Background And Aims:
Metabolic dysfunction-associated steatotic liver disease (MASLD) can progress to severe forms such as metabolic dysfunction-associated steatohepatitis (MASH). Effective treatments for MASH are urgently needed. This study aimed to evaluate the efficacy and safety of chiglitazar, a PPAR pan-agonist, in MASLD with hypertriglyceridemia and insulin resistance.
Approach And Results:
In this phase II multicenter, randomized, double-blind and placebo-controlled study, 104 patients with MASLD with hypertriglyceridemia and insulin resistance were randomized 2:2:1 to receive 48 mg, 64 mg of chiglitazar, or placebo once daily for 18 weeks. The primary endpoint was the percentage change in liver fat content measured by magnetic resonance imaging proton density fat fraction (MRI-PDFF) at week 18. Chiglitazar significantly reduced liver fat content, with percentage change from baseline at week 18 of -28.1% (95% CI -37.5 to -18.7) in the 48 mg group and -39.5% (95% CI -49.0 to -30.0) in the 64 mg group, compared with -3.2% (95% CI -16.8 to 10.4) in placebo group. The differences compared with placebo were -24.9% ( p <0.05) for the 48 mg group and -36.3% ( p <0.001) for the 64 mg group. Chiglitazar also significantly improved liver injury-related biomarkers such as ALT, AST, and γ-GT. Liver fibrosis indicators, lipid parameters, insulin resistance, and metabolic syndrome showed an improved trend. Both doses of chiglitazar were well tolerated, with most adverse events being mild to moderate.
Conclusions:
Chiglitazar significantly reduced liver fat content in MASLD with hypertriglyceridemia and insulin resistance, with a dose-dependent effect and a favorable safety profile.
