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 evaluate effectiveness, safety and pharmacokinetics (Explores what the body does to the medication) of TMC435350 in combination with Peginterferon Alfa-2a and Ribavirin in genotype 1 hepatitis C virus infected Japanese participants who have never received treatment for their hepatitis C infection.

Detailed Description

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

This is a Phase 2, randomized (The study medication is assigned by chance.), 5-arm, open label (All people know the identity of the intervention.), multicentre (study conducted at multiple sites) study. Approximately, 84 participants will be randomized to 5 different arms in a 2:2:1:1:1 ratio. In treatment arms 1 and 2, participants will receive 12 weeks of triple therapy (use of 3 medications) with TMC435 50 or 100 mg once daily plus Peginterferon Alfa-2a and Ribavirin followed by 12 weeks of treatment with Peginterferon Alfa-2a and Ribavirin. In treatment arms 3 and 4, participants will receive 24 weeks of triple therapy with TMC435 50 or 100 mg once daily plus Peginterferon Alfa-2a and Ribavirin. In treatment arm 5 (control group), participants will receive Peginterferon Alfa-2a and Ribavirin for 48 weeks. This study will consist a screening phase of upto 6 weeks, treatment phase of upto 48 weeks and a post treatment follow-up period of 24 weeks. Safety evaluations will include assessment of adverse events, clinical laboratory tests, vital signs, and cardiovascular safety.
