Cilofexor (also known as GS-9674) is a nonsteroidal farnesoid X receptor (FXR) agonist in clinical trials for the treatment of non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH),^[1][2][3] and primary sclerosing cholangitis (PSC).^[4][5] It is being investigated for use alone or in combination with firsocostat, selonsertib,^[1] or semaglutide.^[2][6] In rat models^[3] and human clinical trials^[7] of NASH it has been shown to reduce fibrosis and steatosis, and in human clinical trials of PSC it improved cholestasis and reduced markers of liver injury.^[4]

It is being developed by the pharmaceutical company Gilead Sciences.^[8][6]
