GPC Biotech Today Announced Results of Survival Analysis from the SPARC Trial

Overall Survival Results Do Not Achieve Statistical Significance

IRVINE, Calif., October 30, 2007 /PRNewswire-FirstCall/ -- Spectrum Pharmaceuticals, Inc.'s licensee, GPC Biotech, today announced that the Phase 3 SPARC trial evaluating satraplatin for the treatment of hormone-refractory prostate cancer did not meet its primary efficacy endpoint.

"We are indeed disappointed that the overall survival data for satraplatin did not achieve statistical significance. Drug development is inherently risky and clinical studies do sometimes fail for various reasons, which is why we built Spectrum on a business model based on a diversified portfolio of several late- and early-stage drug candidates. We are not dependent on the success or failure of any one drug," said Rajesh C. Shrotriya, M.D., Chairman, President and Chief Executive Officer of Spectrum Pharmaceuticals, Inc. "We will continue to aggressively develop our four late-stage drugs, ISO-Vorin(TM), which has a January 11th FDA action date; sumatriptan injection, which we will launch with PAR Pharmaceutical Companies in the second-half of 2008; EOquin(R), which is currently enrolling patients in two Phase 3 trials; and ozarelix, where we are currently working on the protocol for the pivotal registrational trial. Furthermore, we are currently planning and/or conducting studies for elsamitrucin, lucanthone, ortataxel, RenaZorb(TM), SPI-1620 and SPI-205."
