Single Ascending Oral Dose Phase I Study With Px-102

A Double-blind, Randomized, Placebo-controlled, Dose-escalation Study of the Safety, Tolerability and Pharmacokinetics of Increasing Single Oral Doses of Px-102 to Healthy Subjects

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.
