Cancer Drug Discovery Targeting the Tumor Suppressor p53

In July 2007, we entered into a license agreement with the Buck Institute for Age Research under which we exclusively licensed the worldwide intellectual property rights for technologies designed to generate novel therapeutics and identify new drug discovery targets. There are no up-front or milestone payments required by us under the license agreement. If products are successfully developed incorporating any of the licensed technologies, we will pay the Buck Institute royalties based on a percentage of net sales. The term of the agreement will continue until the last patent claiming a licensed product under the agreement expires. However, the license agreement may be terminated earlier by either party upon the other party’s failure to timely cure a material breach under the agreement or upon the other party’s bankruptcy or insolvency.

Through this license agreement, we own the rights to a proprietary discovery platform designed to discover new chemical entities that remediate the signaling activities of the tumor suppressor p53 in p53-dysfunctional cancer cells. Loss of p53 activity is associated with one-half of all human tumors, often rendering these cancer cells resistant to conventional therapies. The licensed technologies have made the discovery of reactivators of appropriate p53 signaling behavior possible. Inherent in the design of the technologies is a strategy to develop therapeutics that selectively stimulate programmed cell death in p53-dysfunctional cancer cells and that would leave healthy cells expressing normal p53 unaffected.

The therapies developed in this program will target a specific population of aberrant (tumor) cells and forge a novel class of chemotherapeutics that have the potential to be much more potent than general inhibitors of cell proliferation or inducers of cell death. In the era of personalized medicine, and in combination with our emerging diagnostic methodologies, we believe this program will generate a novel pipeline of drugs that promise cancer patients greater proficiency with fewer side effects.
