简要总结
This is a study designed to compare the safety and efficacy of 3 different doses of grazoprevir (MK-5172) combined with pegylated interferon alfa-2b (PEG-IFN) and ribavirin (RBV) in treatment-naïve participants with genotype 1 (GT1) chronic hepatitis C (CHC). Participants will receive 12 weeks of treatment with grazoprevir combined with Peg-IFN and RBV, and depending on response at Week 4 may go on to receive an additional 12 weeks of treatment with Peg-IFN and RBV.

结局指标
主要结局
Percentage of Participants Achieving Sustained Virologic Response at 12 Weeks After the End of Treatment (SVR12)
时间窗: 12 weeks after end of treatment (up to 36 weeks total)
Hepatitis C virus ribonucleic acid (HCV RNA) was measured using the Roche COBAS™ Taqman™ HCV Test, v2.0® assay, which has a lower limit of quantification of 25 IU/mL and a limit of detection of 9.3 IU/mL. SVR12 was defined as HCV RNA \<25 IU/mL (either target detected, unquantifiable or target not detected) 12 weeks after the end of all study therapy.
Number of Participants Experiencing at Least One Adverse Event (AE) During the Treatment Period and First 14 Follow-up Days
时间窗: 14 days following last dose of study drug (up to 26 weeks)
An adverse event is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol -specified procedure, whether or not considered related to the medicinal product or protocol -specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event.
Number of Participants Discontinued From Study Treatment Due to AEs During the Treatment Period and First 14 Follow-up Days
时间窗: Up to 24 weeks
