Clinical Trial Summary

Subjects with biopsy-proven NASH will be randomly assigned in a 2:1 ratio to oral doses of namodenoson 25 mg every 12 hours or matching placebo every 12 hours for 36 weeks. Subjects will be evaluated regularly for safety, and efficacy biomarkers will be measured at Baseline and Weeks 6, 12, 24, and 36. At Week 36, all subjects will undergo liver biopsy.

Description:

This is a multicenter, randomized, double-blind, placebo-controlled study in subjects with a diagnosis of NASH and F1-3 fibrosis. Subjects will undergo Screening procedures during the 6 weeks preceding Baseline. Subjects (n = ~114) will be randomly assigned in a 2:1 ratio to oral doses of namodenoson 25 mg every 12 hours or matching placebo every 12 hours for 36 weeks. Subjects will be evaluated regularly for safety, and efficacy biomarkers will be measured at Baseline and Weeks 6, 12, 24, and 36. At Week 36, all subjects will undergo post-treatment liver biopsy, which will be interpreted by a blinded expert hepatopathologist. Subjects will return for a follow-up visit 6 weeks after completion of the last dose of study drug.

11. Active rheumatoid arthritis treated with small-molecule (including methotrexate) or biologic disease-modifying anti-rheumatic agent concurrently or within 1 year.

12. Use of any immunosuppressive medication, anti-inflammatory monoclonal antibody treatment, or chronic systemic corticosteroids >10 mg prednisone-equivalent concurrently or within 1 year.

13. More than 7 days of treatment with valproic acid, tamoxifen, amiodarone, or anti-cholinergic agents within 3 months.

14. Uncontrolled or clinically unstable thyroid disease.

15. Uncontrolled arterial hypertension or congestive heart failure (New York Heart Association Classification 3 or 4), or other heart disease which is, in the Investigator's judgment, clinically unstable.

16. Angina, myocardial infarction, cerebrovascular accident, coronary/peripheral artery bypass graft surgery, transient ischemic attack, or pulmonary embolism within 3 months.

17. QTcF interval on Screening Visit ECG or an average of triplicate Baseline Visit ECGs > 450 milliseconds (msec) for males or > 470 msec for females.

18. A condition which increases proarrhythmic risk, including hypokalemia, hypomagnesemia, or congenital Long QT Syndrome.

19. Ongoing or planned use of a concomitant medication that is on the CredibleMedsTM list of drugs known to cause Torsades des Pointes.

20. Active gastrointestinal disease which could interfere with the absorption of oral medication.

21. Any severe, acute, or chronic medical or psychiatric condition, or laboratory abnormality that would make the patient inappropriate for entry into this study.
