Key inclusion & exclusion criteria
|
Inclusion criteria: Patients with Prader-Willi Syndrome with inadequately controlled body weight (BMI > 25 kg/m2), and healthy volunteers (without diabetes), matched for age and adiposity. Are the trial subjects under 18? no Number of subjects for this age range: 0 F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 0 F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range 0
Exclusion criteria: For the Prader Willi Syndrome group: patients with Prader Willi Syndrome with adequately controlled body weight (BMI < 25 kg/m2) will be excluded for safety reasons (see above). Also patients with type 1 or 2 diabetes mellitus will be excluded. Exclusion criteria for control participants have been chosen because they will have a direct influence on eating behaviour and patterns. Participants with the following will be excluded: a history of eating disorder such as bulimia nervosa, anorexia nervosa or binge-eating disorder (according to DSM IV criteria), history of psychiatric disorder (schizophrenia, major depression, bipolar affective disorder), diabetes mellitus (type 1 or 2), current history of excess alcohol consumption or substance abuse or addiction, current (or within last 3 months) use of certain centrally acting medication (certain psychotropic or antidepressant medications) that are known to influence feeding behaviour, a history of traumatic brain injury, genetic forms of hypothalamic obesity (such as Prader-Willi syndrome, Biedl-Bardet syndrome). For all participants: the presence of metal implants or metal objects on the body which cannot be removed (those fitted with a heart pacemaker, mini-defibrillator or neurostimulator or have an artificial heart valve; surgical clips in the head; history of injury which may have left metal particles in the eye, head, or elsewhere in the body) will be excluded from the abdominal MRI aspect of the study, as these factors would pose a safety risk to the participant.

Health Condition(s) or Problem(s) studied
|
Ghrelin levels in patients with Prader Willi Syndrome and healthy controls and response of ghrelin levels to a single exenatide injection compared with placebo (0.9% sodium chloride) injection. MedDRA version: 14.0
Level: PT
Classification code 10036476
Term: Prader-Willi syndrome
System Organ Class: 10010331 - Congenital, familial and genetic disorders
|
Intervention(s)
|
Trade Name: Byetta Product Name: Byetta Product Code: EU/1/06/362/003: 5µg (1 pen) Pharmaceutical Form: Injection INN or Proposed INN: exenatide Concentration unit: µg microgram(s) Concentration type: equal Concentration number: 5- Pharmaceutical form of the placebo: Injection Route of administration of the placebo: Subcutaneous use
|
Primary Outcome(s)
|
Main Objective: To investigate the effects of exenatide (a synthetic compound which is currently licensed and used as a treatment option in type 2 diabetes that has well described appetite supressing and weight-losing properties) on circulating ghrelin levels (a hormone produced by the stomach), appetite and food intake in subjects with PWS.
|
Primary end point(s): The primary outcome measure of our proposed study will be the effects of exenatide on circulating ghrelin levels, ghrelin isoforms, appetite rating and food intake in subjects with PWS.
|
Secondary Objective: We will also analyse the expression of adipokines (fat hormones) in subcutaneous adipose (fat) tissue, obtained by needle biopsy, in subjects with Prader Willi Syndrome compared to weight and adiposity-matched controls. This will allow us to explore possible links with the abnormal body composition and fat distribution observed in Prader Willi Syndrome subjects.
