Brief summary:
This study is intended to evaluate the dose-response relationship of GSK1278863 over the first 4 weeks of treatment and evaluate the safety and efficacy of GSK1278863 over 24 weeks to maintain hemoglobin (Hgb) level in hemodialysis-dependent (HDD) subjects with anemia associated with chronic kidney disease (CKD) who are switched from a stable dose of recombinant human erythropoietin (rhEPO). The data generated will enable selection of the starting dose(s) and optimize dose adjustment regimen(s) for Phase 3 clinical trials.

Detailed description:

Arms:
arm 1: Subjects will take GSK1278863 4 mg blinded once daily (OD) orally for 4 weeks with a glass of water. From Week 4, study medication will continue to be administered OD and the dose will be adjusted based on Hgb levels dose every 4 weeks till Week 24. arm 2: Subjects will take GSK1278863 6 mg blinded OD orally for 4 weeks with a glass of water. From Week 4, study medication will continue to be administered OD and the dose will be adjusted based on Hgb levels dose every 4 weeks till Week 24. arm 3: Subjects will take GSK1278863 8 mg blinded OD orally for 4 weeks with a glass of water. From Week 4, study medication will continue to be administered OD and the dose will be adjusted based on Hgb levels dose every 4 weeks till Week 24. arm 4: Subjects will take GSK1278863 10 mg blinded OD orally for 4 weeks with a glass of water. From Week 4, study medication will continue to be administered OD and the dose will be adjusted based on Hgb levels dose every 4 weeks till Week 24. arm 5: Subjects will take GSK1278863 12 mg blinded OD orally for 4 weeks with a glass of water. From Week 4, study medication will continue to be administered OD and the dose will be adjusted based on Hgb levels dose every 4 weeks till Week 24. arm 6: Subjects will take GSK1278863 matching placebo blinded OD orally for 4 weeks with a glass of water. From Week 4, rhEPO will be administered and the dose will be adjusted based on Hgb levels dose every 4 weeks till Week 24.
