Trial Outcomes & Findings for Safety & Efficacy of Peginesatide for Treatment of Anemia in Participants on Dialysis Not Receiving an ESA (NCT NCT00680043)

NCT ID: NCT00680043

Last Updated: 2012-06-29

Results Overview

The baseline hemoglobin value is defined as the mean of the two most recent hemoglobin values taken prior to the day of randomization plus the value obtained on the day of randomization prior to Dose 1. The mean hemoglobin during the Evaluation period for each participant is calculated as the mean of the available hemoglobin values during Study Weeks 21 through 28.

Measure
Peginesatide 0.04 mg/kg
Participants received peginesatide by intravenous injection once every 4 weeks at the starting dose of 0.04 milligram per kilogram (mg/kg); the dose was adjusted throughout the study to maintain a hemoglobin target range of 11.0-12.0 grams per deciliter (g/dL).
Peginesatide 0.08 mg/kg
Participants received peginesatide by intravenous injection once every 4 weeks at the starting dose of 0.08 mg/kg; the dose was adjusted throughout the study to maintain a hemoglobin target range of 11.0-12.0 g/dL.
Epoetin Alfa
Participants received Epoetin alfa by intravenous injection three times a week at the starting dose of 50 Units/kg; the dose was adjusted throughout the study to maintain a hemoglobin target range of 11.0-12.0 g/dL.
