• •IV iron therapy: Use of IV iron for 4 weeks prior to Screening Week -4, during the screening phase, and through the first 4 weeks after Randomization
• •Vitamin B12: Below the lower limit of the reference range (may rescreen in a minimum of 8 weeks).
• •Folate: \<2.0 nanogram per millilitre (ng/mL) (\<4.5 nanomoles per liter \[nmol/L\]) (may rescreen in a minimum of 4 weeks).
• •Ferritin: \<40 ng/mL (\<40 mcg/L).
• •Transferrin saturation (TSAT): Below the lower limit of the reference range
• •Myocardial infarction or acute coronary syndrome: Within the 8 weeks prior to Screening through Day 1 (randomization).
• •Stroke or transient ischemic attack: Within the 8 weeks prior to Week -4 Screening through Day 1 (randomization).
• •Heart failure: Class III/IV heart failure as defined by the New York Heart Association (NYHA) functional classification system diagnosed prior to Week -4 Screening through Day 1 (randomization), symptomatic right heart failure diagnosed prior to Week -4 Screening through Day 1 (randomization).
• •Uncontrolled hypertension: Defined as diastolic blood pressure (DBP) \>100 mmHg or systolic blood pressure (SBP) \>170 mmHg at Week -4 and reconfirmed at Day 1.
• •Thrombotic Disease: History of thrombotic disease (e.g., venous thrombosis such as deep vein thrombosis or pulmonary embolism, or arterial thrombosis such as new onset or worsening limb ischemia requiring intervention), except vascular access thrombosis within the 8 weeks prior to Week -4 Screening through Day 1 (randomization).
• •Inflammatory disease: Active chronic inflammatory disease that could impact erythropoiesis (e.g., scleroderma, systemic lupus erythematosis, rheumatoid arthritis, celiac disease) diagnosed prior to Week -4 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 other than renal disease diagnosed prior to Week -4 Screening through 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 \[alanine transaminase (ALT) or aspartate transaminase (AST) \>2.0 x upper limit of normal (ULN) or total bilirubin \>1.5 x ULN\]; or other hepatic abnormalities that in the opinion of the investigator would preclude the subject from participation in the study.
• •Major surgery: Major surgery (excluding vascular access surgery) within the prior 8 weeks, during the Week -4 Screening phase or planned during the study.
• •Transfusion: Blood transfusion within the prior 8 weeks, during the Week -4 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 Week -4 Screening through Day 1 (randomization).
• •Acute infection: Clinical evidence of acute infection or history of infection requiring IV antibiotic therapy within the 8 weeks prior to Week -4 Screening through Day 1 (randomization).
• •Malignancy: Subjects with a history of malignancy within the prior 5 years, who receiving treatment for cancer, or who have a strong family history of cancer (e.g., familial cancer disorders); with the exception of squamous cell or basal cell carcinoma of the skin that has been definitively treated prior to Week -4 Screening through Day 1 (randomization).
• •Severe allergic reactions: History of severe allergic or anaphylactic reactions or hypersensitivity to excipients in the investigational product (see GSK1278863 IB for list of excipients and rhEPO (refer to local product labelling for details).
• •Drugs and supplements: Use of any prescription or non-prescription drugs or dietary supplements that are prohibited from Week -4 Screening until the Follow-up Visit.
• •Prior investigational product exposure: The Subject has participated in a clinical trial and has received an experimental investigational product within the prior 30 days from Week -4 Screening through Day 1 (randomization).
• •Other Conditions: Any other condition, clinical or laboratory abnormality, or examination finding that the Investigator considers would put the subject at unacceptable risk.
• •Patient participation: Unwillingness or inability of the subject to follow the procedures or lifestyle or dietary restrictions outlined in the protocol.
• •Pregnancy or Lactation: Pregnant females as determined by positive urine human chorionic gonadotropin (hCG) test OR women who are lactating at Week -4 Screening or during the trial.
