Title: A Randomized, Open-Label, Phase 3 Study of Telaprevir Administered Twice Daily or Every 8 Hours in Combination With Pegylated Interferon Alfa-2a and Ribavirin in Treatment-Naïve Subjects With Genotype 1 Chronic Hepatitis C Virus Infection
Brief Summary: The purpose of this study is to evaluate the effectiveness of telaprevir administered twice daily versus every 8 hours in combination with Peg-IFN-alfa-2a and ribavirin in treatment-naïve participants with chronic HCV genotype 1 infection.


Options:
A: Inclusion Criteria:

* Patient has chronic HCV infection genotype 1 with HCV RNA level \> 1,000 IU/mL
* Patients should not have had any previous treatment for hepatitis C
* Patient must have documentation of a liver biopsy within 2 years before the screening visit or the patient must agree to have a biopsy performed within the screening period
* Patients with cirrhosis should have serum alpha-fetoprotein (AFP) \<= 50 ng/mL. If AFP \> 50 ng/mL, absence of a mass must be demonstrated by ultrasound within the screening period
* A female patient of childbearing potential and a nonvasectomized male patient who has a female partner of childbearing potential must agree to the use of 2 effective methods of birth control from screening until 6 months (female patient) or 7 months (male patient) after the last dose of RBV.

Exclusion Criteria:

* Patient is infected or co-infected with HCV of another genotype than genotype 1 and/or patient is infected with more than one genotype subtype
* Patient has a pre-existing psychiatric condition
* Patient has history of decompensated liver disease or shows evidence of significant liver disease in addition to hepatitis C
* Patient has human immunodeficiency virus (HIV) or hepatitis B virus (HBV) co-infection

* Liver biopsy obtained within 3 years (36 calendar months) prior to the Day 1 visit, with a fibrosis classification of non-cirrhotic. If no recent (\<36 months) liver biopsy is available, a study qualifying biopsy must be performed prior to Baseline (Day 1)
* All fertile males and females must use two forms of effective contraception between them during treatment and during the 24 weeks after treatment ends

* Participation in a clinical study with an investigational drug, biologic, or device within 3 months prior to first dose administration
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).

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.

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
