NORCROSS, Ga., May 11, 2026 (GLOBE NEWSWIRE) -- Galectin Therapeutics Inc. (NASDAQ:GALT), a clinical-stage biotechnology company developing therapeutics that target galectin-3 for patients with MASH cirrhosis and portal hypertension, today announced the publication of results from its NAVIGATE Phase 2b clinical trial evaluating belapectin in patients with MASH cirrhosis and portal hypertension in AASLD flagship journal Hepatology. The manuscript, titled “Efficacy and Safety of Belapectin for the Prevention of Esophageal Varices in Patients with MASH Cirrhosis: The Randomized, Placebo-Controlled NAVIGATE Trial,” is now available online and available as an open-access publication. The NAVIGATE trial evaluated belapectin, a galectin-3 inhibitor, in patients with MASH cirrhosis and portal hypertension without esophageal varices at baseline. Results demonstrated that belapectin 2 mg/kg was associated with a numerical reduction in the development of new varices compared to placebo in the full analysis set, with a statistically significant reduction observed in the per-protocol population. Key markers of fibrosis including Liver Stiffness Measure results were aligned with the clinical finding belapectinwas generally safe and well tolerated. “These findings provide clinically meaningful evidence for the potential role of belapectin in addressing portal hypertension and reducing the risk of clinically significant complications in patients with MASH cirrhosis,” said Prof. Naga Chalasani, David W. Crabb Professor of Gastroenterology and Hepatology at Indiana University School of Medicine and principal investigator for the NAVIGATE program. “The observed reduction in variceal development, together with consistent biomarker findings and a favorable safety profile, supports continued development of belapectin in patients with MASH cirrhosis and portal hypertension—a population with substantial unmet medical need.” “These results further strengthen the clinical and mechanistic pro belapectin in MASH cirrhosis and portal hypertension,” said Khurram Jamil, M.D., Chief Medical Officer of Galectin Therapeutics. “The consistency across clinical outcomes and noninvasive biomarkers, including signals of reduced risk of clinically significant portal hypertension and variceal development, reinforces our confidence in belapectin’s potential to modify disease progression. We believe these data meaningfully support continued advancement of our program, while positioning belapectin as a differentiated therapeutic candidate in MASH cirrhosis with portal hypertension—a market with significant unmet need and limited treatment options.” The manuscript highlights: Numerical reduction in incidence of new esophageal varices with belapectin 2 mg/kg compared to placebo Statistically significant reduction in the per-protocol population Supportive changes in non-invasive markers of portal hypertension and fibrosis including LSM and ELF. Favorable safety and tolerability profile Belapectin targets galectin-3, a key mediator of fibrosis and inflammation, and is being developed as a potential therapy to address complications of MASH cirrhosis. The full manuscript is available online and can be accessed here freely given its open-access status.

NORCROSS, Ga., March 31, 2026 (GLOBE NEWSWIRE) -- Galectin Therapeutics, Inc. (NASDAQ: GALT), the leading developer of therapeutics that target galectin proteins, today reported financial results and provided a business update for the year ended December 31, 2025. Joel Lewis, Chief Executive Officer and President of Galectin Therapeutics, said “We are at an important juncture for the belapectin development program. During 2025, we made meaningful progress advancing the belapectin program and continuing our analysis of the NAVIGATE dataset in patients with MASH cirrhosis and portal hypertension. We are encouraged by the signals observed, including additional biomarkers from the NAVIGATE dataset, and remain focused on evaluating the data as we engage with regulators, potential partners, and leading experts to determine the optimal path forward for the program. Importantly, we also improved the Company’s financial position during the year, including securing an additional $10 million line of credit from our Chairman, Dick Uihlein, to extend our projected cash runway through April 2027. Also, just very recently, we have strengthened our Board with the appointment of Dr. Henry Brem, an internationally recognized neurosurgeon-scientist and leader in translational medicine, whose clinical development experience will be valuable as we advance the program. With no approved therapies currently available for patients with MASH cirrhosis, we believe belapectin has the potential to address a significant unmet medical need and look forward to discussing the program with FDA.” Khurram Jamil, M.D., Chief Medical Officer, added “The NAVIGATE dataset continues to provide encouraging insights supporting belapectin’s potential role in patients with MASH cirrhosis and portal hypertension. In addition to the previously reported clinical finding of reduced varices incidence in the per-protocol population, additional biomarker analyses