Title: An Open Label Randomised Controlled Study to Compare the Efficacy, Safety and Tolerability of Once-monthly Administration of Subcutaneous Mircera Versus Darboepoetin Alfa for the Maintenance of Haemoglobin Levels in Renal Transplant Recipients With Chronic Renal Anaemia.
Brief Summary: This two arm study will compare the efficacy and safety of subcutaneous Mircera versus darbepoetin alfa for the maintenance of hemoglobin levels in kidney transplant recipients with chronic renal anemia. Patients currently receiving maintenance treatment with darbepoetin alfa will be randomized either to receive 4-weekly injections of Mircera with a starting dose (120, 200 or 360 micrograms subcutaneously) derived from the dose of darbepoetin alfa they were receiving in the 2 weeks preceding study start, or to stay on 2-weekly darbepoetin alfa therapy. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.


Options:
A: Inclusion Criteria:

1. Chronic renal failure with an estimated glomerular filtration rate \< 60 milliliters per minute per 1.73 m\^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.
B: Inclusion Criteria:

* blood transfusion within the last 3 months;
* need for dialysis expected in the next 6 months;
* administration of another investigational drug within 30 days preceding study start, or during the study.
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:
