Galectin Therapeutics Presented NAVIGATE Trial Results at the European Association for the Study of the Liver (EASL) 2025 Congress

• Data presentation included efficacy and biomarker analyses from the NAVIGATE trial (n=287).

• Belapectin 2 mg/kg demonstrated a statistically significant reduction in new varices at 18 months in the per-protocol population (p=0.04).
  

• Significantly fewer patients in the belapectin treatment arms experienced worsening of liver stiffness as measured by FibroScan®, reinforcing the potential beneficial effect of belapectin in halting the progression of MASH cirrhosis.
  

/EIN News/ -- NORCROSS, Ga., May 12, 2025 (GLOBE NEWSWIRE) -- Galectin Therapeutics Inc. (NASDAQ:GALT), the leading developer of galectin-3-targeted therapeutics for patients with MASH cirrhosis and portal hypertension, presented a late-breaking oral presentation of the NAVIGATE study analysis at the EASL 2025 Congress, on May 10, 2025, in Amsterdam, Netherlands. The NAVIGATE study evaluated belapectin, a galectin-3 inhibitor, in patients with MASH cirrhosis and portal hypertension.

The NAVIGATE trial (NCT04365868) is a global, multicenter, randomized, double-blind, placebo-controlled study. A total of 355 patients were randomized in a 1:1:1 ratio to receive intravenous belapectin at either 2 mg/kg of lean body mass (LBM) (n=119), 4 mg/kg LBM (n=118), or placebo (n=118) every other week for 18 months. The primary endpoint was the prevention of varices, assessed as a composite clinical outcome that included patients who developed any varices, experienced intercurrent events, or lacked an endoscopy or intercurrent events at 18 months.

The study evaluated both the intent-to-treat (ITT) population (N=355) and a pre-defined per-protocol population or completer population (PPP, N=287), the latter comprising patients who completed 18 months of treatment with upper endoscopies performed at both baseline and after 18 months of treatment. In the PPP population, the incidence of varices was 11.3% in the belapectin 2 mg/kg group and 13.5% in the 4 mg/kg group, compared to 22.3% in the placebo group. The 2 mg/kg dose demonstrated a 49.3% reduction in incidence of new varices compared to placebo (p=0.04), whereas the 4 mg/kg dose showed a 39.5% reduction in new varices compared to placebo (not statistically significant).

These clinical findings were further supported by non-invasive assessments. Specifically, liver stiffness, measured via FibroScan®, showed a notably lower proportion of patients with worsening in liver stiffness. Notably, the 2mg/kg group significantly outperformed placebo by 66% (p=0.02) and 51% (p=0.03) respectively in each category as shown below:

	placebo	2 mg/kg belapectin	4mg/kg belapectin
	N=88	N=94	N=87
>10 increase in kPa from baseline Percentage	11 12.5%	4 4.3%	9 10.3%
>30% increase from baseline Percentage	21 23.9%	11 11.7%	13 14.9%

As in prior trials, the safety profile of belapectin remains highly encouraging with incidence of adverse events and serious adverse events comparable across the three cohorts. Rates of discontinuation, adverse events (AEs), and serious adverse events (SAEs) were comparable to placebo, with no drug-related SAEs reported in the NAVIGATE trial.

Dr. Naim Alkhouri, MD, FAASLD, DABOM, Chief Academic Officer of Summit Clinical Research and the Director of the Steatotic Liver Program at the Clinical Research Institute of Ohio, commented: "We are excited to have presented results from the NAVIGATE study, which reinforces belapectin’s potential in addressing a significant unmet need in patients with MASH cirrhosis and clinically significant portal hypertension. Galectin Therapeutics was among the first to pursue prevention of esophageal varices as a clinical endpoint—an approach now gaining broader interest across the field. It’s encouraging to see the consistency in benefit with the 2 mg dose in this global study."

Dr. Naga Chalasani, David W. Crabb Professor of Gastroenterology and Hepatology and Adjunct Professor of Anatomy, Cell Biology & Physiology at Indiana University School of Medicine, stated: "The NAVIGATE study contributes meaningful new evidence supporting belapectin’s therapeutic potential in MASH cirrhosis. In addition to reducing varices development, the data show that fewer patients experienced worsening in liver stiffness measure by Fibroscan, a key biomarker of clinical outcomes. These liver stiffness thresholds are well established as being associated with poorer clinical outcomes, so this trend is particularly encouraging as the review of the full dataset continues. Belapectin clearly is showing benefit evidence across several clinically important endpoints and should be continued in clinical development as there is a significant unmet need for patients with MASH cirrhosis."

About Galectin Therapeutics
Galectin Therapeutics is dedicated to developing novel therapies to improve the lives of patients with chronic liver disease and cancer. Galectin’s lead drug belapectin is a carbohydrate-based drug that inhibits the galectin-3 protein, which is directly involved in multiple inflammatory, fibrotic, and malignant diseases, for which it has Fast Track designation by the U.S. Food and Drug Administration. The lead development program is in metabolic dysfunction-associated steatohepatitis (MASH, formerly known as nonalcoholic steatohepatitis, or NASH) with cirrhosis, the most advanced form of MASH-related fibrosis. Liver cirrhosis is one of the most pressing medical need and a significant drug development opportunity. Additional development programs are in treatment of combination immunotherapy for advanced head and neck cancers and other malignancies. Advancement of these additional clinical programs is largely dependent on finding a suitable partner. Galectin seeks to leverage extensive scientific and development expertise as well as established relationships with external sources to achieve cost-effective and efficient development.
