AETERNA ZENTARIS REPORTS 2006 THIRD QUARTER RESULTS


QUARTER MARKED BY SIGNIFICANT ADVANCEMENTS WITH LHRH ANTAGONIST PLATFORM

ALL AMOUNTS ARE IN U.S. DOLLARS

QUEBEC CITY, CANADA, NOVEMBER 13, 2006 -AEterna Zentaris Inc. (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.

     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

          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.

Gilles Gagnon, President and Chief Executive Officer at AEterna Zentaris
concluded, "Over the past few months, we have successfully achieved major
milestones. We now look forward to continuing this great momentum for the
remainder of the year and emerge in early 2007 as a late-stage pure play
biopharmaceutical company, in an effort to further unlock value to our
shareholders."
