Summary

It is the investigators hypothesis that participants treated with Ferric Citrate (FC) during the non-dialysis CKD stage (4/5) with sufficient duration prior to initiating RRT, will result in improved biochemical control of anemia (Hb, TSAT) and mineral metabolism (P, FGF23) and furthermore, will result in a reduced need for ESA and intravenous iron. The investigators further hypothesize that effective treatment of anemia and mineral metabolism with FC in the pre-dialysis and transition period will result in improved physical functioning, reduced hospitalization and reduced total cost of care when compared to participants receiving contemporaneously provided standard of care therapy.

Eligible Conditions
  • Iron-Deficiency Anemia
  • Kidney Failure
  • Chronic Kidney Disease
  • High Phosphate Levels

Trial Design

2Treatment groups
Active Control
Group I: Ferric CitrateActive Control1 Intervention
Ferric citrate (FC) will be supplied as tablets containing 210mg of ferric iron (as 1g ferric citrate) to those subjects randomized to FC. These participants will be initiated on study drug with a fixed dose of FC beginning with 2 tablet per meal.
Group II: Standard of Care (SOC)Active Control1 Intervention
Participants may receive open-label, non-FC phosphate binders at the discretion of their treating physician. During the Dialysis Period, dose of phosphate binders, use of ESA, intravenous iron and blood transfusions will be at the discretion of the primary treating nephrologist. Participants assigned to the SOC treatment arm may not receive FC at any point during the study.
