Outcome Measures

Primary Outcome Measures :
  1. Number of Elafibranor-treated Participants Relative to Placebo Achieving Resolution of Nonalcoholic Steatohepatitis 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) participants with fibrosis by assessing the following endpoint: The number of Elafibranor-treated participants relative to placebo achieving NASH resolution without worsening of fibrosis. This outcome measure is for the surrogate endpoint analysis.

  2. Time to Long-term Outcome Composed of All-cause Mortality, Cirrhosis, and Liver-related Clinical Outcomes [ Time Frame: From first randomization up to early termination of the study corresponding to 54 months (54 months being the longest duration for any given participant) ]
    Composite long-term outcome measured by the number of participants with the onset of any of the adjudicated events, composed of death due to any cause, histological liver cirrhosis, and the full list of portal hypertension/cirrhosis related events as follows: liver transplantation; model for end stage liver disease (MELD) score greater than or equal to 15 for participants with baseline score less than or equal to 12, and onset of variceal bleeding requiring hospitalization, hepatic encephalopathy with West Haven/Conn score greater than or equal to 2 and requiring hospitalization, spontaneous bacterial peritonitis, and ascites requiring treatment. The MELD scale ranges from 6 to 40, showing how much a participant needs a liver transplant: higher number is more urgent. The West Haven/Conn scale is 5-point (0 to 4) grading severity of hepatic encephalopathy: higher score means worse hepatic encephalopathy. This outcome measure is for the long-term endpoint analysis.


Secondary Outcome Measures :
  1. Number of Elafibranor-treated Participants Relative to Placebo Achieving Improvement of Fibrosis of at Least 1 Stage [ Time Frame: Measurements at 72 weeks ]
    To evaluate the effect of Elafibranor compared to placebo on liver histology in nonalcoholic steatohepatitis (NASH) participants by assessing the following endpoint: The number of Elafibranor-treated participants relative to placebo achieving improvement of liver fibrosis of at least 1 stage according to NASH Clinical Research Network (CRN) Scoring. As the primary efficacy objective was not met, the secondary efficacy endpoints were not formally tested. This outcome measure is for the surrogate endpoint analysis.

  2. Change From Baseline of Hemoglobin A1c (HbA1c) in Diabetic Participants After 72 Weeks of Treatment in Elafibranor-treated Participants Relative to Placebo [ Time Frame: Measurements after 72 weeks of treatment and up to study termination ]
    Hemoglobin A1c (HbA1c) were tested at Week 72. Changes from baseline in HbA1c at Week 72 were evaluated. As the primary efficacy objective was not met, the secondary efficacy endpoints were not formally tested. This outcome measure is for the surrogate endpoint analysis.

  3. Change From Baseline of High-density Lipoprotein (HDL) Cholesterol After 72 Weeks of Treatment in Elafibranor-treated Participants Relative to Placebo [ Time Frame: Measurements after 72 weeks of treatment and up to study termination ]
    High-density lipoprotein (HDL) cholesterol was tested at Week 72. Changes from baseline in HDL cholesterol were evaluated at Week 72. As the primary efficacy objective was not met, the secondary efficacy endpoints were not formally tested. This outcome measure is for the surrogate endpoint analysis.

  4. Change From Baseline of Low-density Lipoprotein (LDL) Cholesterol After 72 Weeks of Treatment in Elafibranor-treated Participants Relative to Placebo [ Time Frame: Measurements after 72 weeks of treatment and up to study termination ]
    Low-density lipoprotein (LDL) cholesterol was tested at Week 72. Changes from baseline in LDL cholesterol were evaluated at Week 72. As the primary efficacy objective was not met, the secondary efficacy endpoints were not formally tested. This outcome measure is for the surrogate endpoint analysis.

  5. Change From Baseline of Homeostatic Model Assessment-IR (HOMA-IR) After 72 Weeks of Treatment in Elafibranor-treated Participants Relative to Placebo in Non-diabetic Participants [ Time Frame: Measurements after 72 weeks of treatment and up to study termination ]
    Homeostatic model assessment-IR (HOMA-IR) was tested at Week 72. Changes from baseline in HOMA-IR were evaluated at Week 72. As the primary efficacy objective was not met, the secondary efficacy endpoints were not formally tested. This outcome measure is for the surrogate endpoint analysis.

  6. Change From Baseline of Non-high Density Lipoprotein Cholesterol After 72 Weeks of Treatment in Elafibranor-treated Participants Relative to Placebo [ Time Frame: Measurements after 72 weeks of treatment and up to study termination ]
    Non-high density lipoprotein (HDL) cholesterol was tested at Week 72. Changes from baseline in non-HDL cholesterol were evaluated at Week 72. As the primary efficacy objective was not met, the secondary efficacy endpoints were not formally tested. This outcome measure is for the surrogate endpoint analysis.

  7. Change From Baseline of Triglycerides After 72 Weeks of Treatment in Elafibranor-treated Participants Relative to Placebo [ Time Frame: Measurements after 72 weeks of treatment and up to study termination ]
    Triglycerides was tested at Week 72. Changes from baseline in triglycerides were evaluated at Week 72. As the primary efficacy objective was not met, the secondary efficacy endpoints were not formally tested. This outcome measure is for the surrogate endpoint analysis.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Males or females aged from 18 to 75 years inclusive at first screening visit.
  2. Must provide signed written informed consent and agree to comply with the study protocol.

  3. Females participating in this study must be of nonchildbearing potential or using highly efficient contraception for the full duration of the study and for 1 month after the end of treatment, as described below:

    1. Cessation of menses for at least 12 months due to ovarian failure,
    2. Surgical sterilization such as bilateral oopherectomy, hysterectomy, or medically documented ovarian failure
    3. If requested by local IRB regulations and/or National laws, sexual abstinence may be considered adequate (the reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient)
