About Aeterna Zentaris

Aeterna Zentaris is a specialty biopharmaceutical company engaged in developing and commercializing novel pharmaceutical therapies.  We are engaged in drug development activities and in the promotion of products for others.  We recently completed Phase 3 studies of two internally developed compounds.  The focus of our business development efforts is the acquisition of licenses to products that are relevant to our therapeutic areas of focus.  We also intend to license out certain commercial rights of internally developed products to licensees in non-U.S. territories where such out-licensing would enable us to ensure development, registration and launch of our product candidates.  Our goal is to become a growth-oriented specialty biopharmaceutical company by pursuing successful development and commercialization of our product portfolio, achieving successful commercial presence and growth, while consistently delivering value to our shareholders, employees and the medical providers and patients who will benefit from our products.  In addition, the Company currently co-promotes two products: Saizen® [somatropin (rDNA origin) for injection], a recombinant human growth hormone supplement, on behalf of EMD Serono; and, APIFINY®, the first non-PSA blood test for use in evaluating and managing the risk of prostate cancer, on behalf of Armune Bioscience.
