A Study to Assess ARI-3037MO on Hepatic Fat Metabolism in Patients With Dysglycemia and Evidence of Hepatic Steatosis

Primary objective To investigate the effect of a 24-week, twice daily dosing regimen of ARI-3037MO compared to placebo on plasma triglyceride (TG) levels, liver enzymes and hepatic fat content in patients with dysglycemia and hepatic steatosis due to nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH). Secondary Objective To investigate the safety and tolerability of a 24-week, twice daily dosing regimen of ARI-3037MO compared to placebo in patients with dysglycemia and evidence of NAFLD or NASH.

This randomized,double-blind, placebo-controlled study will enroll 36 men and women with a diagnosis of NAFLD orNASH. The study will be conducted over a period of approximately 28 wks and will include:a Screening Phase (Days -14to -1); a 24-week long Treatment Phase, during which patients will be randomly assigned to receive ARI-3037MO or placebo; an End-of-study Visit (ESV) scheduled 2 wks after the end of the Treatment Phase The Screening Phase will include 2 visits. Visit 1:There will be an initial assessment of a patient's eligibility for participation in the study. A complete medical history will be obtained and prospective study patients will undergo physical examinations and laboratory evaluations. For patients who have had a liver biopsy in the 6months prior to Visit 1, the histology findings, i.e., NAS, steatosis score and fibrosis score will be recorded. Visit 2:Approximately 1 week after Visit 1, and after the results of clinical laboratory screening test results have been reviewed by the Principal Investigator (PI), patients will be contacted to advise them of their eligibility to continue in the study. Eligible patients will undergo liver magnetic resonance imaging (MRI) to assess intrahepatic fat content. Treatment Phase Patients with MRI results showing intrahepatic fat content of ≥10% will be entered into the Treatment Phase of the study. The Treatment Phase will include 4 outpatient visits over a period of 24 weeks. Visit 3:Patients will be randomly assigned to receive ARI-3037MO or placebo on Day 1 of a 24-week long outpatient treatment period. Baseline assessments, including FibroTest®, FibroScan® and clinical laboratory tests, will be performed, and patients will take study drug twice daily. Visits 4, 5 and 6: During the Treatment Phase, patients will visit the study clinic at 4, 12 and 24 weeks (± 4 days) after Day 1 for evaluations and examinations and to collect study drug. Twenty-four weeks after the start of dosing, at the end of the Treatment Phase, patients will undergo a follow-up MRI and FibroScan† to assess change from baseline in intrahepatic fat content and liver fibrosis, respectively.

†If FibroScan equipment is available at the study site End-of-Study Visit Visit 7:An ESV will occur 2 weeks (± 4 days) after the end of the Treatment Phase.
