Study Description

Brief Summary:

The primary objectives of this study are to evaluate the effect of Elafibranor treatment compared to placebo on 1) histological improvement and 2) all-cause mortality and liver-related outcomes in patients with nonalcoholic steatohepatitis (NASH) and fibrosis.

Outcome Measures

Primary Outcome Measures :

1. Proportion of Elafibranor treated patients relative to placebo achieving resolution of NASH without worsening of fibrosis [ Time Frame: Measurement at 72 weeks ]
   To evaluate the effect of Elafibranor compared to placebo on liver histology in nonalcoholic steatohepatitis (NASH) subjects with fibrosis by assessing the following endpoint: The proportion of Elafibranor treated patients relative to placebo achieving NASH resolution without worsening of fibrosis.
2. Composite long-term outcome composed of all-cause mortality, cirrhosis, and liver-related clinical outcomes [ Time Frame: Time to accrue a pre-specified number of adjudicated events, estimated to be 4 years ]
   To evaluate the effect of Elafibranor compared to placebo on composite long-term outcome measured by the number of patients with the onset of any of the adjudicated events, composed of cirrhosis, all-cause mortality, liver-related clinical outcomes.

Secondary Outcome Measures :

1. Proportion of Elafibranor treated patients relative to placebo achieving improvement of fibrosis [ Time Frame: Measurements at 72 weeks ]
   To evaluate the effect of Elafibranor compared to placebo on liver histology in nonalcoholic steatohepatitis (NASH) subjects by assessing the following endpoint: The proportion of Elafibranor treated patients relative to placebo achieving improvement of liver fibrosis of at least one stage.
2. Proportion of Elafibranor treated patients relative to placebo achieving improvement in histological scores in NASH [ Time Frame: Measurements after 72 weeks of treatment and up to study completion estimated at 4 years of treatment ]
   • Percentage of patients with resolution of NASH without worsening of fibrosis (study completion)
   • Percentage of patients with improvement of fibrosis of at least 1 stage
   • Percentage of patients with at least 1 point improvement in histological scores in NASH
3. Proportion of Elafibranor treated patients relative to placebo with improvement in cardiometabolic and liver markers and liver markers [ Time Frame: Measurements at Week 72, and at the end of the Long-term Treatment Period estimated at 4 years ]

   To assess the following endpoints in Elafibranor treated patients relative to placebo, at Week 72 and at the end of the Long-term Treatment Period, estimated at 4 years:

   • cardiovascular events
   • changes in liver enzymes and liver markers
   • changes in non-invasive markers of fibrosis and steatosis
   • changes in lipid parameters
   • variation in body weight
   • changes in insulin resistance and glucose homeostasis markers
   • changes in inflammatory markers
   • changes in quality of life (36-Item Short-Form Health Survey [SF-36]) questionnaire)
4. Proportion of Elafibranor treated patients relative to placebo having a liver-related death [ Time Frame: Measurements at Week 72, and at the end of the Long-term Treatment Period estimated at 4 years ]

   To assess the following endpoints in Elafibranor treated patients relative to placebo, at Week 72 and at the end of the Long-term Treatment Period, estimated at 4 years:

   o liver-related death
