Increased survival in pancreatic cancer with nab-paclitaxel plus gemcitabine. N Engl J Med 2013. DOI: 10.1056/NEJMoa1304369.
“The peer-reviewed publication of the MPACT results in the New England Journal of Medicine further validates the importance of this treatment regimen,” said Markus Renschler, M.D., Corporate Vice President, Global Head of Hematology and Oncology Medical Affairs at Celgene Corporation. “These results led to the U.S. Food and Drug Administration’s approval of ABRAXANE for the first-line treatment of patients with metastatic adenocarcinoma of the pancreas, in combination with gemcitabine.”
About the MPACT Study
In the MPACT (Metastatic Pancreatic Adenocarcinoma Clinical Trial) study, a Celgene-sponsored, open-label, randomized, international study, a total of 861 patients were randomized 1:1 (431 patients to the ABRAXANE/gemcitabine group and 430 patients to the gemcitabine group). Patients randomized to ABRAXANE/gemcitabine received ABRAXANE as an intravenous infusion over 30-40 minutes at a dose of 125 mg/m2 followed by gemcitabine as an intravenous infusion over 30-40 minutes at a dose of 1000 mg/m2 given on Days 1, 8 and 15 of each 28-day cycle. In the comparator treatment group, gemcitabine monotherapy was administered at a dose of 1000 mg/m2 given weekly for 7 weeks followed by a 1-week rest period in Cycle 1 and in Cycle 2 and onwards was administered on Days 1, 8 and 15 of a 28 day cycle. The primary endpoint for the study was overall survival. Secondary endpoints were progression-free survival and overall response rate determined by independent radiological review. Other endpoints included progression-free survival and overall response rate as determined by the investigator, and the safety and tolerability of the combination in this patient population.
About Pancreatic Cancer
Pancreatic cancer is the fourth-leading cause of cancer-related deaths in the United States and Europe. There are two main types of pancreatic cancer tumors: exocrine and neuroendocrine. Adenocarcinoma is a sub-type of exocrine tumors and accounts for about 95% of cancers of the pancreas. More than half of patients with pancreatic cancer are diagnosed after their cancer has already spread. The average life expectancy after diagnosis with metastatic disease is only three months.
About ABRAXANE®
ABRAXANE is an albumin-bound form of paclitaxel that is manufactured using patented nab® technology. ABRAXANE is formulated with albumin, a human protein, and is free of solvents.
In the United States, ABRAXANE was first approved in January 2005 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. ABRAXANE has been globally approved in more than forty countries for the treatment of metastatic breast cancer (MBC).
In October 2012, ABRAXANE was approved by the FDA for the first-line treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC), in combination with carboplatin, in patients who are not candidates for curative surgery or radiation therapy. ABRAXANE is also approved for the treatment of NSCLC in Argentina, Australia, Japan, and New Zealand.
In September 2013, the FDA approved ABRAXANE as first–line treatment of patients with metastatic adenocarcinoma of the pancreas, in combination with gemcitabine.
