GTx's Phase III Clinical Development of ACAPODENE on Course Following Planned Safety ReviewMEMPHIS, Tenn., Sept. 5 (HSMN NewsFeed) -- GTx, Inc. (Nasdaq: GTXI ), the Men's Health Biotech Company, today announced that a per protocol interim safety review by an independent Drug Safety Monitoring Board (DSMB) recommended that GTx continue clinical development as planned with its two pivotal Phase III trials of ACAPODENEŽ (toremifene citrate). The DSMB meets regularly every six months to review unblinded safety data from the two pivotal Phase III clinical trials.
"The DSMB reviewed safety data of more than 2,700 patients enrolled in our two pivotal Phase III trials and recommended that GTx continue with the trials as planned. This welcome news reduces the risk in ACAPODENE's clinical development and improves the prospects that we will be able to submit these product candidates for marketing approval," said Mitchell Steiner, MD, Chief Executive Officer of GTx.
GTx is developing ACAPODENE in two pivotal Phase III clinical trials for two separate indications in men. GTx is conducting a pivotal Phase III clinical trial evaluating ACAPODENE 80 mg for the treatment of multiple side effects of androgen deprivation therapy for prostate cancer. Approximately 1,400 patients are participating in the trial, which is being conducted under a Special Protocol Assessment (SPA) with the United States Food & Drug Administration. The primary endpoint of the trial is a reduction in fractures. Other endpoints include improvements in bone mineral density (BMD), hot flashes, lipid profiles, and gynecomastia. In December 2005, GTx conducted a planned interim analysis of BMD in the first 197 patients to complete a full year of treatment. In each of three measurements (lumbar spine, hip and femoral neck), highly statistically significant positive changes in BMD were observed in patients on ACAPODENE, when compared to patients on placebo, who on average lost bone. In June 2006, GTx conducted a lipid interim analysis of the same cohort of patients. Patients treated with ACAPODENE had statistically significantly lower levels of total cholesterol, LDL, and triglycerides, a reduction in the ratio of total cholesterol to HDL, and higher HDL, when compared to patients on placebo. GTx expects to receive final data from the trial in the second half of 2007.
GTx is conducting a separate pivotal Phase III clinical trial evaluating ACAPODENE 20 mg for the prevention of prostate cancer in men with high grade prostatic intraepithelial neoplasia (PIN). More than 1,340 patients with high grade PIN are enrolled in the trial, which is being conducted under a SPA with the FDA. The endpoint of the trial is a reduction in prostate cancer incidence. GTx expects to conduct an interim efficacy analysis between the fourth quarter of 2007 and the first quarter of 2008. If the statistical parameters are achieved, GTx will proceed with the filing of a New Drug Application.
GTx, headquartered in Memphis, Tenn., is a biopharmaceutical company dedicated to the discovery, development and commercialization of therapeutics for cancer and serious conditions related to men's health. GTx's lead drug discovery and development programs are focused on small molecules that selectively modulate the effects of estrogens and androgens, two essential classes of hormones. GTx is developing ACAPODENEŽ (toremifene citrate), a selective estrogen receptor modulator, or SERM, in two separate clinical programs in men: first, a pivotal Phase III clinical trial for the treatment of serious side effects of androgen deprivation therapy for advanced prostate cancer, and second, a pivotal Phase III clinical trial for the prevention of prostate cancer in high risk men with high grade prostatic intraepithelial neoplasia, or PIN. GTx is developing ostarine, a selective androgen receptor modulator, or SARM, for muscle wasting and bone loss indications. Ostarine is currently being evaluated in a Phase II clinical trial in 120 elderly men and postmenopausal women. GTx expects to have data from the Phase II ostarine trial in the fourth quarter of 2006. GTx has licensed to Ortho Biotech Products, L.P., a subsidiary of Johnson & Johnson, another of its SARMs, andarine, under a joint collaboration and license agreement.
