Overview

ℹ️

What is this medicine?

Aranesp is a medicine that helps your body make more red blood cells. It's used when your body isn't making enough red blood cells on its own, often due to kidney disease or certain cancer treatments. It works like a natural substance in your body called erythropoietin.

Pharmacology

πŸ”¬

Mechanism of Action

Darbepoetin alfa is an erythropoiesis-stimulating agent (ESA) that stimulates erythropoiesis by the same mechanism as endogenous erythropoietin. It interacts with the erythropoietin receptor on progenitor cells in the bone marrow to stimulate red blood cell production and differentiation. Darbepoetin alfa has a longer half-life than epoetin alfa due to increased glycosylation, allowing for less frequent dosing.
πŸ“Š

Pharmacokinetics

Absorption:

Bioavailability: Subcutaneous: Approximately 37% (CKD patients), 54% (cancer patients)
Tmax: Subcutaneous: Approximately 48 hours (CKD patients), 71 hours (cancer patients)
FoodEffect: Not applicable (parenteral administration)

Distribution:

Vd: Not extensively distributed into tissues; primarily confined to the vascular space.
ProteinBinding: Not extensively protein bound.
CnssPenetration: Limited

Elimination:

HalfLife: Intravenous: Approximately 21 hours (CKD patients). Subcutaneous: Approximately 49 hours (CKD patients), 46 hours (cancer patients).
Clearance: Clearance is primarily via receptor-mediated uptake and degradation.
ExcretionRoute: Primarily catabolism; minimal renal excretion of intact drug.
Unchanged: Less than 10% (renal excretion)
⏱️

Pharmacodynamics

OnsetOfAction: Increase in reticulocytes typically seen within 7-10 days; significant increase in hemoglobin usually within 2-6 weeks.
PeakEffect: Peak hemoglobin effect is typically observed several weeks after initiation of therapy and dose stabilization.
DurationOfAction: Due to its long half-life, effects persist for several days to weeks, allowing for weekly or bi-weekly dosing.

Safety & Warnings

⚠️

BLACK BOX WARNING

Increased risk of death, serious cardiovascular and thromboembolic events, and stroke in patients with chronic kidney disease (CKD) when ESAs are administered to target hemoglobin levels of greater than 11 g/dL. Increased risk of tumor progression or recurrence in patients with cancer. Use the lowest dose sufficient to avoid red blood cell transfusions.

Overdose Information

Overdose Symptoms:

  • Polycythemia (excessively high red blood cell count), which can lead to increased blood viscosity and thrombotic events (e.g., stroke, heart attack, deep vein thrombosis).

What to Do:

There is no specific antidote. Management should consist of supportive therapy aimed at reducing red blood cell count (e.g., phlebotomy) and managing complications. Call 1-800-222-1222 (Poison Control) or seek immediate medical attention.

Drug Interactions

Monitoring

πŸ”¬

Baseline Monitoring

Hemoglobin (Hb)

Rationale: To establish baseline and guide initial dosing.

Timing: Prior to initiation of therapy.

Iron status (Ferritin, Transferrin Saturation (TSAT))

Rationale: To ensure adequate iron stores for optimal erythropoiesis and response to darbepoetin alfa. Iron supplementation may be required.

Timing: Prior to initiation of therapy.

Blood Pressure (BP)

Rationale: To establish baseline and identify pre-existing hypertension, which can be exacerbated by ESA therapy.

Timing: Prior to initiation of therapy.

Complete Blood Count (CBC) with differential and platelet count

Rationale: To assess overall hematologic status and rule out other causes of anemia.

Timing: Prior to initiation of therapy.

πŸ“Š

Routine Monitoring

Hemoglobin (Hb)

Frequency: Weekly or bi-weekly until stable, then every 2-4 weeks.

Target: 10-11 g/dL (CKD); lowest Hb level to avoid transfusions (CIA). Avoid exceeding 11 g/dL (CKD) or 10 g/dL (CIA).

Action Threshold: If Hb increases by >1 g/dL in any 2-week period or exceeds target range, reduce dose. If Hb does not increase by 1 g/dL after 4 weeks of therapy, increase dose.

