About Peginesatide

Peginesatide is a novel synthetic, PEGylated peptidic compound that binds to and activates the erythropoietin receptor and thus acts as an erythropoesis stimulating agent or ESA.  

Affymax and Takeda are collaborating on the development of peginesatide and plan to co-commercialize the product if approved in the United States.  Phase 3 clinical trials were designed to investigate the potential for peginesatide to treat anemia associated with chronic renal failure.  A New Drug Application submission for peginesatide is anticipated in the second quarter of 2011.  The product, upon approval, will be commercialized outside the United States by Takeda.

 

About Anemia in Chronic Renal Failure (CRF)

Anemia is a common complication in chronic kidney disease (also referred to as CKD or chronic renal failure), because the impaired kidneys are not able to produce enough erythropoietin, the hormone that promotes the production of oxygen-carrying red blood cells.4 Research has shown that anemia impacts the overall health and well being of CKD and dialysis patients and is associated with increased rates of hospitalization and mortality.5  In severe or prolonged cases of anemia, the lack of oxygen in the blood can cause serious and sometimes fatal damage to the heart and other organs.6,7   

Anemia often develops in the early stages of CKD and worsens as patients progress toward total kidney failure and need dialysis (also referred to as end-stage renal disease).4 ESAs, which stimulate red blood cell production, are commonly prescribed to treat anemia in chronic renal failure (CRF).6,7  According to the Center for Medicaid Services, more than 95 percent of patients on dialysis in the U.S. are currently receiving ESA treatment for anemia in CRF.8
