GlaxoSmithKline
  Purpose
Study to compare PK of a new 100mg capsule with four 25mg capsules. This is required because we plan to have only single capsules administered in the later phase clinical trials but we have not had a 100mg strength before. As this is a new previously untested strength we need to ensure that the PK is similar to that achieved using 4 x 25mg. The study will also assess the effect of high fat food on the PK of the 100mg capsule. The study is planned to consist of a single part , with three dosing periods, periods 1-3 consisting of 16 subjects. There will be a week wash out between each dose. In the three dosing periods subjects will either received 4x25 mg GSK598809 capsule in a fasted state, 100mg capsule in a fasted state or 100mg GSK598809 capsule in a fed state. Subjects will return to the centre for follow-up 7-14 days after the final dose. It is expected that the total duration of the study should be approximately eight weeks.

Official Title: An Open Label, Randomised, Single Dose, Three-way Crossover Study to Investigate the Relative Bioavailability of a 100mg Capsule Compared to Four 25mg GSK598809 Capsules and the Effect of Food on the Pharmacokinetics of the 100mg Capsule in Healthy Male and Female Volunteers.

Primary Outcome Measures:
  • Blood sampling over a period of 96hrs post GSK598809 dosing in the three dosing periods. [ Time Frame: Pre-dose, 0, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8. 10, 12, 16, 24, 48. 72 and 96 hours ]

Secondary Outcome Measures:
  • Safety and Tolerability: cardiovascular variables, vital signs, clinical labs, movement scales, prolactin, GH and TSH levels over 96 hours post dosing. Continuous adverse event monitoring from dosing until study conclusions. [ Time Frame: Up to 96 hours ]
