Eligibility
Key inclusion criteria
* Patient must have had a liver biopsy before screening (or between the screening and baseline visit), unless patient cannot undergo such a procedure or has evidence of portal hypertension not associated with cirrhosis. For patients who had a liver biopsy performed more than 2 years prior to screening or without a biopsy (because of a contraindication or portal hypertension), a non-invasive staging assessment needs to be available. Non-invasive staging assessments include FibroScan, MR-Elastography, or FibroTest/FibroSure and must not be older than 6 months prior to screening
* Chronicity of hepatitis C virus (HCV) infection, as confirmed by one or both of the following: presence of anti-HCV antibody and/or HCV ribonucleic acid (RNA) at least 6 months prior to the screening visit and/or presence of fibrosis on biopsy
* Genotype 1 HCV infection with plasma HCV RNA of >10,000 IU/mL (both confirmed at screening)
* Patient must have had at least 1 documented previous course of treatment with PegINFa-2a or PegINFa-2b in combination with ribavirin (RBV) (at least 12 weeks for null responder and 20 weeks for partial responder)
Minimum age
18 Years
Maximum age
70 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Hepatic decompensation (impaired functioning of the liver), as indicated by significant laboratory abnormalities or other active diseases
* Infection with Human Immunodeficiency Virus (HIV) or non genotype 1 hepatitis C
* Liver disease not related to hepatitis C infection
* Previous chronic hepatitis C treatment, other than PegIFN and RBV

Summary
Brief summary
The purpose of this study is to demonstrate the efficacy of TMC435 in combination with peginterferon (PegIFN) + ribavirin (RBV) by means of establishing its non- inferiority compared to an approved regimen of telaprevir + PegIFN + RBV in patients who have previously failed PegIFN.
