研究概览

简要总结

The primary objective of this study is to determine the safe and effective dose range of boceprevir (SCH 503034) in combination with PEG-Intron in adult subjects who have chronic hepatitis C without cirrhosis, and who have failed an adequate course of combination therapy with peginterferon-alfa plus ribavirin. A secondary objective is to explore whether ribavirin provides an additional benefit when combined with PEG-Intron plus boceprevir.

结局指标

主要结局

Percent of Participants Who Were Hepatitis C Virus Ribonucleic Acid (HCV-RNA) Negative at the End of Treatment (EoT)

时间窗: Baseline up to Week 49

Sustained Viral Response (SVR) was defined as the percentage of participants with HCV-RNA undetectable at the follow-up Week 24. All percentages were based on the total number of participants originally randomized/enrolled to that particular arm. For Arm 1B, the denominator for the percentages was the number who received at least 1 dose of BOC. Arm 1A was not analyzed.
