December 16, 2013 updated by: Janssen Pharmaceutical K.K.
A Phase III, Open-label Trial in Japan to Investigate the Efficacy and Safety of TMC435 as Part of a Treatment Regimen Including Peginterferon Alfa-2a and Ribavirin in Genotype 1, Hepatitis C-infected Subjects Who Relapsed After Previous IFN-based Therapy
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.

Detailed Description
This is a single-arm study to evaluate the efficacy and safety of TMC435 in combination with the standard of care (SoC), PegIFNα-2a (P) and ribavirin (R), in adult, genotype 1 HCV-infected participants who relapsed after previous IFN-based therapy in Japan.
The study objective is to evaluate the efficacy of TMC435 by the percentage of participants with undetectable HCV ribonucleic acid (RNA).
Participants will receive 12 weeks of treatment with TMC435 (100 mg) once daily plus PR followed by 12 or 36 weeks of treatment with PR.
TMC435 is a 100-mg capsule and will be taken orally (via the mouth).
Treatment with PR will last 24 or 48 weeks.
Pegylated interferon is supplied as a vial containing 1.0 mL solution with 180 µg PegIFNα-2a and will be injected by a syringe under the skin once weekly.
Ribavirin is given as 200-mg tablets (daily dose: 600-1000 mg), taken orally two times a day after meals.
The participants will receive oral capsules of TMC435 (100 mg) once daily up to Week 12.

Experimental: TMC435 100 mg 12 Wks + PR24/48
Participants 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).
