Company Developing Infrastructure and Alliances in Asia-Pacific Region
LOS ANGELES--(HSMN NewsFeed)--Abraxis BioScience, Inc. (NASDAQ:ABII ), a fully integrated biotechnology company, today announced it has received approval from the China State Food and Drug Administration to market ABRAXANE® paclitaxel for Injection (Albumin Bound) for the treatment of breast cancer after failure of standard chemotherapy for metastatic disease or relapse within 6 months of adjuvant chemotherapy. The Phase III clinical trials in the U.S. and China on which this approval was based demonstrated that ABRAXANE doubled the response rate, significantly prolonged time to tumor progression, and in the U.S. trial, significantly improved overall survival versus Taxol® in the approved indication.
Data from the U.S. pivotal head-to-head trial demonstrated that ABRAXANE nearly doubled the overall response rate versus Taxol (33% vs. 19%; P = .001) and achieved a 25% percent improvement in time to tumor progression when compared to Taxol. Furthermore, patients receiving ABRAXANE in the second-line setting had a significantly prolonged survival by an additional 27% compared to solvent-based Taxol. The tolerability with ABRAXANE and Taxol was comparable, despite the 50% greater dose of paclitaxel administered as ABRAXANE.
A second head-to-head trial in Chinese patients with metastatic breast cancer further demonstrated the improved efficacy of ABRAXANE compared to solvent-based paclitaxel Injection. ABRAXANE significantly improved overall response rate versus solvent-based paclitaxel Injection (54% vs. 29%; P = <.001) and achieved a 26% percent improvement in progression free survival when compared to solvent-based paclitaxel Injection (7.6 months vs. 6.2 months; P = 0.118). Both therapies had similar toxicity profiles.
ABRAXANE is now approved for marketing in 35 countries. Abraxis has three issued Chinese patents covering ABRAXANE, as well as five additional pending patent applications in China.
In the Asia-Pacific region, ABRAXANE was approved in India in November 2007 and in Korea in April 2008. ABRAXANE is under regulatory review by the Therapeutic Goods Administration (TGA) in Australia and by the Federal Authority for Healthcare and Social Development Regulation in Russia for the treatment of breast cancer. In March 2008, the Japanese licensee of Abraxis, Taiho Pharmaceutical Co., filed a New Drug Application (J-NDA) with the Ministry of Health, Labour and Welfare to market ABRAXANE for the treatment of breast cancer in Japan.
“The approval for ABRAXANE in China provides the most populated country in the world with an important new treatment option for women with metastatic breast cancer,” said Patrick Soon-Shiong, M.D., Chairman and Chief Executive Officer of Abraxis BioScience. “With cancer rates on the rise in China, the introduction of a new taxane therapy such as ABRAXANE is particularly important.”
From 2000 to 2005, the incidence of breast cancer in China has increased 25% to 25 out of every 100,000 women. There are approximately 400,000 women with breast cancer in China, with approximately 168,000 new cases of breast cancer reported in China each year. In the commercial center of Shanghai, in 2007, 55 out of every 100,000 women had breast cancer, a 31 percent increase since 1997, and about 45 out of every 100,000 women in Beijing had the disease, representing a 23 percent increase during the past 10 years. According to IMS market data, there were approximately 1.5 million vials of paclitaxel injection (30 mg/vial) sold in China in 2007, representing total market value of $83 million. This represents a 30% increase over 2006, when the total market value of paclitaxel injection was approximately $64 million. The total taxane market in China was approximately $167 million in 2007.
ABRAXANE® is a solvent-free chemotherapy treatment option for metastatic breast cancer. Developed using Abraxis BioScience's proprietary nabTM technology platform, ABRAXANE is a protein-bound chemotherapy agent, which combines paclitaxel with albumin, a naturally-occurring human protein, to deliver the drug and eliminates the need for solvents in the administration process. Because solvents are not used for administration, ABRAXANE allows for the delivery of a 49% higher dose compared to solvent-based paclitaxel (Taxol®) without compromising safety and tolerability. In a previous randomized Phase III study of metastatic breast cancer patients, ABRAXANE demonstrated nearly double the overall tumor response rate compared to solvent-based paclitaxel.
ABRAXANE is currently in various stages of investigation for the treatment of the following cancers: first-line metastatic breast, non-small cell lung, malignant melanoma, pancreatic, and gastric. The most serious adverse events associated with ABRAXANE in the randomized metastatic breast cancer study for which FDA approval was based included neutropenia, anemia, infections, sensory neuropathy, nausea, vomiting and myalgia/arthralgia. Other common adverse reactions included anemia, asthenia, diarrhea, ocular/visual disturbances, fluid retention, alopecia, hepatic dysfunction, mucositis and renal dysfunction.

ABRAXANE was developed by Abraxis BioScience and is marketed in the United States under a co-promotion agreement between Abraxis and AstraZeneca.
