Study Notes
Neulasta Indications and Administration
- Neulasta® decreases the incidence of infection, specifically febrile neutropenia, in non-myeloid malignancy patients undergoing myelosuppressive therapies.
- It is not meant for mobilizing peripheral blood progenitor cells for stem cell transplantation.
- Administer a single subcutaneous injection of 6 mg once per chemotherapy cycle.
- Do not administer Neulasta® between 14 days before and 24 hours after cytotoxic chemotherapy.
Neulasta Drug Supply and Usage
- Supplied in a prefilled single-dose syringe containing 6 mg of pegfilgrastim and a 27-gauge, ½-inch needle with an UltraSafe® Needle Guard.
- The syringe contains 0.64 mL of solution, delivering 6 mg/0.6 mL when used with the on-body injector (OBI).
- The OBI will deliver Neulasta® approximately 27 hours after application for a duration of 45 minutes.
- The prefilled syringe in the Neulasta® Onpro® kit is exclusively for use with the OBI.
Contraindications and Warnings
- Neulasta® is contraindicated for patients with a history of severe allergic reactions to pegfilgrastim or filgrastim, including anaphylaxis.
- Warnings include risks of splenic rupture, Acute Respiratory Distress Syndrome (ARDS), serious allergic reactions, and potential stimulatory effects on malignant cells.
- Caution advised for use in patients with sickle cell disorders and those experiencing glomerulonephritis.
Adverse Reactions and Efficacy
- The most common adverse reactions occurring in more than 5% of patients include bone pain and extremity pain.
- No significant safety or effectiveness differences noted between patients aged 65 and older and younger patients receiving Neulasta®.
- Neulasta® has a half-life ranging from 15 to 80 hours after subcutaneous injection.
Pregnancy and Mechanism of Action
- Classified as Pregnancy Category C; benefits must justify risks during pregnancy with no well-controlled studies available.
- A pregnancy registry exists for women treated with Neulasta® who become pregnant.
- Mechanism of action involves pegfilgrastim acting as a colony-stimulating factor for hematopoietic cells, stimulating proliferation, differentiation, commitment, and functional activation.
- Neutrophil receptor binding is a key factor in the pharmacokinetics and clearance of pegfilgrastim, with serum clearance linked to neutrophil count.
