Trial Overview

Trial Outcomes

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 quantification [< LLOQ]) 12 weeks after the last dose of study drug. (NCT01911845)
Timeframe: 12 weeks after the last actual dose of study drug

Percentage of Participants With Virologic Failure During Treatment

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. (NCT01911845)
Timeframe: Baseline (Day 1), and Treatment Weeks 1, 2, 4, 6, 8, 10, and 12

Percentage of Participants With Virologic Relapse Post-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. Completion of treatment was defined as a study drug duration ≥ 77 days. (NCT01911845)
Timeframe: From the end of treatment through 12 weeks after the last actual dose of study drug

Area Under the Plasma Concentration-time Curve (AUC) for ABT-450, Ritonavir, ABT-267, ABT-333, ABT-333 M1 Metabolite, and Ribavirin

Blood samples were collected pre-dose (time 0) and at 2, 4, 6, and 24 hours post-dose at one visit between treatment week 2 and treatment week 12, and were analyzed using validated analytical methods. A total of 22/38 participants consented for intensive pharmacokinetic blood sampling. Area under the plasma concentration-time curve from time 0 to 24 hours (AUC24 in ng*hr/mL)] was estimated using noncompartmental analyses. For ABT-450, ritonavir, and ABT-267, the AUC from time 0 to the last measureable concentration (AUCt in ng*hr/mL) was calculated instead of AUC24 due to time deviations at 24 hours. The AUCt values are approximately equivalent to AUC24. For ABT-333, ABT-333 M1, and RBV, the AUC from time 0 to 12 hours (AUC12 in ng*hr/mL) after the morning dose was calculated using the 24-hour concentration as the 12-hour concentration as dosing was twice a day and a 12-hour sample was not collected in this study. (NCT01911845)
Timeframe: Pre-dose (time 0) and 2, 4, 6, and 24 hours post-dose

Maximum Plasma Concentration (Cmax) for ABT-450, Ritonavir, ABT-267, ABT-333, ABT-333 M1 Metabolite, and Ribavirin

Blood samples were collected pre-dose (time 0) and at 2, 4, 6, and 24 hours post-dose at one visit between treatment week 2 and treatment week 12, and were analyzed using validated analytical methods. A total of 22/38 participants consented for intensive pharmacokinetic blood sampling. Maximum plasma concentration (Cmax; measured in ng/mL) was directly determined from the concentration-time data. (NCT01911845)
Timeframe: Pre-dose (time 0) and 2, 4, 6, and 24 hours post-dose

Plasma Trough Concentration (Ctrough) for ABT-450, Ritonavir, ABT-267, ABT-333, ABT-333 M1 Metabolite, and Ribavirin

Blood samples were collected pre-dose (time 0) and at 2, 4, 6, and 24 hours post-dose at one visit between treatment week 2 and treatment week 12, and analyzed using validated analytical methods. A total of 22/38 participants consented for intensive pharmacokinetic blood sampling. Minimum plasma concentration (C trough; measured in ng/mL) was directly determined from the concentration-time data. (NCT01911845)
Timeframe: Pre-dose (time 0) and 2, 4, 6, and 24 hours post-dose

Time to Maximum Plasma Concentration (Tmax) for ABT-450, Ritonavir, ABT-267, ABT-333, ABT-333 M1 Metabolite, and Ribavirin

Blood samples were collected pre-dose (time 0) and at 2, 4, 6, and 24 hours post-dose at one visit between treatment week 2 and treatment week 12, and analyzed using validated analytical methods. A total of 22/38 participants consented for intensive pharmacokinetic blood sampling. The time to maximum plasma concentration (Tmax; measured in hours) was directly determined from the concentration-time data. (NCT01911845)
Timeframe: Pre-dose (time 0) and 2, 4, 6, and 24 hours post-dose
