Overview

The purpose of this study is to define and compare the pharmacokinetic (PK) and pharmacodynamic (PD) profile of EYP651 at two dose levels and compare it with Vonafexor Acid PK and PD profile, the Part A.

In addition, Part B of the trial will assess the Drug-Drug Interactions (DDI) potential with the high dose of EYP651.

Description

The two parts are open-label and randomized, with a 2 periods, cross-over design for part A and a 3-period-parallel-arm design for Part B.

Expected duration for part A is approximately 8 weeks and Part B is approximately 12 weeks for each participating subject.
