CHARLESTON, S.C.--(BUSINESS WIRE)--Aeterna Zentaris Inc. (NASDAQ: AEZS)(TSX: AEZS) (the “Company”) announced today that the Pediatric Committee (“PDCO”) of the European Medicines Agency (“EMA”) agreed to the Company’s Pediatric Investigation Plan (“PIP”) for Macrilen™ and agreed that the Company may defer conducting the PIP until after it files a Marketing Authorization Application (“MAA”) seeking marketing authorization for the use of Macrilen™ for the evaluation of adult growth hormone deficiency.

As part of the regulatory process for the registration of new medicines in Europe, pharmaceutical companies are required to provide a PIP outlining their strategy for investigation of the new medicinal product in the pediatric population. An accepted PIP is a prerequisite for filing an MAA for any new medicinal product in Europe. However, the Company will be able to file an MAA substantially earlier than if it was required to complete the PIP before filing, because the PDCO permitted the Company to defer conducting the studies defined in the PIP.

The Company’s PIP provides for a dose-escalation safety and PK/PD study followed by a diagnostic efficacy and safety study. The goal of the first study is to establish a dose that can safely be administered to pediatric patients and that causes a clear rise in growth hormone concentration in subjects ultimately diagnosed as not having growth hormone deficiency (“GHD”). The recommended dose derived from this study will be evaluated in the second study for diagnostic efficacy and safety. Both studies will be conducted in patients at least three years old who are undergoing the study sites’ regular diagnostic evaluation for the presence of GHD.

Dr. Richard Sachse, M.D., Ph.D., Senior Vice President, Chief Medical Officer and Chief Scientific Officer of the Company, said: “PDCO’s agreement that we may defer conducting our PIP, allowing us to go forward with an MAA in adults prior to initiating of the pediatric development program, is an important step forward in our efforts to bring Macrilen™ to market. Likewise, acceptance of our PIP is an important regulatory milestone for the product. At this time, we are looking forward to our upcoming FDA meeting, which has been scheduled for late March 2017, as a pre-requisite for a potential NDA submission based on our most recently announced completion of the pivotal Phase 3 study. Similarly, we are preparing for meetings with European agencies to discuss whether the conducted development program suffices for an MAA.”

About Macrilen TM (macimorelin)

Macimorelin, a ghrelin receptor 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 in the United States under the tradename Macrilen™.

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 as well as an increase of cardiovascular risks.
