Gilead Sciences acquires Phenex Pharmaceuticals’ NASH development program
January 7, 2015
Gilead Sciences, a biopharmaceutical company headquartered in Foster City, Calif., and Phenex Pharmaceuticals, a privately held German biotechnology company, have signed a definitive 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 achievement of certain development milestones that may potentially be worth up to $470 million.
NASH is a common, serious chronic liver disease characterized by inflammation and excessive fat accumulation in the liver and may lead to progressive fibrosis, cirrhosis and liver failure. NASH is estimated to affect 10% to 20% of people in the developed world. There currently are no approved therapies to treat NASH. FXR is a nuclear hormone receptor that regulates bile acid, lipid and glucose homeostasis, which can help reduce liver steatosis and inflammation, and may help prevent liver fibrosis.
“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. “After 15 years of research, FXR now is 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, Ph.D., Gilead’s executive vice president, R&D and chief scientific officer. “We look forward to working closely with Phenex’s R&D team to advance the FXR program into clinical development as quickly as possible to explore its potential in areas of significant unmet need.”
