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

Phase 3
Completed
Conditions
Hepatitis C
Interventions
Drug: ABT-450/ritonavir
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).

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Who Experienced Relapse12overall With and Without New HCV InfectionUp 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 NS5Bfrom 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
NameTimeMethod
Percentage of Participants Who Experienced Relapse12 Without and With New HCV InfectionFrom 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 InfectionFrom 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 InfectionUp 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.
