Spectrum Pharmaceuticals Announces Phase 2 Data For Ozarelix In Hormone-Dependent Prostate Cancer
Spectrum
Pharmaceuticals, Inc. (Nasdaq: SPPI) today announced data from its Phase 2
trial with ozarelix for patients suffering from hormone-dependent prostate
cancer.
In this study, ozarelix was administered intramuscularly in 65, 100 or
130 mg according to different dosing schedules and repeated for 3 cycles of
28 days. The total dose by patient during the study ranged from 230 mg to
390 mg. Patients receiving doses of 130 mg per cycle of ozarelix have shown
the greatest continuous suppression of testosterone, the primary endpoint,
where patients remained suppressed to castration until at least day 85. In
patients with continuous testosterone suppression, tumor response as
measured by PSA levels, was 97%. Ozarelix was well tolerated at all
dosages. Full detailed results from the complete Phase 2 study will be
presented at the upcoming Societe Internationale d'Urologie (SIU) meeting
to be held in Cape Town, South Africa on November 12-16, 2006.
This trial is an open-label Phase 2 trial evaluating different
intramuscular dosage regimens of the Luteinizing Hormone Releasing Hormone
(LHRH) antagonist, ozarelix, to assess its safety and efficacy. This
study's primary endpoint is to define the most tolerable dosage regimen of
ozarelix that would ensure continuous suppression of testosterone at
castration levels (< 0.5 ng/mL) for a three month test period. Ozarelix's
effect on tumor responses are determined by assessing serum PSA response,
determined as a 50% or greater reduction of serum PSA levels, compared to
baseline. The trial is being conducted in Europe in collaboration with
Spectrum's partner, AEterna Zentaris (Nasdaq: AEZS; Toronto: AEZ), and has
enrolled 64 patients. An additional study, which will evaluate an
additional 32 patients, has been initiated at other European clinical
sites.
"We are encouraged by the safety and efficacy results demonstrated in
the trial thus far," stated Raj C. Shrotriya, M.D., Chairman, President and
Chief Executive Officer of Spectrum Pharmaceuticals. "Ozarelix demonstrates
the depth of our pipeline behind our other three late-stage opportunities
that include Satraplatin, LFA and EOquin."

Canada and Mexico) and India. In addition, Spectrum will share with AEterna
Zentaris upfront and milestone payments, royalties or profits from sales of
the product in Japan.
