Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Daprodustat
Treatment: Drugs - rhEPO
Treatment: Drugs - Placebo
Treatment: Drugs - Iron therapy

Experimental: Daprodustat - Participants will receive oral daprodustat once daily.

Active comparator: rhEPO - Participants on peritoneal dialysis (PD) will be administered darbepoetin alfa subcutaneously (SC) and participants on hemodialysis (HD) will be administered epoetin alfa intravenously (IV).


Treatment: Drugs: Daprodustat
Daprodustat dose is based on prior ESA dose, the dose is adjusted thereafter in order to achieve the target range.

Treatment: Drugs: rhEPO
The initial ESA dose is based on converting the prior ESA dose to the nearest available study rhEPO dose and is administered IV. The dose is adjusted thereafter in order to achieve the target range.

Treatment: Drugs: Placebo
Oral placebo tablets will be taken from Week -4 up to randomization (Day 1).

Treatment: Drugs: Iron therapy
Participants will receive supplemental iron therapy if ferritin is \<=100 ng/mL or TSAT is \<=20%. The investigator will choose the route of administration and dose of iron.

* 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.
