Abraxis BioScience and The Scripps Research Institute Enter Exclusive Licensing Agreement for the Worldwide Development and Commercialization of a Novel Epothilone Therapeutic for the Treatment of Cancer.

LOS ANGELES -- Abraxis BioScience, Inc. (NASDAQ:ABBI), an integrated, global biopharmaceutical company, and The Scripps Research Institute (TRSI), one of the world's largest independent, non-profit biomedical research organizations, today announced the organizations have entered an exclusive licensing agreement for the worldwide development and commercialization of a novel epothilone therapeutic for the treatment of cancer. Epothilones belong to a new class of microtubule-stabilizing agents, which bind to the tubulin pathway to inhibit the growth and proliferation of cancer cells. Under the terms of the agreement, Abraxis has rights to eleven potential drug candidates for pre-clinical evaluation and selection of a lead candidate for clinical development. Financial terms of the agreement were not disclosed.

Abraxis will evaluate the therapeutic potential of TSRI's novel epothilones using its proprietary nab[TM] technology platform, which harnesses the unique natural properties of the human protein albumin to transport and deliver therapeutic agents to the site of disease. The nab platform eliminates the need for toxic solvents such as Cremophor EL([R]), which are used with other epothilones in development to allow the administration of the anticancer agent into the bloodstream. Serious side effects have been associated with the use of solvents.

"We are excited to enter into this exclusive agreement with The Scripps Research Institute, which enables Abraxis to expand its rapidly growing oncology pipeline with the addition of a novel epothilone therapy," said Neil P. Desai, Ph.D., vice president of research and development at Abraxis BioScience. "Abraxis is committed to the development of progressive cancer therapeutics and we look forward to initiating studies to evaluate this new class of cancer agents with our nab(TM) platform."

"Our preliminary research suggests the epothilones targeted for development by Abraxis BioScience are some of the most potent agents in this new class of drugs," said K.C. Nicolaou, Ph.D., chair, department of chemistry at The Scripps Research Institute. "Abraxis has a strong track record in the development and commercialization of cancer therapeutics. We are excited about our collaboration, which will enable further study of these novel epothilone agents."

About the nab[TM] Technology Platform

Developed by Abraxis BioScience, the nab[TM] technology platform harnesses the unique natural properties of the human protein albumin to transport and deliver therapeutic agents to the site of disease. The binding of albumin to the anticancer agent creates nanometer-sized particles, which are approximately 100 nanometers or 1/100th the size of a single red blood cell. These nab particles are readily incorporated into the body's own transport processes and are able to exploit the tumors' attraction to albumin, enabling the delivery of higher concentrations of the active drug to the target site. This may lead to an increase in the drug's antitumor effect and the potential for an effective response. In addition, nab platform eliminates the need for chemical solvents in the administration process, thus potentially improving safety through the elimination of solvent-related side effects.

The first FDA approved product to use the nab platform, ABRAXANE([R]), was launched in 2005 for the treatment of patients with metastatic breast cancer. Studies are ongoing to evaluate several other therapeutic candidates that employ the nab platform including nab-docetaxel (ABI-008), nab-rapamycin mTOR inhibitor (ABI 009), and nab-17AAG HSP90 inhibitor (ABI-010), among others.
