Overview
Brief Summary
This single arm study will assess the efficacy and safety of Mircera when administered once monthly, subcutaneously or intravenously, for the maintenance of hemoglobin levels in dialysis patients with chronic renal anemia. Patients currently receiving maintenance treatment with epoetin alfa will receive monthly injections of Mircera with a starting dose (120, 200 or 360 micrograms) derived from the dose of epoetin alfa they were receiving 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.

Eligibility Criteria
Inclusion Criteria
- •adult patients, \>=18 years of age;
- •chronic renal anemia;
- •hemodialysis or peritoneal dialysis, with same mode of dialysis for \>=3 months before and throughout screening period;
- •stable maintenance epoetin alfa therapy for past 2 months.

Arms & Interventions
C.E.R.A
Participants with chronic renal anaemia who were on dialysis and previously treated with intravenous (IV) or subcutaneous (SC) epoetin alfa, epoetin beta or darbepoetin alfa received monthly treatment with Continuous Erythropoietin Receptor Activator (C.E.R.A.) (methoxy polyethylene glycol-epoetin beta \[Mircera\]). The initial dose of C.E.R.A. was based on the last dose of the previous Erythropoiesis Stimulating Agent (ESA); 120, 200, or 360 micrograms (mcg) C.E.R.A., IV or SC, every 4 weeks for 48 weeks.
Intervention: methoxy polyethylene glycol-epoetin beta [Mircera]
Outcomes
Primary Outcomes
Percentage of Participants Maintaining Their Mean Hb Concentration Within ±1.0 Gram/Deciliter of Their Reference Hb and Between 10.5 and 12.5 Gram/Deciliter
Time Frame: EEP (Week 16 to 24)
The haemoglobin (Hb) levels were recorded for each participant at enrollment and at different time points during the study up to Week 48. The reference Hb value was defined on the basis of individual participant's all assessments at Weeks -4, -3, -2, -1 and 0. The Hb value on the first day of first dose (Week 0) was included in the calculation, as this assessment was performed before the first dose was given. The percentage of participants maintaining their mean Hb concentration within +/-1.0 gram/deciliter (g/dL) of their reference Hb and between 10.5 and 12.5 g/dL are reported for efficacy evaluation period (EEP). Efficacy evaluation period was from Week 16 to Week 24 after completion of 16-week dose titration period (DTP).
