Safety & Efficacy of Peginesatide for Treatment of Anemia in Participants on Dialysis Not Receiving an ESA
AFX01-15: A Phase 2, Randomized, Active-controlled, Open-label, Multi-center Study of the Safety and Efficacy of Peginesatide for the Correction of Anemia in Patients With Chronic Renal Failure (CRF) Undergoing Hemodialysis and Not on Erythropoiesis Stimulating Agent (ESA) Treatment

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 equal proportions to two peginesatide treatment regimens, in which participants received peginesatide once every 4 weeks, and one control, epoetin alfa, treatment regimen, in which participants received epoetin alfa three times per week. Total commitment time of this study was a 4 week screening period followed by a minimum of 7 months of treatment.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: 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).
Other Names:
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.

Active Comparator: Epoetin Alfa
|

Measure Description |
Time Frame |
---|---|---|
Mean Change in Hemoglobin Between Baseline and the Evaluation Period
Time Frame: Baseline and Weeks 21-28
|
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.

Proportion of Participants Achieving Hemoglobin Response During the Correction and Evaluation Periods
Time Frame: Weeks 1 to 28
|
A hemoglobin response is defined as a hemoglobin increase of ≥ 1.0 g/dL above baseline and a hemoglobin ≥ 11.0 g/dL without RBC or whole blood transfusion during the previous 8 weeks.
