The purpose of this study is to evaluate the safety and tolerability of TMC435 along with pegylated interferon alpha-2a (PegIFNα-2a) and ribavirin (RBV) triple therapy in hepatitis C virus genotype-1 infected subjects, co-infected with human immunodeficiency virus-type 1, and to evaluate the number of patients with sustained virologic response (SVR) at 12 weeks after the planned end of treatment.
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.

Percentage of Participants With Sustained Virologic Response at Week 12 (SVR 12)
The SVR 12 was defined as hepatitis C virus (HCV) ribonucleic acid (RNA) levels less than (\<) 25 international unit per milliliter (IU/mL) undetectable at the actual end of treatment (EOT), and HCV RNA levels \<25 IU/mL undetectable or HCV RNA levels \<25 IU/mL detectable at 12 Weeks after end of treatment.
Time frame: 12 weeks after end of treatment (Week 24 or 48)
Percentage of Participants With Sustained Virologic Response at Week 24 (SVR 24)
The SVR 24 was defined as hepatitis C virus (HCV) ribonucleic acid (RNA) levels less than (\<) 25 international unit per milliliter (IU/mL) undetectable at the actual end of treatment (EOT), and HCV RNA levels \<25 IU/mL undetectable or HCV RNA levels \<25 IU/mL detectable at 24 weeks after end of treatment.
Time frame: 24 weeks after end of treatment (Week 24 or 48)
Percentage of Participants With Hepatitis C Virus Ribonucleic Acid (HCV-RNA) Less Than (<) 25 International Units (IU/mL) Undetectable or Detectable/Undetectable
Percentage of participants with HCV RNA less than (\<) 25 IU/mL undetectable (undet.) or detectable (det.)/undetectable at specific time points were observed.
Time frame: Week 4, 12, 24, 36, and 48
Percentage of Participants With On-treatment Failure
Participants were considered as an on-treatment failure if, at actual end of treatment (EOT), there was confirmed detectable HCV RNA levels.
Time frame: Week 1 to 48
Percentage of Participants With Viral Breakthrough
Confirmed increase of more than 1 log10 IU per mL in HCV RNA level from the lowest level reached, or a confirmed HCV RNA level of more than 100 IU per mL in participants whose HCV RNA levels had previously been below the limit of quantification (less than 25 IU per mL detectable) or undetectable (less than 25 IU per mL undetectable), while on study therapy.
Time frame: Week 1 to 48
Percentage of Participants With Viral Relapse
Participants were considered to have a viral relapse when, at actual end of treatment, HCV RNA levels were less than 25 IU per mL undetectable; and during the follow-up period, HCV RNA levels were more than or equal to 25 IU per mL.

Number of Participants Reporting Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs)
An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between administration of study drug and up to Day 126 that were absent before treatment or that worsened relative to pre-treatment state.
