12 Week Study of Anti-Viral Effect of Oral UT-231B in Non-cirrhotic Hepatitis C Patients who have Failed Interferon-based Therapy.

Summary

This is a multi-center study. Neither the study subjects nor the physicians will know what treatment an individual subject is receiving. Subjects will be randomly assigned (like flipping a coin) to one of five treatment groups. The treatment groups include four different dosing groups of active study drug and one group of subjects who will receive placebo. A 12 week follow up period occurs after the 12 weeks of dosing. The study endpoint is a reduction in Hepatitis C viral load.
