ARANESP

DARBEPOETIN ALFA
Oncology Approved 2001-09-17

Aranesp (darbepoetin alfa) is an erythropoiesis-stimulating agent indicated for the treatment of anemia associated with chronic kidney disease in both dialysis and non-dialysis patients. It is also used to treat anemia in patients with non-myeloid malignancies receiving concomitant myelosuppressive chemotherapy where at least two additional months of treatment are planned. The medication is not indicated for use as a substitute for red blood cell transfusions when immediate correction of anemia is required. Additionally, Aranesp has not been demonstrated to improve quality of life, fatigue, or patient well-being.

How ARANESP Works

Aranesp acts as an erythropoiesis-stimulating agent to increase the production of red blood cells. It functions by stimulating erythropoiesis through the same biological mechanism as endogenous erythropoietin. By activating this process, the drug helps elevate red blood cell levels to treat anemia caused by kidney disease or chemotherapy.
