Inclusion criteria
* Patients who have been receiving hemodialysis 3 times a week for at least 12 weeks before registration * Patients aged ≥ 20 years at the time of obtaining consent * Patients who have been receiving a rHuEPO preparation at least once a week for at least 8 weeks before registration * Within 4 weeks before registration, patients who have been receiving a rHuEPO preparation 750IU (3 times a week), 1,500IU (twice a week (1st and 2nd hemodialysis day of the week, or1st and 3rd hemodialysis day of the week)), 1,500IU (3 times a week), or 3,000IU (twice a week (1st and 2nd hemodialysis day of the week, or1st and 3rd hemodialysis day of the week)), and patients who have not change dosage and administration. * Patients whose pre-dialysis Hb concentrations has been between ≥ 9.0 g/dL and ≤12.0 g/dL and mean value of pre-dialysis Hb concentrations has been between ≥ 9.5 g/dL and ≤11.5 g/dL determined at the beginning of each week within 8 weeks before registration * Patients whose transferrin saturation has been ≥ 20 % or ferritin has been ≥ 100ng/mL at any time point within 8 weeks before registration
Exclusion criteria
