Title: A Phase 2 Study of VX-950 in Combination With Peginterferon Alfa-2a (Pegasys®), With and Without Ribavirin (Copegus®) in Subjects With Hepatitis C
Brief Summary: Compare the effectiveness of telaprevir (VX-950) in combination with Pegylated Interferon Alfa 2a (Peg-IFN-alfa-2a) with and without Ribavirin (RBV) in reducing plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels


Options:
A: Inclusion Criteria:

* Hepatitis C virus Genotype 1 with detectable plasma hepatitis C virus RNA
* Have been infected with Hepatitis C virus for greater than (\>) 6 months
* Seronegative for hepatitis B surface antigen and human immunodeficiency virus 1 and 2
* Must agree to use 2 methods of contraception, including 1 barrier method, during and for 24 weeks after the completion of the study (unless the subject is a female of documented non-child-bearing potential)
* Female subjects must have a negative pregnancy test at all visits before the first dose.

Exclusion Criteria:

* Received any approved or investigational drug or drug regimen for the treatment of hepatitis C.
* Any medical contraindications to Peg-IFN-alfa-2a or Ribavirin therapy
* Any other cause of significant liver disease in addition to hepatitis C; this may include but is not limited to, hepatitis B, drug or alcohol-related cirrhosis, autoimmune hepatitis, hemochromatosis, Wilson's disease, Nonalcoholic Steatohepatitis or primary biliary cirrhosis.
* Diagnosed or suspected hepatocellular carcinoma.
* Histologic evidence of hepatic cirrhosis (including compensated cirrhosis) based on a liver biopsy taken within 2 years before Study start.
* Alcohol/drug abuse or excessive use in the last 12 months.
* Participation in any investigational drug study within 90 days before drug administration or participation in more than 2 drug studies in the last 12 months (exclusive of the current study).
B: Inclusion Criteria:

* adult patients, 18-65 years of age;
* chronic hepatitis C, genotype 1.

Exclusion Criteria:

* decompensated liver disease, or impaired liver function;
* presence or history of non-hepatitis C chronic liver disease;
* HBsAg or HIV infection;
* history of cancer within 5 years, other than localized or in situ cancer of the skin.
C: Inclusion Criteria:

* Males and females between 18 and 70 years old
* Detectable plasma hepatitis C virus (HCV) ribonucleic acid (RNA) greater than or equal to (\>=) 10,000 international units per milliliter (IU/mL)
* Must have chronic hepatitis C (genotype 1) and have already received at least one prior course of pegylated interferon alfa 2a with ribavirin
* Cannot also be infected with Human Immunodeficiency Virus or hepatitis B
* Must be judged to be in general good health and able to receive Pegasys® and Copegus®
* No drug or alcohol abuse in the last year
* Must agree to use two effective methods of birth control during the study and for 6 months after you stop taking study medication. One of the methods needs to be a 'barrier' method (condom or diaphragm)
* If you are a woman, you cannot be in this study if you are pregnant or nursing

Exclusion Criteria:

* Participation in any clinical trial of a HCV protease inhibitor of any duration
* Prior response to therapy and failure to achieve SVR which was due to treatment non-compliance
* Any other cause of significant liver disease in addition to hepatitis C; this may include but is not limited to, hepatitis B, drug or alcohol-related cirrhosis, autoimmune hepatitis, hemochromatosis, Wilson's disease, nonalcoholic steatohepatitis, or primary biliary cirrhosis
* Diagnosed or suspected hepatocellular carcinoma
* History of or current evidence of decompensated liver disease
* Participation in any clinical trial of an investigational drug within 90 days before drug administration or participation in more than 2 drug studies in the last 12 months (exclusive of the current study)
D: Inclusion Criteria:

* Genotype 1 hepatitis C infection (confirmed at screening)
* Participant has not received any prior treatment for hepatitis C
* Participant must have had a liver biopsy within 3 years before screening (or between the screening and baseline visit) showing chronic hepatitis C infection
* Must agree to use 2 forms of effective contraception throughout study (both males and females)

Exclusion Criteria:

* Infection with HIV or non genotype 1 hepatitis C
* Liver disease not related to hepatitic C infection
* Hepatic decompensation
* Significant laboratory abnormalities or other active diseases
* Pregnant or planning to become pregnant
