Cenomed and TorreyPines Therapeutics Enter into Licensing Agreement

IRVINE, Calif. & LA JOLLA, Calif.--(BUSINESS WIRE)--October 8, 2008--Cenomed BioSciences, LLC, a majority-owned subsidiary of Abraxis BioScience, Inc. (Nasdaq: ABII - News), and TorreyPines Therapeutics, Inc. (Nasdaq: TPTX - News) today announced that they have entered into an exclusive licensing agreement whereby Cenomed acquired from TorreyPines Therapeutics the worldwide development rights held by TorreyPines to three compounds: phenserine, PosiphenTM and bisnorcymcerine, for chemical defense and counterterrorism defense. Cenomed intends to develop these compounds for potential use in preventing toxicity following exposure to chemical organophosphorus nerve agents, including the chemical warfare agents sarin, soman, tabun and VX. Pursuant to the terms of the agreement, TorreyPines will receive potential future milestone and royalty payments.

These compounds may have the potential to protect against the toxic effects of nerve agent exposure and to potentially restore inactivated muscle cells and neural cells throughout the body. Cenomed intends to develop the compounds for use by the military, as well as civilians in the case of a chemical attack. Phenserine and Posiphen have been shown to be safe and well tolerated following oral administration in human clinical trials. Bisnorcymcerine has completed pre-clinical evaluation. Cenomed expects to initiate testing of the compounds against chemical warfare agent toxicity and prepare for the filing of an Investigational New Drug Application with the U.S. Food and Drug Administration (FDA).

In addition to protecting the soldier, the federal government has taken steps to protect civilians against terrorist attacks involving chemical warfare agents. Project BioShield provides measures to expedite research on medical treatments for exposure to these agents. The FDA amended regulations include the "animal efficacy rule," which provides that certain treatments for exposure to chemical warfare agents can be approved based on effectiveness data from animal studies when human studies cannot be ethically conducted because the studies would involve administering potentially lethal or disabling toxic agents to healthy human volunteers.

"Cenomed has a strong focus on chemical defense. This licensing agreement expands Cenomed's scope of research and potentially gives us a broader pipeline for developing therapies for unmet needs in chemical defense for both military and civilian applications," said David R. Helton, President and CEO of Cenomed BioSciences.

"We are pleased to reach agreement with Cenomed, a company uniquely positioned to develop these compounds for use in protecting our military and civilian population in the event of a chemical attack," said Evelyn Graham, acting Chief Executive Officer of TorreyPines.
