Maintenance Switch in Dialysis Participants
Participants were from a prior Affymax peginesatide treatment study conducted in participants who were on dialysis and had been on Epoetin at study entry, and who were switched to peginesatide (NCT00434330). The median first dose at study start was 0.044 milligram per kilogram (mg/kg) with an interquartile range of 0.028 to 0.076 mg/kg. This group is categorized as "Maintenance Switch in Dialysis Participants" regardless of dialysis status at the start of or during this study.
Treatment Initiation in Non-Dialysis Participants
Participants were from a prior Affymax peginesatide treatment study conducted in participants who were not on dialysis and not on erythropoiesis stimulating agents (ESAs), and who received peginesatide (NCT00228436). The median first dose at study start was 0.024 mg/kg with an interquartile range of 0.017 to 0.035 mg/kg. This group is categorized as "Initiation of Treatment in Non-Dialysis Participants" regardless of dialysis status at the start of or during this study.
