Novartis announced the signing of an exclusive option, collaboration and license agreement with Conatus Pharmaceuticals Inc., a biotechnology company focused on the development of novel medicines to treat liver disease. This agreement will enable Novartis and Conatus to jointly develop emricasan. Emricasan is an investigational, first-in-class, oral, pan-caspase inhibitor for the treatment of non-alcoholic steatohepatitis (NASH) with advanced fibrosis (scarring) and cirrhosis. This collaboration has the potential to expand treatment options for people in various stages of fatty liver disease, where no approved medicines currently exist.
