Department(s) or Division(s)
Liver Diseases


The purpose of this study is to evaluate the response the subject had after they have completed participation in a Merck-sponsored treatment study for hepatitis C.

They may qualify to take part in this research study because they have previously participated in a Merck-sponsored study for treating chronic hepatitis C (HCV) infection and they responded to that treatment.  This study is a long term follow-up Registry study.  No study medication will be administered.

Subject participation in this research study is expected to last 3 to 5 years depending on which parent study they participated in initially.
