Study Endpoints

Primary Endpoints

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.
First dose to follow-up
To assess blood concentrations of GSK618334 after repeated oral doses.
First dose to 72 hours post last dose
Binding of PHNO, PET ligand, in each region of interest at each scan.

up to 48 hours
Time course of GSK618334 concentration in blood following a single oral dose.
up to 48 hours
Safety measures: ECG, Vital Signs, Adverse Events
for 48 hours after dosing.

Cohort 1EXPERIMENTALSubjects in Cohort 1 will be randomized to one of the following sequences: ABDFH, BADFH, BDAFH, BDFAH and BDFHA in a 1:1:1:1:1 ratio where A = Placebo, B= GSK618334 dose 1 (2.5 mg), D = GSK618334 dose 3, F = GSK618334 dose 5, H = GSK618334 dose 7. On day 1, subjects will be administered a starting dose of 2.5 milligrams (mg) GSK618334. The planned doses of GSK618334 to be administered in Cohort 1 are 2.5, 25, 100 and 400mg. In each dosing period 2 subjects will receive placebo and 8 subjects will receive GSK618334. Subjects within a cohort will have a washout period of at least two weeks from last dose before receiving another dose.
Cohort 2EXPERIMENTALSubjects in Cohort 2 will be randomized to one of the following sequences: ACEGI, CAEGI, CEAGI, CEGAI, CEGIA in a 1:1:1:1:1 ratio where A = Placebo, C= GSK618334 dose 2, E = GSK618334dose 4, G = GSK618334 dose 6, I= GSK618334 dose 8. In each dosing period 2 subjects will receive placebo and 8 subjects will receive GSK618334. Subjects within a cohort will have a washout period of at least two weeks from last dose before receiving another dose.
