Brief Summary

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

This study will assess short term safety, antiviral activity and pharmacokinetics (PK) of IDX184 in combination with Peg-interferon (Peg-IFN)/Ribavirin (RBV) in participants with hepatitis C virus (HCV) genotype (GT) 1 infection. These data will guide dose selection for future, longer term studies.