Important Safety Information about ABRAXANE
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 clinical studies, Grade 3-4 neutropenia occurred in 34% of patients with metastatic breast cancer (MBC), 47% of patients with non–small cell lung cancer (NSCLC), and 38% of patients with pancreatic cancer
Monitor for myelotoxicity by performing complete blood cell counts frequently, including prior to dosing on Day 1 (for MBC) and Days 1, 8, and 15 (for NSCLC and for pancreatic cancer)
Do not administer ABRAXANE to patients with baseline absolute neutrophil counts (ANC) of less than 1500 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 either MBC or NSCLC
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 a level >100,000 cells/mm3
In patients with NSCLC, resume treatment if recommended at permanently reduced doses for both weekly ABRAXANE and every-3-week carboplatin after ANC recovers to at least 1500 cells/mm3 and platelet count of at least 100,000 cells/mm3 on Day 1 or to an ANC of at least 500 cells/mm3 and platelet count of at least 50,000 cells/mm3 on Days 8 or 15 of the cycle
In patients with adenocarcinoma of the pancreas, withhold ABRAXANE and gemcitabine if the ANC is less than 500 cells/mm3 or platelets are less than 50,000 cells/mm3 and delay initiation of the next cycle if the ANC is less than 1500 cells/mm3 or platelet count is less than 100,000 cells/mm3 on Day 1 of the cycle. Resume treatment with appropriate dose reduction if recommended
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 ABRAXANE treatment until resolution to Grade 1 or 2 for MBC or until resolution to ≤ Grade 1 for NSCLC and pancreatic cancer followed by a dose reduction for all subsequent courses of ABRAXANE
Sepsis
Sepsis occurred in 5% of patients with or without neutropenia who received ABRAXANE in combination with gemcitabine
Biliary obstruction or presence of biliary stent were risk factors for severe or fatal sepsis
If a patient becomes febrile (regardless of ANC), initiate treatment with broad-spectrum antibiotics
For febrile neutropenia, interrupt ABRAXANE and gemcitabine until fever resolves and ANC ≥1500 cells/mm3, then resume treatment at reduced dose levels
Pneumonitis
Pneumonitis, including some cases that were fatal, occurred in 4% of patients receiving ABRAXANE in combination with gemcitabine
Monitor patients for signs and symptoms and interrupt ABRAXANE and gemcitabine during evaluation of suspected pneumonitis
Permanently discontinue treatment with ABRAXANE and gemcitabine upon making a diagnosis of pneumonitis
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
For MBC and NSCLC, the starting dose should be reduced for patients with moderate or severe hepatic impairment
For pancreatic adenocarcinoma, ABRAXANE is not recommended 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

There have been reports of congestive heart failure and left ventricular dysfunction 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
No toxicities occurred notably more frequently among patients ≥65 years of age who received ABRAXANE for MBC
Myelosuppression, peripheral neuropathy, and arthralgia were more frequent in patients ≥65 years of age treated with ABRAXANE and carboplatin in NSCLC
Diarrhea, decreased appetite, dehydration, and epistaxis were more frequent in patients 65 years or older compared with patients younger than 65 years old who received ABRAXANE and gemcitabine in adenocarcinoma of the pancreas
Renal Impairment
The use of ABRAXANE has not been studied in patients with renal impairment
DOSAGE AND ADMINISTRATION
For MBC and NSCLC, dose adjustment is recommended for patients with moderate and severe hepatic impairment. Withhold ABRAXANE if AST >10 x ULN or if bilirubin >5 x ULN
For adenocarcinoma of the pancreas, withhold ABRAXANE if bilirubin ≥1.26 x ULN or if AST >10 x ULN
Dose reductions or discontinuation may be needed based on severe hematologic, neurologic, cutaneous, or gastrointestinal toxicity

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 human albumin has not been studied
There have been reports of congestive heart failure and left ventricular dysfunction 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
No toxicities occurred notably more frequently among patients ≥65 years of age who received ABRAXANE for MBC
Myelosuppression, peripheral neuropathy, and arthralgia were more frequent in patients ≥65 years of age treated with ABRAXANE and carboplatin in NSCLC
Diarrhea, decreased appetite, dehydration, and epistaxis were more frequent in patients 65 years or older compared with patients younger than 65 years old who received ABRAXANE and gemcitabine in adenocarcinoma of the pancreas
Renal Impairment
The use of ABRAXANE has not been studied in patients with renal impairment
DOSAGE AND ADMINISTRATION
For MBC and NSCLC, dose adjustment is recommended for patients with moderate and severe hepatic impairment. Withhold ABRAXANE if AST >10 x ULN or if bilirubin >5 x ULN
For adenocarcinoma of the pancreas, withhold ABRAXANE if bilirubin ≥1.26 x ULN or if AST >10 x ULN
Dose reductions or discontinuation may be needed based on severe hematologic, neurologic, cutaneous, or gastrointestinal toxicity
Monitor patients closely
