Title: A Phase IIa Randomized, Partially Blinded Trial of Telaprevir (VX-950) in Treatment-Naive Subjects With Chronic Genotype 4 Hepatitis C Infection
Brief Summary: The purpose of this study is to evaluate the activity and safety of telaprevir on Hepatitis C Virus (HCV) Genotype 4, alone or in combination with standard therapy, that is, pegylated-interferon-alfa-2a and ribavirin in treatment-naive (never been treated before with antiretroviral therapy) participants.


Options:
A: Inclusion Criteria: - Participant has chronic Genotype 4 Hepatitis C infection

* Plasma hepatitis C virus (HCV) ribonucleic acid (RNA) level greater than 10,000 International unit per milliliter (IU/mL) at Screening
* Participant never received treatment for HCV
* Participant was to be in good health (besides HCV infection), in the opinion of the Investigator, judged on the basis of medical history and physical examination (including vital signs and screening electrocardiogram \[ECG\]), with any chronic medical conditions under stable medical control
* Participant had to be willing to refrain from the concomitant use of any medications or substances Exclusion Criteria: - Participants with history or evidence of cirrhosis or history of suspicion of alcohol, barbiturate, or amphetamine recreational or narcotic drug use, which in the Investigator's opinion would compromise the participant's safety and/or compliance with study procedures
* Participant has human immunodeficiency virus (HIV) or hepatitis B virus (HBV) co-infection
* Female participants who are pregnant, or planning to become pregnant, or breastfeeding, and partners of female participants who are pregnant or breastfeeding
* Participant has hypersensitivity to tartrazine
* Participant had participated in any clinical trial for an investigational drug within 90 days before drug administration or participated in more than 2 drug studies in the last 12 months
B: 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.
C: Inclusion Criteria:

* Men and women, ages 18 to 70 years.
* Participants infected with hepatitis C virus (HCV) genotype 1, 2, or 3, with no previous exposure to an interferon formulation (ie, interferon-alpha, pegylated interferon-alpha) ribavirin, or other HCV-specific direct-acting antiviral (including daclatasvir and PSI-7977).
* Patients should have chronic hepatitis C genotype 1a, 1b, 2, or 3 as documented by: positive test results for anti-HCV antibody; HCV RNA; or a HCV genotype at least 6 months prior to screening, and HCV RNA and anti-HCV antibody at the time of screening.

Exclusion Criteria:

* Evidence of a medical condition associate with chronic liver disease other than HCV.
