Development Projects Update

Pharmaceuticals:

• Avenanthramides Tablets (Avs) in Development as an Anti-Inflammatory: The Phase 1-2a clinical trial being conducted at the Montreal Heart Institute has fully completed the Phase 1 part of the study with 72 subjects tested. No significant side effects have been observed from ascending doses ranging from 30 mg to 960 mg. The Company expects the Phase 2a efficacy study will be initiated in Q1 2025, with expected completion in Q3 2025.
  
  

Cosmeceuticals:

• Enriched Oat Flour with High Concentration of Avenanthramides: We have successfully produced and sold small batches for inclusion in cream formulations.
  
  
• JuventeDC Product Line: New website, juventedc.com, was launched on December 19, 2024.
  
  

Nutraceuticals:

• Yeast Beta Glucan (YBG) Powder - Immune Booster: Our YBG product has been successfully manufactured as part of our PGX scale up project in Edmonton, Alberta. Our YBG product is being finalized in capsule form with the goal to commercialize it as an immune booster in Q2 2025.
  
  
• Oat Beta Glucan (OBG) Chewable Bar – Cholesterol Reduction: We have successfully developed a unique, standardized formulation for a healthy confection which includes a high concentration of OBG with daily dosage according to approved claims in 10 developed countries. The substantive claims include reduction of LDL cholesterol, supporting cardiovascular health reduction of Type 2 diabetes risks, source of fiber for the maintenance of general good health and support of a healthy digestive system. COSCIENS' team anticipates the official commercial launch of its chewable bar OBG natural health product in Q1 2025, marking an important chapter in the Company's journey toward promoting wellness while expanding its business model.
  
  

Macimorelin:

• On August 27, 2024, the Company announced that the Phase 3 safety and efficacy study AEZS-130-P02 (the "DETECT-trial") evaluating macimorelin for the diagnosis of Childhood Onset Growth Hormone Deficiency ("CGHD") had failed to meet its primary endpoints according to the definitions in the study protocol. Based on the results of the study, we are prioritizing our pipeline moving forward and repositioning the Company as a pure play Life Science's business offering natural-based products. Therefore, while maintaining the current commercial indication for the use of macimorelin for the diagnosis of Adult Growth Hormone Deficiency ("AGHD"), the Company has decided to not make any future investments in macimorelin for the diagnosis of CGHD. Consequently, in order to further ensure the streamlining of operations and reduce costs, the roles of some additional members of management have been terminated, including Dr. Nicola Ammer, Chief Medical Officer, which will be ending on March 31, 2025.
  
  

"On behalf of the entire Board and Company, we are grateful to the members of the team for their years of dedicated service. Nicola has been a long-standing, valued member of our team and provided years of expertise for the development of macimorelin (Macrilen^®; Ghryvelin^®), the first and only U.S. FDA and European Medicines Agency approved oral test indicated for the diagnosis of adult growth hormone deficiency. We are thankful to each member of our team and sincerely thank them for the key roles they played," concluded Mr. Gagnon.

The Company plans to release a new corporate presentation outlining key development areas and upcoming milestones in January 2025.
