简要总结
This study is being done to find out if the addition of boceprevir to standard of care (SOC) treatment with peginterferon alfa-2b (PegIFN-2b) + ribavirin (RBV) is effective for participants with chronic hepatitis C (CHC) genotype 1 and cirrhosis who were not successfully treated by previous SOC. All participants will receive treatment with SOC alone for 4 weeks and then boceprevir will be added to the treatment regimen for 44 additional weeks of combined treatment.

研究组 & 干预措施
PegIFN-2b + RBV+ boceprevir
Participants will receive PegIFN-2b (once weekly, 1.5 µg/kg subcutaneously) + RBV (capsules, orally, weight-based dose from 800-1400 mg/day divided into two daily doses) for 4 weeks and then will receive 44 additional weeks of treatment with PegIFN-2b (once weekly, 1.5 µg/kg subcutaneously) + RBV (capsules, orally, weight-based dose from 800-1400 mg/day divided into two daily doses) + boceprevir (capsules, orally, 800 mg three times per day).
干预措施: boceprevir (Drug)

结局指标
主要结局
Percentage of Participants Who Achieve Sustained Virological Response at Follow-up Week 24 (SVR24)
时间窗: Week 72 (24 weeks after end of treatment)
Hepatitis C Virus (HCV) ribonucleic acid (RNA) was measured using a polymerase chain reaction assay. SVR24 was defined as HCV RNA less than the Limit of Quantification (\<25 International Units (IU)/mL) 24 weeks after the end of the Treatment Period.
Percentage of Participants With One or More Adverse Events
时间窗: Up to 48 weeks (Lead-in and Treatment Periods)
Adverse events were monitored during the Lead-in and Treatment Periods
Percentage of Participants With an Adverse Event Leading to Discontinuation of Study Medication
时间窗: Up to 48 weeks (Lead-in and Treatment Periods)
Adverse events were monitored during the Lead-in and Treatment Periods
