SAN DIEGO, April 30, 2019 (GLOBE NEWSWIRE) -- Conatus Pharmaceuticals Inc. (Nasdaq:CNAT) today announced a new publication1 in Hepatology Communications detailing results following seven-day treatment with emricasan, the company’s first-in-class pan-caspase inhibitor, in rats with advanced cirrhosis including increased portal pressure induced by chronic carbon tetrachloride administration. Portal pressure was significantly reduced in emricasan-treated rats relative to vehicle-treated control animals. Reduced portal pressure was associated with significantly better liver function, reduced liver inflammation, and reduced fibrosis. Improvements in expression of markers of liver function, including increased expression of vasodilators and reduced expression of vasoconstrictors, were observed in liver cells isolated from emricasan-treated cirrhotic rats. In vitro experiments treating human cirrhotic liver cells with emricasan improved the synthetic capacity of hepatocytes from cirrhotic livers and increased expression of specific markers of liver function.
The publication’s authors concluded that, “This study demonstrates that emricasan improves liver sinusoidal microvascular dysfunction in cirrhosis, which leads to marked amelioration in fibrosis, portal hypertension and liver function, and therefore encourages its clinical evaluation in the treatment of advanced chronic liver disease.”
“The current study provides mechanistic support for the results from clinical studies evaluating emricasan’s ability to reduce portal hypertension in patients with advanced cirrhosis,” said Al Spada, Ph.D., Executive Vice President of Research and Development, Chief Scientific Officer and co-founder of Conatus, and an author on the publication. “We believe the insights provided by the cumulative body of preclinical data, coupled with the corresponding results from human clinical testing, support continued evaluation in NASH cirrhosis patients.”
Emricasan Clinical Development
The company is currently conducting two double-blind, placebo-controlled Phase 2b clinical trials in collaboration with Novartis – the EmricasaN, a Caspase inhibitOR, for Evaluation (ENCORE) trials, designed to evaluate emricasan in patients with liver cirrhosis caused by nonalcoholic steatohepatitis (NASH).
