Sperimentale: TMC435 100 mg 12 Wks + PR24/48
Participants will receive TMC435 100 mg once daily with PegIFNα-2a and ribavirin (PR) for 12 weeks (Wks) followed by PR until Week 24 (PR 24).
Treatment will be stopped at Week 24 in participants who achieve plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels less than (<) 1.2 log10 IU/mL detectable or undetectable of at Week 4, and undetectable HCV RNA levels at Week 12.
All other participants will continue PR until Week 48 (PR 48).

100-mg capsule once daily for 12 weeks
180 mcg injected subcutaneously (by a syringe under the skin) once weekly for 12 to 36 weeks (or until Week 48).
Altri nomi:

|
Viral breakthrough was defined as a confirmed increase of greater than 1 log10 IU/mL in plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels from the lowest level reached or a confirmed value of plasma HCV RNA of > 2.0 log10 IU/mL in particpants whose plasma HCV RNA level had previously been below 1.2 log10 IU/mL detectable or undetectable during the treatment period.
The table below shows that no viral breakthrough was noted in any participants during the treatment period of the study.
