Brief Summary

The purpose of this study was to evaluate the safety and efficacy of peginesatide in the maintenance treatment of anemia in participants on dialysis.

Detailed Description

Anemia associated with chronic kidney disease is due to several factors, primarily the inability of the diseased kidneys to produce adequate amounts of endogenous erythropoietin. Ancillary factors include the shortened lifespan of red blood cells, iron and other nutritional deficiencies, infection, and inflammation. The presence and severity of anemia are related to the duration and extent of kidney failure. Anemia is associated with increased mortality, increased likelihood of hospitalization, reduced cognitive function, and increased left ventricular hypertrophy and heart failure.

Erythropoiesis stimulating agents (ESAs) have been established as a treatment for anemia in chronic renal failure subjects, and have improved the management of anemia over alternatives such as transfusion. Peginesatide is a parenteral formulation developed for the treatment of anemia in patients with chronic kidney disease. Peginesatide binds to and activates the human erythropoietin receptor and stimulates erythropoiesis in human red cell precursors in a manner similar to other known erythropoiesis-stimulating agents.

Eligible participants were randomized in a 2:1 ratio to peginesatide administered once every 4 weeks or to continued treatment with epoetin administered 1-3 times each week, respectively. Total commitment time for this study was 4 weeks of screening followed by a minimum of 52 weeks of study treatment.

To evaluate the cardiovascular safety of peginesatide injection, a composite safety endpoint (CSE) was defined for use in prospectively planned analyses which combined cardiovascular safety data from the four Phase 3 peginesatide injection studies (NCT00598273, NCT00597753, NCT00598442, and NCT00597584). The CSE consisted of six events: death, stroke, myocardial infarction, and serious adverse events of congestive heart failure, unstable angina, and arrhythmia. An independent Event Review Committee (ERC) was used to provide blinded adjudication of potential CSE events.

Primary Outcome Measures
NameTimeMethod
Mean Change in Hemoglobin Between Baseline and the Evaluation PeriodBaseline to Weeks 29-36

The baseline hemoglobin value is defined as the mean of five hemoglobin values: the four 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 29 through 36.

Secondary Outcome Measures
NameTimeMethod
Proportion of Participants Who Receive Red Blood Cell (RBC) Transfusions During the Titration and Evaluation PeriodsWeeks 0 to 36
Proportion of Participants Whose Mean Hemoglobin Level During the Evaluation Period is Within the Target Range of 10.0 - 12.0 Grams Per Deciliter (g/dL)Weeks 29 to 36
