Indications for ARANESP:
Anemia of chronic kidney disease (CKD), including patients on and not on dialysis. Chemotherapy-induced anemia in patients with non-myeloid malignancies.
Initiate only when hemoglobin (Hgb) <10g/dL. CKD (on dialysis): initially 0.45mcg/kg IV or SC once weekly; or 0.75mcg/kg IV or SC once every 2 weeks. Patients on hemodialysis: IV route is recommended. CKD (not on dialysis): initially 0.45mcg/kg SC or IV given once at 4 week intervals. Reduce or interrupt dose if Hgb >10g/dL (not on dialysis) or >11g/dL (on dialysis). Cancer: initially 2.25mcg/kg SC once weekly or 500mcg SC once every 3 weeks. Discontinue after completion of chemotherapy course. Use lowest dose sufficient to avoid red blood cell transfusion. Converting from epoetin alfa, and for dose adjustments: see full labeling.
Initiate only when hemoglobin (Hgb) <10g/dL. CKD: initially 0.45mcg/kg SC or IV once weekly; patients with CKD (not on dialysis): may also initiate at 0.75mcg/kg once every 2 weeks. Reduce or interrupt dose if Hgb >12g/dL. Cancer: not established.
Uncontrolled hypertension. Do not use in patients with pure red cell aplasia due to erythropoietin antibodies.
See full labeling. Increased risk of death, MI, stroke, venous thromboembolism, vascular thrombosis with Hgb >11g/dL in CKD. Increased mortality and/or risk of tumor progression or recurrence in breast, NSCLC, head and neck, lymphoid, cervical cancers. Evaluate serum iron, ferritin, transferrin saturation before and during therapy; most patients will need iron supplementation. Monitor hemoglobin weekly for 4 weeks after start and dose changes, until stabilized, then periodically; reduce dose if hemoglobin increases >1g/dL in any 2-week period. Monitor BP (reduce or withhold dose if hypertension occurs), folate, Vit. B12, renal function, electrolytes, fluid balance, and for premonitory neurological symptoms. Seizure, cardiovascular, or hematologic disorders. Infection, inflammation, malignancy, occult blood loss, bone marrow fibrosis may reduce effectiveness; consider other etiologies in treatment failures. Discontinue immediately if serious allergic, anaphylactic, or cutaneous reaction (eg, SJS/TEN) occurs. Adjust dialysis ℞ as needed. Latex allergy. Pregnancy (Cat.C). Nursing mothers.
Erythropoiesis stimulating protein.
CKD: hypertension, dyspnea, peripheral edema, cough, procedural hypotension. Cancer: abdominal pain, edema, thrombovascular events.
