Ipsen and GTx Enter into Partnership Agreement for The European Rights of Acapodene(R)

GTx Conference Call & Webcast Today at 9:00 a.m. Eastern Time

PARIS & MEMPHIS, Tenn.--(HSMN NewsFeed)--Sept. 7, 2006--Ipsen, a European pharmaceutical group (Paris: IPN ) and GTx, Inc. (Nasdaq: GTxI ), the Men's Health Biotech Company announced today that they have entered into a definitive agreement under which Ipsen will have an exclusive license to develop and market GTx's Acapodene® (toremifene citrate) in all indications except breast cancer, in Europe (European Union, Switzerland, Norway, Iceland, Lichtenstein and the Commonwealth of Independent States) ("European Territory").

Acapodene®, a selective estrogen receptor modulator (SERM), is intended to exploit a new strategy of estrogen receptors modulation which could translate into a tangible clinical benefit in both the chemoprevention of prostate cancer in high-risk men and the treatment of multiple side effects from androgen deprivation therapy in advanced prostate cancer.

Acapodene® is currently being developed in separate pivotal Phase III clinical trials for two indications. The first indication is for the treatment of multiple side effects of androgen deprivation therapy (ADT) for advanced prostate cancer (80 mg dose). Final data from the ADT trial is expected in the second half of 2007 with an anticipated New Drug Application filing in the US in 2008. The second indication is for the prevention of prostate cancer in men with high grade prostatic intraepithelial neoplasia (HGPIN)(20 mg dose). GTx expects to conduct an interim efficacy analysis between the second half of 2007 and first quarter of 2008 for the HGPIN indication. If the statistical parameters are achieved, GTx will proceed with the filing of a New Drug Application in the US.

Ipsen will pay to GTx EUR 23 million (approximately $30 million based on current exchange rates) upfront payment and fees. In addition, GTx may receive milestone payments from Ipsen of EUR 39 million ($50 million) for Acapodene®, depending on the successful development and European launch of Acapodene® and subject to certain conditions for HGPIN: up to EUR 9 million ($12 million) for the ADT Indication, up to EUR 20 million ($26 million) for the HGPIN Indication and up to EUR 10 million ($13 million) as additional milestone payments. As from execution of the agreement, Ipsen will pay all clinical development, regulatory and launch expenses to commercialize Acapodene® in the European Territory. Ipsen may pay a portion of GTx's Acapodene® development costs in the U.S. if certain conditions are met. Ipsen has agreed to pay GTx a graduating royalty on net sales in the mid-teens which could reach the mid-twenties based on certain sales price thresholds being met. GTx is responsible for paying upstream royalties for Acapodene®. Ipsen will procure the bulk material from a third party and is responsible for the secondary manufacturing of the product.

"We are excited to enter into a partnership with Ipsen for European rights to Acapodene®," said Mitchell S. Steiner, M.D., Chief Executive Officer of GTx. "Ipsen has an extensive track record of drug development and commercialization in Europe and has specific expertise marketing to urologists and oncologists. This partnership allows GTx to maintain its rights to Acapodene® in the United States, where we will build a sales force to market it to urologists and medical oncologists," Steiner said. "The upfront payment will add sufficient cash on our balance sheet to last through the first quarter of 2008, which is beyond the time when we expect to see data from both of our pivotal Phase III Acapodene® trials."

"This partnership with GTx regarding Acapodene®, a product for prostate cancer prevention and for the treatment of side effects of ADT, will further expand Ipsen's franchise of oncology products, one of our targeted therapeutic areas," said Jean-Luc Belingard, Chairman and CEO of the Ipsen Group. "It confirms Ipsen's positioning in the treatment of hormone-dependent diseases, both in oncology and endocrinology and broadens the range of our prostate cancer related product portfolio."

Acapodene®

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® in an 80 mg dose for the treatment of multiple side effects of ADT for advanced 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 (FDA). The primary endpoint of the trial is a reduction in vertebral 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 bone mineral density 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 197 patients. Patients treated with Acapodene® had statistically significantly lower levels of total cholesterol, Low Density Lipoproteins (LDL), and triglycerides, a reduction in the ratio of total cholesterol to High Density Lipoproteins (HDL), and higher HDL, when compared to patients on placebo. The full lipid data set will be evaluated before conclusions about clinical significance of the findings can be drawn. 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® in a 20 mg dose for the prevention of prostate cancer in men with high grade PIN. More than 1,300 patients with high grade PIN are enrolled in the trial, which is being conducted under a SPA with the FDA. The primary endpoint of the trial is a reduction in the incidence of prostate cancer. GTx expects to conduct an interim efficacy analysis between the second half of 2007 and the first quarter of 2008. If the requisite statistical parameters are achieved, GTx will proceed with the filing of a New Drug Application.

GTx is developing Acapodene® (toremifene citrate), a selective estrogen receptor modulator (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. Orion Pharma is supplying Acapodene® under its license and supply agreement with GTx. 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 second half of 2006.

Ipsen in oncology

Oncology is a key driver for the future of the Ipsen Group, and is also one of its targeted therapeutic area. Ipsen's leading product, Decapeptyl®, a GnRH analogue used in androgen deprivation therapy for prostate cancer, had 2005 sales of EUR 211 million. Ipsen's technology programmes in peptide and protein engineering and medicinal chemistry enable it to explore and develop new approaches in cancer treatment under hormonal control, e.g. like with steroids, growth factors and enzymes regulating cell cycle. For instance:
  • Decapeptyl®, a decapeptide analogue of GnRH, a hormone secreted by the hypothalamus, paradoxically act as castration agent in diseases induced by sexual hormones. Decapeptyl® is marketed in monthly or quarterly sustained release formulations, as well as in a daily formulation. Ipsen is developing sustained-release formulations of Decapeptyl® for treatment durations longer than three months and is conducting phase III clinical trials with this product in combination with an aromatase inhibitor in the treatment of breast cancer in premenopausal women.
  • BN 83495, a first in class steroid sulfatase inhibitor, is tested in a phase I trial in the treatment of postmenopausal women with breast cancer.
  • BN 2629, a DNA minor groove binding agent, is being studied in 3 phase I trials in patients with metastatic refractory solid tumours and leukemias.
  • Two patented cytotoxic agents, diflomotecan and elomotecan are respectively in phase II and I clinical trials are being tested in metastatic cancers.
