Safety Pilot Study of Farnesoid X Receptor (FXR) Agonist in Non-alcoholic Fatty Liver Disease (NAFLD) Patients

The primary aim of the study is to evaluate the safety and tolerability of Px-104 in NAFLD patients and to assess the influence of Px-104 on hepatic fat.

* History or other evidence of decompensated liver disease (Child-Pugh Grade B or higher), coagulopathy, hyperbilirubinemia, hepatic encephalopathy, hypoalbuminemia, ascites, hepatic encephalopathy, and bleeding from esophageal varices are conditions consistent with decompensated liver disease.

* History of any structural cardiac disease.
* In addition, patients with documented or presumed unstable coronary artery disease, stable or unstable cardiovascular disease or cerebrovascular disease.
* One or more of the following conditions: (1) poorly controlled hypertension, OR (2) screening or baseline blood pressure ≥ 160 mmHg for systolic OR (3) screening or baseline blood pressure ≥ 100 mmHg for diastolic blood pressure.

* History of having received any investigational drug ≤ 3 months and/or 6 x half-life prior to the first dose of study drug or the expectation that such drugs will be used during the study. Patients enrolled in this study cannot be enrolled in another study for either research, diagnostic or treatment purposes.
* Woman with childbearing potential unless using adequate contraception (see inclusion criteria); females who are pregnant or breast feeding.
