    Abstract:
    Epoetin-beta is extremely useful as a drug for treating anemia in hemodialysis (HD) patients and is widely used for that purpose. The aim of this study was to determine whether once-weekly intravenous administration of epoetin-beta is as effective in maintaining hemoglobin (Hb) concentration as the same weekly dose administered 2 or 3 times per week as maintenance treatment of anemia in HD patients. The subjects were stable HD patients who had been receiving HD for at least 12 months. Using a fixed weekly dose of 3000 or 6000 IU of epoetin-beta, this study evaluated maintenance of improvement of anemia by comparing Hb concentration in the study period (once-weekly) with Hb concentration in the prestudy period (2 or 3 times per week). Of the 112 patients treated with epoetin-beta, 111 patients (full analysis set; 3000 IU, 52 patients; 6000 IU, 59 patients) were evaluated, after excluding one patient whose dose was changed immediately before study initiation. The change in the Hb concentration was maintained within +/-1.5 g/dL in 89.2% of patients (3000 IU, 88.5%; 6000 IU, 89.8%). The mean Hb concentration was 10.42 +/- 0.73 g/dL at study initiation and 10.14 +/- 1.00 g/dL at study completion. Adverse reactions occurred in 9.8% of patients (11 out of 112 patients). The main adverse reactions were malaise and increased blood pressure. Once-weekly intravenous administration of epoetin-beta is useful as maintenance treatment of anemia in HD patients and may be a treatment option.
