Compound class: Synthetic organic
Comment: Firsocostat (GS-0976) is a liver-directed acetyl-CoA carboxylase (ACC) inhibitor [2]. It was initially identified by Nimbus Therapeutics [3], and is being developed by Gilead as an antilipemic agent for potential to treat non-alcoholic steatohepatitis (NASH) [1]. Firsocostat is an allosteric inhibitor that binds to the ACC biotin carboxylase dimerization site, rather than to the previously targeted carboxyltransferase domain. The firsocostat-ACC interaction mimics the physiological inhibition of ACC by AMPK.

Summary of Clinical Use Click here for help
GS-0976 has progressed to Phase 2 evaluation in patients with NASH. Its clinical efficacy has been compared to fenofibrate (PPARα agonist, antilipemic drug) and it is also being tested in combination with anti-fibrotic agents and other antilipemic agents.
