GTx Announces Additional Top Line Phase III Data Demonstrating Toremifene Citrate 80 mg Reduced Hot Flashes in Men with Prostate Cancer on Androgen Deprivation TherapyThe Most Common Symptomatic Side Effect Experienced by Men on ADT is Hot Flashes
MEMPHIS, Tenn.--(HSMN NewsFeed)--GTx, Inc. (NASDAQ: GTXI ) today announced that toremifene citrate 80 mg reduced hot flashes in men with prostate cancer on androgen deprivation therapy (ADT), a key secondary endpoint of the Phase III clinical trial evaluating toremifene citrate 80 mg for the treatment of multiple side effects of ADT for advanced prostate cancer.
“Hot flashes are the most common and bothersome symptomatic side effect of ADT. Up to 80% of men on ADT report being troubled by hot flashes, which are often cited as a cause of noncompliance with hormone therapy,” said Matthew R. Smith, MD, PhD, Director, Genitourinary Medical Oncology, Massachusetts General Hospital Cancer Center, Associate Professor of Medicine at Harvard Medical School, and Lead Principal Investigator of the Phase III ADT clinical trial.
GTx earlier announced data from the Phase III ADT clinical trial demonstrating that toremifene citrate 80 mg reduced new morphometric vertebral fractures, the primary endpoint of the trial, and met other key endpoints, including increasing bone mineral density, improving lipid profiles, and ameliorating gynecomastia.
“The Phase III ADT clinical trial data are important because they demonstrate the potential for toremifene citrate 80 mg as a treatment for multiple side effects of ADT, reducing fractures and improving lipid profiles while also treating symptomatic side effects such as hot flashes and gynecomastia,” added Dr. Smith.
“These hot flashes data provide additional confirmation that the multiple estrogen related side effects of androgen deprivation therapy for prostate cancer are treatable by toremifene citrate 80 mg, which binds to and selectively modulates the estrogen receptor depending on tissue type,” said Mitchell S. Steiner, MD, Chief Executive Officer of GTx.
toremifene citrate 80 mg had a favorable safety profile and was well tolerated. Among the most common adverse events that occurred were joint pain (treated 7.3%, placebo 11.8%), dizziness (treated 6.3%, placebo 5.0%), back pain (treated 5.9%, placebo 5.2%), and extremity pain (treated 5.0%, placebo 4.4%).

GTx, Inc., headquartered in Memphis, Tenn., is a biopharmaceutical company dedicated to the discovery, development, and commercialization of small molecules that selectively target hormone pathways to treat cancer, osteoporosis and bone loss, muscle wasting and other serious medical conditions.
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 evaluating toremifene citrate 80 mg for the treatment of serious side effects of androgen deprivation therapy for advanced prostate cancer, and second, a pivotal Phase III clinical trial evaluating toremifene citrate 20 mg for the prevention of prostate cancer in high risk men with high grade prostatic intraepithelial neoplasia, or PIN.
GTx licensed from Orion Corporation the rights to toremifene citrate for all indications worldwide, except breast cancer outside the United States. In 2006, GTx and Ipsen Group entered into a development and collaboration agreement for toremifene citrate in all indications except breast cancer for Europe and the Commonwealth of Independent States (CIS). Ipsen is the leading marketer of ADT (triptorelin) in Europe. Under the agreement, Ipsen will be responsible for filing for marketing approval with regulatory authorities and commercializing toremifene citrate in Europe and CIS. GTx will file for marketing approval and plans to commercialize toremifene citrate 80 mg in the United States.
GTx has formed a strategic collaboration with Merck & Co., Inc. for the development and global commercialization of selective androgen receptor modulators, or SARMs, a new class of drugs with the potential to treat a variety of indications associated with muscle wasting and bone loss, including frailty or sarcopenia, muscle wasting associated with chronic diseases, osteoporosis, and cancer cachexia. GTx also has announced that it is developing its preclinical compounds, GTx-758, an oral LH inhibitor for advanced prostate cancer, and GTx-878, an estrogen receptor beta agonist for the treatment of benign prostatic hyperplasia and chronic prostatitis.
