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

Inclusion Criteria

• More than or equal to 18 years of age, at the time of signing the informed consent.
• Hemoglobin: Stable Hemoglobin 9.0 - 11.5 gram per deciliter (g/dL).
• Dialysis frequency: On hemodialysis (HD, hemofiltration or hemodiafiltration) three to five times weekly for at least 4 weeks prior to Day -28 Screening through Day 29.
• Dialysis adequacy: A single pool Kt/Vurea of >=1.2 based on a historical value obtained within the prior three months in order to ensure the adequacy of dialysis. If Kt/Vurea is not available, then an average of the last 2 values of urea reduction ratio (URR) of at least 65 percent. NOTE: Only needs confirming at Day -28.
• Erythropoiesis-stimulating agent (ESA)dose: Treated with the same ESA (epoetins or their biosimilars, or darbepoetin or methoxy polyethylene glycol [PEG]-epoetin beta) with total weekly dose varying by no more than 50 percent during the 4 weeks prior to Day -28.
• Iron replacement therapy: Subjects may be on stable maintenance oral or intravenous (IV) ( =360 international unit (IU)/kilogram (kg)/week IV or >=250 IU/kg/week subcutaneous (SC) or darbepoetin dose of >=1.8 microgram (mcg)/kg/week IV or SC or methoxy PEG-epoetin beta dose of >= 2.2 mcg/kg/week within the prior 8 weeks through Day 1 (randomization).
• Administration of methoxy PEG-epoetin beta within the prior 4 weeks through Day 1 (randomization).
• Myocardial infarction or acute coronary syndrome: Within the 8 weeks prior to Screening through Day 1 (randomization).
• Stroke or transient ischemic attack: Within 8 weeks prior to Screening though Day 1 (randomization).
• Heart failure: Class IV heart failure, as defined by the New York Heart Association (NYHA) functional classification system diagnosed prior to Screening through Day 1 (randomization).
• Correction of Q-T Interval using Bazett's formula (QTcB): QTcB >500 millisecond (msec) or QTcB >530 msec in subjects with Bundle Branch Block. There is no correction of Q-T Interval (QTc) exclusion for subjects with a predominantly paced rhythm.
• Inflammatory disease: Active chronic inflammatory disease that could impact erythropoiesis (e.g., scleroderma, systemic lupus erythematosis, rheumatoid arthritis, celiac disease) diagnosed prior to Screening through Day 1 (randomization).
• Hematological disease: Any hematological disease including those affecting platelets, white or red blood cells (e.g., sickle cell anemia, myelodysplastic syndromes, hematological malignancy, myeloma, hemolytic anemia and thalassemia), coagulation disorders (e.g., antiphospholipid syndrome, Protein C or S deficiency), or any other cause of anemia of chronic disease other than renal disease diagnosed prior to Screening though Day 1 (randomization).
• Liver disease: Current liver disease, known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones) or evidence at Screening of abnormal liver function tests [alanine transaminase (ALT) or aspartate transaminase (AST) >2x upper limit of normal (ULN) or total bilirubin >1.5xULN]; or other hepatic abnormalities that in the opinion of the investigator would preclude the subject from participating in the study.

NOTE: Those with Hepatitis B or Hepatitis C are eligible provided these exclusions are not met.

• Major surgery: Major surgery (excluding vascular access surgery) within the 8 weeks prior to Screening, during the Screening phase, or planned during the study.
• Transfusion: Blood transfusion within the 8 weeks prior to Screening, during the Screening phase or an anticipated need for blood transfusion during the study.
• Gastrointestinal (GI) Bleeding: Evidence of actively bleeding peptic, duodenal, or esophageal ulcer disease OR clinically significant GI bleeding within the 8 weeks prior to Screening through Day 1 (randomization).
• Acute Infection: Clinical evidence of acute infection or history of infection requiring IV antibiotic therapy within the 4 weeks prior to Screening thr
