SuperGen, Inc. Announces First Meeting of Newly Formed Scientific Advisory Board

DUBLIN, Calif., May 30 /PRNewswire-FirstCall/ -- SuperGen Inc. today announced that it has convened the first meeting of its newly formed Scientific Advisory Board (SAB).

The SAB is composed of three external and two Company scientists with expertise in the field of oncology whose role will be to help guide and counsel the Company as it advances its clinical programs, such as the recently announced MP470 Phase I study, and as the Company bolsters its pipeline through its proprietary CLIMB(TM) drug discovery engine.

"As we continue to discover promising drug candidates and move them into the clinic, it is crucial that we subject our discovery processes and lead drugs to the scrutiny of an experienced SAB having vast knowledge of the intricacies of oncology research and development," said James S. Manuso, Ph.D., Chairman, President and CEO of SuperGen. "The five members of our newly formed SAB have extensive expertise in structural biology, computational chemistry, cancer research and therapeutics development. We are honored to have them on our team. Their advice will add considerable value to our discovery and development efforts in the years ahead."

SuperGen's Scientific Advisory Board will consist of: -- Allan R. Goldberg, Ph.D., Chairman of the Scientific Advisory Board, adds expertise in commercial development in his current role as managing partner of The Channel Group LLC (TCG), a global life science venture management and strategic advisory organization.
