Brief summary:
This single arm study will assess the efficacy, safety and tolerability of monthly intravenous Mircera for the maintenance of hemoglobin levels in dialysis patients with chronic renal disease, currently receiving epoetin alfa or beta. Patients will receive monthly intravenous injections of Mircera at a starting dose of 120, 200 or 360 micrograms/month, depending on the dose of epoetin alfa or beta 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.

Detailed description:

Arms:
arm 1: Eligible participants started RO0503821 (Continuous Erythropoietin Receptor Activator \[C.E.R.A\]) intravenously, at a dose of 120, 200 or 360 microgram (µg) every four weeks. The dose of C.E.R.A was based on the epoetin alfa or beta dose of\<8000, 8000-16000, or \>16000 international units (IU)/week, administered during the stability verification period (SVP) of 4 weeks. The SVP period was followed by dose titration period (DTP) of 16 weeks, efficacy evaluation period (EEP) of 8 weeks and long term safety period (LTSP) of 28 weeks

Interventions: intervention 1: methoxy polyethylene glycol-epoetin beta [Mircera]
Intervention descriptions: intervention 1: 120, 200 or 360 micrograms iv monthly (starting dose)
