Galectin Therapeutics Reports Financial Results for the Quarter Ended

Galectin Therapeutics Reports Financial Results for the Quarter Ended March 31, 2023 and Provides Business Update

NORCROSS, Georgia, May 15, 2023 (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, 2023. These results are included in

the Company's Quarterly Report on Form 10-Q, which has been filed with the U.S. Securities and Exchange Commission and is available at www.sec.gov.

Joel Lewis, Chief Executive Officer and President of Galectin Therapeutics, said:

"Our entire team is actively engaged in oversight and management of our adaptively designed Phase 2b/3 NAVIGATE trial for the prevention of

esophageal varices in patients with NASH cirrhosis, which completed randomization of 357 patients in February 2023. Our stated target remains obtaining interim analysis results from the Phase 2b portion in the fourth quarter of 2024. The Company's

results will be the first, and as of now, the only late-stage trial in compensated cirrhosis that has advanced to include portal hypertension caused by NASH. Currently, this patient population has no therapeutic option, other than liver

Additionally, we are continuing to evaluate options and develop plans for a potential Phase 2 clinical trial of belapectin in combination

with Keytruda in patients with advanced head and neck cancers. Our team is fully committed to maximizing the value of our company for the stockholders by advancing our programs for patients."

Dr. Pol Boudes, Chief Medical Officer stated: "Joel and I were pleased to

discuss our innovative NAVIGATE trial for the prevention of esophageal varices with Ed Arce, managing director of equity research at H.C. Wainwright on May 2, 2023. A replay of that discussion is available in the Investor Relations section of

our website, www.galectintherapeutics.com. As we

reiterated in that discussion, as compared to NASH pre-cirrhotic stages, cirrhosis of the liver is characterized by a distinct pathophysiology, with activated macrophages, the target of belapectin, playing a central role in the progression to

portal hypertension and, ultimately, liver failure. We continue to be encouraged by the apparent high level of safety and tolerance of belapectin in the NAVIGATE patient population, and we remain optimistic that the NAVIGATE results can one day

bring a therapy to patients with NASH cirrhosis that currently can only contemplate liver transplantation as a therapeutic option."

For the three months ended March 31, 2023, the Company reported a net loss applicable to common stockholders of $11.5 million, or ($0.19) per share, compared to

a net loss applicable to common stockholders of $9.9 million, or ($0.17) per share for the three months ended March 31, 2022. The increase is largely due to an increase in 2023 research and development expenses related to the Company's NAVIGATE

Research and development expenses for the three months ended March 31, 2023, was $8.8 million compared with $8.1 million for the three months ended March 31,

2022. The increase was primarily due to costs related to our NAVIGATE clinical trial and other supportive activities. General and administrative expenses for the three months ended March 31, 2023, were $1.5 million, compared to $1.9 million for the

three months ended March 31, 2022. The decrease was primarily due to non-cash stock-based compensation expense.

As of March 31, 2023, the Company had $17.8 million of cash and cash equivalents. Additionally, the Company has $40 million remaining available under a $60

million line of credit provided by its chairman to fund operations. The Company believes it has sufficient cash to fund currently planned operations and research and development activities through at least December 31, 2024.

The Company expects that it will require more cash to fund operations after December 31, 2024, and believes it will be able to obtain additional financing as

needed. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be on terms favorable to us.

Belapectin is a complex carbohydrate drug that targets galectin-3, a critical protein in the pathogenesis of NASH and fibrosis. Galectin-3 plays a major role in

diseases that involve scarring of organs, including fibrotic disorders of the liver, lung, kidney, heart, and vascular system. Belapectin binds to galectin-3 and disrupts its function. Preclinical data in animals have shown that belapectin has

robust treatment effects in reversing liver fibrosis and cirrhosis. A Phase 2 study showed belapectin may prevent the development of esophageal varices in NASH cirrhosis, and these results provide the basis for the conduct of the NAVIGATE trial.

The NAVIGATE trial (www.NAVIGATEnash.com), titled "A Seamless Adaptive Phase 2b/3, Double-Blind, Randomized, Placebo-controlled Multicenter, International Study Evaluating the Efficacy and Safety of Belapectin (GR-MD-02) for the Prevention of

Esophageal Varices in NASH Cirrhosis," completed randomization of 357 patients in February 2023 with top-line data expected from the Phase 2b portion in the fourth quarter of 2024, and is posted on www.clinicaltrials.gov (NCT04365868). Galectin-3

has a significant role in cancer, and the Company has supported a Phase 1b study in combined immunotherapy of belapectin and Keytruda in advanced melanoma and in head and neck cancer. This trial provided a strong rationale for moving forward into a

Company-sponsored Phase 2 development program, which the company is exploring.

About Fatty Liver Disease with Advanced Fibrosis and Cirrhosis

Non-alcoholic steatohepatitis (NASH), also known as fatty liver disease, has become a common disease of the liver with the rise in obesity and other metabolic

diseases. NASH is estimated to affect up to 28 million people in the U.S. It is characterized by the presence of excess fat in the liver along with inflammation and hepatocyte damage (ballooning) in people who consume little or no alcohol. Over

time, patients with NASH can develop excessive fibrosis, or scarring of the liver, and ultimately liver cirrhosis. It is estimated that as many as 1 to 2 million individuals in the U.S. will develop cirrhosis as a result of NASH, for which liver

transplantation is the only curative treatment available. Approximately 9,000 liver transplants are performed annually in the U.S. There are no drug therapies approved for the treatment of liver fibrosis or 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 (formerly known as GR-MD-02) 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 non-alcoholic steatohepatitis (NASH) with cirrhosis, the most advanced form of NASH-related fibrosis. This is the most common liver disease and one of the largest drug development

opportunities available today. Additional development programs are in treatment of combination immunotherapy for advanced melanoma 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. Additional information is available at www.galectintherapeutics.com.
