(TSX: AEZ; NASDAQ: AEZS) today reported financial and operating results for the third quarter ended September 30, 2006. "The third quarter was marked by significant progress with the clinical development of our luteinizing hormone-releasing hormone (LHRH) antagonist compound, ozarelix, for which we disclosed positive Phase 2 results in both prostate cancer and benign prostatic hyperplasia," said Gilles Gagnon, AEterna Zentaris' President and Chief Executive Officer. "These very encouraging results enable us to pursue ozarelix's clinical development in both indications, moving forward with an ongoing Phase 2b trial in prostate cancer as well as the potential to initiate a late-stage program in benign prostatic hyperplasia in 2007. Furthermore, we granted Nippon Kayaku an exclusive license to develop and market ozarelix for all potential oncological indications in Japan. Additionally, we launched the first LHRH antagonist to enter the Japanese market, Cetrotide(R) (cetrorelix) for in vitro fertilization with our Japanese partners. We are pleased with these significant achievements as they clearly represent our commitment to aggressively move our product candidates through the pipeline and bring our lead compounds even closer to market." KEY DEVELOPMENTS FOR THE QUARTER ENDED SEPTEMBER 30, 2006 o POSITIVE PHASE 2 RESULTS FOR OZARELIX IN PROSTATE CANCER - The study achieved its primary end-point of defining a tolerable dosage regimen of ozarelix that would ensure continuous suppression of testosterone at castration level (< 0.5 ng/ml) for a three-month test period. The detailed results from the study will be presented at the upcoming SIU (SOCIETE INTERNATIONALE D'UROLOGIE) meeting in Cape Town, South Africa, on November 13, 2006. o POSITIVE PHASE 2 RESULTS FOR OZARELIX IN BENIGN PROSTATIC HYPERPLASIA (BPH) - With highly statistically significant positive data, the study achieved its primary efficacy end-point of improving clinical symptoms of BPH, at week 12, as measured by significant changes in the International Prostate Symptom Score (I-PSS), the standard method of assessing BPH symptoms. [AETERNA ZENTARIS LOGO] o PARTNERSHIP FOR OZARELIX IN JAPAN - AEterna Zentaris granted Nippon Kayaku an exclusive license to develop and market ozarelix for all potential oncological indications in Japan. O CETROTIDE(R)(CETRORELIX) LAUNCHED IN JAPAN FOR IN VITRO FERTILIZATION - Cetrotide(R)(cetrorelix), the first LHRH antagonist to enter the Japanese market, has been launched in Japan for IN VITRO fertilization. Cetrotide(R)(cetrorelix) is being manufactured and marketed in Japan by partners Nippon Kayaku Co., Ltd. and Shionogi & Co., Ltd. FINANCIAL RESULTS FOR THE QUARTER ENDED SEPTEMBER 30, 2006 Consolidated revenues for the quarter ended September 30, 2006 totalled $83.9 million compared to $52.9 million for the same period in 2005. Consolidated R&D expenses, net of tax credits and grants (R&D) remained steady during the third quarter at $6.2 million compared to $6.1 million for the same period in 2005. Consolidated selling, general and administrative (SG&A) expenses increased to $15.1 million for the quarter ended September 30, 2006 compared to $9.8 million for the same period in 2005. Consolidated net loss for the quarter ended September 30, 2006 was $6.5 million or $0.12 per basic and diluted share, compared to $3.8 million or $0.08 per basic and diluted share for the same period in 2005. The increase is mainly attributable to increased non-recurring corporate expenses and future income tax expense, partly offset by the increased contribution of Atrium. Cash, cash equivalents and short-term investments reached $45.8 million for the quarter ended September 30, 2006 compared to $52.7 million as of December 31, 2005. More than $25 million was dedicated to the Company's Biopharmaceutical segment as of September 30, 2006. Taking into account the sale of 24% of AEterna Zentaris' ownership interest in Atrium that occurred on October 18, 2006, AEterna Zentaris' pro-forma cash and short-term position dedicated to its Biopharmaceutical segment reached $71 million, compared to $34.8 million as of December 31, 2005. Dennis Turpin, Vice President and Chief Financial Officer of AEterna Zentaris, commented, "With a strong balance sheet, a controlled burn rate and a clear development strategy, we are well positioned to execute our business plan." DEVELOPMENTS SUBSEQUENT TO QUARTER END O CLOSING OF SECONDARY OFFERING OF AETERNA ZENTARIS' 3,485,000 SUBORDINATE VOTING SHARES OF ATRIUM BIOTECHNOLOGIES INC., AT A PRICE OF CDN$15.80 PER SHARE - In early January 2007, AEterna Zentaris intends, subject to receiving regulatory and other approvals, to distribute all of its remaining 11,052,996 subordinate voting shares of Atrium to its shareholders.
