Brief 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 taking methadone or buprenorphine ± naloxone.
Detailed description
This study consisted of 2 periods: a 12-week treatment period and a 48-week post-treatment period (for all participants who received study drugs). All participants who received at least 1 dose of study drug were to be followed for 48 weeks post-treatment to monitor for safety, HCV RNA, the emergence and/or persistence of resistant viral variants, and assessment of patient-reported outcome (PRO) instruments.

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.
