Press Release

NORCROSS, Ga., Jan. 21, 2014 (GLOBE NEWSWIRE) -- Galectin Therapeutics Inc. (Nasdaq:GALT), the leading developer of therapeutics that target galectin proteins to treat fibrosis and cancer, today announced that data from a preclinical study show its leading galectin-inhibiting drug GR-MD-02 demonstrates an effect on a blood biomarker in an animal model of nonalcoholic steatohepatitis (NASH, or fatty liver disease) with fibrosis. Hyaluronic acid, a well investigated marker of liver fibrosis, was significantly reduced by approximately 33 percent when untreated animals were compared with those treated with GR-MD-02.

In the study, NASH-induced mice were treated with once weekly doses of GR-MD-02 at four different doses for a total of six weeks of treatment. Results revealed that treatment with GR-MD-02 at doses of 10, 30, and 60 mg/kg body weight significantly reduced the plasma levels of hyaluronic acid in the NASH mice. Other biomarkers examined did not change (MIG (monokine induced by interferon gamma) and TIMP-1 (tissue inhibitor of metalloproteinase)) or were not detectable (IP-10 (interferon inducible protein), KC (keratinocyte-derived chemokine), MIP-1α (macrophage inflammatory protein), and MCP-1 (monocyte chemo-attractant protein). Importantly, plasma levels of galectin-3 were measurable and did not change with therapy, indicating that changes in tissue galectin-3 and improvement in NASH histology do not correlate with blood levels of galectin-3 in this model.

"These results in this preclinical model of NASH show that improvement in NASH and fibrosis with GR-MD-02 treatment appear to correlate with plasma levels of hyaluronic acid, a biomarker that has been shown in multiple human studies to correlate with liver fibrosis," said Peter G. Traber, M.D., Chief Executive Officer, President and Chief Medical Officer, Galectin Therapeutics. "We are examining the levels of hyaluronic acid as well as multiple other markers of inflammation, cell death and fibrosis in our current Phase 1 clinical trial of GR-MD-02 in NASH patients with advanced fibrosis."

As previously reported and published in PLOS ONE, the same study showed that GR-MD-02 improved all components of NASH in mice, including fibrosis [http://dx.plos.org/10.1371/journal.pone.0083481].

GR-MD-02 is a proprietary molecule that binds to and inhibits galectin proteins, predominantly galectin-3. Patient enrollment is complete in cohort 1 of a blinded Phase 1 clinical trial of GR-MD-02 for patients with NASH with advanced fibrosis. 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. Following the 70 day study period and analysis of the data, the Company anticipates that initial safety and tolerability results, as well as biomarkers to evaluate for potential disease effect, from the first cohort will be available around the end of the first quarter of this year.

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.
