Summary

The purpose of this study to evaluate the efficacy, safety and tolerability of TMC435 in combination with Peginterferon alfa-2a (PegINF alfa-2a) and ribavirin (RBV) in both treatment-naïve and treatment experienced, chronic hepatitis C (HCV) virus, genotype-4 infected patients.

Detailed description

This is an open-label (both participant and investigator know the name of the medication given at a certain moment), single arm Phase III study, with 3 subpopulations: treatment naive, previous HCV relapser and previous HCV non-responders. The study will consist of 3 phases: a screening phase of maximum 6 Weeks, an open-label treatment phase of 24 to 48 Weeks for treatment naive patients and relapsers (response guided treatment) and 48 Weeks for non-responders, followed by a 24 Week follow-up period. The duration of participation in the study for an individual participant will be up to 54 to 78 (including screening). Part Ia: All participants will receive 12 Weeks of triple therapy with TMC435 (150mg once daily \[q.d.\]), PegINF-alfa-2a (180µg per Week) and RBV (1000 to 1200 mg per day, based on weight), followed by 12 Weeks of PegINF-alfa-2a (180µg per Week) and RBV (1000 to 1200 mg per day, based on weight). Part Ib: Participants who will need to continue treatment for another 24 Weeks (non-responders + treatment naive and relapser patients who need to continue treatment according to the response guided treatment criteria) will receive an additional 24 Weeks of PegINF-alfa 2a (180 mg per Week) and RBV (1000 to 1200 mg per day, based on weight). Part II: 24 Week follow-up period for all participants, starting after Week 24 or Week 48. In Part Ia, participants will have to come for 6 visits during the first month, followed by a visit once every month until Week 24 (in total 11 visits- Day1, day 3, Day 7, Day 14, day 28, Week 8, Week 12, Week 16, Week 20 and Week 24) at which safety, efficacy and tolerability will be checked. In Part Ib, participants will have to come for 4 additional visits (Week 28, Week 36, Week 42 and Week 48) at which safety, tolerability and efficacy will be checked In the follow-up period, participants will have to come for an additional 3 visits (either Week 28, Week 36 and Week 28 or Week 52, Week 60 and Week 72) at which safety and efficacy will be checked. Participants who withdraw prematurely will have a visit at withdrawal, 4 Weeks after withdrawal and then every 12 Weeks until 72 Weeks after baseline at which safety will be checked.
