Summary

This trial tests daprodustat, a drug that helps the body absorb more iron and make red blood cells, in adults with chronic kidney disease-related anemia who are not on dialysis. The study compares daprodustat to another treatment to see which is better at improving iron absorption. Daprodustat is a promising alternative for the treatment of anemia in patients with chronic kidney disease (CKD).

Trial Design

4Treatment groups

Experimental Treatment

Group I: rhEPO+58Fe followed by Daprodustat+57FeExperimental Treatment4 Interventions

Participants will be randomly assigned to remain on their current therapy (either epoetin alfa or darbepoetin alfa) in Treatment Period 1. For assessment of incorporation of iron into erythrocytes, participants will be administered ferrous sulfate containing a stable isotope of iron (58Fe) orally in a randomized fashion following 2 weeks of administration of randomized study treatment. At Day 29 participants will be crossed over to receive Daprodustat in Treatment Period 2. At 2 weeks following initiation of dosing in Treatment Period 2, participants will again be administered ferrous sulfate containing the stable iron isotope (57Fe) orally. Participants will be advised to maintain use of oral iron supplementation (except ferric citrate) and acid-reducing agents (example: H2 receptor antagonists, proton pump inhibitors, antacids) at a consistent dosage and frequency.

Group II: rhEPO+57Fe followed by Daprodustat+58FeExperimental Treatment4 Interventions

Participants will be randomly assigned to remain on their current therapy (either epoetin alfa or darbepoetin alfa) in Treatment Period 1. For assessment of incorporation of iron into erythrocytes, participants will be administered ferrous sulfate containing a stable isotope of iron (57Fe) orally in a randomized fashion following 2 weeks of administration of randomized study treatment. At Day 29 participants will be crossed over to receive Daprodustat in Treatment Period 2. At 2 weeks following initiation of dosing in Treatment Period 2, participants will again be administered ferrous sulfate containing the stable iron isotope (58Fe) orally. Participants will be advised to maintain use of oral iron supplementation (except ferric citrate) and acid-reducing agents (example: Histamine \[H2\] receptor antagonists, proton pump inhibitors, antacids) at a consistent dosage and frequency.
