Safety, Tolerability, Pharmacokinetics and Efficacy of EYP001a in Patients With Nonalcoholic Steatohepatitis (NASH)

A Phase 2a, Randomized, Double-Blind, Multicenter, Placebo-Controlled Study to Assess the Safety, Tolerability, Pharmacokinetics, and Efficacy of EYP001a in Patients With Nonalcoholic Steatohepatitis

The purpose of this study is to assess the effects of EYP001a (Vonafexor) with respect to safety, tolerability, pharmacokinetics and on markers of liver inflammation in patients with NASH

This is a 2-part, randomized, double-blind, multicenter, placebo-controlled study to evaluate the safety and efficacy of Vonafexor in patients with NASH who likely have stage F2 to F3 fibrosis at approximately 50 global clinical sites. Overall, approximately 114 eligible patients will be enrolled: 24 patients in Part A (Safety Run-in Cohort), followed by 90 patients in Part B.

In Part A, 24 patients will be randomized on Day 1 to 1 of 4 parallel treatment groups: 100 mg Vonafexor twice daily (BID), 200 mg Vonafexor once daily (QD), 400 mg Vonafexor QD, or placebo BID. In Part B, 90 patients will be randomized on Day 1 to 1 of 3 parallel treatment groups: 100 mg Vonafexor QD, 200 mg Vonafexor QD, or placebo QD.

Inclusion Criteria:

• Written informed consent
• Suspected diagnosis of NASH, evidenced by elevated alanine aminotransferase (ALT), liver stiffness compatible with F2 or F3 fibrosis and Liver Fat Content (LFC) ≥10% as measured by MRI
• Women of childbearing potential and male patients with female partners must agree to use a dual method of contraception

Exclusion Criteria:

• Evidence of worsening liver injury
• Previous diagnosis of other forms of non-NASH liver disease
• Use of Vitamin E, glitazones, glucagon-like Peptide-1 receptor agonists, ursodeoxycholic acid, or obeticholic acid within 90 days prior to screening
• History of cirrhosis or liver decompensation
• Known history of alcohol abuse or daily heavy alcohol consumption
• Pregnant or breastfeeding women
• Type 1 diabetes mellitus and uncontrolled type 2 diabetes mellitus
• Patients with contraindications to MRI imaging
