Healthcare Industry News: ACAPODENE
News Release - June 22, 2006
In a Phase III Lipid Interim Analysis, ACAPODENE Treatment Lowered Cholesterol and Raised HDL In Prostate Cancer Patients On Androgen Deprivation TherapyMEMPHIS, Tenn., June 22 (HSMN NewsFeed) -- GTx, Inc. (Nasdaq: GTXI ), the Men's Health Biotech Company, announced today the results of a lipid interim analysis of the pivotal Phase III ADT clinical trial evaluating oral, once daily ACAPODENE® (toremifene citrate) 80mg for the treatment of the multiple serious side effects of androgen deprivation therapy (ADT) in men with advanced prostate cancer.
"Androgen deprivation therapy is quite effective in turning prostate cancer into a chronic disease in many patients," said Matthew R. Smith, M.D., Ph.D., Associate Professor of Medicine, Harvard Medical School. Dr. Smith is the lead Principal Investigator of the Phase III ADT clinical trial. "As patients are living longer with prostate cancer because of ADT, serious side effects have become major causes of morbidity and even death. These serious ADT side effects include osteoporosis and fractures as well as adverse lipid changes and cardiovascular disease. A medicine that is able to address multiple side effects of ADT would mark important progress in the care of prostate cancer patients."
GTx is conducting a pivotal Phase III clinical trial of ACAPODENE for the treatment of multiple serious side effects of ADT in approximately 1,400 men at over 150 sites in the United States and Mexico. The primary endpoint of the trial is a reduction in vertebral fractures. Secondary endpoints include improvements in bone mineral density (BMD), hot flashes, gynecomastia, and lipid profiles. Final data from the trial, which is being conducted under a Special Protocol Assessment with the United States Food & Drug Administration, is expected in the second half of 2007.
In December 2005, GTx conducted an interim analysis of the bone loss that leads to fractures which is another serious side effect of ADT. BMD was measured in the first 197 patients to complete one year of treatment. The per protocol analysis revealed highly statistically significant increases in BMD in all three skeletal sites assessed in patients receiving ACAPODENE compared to placebo: lumbar spine (+2.3%; p<0.001); hip (+2.0%; p=0.001); and femoral neck (+1.5%; p=0.009). The magnitude of these positive changes in BMD provides increased confidence that ACAPODENE should show efficacy in the trial's primary endpoint, a 40% reduction in vertebral fractures at two years.
"ACAPODENE has demonstrated the potential to increase bone mineral density, and the lipid interim analysis suggests that ACAPODENE may lower cholesterol," said Mitchell S. Steiner, M.D., CEO of GTx. "We continue to be confident in the Phase III ADT clinical trial. If ACAPODENE can treat multiple serious side effects of ADT, it has the potential to become the mainstay of prostate cancer supportive care for patients on ADT."
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 ACAPODENE® (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 ADT 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 also is developing ostarine, a selective androgen receptor modulator, or SARM, for a variety of indications including muscle wasting and bone loss in frail elderly patients, osteoporosis, muscle wasting in end stage renal disease patients, and severe burn wounds and associated muscle wasting. 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.
