The EOquin SPA calls for two double blind, placebo-controlled, randomized Phase 3 clinical studies, each with 562 patients with Ta G1 G2 non-invasive bladder cancer. Patients will be randomized in a one-to-one ratio to EOquin or placebo. The primary endpoint will be the difference in the rate of tumor recurrence between the two treatment groups by year two. More than 55 centers are currently participating in Phase 3 testing of EOquin. Additional centers will be added as the EOquin trials progress.
"We are encouraged by the SPA we negotiated with the FDA, and we intend to work closely with the agency throughout the duration of the Phase 3 studies for EOquin. We believe that by gaining clarity about the primary and secondary endpoints for the Phase 3 studies with EOquin, we will be able to use the data we generate as the basis of a New Drug Application," said Rajesh C. Shrotriya, Spectrum's Chairman, President and Chief Executive Officer. "In addition, the advancement of EOquin into Phase 3 testing further validates our team's ability to select and develop promising drug candidates."
Additional information regarding the design, enrollment criteria, and participating centers for the Phase 3 trials with EOquin in non-invasive bladder cancer, is available at www.clinicaltrials.gov (keyword: EOquin).
About EOquin
EOquin (apaziquone for intravesical instillation) is a drug currently being developed for the treatment of non-invasive bladder cancer, which is a cancer that has invaded the inner most lining of the bladder. EOquin, an anti-cancer agent that becomes activated by reductase enzymes found in cancer cells, is formulated for administration directly into the urinary bladder. In a Phase 2 pilot study for which patient accrual was completed this year, EOquin instilled into the bladder following TUR-BT was well tolerated and was not absorbed in any detectable amount from the bladder wall into the bloodstream and therefore, would carry a low risk of systemic toxicity.
Spectrum Pharmaceuticals completed a multi-center, Phase 2 clinical trial in Europe. The results of the trial showed that EOquin was well-tolerated and produced a 67% CR (complete response) in patients, many of whom had been treated multiple times. The data from this study were presented to the FDA in early 2006.
About Bladder Cancer
The American Cancer Society estimates that 67,160 new cases of bladder cancer will be found in the United States, and approximately 180,000 in Europe, during 2007. In 2007 about 13,750 people will die of this disease in the U.S. At any given time, it is estimated that there are more than 400,000 patients in the U.S. and more than one million patients in Europe. Non-invasive bladder cancer accounts for 75 to 80 percent of all cases of bladder cancer at first diagnosis. According to Botteman et al., (PharmacoEconomics 2003), bladder cancer is the fifth most expensive cancer to treat. The initial treatment of this cancer is surgical removal of the tumor. Because of the high frequency of early recurrences of the tumor, patients are usually prescribed additional therapy to prevent or delay such recurrences. This additional therapy generally consists of immunotherapy or chemotherapy drugs instilled directly into the bladder. During the past 20 years or so, no new drugs have been introduced in the market for treatment of bladder cancer.
