| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| The primary objective is to evaluate the antiviral efficacy of TMC435 in combination with PegIFNalfa-2a and RBV, with respect to the proportion of subjects with SVR12 (1) in the subjects who participated in the placebo group of a Phase II/III TMC435 study, and (2) in the subjects who participated in a selected Tibotec-sponsored Phase I study. | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
The secondary objectives are:
 1. To evaluate the antiviral efficacy of TMC435 in combination with PegIFNalfa-2a and RBV with
 respect to the proportion of subjects with SVR24.
 - To evaluate the antiviral activity to TMC435 in combination with PegIFNalfa-2a and RBV at all time points, with focus on Week 4, Week 12, Week 24, and Week 48.
 - To evaluate the incidence of on-treatment failure.
 - To evaluate the rate of HCV viral breakthrough during treatment.
 - To evaluate the viral relapse rate after treatment.
 - To determine the proportion of subjects who meet the criteria for treatment completion at Week 24 in the subgroups of subjects who experienced viral relapse or viral breakthrough in a Phase II/III TMC435 study.
 - To determine the viral NS3/4A sequence of subjects not achieving SVR.
 - To evaluate the safety and tolerability of TMC435 in combination with PegIFNalfa-2a and RBV. |
