Primary Outcome Measures:
  • To investigate the potential of GW786034 to inhibit or induce various CYP450 enzymes. [ Time Frame: throughout the study ]

Secondary Outcome Measures:
  • Safety of co-administration of 800 mg daily GW786034 and CYP450 probe drugs. To describe GW786034 steady-state pharmacokinetics on this once daily dosing regimen. [ Time Frame: throughout the study ]
