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.

“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.
