Effects of the D3 Antagonist GSK598809 on Food Reward and Reinforcement

2014-08-27 03:17:00 | BioPortfolio

Summary

This novel compound is a new experimental treatment that may help people to stop compulsive overeating. Compulsive overeating or binge eating is one of the main reasons why people are overweight or obese. Recent research has shown that some kinds of overeating may be linked to a brain chemical called dopamine. There is some evidence that blocking the action of this chemical in animals can reduce food intake, particularly of foods that are high in fat and sugar. The purpose of this study is to find out if this compound (which blocks the effects of dopamine) has the same effect in overweight or obese people, as it does in animals.

Description

This novel compound is being developed for the treatment of substance dependence and potentially other impulse control disorders.

This is an fMRI study designed to examine the behavioural and physiological effects of a single dose of novel compound on food reward and reinforcement in relation to food seeking behaviour under conditions of fasting, using fMRI, neurocognitive and metabolic endpoints in overweight and obese subjects. These main objectives will be evaluated in the principal part of the study, Part A. The study will also consist of a follow up period of weight management with a dietician where exploratory objectives are considered, Part B.

Part A, will be a single-blind, randomised, placebo controlled, multi-centre, two-period cross-over study. Approximately 24 subjects will be enrolled such that a minimum of 20 subjects complete dosing and critical assessments. All subjects will be required to complete questionnaires, perform a series of behavioural tasks and scanning procedures. Safety and tolerability will be assessed by monitoring subjects for adverse events, vital signs, ECGs, movement disorders (EPS, Akathisia) and laboratory parameters. The pharmacokinetic profile of the compound in this subject population will be determined by blood sampling over a 72 hour period post dosing, in both sessions. Part B will consist of 12 weeks weight management directed by a dietician on an outpatient basis. Subjects will have fortnightly visits with a dietician and at the end of the 12 weeks complete three questionnaires (TFEQ-18R, DBEQ and YBOCS-BE) and have their weight measured to assess weight loss.

Medical and Biotech [MESH] Definitions

An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. Most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides.

A product formed from skin, white connective tissue, or bone COLLAGEN. It is used as a protein food adjuvant, plasma substitute, hemostatic, suspending agent in pharmaceutical preparations, and in the manufacturing of capsules and suppositories.

A subclass of cartilaginous fish comprising the SHARKS; rays; skates (SKATES (FISH);), and sawfish. Elasmobranchs are typically predaceous, relying more on smell (the olfactory capsules are relatively large) than sight (the eyes are relatively small) for obtaining their food.

Hard or soft soluble containers used for the oral administration of medicine.

A disorder occurring at the site of insertion of TENDONS or LIGAMENTS into bones or JOINT CAPSULES.
