Elafibranor, PK and Safety in Children and Adolescents 8 to 17 Years of Age With Non Alcoholic Steatohepatitis (NASH)

An Open Label, Randomized, Multicenter Study to Assess the Pharmacokinetic and Pharmacodynamic Profile and the Safety and Tolerability of Two Dose Levels of Elafibranor (80 mg and 120 mg) in Children and Adolescents, 8 to 17 Years of Age, With Nonalcoholic Steatohepatitis (NASH)

The study was being conducted in order to assess the pharmacokinetics and the safety of elafibranor following once daily administration of two dose levels of elafibranor (80 milligrams [mg] and 120mg) during 3 months in children and adolescent population (8 to 17 years of age) with non alcoholic steatohepatitis (NASH).

Inclusion Criteria:

• Was male or female between 8 and 17 years of age (inclusive) at the time of Screening Visit (when consent for study participation is given) and at the time of Randomization;
• Diagnosis of NASH confirmed by histological evaluation (with or without fibrosis) from a liver biopsy obtained within 24 months prior to Randomization;
• Had an alanine aminotransferase (ALT) level greater than (>) 50 international units per liter (IU/L), at Screening;
• Had a Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) greater than or equal to (>=) 5, at Screening;
• Had a Body Mass Index z-score (BMI z-score) (also referred to as BMI-for-age percentile) >=85th percentile for age and gender at Screening;
• Had a Hemoglobin A1C (HbA1c) less than or equal (<=) to 8.5%. If the participants had Type 2 diabetes and is taking anti-diabetic therapy (e.g., metformin or insulin), treatment must had been started at least 3 months prior to Screening and the dose must had been stable for at least 3 months prior to Screening and should remain stable through Randomization;
• Sexually active female participants of childbearing potential must had agree to utilize a highly effective method of contraception per the Clinical Trial Facilitation Group Guidelines from Screening through 30 days after the last dose of study drug (1 month after the end of treatment), and agree to monthly pregnancy testing during the study up to and including end of study.
