Randomised controlled trial of maintaining low serum ferritin levels in patients receiving darbepoetin (Aranesp®)

Study hypothesis Haemodialysis patients are currently treated with intravenous iron and subcutaneous recombinant human erythropoietin to treat anaemia associated with end-stage renal failure. To ensure optimum erythropoiesis, iron stores, as judged by serum ferritin, are kept above the normal range. Recently, a novel form of modified erythropoietin, darbopoetin alfa (Aranesp®), has been licensed for use. This has a longer duration of action and needs to be administered only once a week. Consequently, it does not result in a burst of erythropoietic activity. It is assumed that the prolonged erythropoiesis does not result in peaks of iron utilisation, and so requires lower levels of available iron, which can be replenished from iron stores sufficiently rapidly to continue to support erythropoiesis. We propose to study the effect of maintaining "normal" ferritin levels compared with "supranormal" ferritin in stable haemodialysis patients receiving Aranesp®.
