Galectin Therapeutics Receives U.S. Patent Allowance for GR-MD-02 to Treat Pulmonary Fibrosis

NORCROSS, Ga. , Feb. 24, 2016 (GLOBE NEWSWIRE) -- Galectin Therapeutics, Inc. (NASDAQ:GALT), the leading developer of therapeutics that target galectin proteins to treat fibrosis and cancer, announces receipt of a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for patent application number 13/999,389, titled "Method for Treatment of Pulmonary Fibrosis." When issued, the patent will extend coverage of the Company's lead compound, GR-MD-02, to treat patients at risk of pulmonary fibrosis. In pulmonary fibrosis, scars are formed in the lung tissue, which leads to serious breathing problems. This patent allowance covers the treatment of primary lung fibrosis, including idiopathic pulmonary fibrosis, as well as secondary lung fibrotic disease.

GR-MD-02, a proprietary polysaccharide pharmaceutical preparation that inhibits galectin proteins, is currently in two Phase 2 clinical trials in subjects with non-alcoholic steatohepatitis (NASH) with cirrhosis and NASH with advanced fibrosis, as well as in preclinical testing for lung, kidney and cardiovascular fibrosis. GR-MD-02 is also being studied in two clinical trials at Providence Portland Medical Center in advanced melanoma patients in combination with Keytruda® and in combination with Yervoy®, as well as in a Phase 2a trial in moderate to severe plaque psoriasis.   

"We are pleased to further bolster our intellectual property portfolio with this patent allowance, which expands our portfolio to include pulmonary fibrosis," said Peter G. Traber, M.D., chief executive officer and chief medical officer of Galectin Therapeutics and inventor on the patent. "Scientific evidence shows that Galectin-3 plays a role in pulmonary fibrosis and we have shown that GR-MD-02 is effective in reducing fibrosis in preclinical models of lung fibrosis. There are currently no effective treatments for this disease, and particularly for idiopathic pulmonary fibrosis, an orphan indication. When issued, this patent will augment our current intellectual property portfolio for treatment of organ fibrosis, and we look forward to opportunities to leverage this towards a more efficacious treatment in lung fibrotic disease."
