Brief summary
The purpose of this study is to determine the efficacy and safety of Peginesatide Injection for the maintenance of anemia in patients with chronic renal failure who are on hemodialysis or do not require dialysis and who were previously treated with Darbepoetin Alfa.
Detailed description
Anemia, resulting primarily from insufficient production of erythropoietin to support erythropoiesis, is a common consequence of chronic renal failure. Both North America and Europe have established clinical practice guidelines for the treatment and hemoglobin targets in chronic renal failure/chronic kidney disease patients. These guidelines recommend the use of erythropoiesis-stimulating agents (ESAs). The benefits of ESA therapy include reduced fatigue, improved quality of life, decreased cardiovascular mortality risk and improved cardiovascular function. An increased risk of death and serious cardiovascular and thromboembolic events, including myocardial infarction, stroke, congestive heart failure, and hemodialysis graft occlusion have been observed in controlled clinical trials of ESAs when administered to target hemoglobin levels of ≥13.5 g/dL. The vast majority of patients receiving hemodialysis receive ESA therapy to treat their anemia and most patients begin ESA therapy prior to any requirement for dialysis. Anemia of chronic renal failure is due to several factors, primarily the inability of the diseased kidneys to produce adequate amounts of endogenous erythropoietin. Ancillary factors also include the shortened lifespan of red blood cells, iron and other nutritional deficiencies, infection, and inflammation. The prevalence of anemia increases with progressive deterioration of renal function, and affects more than 90% of patients with chronic renal failure Stage 5 (End Stage Renal Disease). Anemia is associated with increased mortality, increased likelihood of hospitalization, reduced cognitive function and exercise capacity, increased left ventricular hypertrophy and heart failure. Treatment of anemia reduces morbidity and mortality risks and may improve quality of life. Erythropoiesis stimulating agents have been established as a treatment for anemia in chronic renal failure participants, and have improved the management of anemia over alternatives such as transfusion. Peginesatide (hematide) is a parenteral formulation being developed for the correction of anemia in patients with chronic renal failure, and 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. Participants in this study received variable doses of peginesatide injection once every four weeks. Total commitment time for this study was about 30 weeks.
Interventions
Peginesatide 0.04 to 0.16 mg/kg, subcutaneous or intravenous injection, once every 4 weeks for up to 24 weeks. Initial dose based on patient's previous total weekly darbepoetin alfa dose, and thereafter could be adjusted to maintain hemoglobin values in the target range of 10 to 12 g/dL and ±1.5 g/dL from Baseline.
