From the Guidelines
Aranesp (darbepoetin alfa) is primarily used to treat anemia in patients with chronic kidney disease and in cancer patients receiving chemotherapy, by stimulating the bone marrow to produce more red blood cells, which helps increase hemoglobin levels and reduce the need for blood transfusions. The use of Aranesp is recommended as a treatment option for patients with chemotherapy-associated anemia and an Hb concentration that has decreased to less than 10 g/dL to decrease transfusions 1. For chronic kidney disease patients, typical starting doses range from 0.45 to 0.75 mcg/kg administered once weekly or once every two weeks, while cancer patients usually receive 2.25 mcg/kg weekly 1. Dosing is adjusted based on hemoglobin response, with target levels generally between 10-12 g/dL. Aranesp is administered as an injection either under the skin (subcutaneously) or into a vein (intravenously).
- Key considerations for Aranesp use include:
- Regular monitoring of hemoglobin levels to minimize risks
- Awareness of potential cardiovascular events and tumor progression in cancer patients
- Individualized dosing based on patient response and risk factors
- Consideration of alternative causes of anemia before initiating therapy Patients should be aware that Aranesp carries risks, including cardiovascular events and tumor progression in cancer patients, so regular monitoring of hemoglobin levels is essential 1. The medication works because it mimics erythropoietin, a natural hormone produced by the kidneys that signals the bone marrow to make red blood cells when oxygen levels in the blood are low.
- The decision to use Aranesp should be based on clinical judgment, consideration of the risks and benefits, and patient preferences, with careful evaluation of the potential for thromboembolic events, particularly in patients with multiple myeloma or other high-risk conditions 1.
From the FDA Drug Label
Aranesp is a prescription medicine used to treat anemia. People with anemia have a lower-than-normal number of RBCs Aranesp works like the human protein called erythropoietin to help your body make more RBCs. Aranesp is used to reduce or avoid the need for RBC transfusions. Aranesp may be used to treat anemia if it is caused by:
- Chronic kidney disease (you may or may not be on dialysis).
- Chemotherapy that will be used for at least two months after starting Aranesp.
Aranesp is used to treat anemia by stimulating the production of red blood cells. It is used in patients with chronic kidney disease or those undergoing chemotherapy. The goal of Aranesp treatment is to reduce the need for red blood cell transfusions. 2
From the Research
Uses of Aranesp
- Aranesp (darbepoetin alfa) is used to treat anemia associated with chronic kidney disease (CKD) 3, 4.
- It is also used to treat anemia in patients with chronic kidney disease who are not on dialysis 3, 5.
- Aranesp is used to maintain hemoglobin levels in patients with CKD who are on dialysis 3, 6.
- It is also approved for the treatment of anemia associated with myelosuppressive chemotherapy 7.
- Aranesp can be administered at extended intervals, such as every 1-4 weeks, due to its longer serum half-life compared to recombinant human erythropoietin (rhEPO) 3, 4, 6.
Administration and Dosage
- Aranesp can be administered subcutaneously or intravenously 3, 6.
- The dosage of Aranesp is titrated to maintain hemoglobin levels within a target range, typically between 10-12 g/dl 3, 5, 6.
- The dose of Aranesp may need to be adjusted based on the patient's response to treatment and their individual needs 3, 6.
Benefits and Safety
- Aranesp is generally well tolerated and has a safety profile similar to that of rhEPO 3, 4.
- The use of Aranesp can reduce the need for blood transfusions and improve quality of life for patients with anemia associated with CKD or chemotherapy 3, 7.
- However, high doses of Aranesp or targeting high hemoglobin levels may increase the risk of adverse events, such as stroke, vascular access thrombosis, and hypertension 5.
