               AETERNA LABORATORIES REPORTS FIRST QUARTER RESULTs

QUEBEC CITY, QUEBEC, APRIL 18, 2001 - AEterna Laboratories Inc. (NASDAQ: AELA,
TSE: AEL) reported today its results for the three-month period ended March 31,
2001.

Sales for Atrium Biotechnologies Inc., a subsidiary of AEterna, were up by more
than 35% during this first quarter, reaching $2.8 million* compared to
$2 million for the same period last year. This gain is mainly due to increased
sales in the United States and in Asia as well as revenues generated by the
acquisition of a line of nutrition supplement products in the United States last
October.

AEterna's Research and Development expenses totaled $7.2 million in comparison
to $5.5 million during the same quarter of 2000. This increase results from
additional investments in the development of its lead product, Neovastat, for
current pivotal Phase III clinical trials in lung and kidney cancer and for the
current pivotal Phase II trial in multiple myeloma, a form of blood cancer.

During the first quarter, the Company registered a net loss of $3.6 million, or
$0.12 per share, compared to an adjusted net loss of $2.4 million (before gain
on dilution) or $0.08 per share for the quarter ended March 31, 2000. Major
investments in the ongoing late stage clinical program over the last twelve
months account for most of the net loss increase.

AEterna maintains a solid financial situation with more than $63.8 million in
cash and short-term investments as of March 31, 2001. The Company has access to
an additional $17 million through the Technology Partnerships Canada program and
has a $5 million sponsorship from the U.S. National Cancer Institute for its
pivotal Phase III clinical trial in non-small-cell lung cancer.

"Our sound financial management enables us to have access to sufficient funds to
complete our key clinical studies in kidney cancer and multiple myeloma," said
Dennis Turpin, Vice President and Chief Financial Officer at AEterna.

"This has been a landmark quarter in AEterna's ten year history at the
scientific, clinical and corporate levels," said Dr. Eric Dupont, President and
Chief Executive Officer at AEterna. "Phase I/II clinical results in renal cell
carcinoma showed a statistically significant two-fold increase in patient
survival time, while research data proving Neovastat's capacity to induce
apoptosis of endothelial cells, further emphasized its position as a unique
product with multiple mechanisms of action. Furthermore, by carefully following
our growth strategy, we successfully concluded our first two strategic alliances
with pharmaceutical companies for the European market. All these elements bring
us that much closer to our ultimate objective, which has always been and still
is, to be among



the first in this new therapeutic class of drugs in bringing an
angiogenesis inhibitor to market, " concluded Dr. Dupont.


OVERVIEW OF FIRST QUARTER ACTIVITIES:

CLINICAL RESULTS
     o        Clinical data from a Phase I/II clinical trial in patients with
              metastatic renal cell carcinoma (kidney cancer) refractory to
              standard treatments, showed a statistically significant two-fold
              increase (7.1 months to 16.3 months) in median survival time in
              patients who were administered a higher dose of Neovastat. These
              results were presented at the recent 92nd Annual Meeting of the
              American Association for Cancer Research (AACR).

SCIENTIFIC DATA
     o        Other new research results presented at the AACR meeting
              demonstrated a third mechanism of action of Neovastat which
              induces apoptosis (programmed cell death) of endothelial cells.
              These results confirmed Neovastat's position as a unique product
              with multiple mechanisms of action.

SCIENTIFIC PEER REVIEW
     o        An article by Doctors D.  Gingras,  N.  Mousseau,  A.  Renaud,
              E.  Beaulieu,  Z.  Kachra and R.  Beliveau pertaining to
              Neovastat's MMP inhibition activity, was published in Anti Cancer
              Research.

CORPORATE AFFAIRS
     o        AEterna signed its first two strategic alliances for the European
              market with Grupo Ferrer Internacional, S.A., from Spain, and
              Medac GmbH from Hamburg, the German oncology business unit of the
              multinational Schering AG.

INTELLECTUAL PROPERTY
     o        United States Patent and Trademark Office granted AEterna another
              key patent that covers a new process involved in the isolation of
              bioactive components from cartilage, thus broadening the
              protection and exclusivity of Neovastat. To this day, AEterna has
              filed 8 patents of which 5 have been granted.

CORPORATE AND SCIENTIFIC APPOINTMENTS
     o        In keeping with its  international  growth  strategy,  AEterna
              appointed  Ms. Stormy Byorum and Mr. Pierre MacDonald  to
              AEterna's  Board of  Directors,  while Mr.  Pierre  Laurin was
              named Board of  Directors President of its subsidiary,  Atrium
              Biotechnologies Inc. The Company also announced the appointment
              of Mr. Gilles Gagnon as AEterna's new Vice President and Chief
              Operating Officer.

     o        AEterna  appointed  oncologists,  Dr. Janice  Dutcher,  MD and
              Dr. Kenneth C.  Anderson,  MD, both from the United States, and
              Dr. Francois Berger, MD, PhD, from France, to its Scientific
              Advisory Board, reflecting the Company's clinical strategy to
              focus on oncology.
