AETERNA ZENTARIS ANNOUNCES OUTCOME OF MANAGEMENT'S STRATEGIC REVIEW

QUEBEC CITY, CANADA, OCTOBER 2, 2007 - AEterna Zentaris Inc. (TSX: AEZ; Nasdaq:
AEZS), a global biopharmaceutical company focused on endocrine therapy and
oncology, will announce today at 11:00 a.m. Eastern Time, during a live
webcast presentation and conference call hosted by President and Chief Executive
Officer, David J. Mazzo, Ph.D., the outcome of management's review of the
Company's pipeline and business operations along with key elements of the new
strategic plan implemented to achieve short-term and long-term success.

David J. Mazzo, President and Chief Executive Officer of AEterna Zentaris
stated, "Over the past four months, our Executive Team has been tasked with
completing a thorough review of our extensive pipeline and business operations
with the goal of creating a strategy optimized for success. As a result of this
extensive exercise, we established a harmonized global vision and elucidated our
strategic imperatives. Based on a rigorous assessment of the value of our
assets, our abilities and resources, the probability of success and return on
investment potential of each of our product candidates and our objective to
maximize shareholder value, we additionally established a set of priorities and
plans to achieve our vision."

During the live webcast, the company will discuss in detail the following
fundamentals of their strategic plan .

/ /      AEterna Zentaris is now a multinational company with a clear vision to
         eventually become a fully integrated biopharmaceutical company (without
         commercial manufacturing). The necessary resources have been identified
         and allocated to achieve business success.

/ /      AEterna Zentaris has prioritized its pipeline, developed a partnering
         strategy and determined the value of its most immediate assets:

                  Cetrorelix

                  Cetrorelix, currently in a Phase 3 program for benign
                  prostatic hyperplasia (BPH), is clearly the Company's highest
                  priority, being the asset with the largest combination of
                  probability of success, proximity to launch and potential
                  medical and commercial value. The Company has decided to seek
                  a commercialization partner for cetrorelix, which, in this
                  indication, has potential for base case peak annual sales of
                  over $500 million in the United States market alone. After
                  defining




                                                         [AETERNA ZENTARIS LOGO]

                  the critical path to registration, the Company expects to
                  launch cetrorelix in the BPH indication in 2011.

                  Furthermore, after optimization of formulation and trial
                  design, the company plans to move into Phase 2b in the
                  endometriosis indication and will announce timelines relative
                  to this program in the near future. As was announced in May
                  2007, the rights to cetrorelix in the endometriosis indication
                  were regained from Solvay. The decision to proceed with
                  development was made based on:

                        a)   the proven safety and efficacy of Cetrotide(R)
                        b)   the overall database from preclinical and clinical
                             studies in endometriosis
                        c)   the large unmet medical needs and commercial
                             opportunity in the area of endometriosis.

                  Additionally, as with the BPH indication, AEterna Zentaris
                  will eventually seek a commercialization partner as cetrorelix
                  has the potential for base case peak annual sales of
                  approximately $200 million in the U.S. market alone in the
                  endometriosis indication.

                  AEZS-108

                  AEterna Zentaris has established its cytotoxic conjugate,
                  AEZS-108, as its highest earlier-stage priority, and will
                  therefore initiate a Phase 2 trial with this compound in a
                  both endometrial and ovarian cancers before year end. The
                  Company feels AEZS-108 has large market opportunities that
                  could compare to those for doxorubicin.

/ /      The Company provided clarity regarding its partnered development
         programs. The Company will minimize internal spend on partnered
         programs while continuing to respect its contractual obligations to
         support its partners for the development of ozarelix, perifosine,
         AEZS-127 and AEZS-130. AEterna Zentaris will employ a "piggy back"
         registration strategy to bring these products to market in the
         territories where is retains rights as commercial opportunity size
         dictates.

/ /      The Company prioritized the advancement of preclinical and very
         early-stage development programs based on risk-adjusted maximum market
         potential.

/ /      The Company established a clear global partnering strategy moving
         forward:

               -   All commercially viable projects will be ideally developed
                   internally through proof-of-concept in man;

               -   Asia (especially Japan) remains a market of interest
                   for AEZS.

/ /      The Company also identified non-core assets and will actively seek to
         monetize/divest these assets as a potential source of non-dilutive
         funding.

/ /      The Company provided updated guidance for the 2007 total expected burn
         in a range of $25-$27 million. Additionally, in an effort to ensure
         financial flexibility, the Company recently filed a shelf prospectus.

"It has been our guiding principle to communicate the complete picture of
AEterna Zentaris as it is and as it is planned to be with updated timelines,
priorities, key issues and expectations. After a rigorous review of the
projects, risks, plans and commercial opportunities, we are more bullish than
ever about the unrealized intrinsic value of AEZS and our ability to unlock it
to the benefit of patients and shareholders," concluded Dr. Mazzo.
