Overview
Brief Summary
This single arm study will assess the efficacy, safety and tolerability of once monthly administration of subcutaneous Mircera for the maintenance of hemoglobin levels in dialysis patients with chronic renal anemia. Patients will receive subcutaneous Mircera at a starting dose of 120, 200 or 360 micrograms every 4 weeks, calculated from the last weekly dose of epoetin or darbepoetin alfa previously administered. Subsequent doses will be adjusted to maintain hemoglobin levels within the target range. Treatment duration is 56 weeks, and the target sample size is 200 individuals.

Eligibility Criteria
Inclusion Criteria
- •adult patients \>=18 years of age;
- •chronic renal anemia;
- •regular long-term hemodialysis or peritoneal dialysis, with same mode of dialysis for \>=3 months;
- •continuous iv maintenance epoetin alfa therapy with same dosing interval during previous 2 months.

Arms & Interventions
C.E.R.A.
Eligible participants will be administered continuous erythropoietin receptor activator (C.E.R.A.\[Mircera\]) intravenously (IV) every 4 weeks for 44 weeks. The starting dose of 120, 200, or 360 micrograms (mcg) will be based on the dose of epoetin alfa or beta administered in the week preceding the switch to C.E.R.A. Subsequent doses will be adjusted to maintain the individual participant's hemoglobin (Hb) within a range of +/- 1.0 grams per deciliter (g/dL) of the reference hemoglobin (Hb) concentration and between 10.50 and 12.50 g/dL.
Intervention: methoxy polyethylene glycol-epoetin beta [Mircera]
Outcomes
Primary Outcomes
Percentage of Participants Maintaining Mean Hemoglobin Concentration Within +/- 1 g/dL of Their Reference Hb and Between 10.5 and 12.5 g/dL During Efficacy Evaluation Period
Time Frame: EEP (Week 17 to Week 24)
The percentage of participants who maintained their mean Hb concentration within +/- 1 g/dL of their reference Hb and between 10.5 and 12.5 g/dL during the Efficacy Evaluation Period (EEP) is reported. The EEP was from Week 17 to Week 24. The reference Hb was calculated from the mean of Hb concentrations based upon the Hb assessments at Weeks -4, -3, -2, -1, and 0.

- Number of Participants With Any Adverse Events or Serious Adverse Events(Up to Week 52)
- Mean Hematocrit Levels Over Time(Baseline (Week 0) and Weeks 8, 16, 24, 32, 40, and 48)
- Mean Albumin Levels Over Time(Baseline (Week 0) and Weeks 8, 16, 24, 32, 40, and 48)
- Mean Change From Baseline in Weight Over Time(Week 16 and Week 48)
- Percentage of Participants Requiring Any Dose Adjustment During DTP and EEP(DTP (Week 1 to Week 16) and EEP (Week 17 to Week 24))
- Mean Hemoglobin Levels Over Time(Baseline (Week 0) and Weeks 8, 16, 24, 32, 40, and 48)
- Mean Change in Hemoglobin Concentration Between Reference (Stability Verification Period) and the Efficacy Evaluation Period(SVP (Weeks -3, -2, -1) and EEP (Week 17 to Week 24))
- Mean Time Spent By Participants With Hemoglobin Range of 10.5-12.5 g/dL During the EEP(EEP (Week 17 to Week 24))
