A China-U.S. study led by scientists at China Pharmaceutical University (CPU) and Harvard University has identified a new small-molecule antagonist of the stimulator of interferon genes (STING) signaling pathway, SN-011, and shown it to be safe, effective and specific in STING-driven inflammatory diseases.

The agreement between gout player Horizon plc and RNAi expert Arrowhead Pharmaceuticals Inc. could result in a subcutaneously given, infrequently dosed fix for the disease that takes aim at xanthine dehydrogenase. “They brought us the target – it wasn’t something we were developing,” said Arrowhead CEO Christopher Anzalone, but the Pasadena, Calif.-based firm’s research on hepatocyte-directed therapies provides confidence.
