  Purpose

Study P05063 is a 3-year follow-up study in subjects previously treated with boceprevir or narlaprevir in a Phase 1, 2, or 3 clinical study. Subjects will be followed for up to 3.5 years after the end of their participation in the treatment protocol to document maintenance of the antiviral response (for sustained responders) and to characterize the long-term safety after use of this novel therapeutic regimen.
