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

Prescreening Criteria:
Inclusion Criteria:
Upon central biopsy reading process: diagnosis of NASH according to the Steatosis-Activity-Fibrosis (SAF):

General safety:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Ran from Aug 2021 to primary completion in Sep 2026, 61 months.
Of 34 phase 3 interventional studies under Non-alcoholic Fatty Liver Disease, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 61. This study's 61 months is above that.
Primary completion moved once since we started tracking on Sep 25, 2026: Sep 2027 → Sep 2026, on Nov 2, 2026.
