Press Release

NORCROSS, Ga., March 14, 2017 (GLOBE NEWSWIRE) -- Galectin Therapeutics Inc.(NASDAQ:GALT), the leading developer of therapeutics that target galectin proteins, today announced preliminary results for severe and refractory atopic dermatitis from a small, open label, investigator-initiated study with GR-MD-02 that has enrolled 3 patients. There were no serious adverse events observed.  All three patients showed clinical response as determined by reduction of the Eczema Area and Severity Index (EASI) score at week 12 having received 6 every other week doses, with two patients achieving a 64% and 74% reduction in EASI, respectively, at six weeks after receiving only 3 doses of GR-MD-02 (see graph below). These findings are believed to demonstrate a clinically significant effect of this novel investigational drug in this patient population. More information and commentary on these findings can be found in a simultaneously released CEO Perspective: http://perspectives.galectintherapeutics.com/galectin-inhibitor-therapy-effective-severe-atopic-dermatitis-eczema/.

Simon A. Ritchie, M.D., FAAD, lead investigator and staff dermatologist, San Antonio Military Health System, Fort Sam Houston, TX, said "There is a lack of effective therapy currently on the market for patients with severe, refractory atopic dermatitis. As a galectin-3 inhibitor, GR-MD-02, represents a novel mechanism for treatment in patients with severe atopic dermatitis that have failed standard of care. The significant clinical effect we have seen from preliminary results in this investigator-initiated protocol is encouraging and warrants a phase 2 controlled trial with various doses and regimens to further explore the drug's potential." 

The small, open label, investigator-initiated protocol treated three adult patients with severe atopic dermatitis. All three patients had failed a number of systemic therapies and would be classified as refractory, meaning that they have not responded to medical treatment beyond topical steroids. The disease severity was determined using EASI, an objective scoring system in common use for atopic dermatitis studies. GR-MD-02 was given intravenously at a starting dose of 8 mg/kg at baseline and then every other week for 10 weeks (6 infusions) and then increased to 12 mg/kg every other week for an additional 7 infusions. All three patients experienced improvement in their atopic dermatitis, with patient 1 achieving a 64% reduction in EASI at 24 weeks, the time of his 13^th infusion. While patient 1 has completed the full 13 infusions, patients 2 and 3 have just started the higher dose of 12 mg/kg. It should be noted that patient 1 has elected to remain on 24 additional weeks of therapy because of the positive effect on his clinical symptoms.

"We are pleased by the results of this study demonstrating the safety and clinically significant effect in patients with severe atopic dermatitis, although because of the potential of a placebo effect in this disease, confirmation of the magnitude of the effect will require placebo-controlled trials," said Peter G. Traber, M.D., president, chief executive officer and chief medical officer, Galectin Therapeutics.  "Moreover, the activity of GR-MD-02 in these patients compares favorably with other drugs currently in development, and with minimal side effects as demonstrated by nearly 3,000 doses of our compound being administered in multiple completed and ongoing clinical trials with no severe adverse effects attributed to the drug."

About Atopic Dermatitis
Atopic dermatitis, commonly called eczema, is a chronic inflammatory condition of the skin of caused by multiple factors that usually arises in early childhood, often in infancy. While it usually resolves by early teenage years, approximately 5-10% of patients have the disease extend into adulthood. Classic symptoms are itching and burning of the skin, resulting in thickening of the skin in response to the scratching. In some adults, it can be severe with debilitating itching, inability to sleep, and social stigmatization due to skin damage and thickening, often on the face.

Surveys suggest that up to 18% of the population have atopic dermatitis, up to 37% of those people seek medical care, and over 70% of those seeking care have mild disease that is handled by primary care physicians. Approximately 20% with mild and 2% with severe disease are referred to specialists. The national estimated cost of treatment is as high as $3.8 billion, as of 2012.

About GR-MD-02
GR-MD-02 is a complex carbohydrate drug that targets galectin-3, a critical protein in the pathogenesis of fatty liver disease and fibrosis. Galectin-3 plays a major role in diseases that involve scarring of organs including fibrotic disorders of the liver, lung, kidney, heart and vascular system. The drug binds to galectin proteins and disrupts their function. Preclinical data in animals have shown that GR-MD-02 has robust treatment effects in reversing liver fibrosis and cirrhosis.

About Galectin Therapeutics
Galectin Therapeutics is dedicated to developing novel therapies to improve the lives of patients with chronic liver and skin diseases and cancer. Galectin's lead drug (GR-MD-02) is a carbohydrate-based drug that inhibits the galectin-3 protein which is directly involved in multiple inflammatory, fibrotic, and malignant diseases. The lead development program is in non-alcoholic steatohepatitis (NASH) with cirrhosis, the most advanced form of NASH related fibrosis. This is the most common liver disease and one of the largest drug development opportunities available today. Additional development programs are in treatment of severe atopic dermatitis, moderate-to-severe plaque psoriasis, and in combination immunotherapy for advanced melanoma and other malignancies. Galectin seeks to leverage extensive scientific and development expertise as well as established relationships with external sources to achieve cost-effective and efficient development.  Additional information is available at www.galectintherapeutics.com.
