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 alfa-2a or peginterferon alfa-2b and ribavirin as part of their treatment.

Eligibility Criteria

Inclusion Criteria

  • Genotype 1 hepatitis C infection (confirmed at screening)
  • Participant has not received any prior treatment for hepatitis C
  • Participant must have had a liver biopsy within 3 years before screening (or between the screening and baseline visit) showing chronic hepatitis C infection
  • Must agree to use 2 forms of effective contraception throughout study (both males and females)

Exclusion Criteria

  • Infection with HIV or non genotype 1 hepatitis C
  • Liver disease not related to hepatitic C infection
  • Hepatic decompensation
  • Significant laboratory abnormalities or other active diseases
  • Pregnant or planning to become pregnant
