3-Year Observational Virology Follow-up Study in Subjects Who Participated in Studies of Idenix Anti-HCV, Direct Acting Antivirals

This study has been terminated.
Information provided by (Responsible Party):
Merck Sharp & Dohme Corp. Identifier:
First received: October 31, 2012
Last updated: April 15, 2015
Last verified: April 2015

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?

Hepatitis C

Study Type: Observational
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

Further study details as provided by Merck Sharp & Dohme Corp.:

Primary Outcome Measures:
  • 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.

Secondary Outcome Measures:
  • 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.

Biospecimen Retention:   Samples Without DNA
Human plasma

Enrollment: 145
Study Start Date: October 2012
Study Completion Date: March 2015
Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
Detailed Description:
The data obtained from this study will be used to further understand the long-term efficacy of Idenix DAAs used to treat HCV infection and to further understand HCV resistance to Idenix DAAs.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
The population will include subjects who participated in studies of Idenix anti-HCV DAAs.

Inclusion Criteria:

  • Have participated in an Idenix-sponsored study of an Idenix DAA
  • Received at least 3 consecutive days of DAA treatment in an Idenix-sponsored study
  • Agreed to comply with the visit schedule and laboratory tests

Exclusion Criteria:

  • Treatment with placebo only, in an Idenix sponsored study
  • Antiviral treatment for HCV after participation in an Idenix sponsored study of an Idenix DAA
