This single arm study will assess the efficacy and safety of subcutaneous Mircera for maintenance of hemoglobin levels in pre-dialysis patients with chronic renal anemia. Patients currently receiving maintenance treatment with subcutaneous darbepoetin alfa will receive monthly subcutaneous injections of Mircera with the starting dose (120, 200 or 360 micrograms) derived from the dose of darbepoetin alfa or epoetin alfa in the week preceding study start. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
