Spectrum Pharmaceuticals Announces Presentation of EOquin(TM) Phase 2 Data at the 21st European Association of Urology Annual Congress in Paris, France

End of Phase 2 and pre-IND meeting held with the FDA

A Phase 3 study is expected to be initiated after a twenty patient pilot study is completed later this year

IRVINE, Calif., April 6 (HSMN NewsFeed) -- Spectrum Pharmaceuticals, Inc. (Nasdaq: SPPI ) today announced that results of a Phase 2 marker lesion study of EOquin(TM) by intravesical instillation in superficial bladder cancer are being presented today at the 21st European Association of Urology Annual Congress in Paris, France by Dr. Antoine G. van der Heijden from the Department of Urology, University Medical Centre Nijmegen, the Netherlands.

A total of 46 patients with multiple lesions of superficial bladder cancer were entered into this multicenter study. After surgical removal of all except one "marker" lesion, patients received six weekly instillations of EOquin(TM) into the bladder. Complete disappearance of the tumor was histologically documented in 30 patients. The data indicates that EOquin(TM) by intravesical instillation demonstrates significant anti-tumor activity in superficial bladder cancer and is well tolerated in patients.

EOquin(TM) is the tradename for apaziquone, a potential anti-cancer agent, formulated for administration directly into the urinary bladder. It is activated by certain enzymes present in higher amounts in cancer cells than in normal cells.

The American Cancer Society estimates there will be more than 61,420 new cases of and 13,060 deaths from bladder cancer in 2006 in the United States. There is an estimated 400,000 patient population currently in the U.S. and an even greater number estimated in Europe. Superficial bladder cancer accounts for 75 to 85 percent of all cases of bladder cancer at first diagnosis. The initial treatment is usually surgical removal of the tumor(s), often followed by additional immunotherapy or chemotherapy drugs instilled directly in the bladder to prevent or delay recurrences.

"We continue to believe that the treatment of refractory superficial bladder cancer represents a significant unmet medical need," stated Rajesh C. Shrotriya, M.D., Chairman, Chief Executive Officer and President of Spectrum Pharmaceuticals, Inc. "In fact, no new drugs have been marketed for treatment of superficial bladder cancer in more than 20 years. This latest study definitively confirms that EOquin(TM) has meaningful anti-tumor activity against this cancer and is well tolerated by the patients. After a successful 'end of Phase 2 and pre-IND' meeting with the FDA held earlier this year, we are now planning to initiate a small pilot study, which should be followed by a randomized Phase 3 trial before the end of this year."
