Study to Assess the Pharmacokinetics of GSK1278863A Coadministered With a High Fat Meal or an Inhibitor of CYP2C8 (Gemfibrozil)

The purpose of this study is to assess the clinical drug-drug interaction potential of GSK1278863A with medications that are inhibitors of CYP2C8 enzyme in order to support co-administration of similar agents in later phase development. Specifically. this study will assess the pharmacokinetics of a single dose of GSK1278863A administered alone or co-administered with gemfibrozil, a potent inhibitor of CYP2C8, following steady-state oral administration of gemfibrozil. Finally, to support the co-administration of GSK1278863A with food, this study will assess the pharmacokinetics of a single oral dose of GSK1278863A under fasting conditions and following a standard high-calorie, high fat meal.
