Detailed Description:

This is an open-label (all the people know the identity of the intervention), single arm (study will be conducted in a single group) clinical study, to evaluate the safety, tolerability and efficacy of TMC435 along with pegylated interferon alpha-2a (PegIFNα-2a) and ribavirin (RBV) triple therapy in adult chronic hepatitis C (CHC) genotype-1 infected patients who are co-infected with human immunodeficiency virus-type 1 (HIV-1). The study consists of 3 phases, screening phase (Week -6), treatment phase, and a follow-up phase (up to 24 weeks). In the treatment phase, patients will be classified based on their experience with previous hepatitis C virus (HCV) treatment as follows: 1) HCV treatment-naive (patients who never received medication for the treatment of HCV); 2) prior HCV relapsers (patients who received at least 24 weeks of a PegIFNα-2a and RBV-based therapy and relapsed within 1 year after the last medication intake); and 3) prior HCV non-responders (can be further classified as, null responders: patients having at least 1 prior documented course of PegIFNα-2a and RBV therapy for at least 12 consecutive weeks; or partial responders: patients having at least 20 consecutive weeks which has not been discontinued due to intolerability to PegIFNα-2a and RBV therapy). All patients will receive TMC435 once daily along with PegIFNα-2a and RBV for 12 weeks. Patients who are continuing treatment only with PegIFNα-2a and RBV will follow until 24 or 48 weeks. Pharmacokinetics will be measured after collection of blood samples. Safety evaluations for adverse events, clinical laboratory tests, electrocardiogram, vital signs, physical examinations, and specific toxicities will be performed throughout the study. The total duration of treatment is approximately of 24 weeks.
