Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • The safety and tolerability endpoints will be: adverse events, laboratory values, cardiovascular variables (blood pressure, heart rate, ECG), temperature, respiratory rate, assessment of mood and abnormal movements, and GSK618334 blood levels. [ Time Frame: First dose to follow-up ] [ Designated as safety issue: Yes ]
  • To assess blood concentrations of GSK618334 after repeated oral doses. [ Time Frame: First dose to 72 hours post last dose ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To assess the effect of food on GSK618334 blood concentrations after a single dose. [ Time Frame: First dose of the single dose session to 24 hours after dosing of the repeat dose session ] [ Designated as safety issue: No ]
  • The dopamine type 3 receptor binding in the brain (by PET scan) of GSK618334 following the repeat dose session. [ Time Frame: First dose to 24 hours after last dose ] [ Designated as safety issue: No ]

Detailed Description:
GSK618334 strongly binds to dopamine type 3 receptors in the human brain and is being developed as an innovative treatment for substance dependence. This study will evaluate the safety, tolerability, blood concentrations and effect following repeated oral doses of GSK618334 in healthy male and female volunteers. The effect of food on a single oral dose of GSK618334 will also be evaluated. Another portion of this study will investigate dopamine type 3 receptor binding in the human brain by PET scan before and after repeated doses of GSK618334.
