Title: An Open-label, Multicenter, Randomized Study to Determine Dose Conversion Factors at Different Frequencies of Administration After Switching From Maintenance Treatment With Subcutaneous Epoetin Alfa or Beta to Maintenance Treatment With Subcutaneous RO0503821 in Dialysis Patients With Chronic Renal Anemia
Brief Summary: This study will determine the appropriate dose and frequency of administration of sc Mircera maintenance therapy in dialysis patients with chronic renal anemia who were previously receiving sc epoetin alfa or beta. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.


Options:
A: Inclusion Criteria

1. Participants with chronic renal failure on hemodialysis for ≥ 3 months prior to randomization.
2. On intravenous epoetin alfa maintenance therapy continuously prescribed for a minimum of 8 weeks prior to randomization.
3. Four consecutive hemoglobin values with a mean ≥ 10.0 and ≤ 12.0 g/dL during the screening period

Exclusion Criteria

1. Females who are pregnant or breast-feeding.
2. Known intolerance to any erythropoiesis stimulating agent (ESA) or pegylated molecule or to all parenteral iron supplementation products.
3. Known bleeding or coagulation disorder.
4. Known hematologic disease or cause of anemia other than renal disease
5. Poorly controlled hypertension
6. Evidence of active malignancy within one year prior to randomization.
7. Temporary (untunneled) dialysis access catheter.
8. A scheduled kidney transplant
9. A scheduled surgery that may be expected to lead to significant blood loss.
B: Inclusion Criteria:

* adult patients \>=18 years of age;
* chronic renal anemia;
* on dialysis (hemodialysis or peritoneal dialysis) therapy for at least 3 months;
* receiving sc epoetin alfa or beta for at least 3 months prior to the run-in period.

Exclusion Criteria:

* women who are pregnant, breastfeeding or using unreliable birth control methods;
* use of any investigational drug within 30 days preceding the run-in phase, or during the run-in or study treatment period.
C: Inclusion Criteria:

1. Chronic renal failure with an estimated glomerular filtration rate \< 60 milliliter per minute per 1.73m\^2 and not expected to begin dialysis for at least 12 weeks.
2. Two consecutive hemoglobin values ≥ 8.0 g/dL and \< 11.0 g/dL within 4 weeks prior to randomization.

Exclusion Criteria:

1. Females who are pregnant or breast-feeding.
2. Treatment with an ESA in the 12 weeks prior to randomization.
3. Known intolerance to any ESA, parenteral iron supplementation, or pegylated molecule.
4. Prior chronic hemodialysis or chronic peritoneal dialysis treatment.
5. Known bleeding or coagulation disorder.
6. Known hematologic disease or cause of anemia other than renal disease
7. Poorly controlled hypertension
8. Evidence of active malignancy within one year prior to randomization.
9. A scheduled kidney transplant
D: Inclusion Criteria:

* adult patients, \>=18 years of age;
* chronic renal anemia;
* hemodialysis 3 times weekly for \>=12 weeks before screening, and during screening/baseline period;
* receiving darbepoetin alfa maintenance therapy for \>=8 weeks before screening, and during screening/baseline period.

Exclusion Criteria:

* overt gastrointestinal bleeding within 8 weeks before screening or during screening/baseline period;
* transfusion of red blood cells within 8 weeks before screening or during screening/baseline period;
* active malignancy;
