Clinical Trial Summary

The purpose of this study is to evaluate the safety and efficacy of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) coadministered with ribavirin (RBV) in hepatitis C virus (HCV) genotype 1-infected adults with compensated cirrhosis.

Description:

During the treatment period of the study, participants received treatment with ABT-450/ritonavir/ABT-267 and ABT-333 coadministered with RBV for either 12 or 24 weeks. Upon completing the treatment period or premature discontinuation of the treatment period, participants entered a 48-week post-treatment period.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment	The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ]) 12 weeks after the last dose of study drug.	12 weeks after the last actual dose of study drug
Secondary	Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment in the 24-week Arm Compared to the 12-week Arm	A sustained virologic response is defined as plasma Hepatitis C virus ribonucleic acid (HCV RNA) less than the lower limit of quantification (< LLOQ) 12 weeks after the last dose of study drug.	12 weeks after the last actual dose of study drug
Secondary	Percentage of Participants in Each Arm With On-treatment Virologic Failure During the Treatment Period	Virologic failure during treatment was defined as rebound (confirmed HCV RNA greater than or equal to the lower limit of quantitation [= LLOQ] after HCV RNA < LLOQ during treatment, or confirmed increase from the lowest value post baseline in HCV RNA [2 consecutive HCV RNA measurements > 1 log(subscript)10(subscript) IU/mL above the lowest value post baseline] at any time point during treatment), or fail to suppress (HCV RNA = LLOQ persistently during treatment with at least 6 weeks [= 36 days] of treatment).	Baseline (Day 1), and Treatment Weeks 1, 2, 4, 6, 8, 10, 12, 16, 20, and 24
Secondary	Percentage of Participants With Virologic Relapse After Treatment	Participants were considered to have virologic relapse after treatment if they had confirmed quantifiable plasma Hepatitis C virus ribonucleic acid (HCV RNA) = lower limit of quantification (LLOQ) between the end of treatment and 12 weeks after the last dose of study drug among participants who completed treatment with HCV RNA < LLOQ at the end of treatment.	within 12 weeks after the last dose of study drug
