EPOGEN® (Epoetin alfa) is indicated for the treatment of anemia in patients with chronic renal failure (CRF) on dialysis. EPOGEN® is indicated to elevate or maintain the red blood cell (RBC) level and to decrease the need for transfusions in these patients. Important Safety Information, including Boxed WARNINGS EPOGEN® (Epoetin alfa) is contraindicated in patients with uncontrolled hypertension. Patients with chronic renal failure (CRF) experienced greater risks for death and serious cardiovascular events when administered erythropoiesis-stimulating agents (ESAs) to target higher versus lower hemoglobin levels in two clinical studies. Patients with CRF and an insufficient hemoglobin response to ESA therapy may be at even greater risk for cardiovascular events and mortality than other patients. These events included myocardial infarction, stroke, congestive heart failure, and hemodialysis vascular access thrombosis. A rate of hemoglobin rise of > 1 g/dL over 2 weeks may contribute to these risks. Seizures have occurred in patients with CRF participating in EPOGEN® clinical trials. Cases of pure red cell aplasia (PRCA) and of severe anemia, with or without other cytopenias, associated with neutralizing antibodies to erythropoietin have been reported in patients treated with EPOGEN®. This has been reported predominantly in patients with CRF receiving ESAs by subcutaneous administration. PRCA has also been reported in patients receiving ESAs while undergoing treatment for hepatitis C with interferon and ribavirin. A sudden loss of response to EPOGEN®, accompanied by severe anemia and low reticulocyte count, should be evaluated. If anti-erythropoietin antibody-associated anemia is suspected, withhold EPOGEN® and other ESAs. EPOGEN® should be permanently discontinued in patients with antibody-mediated anemia. Patients should not be switched to other ESAs as antibodies may cross-react. The most commonly reported side effects in clinical trials were hypertension, headache, arthralgias, and nausea. ![]() |
