Abstract

Background

Pemafibrate is a novel, selective peroxisome proliferator-activated receptor α modulator (SPPARMα). In mice, Pemafibrate improved the histological features of non-alcoholic steatohepatitis (NASH). In patients with dyslipidaemia, it improved serum alanine aminotransferase (ALT).

Aims

To evaluate the efficacy and safety of Pemafibrate in patients with high-risk, non-alcoholic fatty liver disease (NAFLD).

Methods

This double-blind, placebo-controlled, randomised multicentre, phase 2 trial randomised 118 patients (1:1) to either 0.2 mg Pemafibrate or placebo, orally, twice daily for 72 weeks. The key inclusion criteria included liver fat content of ≥10% by magnetic resonance imaging-estimated proton density fat fraction (MRI-PDFF); liver stiffness of ≥2.5 kPa, by magnetic resonance elastography (MRE); and elevated ALT levels. The primary endpoint was the percentage change in MRI-PDFF from baseline to week 24. The secondary endpoints included MRE-based liver stiffness, ALT, serum liver fibrosis markers and lipid parameters.

Results

There was no significant difference between the groups in the primary endpoint (-5.3% vs -4.2%; treatment difference -1.0%, P = 0.85). However, MRE-based liver stiffness significantly decreased compared to placebo at week 48 (treatment difference -5.7%, P = 0.036), and was maintained at week 72 (treatment difference -6.2%, P = 0.024), with significant reduction in ALT and LDL-C. Adverse events were comparable between the treatment groups and therapy was well tolerated.

Conclusions

Pemafibrate did not decrease liver fat content but had significant reduction in MRE-based liver stiffness. Pemafibrate may be a promising therapeutic agent for NAFLD/NASH, and also be a candidate for combination therapy with agents that reduce liver fat content. ClinicalTrials.gov, number: NCT03350165.
