Trial Outcomes & Findings for 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) (NCT NCT01756079)
NCT ID: NCT01756079
Last Updated: 2018-09-05
Results Overview
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.
COMPLETED
PHASE4
58 participants
Week 72 (24 weeks after end of treatment)
2018-09-05
Participant Flow
A total of 130 participants were screened. Sixty participants passed screening, but 2 of these participants were excluded before assignment because standard of care treatment was not received during the Lead-in Period.

Overall Participants
Participants received 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 during the Lead-in Period and then 44 additional weeks of treatment in the Treatment Period receiving 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). After completion of treatment, follow-up continued for an additional 24 weeks.
