Trial overview
Official title: A placebo-controlled, single blind, randomized two part study toinvestigate the tolerability, pharmacokinetics, and brainDopamine D3 receptor occupancy of increasing repeat doses ofGSK618334 for up to 21 days in healthy volunteers.
Trial description: The proposed study will evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics of repeated oral doses of GSK618334 in healthy male and female volunteers.
Primary purpose:
Other
Trial design:
Single Group Assignment
Masking:
Double (Participant, Investigator)
Allocation:
Randomized
Primary outcomes:
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.
Timeframe: First dose to follow-up
To assess blood concentrations of GSK618334 after repeated oral doses.
Timeframe: First dose to 72 hours post last dose
Secondary outcomes:
To assess the effect of food on GSK618334 blood concentrations after a single dose.
Timeframe: First dose of the single dose session to 24 hours after dosing of the repeat dose session
The dopamine type 3 receptor binding in the brain (by PET scan) of GSK618334 following the repeat dose session.
Timeframe: First dose to 24 hours after last dose
