Title: A Randomized Study of Stopping Treatment at 24 Weeks or Continuing Treatment to 48 Weeks in Treatment-Naïve Subjects With Genotype 1 Chronic Hepatitis C Who Achieve an Extended Rapid Viral Response While Receiving Telaprevir, Peginterferon Alfa2a (Pegasys®) and Ribavirin (Copegus®)
Brief Summary: This study is being conducted to learn more about the safety and effect of telaprevir in combination with peginterferon alfa-2a (PEG-IFN) and ribavirin (RBV) in participants with hepatitis C who have never been treated for their hepatitis C virus (HCV). The study is designed to look at the relative benefits of 24 or 48 weeks of total treatment in people who respond quickly to a telaprevir-based treatment.


Options:
A: 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.
* History of variceal bleeding, hepatic encephalopathy, or ascites requiring management with diuretics or paracentesis.
* History of hemophilia.
* History of torsade de pointes.
* Current or known history of cancer (except in situ carcinoma of the cervix or adequately treated basal or squamous cell carcinoma of the skin) within 5 years prior to enrollment.
* History of gastrointestinal disease or surgical procedure (except cholecystectomy).
* History of clinically significant cardiac disease.
* Blood transfusion within 4 weeks prior to study drug administration.
* Poor venous access.
* Any other medical, psychiatric, and/or social reason which, in the opinion of the Investigator, would make the candidate inappropriate for participation in this study.
B: Inclusion Criteria:

* Has not received any previous treatment with any approved or investigational drug or drug regimen for the treatment of hepatitis C
* Male and female subjects, 18 to 70 years of age, inclusive
* Genotype 1, chronic hepatitis C with detectable HCV RNA.
* Screening laboratory values, tests, and physical exam within acceptable ranges
* Able and willing to follow contraception requirements
* Able to read and understand, and willing to sign the informed consent form and abide by the study restrictions.

Exclusion Criteria:

* Subject has any contraindications to Pegasys® or Copegus® therapy
* Evidence of hepatic decompensation in cirrhotic subjects
* History of organ transplant
* History of, or any current medical condition which could impact the safety of the subject in participation in the study
C: Inclusion Criteria

* Has not received any previous treatment with any approved or investigational drug or drug regimen for the treatment of hepatitis C
* Male and female subjects, 18 to 70 years of age, inclusive
* Genotype 1, chronic hepatitis C with detectable Hepatitis C Virus (HCV) Ribonucleic Acid (RNA)
* Screening laboratory values, tests, and physical exam within acceptable ranges
* Able and willing to follow contraception requirements
* Able to read and understand, and willing to sign the informed consent form and abide by the study restrictions

Exclusion Criteria

* Subject has any contraindications to Pegasys® or Copegus® therapy
* Evidence of hepatic decompensation in cirrhotic subjects
* History of organ transplant
* History of, or any current medical condition which could impact the safety of the subject in participation in the study
D: Inclusion Criteria:

* Chronic Genotype 2 or 3 HCV-infection
* Naive to all HCV antiviral treatment(s)

Exclusion Criteria:

* Positive test at Screening for HBsAg, anti-hepatitis B core immunoglobulin M antibody (anti-HBc IgM Ab), or anti-HIV Ab
* History of any other clinically significant chronic liver disease
* A history consistent with decompensated liver disease
* History or current evidence of psychiatric illness, immunologic disorder, hemoglobinopathy, pulmonary or cardiac disease, seizure disorder or anticonvulsant use, poorly controlled diabetes, cancer, or a history of malignancy, that makes the subject unsuitable for the study.
* Participation in a clinical study within 3 months prior to first dose