have demonstrated consistent signals across specialized markers of fibrosis and noninvasive measures of liver stiffness, supporting belapectin’s potential antifibrotic activity and disease-modifying effect. These findings have been well received by the scientific community and were recently discussed by leading hepatology experts during our March 10, 2026 virtual KOL event, where the data were reviewed in the context of disease progression and portal hypertension category risk in MASH cirrhosis. Taken together, these results further strengthen the biological rationale for galectin-3 inhibition and support continued evaluation of belapectin as a potential therapy for patients with MASH cirrhosis, a population for whom there are currently no approved treatment options. We are excited about our upcoming FDA meeting in the second quarter of 2026 to align on the next steps for advancing the program. We are pleased to announce that multiple abstracts from the NAVIGATE program have been accepted for presentations at the upcoming EASL Congress, including one oral presentation. This builds on our momentum from last year’s late-breaker presentation at EASL and oral presentation at AASLD 2025 and reflects the continued interest from the scientific community in our unique and comprehensive dataset.” Belapectin Program Highlights Belapectin is a complex carbohydrate drug that targets galectin-3, a critical protein involved in fibrosis and inflammation associated with MASH and portal hypertension. MASH Cirrhosis NAVIGATE Phase 2b/3 trial ( NCT04365868 ) is a global, randomized, double-blind, placebo-controlled study evaluating belapectin administered intravenously at 2 mg/kg or 4 mg/kg of lean body mass (LBM) versus placebo every two weeks for 18 months for the prevention of esophageal varices in patients with MASH cirrhosis. The NAVIGATE trial demonstrated: In the intent-to-treat population (n=355), the incidence of varices at 18 months was 43.2% lower in patients treated with belapectin 2 mg/kg compared with placebo, although the composite endpoint did not reach statistical significance. In the per-protocol population (n=287), belapectin 2 mg/kg reduced the incidence of varices by 49.3% versus placebo (nominal p = 0.04). In U.S. patients within the per-protocol population (n=186), belapectin 2 mg/kg reduced the incidence of varices by 68.1% compared with placebo (p = 0.02). Safety results showed a similar proportion of treatment-emergent adverse events, serious adverse events, and discontinuations across treatment groups, with no drug-related serious adverse events observed. Additional 18-month NAVIGATE biomarker analyses presented in 2025 demonstrated consistent effects across multiple non-invasive markers of fibrosis and disease progression, including FibroScan® liver stiffness measurement, ELF score, and PRO-C3, further supporting belapectin’s potential antifibrotic and disease-modifying activity in patients with compensated MASH cirrhosis and portal hypertension. Additional mechanistic analyses, including YKL-40 and PRO-C4, further supported belapectin’s biological activity, with findings consistent with reduced inflammation and fibrogenesis. Analyses using validated Baveno VII criteria suggested belapectin treatment was associated with improvements in portal hypertension risk categories and a reduced risk of hepatic decompensation compared with placebo. In March 2026, the Company hosted a virtual KOL event featuring leading hepatology experts who reviewed additional NAVIGATE biomarker findings and discussed their implications for disease progression and portal hypertension risk in MASH cirrhosis. The Company will present new NAVIGATE trial analyses at EASL 2026 (May 27–30, 2026), including an oral presentation on reduced varices based on favorable changes in markers of fibrosis formation and resolution (PRO-C3/CTX-III), and a poster presentation on risk reduction in clinically significant portal hypertension in advanced MASH cirrhosis. Full Year 2025 Financial Highlights As of December 31, 2025, the Company had $17.7 million of unrestricted cash and cash equivalents in addition to $10 million available under a line of credit provided by our chairman to fund future operations. The Company believes it has sufficient cash to fund currently planned operations and research and development activities through April 2027. Research and development expenses for the year ended December 31, 2025 were $14.3 million compared with $36.6 million for the year ended December 31, 2024. The decrease was primarily due to costs related to our NAVIGATE clinical trial and other supportive activities. General and administrative expenses for the year ended December 31, 2025 were $5.8 million, compared to $5.9 million for the year ended December 31, 2024. For the year ended December 31, 2025, the Company reported a net loss applicable to common stockholders of $31.0 million, or ($0.48) per share, compared to a net loss applicable to common stockholders of $47.2 million, or ($0.76) per share, for the year ended December 31, 2024. The decrease is largely due to a decrease in research and development costs due to the conclusion of the NAVIGATE trial.
