, including abnormal thyroid function. 3. Presence of significant behavioral problems or psychiatric illness including anxiety disorder and depression, interfering with the follow up of protocol. Any degree of depression and moderate to severe anxiety will be exclusion criteria for this study. 4. Subjects with Prader Willi Syndrome who are on other medications including growth hormone therapy, anti epileptic medications, or antipsychotic medications. 5. The presence of moderate to severe renal or liver disease. Mild elevations of liver enzymes are not exclusive. 6. Subjects who are on any other research or weight loss medication
