AboutAeterna Zentaris Inc.

Aeterna Zentaris Inc. is a specialty biopharmaceutical company commercializing and developing therapeutics and diagnostic tests. The Company’s lead product, Macrilen™ (macimorelin), is the first and only U.S. FDA and European Commission approved oral test indicated for the diagnosis of adult growth hormone deficiency (AGHD). Macrilen™ is currently marketed in the United States through a license agreement with Novo Nordisk and Aeterna Zentaris receives double-digit royalties on sales. Aeterna Zentaris owns all rights to macimorelin outside of the U.S. and Canada.

Aeterna Zentaris is also leveraging the clinical success and compelling safety profile of macimorelin to develop it for the diagnosis of child-onset growth hormone deficiency (CGHD), an area of significant unmet need.

The Company is actively pursuing business development opportunities for the commercialization of macimorelin in Europe and the rest of the world, in addition to other non-strategic assets to monetize their value.
