For male participants, contraceptive measures must be taken during the study, either by the male participant or his female partner. 4. Aged from 18 to 75 years inclusive at screening. 5. BMI ≤ 45 kg/m². 6. Patients agree to have one liver biopsy during the screening period for diagnostic purpose (if no historical biopsy within 6 months before randomization is available) and one at the end of the treatment period for assessment of the treatment effects. 7. For hypertensive patients, hypertension must be controlled by stable dose of anti-hypertensive medication for at least 2 months prior to screening (and the stable dose can be maintained throughout the study). 8.

Histological confirmation of steatohepatitis on a diagnostic liver biopsy (biopsy obtained within 6 months prior to randomization or during the screening period). Histological diagnostic is confirmed by central reading of the slides (steatosis > 5% + lobular inflammation, any grade + ballooning, any amount). 10. For patients with Type 2 Diabetes, glycemia must be controlled (HbA1c≤8.5%). If glycemia is controlled by anti-diabetic drugs, qualitative change (i.e. implementation of a new antidiabetic drug) is not permitted within 6 months prior to randomization and should be avoided during the study. Treatments with metformin, DPPIV inhibitors, GLP1 agonists, sulfamides, insulin are authorised. Sulfamides and insulin are permitted if glycemia is self-monitored by the patient. 11. Patients agree to come to the study visits within the protocol-specified delay. |

Primary objective is to evaluate the efficacy of GFT505 80mg and GFT505 120mg once daily for 52 weeks versus placebo in reversing histological steatohepatitis without worsening of fibrosis.
