Title: A Phase 3, Safety and Efficacy Study of Boceprevir in Previously Untreated Subjects With Chronic Hepatitis C Genotype 1
Brief Summary: This study involves treatment with boceprevir or placebo in combination with PegIntron (PEG) + Ribavirin (RBV) (weight-based dosing \[WBD\]) in previously untreated adult participants with chronic hepatitis C (CHC) genotype 1. It is hypothesized that the addition of a third active anti- Hepatitis C Virus (anti-HCV) drug may lead to more rapid viral response than therapy with two drugs, and therefore, the addition of boceprevir to PegIntron plus ribavirin therapy after a 4-week lead-in period may allow for both increased rates of sustained virologic response (SVR) and shorter treatment durations (in some populations) than treatment with PegIntron plus ribavirin alone.

The study includes two separate cohorts, Cohort I (White participants) and Cohort II (Black participants). Participants from each cohort are assigned (randomized) to one of three study arms, all of which have a 4-week lead-in period with (PEG + RBV).


Options:
A: Inclusion Criteria:

* Participant must have previously documented CHC genotype 1 infection.
* Participant must have a liver biopsy with histology consistent with CHC and no other etiology.
* Participants with bridging fibrosis or cirrhosis must have an ultrasound within 6 months of the Screening Visit (or between Screening and Day 1) with no findings suspicious for hepatocellular carcinoma (HCC).
* Participant must be \>=18 years of age.
* Participant must weigh between 40 kg and 125 kg.
* Participant and participant's partner(s) must each agree to use acceptable methods of contraception for at least 2 weeks prior to Day 1 and continue until at least 6 months after last dose of study drug, or longer if dictated by local regulations.
* Participants must be willing to give written informed consent.

Exclusion Criteria:

* Coinfection with the human immunodeficiency virus (HIV) or hepatitis B virus (HBsAg positive).
* Participants who received prior treatment for hepatitis C; other than herbal remedies, except those with known hepatotoxicity.
* Treatment with any investigational drug within 30 days of the randomization visit in this study.
* Participation in any other clinical trial within 30 days of randomization or intention to participate in another clinical trial during participation in this study.
* Evidence of decompensated liver disease including, but not limited to, a history or presence of clinical ascites, bleeding varices, or hepatic encephalopathy.
* Diabetic and/or hypertensive participants with clinically significant ocular examination findings: retinopathy, cotton wool spots, optic nerve disorder, retinal hemorrhage, or any other clinically significant abnormality.
* Pre-existing psychiatric condition(s).
* Clinical diagnosis of substance abuse of the specified drugs within the specified timeframes.
* Any known pre-existing medical condition that could interfere with the participant's participation in and completion of the study.
* Evidence of active or suspected malignancy, or a history of malignancy, within the last 5 years (except adequately treated carcinoma in situ and basal cell carcinoma of the skin). Participants under evaluation for malignancy are not eligible.
* Participants who are pregnant or nursing. Participants who intend to become pregnant during the study period. Male participants with partners who are, or intend to become, pregnant during the study period.
* Any other condition which, in the opinion of a physician, would make the participant unsuitable for enrollment or could interfere with the participant participating in and completing the study.
* Participants who are part of the site personnel directly involved with this study.
* Participants who are family members of the investigational study staff.
* Participants who had life-threatening serious adverse event (SAE) during screening period.
* Protocol-specified hematologic, biochemical, and serologic criteria: Hemoglobin \<12 g/dL for females and \<13 g/dL for males; Neutrophils \<1500/mm\^3 (blacks: \<1200/mm\^3); Platelets \<100,000/mm\^3; Direct bilirubin \>1.5 x upper limit of normal (ULN)
* Serum albumin \< lower limit of normal (LLN)
* Thyroid-stimulating hormone (TSH) \>1.2 x ULN or \<0.8 x LLN of laboratory, with certain exceptions.
* Serum creatinine \>ULN of the laboratory reference.
* Protocol-specified serum glucose concentrations.
* protocol-specified alpha fetoprotein levels.
* Prothrombin time/partial thromboplastin time (PT/PTT) values \>10% above laboratory reference range.
* Anti-nuclear antibodies (ANA) \>1:320.
B: Inclusion Criteria:

* Chronically infected with HCV genotype 1
* Treatment naive or treatment non-responders or treatment intolerant
* HCV RNA viral load of ≥10\*5\* IU/mL
* BMI 18 to 35 kg/m²

Exclusion Criteria:

* Any significant acute or chronic medical illness which is not stable or is not controlled with medication and not consistent with HCV infection
* Major surgery within 4 weeks of study drug administration and any gastrointestinal surgery that could impact the absorption of study drug
* Co-infection with HIV or HBV
C: Inclusion Criteria:

* Patient must have had a liver biopsy before screening (or between the screening and baseline visit), unless patient cannot undergo such a procedure or has evidence of portal hypertension not associated with cirrhosis. For patients who had a liver biopsy performed more than 2 years prior to screening or without a biopsy (because of a contraindication or portal hypertension), a non-invasive staging assessment needs to be available. Non-invasive staging assessments include FibroScan, MR-Elastography, or FibroTest/FibroSure and must not be older than 6 months prior to screening
* Chronicity of hepatitis C virus (HCV) infection, as confirmed by one or both of the following: presence of anti-HCV antibody and/or HCV ribonucleic acid (RNA) at least 6 months prior to the screening visit and/or presence of fibrosis on biopsy
* Genotype 1 HCV infection with plasma HCV RNA of \>10,000 IU/mL (both confirmed at screening)
* Patient must have had at least 1 documented previous course of treatment with PegINFα-2a or PegINFα-2b in combination with ribavirin (RBV) (at least 12 weeks for null responder and 20 weeks for partial responder)

Exclusion Criteria:

* Hepatic decompensation (impaired functioning of the liver), as indicated by significant laboratory abnormalities or other active diseases
* Infection with Human Immunodeficiency Virus (HIV) or non genotype 1 hepatitis C
* Liver disease not related to hepatitis C infection
* Previous chronic hepatitis C treatment, other than PegIFN and RBV
D: Inclusion Criteria:

* Infection with HCV genotype 1, 4, 5, or 6
* Cirrhosis determination
* Subject met the following classifications:

  * Treatment-naive
  * Screening laboratory values within defined thresholds
  * Not treated with any investigational drug or device within 30 days of screening
* Use of highly effective contraception methods if female of childbearing potential or sexually active male

Exclusion Criteria:

* Prior exposure to an direct-acting antiviral targeting the HCV nonstructural protein (NS)5B polymerase
* Pregnant or nursing female, or male with pregnant female partner
* Current or prior history of clinical hepatic decompensation
* History of clinically-significant illness or any other major medical disorder that may have interfered with subject treatment, assessment, or compliance with the protocol
* Excessive alcohol ingestion or significant drug abuse
