Brief Summary

This will be an open-label, parallel-group study to evaluate the pharmacokinetics of GSK1278863 and metabolites in normal subjects and subjects with impaired renal function, including those who are hemodialysis dependent. GSK1278863 will be administered once daily for 14 days to normal subjects and subjects with Stage 3 and Stage 4 renal function, and 15 days to subjects with Stage 5 renal function. Pharmacokinetic assessments will be made on Days 1 and 14 (normal subjects, subjects with Stage 3 and Stage 4 renal function) or Days 14 and 15 (dialysis and non-dialysis days; Stage 5).

• Is otherwise considered clinically stable with respect to underlying renal impairment as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and ECG.
• has clinical laboratory test results that are considered clinically stable in the opinion of the Investigator, especially if the clinical abnormality or laboratory parameter is deemed associated with the subject's underlying renal impairment.
• has AST, ALT, alkaline phosphatase and bilirubin < or = 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
