A Long Term Follow-up Registry for Adolescent and Pediatric Subjects Who Received a Gilead Hepatitis C Virus Direct Acting Antiviral (DAA) in Gilead-Sponsored Chronic Hepatitis C Infection Trials

GS-US-334-1113

This Registry will enroll adolescent and pediatric participants who received at least one Gilead Hepatitis C Virus (HCV) direct acting antiviral (DAA) while participating in a Gilead-sponsored chronic hepatitis C clinical trial. The primary objective of this Registry is to determine the long-term safety of anti-HCV regimens in the pediatric population. Secondary objectives of this Registry are to determine whether subsequent detection of HCV RNA in participants who relapse following sustained virologic response (SVR) represents the re-emergence of pre-existing virus, the development of resistance mutations, or whether it is due to re-infection, and to characterize resistance mutations and the persistence of resistance mutations in pediatric participants who did not achieve SVR. Once enrolled, participants will be followed for up to 5 years.
