Larger Phase 2b clinical trial in NASH cirrhosis (NASH-CX) now completely enrolled
Closed private placement financing for $1.5 million
Conference call to be held today at 5:30 p.m. (Eastern Time)
NORCOSS, Ga., Sept. 27, 2016 (GLOBE NEWSWIRE) -- Galectin Therapeutics Inc. (NASDAQ:GALT), the leading developer of therapeutics that target galectin proteins to treat fibrosis and cancer, today announced topline results from NASH-FX, its Phase 2a clinical trial evaluating the efficacy, safety, and tolerability of GR-MD-02 in 30 nonalcoholic steatohepatitis (NASH) patients with advanced fibrosis. This exploratory, single site, short-treatment (four months of therapy), randomized study did not meet its primary biomarker endpoint as measured by LiverMultiScan (LMS, Perspectum Diagnostics), a magnetic resonance imaging test that evaluates inflammation and fibrosis. The trial also did not meet secondary endpoints that measure liver stiffness as a surrogate for fibrosis, with FibroScan® and magnetic resonance elastography (MRE). While all patients had a baseline liver biopsy to establish the diagnosis and fibrosis severity, liver biopsies were not performed at the end of the study following treatment due to safety considerations involved with liver biopsy-related risk in a short duration trial. GR-MD-02 was found to be safe and well tolerated among the patient population with no serious adverse events.
Importantly, Galectin simultaneously announced that the principal focus of its research efforts—its larger scale, one-year, multi-site trial in patients with NASH cirrhosis (NASH-CX)—has completed enrollment one month early with 162 total subjects (exceeding the target of 156 patients), allowing for reporting of top-line results in December 2017. In further contrast to the NASH-FX trial, the NASH-CX trial is being conducted with a primary endpoint (hepatic venous pressure gradient (HVPG)) which the U.S. Food and Drug Administration may view as an acceptable surrogate for outcomes for registration trials in this patient population.
“Although there was no apparent improvement in the three non-invasive tests for assessment of liver fibrosis in this four month pilot trial, inhibition of galectin-3 with GR-MD-02 remains promising for treatment of NASH fibrosis,” said Stephen A. Harrison, M.D., the principal investigator (PI) of the NASH-FX trial, medical director of Pinnacle Clinical Research in San Antonio, TX, and visiting professor of medicine at the University of Oxford, UK. “In regard to the potential activity of GR-MD-02, it is encouraging that there is an important clinical effect in moderate-to-severe psoriasis, suggesting the compound has activity in a human disease that can occur in association with NASH.”
Dr. Harrison, who is also the co-lead PI of the NASH-CX trial, continued, “The NASH-FX trial was designed to follow up on limited data from a Phase 1 study in NASH with advanced fibrosis, which suggested that FibroScan® measurements may have improved with just four doses of drug. However, as we have witnessed in other liver fibrosis trials, the relatively short treatment duration of only four months assessed in the NASH-FX was inadequate to see an efficacy response. Therefore, we look forward to additional results from the NASH-CX trial in which patients with NASH cirrhosis are treated for one year.”
Naga Chalasani, M.D., the other co-lead PI of the NASH-CX trial and chief of the Division of Gastroenterology and Hepatology at Indiana University, said, “In my assessment, the results from the NASH-FX trial do not diminish the significance of the NASH-CX trial. Along with the safety and tolerability profile observed in the NASH-FX trial, the different patient population, much larger enrollment, rigorous study design and longer duration of therapy offer compelling rationale to complete the NASH-CX trial.”
With over 1,600 drug doses administered there is now substantial clinical trial experience with GR-MD-02. There is no evidence of serious adverse effects related to the drug, highlighting the good safety profile of the therapy in this patient population with advanced stage disease. In the NASH-CX trial 64 patients have already completed 6 months of dosing with a low drop-out rate of only 3 patients prematurely exiting the trial.
In support for continued funding of the NASH-CX trial, a private placement financing for $1.5 million from a single source was signed on September 22, 2016. “It is encouraging that we have the confidence of a highly-respected businessman such as Mr. Richard Uihlein, who has now invested $1.5 million in Galectin through a limited partnership investment fund, which adds to his current significant stake in the company,” added Peter Traber, M.D., Galectin's president, chief executive officer and chief medical officer. “Mr. Uihlein is further committed to helping the company progress through the completion of the NASH-CX trial. We will continue to pursue the additional funding required to support our clinical development program.”

About NASH-CX Trial
Galectin announced in August the completion of patient recruitment ahead of original expectations in the NASH-CX trial, its Phase 2b clinical trial with GR-MD-02 in patients with NASH with cirrhosis. The Company has enrolled 162 liver biopsy-confirmed NASH cirrhosis patents into the treatment phase, with the original goal to enter 156 patients. Enrolled patients are receiving either 8 mg/kg or 2 mg/kg of GR-MD-02 or placebo every other week for 52 weeks, for a total of 26 doses. The primary study endpoint is a reduction of hepatic venous pressure gradient (HVPG). Patients treated with GR-MD-02 will be evaluated to determine the change in HVPG as compared to patients treated with placebo. HVPG will be correlated with secondary endpoints of liver biopsy fibrosis staging at baseline and the end of the trial, measurement of liver stiffness (FibroScan®), and assessment of liver metabolism (13C-methacetin breath test, Exalenz). The Company projects topline results of this trial will be available in December 2017. More information on the NASH-CX trial may be found in a post on Dr. Traber's blog, CEO Perspectives and at www.clinicaltrials.gov.
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 Fatty Liver Disease with Advanced Fibrosis and Cirrhosis
Non-alcoholic fatty liver disease (NAFLD) has become the most common disease of the liver, generally associated with the rise in obesity rates. NAFLD is characterized by the presence of fat in the liver in people who consume little or no alcohol, and when associated with inflammation and cell damage is called non-alcoholic steatohepatitis (NASH). Over time, patients with NASH can develop fibrosis, or scarring of the liver, which may progress to severe fibrosis, called cirrhosis. Approximately one in four people in the world have NAFLD, with 5% of those developing cirrhosis, and 2% eventually dying of the disease. These data translate into ~20,000,000 liver-related deaths among patients currently alive with NAFLD. There are no drug therapies approved for the treatment of NASH, liver fibrosis, or cirrhosis, for which liver transplant is the only treatment available. A recent analyst estimate indicated that by 2025 the worldwide market for NASH treatments could approach $35 billion.
