Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment: Drugs - TMC435
Treatment: Drugs - Ribavirin (R)
Treatment: Drugs - PegIFNa-2a (P)
Treatment: Drugs - Placebo

Experimental: TMC435 75 mg 12 Wks + PR 24/48 - Participants will receive TMC435 75 mg once daily with PegIFNa-2a (P) once weekly and ribavirin (R) twice daily for 12 weeks followed by Placebo once daily and PR for 12 weeks. Treatment with PR was stopped at Week 24 for participants who met response-guided treatment (RGT) criteria. All other participants continued PR until Week 48.

Experimental: TMC435 75 mg 24 Wks + PR 24/48 - Participants will receive TMC435 75 mg once daily with PegIFNa-2a (P) once weekly and ribavirin (R) twice daily for 24 weeks. Treatment with PR was stopped at Week 24 for participants who met response-guided treatment (RGT) criteria. All other participants continued PR until Week 48.

Experimental: TMC435 150 mg 12 Wks + PR 24/48 - Participants will receive TMC435 150 mg once daily with PegIFNa-2a (P) once weekly and ribavirin (R) twice daily for 12 weeks followed Placebo and PR for 12 weeks. Treatment with PR was stopped at Week 24 for participants who met response-guided treatment (RGT) criteria. All other participants continued PR until Week 48.

Experimental: TMC435 150 mg 24 Wks + PR 24/48 - Participants will receive TMC435 150 mg once daily with PegIFNa-2a (P) and ribavirin (R) for 24 weeks. Treatment with PR was stopped at Week 24 for participants who met response-guided treatment (RGT) criteria. All other participants continued PR until Week 48.

Placebo comparator: Placebo 24 Wks + PR48 - Participants will receive Placebo once daily with PegIFNa-2a (P) and ribavirin (R) for 24 weeks followed by PR until Week 48.


Treatment: Drugs: TMC435

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.
