Iron stores assuring optimal efficacy/safety for erythropoiesis are unknown in the dialysis population. Using multicenter trial data, we related safety profiles, erythropoiesis-stimulating agent (ESA), and intravenous iron dosing to achieved iron stores in 441 subjects randomized 2 : 1 to ferric citrate or active control as their phosphate binder over 52 weeks. Intravenous iron was given at each site's discretion if ferritin ≤ 1,000 ng/mL and transferrin saturation ≤ 30%.

View Article and Find Full Text PDFFerric citrate (FC) is a phosphate binder with shown efficacy and additional effects on iron stores and use of intravenous (iv) iron and erythropoiesis-stimulating agents (ESAs). We provide detailed analyses of changes in iron/hematologic parameters and iv iron/ESA use at time points throughout the active control period of a phase 3 international randomized clinical trial. In all, 441 subjects were randomized (292 to FC and 149 to sevelamer carbonate and/or calcium acetate [active control (AC)]) and followed for 52 weeks.

Background: Ferric citrate (FC) is a new phosphorus binder shown to increase serum iron stores while reducing intravenous iron and erythropoiesis-stimulating agent usage. Such reductions could lower hospitalization rates and associated costs.
Methods: Hospitalizations during a Phase III trial were compared between FC and active control (AC).

Ferric citrate (Zerenex™, Keryx Biopharmaceuticals, Inc.), a phosphate binder drug candidate, recently completed a Phase III program confirming efficacy and demonstrating safety when used to treat hyperphosphatemia in patients with end-stage renal disease. Results of these trials demonstrate that ferric citrate effectively controls serum phosphorus and is well tolerated.
