Aeterna Zentaris Resubmits NDA for Macrilen™ for the Evaluation of Growth Hormone Deficiency in Adults

CHARLESTON, S.C.--()--Aeterna Zentaris Inc. (NASDAQ: AEZS) (TSX: AEZS) (the “Company”) today announced that it has resubmitted a new drug application (“NDA”) to the U.S. Food and Drug Administration (“FDA”), seeking approval of Macrilen™ (macimorelin) for the evaluation of growth hormone deficiency in adults (“AGHD”).

Commenting on the resubmission, Dr. Richard Sachse, the Company’s Chief Scientific Officer, stated, “I am pleased to announce that we re-submitted the NDA for Macrilen™ today. I would like to thank my team for their efforts in getting us to this point ahead of our previously announced schedule. We believe that the FDA review period of our NDA will be up to six months, setting the stage for potential approval of the product late in 2017 or early in 2018. If the product is approved, it will be the only FDA-approved drug for assessing AGHD.”

David A. Dodd, President and Chief Executive Officer of the Company stated, “We remain excited about the commercial prospects of Macrilen™. We believe it has the potential to rapidly become the new standard for assessing adult growth hormone deficiency, displacing the insulin tolerance test and capturing the majority of the market quickly following commercial launch. We anticipate successful FDA approval and, as a result, we continue to build our commercial organization and infrastructure in preparation for the earliest possible launch of Macrilen™. Our focus is to be prepared to launch the product in the first quarter of 2018.”

About MacrilenTM (macimorelin)

Macimorelin, a ghrelin agonist, is an orally-active small molecule that stimulates the secretion of growth hormone. Macimorelin has been granted orphan drug designation by the FDA for diagnosis of AGHD. The Company owns the worldwide rights to this patented compound and has significant patent protection left. The Company’s U.S. composition of matter patent expires in 2022 and its U.S. utility patent runs through 2027. The Company proposes, subject to FDA approval, to market macimorelin under the tradename Macrilen™.

About AGHD

AGHD affects approximately 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 body mass, exercise capacity, and overall quality of life as well as an increase of cardiovascular risks.
