Galectin Therapeutics Initiates Enrollment for GR-MD-02 Phase 2 Clinical Trial in NASH with Cirrhosis

First Five Patients Screened

Jun. 29, 2015 7:45 am

NORCROSS, Ga., June 29, 2015 (GLOBE NEWSWIRE) -- Galectin Therapeutics Inc. (NASDAQ:GALT), a leading developer of therapeutics that target galectin proteins to treat fibrosis and cancer, today announced the screening of the first five patients in its Phase 2 clinical trial with GR-MD-02 in nonalcoholic steatohepatitis (NASH) with cirrhosis. This study, the NASH-CX trial, is a multicenter, randomized, placebo-controlled, double-blind, parallel-group Phase 2 trial to evaluate the safety and efficacy of GR-MD-02 for the treatment of liver fibrosis and resultant portal hypertension in patients with NASH cirrhosis.

Co-lead investigators are Stephen A. Harrison, M.D., FACP, Colonel, Medical Corps U.S.A., Director, Medical Education, Associate Dean, San Antonio Uniformed Services Health Education Consortium, Professor of Medicine, Uniformed Services University of the Health Sciences Consultant to The Surgeon General for Gastroenterological Diseases, Brooke Army Medical Center /San Antonio Military Medical Center; and, Naga Chalasani, MD, FACG, David W. Crabb Professor & Director, Division of Gastroenterology and Hepatology, Indiana University School of Medicine.

"We are very excited that patient screening has begun in our NASH-CX Phase 2 study, the larger of the two trials comprising our Phase 2 program," said Peter G. Traber, M.D., president, chief executive officer and chief medical officer of Galectin Therapeutics. "We are delighted that Drs. Harrison and Chalasani have agreed to serve as co-lead investigators, as they are important thought leaders in field of NASH. Indeed Dr. Harrison is an associate editor for Hepatology, the official journal of the American Association for the Study of Liver Diseases, and Dr. Chalasani has well over 100 published papers on NASH and other diseases of the liver."

"We have worked diligently along with PPD, our contract research organization, to advance to this point in our development. PPD has extensive experience in conducting clinical trials in NASH and cirrhosis, and we are very pleased with the pace of site recruitment. In addition, these sites have experience with measuring hepatic venous pressure gradient (HVPG), our primary endpoint, which is reflective of clinical outcomes in cirrhosis.  We will correlate HVPG with liver biopsy as a secondary endpoint both at the beginning and the completion of the 52-week treatment period. In addition, non-invasive tests as secondary endpoints will be conducted at the beginning, middle and end of the study."

Dr. Traber continued, "Our preclinical research shows that GR-MD-02 binds to Galectin-3, a well-validated target, and our work in preclinical models suggests that GR-MD-02 reverses liver fibrosis and cirrhosis. As a result of the preclinical observations in disease that we noted, we are concentrating our Phase 2 study in the most ill patients – Stage 4 on the NASH spectrum –as these patients have an increased mortality.

"Our two completed Phase 1 trials provide a strong foundation for our NASH Phase 2 program. In a multiple dose-escalation, double-blind, placebo-controlled trial, we found GR-MD-02 to be safe and well tolerated, and noted that the highest dose, 8 mg/kg, may have had an effect on fibrosis as shown by reduced serum alpha-2 macroglobulin, a marker of fibrosis, and reduced liver stiffness as assessed by FibroScan®. In addition, in a drug-drug interaction study between GR-MD-02 and midazolam, a commonly used sedative, there was no interaction, suggesting an additional layer of safety," Dr. Traber added.

Dr. Traber continued, "The commercial potential of a drug that treats late stage fibrosis and cirrhosis should be excellent. While many other companies are investigating therapeutics in early, low stage fibrosis NASH, we believe that the sense of urgency for treatment by physicians, patients and payors will be less robust than that of late stage NASH with its heightened mortality. In fact, the scope of this disease is such that by 2025 the worldwide market for NASH treatments could approach $35 billion, according to a recent biotech analyst report," he concluded.

About the NASH-CX Study

A total of 156 patients at between 45 and 60 sites will be randomized to receive either 2 mg/kg of GR-MD-02, 8 mg/kg of GR-MD-02 or placebo, with 52 patients in each arm. The primary endpoint is a reduction in HVPG. Patients will receive a total of 26 infusions every other week for one year and will be evaluated to determine the change in HVPG as compared with placebo.  HVPG will be correlated with secondary endpoints of fibrosis on liver biopsy as well as with measurement of liver stiffness (FibroScan®) and assessment of liver metabolism (13C-methacetin breath test, Exalenz), which are non-invasive measures of the liver that may be used in future studies. Data readout is expected in the fourth quarter of 2017.

About the NASH-FX Study

The Company also expects to begin screening patients with advanced fibrosis (the NASH-FX trial) in a smaller, 30 patient study in August 2015, with 15 patients receiving 8 mg/kg of GR-MD-02 and 15 receiving placebo. That study will evaluate the safety and efficacy of GR-MD-02 on liver stiffness as assessed by magnetic resonance-elastography and FibroScan score, and on imaging of liver fibrosis using multi-parametric magnetic resonance imaging (LiverMultiScan®, Perspectum Diagnostics). Top-line data is expected to be available in mid-2016.

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 scaring 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 Fatty Liver Disease with Advanced Fibrosis and Cirrhosis

Non-alcoholic steatohepatitis (NASH), also known as fatty liver disease, has become a common disease of the liver with the rise in obesity rates. NASH is estimated to affect up to 28 million people 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 consume 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 1-2 million individuals in the U.S. will develop cirrhosis, a severe liver disease for which liver transplantation is the only treatment available. Approximately 6,300 liver transplants are performed annually in the U.S. There are no drug therapies approved for the treatment of liver fibrosis.
