QUEBEC CITY, Canada I November 19, 2015 I Aeterna Zentaris Inc. (NASDAQ:  AEZS)(TSX: AEZ) (the “Company”) announced today that the first patient has been enrolled for the Company’s confirmatory Phase 3 clinical study to demonstrate the efficacy of Macrilen™ (macimorelin), a novel orally-active ghrelin agonist for use in evaluating adult growth hormone deficiency (“AGHD”).

David A. Dodd, Chairman, President and Chief Executive Officer of the Company, remarked, “We remain committed to the development of Macrilen™ because of our confidence in its efficacy and safety, as well as the medical need for such a convenient test in the absence of an FDA-approved diagnostic test for AGHD.” 

About the Study

The confirmatory Phase 3 clinical study of Macrilen™, entitled Confirmatory validation of oral macimorelin as a growth hormone (GH) stimulation test (ST) for the diagnosis of adult growth hormone deficiency (AGHD) in comparison with the insulin tolerance test (ITT), is designed as a two-way crossover study with the insulin tolerance test as the benchmark comparator and will involve some 30 sites in the United States and Europe.  The study population will consist of approximately 110 subjects (at least 55 ITT-positive and 55 ITT-negative) with a medical history documenting risk factors for AGHD, and will include a spectrum of subjects from those with a low risk of having AGHD to those with a high risk of having the condition.  The primary endpoint is validation of a single oral dose of macimorelin for the diagnosis of AGHD, using the ITT as a comparator.  The coordinating investigator is Jose Manuel Garcia, MD, PhD, Associate Professor of Medicine-Endocrinology at Baylor College of Medicine in Houston, Texas. 

Based on meetings with the US Food and Drug Administration (“FDA”) as well as the European Medicines Agency (“EMA”) and subsequent written scientific advice, the Company believes that the study meets the FDA’s and the EMA’s study-design expectations allowing US and European approval, if successful.

About MacrilenTM (macimorelin)

Macimorelin, a ghrelin agonist, is a novel orally-active small molecule that stimulates the secretion of growth hormone.  Macimorelin, under the trade name MacrilenTM, has been granted orphan drug designation by the FDA for diagnosis of AGHD.  The Company owns the worldwide rights to this novel patented compound.

About AGHD

AGHD affects approximately 75,000 adults across the US, 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 body mass, exercise capacity, and overall quality of life.
