We previously found that a combination of the farnesoid X receptor agonist cilofexor (CILO) and the acetyl-CoA carboxylase inhibitor rsocostat (FIR) improved liver histology and biomarkers in NASH with advanced brosis but was associated with hypertriglyceridemia. We evaluated the safety and efcacy of icosapent ethyl (Vascepa) and fenobrate to mitigate triglyceride elevations in patients with NASH treated with CILO and FIR. METHODS: Patients with NASH with elevated triglycerides (150 and <500 mg/dL) were randomized to Vascepa 2 g twice daily (n [ 33) or fenobrate 145 mg daily (n [ 33) for 2 weeks, followed by the addition of CILO 30 mg and FIR 20 mg daily for 6 weeks. Safety, lipids, and liver biochemistry were monitored. RESULTS: All treatments were well-tolerated; most treatment-emergent adverse events were Grade 1 to 2 severity, and there were no discontinuations due to adverse events. At baseline, median (interquartile range [IQR]) triglycerides were similar in the Vascepa and fenobrate groups (median, 177 [IQR, 154205] vs 190 [IQR, 144258] mg/dL, respectively). Median changes from baseline in triglycerides for Vascepa vs fenobrate after 2 weeks of pretreatment were L12 mg/dL (IQR, L33 to 7 mg/dL; P [ .09) vs L32 mg/dL (IQR, L76 to 6 mg/dL; P [ .010) and at 6 weeks were D41 mg/dL (IQR, 16103 mg/dL; P < .001) vs L2 mg/dL (IQR, L42 to 54 mg/dL; P [ .92). In patients with baseline triglycerides <250 mg/dL, fenobrate was more effective vs Vascepa in mitigating triglyceride increases after 6 weeks of combination treatment (D6 vs D39 mg/dL); similar trends were observed in patients with baseline triglycerides 250 mg/ d(L61 vs D99 mg/dL). CONCLUSIONS: In patients with NASH with hypertriglyceridemia treated with CILO and FIR, fenobrate was safe and effectively mitigated increases in triglycerides associated with acetyl-CoA carboxylase inhibition.

N onalcoholic steatohepatitis (NASH) Q5 is a leading cause of end-stage liver disease and liver trans- plantation in the United States. 1,2 The pathogenesis of NASH is multifactorial and includes contributions from metabolic and other pro-inammatory insults that contribute to the development of brosis and disease progression. 3,4 Targeting multiple relevant pathogenic mechanisms through a combination treatment approach may, therefore, provide optimal efcacy in NASH, partic- ularly among patients with advanced brosis. 46 In the recent phase II ATLAS study, treatment with a combina- tion of the farnesoid X receptor (FXR) agonist cilofexor Abbreviations used in this paper: ACC, acetyl-coenzyme A carboxylase; AE, adverse event; ALP, alkaline phosphatase; ALT, alanine aminotrans- ferase; ANGPTL4, angiopoietin-like 4; AST, aspartate aminotransferase; CILO, cilofexor; FABP1, fatty acid binding protein 1; FAP, broblast acti- vation protein; FGF21, broblast growth factor 21; FIR, rsocostat; FXR, farnesoid X receptor; IQR, interquartile range; GGT, g-glutamyl trans- ferase; LDL, low-density lipoprotein; NASH, nonalcoholic steatohepatitis; PPAR, peroxisome proliferator-activated receptor; SREBP-1c, sterol regulatory element-binding transcription factor 1c; VLDL, very low-density lipoprotein. © 2022 by the AGA Institute.
