Summary
Brief summary
The purpose of this study is to evaluate the efficacy of 4 different regimens of TMC435 in
combination with peginterferon alfa-2a (PegIFNa-2a) and ribavirin (RBV), defined as the
proportion of patients with sustained virologic response at Week 72 (patients with
undetectable plasma HCV RNA [less than 25 IU per mL undetectable] at the end of treatment and
at Week 72), compared to the control group receiving PegIFN and RBV in combination with
TMC435-matched placebo.
