     clinical development plan

                                                                   PRESS RELEASE
                                                           FOR IMMEDIATE RELEASE

              AETERNA UPDATES NEOVATAT'S CLINICAL DEVELOPMENT PLAN


ALL AMOUNTS ARE IN CANADIAN DOLLARS

QUEBEC CITY, QUEBEC, DECEMBER 17, 2003 -- Gilles Gagnon, President and Chief
Executive Officer at AEterna Laboratories Inc. (TSX: AEL; Nasdaq: AELA) today
presented the Company's updated plan on the clinical development of Neovastat.
This plan includes the continuation of the Phase III trial in non-small cell
lung cancer sponsored by the U.S. National Cancer Institute (NCI) with which
AEterna has just renewed the agreement for a period of two years. Also, for
strategic considerations, AEterna ceases all activities related to renal cell
carcinoma, resulting in a workforce reduction. These decisions are based upon
management's evaluation of the recommendations of an international committee of
six oncology experts, combined with an extensive analysis of the development
plan for AEterna's 12-product portfolio, the competitive environment, as well as
the time and investments that would be required to conduct an additional Phase
III study in kidney cancer. These actions are part of the Company's strategy
aimed at reaching profitability for AEterna.

"This strategic decision will allow us to focus Neovastat efforts in lung cancer
only, even though, as reported by our committee of experts, our product has
shown potential for a sub-group of patients in our Phase III kidney cancer
trial," stated Mr. Gagnon.

Indeed, that trial did show an excellent safety profile and a more than 100%
increase in median survival time for a specific sub-group of healthier patients
(ECOG = 0) with a single metastatic site and clear-cell histology. Despite this
fact, another Phase III trial in kidney cancer would be required either with
patients having the same profile taking Neovastat in monotherapy or with another
group using Neovastat as first-line treatment in combination with standard
therapy. "Since this additional study would require major investments over a
four-year period, a time-frame that would not allow us to meet our main
investment criteria, we have decided not to pursue our activities in kidney
cancer. However, the ongoing Phase III trial in lung cancer with Neovastat does
meet our evaluation and clinical development criteria for an angiogenesis
inhibitor and justifies pursuing this trial," explained Gilles Gagnon. To this
effect, the Company announced the renewal of its agreement with the NCI for this
double-blind, placebo-controlled trial in which Neovastat is administered as
first-line treatment in combination with chemotherapy and radiotherapy. So far,
approximately 300 patients out of the 760 needed for this trial have been
enrolled.




While pursuing the lung cancer trial, the Company is also looking into other
business opportunities to enhance Neovastat's full commercial potential.

These strategic decisions call for a new organizational structure which will
allow optimal use of our different expertise and synergies between all AEterna
subsidiaries. This translates into the elimination of 63 jobs representing 20%
of the workforce at AEterna and its subsidiaries, which now stands at 240
employees in Canada, the United States, Germany and France.

These job-cuts will be made at all levels including four vice presidents: Vice
President, Legal Affairs and Corporate Secretary; Vice President Planning and
External Affairs; Vice President, Technical Operations; and Vice President
Clinical Affairs. Clinical activities will be assumed by the team supervised by
Prof. Dr. Jurgen Engel, PhD, current Executive Vice President, Global R&D and
Chief Operating Officer at AEterna. These measures will take effect as of today.
"I would like to thank all the employees and collaborators affected by these
measures for their hard work, devotion and loyalty during these past few years,"
stated Mr. Gagnon.

"Measures announced today, combined with our other corporate activities, are
part of our goals to be cash flow positive in 2004 and to tend towards
profitability, while maintaining R&D investments at a level of over $30 million
during 2004. I am convinced that these measures, along with our solid financial
position which includes $75 million in cash at September 30, 2003, will greatly
contribute in pursuing AEterna's growth strategy based on maximizing the value
of our 12-product portfolio and on acquisitions," concluded Mr. Gagnon.
