PRESS RELEASE

Dec. 19, 2013, 8:01 a.m. EST

NORCROSS, Ga., Dec 19, 2013 (GLOBE NEWSWIRE via COMTEX) -- Galectin Therapeutics Inc. GALT +4.65% , the leading developer of therapeutics that target galectin proteins to treat fibrosis and cancer, today announced that new preclinical data show its leading galectin-inhibiting drugs - GR-MD-02 and GM-CT-01 - demonstrate positive therapeutic effects on nonalcoholic steatohepatitis (NASH, or fatty liver disease) with fibrosis. Results were published in an article titled "Therapy of Experimental NASH and Fibrosis with Galectin Inhibitors" in the peer-reviewed, open-access journal PLOS ONE.

In the study, NASH-induced mice were treated with GM-CT-01 and GR-MD-02 at two different points - early fibrosis and later more severe fibrosis. The studies evaluated twice-weekly, dose escalation of once weekly by intravenous administration, as well as evaluated different routes of administration including intravenous, subcutaneous and oral.

Results revealed that treatment with GR-MD-02 significantly improved NASH activity and reduced fibrosis including prevention of accumulation of collagen and/or reduced accumulated collagen in the liver. Similar effects were seen with GM-CT-01 but with approximately four-fold lower potency than GR-MD-02. The data also show reduction in galectin-3 expression and other inflammatory biomarkers. The PLOS ONE article can be found online at http://dx.plos.org/10.1371/journal.pone.0083481

"There are currently no approved treatments for fatty liver disease with fibrosis, a major health problem in the United States. These preclinical findings add to our scientific understanding of the role galectin inhibitors play in the treatment of fatty liver disease," said Peter G. Traber, M.D., Chief Executive Officer, President and Chief Medical Officer, Galectin Therapeutics. "The results support our current Phase 1 clinical trial of GR-MD-02 and our long-term development programs for GM-CT-01 and GR-MD-02."

GM-CT-01 and GR-MD-02 are proprietary molecules that bind to and inhibit galectin proteins, predominantly galectin-3. Six of eight patients have been enrolled and infused in cohort 1 of a blinded Phase 1 clinical trial of GR-MD-02 for patients with NASH with advanced fibrosis. Enrollment continues and no serious adverse events have been reported. The Phase 1 first-in-man study is evaluating the safety, tolerability, pharmacokinetics and exploratory biomarkers for efficacy for single and multiple doses of GR-MD-02 when administered to patients with fatty liver disease with advanced fibrosis. Clinical data from the first cohort is expected early in 2014.

About Fatty Liver Disease with Advanced Fibrosis

Non-alcoholic steatohepatitis (NASH), also known as fatty liver disease, has become a common disease of the liver with the rise in obesity rates, estimated to affect nine to 15 million people, including children, in the U.S. Fatty liver disease is characterized by the presence of fat in the liver along with inflammation and damage in people who drink little or no alcohol. Over time, patients with fatty liver disease can develop fibrosis, or scarring of the liver, and it is estimated that as many as three million individuals will develop cirrhosis, a severe liver disease where liver transplantation is the only current treatment available. Approximately 6,300 liver transplants are done on an annual basis in the U.S. There are no drug therapies approved for the treatment of liver fibrosis.

Forward Looking Statements

This press release contains, in addition to historical information, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements relate to future events or future financial performance, and use words such as "may," "estimate," "could," "expect" and others. They are based on our current expectations and are subject to factors and uncertainties which could cause actual results to differ materially from those described in the statements. These statements include those regarding preclinical data and the potential role for GR-MD-02 and GM-CT-01 in the treatment of liver fibrosis and cirrhosis in humans. Factors that could cause our actual performance to differ materially from those discussed in the forward-looking statements include, among others, that our plans, expectations and goals regarding any preclinical data and potential therapeutic uses and benefits of our drugs and any future pre-clinical or clinical studies are subject to factors beyond our control. Future clinical studies may not begin or produce positive results in a timely fashion, if at all, and could prove time consuming and costly. Plans regarding development, approval and marketing of any of our drugs are subject to change at any time based on the changing needs of our company as determined by management and regulatory agencies. Regardless of the results of current or future studies, we may be unsuccessful in developing partnerships with other companies or obtaining capital that would allow us to further develop and/or fund any studies or trials. To date, we have incurred operating losses since our inception, and our ability to successfully develop and market drugs may be impacted by our ability to manage costs and finance our continuing operations.
