Ad hoc: GPC Biotech AG: FDA Oncologic Drugs Advisory Committee Recommends that FDA Wait f

Martinsried/Munich (Germany) and Princeton, N.J., July 25, 2007 - GPC Biotech AG (Frankfurt Stock Exchange: GPC; TecDAX index; NASDAQ: GPCB) today announced that the Oncologic Drugs Advisory Committee (ODAC) for the U.S. Food and Drug Administration (FDA) recommended (12-0) that the FDA should wait for the final survival analysis of the SPARC trial before deciding whether the satraplatin application is approvable for the treatment of hormone-refractory prostate cancer patients whose prior chemotherapy has failed. The FDA is not bound by the recommendations of advisory committees but will consider their advice when reviewing an applicant's NDA. The Company said that, due to a recent slowing in the reported rate of deaths in the SPARC trial, final overall survival results could take longer than the previously communicated timeframe of the fall of this year. Conference call scheduled As previously announced, the Company has scheduled a conference call to which participants may listen via live webcast, accessible through the GPC Biotech Web site at www.gpc-biotech.com or via telephone. A replay will be available via the Web site following the live event. The call, which will be conducted in English, will be held tomorrow, July 25th at 7:00 CET/1:00 AM ET, prior to the opening of the German markets. The dial-in numbers for the call are as follows: Participants from Europe: +49 (0)89 9982 99910 or +44 (0)20 7806 1950 Participants from the U.S.: 1-718-354-1385 END OF AD HOC ANNOUNCEMENT This ad hoc release contains forward-looking statements, which express the current beliefs and expectations of the management of GPC Biotech AG, including statements about the status of the FDA review process.
