Nivocasan (aka GS-9450) was discovered by LG Life Sciences and developed by Gilead Sciences. Nivocasan is an irreversible inhibitor of caspase 1, 8, and 9, and therefore able to prevent apoptosis. Nivocasan has been investigated as a treatment option for Hepatic fibrosis and Non-alcoholic steatohepatitis related to Hepatitis C infection. It had advanced to Phase II clinical trials before the development program was suspended.
