Arm Intervention/treatment
Experimental: Pazopanib receivers
During Days 1 and 2 subjects will be dosed with only probe drugs, and with no drugs on Days 3-5. During Days 6 to the end of the study, subjects will receive 800 mg daily pazopanib, and on Days 23-24 subjects will receive probe drugs in addition to pazopanib
Drug: GW786034 (pazopanib)
Pazopanib will be given as monohydrochloride, 100 and 500 mg tablets.
Drug: Probe drugs
probe drugs will be oral midazolam (3 mg), warfarin (10 mg), omeprazole (40 mg), caffeine (200 mg), and dextromethorphan (30 mg).

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

Secondary Outcome Measures :
  1. 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 ]
