A Phase III Study of TMC435 in Genotype 1, Hepatitis C-infected Participants Who Failed to Respond to Previous IFN-based Therapy
A Phase III, Randomized, Open-label, Two-arm Trial in Japan to Investigate the Efficacy and Safety of TMC435 as Part of a Treatment Regimen Including Peginterferon Alfa-2a and Ribavirin in Hepatitis C, Genotype 1-Infected Subjects Who Failed to Respond to Previous IFN-based Therapy

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 failed to respond to previous interferon (IFN)-based therapy in Japan.

Outcome Measures
Primary Outcomes (1)
The Percentage of Participants With a Sustained Virologic Response at the End of Treatment (EOT) and 12 Weeks After the Last Dose of Treatment (SVR12)
The table below shows the observed percentage of participants in each treatment group with a SVR12 defined as undetectable plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels at the EOT (Week 24 or 48) and at 12 weeks after the last dose of treatment (Week 36 or 60).
EOT (Week 24 or 48) and Week 36 or 60
Secondary Outcomes (10)
The Percentage of Participants With a Sustained Virologic Response 24 Weeks After the End of Treatment (EOT) and 24 Weeks After the Last Dose of Treatment (SVR24)
EOT (Week 24 or 48) and Week 48 or 72
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
Day 3, Day 7, and 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 Percentage of Participants With Undetectable Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Levels During Treatment for Participants Who Did Not Achieve Undetectable Plasma HCV RNA Levels at Week 12
Weeks 24, 48, EOT (Weeks 24 or 48), SVR12 (Weeks 36 or 60), and SVR24 (Weeks 48 or 72)
The Number of Participants With Viral Breakthrough During the Study
Up to EOT (Week 24 or 48)

Study Arms (2)
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. Treatment will be stopped at Week 24 if participants achieve plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels \< 1.2 log10 IU/mL detectable or undetectable at Week 4, and undetectable plasma HCV RNA levels at Week 12. All other participants will continue PR until Week 48.
TMC435 100 mg 24 Wks + PR24/48
EXPERIMENTALParticipants will receive TMC435 100 mg once daily with PegIFNα-2a and ribavirin ( PR) for 24 weeks (Wks). Treatment will be stopped at Week 24 if participants achieve plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels \< 1.2 log10 IU/mL detectable or undetectable at Week 4, and undetectable plasma HCV RNA levels at Week 12. All other participants will continue PR until Week 48.
Interventions
100-mg capsule taken by mouth once daily for 12 or 24 weeks.
PegIFNα-2a (PEGASYS) will be administered according to the manufacturer's prescribing information as 180 mcg once weekly injected subcutaneous (under the skin) for up to 24-48 weeks.
RBV (COPEGUS) will be administered according to the manufacturer's prescribing information. If body weight is \> 80 kg the total daily dose of RBV will be 1000 mg, taken by mouth as 400 mg (2 tablets of 200 mg) after breakfast and 600 mg (3 tablets of 200 mg) after supper. If body weight is \> 60 kg to \<=80 kg the total daily dose will be 800 mg, taken by mouth as 400 mg (2 tablets of 200 mg per intake) after breakfast and supper. If body weight is \<=60 kg the total daily dose of RBV will be 600 mg, taken by mouth as 200 mg (1 tablet of 200 mg) after breakfast and 400 mg (2 tablets of 200 mg) after supper. Total duration of RBV will be 24-48 weeks.
