Exelixis, Inc.May 8 2013

Exelixis, Inc. (NASDAQ:EXEL) announced today that cabozantinib will be the subject of nine separate data presentations at the upcoming 2013 Annual Meeting of the American Society of Clinical Oncology (ASCO). The meeting will be held May 31-June 4, 2013, in Chicago, Illinois. Clinical data for cabozantinib will be featured in one oral presentation, one poster discussion, and seven general poster presentations. This year's ASCO Annual Meeting will be the first in which investigators present overall survival data for CRPC patients treated with cabozantinib as part of the phase 2, non-randomized expansion cohort.

“The nine data presentations at this year's ASCO Annual Meeting are indicative of the continued maturation and scope of the broad clinical development program for cabozantinib”

"The nine data presentations at this year's ASCO Annual Meeting are indicative of the continued maturation and scope of the broad clinical development program for cabozantinib," said Michael M. Morrissey, Ph.D., president and chief executive officer of Exelixis. "The program encompasses Exelixis-led trials, an ongoing collaboration with the National Cancer Institute's Cancer Therapy Evaluation Program (NCI-CTEP), and an Investigator-Sponsored Trial initiative - all of which will be represented in this year's ASCO data set. We look forward to these data presentations for cabozantinib in Chicago in just a few weeks."
