The FDA identified two deficiencies in the Complete Response Letter and recommended that the following information be provided to the FDA to address these clinical deficiencies: (i) results of a second adequate and well controlled Phase III trial demonstrating the safety and efficacy of toremifene citrate 80mg to reduce fractures in men with prostate cancer on ADT and (ii) results from an adequate and well-controlled clinical trial demonstrating that toremifene treatment to reduce fractures in men with prostate cancer on ADT does not have a detrimental effect on either time-to-disease progression or overall survival. GTx is requesting a meeting with the FDA to determine the appropriate next steps regarding the NDA.

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 prevent and treat cancer, fractures and bone loss, muscle loss and other serious medical conditions. GTx is pursuing marketing approval in the United States for toremifene 80 mg to reduce fractures in men with prostate cancer on ADT. GTx is also developing toremifene 20 mg in an ongoing pivotal Phase III clinical trial for the prevention of prostate cancer in high risk men with high grade prostatic intraepithelial neoplasia. GTx has licensed to Ipsen Developments Limited exclusive rights in the European Union, Switzerland, Norway, Iceland, Lichtenstein, and the Commonwealth of Independent States to develop and commercialize toremifene for all indications which GTx has licensed from Orion Corporation. In December 2007, GTx and Merck & Co., Inc. entered into a collaboration to discover and develop selective androgen receptor modulators, or SARMs, a new class of drugs with the potential to treat chronic sarcopenia, which is the loss of skeletal muscle mass resulting in reduced physical strength and ability to perform activities of daily living and other musculoskeletal wasting or muscle loss conditions, including muscle loss in patients with chronic obstructive pulmonary disease. GTx and Merck are evaluating multiple SARM product candidates, including OstarineTM (designated by Merck as MK-2866) and MK-0773, for a variety of musculoskeletal wasting indications. GTx is also developing GTx-758, an oral luteinizing hormone inhibitor for the treatment of advanced prostate cancer.
Forward-Looking Information is Subject to Risk and Uncertainty
This press release contains forward-looking statements based upon GTx's current expectation, including but not limited to statements relating to GTx's plans to continue to pursue marketing approval for toremifene 80 mg and the continued development of GTx's other product candidates. Forward-looking statements involve risks and uncertainties. GTx's actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, which include, without limitation, the risks that (i) GTx and its collaboration partners will not be able to commercialize their product candidates if clinical trials do not demonstrate safety and efficacy in humans, including in any additional clinical trials required by the FDA in connection with the NDA for toremifene 80 mg to reduce fractures in men with prostate cancer on ADT; (ii) GTx may not be able to obtain required regulatory approvals to commercialize its product candidates, including toremifene 80 mg to reduce fractures in men with prostate cancer on ADT, in a timely manner or at all; (iii) clinical trials being conducted by GTx and its collaboration partners may not be completed on schedule, or at all, or may otherwise be suspended or terminated; and (iv) GTx could utilize its available cash resources sooner than it currently expects and may be unable to raise capital when needed, which would force GTx to delay, reduce or eliminate its product development programs or commercialization efforts. You should not place undue reliance on these forward-looking statements, which apply only as of the date of this press release. GTx's quarterly report on Form 10-Q filed August 10, 2009 contains under the heading, "Risk Factors," a more comprehensive description of these and other risks to which GTx is subject.
