The purpose of this study is to assess the safety and tolerability of the FXR agonist Px-102 in healthy subjects after single oral dosing.

The study is a single-centre, double-blind, randomized, placebo-controlled, parallel group phase I study with healthy male subjects receiving ascending single oral oral doses of Px-102 to assess the safety and tolerability, pharmacokinetics and pharmacodynamics.

Inclusion Criteria:

• Healthy male subject of caucasian origin 18 to 45 years of age
• Good state of health (mentally and physically) as determined by medical history, physical examination, vital signs, ECG recording and clinical lab results.
• BMI in between 20-29 kg/m² with absolute weight in between 70-120 kg.
• Serum triglyceride, total cholesterol and liver enzyme levels (alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), alkaline phosphatase (AP)) strictly within the normal ranges at screening and on Day -1.
• HbA1c ≤ 6.5 %
