WIKI ANALYSIS
Abraxis BioScience, Inc. (Nasdaq: ABII) is an American biotechnology company that specializes in reformulating existing drugs to increase their efficacy or decrease side effects. For example, the company might change the way an existing drug is disolved in water, or add an accompanying chemical to change the properties of the drug. In both cases, the underlying drug is the same, but its efficacy or toxicity can change dramatically. A great example of this is the company's signature cancer drug Abraxane. Abraxane is simply a reformulation of the preexisting, generic cancer drug Taxol, sold by Bristol-Myers Squibb Company (BMY). Taxol is not naturally soluble in water, so pharmaceutical companies have traditional used camphor oil to dissolve the drug in the bloodstream. Camphor oil is toxic to patients however, which makes Taxol unpleasant to take and limits the dose that can be given. Moreover, the camphor oil gave rise to several side effects including nausea and in some cases allergic reactions to the drug. Abraxis found a new way to dissolve Taxol in water which does not require the use of camphor oil, and was able to patent the new, reformulated Taxol and call it Abraxane. The company's Nab delivery system dissolves the drug using albumin, a naturally occurring human protein. As demonstrated by Abraxane clinical trials, this method of drug delivery is safer for the patient, allows for the delivery of larger payload of the drugs and is more potent; Abraxis has a response rate almost double that of solvent-based therapies.[1] Abraxis is playing a significant role in using technologies like nanoparticle and polymeric drugs to target diseases like cancer and chronic infections.
Abraxane is the company's only FDA approved drug and it is used primarily to treat metastatic breast cancer (cancer that has spread from the primary site to other locations in the body). Although Abraxis' fortunes are dependent on Abraxane's success in the near term the drug is only part of Abraxis' story. The company's future prospects are tied more broadly to its ability to adapt its nab drug delivery platform to other drugs - the company hopes to find other drugs which it can improve by reformulating them.
Using its new technology the company plans to develop safer and more potent drugs for a number of different types of cancer, including ovarian, prostate, gastrointestinal, pancreatic, head and neck, cervical, and lung cancers.[2] Abraxis has three other drugs entering FDA clinical trials that use the nab technology platform to treat tumors. [3] Additionally, there are approximately 30 company-sponsored and 90 third-party clinical studies designed to investigate additional uses for Abraxane.[4] Besides discovering and developing new drugs for use with the nab technology, Abraxis plans to redevelop other firms’ existing treatments for use with the nab platform.

Business Financials
Abraxis is a fully integrated Biotechnology firm that discovers potential therapeutics used in the treatment of cancer and other serious illnesses and then develops and delivers them for patient use. The company’s revenue is driven primarily by the sale of Abraxane, which uses the company’s innovative nab technology. Abraxane is used in the treatment of metastatic breast cancer and has been approved for commercial use in the United States, Canada, India, and the European Union and is awaiting approval in Australia, Russia, Korea, and China.[6]
Business & Financial Metrics[7]
In 2009, Abraxis incurred a net loss of $104.8 million on revenues of $359.1 million. This represents a 62.1% reduction in net loss on a 3.5% decrease in total revenues from 2008, when the company lost $276.8 million on revenues of $306.2 million.
Business Segments[7]
Abraxis's primary source of revenue is its flagship drug, Abraxane. Abraxane sales accounted for 87.6% of the company's total revenues in 2009.
Key Trends and Forces
Abraxane Growth as a First-Line Treatment of Metastatic Breast Cancer
When an individual is diagnosed with cancer, a physician prescribes a specific beginning treatment. This initial drug or therapy is known as a first-line treatment. Only after the first-line treatment proves to be ineffective, are second- or third-line treatments given. Consequently, the first-line market for cancer drugs is generally the largest and most profitable. After going through Clinical Trials, the FDA decides the lines of treatment in which a drug is approved for use. In 2006, Canada became the first country to approve Abraxane for use as a first-line treatment of metastatic breast cancer.[8] As of March 2008, however, Abraxane has yet to be approved as a first-line treatment in any other country. In the United States, for example, Abraxane is approved for use after failure of first-line chemotherapy or a relapse within 6 months after first-line treatment.[9] Abraxis is actively trying to prove the effectiveness of Abraxane as a first-line drug in order to receive additional regulatory approvals for use as a first-line treatment. In June 2007, Abraxis presented results from Phase II comparison trials that showed that the administration of Abraxis as a first-line treatment of metastatic breast cancer resulted in longer patient survival and a better toxicity profile than Sanofi Aventis’ Taxotere.[10]
Ongoing Health Care and Medicare Reform
While the Federal Drug Administration is prohibited from taking into consideration a drug’s price during the approval process, the success of a cancer drug often relies on whether third party insurers like Medicare and Medicaid agree to reimburse patients for its use.[11] In response to cut costs, Medicare and Medicaid have demonstrated a renewed emphasis on the marginal benefit of drugs when compared to their prices. In 2006, one dose of Abraxane cost $4,200; approximately 25 times more than Bristol-Myers Squibb’s Taxol, a drug that also treats metastatic breast cancer.[12] In order for Abraxane to continue to receive Medicare and Medicaid reimbursement, it will have to prove that its results merit the significant additional costs. A 2006 Phase III trial that compared Abraxane and Taxol as treatments of metastatic breast cancer yielded unclear results. While targeted tumors were almost twice as likely to respond to Abraxane as Taxol, there was no statistically significant difference in the overall survival rate of patients treated with the two drugs.[13]
Competition
Abraxane is essentially an improved version of a widely available drug known as Taxol (or, by its generic name, paclitaxel). As taxol is not soluble in water, which means it can't enter the bloodstream on its own, different companies have employed different strategies to make the drug soluble. It's the way in which Taxol is made soluble that distinguishes Abraxane from its competitors and makes the drug less toxic.
Abraxis’ main competitors are other companies selling taxanes and paclitaxel.
Bristol-Myers Squibb: produces Taxol, a drug used for the treatment of several tumor-based cancers.[14] There are also generic forms of Taxol under the name of paclitaxel, which have significantly reduced Taxol the past three years.[15]
Sanofi Aventis: sells Taxotere, the only chemotherapy treatment approved for use in five different types of cancer. Since it is used for treatment in a greater number of cancers, sales of Taxotere are much higher than both Abraxane and Taxol.[16]
