1. For inclusion in the study, subjects must have a qualifying regimen defined as PEG2a/ribavirin or peginterferon alfa-2b (PEG2b)/ribavirin for a minimum of 12 weeks. If a subject has received more than one such regimen, the most recent regimen is considered the qualifying regimen
Note: Maintenance therapy, following failure of qualifying therapy, with any interferon alfa is acceptable; however, the subject must have discontinued the maintenance therapy at least 1 month prior to the Screening Visit
2. During the qualifying regimen, subjects must have either:
a. A documented undetectable HCV-RNA within 30 days of EOT and a subsequent detectable HCV-RNA during follow-up OR
b. A documented decline in HCV-RNA by >/= 2 log10 by TW 12.
Note: For subjects who did not participate in Schering-Plough Research Institute (SPRI) protocols, qualifying virology reports and documentation of qualifying previous treatment regimen must be completely de-identified and faxed to the sponsor's project physician for confirmation that the subject qualifies for this study
3. Subject must have previously documented CHC genotype 1 infection. Subjects with other or mixed genotypes are not eligible. The HCV-RNA result obtained from the central laboratory at the Screening Visit must confirm genotype 1 infection and be equal or greater than 10,000 IU/mL
4. Subject must have a liver biopsy with histology consistent with CHC and no other etiology. Copies of the pathology report and slides are required for the subject to be included in the study. The study site must be able to access the pathology report and histology slides prior to subject randomization. Two unstained slides are preferred; however, one slide stained with hematoxylin plus eosin (H & E) plus one slide stained with Masson’s trichrome will be accepted (slides should be reviewed by the investigator to confirm adequacy). The central pathologist’s reading will be used for analysis purposes
a. No cirrhosis: Biopsy must be within 3 years of the Screening Visit
b. Cirrhosis: Any historic liver biopsy demonstrating cirrhosis will be accepted regardless of length of time since biopsy
c. Subjects whose timing of liver biopsy does not meet this criterion for subject eligibility may have a liver biopsy performed between Screening and Day 1, if their Screening Visit confirms that the subject meets the other study inclusion criteria
5. Subjects 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)
6. Subjects participating in SPRI maintenance protocols P02570 or P02569 must have completed the study (ie, finished last contact) to be eligible for this protocol
7. Subject must be 18 years of age
8. Subject must weigh between 40 kg and 125 kg
9. Subject and subject’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
10. Subjects must be willing to give written informed consent
Are the trial subjects under 18? no
Number o

b. Multi-drug abuse w/in 3 years of Screening Visit OR
c. Subjects receiving opiate agonist substitution therapy w/in 1 year of Screening (except for subjects monitored in an opioid substitution maintenance program) OR
