NCT03029247

Brief Summary

This will be an open-label, randomized, parallel-group study in hemodialysis-dependent (HD) participants with anemia associated with chronic kidney disease (CKD), designed to compare the effects of daprodustat to epoetin alfa on blood pressure (BP). Participants will be screened for eligibility within 7 and 30 days prior to erythropoesis-stimulating agent (ESA) washout. Following a 2-week ESA washout period, on Day 1 participants will be randomized 1:1 and stratified by prior ESA dose before they undergo Acute Challenge 1, a single dose challenge to compare the acute effects on BP of the highest planned once-daily maintenance dose of daprodustat (24 milligrams \[mg\]) to the highest starting dose of epoetin alfa (100 units/kilogram \[U/kg\]). This will be followed by an 8-week hemoglobin (Hgb)-maintenance period, where doses of either daprodustat or epoetin alfa will be administered and adjusted. At the end of Hgb maintenance period, on Day 57 an Acute Challenge 2 will be repeated utilizing the same treatment dose administered in Acute Challenge 1; there will be a follow-up visit within 14+/-3 days after completing treatment.

Outcome Measures

Primary Outcomes (1)

  • Average of Systolic Blood Pressure (SBP) Measured by Ambulatory Blood Pressure Monitoring (ABPM) Over 6-hour Post Dosing on Day 57

    The effect of daprodustat and epoetin alfa on blood pressure was compared using ABPM after 8 weeks of Hgb maintenace therapy on Day 57. Analysis was based on "analysis of covariance (ANCOVA) with terms for treatment, prior erythropoiesis-stimulating agent (ESA) dose (low/high), post-Hemodialysis dependent (HD)/pre-AC 1 SBP, difference between post-HD/pre-AC 2 SBP and post-HD/pre-AC 1 SBP and treatment by difference in post-HD SBP between AC 1 and 2 interaction." Least square (LS) mean of 6 hour average SBP post AC2 on Day 57 and its corresponding standard error has been presented.

    Up to 6 hours post dose on Day 57

Secondary Outcomes (21)

  • Average of SBP, Diastolic Blood Pressure (DBP) and Mean Arterial Blood Pressure (MAP) Measured by ABPM Over 6-hour Post Dosing on Day 1

    Up to 6 hours post dose on Day 1

  • Average of Heart Rate (HR) Measured by ABPM Over 6 Hour Post Dosing on Day 1

    Up to 6 hours post dose on Day 1

  • Area Under the Effect Curve (AUEC) of SBP, DBP and MAP Measured by ABPM Over 24-hour Post Dosing on Day 1

    Up to 24 hours post dose on Day 1

  • AUEC of HR Measured by ABPM Over 24-hour Post Dosing on Day 1

    Up to 24 hours post dose on Day 1

  • Average of DBP and MAP Measured by ABPM Over 6-hour Post Dosing on Day 57

    Up to 6 hours post dose on Day 57

  • +16 more secondary outcomes

Other Outcomes (35)

  • Number of Participants With Any Serious Adverse Events (SAEs)

    Up to Week 10

  • Number of Participants With Treatment Emergent Common (>=2%) Non-serious Adverse Events (Non-SAEs)

    Up to Week 8

  • Number of Participants Who Discontinued the Study Treatment

    Up to Week 10

  • +32 more other outcomes

Study Arms (2)

Participants receiving Epoetin alfa

ACTIVE COMPARATOR

On Day 1, participants will undergo 24-hour Acute Challenge 1, in which participants will receive a single dose of 100 U/kg epoetin alfa IV. After completing Acute Challenge 1, participants will enter in an 8-week Hgb maintenance period. At the end of Hgb maintenance period, on Day 57, Acute Challenge 2 will be performed utilizing the same treatment dose administered in Acute Challenge 1.

Drug: Epoetin alfa

Participants receiving Daprodustat

EXPERIMENTAL

On Day 1, participants will undergo 24-hour Acute Challenge 1, in which participants will receive 24 mg daprodustat. After completing Acute Challenge 1, participants will enter an 8-week Hgb maintenance period. At the end of Hgb maintenance period, on Day 57, Acute Challenge 2 will be performed utilizing the same treatment dose administered in Acute Challenge 1.

Drug: Daprodustat

Interventions

Daprodustat will be available as oral tablets at unit dose strength of 1, 2, 4, 6, 8 and 10 mg.

Participants receiving Daprodustat

Epoetin alfa will be administered according to local labelling and clinical practice guidelines to keep Hgb in the target range (10.0-11.0 g/dL)
