Treatment Groups

Study Objectives

2 intervention groups are designated in this study

This study does not include a placebo group

Treatment Groups

Group I

Active Comparator

Eligible participants will be administered with darbepoetin alfa IV, every week or every 2 weeks during Weeks 1 through 52.

Group II

Experimental

Eligible participants will be administered with RO0503821 (\[methoxy polyethylene glycol-epoetin beta\] {Mircera}) intravenously (IV), every 2 weeks during Weeks 1 through 52. The starting dose of RO0503821 (60, 100, or 180 micro gram \[µg\]) was based on the dose of darbepoetin alfa at the time of randomization (\< 40, 40 to 80, or \> 80 µg per week, respectively).
