CSCI COSCIENS Biopharma Inc

COSCIENS Biopharma Inc. (NASDAQ: CSCI) (TSX: CSCI) (“COSCIENS” or the “Company”), a specialty biopharmaceutical company developing and commercializing a diversified portfolio of cosmeceutical, nutraceutical and pharmaceutical products, today provided an update on the progress of its merger integration with Ceapro Inc. (“Ceapro”), including planned changes to its management team and advancements across its current business.

“With the initial integration efforts now well underway, I believe now is the ideal time for the next generation of leaders to make their mark on the future of COSCIENS. To that end, with my full support, our Board has engaged an executive recruiting firm to identify the next President and CEO of COSCIENS. I remain fully committed to lead and support COSCIENS while that search is underway and will provide whatever support my successor needs through the transition,” stated Gilles Gagnon, M.Sc., MBA, President and CEO of COSCIENS.”

Mr. Gagnon added, “The reason for creating COSCIENS and the stated goals of the Aeterna Zentaris (now COSCIENS) and Ceapro combination was, and remains:

• broadening the revenue base, product offering and pipeline;
• evaluating our combined product portfolio in an effort to create a mix of near-term revenue generating products with longer term, potentially higher reward products, while also diversifying our respective risks;
• right-sizing our administrative costs and prioritize capital with a clear focus on products and programs that have the best chance to succeed and create value inflection points; and
• taking steps to recruit future leadership talent and expertise to execute on our strategy and take COSCIENS to the next level.

The first two goals will take time to achieve – we want to ensure that we are looking at comprehensive data and market information when making key product related decisions. We also want to ensure that the next President and CEO will have a voice in key decisions as they chart the future direction of COSCIENS.”

Management has already initiated and is continuing towards further cost reduction measures, including efforts to right size the combined business through the elimination of a number of managerial and technical positions. As part of those efforts, COSCIENS is also reducing the spend on certain programs pending completion of data review.

The Company continues to review the results from the Phase 3 DETECT-Trial of macimorelin for the treatment of childhood growth hormone deficiency (“CGHD”) and, while that is occurring, is looking for opportunities to reduce its associated spend while still supporting macimorelin in its approved indication, adult human growth hormone deficiency. The Company has also made the decision to discontinue further spend on the preclinical research program to evaluate the potential use of macimorelin for the treatment of amyotrophic lateral sclerosis (“ALS”). The ALS program has taken far longer and will cost more than was first anticipated and the Company does not have sufficient confidence from the data obtained to date that it will ultimately provide the much needed treatment for ALS patients that it once hoped."

Development Projects Update

Pharmaceuticals:

Avenanthramides tablets – Anti-inflammatory product

• The Single Ascending Dose (“SAD”) arm of the Company’s Phase 1 safety and tolerability study has been completed with 48 healthy subjects with no significant clinical adverse events. The Montreal Heart Institute will now enroll 24 additional subjects, each of them receiving specific ascending doses. The Phase 1 study is expected to be completed by year-end.

Yeast beta glucan (“YBG”) – Anti-fibrotic product

• Pre-clinical studies successfully conducted over the last four years with researchers at McMaster University were published on September 9, 2024 in the prestigious publication, Biomaterials Scientific Journal. The data published demonstrated that PGX-processed yeast beta glucan (PGX-YBG) is respirable and able to safely and reliably reprogram cells (macrophages) responsible for the development of fibrotic disease like lung fibrosis in pre-clinical models.

AIM Biologicals – Parkinson’s Disease (“PD”)

• An abstract related to the Company’s AIM Biologicals PD development program was presented at the European Congress of Immunology held September 1-4, 2024, in Dublin by Dr. Jorg Wischhusen from Wurzburg University as part of the “INNOVATIVE TECHNOLOGIES AND IMMUNOTHERAPIES” track. The goal of this pre-clinical program is to demonstrate that the product confers neuroprotection in an animal model for Parkinson Disease.

Nutraceuticals:

Yeast beta glucan (YBG) – Immune booster

• Development of a YBG powder formulation for use as an immune booster has been completed.

Cosmeceuticals:

Avenanthramides (“AVA”) and Oat beta glucan – Wound healing

• Positive data from a pre-clinical study using AVA and OBG products were presented by Dr. Vince Li, Scientific Director of the Angiogenesis Foundation at the 2024 American Society for Nutrition Annual Meeting held in Chicago at the beginning of July 2024. The pre-clinical data demonstrated that both AVA and OBG accelerate the speed and quality of healing.

Technology Development:

Pressurized Gas eXpanded Technology (“PGX”):

• Edmonton Main Facility - PGX Scale-Up 50 Liters Vessel: Construction, installation and commissioning is completed. Validation trials using YBG were successfully performed to produce powder formulation. We plan to sell YBG produced from this facility as a nutraceutical in capsulation form.
• Austria Natex Facility - PGX Scale-Up 100 Liters Vessel: The project is on schedule.

About Pressurized Gas eXpanded Liquid Technology (PGX)

COSCIENS Biopharma’s patented Pressurized Gas eXpanded (PGX) Technology is a unique and disruptive technology with several key advantages over conventional drying and purification technologies that can be used to process biopolymers into high-value, fine-structured, open-porous polymer structures and novel biocomposites. PGX can make ultra-light, highly porous polymer structures on a continuous basis, which is not possible using today's conventional technologies. PGX Technology was invented by Dr. Feral Temelli from the Department of Agricultural, Food & Nutritional Science of the University of Alberta (U of A) along with Dr. Bernhard Seifried who worked on the PGX scale-up. The license from U of A provides COSCIENS Biopharma with exclusive worldwide rights in all industrial applications.
