TORONTO, ONTARIO, May 13, 2025 (GLOBE NEWSWIRE) -- COSCIENS Biopharma Inc. (NASDAQ: CSCI) (TSX: CSCI) (“COSCIENS” or the “Company”), a life sciences company which develops and commercializes a diversified portfolio of cosmeceutical, nutraceutical and pharmaceutical products, today reported its financial and operating results for the first quarter ended March 31, 2025 and provided a corporate update.

Development Projects Update

Pharmaceuticals:

• Avenanthramides Tablets in Clinical Development as an Anti-Inflammatory Product:
  • During the first quarter of 2025, the Company announced successful Phase 1 results from the Phase 1 clinical study of its Avenanthramides tablets. That study involved 72 healthy subjects. There were no significant clinical adverse events observed from ascending doses ranging from 30 mg to 960 mg of the Company’s Avenanthramides tablets in that Phase 1 clinical study.
  • As a result of the successful completion of that Phase 1 clinical study, the Company launched a Phase 2a clinical efficacy study of its Avenanthramides tablets on March 15, 2025. That study includes 20 patients divided in two cohorts. The first cohort of 10 patients who received a daily dose of 480 mg is completed. Subsequent to the end of the first quarter, data from those 10 patients was reviewed by independent members of the Data and Safety Monitoring Board (DSMB). The DSMB recommended that the study continue as planned with a second cohort of 10 patients who will receive a daily dose of 960 mg. The Company’s goal remains to complete the Phase 2a Clinical Efficacy Study during Q3, 2025.

Nutraceuticals:

• The COSCIENS team is working to commercialize a new portfolio of nutraceuticals leveraging the deep understanding and expertise in the active ingredients category and marking an important chapter in the Company's journey toward promoting wellness while expanding its business model. Those include:
  • 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 OBG product monograph in 10 developed countries.
  • 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.

Technology:

• Pressurized Gas eXpanded Technology (PGX Technology):
  • Edmonton Main Facility PGX Scale Up 50 Liters Vessel: The project is completed and the equipment is ready to produce YBG at a small-scale commercial level.

Summary of First Quarter 2025 Financial Results

All amounts are in U.S. dollars.

Cash and cash equivalents

The Company had $13.8 million in cash and cash equivalents at March 31, 2025.

Results of operations for the three-month period ended March 31, 2025

For the three-month period ended March 31, 2025, we reported a consolidated net loss of $3.7 million, or $1.16 loss per common share, as compared with a consolidated net loss of $1.4 million, or $0.76 loss per common share for the same period in 2024. The $2.3 million increase in net loss is primarily due to increases in operating expenses of $1.4 million, a $0.5 million decrease in gross margin, and a decrease of $0.4 million in income tax recoveries.

Revenues

• Our total revenue for the three-month period ended March 31, 2025, was $1.5 million as compared to $2.1 million for the same period in 2024, a decrease of $0.6 million. This decrease was primarily due to a $0.7 million decrease in sales of Avenanthramides, Beta Glucan, and Oat Oil from prior period, offset by $0.1 million in Macrilen revenue.

Operating Expenses

• Our total operating expenses for the three-month period ended March 31, 2025, were $4.0 million as compared with $2.7 million for the same period in 2024. This increase of $1.3 million was due to higher selling, general and administrative costs of $1.2 million due primarily to the merger completed in June 2024 between Aeterna (now COSCIENS) and Ceapro, as well as a slight increase in research and development costs of $0.1 million related mainly to timing and residual expenses associated with certain post-trial activities related to the DETECT trial.
• Since the merger, we have successfully reduced overall spend by leveraging restructuring initiatives and operational synergies. This is reflected in our quarter-over-quarter reduction in cash spend, decreasing from $3.6M in Q4 2024 to $2.6M in Q1 2025.
