Galectin Therapeutics Receives Notice of Chinese Allowance to Grant a Key Patent for Composition of Matter for GR-MD-02

NORCROSS, Ga., Sept. 12, 2017 (GLOBE NEWSWIRE) -- Galectin Therapeutics, Inc. (NASDAQ:GALT), the leading developer of therapeutics that target galectin proteins, today announced that the Company has received a Decision to Grant from the Chinese Patent Office for its patent application for "Composition of Novel Carbohydrate Drug for Treatment of Human Diseases." When issued, the patent will extend composition of matter coverage of the Company's lead compound, GR-MD-02, to China. The patent coverage period extends through 2032. This is one of more than 50 patent applications Galectin Therapeutics, Inc. has pending in 10 foreign countries.

GR-MD-02, a proprietary polysaccharide pharmaceutical preparation that inhibits galectin proteins, is currently in a Phase 2 clinical trial in subjects with NASH with cirrhosis and is 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, oral neck and head cancer and selected lung cancer patients in combination with Keytruda® and Yervoy®. Additionally, GR-MD-02 has been studied in two Phase 2 trials with promising results in patients with severe skin diseases, including moderate-to-severe plaque psoriasis and atopic dermatitis.

"The allowance of these key composition of matter claims in China further strengthens the protection of the intellectual property behind our proprietary compound, GR-MD-02.  This is especially important in China, which is a very large potential market for treatment of liver fibrosis. The prevalence of patients with fatty liver disease in China has approximately doubled over the past two decades, with around 15% of the population experiencing NASH1," said Peter G. Traber, M.D., chief executive officer and chief medical officer of Galectin Therapeutics and inventor on the patent.
