Study to Evaluate the Efficacy, Safety and Pharmacokinetics of Three-times Weekly Dosing of GSK1278863 in Hemodialysis-dependent Subjects With Anemia Associated With Chronic Kidney Disease Who Are Switched From a Stable Dose of an Erythropoiesis-stimulating Agent

Study Overview
=================
Brief Summary
-----------------
GSK1278863 is an orally available, hypoxia-inducible factor - prolyl hydroxylase inhibitor, currently being investigated as a treatment for anemia associated with chronic kidney disease. GSK1278863 has been given as a once daily regimen in clinical studies to date. However, physicians in countries that use a three-times weekly hemodialysis schedule prefer to give the anemia medicine at the same time as the dialysis session. This study will test how well GSK1278863 can maintain hemoglobin levels when given three-times weekly, for 29 days. This study will describe the relationship between hemoglobin and GSK1278863 given three-times weekly. The data from this study will allow for conversion of once daily doses to three-times weekly doses.

Metabolite plasma concentrations were analyzed but PK parameters could not be calculated as the metabolites were partially eliminated through dialysis and the dialysis start and end times were not consistent on both PK days. Therefore, a representative metabolite PK profile could not be generated. The analysis was performed on PK Population, which comprised of all participants from whom a PK sample has been obtained and analyzed. Only those participants available at the specified time points were analyzed (represented by n=X in the category titles). | Pre-dose on Day 1; 6-10 hours, 7-11 hours, 8-12 hours, 9-13 hours post dose on Day 15; pre-dose and 1, 2, 3 hours post-dose on Day 29 |

The data from each PK sampling day was combined to generate a single profile, and normalized to a 24-hour period to create a Day 1 profile for NCA. Metabolite plasma concentrations were analyzed but PK parameters could not be calculated as the metabolites were partially eliminated through dialysis and the dialysis start and end times were not consistent on both PK days. Therefore, a representative metabolite PK profile could not be generated. | Pre-dose on Day 1; 6-10 hours, 7-11 hours, 8-12 hours, 9-13 hours post dose on Day 15; pre-dose and 1, 2, 3 hours post-dose on Day 29 |
