Devonian reports additional molecular data from MASH liver study

Gene expression analysis from the STAM mouse model attributes Thykamine™ with dose-dependent anti-MASH, anti-inflammatory and anti-fibrosis molecular effects in liver

QUÉBEC, Feb. 12, 2026 /CNW/ - Devonian Health Group Inc. ("Devonian" or the "Company") (TSXV: GSD) (OTCQB: DVHGF), a clinical stage corporation focused on developing unique solutions to fibroinflammatory diseases, today announced additional preclinical results from its previously reported STAM^TM mouse model in vivo study of metabolic dysfunction–associated steatohepatitis (MASH). These new data provide gene expression evidence supporting the anti-MASH, anti-inflammatory and anti-fibrotic effects of Thykamine™ observed in the liver.

As previously reported, the STAM™ mouse model study demonstrated that orally administered Thykamine™, at doses of 0.5 mg/kg, 5.0 mg/kg and 50.0 mg/kg once daily for three weeks, significantly reduced liver disease progression, inflammation and fibrosis. The gene expression results announced today further characterize the molecular mechanisms underlying these effects.

The study evaluated the impact of Thykamine™ on the expression of 29 genes associated with liver fibrosis and inflammation, including 13 fibrosis-related genes, 5 inflammation-related genes, and 11 genes involved in both inflammation and fibrosis pathways. At the maximum tested dose, Thykamine™ treatment resulted in marked down-regulation of multiple genes central to MASH pathophysiology, with several demonstrating reductions approaching or exceeding 80–90% relative to placebo-treated animals.

Fibrosis-related genes significantly modulated by Thykamine™ included CCN1, CCN2, COL1A1, COL1A2, COL5A2, JAG1, MMP2, MMP13, SERPINE1, SERPINE2, SNAI1, and TGFBR1, supporting the previously observed decreases in collagen deposition, α-SMA expression and fibrosis progression.

Thykamine™ treatment also resulted in significant down-regulation of inflammation-related genes, including CCL2, CCR2, IFNG, and MMO8, as well as genes involved in both inflammatory and fibrotic remodeling such as COL3A1, COL6A1, FN1, TGFB1, TIMP1, MMP14, TNF, IL10, and TLR4.

A dose-dependent response was observed across gene categories, consistent with a pharmacologically driven effect. In addition, gene expression analysis revealed key differences between the caudal and lateral liver lobes, indicating regional variation in Thykamine™'s molecular activity within the diseased liver.

Gene expression analysis (PCR) was performed by Dr. Louis Flamand, PhD, MBA, Department of Microbiology, Infectious Disease and Immunology, Faculty of Medicine, Université Laval, Quebec City, Quebec, Canada. Statistical analyses were conducted by Dr. John Sampalis, PhD, Department of Surgery, McGill University, Montreal, Quebec, Canada.

"We are delighted to share these gene expression results, which provide important molecular confirmation of the anti-inflammatory and anti-fibrotic effects of Thykamine™ observed in the STAM^TM MASH model," said Dr. Andre P. Boulet, PhD, Chief Executive Officer of the Company. "The data demonstrate that Thykamine™ modulates multiple genes involved in fibrosis and inflammation, reinforcing its potential to target underlying disease pathology and prevent progression of MASH."

"This study further adds to the growing body of evidence supporting Thykamine™'s multi-targeting mode of action," said Dr André P. Boulet PhD, CEO of the Company. "By demonstrating consistent effects at both the histological and molecular levels, these results strengthen Thykamine™'s positioning across a broad array of inflammatory diseases, now including hepatic conditions alongside dermatology and Inflammatory Bowel Dises."

The complete gene expression results will be included in the planned scientific publication of the STAM^TM MASH preclinical study.

About NAFLD/MASH^1,2

Nonalcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease with a worldwide prevalence of 20-30%.  It is represented by fat accumulation in the liver, a condition that is commonly associated with features of the metabolic syndrome (MetS), such as obesity, type 2 diabetes, dyslipidemia, and hypertension.

NAFLD progresses to metabolic dysfunction-associated steatohepatitis (MASH), the hallmarks of which are inflammation, hepatocellular ballooning, and subsequent worsening fibrosis. Left untreated, MASH can ultimately progress to cirrhosis of the liver and hepatocellular carcinoma, liver failure and death.

The global Metabolic Dysfunction-Associated Steatohepatitis (MASH) treatment market is experiencing rapid growth, driven by rising rates of obesity, type 2 diabetes, and metabolic syndrome³.  According to DataM Intelligence⁴, the market was valued at $7.87 billion in 2024 and is projected to reach $31.76 billion by 2033, growing at a 17.7% CAGR from 2025 to 2033. 

About Thykamine™

Thykamine™, the first pharmaceutical product issued from Devonian's SUPREX™ platform, is a highly innovative product for the prevention and treatment of health conditions related to fibroinflammation and oxidative stress including ulcerative colitis, atopic dermatitis, psoriasis, rheumatoid arthritis, and other autoimmune disorders. The anti-inflammatory, anti-oxidative and immunomodulatory properties of Thykamine™ have been demonstrated by a considerable number of in vitro and in vivo studies as well as in a Phase IIa clinical study in patients with mild-to-moderate distal ulcerative colitis and in a large Phase II study in adult patients with mild-to-moderate Atopic Dermatitis. Both Thykamine™ and SUPREX™ platform are covered by patents issued in several North American, European and Asian countries.

About Devonian

Devonian Health Group Inc. is a clinical stage pharmaceutical company specializing in the development of drugs for various auto-immune fibroinflammatory conditions with novel therapeutic approaches to targeting unmet medical needs.
