Independent Data Monitoring Board Recommends Expedited Interim Analysis of Overall Survival Data for Satraplatin Phase 3 Trial

IRVINE, Calif., May 17 (HSMN NewsFeed) -- Spectrum Pharmaceuticals, Inc. (Nasdaq: SPPI ) today announced that its satraplatin co-development partner, GPC Biotech AG, was notified by the independent Data Monitoring Board (DMB) for the satraplatin Phase 3 registrational trial, SPARC (Satraplatin and Prednisone Against Refractory Cancer) that it wishes to conduct an expedited interim analysis of overall survival data from the SPARC trial. The company has agreed to this request and the DMB is expected to meet to discuss the data prior to the end of the second quarter of 2006.

As previously announced, following the interim efficacy analysis conducted on April 25, 2006, the DMB recommended that the SPARC trial continue as planned. The focus of that analysis was progression-free survival (PFS) and safety data. PFS remains the endpoint of the SPARC trial for accelerated approval in the U.S. and is also the basis, along with supporting overall survival data, for approval in Europe.

Spectrum and GPC Biotech do not have access to any of the data that caused the DMB to request this expedited review of overall survival, however, in its April 25th meeting, the DMB also had access to preliminary overall survival data. The companies are now, and will continue to remain, blinded to the data during this review process.

The Data Monitoring Board consists of independent oncology and statistical experts whose primary responsibility is to monitor, on a periodic basis, the data from the SPARC trial and to provide recommendations to the companies on whether the study should proceed as originally planned, be modified or be discontinued for efficacy or safety reasons. Members of the DMB are independent from Spectrum and GPC Biotech and do not participate as clinical investigators in the SPARC trial.

About Satraplatin

Satraplatin, an investigational drug, is a member of the platinum family of compounds. Over the past two decades, platinum-based drugs have become a critical part of modern chemotherapy treatments and are used to treat a wide variety of cancers. Unlike the platinum drugs currently on the market, all of which require intravenous administration, satraplatin is an orally bioavailable compound and is given as capsules that patients can take at home.

Spectrum out-licensed satraplatin to GPC Biotech AG in 2002, and GPC Biotech fully funds all development expenses. In December 2005, the accrual to the SPARC trial was completed and the rolling submission of a New Drug Application (NDA) for satraplatin with the U.S. Food and Drug Administration (FDA) was initiated. Also in December 2005, GPC Biotech signed a co-development and license agreement with Pharmion GmbH, a wholly owned subsidiary of Pharmion Corporation, under which Pharmion was granted exclusive commercialization rights to satraplatin for Europe and certain other territories.

Satraplatin has been studied in clinical trials involving a range of tumors, and Phase 2 trials have been completed in HRPC, ovarian cancer and small cell lung cancer. Other trials evaluating the effects of satraplatin in combination with radiation therapy, in combination with other cancer therapies and in various other cancers are underway or planned.
