Summary
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.
Eligibility Criteria
Inclusion Criteria
- 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).
- Hgb concentration (measured by HemoCue) within the following range: Week -4: Hgb 8 to 11.5 grams/deciliter (5 to 7.1 millimoles/liter). 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. Hgb>11 to 11.5 grams/deciliter (6.8 to 7.1 millimoles/liter) and receiving greater than the minimum rhEPO or analog dose 3.
- On hemodialysis (including hemofiltration or hemodiafiltration) >90 days prior to screening and continuing during the screening period.
- 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.
- Capable of giving signed informed consent.
- In France, a subject will be eligible for inclusion in this study if he or she is either affiliated to or beneficiary of a social security category.
Exclusion Criteria
- Planned living-related or living-unrelated kidney transplant within 52 weeks after randomization (Day 1).
- Ferritin: 20 percent to confirm eligibility.
- Aplasias: History of bone marrow aplasia or pure red cell aplasia.
- Conditions, other than anemia of CKD, which can affect erythropoiesis.
- Myocardial infarction (MI) or acute coronary syndrome within 8 weeks prior to screening through to randomization (Day 1).
- Stroke or transient ischemic attack within 8 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 as determined by the investigator that would contraindicate the use of rhEPO.
- Bazett's correction of QTc interval (QTcB): at Day 1: QTcB >500 milliseconds, or QTcB >530 milliseconds in subjects with bundle branch block. There is no QTc (corrected QT) exclusion for subjects with a predominantly ventricular paced rhythm.
- Liver Disease: presence of any one of the following liver-related laboratory values or conditions, at screening, is exclusionary: ALT >2x upper limit of normal (ULN); Bilirubin >1.5x ULN; or Current unstable liver or biliary disease per investigator assessment, generally defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, persistent jaundice, or cirrhosis.
- Evidence of actively bleeding gastric, duodenal or esophageal ulcer disease OR clinically significant gastro intestinal bleeding 3 centimeters.
- Use of a strong inhibitor of Cytochrome P4502C8 [CYP2C8] (e.g. gemfibrozil) or a strong inducer of CYP2C8 (e.g. rifampin/rifampicin).
- History of severe allergic or anaphylactic reactions or hypersensitivity to excipients in the investigational product (daprodustat) or epoetin alfa.
- Use of another investigational agent within 30 days or within five half-lives of the investigational agent (whichever is longer) or currently participating in a study of an investigational device prior to screening through to randomization (Day 1).
- Any prior treatment with daprodustat for treatment duration of >30 days.
- Any other condition, clinical or laboratory abnormality, or examination finding that the investigator considers would put the subje
