Important Safety Information
Do not administer Neulasta® to patients with a history of serious allergic reactions to pegfilgrastim or filgrastim.
Splenic rupture, including fatal cases, can occur following the administration of Neulasta®. Evaluate for an enlarged spleen or splenic rupture in patients who report left upper abdominal or shoulder pain after receiving Neulasta®.
Acute Respiratory Distress Syndrome
Acute respiratory distress syndrome (ARDS) can occur in patients receiving Neulasta®. Evaluate patients who develop fever and lung infiltrates or respiratory distress after receiving Neulasta® for ARDS. Discontinue Neulasta® in patients with ARDS.
Serious Allergic Reactions
Serious allergic reactions, including anaphylaxis, can occur in patients receiving Neulasta®. The majority of reported events occurred upon initial exposure. Allergic reactions, including anaphylaxis, can recur within days after the discontinuation of initial anti-allergic treatment. Permanently discontinue Neulasta® in patients with serious allergic reactions.
Allergies to Acrylics
The On‑body Injector for Neulasta® uses acrylic adhesive. For patients who have reactions to acrylic adhesives, use of this product may result in a significant reaction.
Use in Patients with Sickle Cell Disorders
Severe sickle cell crises can occur in patients with sickle cell disorders receiving Neulasta®. Severe and sometimes fatal sickle cell crises can occur in patients with sickle cell disorders receiving filgrastim, the parent compound of pegfilgrastim.
Glomerulonephritis has been reported in patients receiving Neulasta®. The diagnoses were based upon azotemia, hematuria (microscopic and macroscopic), proteinuria, and renal biopsy. Generally, events of glomerulonephritis resolved after withdrawal of Neulasta®. If glomerulonephritis is suspected, evaluate for cause. If causality is likely, consider dose-reduction or interruption of Neulasta®.
White blood cell counts of 100 x 109/L or greater have been observed in patients receiving pegfilgrastim. Monitoring of CBCs during pegfilgrastim therapy is recommended.
Capillary Leak Syndrome
Capillary leak syndrome has been reported after granulocyte colony-stimulating factor (G-CSF) administration, including Neulasta®, and is characterized by hypotension, hypoalbuminemia, edema, and hemoconcentration. Episodes vary in frequency, severity and may be life-threatening if treatment is delayed. Patients who develop symptoms of capillary leak syndrome should be closely monitored and receive standard symptomatic treatment, which may include a need for intensive care.
Potential for Tumor Growth Stimulatory Effects on Malignant Cells
The G-CSF receptor, through which pegfilgrastim and filgrastim act, has been found on tumor cell lines. The possibility that pegfilgrastim acts as a growth factor for any tumor type, including myeloid malignancies and myelodysplasia, diseases for which pegfilgrastim is not approved, cannot be excluded.
The most common adverse reactions (≥ 5% difference in incidence) in placebo-controlled clinical trials are bone pain and pain in extremity.
