Aeterna Zentaris Inc. is a specialty biopharmaceutical company headquartered in Laval, Quebec, with a strategic focus on developing treatments in the fields of oncology and endocrinology. The company advances both proprietary and partnered programs, leveraging peptide- and small-molecule–based technologies to address unmet medical needs. Through its targeted approach, Aeterna Zentaris aims to bring novel diagnostics and therapies to market, often in collaboration with global pharmaceutical partners.
The company’s lead commercial product is macimorelin, an orally administered diagnostic agent for adult growth hormone deficiency.

These pipeline assets are undergoing various stages of preclinical and clinical development aimed at prostate, endometrial and other receptor-positive malignancies.
In addition to its proprietary research, Aeterna Zentaris has forged partnerships to expand the commercial reach of its assets and to co-develop new candidates. The company conducts its research and early-stage development in Canada while engaging clinical trial sites across North America and Europe. This geographic footprint enables Aeterna Zentaris to access diverse patient populations and to optimize regulatory strategies in multiple jurisdictions.
Aeterna Zentaris is led by an executive team with extensive experience in biopharmaceutical R&D, regulatory affairs and commercial operations. Supported by a board of directors featuring industry veterans, the company pursues a disciplined development strategy, balancing near-term commercial opportunities with longer-term innovation. By combining diagnostic platforms with targeted therapeutics, Aeterna Zentaris seeks to carve out a niche in specialty care areas where precision and patient convenience are paramount.
