About this study

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 alfa 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, a cardiovascular composite safety endpoint (CSE) was defined for use in prospectively planned analyses which combined cardiovascular safety data from the four Phase 3 peginesatide 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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Participants with chronic renal failure on hemodialysis for ≥ 3 months prior to randomization.
  • On intravenous epoetin alfa maintenance therapy continuously prescribed for a minimum of 8 weeks prior to randomization.
  • Four consecutive hemoglobin values with a mean ≥ 10.0 and ≤ 12.0 g/dL during the screening period

Exclusion criteria

  • Females who are pregnant or breast-feeding.
  • Known intolerance to any erythropoiesis stimulating agent (ESA) or pegylated molecule or to all parenteral iron supplementation products.
  • Known bleeding or coagulation disorder.
  • Known hematologic disease or cause of anemia other than renal disease
  • Poorly controlled hypertension
  • Evidence of active malignancy within one year prior to randomization.
  • Temporary (untunneled) dialysis access catheter.
  • A scheduled kidney transplant
  • A scheduled surgery that may be expected to lead to significant blood loss.

Treatment and study plan

peginesatide

Drug

Participants received peginesatide by intravenous injection once every 4 weeks. The starting dose was based on the participant's total weekly epoetin alfa dose during the last week of the Screening Period; the first dose was administered one week after the last epoetin alfa dose. The dose was adjusted to maintain hemoglobin levels in a target range of 10.0-12.0 grams per deciliter (g/dL) and ± 1.5 g/dL from baseline during the Titration and Evaluation Periods, and 10.0-12.0 g/dL during the Long-Term Safety and Efficacy Period.

Epoetin alfa

Drug

Participants continued to receive commercially available epoetin alfa by intravenous injection, at the same starting dose and frequency as received during the last week of the Screening Period, with the first study dose of epoetin alfa administered after randomization at Week 0. The dose was adjusted to maintain hemoglobin levels in a target range of 10.0-12.0 g/dL and ± 1.5 g/dL from baseline during the Titration and Evaluation Periods, and 10.0-12.0 g/dL during the Long-Term Safety and Efficacy Period.

Other names: Epogen

Primary outcomes

  1. Mean Change in Hemoglobin Between Baseline and the Evaluation Period

    Time frame: Baseline and 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 outcomes

  1. Proportion of Participants Who Receive Red Blood Cell (RBC) Transfusions During the Titration and Evaluation Periods

    Time frame: Weeks 0 to 36

  2. 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)

    Time frame: Weeks 29 to 36
