Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This multiple dose study will assess the safety, tolerability, pharmacokinetics and pharmacodynamics of grazoprevir (MK-5172) in Genotype (GT) 1 and GT3 Hepatitis C virus (HCV)- infected participants. The primary hypothesis is that administration of grazoprevir for 7 days is sufficiently safe and well tolerated in HCV-infected males.
