Study Summary

Daprodustat administration has the potential, by virtue of increasing hypoxia-inducible factor (HIF) levels, to increase oral iron absorption and incorporation into hemoglobin (Hgb). Therefore, the purpose of this study is to compare the effect of daprodustat to rhEPO (i.e., epoetin alfa or darbepoetin alfa) on non-heme oral iron absorption using stable isotopic iron (57Fe and 58Fe) by measuring incorporation of iron in erythrocytes. This study will be a randomized, repeat dose, open label, two period cross-over study in adult, male and female participants with anemia associated with chronic kidney disease who are not on dialysis currently treated with stable doses less than or equal to (\<=) 50 percent (%) change in 4-weekly dose) for at least 8 weeks prior to and including the screening period, of rhEPO (i.e., epoetin alfa or darbepoetin alfa). Sufficient participants will be enrolled such that at least 12 participants comprise the Evaluable Population. The study will compare the fractional iron absorption between treatment arms (daprodustat and rhEPO \[i.e., epoetin alfa or darbepoetin alfa\]) and will evaluate the difference is equal/not equal to zero.

Primary Outcome

Blood samples were collected at indicated time points for analysis of fractional oral iron absorption following treatment with Daprodustat and rhEPO. Adjusted mean and 95 percent (%) confidence interval (CI) has been presented.

Interventions

  • DRUG Daprodustat
  • DRUG rhEPO
