  • Masking: None (Open Label)

Arms and Interventions

Participant Group / 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
Pazopanib will be given as monohydrochloride, 100 and 500 mg tablets.
probe drugs will be oral midazolam (3 mg), warfarin (10 mg), omeprazole (40 mg), caffeine (200 mg), and dextromethorphan (30 mg).
