“Our revenues more than doubled in the second quarter of 2006 compared to the same period in 2005 due to our co-development and license agreement with Pharmion, and we are on track to reach our revenue goal of approximately doubling revenues for the full year 2006,” said Mirko Scherer, Ph.D., Senior Vice President and Chief Financial Officer. “Our solid financial position is enabling us to move forward rapidly as we plan for the commercialization of satraplatin, in addition to developing our pipeline by initiating new trials with our lead drug candidate and advancing other programs.”



“The first half of 2006 was a busy time for GPC Biotech as we put into place critical elements to achieve the next stage in our corporate development, including key senior executive hires for our clinical development, and commercialization management teams,” said Bernd R. Seizinger, M.D., Ph.D., Chief Executive Officer. “The second half of this year will be a pivotal time for us as we anticipate the final results on progression-free survival from our SPARC Phase 3 registrational trial for satraplatin within the next ten weeks. If positive, we expect to complete our NDA filing with the FDA by year end and continue advancing our marketing and sales plans for the successful launch of satraplatin.”
