BACKGROUND AND AIMS: We evaluated the safety and efficacy of cilofexor (formerly GS-9674), a small-molecule nonsteroidal agonist of farnesoid X receptor, in patients with nonalcoholic steatohepatitis (NASH). APPROACH AND RESULTS: In this double-blind, placebo-controlled, phase 2 trial, 140 patients with noncirrhotic NASH, diagnosed by magnetic resonance imaging-proton density fat fraction (MRI-PDFF) ≥8% and liver stiffness ≥2.5 kPa by magnetic resonance elastography (MRE) or historical liver biopsy, were randomized to receive cilofexor 100 mg (n = 56), 30 mg (n = 56), or placebo (n = 28) orally once daily for 24 weeks. MRI-PDFF, liver stiffness by MRE and transient elastography, and serum markers of fibrosis were measured at baseline and week 24. At baseline, median MRI-PDFF was 16.3% and MRE-stiffness was 3.27 kPa. At week 24, patients receiving cilofexor 100 mg had a median relative decrease in MRI-PDFF of -22.7%, compared with an increase of 1.9% in those receiving placebo (P = 0.003); the 30-mg group had a relative decrease of -1.8% (P = 0.17 vs. placebo). Declines in MRI-PDFF of ≥30% were experienced by 39% of patients receiving cilofexor 100 mg (P = 0.011 vs. placebo), 14% of those receiving cilofexor 30 mg (P = 0.87 vs. placebo), and 13% of those receiving placebo. Serum gamma-glutamyltransferase, C4, and primary bile acids decreased significantly at week 24 in both cilofexor treatment groups, whereas significant changes in Enhanced Liver Fibrosis scores and liver stif...
