Aeterna Zentaris Submits New Drug Application to FDA for Macimorelin Acetate (AEZS-130) for Evaluation of AGHD

November 5, 2013

QUEBEC, Nov. 5, 2013 /PRNewswire/ – Aeterna Zentaris Inc. (NASDAQ: AEZS)
(TSX: AEZS) (the “Company”) today announced that it has submitted a New
Drug Application (“NDA”) to the U.S. Food and Drug Administration
(“FDA”) for its ghrelin agonist, macimorelin acetate (AEZS-130). Phase
3 data have demonstrated that the compound has the potential to become
the first orally-approved product that induces growth hormone release
to evaluate adult growth hormone deficiency (“AGHD”), with accuracy
comparable to available intravenous and intramuscular testing

David Dodd, President and CEO of Aeterna Zentaris, commented, “The
submission of the NDA to the FDA is another major milestone in our
strategy to bring macimorelin acetate to market as the first approved
oral product for AGHD evaluation. We are also looking at potential
expansion into traumatic brain injury victims and pediatrics which
would represent significant growth opportunities for the Company.
Finally, I would like to congratulate and thank all those involved in
our drug development and regulatory affairs departments for this
exciting accomplishment.”

About Macimorelin Acetate (AEZS-130)

Macimorelin acetate, a ghrelin agonist, is a novel orally-active small
molecule that stimulates the secretion of growth hormone. The Company
has completed a Phase 3 trial for use in evaluating AGHD, and has
submitted a NDA to the FDA in this indication. Macimorelin acetate has
been granted orphan drug designation by the FDA for use in AGHD.
Furthermore, macimorelin acetate is in a Phase 2 trial as a treatment
for cancer-induced cachexia. Aeterna Zentaris owns the worldwide rights
to this novel patented compound.

About AGHD

AGHD affects about 75,000 adults across the U.S., Canada and Europe.
Growth hormone not only plays an important role in growth from
childhood to adulthood, but also helps promote a hormonally-balanced
health status. AGHD mostly results from damage to the pituitary gland.
It is usually characterized by a reduction in bone mineral density,
lean mass, exercise capacity, and overall quality of life.
