GTx Provides Corporate Update and Reports Third Quarter 2015 Financial Results

MEMPHIS, Tenn.--(BUSINESS WIRE)--

GTx, Inc. GTXI today reported financial results for the quarter and nine months ended September 30, 2015, and highlighted recent accomplishments and developments. The Company's lead program has patients enrolling in two Phase 2 clinical trials of enobosarm: one in women with estrogen receptor positive (ER+) and androgen receptor positive (AR+) breast cancer, and another in women with AR+ triple negative breast cancer (TNBC).

In October, the Company received FDA clearance to initiate a Phase 2 proof-of-concept clinical trial of enobosarm to treat postmenopausal women with stress urinary incontinence (SUI) and plans to initiate the trial in the first quarter of 2016.

"While our primary focus continues to be the development of enobosarm to treat advanced breast cancer, we are expanding the potential utility of our SARM portfolio with the initiation of a proof of concept trial in SUI," said Dr. Robert J. Wills, Executive Chairman of GTx. "Together with our preclinical development in Duchenne muscular dystrophy, we hope to leverage other SARM compounds in our portfolio to create near term value for indications outside of oncology."

Corporate Highlights

Enobosarm, a selective androgen receptor modulator (SARM), is the Company's lead product candidate and is being developed as a targeted treatment for two advanced breast cancer indications for (i) estrogen receptor positive (ER+) and androgen receptor positive (AR+) breast cancer, and (ii) AR+ triple negative breast cancer (TNBC). For both clinical studies, the primary efficacy objective will be clinical benefit, which is defined as a complete response, partial response or stable disease. Preliminary data from the first stage of both Phase 2 clinical trials are expected by the end of 2016.

• Initiated enrollment of an open-label, Phase 2 clinical trial of enobosarm to assess clinical benefit in women with metastatic or locally advanced, ER+/AR+ breast cancer. The study will enroll up to 118 patients to obtain data from 88 evaluable patients to assess the primary efficacy objective of clinical benefit following 24 weeks of treatment.
• Initiated enrollment of an open-label, proof-of-concept Phase 2 clinical trial of enobosarm in women with advanced AR+ TNBC. The study will enroll up to 55 patients to obtain data from 41 evaluable patients to assess the primary efficacy objective of clinical benefit following 16 weeks of treatment.

SARMs ability to increase muscle mass may prove beneficial in other non-oncology indications. The Company is exploring SARMs as potential treatments for stress urinary incontinence (SUI) in postmenopausal women where pelvic floor muscle weakness leads to incontinence, as well as Duchenne muscular dystrophy (DMD), a rare genetic disorder characterized by progressive muscle degeneration and weakness.

• The FDA has accepted the investigational new drug (IND) application for a Phase 2 proof-of-concept clinical trial of enobosarm to treat postmenopausal women with SUI. The Company plans to initiate the trial in the first quarter of 2016 and anticipates top-line data by the end of 2016.
• The Company's preclinical studies have continued to confirm beneficial effects from SARMs in mice genetically altered to simulate DMD, compared to control groups. DMD mice were treated with three different SARM compounds, including enobosarm, and each cohort demonstrated increases in body weight, muscle mass, muscle performance (grip strength) and cardiac function compared to control groups. The Company has initiated discussions with potential strategic partners who have proven experience in developing and commercializing therapies for DMD.

Selective Androgen Receptor Degrader (SARD) technology is being evaluated as a potentially novel treatment for men with castration-resistant prostate cancer, including those who do not respond or are resistant to currently approved therapies. The Company believes that its SARD compounds will degrade multiple forms of the androgen receptor, including AR variants, such as AR-V7.

• The Company continues to make progress towards identifying potential clinical SARD candidates with the goal of initiating preclinical studies in the first quarter of 2016.

Forward-Looking Information is Subject to Risk and Uncertainty

This press release contains forward-looking statements based upon GTx's current expectations. Forward-looking statements involve risks and uncertainties, and include, but are not limited to, statements relating to the commencement and enrollment of GTx's planned clinical study of enobosarm (GTx-024) to treat stress urinary incontinence (SUI) and GTx's ongoing Phase 2 clinical trials of enobosarm for the treatment of advanced breast cancer, as well as the potential preclinical and other future development of GTx's licensed SARD technology and the development of selective androgen receptor modulators (SARMs) for the treatment of Duchenne muscular dystrophy (DMD) and the timing thereof, including the anticipated identification of clinical SARD candidates and the potential evaluation thereof in clinical studies; the potential therapeutic applications for, and potential benefits of SARM (including enobosarm) and SARD technology; and GTx's expectation that it will recognize non-cash gains or losses resulting from the revaluation of the warrants issued in November 2014 to fair value each reporting period through the earlier of December 31, 2016 or the exercise in full of these warrants. 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 (i) that GTx's evaluation of the licensed SARD technology or a SARM for the treatment of DMD are at very early stages and it is possible that GTx may determine not to move forward with any meaningful development of one or both programs; (ii) that even if GTx does determine to move forward with meaningful development of its SARD program or a SARM for the treatment of DMD, to advance preclinical development of its SARD or SARM program sufficient to support the initiation of clinical studies, GTx will require additional funding, which it may be unable to raise, in which case, GTx may fail to realize the anticipated benefits of its licensing of the SARD and/or SARM technology; (iii) that GTx may not be successful in developing a clinical SARD product candidate or a SARM for the treatment of DMD to advance into clinical studies or the clinical product candidate may fail such clinical studies; (iv) that the clinical trials of enobosarm to treat advanced breast cancer being conducted by GTx or the planned clinical trial of enobosarm to be conducted by GTx in SUI may not be initiated or completed on schedule, or at all, or may otherwise be suspended or terminated; (v) related to the difficulty and uncertainty of pharmaceutical product development, including the time and expense required to conduct preclinical and clinical trials and analyze data, and the uncertainty of preclinical and clinical success; (vi) related to issues arising during the uncertain and time-consuming regulatory process, including the risk that GTx may not receive any approvals to advance the clinical development of one or more potential clinical SARM or SARD candidates; (vii) that any additional clinical development of GTx's product candidates beyond the Phase 2 clinical trials of enobosarm for the treatment of advanced breast cancer or the planned Phase 2 clinical trial of enobosarm for the treatment of SUI is contingent on GTx entering into new collaborative arrangements with third parties for such development or otherwise obtaining sufficient additional capital to permit such development, which it may be unable to do; (viii) that GTx may be unsuccessful in developing any third party interest in partnering or acquiring a SARM for the treatment of DMD or SUI, in which case GTx may be forced to abandon the development of a SARM for the treatment of DMD and/or SUI and may otherwise not receive any return on its investment for these SARM compounds; and (ix) that GTx could remain subject to liability accounting with respect to the November 2014 warrants for the full terms of these warrants. In addition, GTx will continue to need additional funding and may be unable to raise capital when needed, which would force GTx to delay, reduce or eliminate its product candidate development programs and potentially cease operations. 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. 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 for the quarter ended June 30, 2015 contains under the heading, "Risk Factors", a more comprehensive description of these and other risks to which GTx is subject. GTx expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in its expectations with regard thereto or any change in events, conditions or circumstances on which any such statements are based.
