A Follow up Study Designed to Obtain Long Term Data on Participants Who Either Achieved a Sustained Virologic Response or Did Not Achieve a Sustained Virologic Response in an AbbVie Sponsored Hepatitis C Study
- Registration Number
- NCT01773070
- Lead Sponsor
- AbbVie (prior sponsor, Abbott)
- Brief Summary
A follow-up study to assess resistance and durability of response to 3 experimental drugs ABT-450/r, ABT-267, and ABT-333 in participants who have participated in AbbVie Phase 2 or 3 clinical studies with these agents for the treatment of chronic hepatitis C virus (HCV). Studies include: M11-646 (NCT01716585), M11-652 (NCT01464827), M12-746 (NCT01306617), M12-998 (NCT01458535), M13-098 (NCT01715415), M13-099 (NCT01704755), M13-386 (NCT01563536), M13-389 (NCT01674725)' M13-393 (NCT01685203), M13-961 (NCT01767116), M14-002 (NCT01833533), and M14-103 (NCT01911845).

Group Intervention Description All Participants ABT-450/ritonavir Participants who received ABT-450, ABT-333 or ABT-267 at any dose level in an eligible prior AbbVie Phase 2 or 3 study for the treatment of chronic HCV, followed for up to 3 years post-treatment. All Participants ABT-267 Participants who received ABT-450, ABT-333 or ABT-267 at any dose level in an eligible prior AbbVie Phase 2 or 3 study for the treatment of chronic HCV, followed for up to 3 years post-treatment. All Participants ABT-333 Participants who received ABT-450, ABT-333 or ABT-267 at any dose level in an eligible prior AbbVie Phase 2 or 3 study for the treatment of chronic HCV, followed for up to 3 years post-treatment.
- Primary Outcome Measures
Name Time Method Percentage of Participants Who Experienced Relapse12overall With and Without New HCV Infection Up to 3 years post-treatment Relapse is defined as a confirmed HCV ribonucleic acid (RNA) ≥ the lower limit of quantitation (LLOQ) at any time during the post-treatment period for a participant who had HCV RNA \< LLOQ at the end of treatment. Relapse12overall is defined as a confirmed HCV RNA ≥ LLOQ at any time after the sustained virologic response at Week 12 post-dosing (SVR12) assessment time point for a participant who achieved SVR12 and had post-SVR12 HCV RNA data available. SVR12 is defined as HCV RNA \< LLOQ in the SVR12 window (12 weeks after the last actual dose of study drug) without any confirmed quantifiable (≥ LLOQ) post-treatment value before or during that SVR window. New HCV infection is defined as re-infection with a different HCV isolate.
Number of HCV Genotype (GT)1a-Infected Participants With Persistence of Treatment-Emergent Substitutions in NS3, NS5A, or NS5B from the last dose of study drug in the previous study up to 3 years post-treatment The persistence of specific hepatitis C amino acid variants (treatment-emergent substitutions) associated with drug resistance in NS3, NS5A, or NS5B was evaluated in participants who had not achieved SVR12. Post-baseline time points were calculated relative to the last dose of study drug in the previous study.
- Secondary Outcome Measures
Name Time Method Percentage of Participants Who Experienced Relapse12 Without and With New HCV Infection From the end of treatment through 12 weeks post-treatment Relapse is defined as a confirmed HCV RNA ≥ LLOQ at any time during the post-treatment period for a participant who had HCV RNA \< LLOQ at the end of treatment. Relapse12 is defined as a confirmed HCV RNA ≥ LLOQ between end of treatment and 12 weeks after last actual dose of study drug (up to and including the SVR12 assessment time point) for a participant with HCV RNA \< LLOQ at Final Treatment Visit who completed treatment.
Percentage of Participants Who Experienced Relapse24 Without and With New HCV Infection From the end of treatment through 24 weeks post-treatment Relapse is defined as a confirmed HCV RNA ≥ LLOQ at any time during the post-treatment period for a participant who had HCV RNA \< LLOQ at the end of treatment. Relapse24 is defined as a confirmed HCV RNA ≥ LLOQ within the sustained virologic response at Week 24 post-dosing (SVR24) window for a participant who achieved SVR12 and had HCV RNA data available in the SVR24 window.
Percentage of Participants Who Experienced Relapse˅Overall Without and With New HCV Infection Up to 3 years post-treatment Relapse is defined as a confirmed HCV RNA ≥ LLOQ at any time during the post-treatment period for a participant who had HCV RNA \< LLOQ at the end of treatment. Relapse˅overall was defined as a confirmed HCV RNA ≥ LLOQ between end of treatment and up to and including the last HCV RNA measurement collected in the post-treatment Period for a participant with HCV RNA \< LLOQ at Final Treatment Visit who completed treatment.