Blood Pressure (BP)

Frequency: Regularly, especially during the initial phase of therapy and dose adjustments.

Target: Individualized, maintain within patient's target range.

Action Threshold: If BP significantly increases or becomes difficult to control, consider dose reduction or discontinuation.

Iron status (Ferritin, TSAT)

Frequency: Monthly or every 3 months, or as clinically indicated.

Target: Ferritin >100 ng/mL (CKD), >200 ng/mL (CIA); TSAT >20%.

Action Threshold: If iron stores are low, initiate or increase iron supplementation.

πŸ‘οΈ

Symptom Monitoring

  • Symptoms of anemia (fatigue, shortness of breath, pallor)
  • Symptoms of hypertension (headache, dizziness, blurred vision)
  • Symptoms of thrombotic events (chest pain, shortness of breath, pain/swelling in leg, sudden numbness/weakness)
  • Symptoms of allergic reactions (rash, itching, swelling, severe dizziness, trouble breathing)
  • Symptoms of pure red cell aplasia (PRCA) (sudden worsening of anemia, lack of response to therapy)

Special Patient Groups

🀰

Pregnancy

Category C. There are no adequate and well-controlled studies in pregnant women. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Animal studies have shown adverse effects.

Trimester-Specific Risks:

First Trimester: Potential for adverse developmental effects observed in animal studies at high doses.
Second Trimester: Potential for adverse developmental effects observed in animal studies at high doses.
Third Trimester: Potential for adverse developmental effects observed in animal studies at high doses.
🀱

Lactation

It is unknown whether darbepoetin alfa is excreted in human milk. Caution should be exercised when Aranesp is administered to a nursing woman. Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for Aranesp and any potential adverse effects on the breastfed infant from Aranesp or from the underlying maternal condition.

Infant Risk: L3 (Moderately Safe) - Limited human data suggest that it is unlikely to be excreted into milk in clinically significant amounts. However, caution is advised.
πŸ‘Ά

Pediatric Use

Approved for anemia of CKD in pediatric patients aged 1 month and older. Dosing is weight-based. Safety and efficacy in pediatric patients with chemotherapy-induced anemia have not been established.

πŸ‘΄

Geriatric Use

No overall differences in safety or effectiveness were observed between elderly and younger patients. However, elderly patients may have a higher incidence of comorbidities (e.g., cardiovascular disease) that may increase the risk of adverse events associated with ESA therapy. Dose selection should be cautious, generally starting at the low end of the dosing range.

Clinical Information

πŸ’Ž

Clinical Pearls

  • Always ensure adequate iron stores (ferritin and TSAT) before and during darbepoetin alfa therapy, as iron deficiency is the most common cause of treatment failure.
  • Monitor hemoglobin levels closely and adjust dose to avoid exceeding target ranges, especially 11 g/dL in CKD patients, due to increased risks of cardiovascular events and mortality.
  • Blood pressure must be well-controlled before initiating therapy and monitored frequently during treatment, as hypertension is a common side effect.
  • Educate patients on the signs and symptoms of serious adverse events, particularly thrombotic events and severe hypertension, and when to seek immediate medical attention.
  • Darbepoetin alfa has a longer half-life than epoetin alfa, allowing for less frequent dosing (e.g., weekly or bi-weekly vs. thrice weekly for epoetin alfa).
πŸ”„

Alternative Therapies

  • Epoetin alfa (e.g., Epogen, Procrit, Retacrit - biosimilar)
  • Methoxy polyethylene glycol-epoetin beta (Mircera - another long-acting ESA)
  • Iron supplementation (oral or intravenous)
  • Red blood cell transfusions (for acute, severe anemia or when ESAs are contraindicated/ineffective)
πŸ’°

Cost & Coverage

Average Cost: Highly variable, typically several hundred to thousands of dollars per dose depending on strength. per prefilled syringe
Insurance Coverage: Tier 3 or 4 (Specialty Drug), often requires prior authorization and step therapy.
