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.

Condition Intervention Phase

Drug: boceprevir
Biological: PegIFN-2b

Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: A Multi-centre Single-arm Study to Evaluate the Efficacy and Safety of BOCEPREVIR 44 Weeks in Addition to Standard of Care (SOC) in Previously Treatment Failure (Relapser, Non-responders, Both Partial and Null) Patients With Chronic Hepatitis C Genotype 1 (G1) and Cirrhosis (F4 Metavir).

Primary Outcome Measures:
  • Percentage of Participants Who Achieve Sustained Virological Response at Follow-up Week 24 (SVR24) [ Time Frame: 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 [ Time Frame: 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 [ Time Frame: Up to 48 weeks (Lead-in and Treatment Periods) ]
    Adverse events were monitored during the Lead-in and Treatment Periods

Enrollment: 58
Study Start Date: February 2013
Study Completion Date: November 2015
Primary Completion Date: November 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 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).
