Conatus Pharmaceuticals’ IDN-7314 Pan-caspase Inhibitor Reduces Hepatic Tissue Factor-Driven Coagulation In Vitro and In Vivo

SAN DIEGO, April 18, 2018 (GLOBE NEWSWIRE) -- Conatus Pharmaceuticals Inc. (Nasdaq:CNAT), a biotechnology company focused on the development and commercialization of novel medicines to treat liver disease, today announced the publication1 of results from both in vitro and in vivo studies of its pan-caspase inhibitor, IDN-7314, demonstrating reductions of hepatic tissue factor-driven coagulation.

Patients with liver cirrhosis can suffer caspase-driven complications of both excessive bleeding and excessive clotting. The current studies suggest that a pan-caspase inhibitor may have the potential to reduce excessive clotting in patients with severe liver disease.

The studies were conducted under the sponsorship of Conatus in collaboration with the Department of Pathobiology & Diagnostic Investigation and the Institute for Integrative Toxicology at Michigan State University. “We were intrigued to learn that caspase inhibition, by preventing apoptosis-associated release of hepatocyte tissue factor, may reduce the risk of thrombosis in patients with cirrhosis,” said Al Spada, Ph.D., Executive Vice President of Research and Development, Chief Scientific Officer and co-founder of Conatus, and a co-author on the publication. “These data encourage further study to evaluate the potentially normalizing hematological effects of caspase inhibition in the context of severe liver disease.”

Both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have granted Orphan Drug Designation to IDN-7314 for the treatment of primary sclerosing cholangitis (PSC), a disease affecting bile ducts in the liver which can lead to cirrhosis and liver failure. IDN-7314 is an orally active pan-caspase protease inhibitor designed to reduce the activity of enzymes that mediate inflammation and cell death (apoptosis), which has demonstrated reduction of relevant biomarkers in two preclinical models of PSC. Conatus is evaluating the potential of IDN-7314 as a treatment for PSC.

About Conatus Pharmaceuticals
Conatus is a biotechnology company focused on the development of novel medicines to treat liver disease. In collaboration with Novartis, Conatus is developing its lead compound, emricasan, for the treatment of patients with chronic liver disease. Emricasan is a first-in-class, orally active pan-caspase inhibitor designed to reduce the activity of enzymes that mediate inflammation and apoptosis. Conatus believes that by reducing the activity of these enzymes, caspase inhibitors have the potential to interrupt the progression of a variety of diseases. For additional information, please visit
