Summary

GSK1360707 is a potent re-uptake inhibitor of the neurotransmitters dopamine, norepinephrine and serotonin. This is a single dose PET study in healthy subjects.A final analyses of safety data following exposure to single oral doses, from the first time in human study, with GSK1360707 has demonstrated that the compound is well tolerated up to a dose of 150mg. This imaging study will be an open label, non-randomised PET occupancy study using healthy male volunteers. The degree and time course of DAT and SERT occupancy by GSK1360707 will be determined. The PK/PD relationship between plasma concentrations of GSK1360707 and DAT and SERT occupancy will be described.This protocol amendment includes the flexibility to split the total dose into two doses e.g. 120mg per day could be split into two doses of 60mg. Splitting the total dose is most likely required to maintain therapeutic occupancy on the transporters over the course of the day; in addition it is expected that splitting the dose may reduce effects on vital signs. Therefore collecting data following split dosing will enable best predictions of therapeutic doses to be progressed in subsequent clinical studies.

GSK1360707 is a potent re-uptake inhibitor of the neurotransmitters dopamine, norepinephrine and serotonin

This is an open label, adaptive design, daily dosing, non-randomized PET occupancy study in healthy adult males.A range of doses may be evaluated. The initial dose, given in the study as a single dose was 150mg GSK1360707. The remaining subjects will be dosed either as a single or split dose, as determined by the PET and tolerability data collected in the preceding subjects. The total dose will not exceed 150mg per day, the maximum total dose given in the FTIH study.If dosing is conducted as a single dose, the dose will be administered after the baseline scan, If a dosing is performed in a split dose manner, dosing will occur after the baseline scan, and up to 12 hours later. The time period between doses will be determined by emerging PET occupancy data. Subsequent doses, if any, will be chosen based on the observed scan results. No single dose, or total dose split over 2 dosing sessions, will exceed the maximum dose in the FTIH study.
