Title: A Phase 3, Randomized, Double-blind, Placebo-controlled Study to Investigate the Efficacy, Safety and Tolerability of TMC435 vs Placebo as Part of a Treatment Regimen Including Peginterferon α-2a and Ribavirin in Treatment-naïve, Genotype 1 Hepatitis Cinfected Subjects
Brief Summary: The purpose of this study is to investigate the effectiveness and safety of TMC435 compared with placebo in participants who are infected with genotype 1 hepatitis C virus who have never received treatment before. Participants will also receive peginterferon alpha-2a and ribavirin as part of their treatment.
