Brief summary
GW679769 may affect liver enzymes that metabolize dexamethasone and ondansetron. This study is designed to test the safety and the extent of the GW679769 affect on dexamethasone and ondansetron levels in humans.
Interventions
Casopitant (GW679769) tablets will be available as white, film-coated tablets containing 50 mg of GW679769 as the mesylate salt for oral administration.
Dexamethasone will be available as 4 mg tablets for oral administration and injection for IV administration.
Ondansetron for oral use will be available as 8 mg tablets to be taken with 240 milliliters (mL) of water on an empty stomach. For IV use, ondansetron 32 mg will be infused intravenously over a period of 15 minutes.
