Elafibranor Pharmacokinetic Parameters in Hepatic Impaired Patients

Study Overview
=================
Brief Summary
-----------------
This study is being conducted in order to assess the need for dose adjustment for elafibranor in patients with hepatic impairment. Pharmacokinetic parameters of elafibranor and its active metabolite (GFT1007) will be compared in hepatic impaired patients (mild, moderate and severe according to Child-Pugh categories) versus healthy participants after a single oral administration of elafibranor 120 mg.
