Spectrum Pharmaceuticals Announces FDA's Acceptance of Ozarelix IND and Approval of Phase 2b Protocol in BPH (Benign Prostate Hypertrophy)Spectrum to initiate the study in approximately 100 patients in January 2007
Spectrum on track to initiate pivotal Phase 3 trials in the second half of 2007, which will evaluate long term efficacy and safety of ozarelix courses given at 6-month intervals
IRVINE, Calif., Jan. 3 (HSMN NewsFeed) -- Spectrum Pharmaceuticals, Inc. (Nasdaq: SPPI ) announced today that the U.S. Food and Drug Administration (FDA) has accepted the Company's Investigational New Drug (IND) application for ozarelix in Benign Prostate Hypertrophy (BPH) and that the FDA has approved the protocol for the Phase 2b study of ozarelix for the treatment of BPH. Dr. Claus Roehrborn from the UT Southwestern Medical Center at Dallas, Department of Urology, will serve as the lead investigator.
The Phase 2b study is a randomized, placebo-controlled trial of ozarelix involving approximately 100 men suffering from BPH. In this trial, the men will be dosed with 15 mg of ozarelix or placebo on day 1 and day 15 and will be followed for 6 months following dosing. The study will evaluate safety and assess the clinical efficacy of ozarelix as a treatment for BPH. The primary endpoint of the study will be the improvement of BPH symptoms as measured by the International Prostate Symptom Score (IPSS), the standard method of assessing BPH symptoms. The study will also measure urine flow, residual urine volume and quality of life. This trial will begin in January 2007 and data from this trial is expected to be available in approximately six months time after the trial is initiated. Safety and efficacy data from this trial will be used to support a New Drug Application (NDA) for ozarelix.
"This trial will enable clinical investigators to familiarize themselves with ozarelix prior to the start of the pivotal Phase 3 trials, which are scheduled to begin in the second half of 2007," stated Rajesh Shrotriya, M.D., Chairman, President and CEO of Spectrum Pharmaceuticals. "We are very pleased that Dr. Roehrborn, an internationally recognized leader in the diagnosis and treatment of BPH, has agreed to serve as the lead investigator for this and subsequent trials as his knowledge and expertise in BPH will be invaluable."
Earlier this year, Spectrum reported results from a double-blinded, randomized, placebo-controlled, multi-center, dose ranging Phase 2 trial with ozarelix in patients suffering from BPH. While the primary efficacy endpoint was achieved at all dosage regimens in this trial and ozarelix was well tolerated, the best results were obtained with the 15 mg dose, in terms of improvement in the IPSS score. Importantly, with this dosage regimen, where the patient is dosed on day 1 and day 15, the clinical efficacy was maintained for 6 months. Current therapies require the patient to be dosed daily. Using the 15 mg dose, the observed mean decrease in the IPSS score at weeks 12, 20 and 28 were -8.6, -9.4 and -8.7, respectively (mean: 47% decrease from baseline). This improvement in the IPSS represented a highly statistically significant and clinically meaningful difference versus baseline (p<0.001) as well as versus placebo (p<0.0001).
About Ozarelix and Development Alliance with Aeterna Zentaris
Ozarelix is a fourth generation Luteinizing Hormone Releasing Hormone (LHRH) antagonist administered as an intramuscular injection. In August 2004, Spectrum received an exclusive license from Aeterna Zentaris to develop and market ozarelix for all potential indications in North America (including Canada and Mexico) and India.
In addition, Spectrum will receive 50 percent of any upfront and milestone payments, royalties and/or profits from sales of the product in Japan. Japanese rights for all potential oncology indications have recently been licensed to Nippon Kayaku, a key player in the Japanese oncology market.
Spectrum is developing ozarelix for benign prostatic hypertrophy (BPH), hormone-dependent prostate cancer and other indications.
About Benign Prostatic Hypertrophy
Benign prostatic hypertrophy is a non-cancerous enlargement of the prostate frequently occurring in men over the age of 50. According to the National Institutes of Health, BPH affects more than 50% of men over the age of 60 and as many as 90% of men over the age of 70 and it is estimated that there are currently more than 28 million men suffering from BPH in the United States.
The IPSS (also known as AUA symptom index) is a standardized scoring system which evaluates the seven principal symptoms of BPH. The enlargement can result in the gradual squeezing of the urethra, resulting in increased frequency or difficulty in urinating. Treatment options for BPH include surgery and medications to reduce the amount of tissue and increase the flow of urine. Current treatment options have limited efficacy, leading to inadequate compliance. Medications currently available belong to two classes: alpha blockers (such as FLOMAX®, CARDURA® and HYTRIN®) which relax the muscles in the neck of the bladder and in the prostate, but have no direct effect on the prostate growth itself, and alpha reductase inhibitors (such as PROSCAR® and AVODART®), which can result in some reduction of the prostate size but have a very slow onset of action, and may be associated with impotence and decreased libido.
