Trial Outcomes & Findings for Safety & Efficacy of Peginesatide for the Treatment of Anemia in Participants With Chronic Renal Failure Not on Dialysis (NCT NCT00598273)

NCT ID: NCT00598273

Last Updated: 2013-02-12

Results Overview

The baseline hemoglobin value is defined as the mean of three hemoglobin values: the two most recent hemoglobin values taken prior to the day of randomization and the value obtained on the day of randomization. The mean hemoglobin during the Evaluation Period for each participant is calculated as the mean of the available hemoglobin values during Study Weeks 25 through 36.

Measure
Peginesatide 0.025 mg/kg
Participants received peginesatide by subcutaneous injection once every 4 weeks. The starting dose was 0.025 milligram per kilogram (mg/kg) and was adjusted throughout the study to maintain a hemoglobin target range of 11.0-12.0 grams per deciliter (g/dL).
Peginesatide 0.04 mg/kg
Participants received peginesatide by subcutaneous injection once every 4 weeks. The starting dose was 0.04 mg/kg and was adjusted throughout the study to maintain a hemoglobin target range of 11.0-12.0 g/dL.
Darbepoetin Alfa
Participants received a starting dose of 0.75 microgram per kilogram (mcg/kg) administered by subcutaneous injection once every 2 weeks, as prescribed. The dose was adjusted throughout the study to maintain a hemoglobin target range of 11.0-12.0 g/dL.
