The purpose of this study is to investigate over a 6 month period the effect of octreotide therapy on food intake, sense of hunger, body weight, body composition, efficiency of burning calories, biomarkers of weight regulation and growth hormone markers in children and young Adults with Prader-Willi Syndrome(PWS).

Further study details as provided by Duke University:

Primary Outcome Measures:
  • Fasting total ghrelin, hunger and food intake as measured by hunger and hyperphagia by questionnaires, parent-reported 72-hour food recall, weight, height, BMI, skin-fold measurements. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Body-composition as measured by DEXA scan, the BOD POD body composition tracking system and bioelectrical impedance analysis (BIA). We will also measure resting metabolic rate, and hormone levels related to weight management. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Estimated Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Octreotide
    Octreotide or placebo to be administered by subcutaneous injection three times daily
    Other Name: Sandostatin
Detailed Description:

Obesity continues to be a prevalent health concern affecting every race of the American population. According to data from the World Health Organization, 54% of U.S. adults are overweight (body mass index (BMI) >25 kg/m2 ) and 22% are obese (BMI >30 kg/m2) (1). In addition, 25% of U.S. children are overweight or obese (1). Studies show that obese children are likely to become obese adults (2-5). Also, recent studies report significant years of life lost due to the impact of being an obese adult (6, 7). Thus, insights into the pathogenesis of childhood obesity and preventative measures are needed to combat the inevitable increase in worldwide incidence of obesity and its associated co-morbidities. Recent studies have identified a new gastroenteric hormone, ghrelin, as a long-term regulator of energy balance in humans (12). Ghrelin is a 28 amino acid acylated peptide which is an endogenous ligand of the growth hormone secretagogue receptor (GHS-R), a hypothalamic G-protein-coupled receptor (13). Enteroendocrine cells (X/A-like cells) of the stomach are the major site of ghrelin synthesis, although a minor proportion of ghrelin synthesis occurs in other sites such as the hypothalamus, pituitary, duodenum, jejunum and lung (14) (15, 16).

The hypothesis that hyperghrelinemia causes some of the features of PWS predicts that this disorder will be ameliorated (partially or completely) by lowering ghrelin levels. We have recently shown that the somatostatin agonist, octreotide, suppresses ghrelin levels in humans. If octreotide remains effective in longer term studies, the drug may become an adjuvant therapy, in addition to growth hormone, to control the insatiable appetite and morbid obesity seen in this condition.
