Title: An Exploratory Phase IIa, Randomized, Open-Label Trial to Investigate the Efficacy and Safety of 12 Weeks or 24 Weeks of TMC435 in Combination With PSI-7977 (GS7977) With Or Without Ribavirin in Chronic Hepatitis C Genotype 1-Infected Prior Null Responders To Peginterferon/Ribavirin Therapy or HCV Treatment-Naive Subjects
Brief Summary: The purpose of this study is to investigate the efficacy and safety of TMC435 plus PSI-7977 (GS7977) with or without ribavirin in patients who are chronically infected with genotype 1 hepatitis C virus (HCV) and who did not respond to prior peginterferon/ribavirin therapy or are HCV treatment-naive (patients who never received treatment for HCV infection).
