Trial overview
Official title: A Phase 3 randomized, double-blind, active-controlled, parallel-group, multi-center study in hemodialysis participants with anemia of chronic kidney disease to evaluate the efficacy, safety and pharmacokinetics of three-times weekly dosing of daprodustat compared to recombinant human erythropoietin, following a switch from recombinant human erythropoietin or its analogs
Trial description: This Phase 3 study in hemodialysis-dependent subjects with anemia will evaluate the efficacy and safety of daprodustat administered three-times weekly compared to epoetin alfa, the current standard of care. This study includes a 4 week Screening Period, a 52 week Treatment Period and a 4 to 6 week follow-up period. Each subject will remain in the study for up to 62 weeks. Approximately 402 subjects will be randomized to receive either daprodustat three times weekly or epoetin alfa three-times weekly or once weekly, depending on dose level.

No
- Subject must be 18 to 99 years of age inclusive, at the time of signing the informed consent.
- Use of any approved rhEPO or analog for at least 8 weeks prior to the screening visit and continuing during the screening period until randomization (Day 1).

If Hgb is 11.6 to 11.9 grams/deciliter (7.2 to 7.4 millimoles/liter), up to two retests are allowed; the retest value must be between 8 to 11.5 grams/deciliter (5 to 7.1 millimoles/liter). Day 1: Hgb 8 to 11 grams/deciliter (5 to 6.8 millimoles/liter) and receiving at least the minimum rhEPO or analog dose 3.

- On hemodialysis (in-center) >=3 times per week.
- Male and female subjects are eligible. A female subject is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies: Not a woman of childbearing potential (WOCBP), or A WOCBP who agrees to follow the contraceptive guidance from at least 28 days prior to first dose of study treatment and for at least 28 days after the last dose of study treatment.

- History of severe allergic or anaphylactic reactions or hypersensitivity to excipients in the investigational product (daprodustat) or epoetin alfa.
