Who can join

Age: 18 and older, up to 99. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Age: 18 to 99 years of age (inclusive).
Erythropoietin-stimulating agents (ESAs): Use of any approved ESA for at least the 6 weeks prior to screening and between screening and randomization.
Hgb concentration: On Week -8: Hgb 8 to 12 grams per deciliter (g/dL). On randomization (Day 1): Hgb 8 to 11 g/dL and receiving at least the minimum ESA dose. Hgb >11 g/dL to 11.5 g/dL and receiving greater than the minimum ESA dose.
Dialysis: On dialysis >90 days prior to screening and continuing on the same mode of dialysis from screening (Week -8) through to randomization (Day 1).
Frequency of Dialysis: Hemodialysis (HD) >=2 times/week and peritoneal dialysis (PD) >=5 times/week. Home hemodialysis >=2 times/week.
Compliance with placebo [randomization (Day 1) only]: >=80% and <=120% compliance with placebo during run-in period.
Informed consent (screening only): capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the consent form and in this protocol.

You may not qualify if…

Kidney transplant: Planned living-related or living-unrelated kidney transplant within 52 weeks after study start (Day 1).
Ferritin: <=100 nanograms (ng)/milliliter (mL) (<=100 micrograms/liter [L]) at screening.
Transferrin saturation (TSAT) (screening only): <=20%.
Aplasias: History of bone marrow aplasia or pure red cell aplasia.
Other causes of anemia: Untreated Pernicious anemia, thalassemia major, sickle cell disease or myelodysplastic syndrome.
Gastrointestinal (GI) bleeding: Evidence of actively bleeding gastric, duodenal, or esophageal ulcer disease or clinically significant GI bleeding <=4 weeks prior to screening through to randomization (Day 1).
MI or acute coronary syndrome: <=4 weeks prior to screening through to randomization (Day 1).
Stroke or transient ischemic attack: <=4 weeks prior to screening through to randomization (Day 1).
Heart failure (HF): Chronic Class IV HF, as defined by the New York Heart Association (NYHA) functional classification system.
Current uncontrolled hypertension: Current uncontrolled hypertension as determined by the investigator that would contraindicate the use of recombinant human erythropoietin (rhEPO).
Bazett's corrected QT interval (QTcB) (Day 1): QTcB >500 millisecond (msec), or QTcB >530 msec in subjects with bundle branch block. There is no QT Interval Corrected for Heart Rate (QTc) exclusion for subjects with a predominantly ventricular paced rhythm.
Alanine transaminase (ALT): >2x upper limit of normal (ULN) at screening.
Bilirubin: >1.5xULN at screening.
Current unstable liver or biliary disease per investigator assessment, generally defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminaemia, esophageal or gastric varices, persistent jaundice, or cirrhosis.
Malignancy: History of malignancy within the 2 years prior to screening through to randomization (Day 1) or currently receiving treatment for cancer, or complex kidney cyst (example [e.g.] Bosniak Category II F, III or IV) > 3 centimeter (cm); with the exception of localized squamous cell or basal cell carcinoma of the skin that has been definitively treated >=4 weeks prior to screening.
Severe allergic reactions: History of severe allergic or anaphylactic reactions or hypersensitivity to excipients in the investigational product, or epoetin alfa or darbepoetin alfa.
Drugs and supplements: Use of strong inhibitors of Cytochrome P4502C8 (CYP2C8) (e.g., gemfibrozil) or strong inducers of CYP2C8 (e.g., rifampin/rifampicin).
Other study participation: Use of other investigational agent or device prior to screening through to randomization (Day 1).
Prior treatment with daprodustat: Any prior treatment with daprodustat for treatment duration of >30 days.
Females only: Subject is pregnant [as confirmed by a positive serum human chorionic gonadotrophin (hCG) test for females of reproductive potential (FRP) only], subject is breastfeeding, or subject is of reproductive potential and does not agree to follow one of the contraceptive options listed in the List of Highly Effective Methods for Avoiding Pregnancy.
Other Conditions: Any other condition, clinical or laboratory abnormality, or examination finding that the investigator considers would put the subject at unacceptable risk, which may affect study compliance (e.g., intolerance to rhEPO) or prevent understanding of the aims or investigational procedures or possible consequences of the study.
