Anemia Studies in Chronic Kidney Disease: Erythropoiesis Via a Novel Prolyl Hydroxylase Inhibitor Daprodustat-Dialysis (ASCEND-D)

Inclusion Criteria

• 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 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.
