Reduced use of erythropoiesis-stimulating agents and intravenous iron with ferric citrate: a managed care cost-offset model

Background Ferric citrate (FC) is a phosphate binder in development for the treatment of hyperphosphatemia in patients with end-stage renal disease (ESRD). In clinical trials, FC improved patient serum phosphorus levels and increased serum ferritin and percent transferrin saturation. Because nephrologists respond to increases in these iron measures by reducing intravenous (IV) iron and erythropoiesis-stimulating agent (ESA) doses, the decreased use of iron and ESA associated with FC may reduce costs.
