3-Year Observational Virology Follow-up Study in Subjects Who Participated in Studies of Idenix Anti-HCV, Direct Acting Antivirals
All subjects in this study have previously been in an Idenix HCV study and received study drug for 3 consecutive days. Subjects who had received placebo in a previous Idenix study will not be enrolled in this study.
In this study, researchers will try to find answers to these questions:
- How much (if any) hepatitis C virus is in your blood after stopping your Idenix study drug?
- Is your hepatitis C virus possibly resistant to treatment with the Idenix study drug or similar drugs?
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||3-Year, Observational Study to Evaluate the Durability of Sustained Viral Response and the Kinetics of Antiviral-Resistant HCV in Subjects Who Participated in Studies of Idenix Anti-HCV, Direct Acting Antivirals|
- Durability of Sustained viral response [SVR] [ Time Frame: every 3 months ]To evaluate the durability of sustained virological response (SVR). Plasma HCV RNA levels will be monitored over time.
- Kinetics of resistant variants [ Time Frame: every 3 months ]To describe the kinetics of resistant variants to Idenix direct acting antivirals (DAAs) by HCV RNA sequencing. The presence of each identified resistant variant in the viral population will be descriptively evaluated until the viral population consists entirely of wild-type virus or over a period of 3 years, whichever comes first.
