A Study to Evaluate the Efficacy and Safety of Boceprevir Added to Standard of Care Therapy in Previously Treated Participants With Chronic Hepatitis C Genotype 1 and Cirrhosis (MK-3034-105)
- Registration Number
- NCT01756079
- Lead Sponsor
- Merck Sharp & Dohme LLC
- Brief Summary
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.

Group Intervention Description PegIFN-2b + RBV+ boceprevir PegIFN-2b 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). PegIFN-2b + RBV+ boceprevir 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). PegIFN-2b + RBV+ boceprevir RBV 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).
- Primary Outcome Measures
Name Time Method Percentage of Participants Who Achieve Sustained Virological Response at Follow-up Week 24 (SVR24) 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 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 Up to 48 weeks (Lead-in and Treatment Periods) Adverse events were monitored during the Lead-in and Treatment Periods
