Gilead Sciences Inc. and Phenex Pharmaceuticals AG have signed an agreement under which Gilead will acquire Phenex’s Farnesoid X Receptor (FXR) program comprising small molecule FXR agonists for the treatment of liver diseases including nonalcoholic steatohepatitis (NASH). Gilead will pay Phenex an upfront payment plus additional payments based upon certain development milestones that may potentially be worth up to $470 million.
“This agreement represents a significant milestone for our company and for the field of liver disease research,” said Dr. Claus Kremoser, CEO of Phenex Pharmaceuticals AG. “After 15 years of research, FXR is now one of the few clinically validated targets for NASH and we are delighted that Gilead will be continuing the research necessary to more fully realize its potential for advanced liver disease.”
“The acquisition of Phenex’s FXR program represents an important opportunity to accelerate Gilead’s efforts to develop new treatment options that address fibrotic liver diseases,” said Norbert W. Bischofberger, PhD, Gilead’s Executive Vice President, Research and Development and Chief Scientific Officer. “We look forward to working closely with Phenex’s research and development team to advance the FXR program into clinical development as quickly as possible to explore its potential in areas of significant unmet need.”
