Galectin Therapeutics Receives Notice of Japanese Decision to Grant a Composition of Matter Patent for GR-MD-02

NORCROSS, Ga., April 25, 2017 -- Galectin Therapeutics, Inc. (NASDAQ:GALT), the leading developer of therapeutics that target galectin proteins to treat fibrosis, skin diseases, and cancer, today announced that the Company has received a Decision to Grant from the Japanese Patent Office for its patent application for "Composition of Novel Carbohydrate Drug for Treatment of Human Diseases." When issued, the patent will extend coverage of the Company's lead compound, GR-MD-02, to Japan. The patent coverage period extends through 2032.

GR-MD-02, a proprietary polysaccharide pharmaceutical preparation that inhibits galectin proteins, is currently in a Phase 2b clinical trial in subjects with NASH cirrhosis and is in preclinical testing for lung, kidney and cardiovascular fibrosis. GR-MD-02 is also being studied in two phase 1b 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 is being studied in two Phase 2a trials in patients with severe skin diseases, including moderate-to-severe plaque psoriasis and atopic dermatitis.

"The allowance of these claims in Japan further strengthens the protection of the intellectual property behind our proprietary compound, GR-MD-02.  This is especially important in Japan, which was recently declared the second most attractive drug market in the world. In 2016, Japan’s pharmaceutical market was the 3^rd largest globally, behind only China and the United States," said Peter G. Traber, M.D., chief executive officer and chief medical officer of Galectin Therapeutics and inventor on the patent. "This is but one of more than 50 patent applications we have pending in 10 foreign countries, including Brazil, Canada, China, Europe, Israel, Korea, Mexico and South Africa. When issued, this patent will augment our current intellectual property portfolio for treatment of all indications with GR-MD-02 in Japan. ."
