The Study, which is a Phase IIa trial, will be conducted under the leadership of principal investigator, Andrea Branch, PhD, Professor of Medicine in the Icahn School of Medicine at Mount Sinai, United States, and an additional center in Israel. Galmed has filed a patent application for the composition of matter patent on the new combination therapy.
The Study will enroll 80 patients with NAFLD and fibrosis, and is anticipated to be completed in the first half of 2018. The Study design includes four dose alternatives: (a) AramcholTM 400 mgs, (b) Vitamin D, (c) AramcholTM 400 mgs and Vitamin D in combination, and (d) Placebo, administrated for 24 weeks, followed by a 4-week follow-up period.
The Study’s primary endpoint is the change in liver stiffness (baseline to end of treatment), measured by Magnetic Resonance Elastography (MRE). Secondary endpoints include changes in the intrahepatic fat content (measured by MRI and FibroScan/CAP), and other metabolic parameters.
According to a recent study published in American Journal of Gastroenterology, "[vitamin D deficiency] in humans and animal models indicate that [vitamin D deficiency] also contributes to increased oxidative stress, systemic inflammation, decreased adiponectin levels, toll-like receptor activation, and nonalcoholic fatty liver disease … we have found that [vitamin D deficiency] in our NAFLD subjects was associated with a definitive diagnosis of NASH, increased lobular inflammation, more ballooning and the presence of fibrosis." [Nelson JE, et. al. Am J Gastroenterol 2016;doi:10.10385/ajg.2016.51].
According to Dr. Branch, "The liver is a key regulator of lipid metabolism and frequently becomes inflamed and damaged in patients with metabolic abnormalities, including type-2 diabetes and obesity. AramcholTM, a bile acid-fatty acid conjugate, was previously shown to decrease liver fat.
"Vitamin D3 is a key regulatory hormone that reduces inflammation and improves the barrier function of the intestine, potentially protecting the liver from harmful bacterial products that would otherwise reach the liver and cause injury.
"In addition to the innovative dual therapy, the trial has several more novel features: It will be open to patients with NASH and well-compensated liver cirrhosis (unlike many trials that exclude these patients), as well as to patients with less extensive liver damage, and it will not require a liver biopsy for participation."
Dr. Branch continued, "I am excited to be conducting this study with Galmed and with my colleagues at Mount Sinai, including Dr. Meena Bansal, the study hepatologist, Dr. Charissa Chang, an expert in the clinical management of NASH, and Drs. Sara Lewis and Bachir Taouli, who are innovators in liver imaging.
"In addition to clinical endpoints, the study will provide information about the impact of AramcholTM and vitamin D3 on the intestinal flora comprising the microbiome." Dr. Branch concluded, "These studies will be carried out in collaboration with Dr. Inga Peter and her research team in the Department of Genetics and Genomic Sciences at the Icahn School of Medicine at Mount Sinai."
Galmed Pharmaceuticals President and Chief Executive Officer, Allen Baharaff added, "As we’ve discussed for some time, Galmed is seeking to address the treatment of NASH through a comprehensive portfolio approach, rather than a single "shot-on-goal"; a combination therapy, now with Vitamin D, fits perfectly into that strategy.
"NASH is a complex, multifactorial disease, which requires therapeutic approaches with multiple mechanisms of action." Mr. Baharaff concluded, "We will continue to investigate compounds complementary to AramcholTM, including safe, FDA-approved compounds repositioned to treat fibrosis, as well as new chemical entities aiming to develop an ultimate treatment for NASH."
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the United States and it affects almost 30% of adults in Western countries.
With climbing obesity rates and more sedentary patient populations, the prevalence of NAFLD is increasing worldwide and is becoming the predominant cause of chronic liver disease in parts of the world. NAFLD represents a spectrum of diseases ranging from simple excess liver fat, or steatosis, to nonalcoholic steatohepatitis (NASH). NASH is the progressive form of fatty liver disease that can lead to cardiovascular disease, cirrhosis and liver-related mortality in persons who drink little or no alcohol.
NASH represents the more severe end of this spectrum and is characterized by steatosis, ballooning degeneration and lobular inflammation with or without fibrosis. Long-term risks of NASH include cardiovascular disease, cirrhosis, hepatocellular carcinoma and end stage liver disease requiring liver transplantation.
