Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate the effectiveness and safety of TMC435 compared with placebo in participants who are infected with genotype 1 hepatitis C virus who have never received treatment before. Participants will also receive peginterferon alfa-2a or peginterferon alfa-2b and ribavirin as part of their treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a randomized, double-blind (neither physician or participant knows the name of the assigned drug), placebo-controlled study of TMC435 in participants who are infected with genotype 1 hepatitis C virus who have never received treatment for this before. Participants in this study will also receive two other drugs for their infection (either peginterferon alfa-2a (Pegasys®) and ribavirin (Copegus®) or peginterferon alfa-2b (PegIntron®) and ribavirin (Rebetol®). The purpose of the study is to investigate if TMC435 is superior to placebo in reducing hepatitis C virus to an undetectable level 24 weeks after the end of treatment. For the first 12 weeks, participants will take TMC435 or placebo, plus peginterferon and ribavirin. For the next 12 weeks, participants will take peginterferon and ribavirin only. After that, some participants will continue to take peginterferon and ribavirin for up to 24 additional weeks. Other participants will stop taking peginterferon and ribavirin. The study doctor will inform each participant about how to take their study medication and when they should stop taking it. After a participant stops taking study medication, they will continue to come to the doctor's office for study visits until a total of 72 weeks after they enroll in the study. The total duration of the study is 78 weeks (including screening). Participants will be monitored for safety throughout the study. Study assessments at each study visit may include but are not limited to: blood and urine collection for testing, electrocardiogram (ECG) assessments (a measurement of the electrical activity of your heart), participant questionnaires, and physical examinations. TMC435 will be taken as an oral capsule of 150 mg once per day. Peginterferon (Pegasys ®) will be given as an injection of 180 µg once each week. Peginterferon (PegIntron®) will be given as an injection once each week and the dose will depend on your body weight. Ribavirin will be taken as a tablet (Copegus ®) or a capsule (Rebetol ®) twice each day and the dose will depend on your body weight.
