Brief Summary
The purpose of this study is to evaluate the efficacy and safety of TMC435 in combination with peginterferon alfa-2a (PegIFNα-2a) and ribavirin in genotype 1 hepatitis C virus (HCV)-infected participants who relapsed after previous interferon (IFN)-based therapy in Japan.

Outcome Measures
Primary Outcomes (1)
The Percentage of Participants With a Sustained Virologic Response 12 Weeks After the Actual End of Treatment (SVR12)
The table below shows the percentage of participants with an SVR12 defined as participants with undetectable plasma Hepatitis C Virus Ribonucleic Acid (HCV RNA) at the end of treatment (Week 24 or 48) who also had undetectable plasma Hepatitis C Virus Ribonucleic Acid (HCV RNA) 12 weeks after the last dose of treatment (Week 36 or 60).
Week 36 or 60
Secondary Outcomes (8)
The Percentage of Participants With a Sustained Virologic Response 24 Weeks After the Actual End of Treatment (SVR24)
Week 48 or 60
The Percentage of Participants Who Achieved a Greater Than or Equal to 2 log10 IU/mL Drop From Baseline in Plasma Hepatitis C Virus Ribonucleic Acid (HCV RNA) at Each Time Point During Treatment and Follow-up
Days 3 and 7, Weeks 2, 3, 4, 8, 12, 16, 20, 24, 28, 36, 48, 60, 72, EOT, and follow-up (FU) Weeks 4, 12, and 24
The Percentage of Participants With Undetectable Plasma Hepatitis C Virus Ribonucleic Acid (HCV RNA) During Treatment and at the End of Treatment (EOT)
Weeks 4, 12, 24, 36, 48, 60, 72, and at EOT
The Number of Participants With Viral Breakthrough
Day 1 until end of treatment (EOT [Week 24 or 48])
The Number of Participants Demonstrating Viral Relapse
Up to 72 weeks

Study Arms (1)
TMC435 100 mg 12 Wks + PR24/48
EXPERIMENTALParticipants will receive TMC435 100 mg once daily with PegIFNα-2a and ribavirin (PR) for 12 weeks (Wks) followed by PR until Week 24 (PR 24). Treatment will be stopped at Week 24 in participants who achieve plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels less than (\<) 1.2 log10 IU/mL detectable or undetectable of at Week 4, and undetectable HCV RNA levels at Week 12. All other participants will continue PR until Week 48 (PR 48).
Interventions
180 mcg injected subcutaneously (by a syringe under the skin) once weekly for 12 to 36 weeks (or until Week 48).
200-mg tablets (daily dose: 600-1000 mg) taken orally (by mouth) two times a day for 12 to 36 weeks (or until Week 48).
Eligibility Criteria
You may qualify if:
- Participants must have chronic genotype 1 HCV with HCV RNA level \>= 5.0 log10 IU/mL
- Participant relapsed after previous IFN-based therapy
- Participant must be willing to use contraceptive measures from the time of informed consent to 6 months after last dose of study medication.
You may not qualify if:
- Co-infection with any other HCV genotype or co-infection with the human immunodeficiency virus (HIV)
- Diagnosed with hepatic cirrhosis or hepatic failure
- A medical condition which is a contraindication to pegIFN or ribavirin therapy
- History of, or any current medical condition, which could impact the safety of the patient in the study
