Extension Study to Evaluate Safety and Tolerability of Peginesatide for Long-Term Treatment of Anemia in Participants With CKD

Participants received the same initial peginesatide dose as was administered at the end of the previous peginesatide treatment study (NCT00228449) in which the participant was enrolled. The median first dose at study start was 0.087 milligram per kilogram (mg/kg) with an interquartile range of 0.064 to 0.123 mg/kg. Each participant was to receive peginesatide as an injection administered intravenously once every 4 weeks for approximately 54 months in this trial.
