ABRAXANE Meets Primary Endpoint in Phase 3 Trial for Advanced Non-Small Cell Lung CancerABRAXANE, Carboplatin Combination Demonstrated Superiority to Taxol, Carboplatin in 1st Line Non-Small Cell Lung Cancer
LOS ANGELES--(HSMN NewsFeed)--Abraxis BioScience, Inc. (NASDAQ:ABII ) today announced that its randomized registrational Phase 3 clinical trial comparing ABRAXANE® (protein-bound paclitaxel) with Taxol® (paclitaxel) injection, both in combination with carboplatin, met the study’s primary endpoint by demonstrating that ABRAXANE showed a significant improvement in overall response rate as compared to Taxol, in the first-line treatment of patients with advanced non-small cell lung cancer (NSCLC), as assessed by independent radiologist review.
The Phase 3 trial completed enrollment of 1,052 patients in July 2009 at 102 sites globally and was led by principal investigator Mark Socinski, M.D., at the University of North Carolina Lineberger Comprehensive Cancer Center. It is one of the largest NSCLC clinical studies to be conducted. “This is exciting news for lung cancer patients and has important implications not only in late stage cancer but also in earlier stages of the disease,” Socinski said. The data will be submitted for consideration as a late breaking presentation at the upcoming American Society of Clinical Oncology (ASCO) meeting.
This trial is the subject of a special protocol assessment (SPA) with the FDA, which means that the design, clinical endpoints and statistical analyses of the trial have been previously agreed upon by the FDA. Specifically, the FDA agreed that the demonstration of a statistically superior response rate of the ABRAXANE and carboplatin combination over the Taxol and carboplatin combination would be sufficient to submit a supplemental new drug application (sNDA)(as a 505(b)(2) submission) for approval of ABRAXANE in combination with carboplatin for first line NSCLC.
“NSCLC is the most common form of lung cancer and is very difficult to treat. We are extremely pleased with the data from this Phase 3 combination study that demonstrated superiority of ABRAXANE over Taxol as we seek to bring new treatment options to these patients,” said Patrick Soon-Shiong, M.D., Executive Chairman and founder of Abraxis BioScience. “We anticipate filing an sNDA to the FDA during 2011 for what will be the second indication for ABRAXANE in the U.S.”
NSCLC accounts for approximately 85% of all lung cancer cases. The American Cancer Society (ACS) estimates that approximately 219,440 people will be diagnosed with lung cancer in the United States in 2009, and that approximately 159,000 deaths occur each year due to this cancer.i
ABRAXANE is a solvent-free chemotherapy treatment option for metastatic breast cancer which was developed using Abraxis BioScience's proprietary nab® technology platform. This protein-bound chemotherapy agent combines paclitaxel with albumin, a naturally-occurring human protein. By wrapping the albumin around the active drug, ABRAXANE can be administered to patients at higher doses, delivering higher concentrations of paclitaxel to the tumor site than solvent-based paclitaxel. ABRAXANE is currently in various stages of investigation for the treatment of the following cancers: expanded applications for metastatic breast, non-small cell lung, malignant melanoma, pancreatic and gastric.
The U.S. Food and Drug Administration approved ABRAXANE for Injectable Suspension (paclitaxel protein-bound particles for injectable suspension) (albumin-bound) in January 2005 for the treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within six months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated. For the full prescribing information for ABRAXANE please visit www.abraxane.com.
IMPORTANT SAFETY INFORMATION
The use of ABRAXANE has not been studied in patients with hepatic or renal dysfunction. In the randomized controlled trial, patients were excluded for baseline serum bilirubin >1.5 mg/dL or baseline serum creatinine >2 mg/dL.
ABRAXANE can cause fetal harm when administered to a pregnant woman. Women of childbearing potential should be advised to avoid becoming pregnant while receiving treatment with ABRAXANE.
Men should be advised to not father a child while receiving treatment with ABRAXANE. It is recommended that nursing be discontinued when receiving ABRAXANE therapy. ABRAXANE contains albumin (human), a derivative of human blood.
Caution should be exercised when administering ABRAXANE concomitantly with known substrates or inhibitors of CYP2C8 and CYP3A4.
ABRAXANE therapy should not be administered to patients with metastatic breast cancer who have baseline neutrophil counts of less than 1,500 cells/mm3. It is recommended that frequent peripheral blood cell counts be performed on all patients receiving ABRAXANE. Patients should not be retreated with subsequent cycles of ABRAXANE until neutrophils recover to a level >1,500 cells/mm3 and platelets recover to a level >100,000 cells/mm3 In the case of severe neutropenia (<500 cells/mm3 for 7 days or more) during a course of ABRAXANE therapy, a dose reduction for subsequent courses is recommended. Sensory neuropathy occurs frequently with ABRAXANE.
If grade 3 sensory neuropathy develops, treatment should be withheld until resolution to grade 1 or 2 followed by a dose reduction for all subsequent courses of ABRAXANE. Severe cardiovascular events possibly related to single-agent ABRAXANE occurred in approximately 3% of patients in the randomized trial. These events included chest pain, cardiac arrest, supraventricular tachycardia, edema, thrombosis, pulmonary thromboembolism, pulmonary embolism, and hypertension.
In the randomized metastatic breast cancer study, the most important adverse events included alopecia (90%), neutropenia (all cases 80%; severe 9%), sensory neuropathy (any symptoms 71%; severe 10%), asthenia (any 47%; severe 8%), myalgia/arthralgia (any 44%; severe 8%), anemia (all 33%; severe 1%), infections (24%), nausea (any 30%; severe 3%), vomiting (any 18%; severe 4%), diarrhea (any 27%; severe <1%), and mucositis (any 7%; severe <1%).
Other adverse reactions have included ocular/visual disturbances (any 13%; severe 1%), fluid retention (any 10%; severe 0%), hepatic dysfunction (elevations in bilirubin 7%, alkaline phosphatase 36%, AST [SGOT] 39%), renal dysfunction (any 11%; severe 1%), thrombocytopenia (any 2%; severe <1%), hypersensitivity reactions (any 4%; severe 0%), cardiovascular reactions (severe 3%), and injection site reactions (<1%). During postmarketing surveillance, rare occurrences of severe hypersensitivity reactions have been reported with ABRAXANE.
