ABRAXANE® Demonstrates Statistically Significant Improvement in Overall Survival for Patients with Advanced Pancreatic Cancer in Phase III Study
BOUDRY, Switzerland --(Business Wire)--
Celgene International Sàrl, a subsidiary of Celgene Corporation (NASDAQ:
CELG) today announced that its phase III study of ABRAXANE®
(paclitaxel protein-bound particles for injectable suspension)
(albumin-bound) in combination with gemcitabine in treatment-naïve
patients with advanced pancreatic cancer met its primary endpoint of
overall survival. In the study, ABRAXANE in combination with gemcitabine
demonstrated a statistically significant improvement in overall survival
compared to patients receiving gemcitabine alone.
In the MPACT (Metastatic Pancreatic Adenocarcinoma Clinical Trial)
study, a Celgene-sponsored, open-label, randomized, international study
861 metastatic pancreatic cancer patients were randomized to receive
either ABRAXANE plus gemcitabine (125 mg/m2 followed by 1000
mg/m2 gemcitabine for 3 weeks followed by a week of rest) or
gemcitabine alone (1000 mg/m2 administered weekly for 7 weeks
followed by a week of rest followed by cycles of weekly administration
for 3 weeks followed by one week of rest).
The primary endpoint for the study is improvement in overall survival.
Secondary endpoints include evaluation of progression-free survival,
objective tumor response and the safety and tolerability of this
combination in this patient population.
The safety profile of ABRAXANE in combination with gemcitabine observed
in the study is comparable with other ABRAXANE clinical trials in
pancreatic cancer. A late-breaker placeholder abstract for this study
has been submitted to the American Society of Clinical Oncology's (ASCO)
2013 Gastrointestinal Cancers Symposium being held in San Francisco on
January 24-26, 2013.
Based on the results of the MPACT study, the company plans to submit
dossiers for registration in the US, Europe and other markets.
These results are from an investigational phase III study. ABRAXANE is
not currently approved for the treatment of advanced pancreatic cancer.
About Advanced Pancreatic Cancer
Advanced pancreatic cancer is a difficult-to-treat cancer with the
lowest survival rates among all cancer types. Across all patients with
pancreatic cancer, relative 5-year survival is 5.5%. There are two main
types of pancreatic cancer - adenocarcinomas, which accounts for
approximately 95% of all pancreatic cancer, and neuroendocrine tumors.
Pancreatic cancer is relatively uncommon with new cases accounting for
only 2.1% of all newly diagnosed cancers. However, pancreatic cancer is
the fourth most common cause of cancer death in the United States and
throughout the world.
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 is also available in Europe,
Canada, Russia, Australia, New Zealand, India, Japan, South Korea,
Bhutan, Nepal, United Arab Emirates and China for the treatment of
metastatic breast cancer.
In October 2012, ABRAXANE was approved by the U.S. Food and Drug
Administration for the first-line treatment of locally advanced or
metastatic non-small cell lung cancer, in combination with carboplatin,
in patients who are not candidates for curative surgery or radiation
therapy.
For the full prescribing information for ABRAXANE please visit http://www.abraxane.com.
ABRAXANE is currently in various stages of investigation for the
treatment of the following cancers: pancreatic, metastatic melanoma,
bladder, ovarian, and expanded applications for breast cancer.
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.
ABRAXANE is indicated for the first-line treatment of locally
advanced or metastatic non-small cell lung cancer, in combination with
carboplatin, in patients who are not candidates for curative surgery or
radiation therapy.
Important Safety Information
WARNING - NEUTROPENIA
-
Do not administer ABRAXANE therapy to patients who have baseline
neutrophil counts of less than 1,500 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 sould not be used in patients who have baseline neutrophil
counts of < 1,500 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
-
Monitor for myelotoxicity by performing complete blood cell counts
frequently, including prior to dosing on Day 1 for metastatic breast
cancer (MBC) and Days 1, 8, and 15 for non-small cell lung cancer
(NSCLC)
-
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
seven 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 >1,500 cells/mm3
and platelets recover to >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 1,500 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
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, treatment should be withheld
until resolution to Grade 1 or 2 for MBC or until resolution to =
Grade1 for NSCLC 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 re-challenged 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
-
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
