About this study
Official title: 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.
Read the 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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).
Measured: Week 36 or 60
Secondary outcomes (8)

The table below shows the percentage of participants with a SVR24 defined as participants with undetectable plasma Hepatitis C Virus Ribonucleic Acid (HCV RNA) at the end of treatment (Week 24 or 48) and at 24 weeks after the last dose of treatment (Week 48 or 72).
Measured: Week 48 or 60

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing TMC435, Pegylated interferon (pegIFN alpha-2a) and Ribavirin (RBV) in people with Hepatitis C, Chronic, run by Janssen Pharmaceutical K.K. at 10 sites in Japan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 4 Feb 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The Percentage of Participants With a Sustained Virologic Response 12 Weeks After the Actual End of Treatment (SVR12) (time frame: Week 36 or 60). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2014.
