Title: A Phase IIb, Randomized, Double-Blind, Placebo-Controlled Trial to Investigate the Efficacy, Tolerability, Safety and Pharmacokinetics of TMC435 as Part of a Treatment Regimen Including PegIFNa-2a and Ribavirin in HCV Genotype 1 Infected Subjects Who Failed Previous Standard Therapy
Brief Summary: The purpose of this study is to determine the efficacy, safety and tolerability of different regimens of TMC435 with standard treatment compared to standard treatment alone in participants with chronic, genotype 1, hepatitis C virus (HCV) infection who has failed previous treatment with pegylated interferon (Peg-INF-alfa-2a) and ribavirin (RBV).


Options:
A: Inclusion Criteria:

* Must have chronic hepatitis C infection as evidenced by liver biopsy, anti-hepatitis C virus (HCV) and HCV RNA positive
* Must have chronic hepatitis C infection (genotype 1) with HCV RNA level greater than10000 IU/mL
* Patient must have failed at least 1 prior course of peg interferon (Peg-IFN-alfa-2a)/ribavirin (RBV) therapy (standard treatment)
* Must be willing to use 2 effective methods of birth control for up to 7 months after last dose of study medication

Exclusion Criteria:

* Has an evidence of decompensated liver disease
* Co-infection with any other Hepatitis C virus genotype or co-infection with the human immunodeficiency virus (HIV)
* Has a medical condition which is a contraindication to Peg-INF or RBV therapy
* Have had history of, or any current medical condition which could impact the safety of the patient in the study
B: Inclusion Criteria:

* Chronically infected with Hepatitis C Virus (HCV) genotype 1
* Treatment naive or treatment non-responders or treatment intolerant; and not co-infected with HIV or Hepatitis B Virus
* HCV RNA viral load of ≥10\*5 IU/mL
* BMI 18 to 35kg/m²

Exclusion Criteria:

* Any significant acute or chronic medical illness which is not stable or is not controlled with medication and not consistent with Hepatitis C Virus infection
* HIV and/or HBV positive
* Major surgery within 4 weeks of study drug administration and any gastrointestinal surgery that could impact the absorption of study drug

WOCBP will be enrolled as in-patient for 16 days
C: Inclusion criteria:

1. Chronic hepatitis C infection, diagnosed by positive anti-HCV antibodies and detected HCV RNA at screening in addition to:

   1. positive anti-HCV antibodies or detected HCV RNA at least 6 months prior to screening; or,
   2. liver biopsy consistent with chronic HCV infection.
2. HCV genotype 1 infection confirmed by genotypic testing at screening.
3. Therapy-naïve to interferon, pegylated interferon, ribavirin or any antiviral / immunomodulatory drug for acute or chronic HCV infection.
4. HCV RNA = 1,000 IU/mL at screening
5. Documentation of a liver biopsy within 3 years or fibroscan within 6 months prior to randomization.

   Note: If cirrhosis has been previously demonstrated on a biopsy, then biopsies obtained more than 3 years before randomization need not be repeated. Biopsies may be waived for patients who would be placed at risk from the procedure. Inability to do a liver biopsy in patients at risk for the procedure should not exclude such patients from a trial.
6. Age 18 to 70 years
7. Female patients:

   1. with documented hysterectomy,
   2. who have had both ovaries removed,
   3. with documented tubal ligation,
   4. who are post-menopausal with last menstrual period at least 12 months prior to screening, or
   5. of childbearing potential with a negative serum pregnancy test at screening and Day 1, that, if sexually active, agree to use one of the appropriate medically accepted methods of birth control from the date of screening until 7 months after the last dose of ribavirin in addition to the consistent and correct use of a condom. Patients must agree not to breast-feed at any time from the date of screening until 7 months after the last dose of ribavirin.

   Medically accepted methods of contraception for females in this trial are ethinyl estradiol containing contraceptives, diaphragm with spermicide substance and intra-uterine device.

   Male patients:
   1. who are documented to be sterile, or
   2. who are without pregnant female partner(s) and consistently and correctly use a condom while their female partner(s) (if of child-bearing potential) use one of the appropriate medically accepted methods of birth control from the date of screening until 7 months after the last dose of ribavirin. It is in the responsibility of the male patient to ensure that his partner(s) is not pregnant prior to screening into the study or becomes pregnant during the treatment and the observation phase. Female partners of childbearing potential should perform monthly pregnancy tests from the date of screening until 7 months after the last dose of ribavirin (tests will be provided by the sponsor).
8. Signed informed consent form prior to trial participation

Exclusion criteria:

1. HCV infection of mixed genotype (1/2, 1/3, and 1/4) diagnosed by genotypic testing at screening
2. Evidence of acute or chronic liver disease due to causes other than chronic HCV infection. Incidental steatosis diagnosed by biopsy is not an exclusion criterion.
3. HIV co-infection
4. Hepatitis B virus (HBV) infection based on presence of HBs-Ag
5. Active malignancy, or history of malignancy within the last 5 years prior to screening (with an exception of appropriately treated basal cell carcinoma of the skin or in situ carcinoma of the uterine cervix)
6. Active or, history of alcohol or illicit drug abuse other than cannabis within the past 12 months
7. A condition that is defined as one which in the opinion of investigator may put the patient at risk because of participation in this study, may influence the results of this study, or limit the patients ability to participate in this study
8. Usage of any investigational drugs within 30 days prior to screening, or planned usage of an investigational drug during the course of this study.
9. Received concomitant systemic antiviral, hematopoietic growth factor, or immunomodulatory treatment within 30 days prior to randomization. Patients being treated with oral antivirals such as acyclovir, famciclovir or valacyclovir for recurrent herpes simplex infection; or with oseltamivir or zanamivir for influenza A infection, may be screened.
10. Received silymarin (milk thistle), glycyrrhizin, or Sho-saiko-to (SST) within 28 days prior to randomization and throughout the treatment phase of this trial.
11. Known hypersensitivity to any ingredient of the study drugs.
12. Alpha fetoprotein value \> 100 ng/mL at screening; if \> 20 ng/mL and = 100 ng/mL, patients may be included if there is no evidence of liver cancer in an appropriate imaging study (e.g., ultrasound, CT scan, or MRI) within last 6 months prior to randomization (Visit 2).

Other exclusion criteria related to pegylated interferon and/or ribavirin restrictions are not listed here.
