Galectin Therapeutics Reports March 31, 2026 Financial Results and Provides Business Update

NORCROSS, Ga., May 15, 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 three months ended March 31, 2026.

“We continue to make meaningful progress advancing the belapectin program and further analyzing the NAVIGATE dataset in patients with MASH cirrhosis and portal hypertension. The additional analyses, including biomarker data, continue to support the potential of belapectin to impact disease progression in this high-risk population. We are looking forward to our upcoming data presentations at EASL later this month and our in-person Type-C meeting with FDA this quarter. Additionally, we remain focused on engaging with potential partners and leading experts to help determine the optimal path forward. This is an extremely exciting and consequential time in the Company’s history, and we will share updates as soon as possible.” said Joel Lewis, Chief Executive Officer and President of Galectin Therapeutics.

Belapectin Program HighlightsBelapectin is a complex carbohydrate drug that targets galectin-3, a critical protein in the pathogenesis of MASH and fibrosis.

MASH Cirrhosis

• NAVIGATEPhase 2b/3 trial (NCT04365868) is a global, randomized, double-blind, placebo-controlled study evaluating the efficacy and safety of belapectin intravenously either belapectin 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 for the prevention of esophageal varices in MASH cirrhosis.

• Additional analyses from the NAVIGATE trial, including biomarker data, continue to support the potential of belapectin to impact disease progression in this high-risk population.Statistically significant reductions in liver stiffness measurements (LSM), assessed by FibroScan®, were observed in the belapectin 2 mg/kg treatment arm at Weeks 26, 52 and 78, based on Mixed Model for Repeated Measures (MMRM) analyses of all clean and verified data collected throughout the study.Treatment with belapectin was associated with a reduction in the proportion of patients experiencing clinically meaningful worsening in liver stiffness compared to placebo, including fewer patients with >30% increases from baseline (11.7% vs. 23.9%; p=0.03) and fewer patients with combined increases of >10 kPa and >30% over the 18-month treatment period.These thresholds are clinically meaningful and associated with increased risk of liver-related complications, and the findings are consistent with a reduction in fibrosis progression, with placebo-treated patients continuing to demonstrate expected disease worsening over time.

• These thresholds are clinically meaningful and associated with increased risk of liver-related complications, and the findings are consistent with a reduction in fibrosis progression, with placebo-treated patients continuing to demonstrate expected disease worsening over time.

• Announced the appointment of Dr. Henry Brem to its Board of Directors in January 2026, further strengthening governance and strategic oversight.

• Hosted a virtual key opinion leader (KOL) event in March 2026 focused on MASH cirrhosis and the clinical development of belapectin.

• Additional biomarker analyses from the NAVIGATE trial, including evaluation of belapectin’s impact on liver stiffness and fibrogenesis, will be presented in oral and poster presentations at the European Association for the Study of the Liver Congress in Barcelona, Spain:Oral presentation by Mazen Noureddin: “Belapectin reduces varices development in high-risk MASH cirrhosis by modulating fibrogenesis balance as reflected by Pro-C3/CTX-III ratio” (Abstract REG26-611; Saturday, May 30, 2026, 10:15 AM–11:30 AM CET).Poster presentation by Naim Alkhouri: “Risk reduction in clinically significant portal hypertension with belapectin in advanced MASH cirrhosis: results from the NAVIGATE trial” (Abstract REG26-612; Thursday, May 28, 2026, 8:30 AM–5:00 PM CET).

• Upcoming FDA meeting to align on next steps for advancing the belapectin program and informing future clinical development plans in 2Q 2026.

• Oral presentation by Mazen Noureddin: “Belapectin reduces varices development in high-risk MASH cirrhosis by modulating fibrogenesis balance as reflected by Pro-C3/CTX-III ratio” (Abstract REG26-611; Saturday, May 30, 2026, 10:15 AM–11:30 AM CET).

• As of March 31, 2026, the Company had $14.1 million of cash and cash equivalents. Additionally, the Company has $10 million remaining available under a line of credit provided by its chairman of the board to fund operations. The Company believes it has sufficient cash to fund currently planned operations and research and development activities through May 2027.

• Research and development expenses for the quarter ended March 31, 2026 were $2.2 million compared with $6.5 million for the same period in 2025. The decrease was primarily due to timing of incurrence of expenditures related to our NAVIGATE clinical trial.

• General and administrative expenses for the quarter ended March 31, 2026 were $1.8 million, compared to $1.4 million for the quarter ended March 31, 2025. The increase was primarily due to an increase in non-cash, stock-based compensation expense.

• For the quarter ended quarter ended March 31, 2026, the Company reported a net loss applicable to common stockholders of $5.1 million, or ($0.08) per share, compared to a net loss applicable to common stockholders of $9.6 million, or ($0.15) per share for the quarter ended March 31, 2025.

• These results are included in the Company's Quarterly Report on Form 10-Q as of and for the period ended March 31, 2026, which has been filed with the U.S. Securities and Exchange Commission and is available atwww.sec.gov.

About Galectin TherapeuticsGalectin 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.
