Medical Language ↔ Plain English

Inclusion Criteria: * Adult subjects, age ≥18 years. * NASH histological diagnosis according to the currently accepted definition of both EASL and AASLD, requiring the combined presence of steatosis (any degree ≥ 5%) + lobular inflammation of any degree + liver cell ballooning of any amount, on a liver biopsy performed ≤ 6 months before screening in the study or at screening and confirmed by central reading during the screening period and * SAF Activity score of 3 or 4 (\>2) * SAF Steatosis score ≥ 1 * SAF Fibrosis score \< 4 * Subject agrees to have a liver biopsy performed after 24 weeks of treatment. * Compensated liver disease * No other causes of chronic liver disease (autoimmune, primary biliary cholangitis, Hepatitis B virus (HBV), hepatitis C virus (HCV), Wilson's, α-1-antitrypsin deficiency, hemochromatosis, etc…). * If applicable, have a stable type 2 diabetes, defined as HbA1c ≤ 8.5% and fasting glycemia \<10 mmol/L, no changes in medication in the previous 6 months, and no new symptoms associated with decompensated diabetes in the previous 3 months. * Have a stable weight since the liver biopsy was performed defined by no more than a 5 % loss of initial body weight. * Negative pregnancy test or post-menopausal. Women with childbearing potential (i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile) must be using a highly effective method of contraception (i.e. combined (estrogen and progestogen containing) hormonal/ progestogen-only hormonal contraception associated with inhibition of ovulation, intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomised partner). The contraceptive method will have to be followed for at least one menstruation cycle after the end of the study * Subjects having given her/his written informed consent. Exclusion Criteria: * Evidence of another form of liver disease. * History of sustained excess alcohol ingestion: daily alcohol consumption \> 30 g/day (3 drinks per day) for males and \> 20 g/day (2 drinks per day) for females. * Unstable metabolic condition: Weight change \> 5kg in the last three months, diabetes with poor glycemic control (HbA1c \> 8.5%), introduction of an antidiabetic or of an anti-obesity drug/malabsorptive or restrictive bariatric (weight loss) surgery in the past 6 months prior to screening. * History of gastrointestinal malabsorptive bariatric surgery within less than 5 years or ingestion of drugs known to produce hepatic steatosis including corticosteroids, high-dose estrogens, methotrexate, tetracycline or amiodarone in the previous 6 months. * Significant systemic or major illnesses other than liver disease, including congestive heart failure (class C and D of the American Heart Association , AHA), unstable coronary artery disease, cerebrovascular disease, pulmonary disease, renal failure, organ transplantation, serious psychiatric disease, malignancy that, in the opinion of the investigator, would preclude treatment with IVA337 and/or adequate follow up. * HB antigen \>0, HCV Polymerase chain reaction (PCR) tests \>0 (patients with a history of HCV infection can be included if HCV PCR is negative since more than 3 years), HIV infection. * Pregnancy/lactation or inability to adhere to adequate contraception in women of child-bearing potential. * Active malignancy except cutaneous basocellular carcinoma. * Any other condition which, in the opinion of the investigator would impede competence or compliance or possibly hinder completion of the study. * Body mass index (BMI) \>45 kg/m2. * Type 1 diabetes and type 2 diabetic patient on insulin. * Diabetic ketoacidosis * Fasting Triglycerides \> 300 mg/dL. * Hemostasis disorders or current treatment with anticoagulants. * Contra-indication to liver biopsy. * History of, or current cardiac dysrhythmias and/or a history of cardiovascular disease event, including myocardial infarction, except patients with only well controlled hypertension. Any clinically significant ECG abnormality reported by central ECG reading. * Participation in any other clinical study within the previous 3 months. * Have a known hypersensitivity to any of the ingredients or excipients of the Investigational medicinal product (IMP) * Be possibly dependent on the Investigator or the sponsor (e.g., including, but not limited to, affiliated employee). * Creatine phosphokinase (CPK)\>5 x ULN * Osteopenia or any other well documented Bone disease. Patient without well documented osteopenia treated with vitamin D and/or Calcium based supplements for preventive reasons can be included. (The criteria below are applicable only for patients who will undergo a MRI/LMS in selected centers) * Claustrophobia to a degree that prevents tolerance of MRI scanning procedure. Sedation is permitted at discretion of investigator. * Metallic implant of any sort that prevents MRI examination including, but not limited to: aneurysm clips, metallic foreign body, vascular grafts or cardiac implants, neural stimulator, metallic contraceptive device, tattoo, body piercing that cannot be removed, cochlear implant; or any other contraindication to MRI examination.

Outcomes

Primary Outcomes

SAF Activity Score (SAF-A) Decrease of at Least 2 Points With no Worsening of the CRN Fibrosis Score (CRN-F)

SAF-A is the activity part of the Steatosis Activity Fibrosis \[SAF\] histological score, calculated as the sum of lobular inflamation score and balloning score. No worsening of fibrosis means that the CRN fibrosis score (CRN-F) remains stable or decreases.

Time frame: 24 weeks

Secondary Outcomes

NASH Improvement

NASH improvement is defined as a decrease of at least 2 points in NAS score (sum of CRN Steatosis, Inflammation and Ballooning scores) without worsening of CRN Fibrosis score.

Time frame: 24 weeks

NASH Resolution and no Worsening of Fibrosis

Resolution of NASH is defined as a CRN Inflammation score equal to 0 or 1, and a CRN Ballooning score equal to 0. No worsening of fibrosis means that the CRN fibrosis score remains stable or decreases.

Time frame: 24 weeks

Improvement of Fibrosis by at Least 1 Stage and no Worsening of NASH

Improvement of fibrosis is defined as a decrease of at least one stage in CRN Fibrosis score. No worsening of NASH is defined as no increase of CRN Steatosis score, no increase of CRN Inflammation score ans no increase of CRN Ballooning score.

Time frame: 24 weeks

Activity (SAF-A) Improvement

SAF-A is the activity part of the Steatosis Activity Fibrosis \[SAF\] histological score, calculated as the sum of lobular inflamation score and balloning score. Improvement of SAF-A is defined as a decrease of at least 1 point.

Time frame: 24 weeks

Steatosis (CRN-S) Improvement

Improvement of CRN Steatosis score (CRN-S) is defined as a decrease of at least 1 point.

Time frame: 24 weeks

Lobular Inflammation (CRN-I) Improvement

Improvement of CRN Lobular inflammation score (CRN-I) is defined as a decrease of at least 1 point.

Time frame: 24 weeks

Hepatocyte Balooning (CRN-B) Improvement

Improvement of CRN Ballooning (CRN-B) is defined as a decrease of at least 1 point.

Time frame: 24 weeks

Fibrosis (CRN-F) Improvement

Improvement of CRN Fibrosis score (CRN-F) is defined as a decrease of at least 1 point.

Time frame: 24 weeks

Modified ISHAK Fibrosis (ISHAK-F) Improvement

Improvement of Modified ISHAK Fibrosis (ISHAK-F) is defined as a decrease of at least 1 point.

Time frame: 24 weeks

Absolute Change in ALT
