About

This Phase 3 study is conducted to evaluate lanifibranor in adults with NASH and liver fibrosis histological stage F2 or F3

Full description

Primary objectives

This Phase 3 study is conducted to evaluate lanifibranor in adults with NASH and liver fibrosis stage F2 or F3 and consists of 2 sequential parts - an initial double-blind placebo-controlled (DBPC) period (Part A) followed by a double-blind active treatment extension (ATE) period (Part B), with the following primary objectives:

Part A To assess the safety and efficacy of lanifibranor compared to placebo on 'NASH resolution and improvement of fibrosis' assessed by liver histology.

Part B To assess the safety of lanifibranor beyond the DBPC period. Secondary objectives

Key secondary objectives of Part 1:

• To assess the effect of lanifibranor compared to placebo on NASH resolution and no worsening of fibrosis
• To assess the effect of lanifibranor compared to placebo on improvement of fibrosis with no worsening of NASH

Other secondary objectives of both Part 1 and Part 2:

• To assess the effect of lanifibranor on other key histological features of NASH (only for DBPC period)
• To assess the effect of lanifibranor on NASH resolution and improvement of fibrosis in diabetic patients (only for DBPC period)
• To assess the effect of lanifibranor on liver tests
• To assess the effect of lanifibranor on glycaemic parameters
• To assess the effect of lanifibranor on lipid parameters
• To assess the effect of lanifibranor on liver stiffness and steatosis assessed by elastography.
• To assess the effect of lanifibranor on health-related quality of life
• To assess the safety of lanifibranor
• To assess population PK modeling through plasma levels of lanifibranor using sparse sampling scheme (only for DBPC period)

Enrollment: 1,000 estimated patients

Sex: All

Ages: 18+ years old

2. Upon central biopsy reading process: diagnosis of NASH according to the Steatosis-Activity-Fibrosis (SAF):

   1. Steatosis score ≥1
   2. Activity score: A3 or A4
   3. Fibrosis score: F2 or F3

3. No qualitative change in dose for the drugs listed below:

   1. Antidiabetic treatment if glucagon-like peptide-1 receptor agonists (GLP1 receptor agonists) or sodium-glucose co-transporter-2 inhibitors (SGLT2 inhibitors): for at least 3 months
   2. Vitamin E (if at a dose ≥400 IU/day): for at least 6 months
   3. Statins: for at least 3 months

4. No qualitative change in dose for all other chronically administered drugs for at least 3 months prior to Screening

5. Weight stable for 6 months prior to Screening and between the qualifying liver biopsy and Baseline (no more than 5% change for both periods)

6. Negative serum pregnancy test at study Screening for females of childbearing potential confirmed by central laboratory. Females of childbearing potential must practice a consistent and proper use of highly effective method of contraception throughout the study and for 1 month after treatment discontinuation.

Exclusion Criteria:

Liver-related:

5. Positive human immunodeficiency virus (HIV) serology

6. ALT or AST >5 × ULN

7. AST<0.6 ULN if the liver biopsy has to be performed in the scope of the study

8. Abnormal synthetic liver function as defined by Screening central laboratory evaluation

9. Haemoglobin <110 g/L (11 g/dL) for females and <120 g/L (12 g/dL) for males

10. Patient currently receiving any approved treatment for NASH or obesity

11. Current or recent history (<5 years) of significant alcohol consumption

12. Treatment with drugs that may cause non-alcoholic fatty liver disease (NAFLD) administered for at least 2 weeks within 12 months prior to qualifying liver biopsy

    Glycaemia related:

13. HbA1c >9% at Screening

14. Diabetes mellitus other than type 2

15. Current treatment with insulin

16. Treatment with PPAR-gamma agonists (thiazolidinediones [TZDs]) 12 months before screening or historical biopsy.

    Obesity related:

17. Bariatric surgery: Restrictive procedures are allowed, if performed >6 months prior to the qualifying liver biopsy; malabsorptive procedures and procedures combining both restrictive and malabsorptive methods are not allowed within 5 years of the qualifying liver biopsy.

    Cardiovascular related:

18. History of heart failure with reduced left ventricular ejection fraction (LVEF)

19. Atrial fibrillation requiring anticoagulation

20. Unstable heart failure

21. Uncontrolled hypertension at Screening (values >160/100 mm Hg)

    General safety:

22. Women currently breastfeeding

23. Previous exposure to lanifibranor

24. Participation in any clinical trial investigational medicinal product/device within 3 months from Screening or 5 half-lives from Screening, whichever is longer
