Study Endpoints
Primary Endpoints
Percentage of Participants Achieving Sustained Viral Response (SVR) at Follow-up Week 24 (FW24) Among Randomized Participants Who Received At Least One Dose of Trial Medication
Up to Week 72

SVR24 is defined as undetectable plasma hepatitis C virus ribonucleic acid (HCV-RNA) at 24 weeks after the end of all study treatment. If there was no value in the FW24 visit window, the closest value available chronologically after this window was used; if a value was still missing after that, the value from Follow-up Week 12 (FW12) was used. HCV-RNA is detected by a nucleic acid amplification test and the lower limit of detection for this assay is 9.3 IU/mL.

Secondary Endpoints
Percentage of Participants Achieving SVR24 Among Randomized Participants Who Received At Least One Dose of Boceprevir (Experimental) or Placebo (Control)
Up to Week 72
Percentage of Participants With Early Virologic Response (EVR) Who Achieved SVR24

PegIFN-2b + RBVPLACEBO_COMPARATORPegIFN-2b (1.5 µg/kg/week subcutaneously) plus RBV (600-1400 mg/day, orally, divided into two daily doses) for 4 weeks followed by placebo to boceprevir plus PegIFN-2b/RBV for 44 weeks with 24 weeks post-treatment follow-up (Control Arm). Participants who do not achieve HCV-RNA \<9.3 IU/mL by Treatment Week 24 (TW24) are eligible to cross-over and receive boceprevir along with the PegIFN-2b and RBV for up to 44 weeks.
PegIFN-2b + RBV + BoceprevirACTIVE_COMPARATORPegIFN-2b (1.5 µg/kg/week subcutaneously) plus RBV (600- 1400 mg/day, orally, divided into two daily doses) for 4 weeks followed by boceprevir (800 mg, orally, 3 times per day) plus PegIFN-2b/RBV for 44 weeks with 24 weeks post-treatment follow-up.
