AEterna Zentaris Reports 2006 First Quarter Financial And Operating Results

QUEBEC CITY, Canada, May 3 /PRNewswire-FirstCall/ - AEterna Zentaris Inc. today reported financial and operating results for the first quarter ended March 31, 2006. Consolidated revenues for the first quarter 2006 were $84.5 million, an increase of 36.5% compared to total revenues of $61.9 million for the same period in 2005. Consolidated R&D expenses net of tax credits amounted to $6.9 million for the first quarter of 2006 compared to $6.4 million for the same period in 2005. The Company’s consolidated net loss was $2.6 million for the first quarter of 2006, or $0.05 per share, compared to net earnings of $0.1 million for the same period in 2005. This $2.7 million variation is mainly attributable to a decrease in license revenues in the Company’s Biopharmaceutical segment, increased R&D investments and interest expense, partly offset by its 48.29%-owned subsidiary Atrium Biotechnologies’ net earnings. The consolidated cash and short-term investments were $46.9 million on March 31, 2006.

The Company highlighted first quarter 2006 advancements with respect to its product development pipeline, Corporate Affairs and recent events:

Product Development Pipeline Advancements - Initiation of Phase 2, Multi-Center study of perifosine for the treatment of refractory multiple myeloma; - Initiation of Phase 2, Multi-Center study of perifosine for the treatment of refractory leukemia; - Disclosure of preclinical results on various drug candidates at the American Association for Cancer Research (AACR) Meeting in Washington, including tubulin inhibitors, signal transduction inhibitors and cytotoxic conjugates; and - Regained the exclusive worldwide (ex-Japan) rights for cetrorelix in benign prostate hyperplasia. Corporate Affairs - The Solidarity Fund QFL and SGF Sante Inc. converted their term loans into common shares; - Former Abbott Vice President, Gerald J. Martin appointed to AEterna Zentaris Board. Recent Events - Gained market approval for Cetrotide(R) (cetrorelix) in Japan for in vitro fertilization.

Gilles Gagnon, AEterna Zentaris’ President and Chief Executive Officer said, “We progressed on multiple fronts throughout the quarter as we strengthened our financial position and continued to advance our development pipeline. The preclinical results on different anti-cancer agents presented at the American Association for Clinical Research (AACR) meeting in Washington, are indicative of the depth of our pipeline and its potential to yield novel products to treat cancer. Furthermore, we were very pleased to have regained the worldwide, ex-Japan rights for cetrorelix in BPH, and are presently in the process of designing a protocol to conduct a late-stage study with cetrorelix in BPH in the United States, upon discussions with the United States Food and Drug Administration. We believe we will initiate our late-stage development program this year, in line with our strategy. Finally, we continue to see progress with our lead signal transduction inhibitor, perifosine as two Phase 2 trials were initiated this quarter with our partner, Keryx, in leukemia and multiple myeloma. We are committed to driving our strategy forward as we aggressively move our promising product candidates through our pipeline.”

Dennis Turpin, Vice President and Chief Financial Officer of AEterna Zentaris, commented: “We were very pleased with SGF and FTQ’s decision to convert the entirety of their convertible term loans into AEterna Zentaris common shares. This conversion, along with Atrium’s continued growth, further strengthened our balance sheet in the first quarter. Furthermore, we will continue to see an increase in our R&D investment in 2006, clearly reflecting our commitment to our focused strategy to advance and expand our clinical- stage pipeline, in particular, the oncology proprietary products while maintaining a solid financial position.”
