Assessment of the Safety and Effect of SAR425899 Versus Placebo for the Treatment of Non-alcoholic Fatty Liver Disease (Restore)

A 52-week Double-blind, Randomized, Placebo-controlled, Phase 2 Study to Assess the Efficacy and Safety of SAR425899 for the Treatment of Non-alcoholic Steatohepatitis (NASH)

Primary Objective:

- To evaluate the dose response relationship of SAR425899 compared to placebo on resolution of non-alcoholic steatohepatitis (NASH) with no worsening of fibrosis in diabetic and non-diabetic patients with histopathologically-confirmed NASH.

Secondary Objectives:

• To assess the effect of SAR425899 on overall non-alcoholic fatty liver disease (NAFLD) activity score (NAS), individual components of NAS (steatosis, hepatocyte ballooning, and lobular inflammation), and fibrosis score.
• To assess to the effect of SAR425899 on MRI-PDFF (Magnetic Resonance Imaging-determined Proton Density Fat Fraction) derived parameters (total liver fat, liver volume, and fractional liver fat content).
• To assess the effect of SAR425889 on body weight and waist/hip circumference ratio.
• To assess SAR425899 pharmacokinetics.
• To assess safety and tolerability of SAR425899.

• Male subjects, whose partners are able to become pregnant, who do not accept to use a condom during sexual intercourse from study inclusion up to 3 months after last dosing; or who are planning to donate sperm from study inclusion up to 3 months after last dosing.
• Patients with coronary, carotid, or peripheral artery revascularization procedures planned during the screening or treatment phases of the protocol.
• Patients with unstable heart conditions.
