ABRAXANE for Injectable Suspension (paclitaxel protein-bound particles for injectable suspension)(albumin-bound) is indicated for the treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within 6 months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated.
Important Safety Information
WARNING – NEUTROPENIA
Do not administer ABRAXANE therapy to patients who have baseline neutrophil counts of less than 1500 cells/mm3. In order to monitor the occurrence of bone marrow suppression, primarily neutropenia, which may be severe and result in infection, it is recommended that frequent peripheral blood cell counts be performed on all patients receiving ABRAXANE
Note: An albumin form of paclitaxel may substantially affect a drug’s functional properties relative to those of drug in solution. DO NOT SUBSTITUTE FOR OR WITH OTHER PACLITAXEL FORMULATIONS
CONTRAINDICATIONS
Neutrophil Counts
ABRAXANE should not be used in patients who have baseline neutrophil counts of < 1500 cells/mm3
Hypersensitivity
Patients who experience a severe hypersensitivity reaction to ABRAXANE should not be rechallenged with the drug
WARNINGS AND PRECAUTIONS
Hematologic Effects
Bone marrow suppression (primarily neutropenia) is dose-dependent and a dose-limiting toxicity of ABRAXANE. In a clinical study, Grade 3-4 neutropenia occurred in 34% of patients with metastatic breast cancer (MBC)
Monitor for myelotoxicity by performing complete blood cell counts frequently, including prior to dosing on Day 1
Do not administer ABRAXANE to patients with baseline absolute neutrophil counts (ANC) of less than 1,500 cells/mm3
In the case of severe neutropenia ( < 500 cells/mm3 for 7 days or more) during a course of ABRAXANE therapy, reduce the dose of ABRAXANE in subsequent courses in patients with MBC
Resume treatment with every-3-week cycles of ABRAXANE after ANC recovers to a level > 1500 cells/mm3 and platelets recover to > 100,000 cells/mm3
Nervous System
Sensory neuropathy is dose- and schedule-dependent
The occurrence of Grade 1 or 2 sensory neuropathy does not generally require dose modification
If ≥ Grade 3 sensory neuropathy develops, withhold until resolution to Grade 1 or 2 followed by a dose reduction for all subsequent courses of ABRAXANE
Hypersensitivity
Severe and sometimes fatal hypersensitivity reactions, including anaphylactic reactions, have been reported
Patients who experience a severe hypersensitivity reaction to ABRAXANE should not be rechallenged with this drug
Hepatic Impairment
Because the exposure and toxicity of paclitaxel can be increased with hepatic impairment, administration of ABRAXANE in patients with hepatic impairment should be performed with caution
Patients with hepatic impairment may be at an increased risk of toxicity, particularly from myelosuppression, and should be monitored for development of profound myelosuppression
For MBC, the starting dose should be reduced for patients with moderate or severe hepatic impairment
Albumin (Human)
ABRAXANE contains albumin (human), a derivative of human blood
Use in Pregnancy: Pregnancy Category D
ABRAXANE can cause fetal harm when administered to a pregnant woman
If this drug is used during pregnancy, or if the patient becomes pregnant while receiving this drug, the patient should be apprised of the potential hazard to the fetus
Women of childbearing potential should be advised to avoid becoming pregnant while receiving ABRAXANE
Use in Men
Men should be advised not to father a child while receiving ABRAXANE
ADVERSE REACTIONS
Randomized Metastatic Breast Cancer (MBC) Study
The most common adverse reactions (≥20%) with single-agent use of ABRAXANE vs paclitaxel injection in the MBC study are alopecia (90%, 94%), neutropenia (all cases 80%, 82%; severe 9%, 22%), sensory neuropathy (any symptoms 71%, 56%; severe 10%, 2%), abnormal ECG (all patients 60%, 52%; patients with normal baseline 35%, 30%), fatigue/asthenia (any 47%, 39%; severe 8%, 3%), myalgia/arthralgia (any 44%, 49%; severe 8%, 4%), AST elevation (any 39%, 32%), alkaline phosphatase elevation (any 36%, 31%), anemia (any 33%, 25%; severe 1%, < 1%), nausea (any 30%, 22%; severe 3%, < 1%), diarrhea (any 27%, 15%; severe < 1%, 1%) and infections (24%, 20%), respectively
Sensory neuropathy was the cause of ABRAXANE discontinuation in 7/229 (3%) patients
Other adverse reactions of note with the use of ABRAXANE vs paclitaxel injection included vomiting (any 18%, 10%; severe 4%, 1%), fluid retention (any 10%, 8%; severe 0%, < 1%), mucositis (any 7%, 6%; severe < 1%, 0%), hepatic dysfunction (elevations in bilirubin 7%, 7%), hypersensitivity reactions (any 4%, 12%; severe 0%, 2%), thrombocytopenia (any 2%, 3%; severe < 1%, < 1%), neutropenic sepsis ( < 1%, < 1%), and injection site reactions ( < 1%, 1%), respectively. Dehydration and pyrexia were also reported
Renal dysfunction (any 11%, severe 1%) was reported in patients treated with ABRAXANE (n=229)
In all ABRAXANE-treated patients (n=366), ocular/visual disturbances were reported (any 13%; severe 1%)
Severe cardiovascular events possibly related to single-agent ABRAXANE occurred in approximately 3% of patients and included cardiac ischemia/infarction, chest pain, cardiac arrest, supraventricular tachycardia, edema, thrombosis, pulmonary thromboembolism, pulmonary emboli, and hypertension
Cases of cerebrovascular attacks (strokes) and transient ischemic attacks have been reported
Postmarketing Experience With ABRAXANE and Other Paclitaxel Formulations
Severe and sometimes fatal hypersensitivity reactions have been reported with ABRAXANE. The use of ABRAXANE in patients previously exhibiting hypersensitivity to paclitaxel injection or to human albumin has not been studied
There have been reports of congestive heart failure, left ventricular dysfunction, and atrioventricular block with ABRAXANE, primarily among individuals with underlying cardiac history or prior exposure to cardiotoxic drugs
There have been reports of extravasation of ABRAXANE. Given the possibility of extravasation, it is advisable to monitor closely the ABRAXANE infusion site for possible infiltration during drug administration
DRUG INTERACTIONS
Caution should be exercised when administering ABRAXANE concomitantly with medicines known to inhibit or induce either CYP2C8 or CYP3A4
USE IN SPECIFIC POPULATIONS
Nursing Mothers
It is not known whether paclitaxel is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother
Pediatric
The safety and effectiveness of ABRAXANE in pediatric patients have not been evaluated
Geriatric
A higher incidence of epistaxis, diarrhea, dehydration, fatigue, and peripheral edema was found in patients 65 years or older who received ABRAXANE for MBC in a pooled analysis of clinical studies
Renal Impairment
There are insufficient data to permit dosage recommendations in patients with severe renal impairment or end stage renal disease (estimated creatinine clearance < 30 mL/min)
DOSAGE AND ADMINISTRATION
Do not administer ABRAXANE to any patient with total bilirubin greater than 5 x ULN or AST greater than 10 x ULN
Reduce starting dose in MBC patients with moderate to severe hepatic impairment
Dose reductions or discontinuation may be needed based on severe hematologic or neurologic toxicity
Monitor patients closely
