研究概览
简要总结
This study assessed the safety, tolerability, pharmacokinetics, and antiviral activity of multiple oral doses of ABT-450/ritonavir (r), ABT-333 (also known as dasabuvir), or ABT-072 in hepatitis C virus (HCV), genotype 1-infected, treatment-naïve adults.
详细描述
This was a Phase 2a, randomized, blinded, placebo-controlled, dose-ranging study in chronically, hepatitis C virus (HCV) genotype 1-infected participants designed to explore the safety, tolerability, pharmacokinetics, antiviral activity, as well as the evolution and persistence to resistance of ABT-450/r, ABT-333, or ABT-072. Participants were treated with ABT-450/r, ABT-333, or ABT-072 monotherapy for 3 days, followed by 81 days (12 weeks minus 3 days of monotherapy) of ABT-450/r, ABT-333, or ABT-072 combined with pegylated interferon/ribavirin (pegIFN/RBV), followed by 36 weeks of pegIFN/RBV alone. Participants randomized to an ABT-450/r treatment group who achieved rapid virologic response (RVR) and had HCV ribonucleic acid (RNA) levels < 25 IU/mL at all subsequent visits were eligible to stop pegIFN/RBV therapy on or after Week 24.

结局指标
主要结局
Maximal Change From Baseline in Hepatitis C Virus Ribonucleic Acid (HCV RNA) Levels During ABT-450/r, ABT-333, or ABT-072 Monotherapy Treatment
时间窗: Prior to dosing on Day 1 to before the morning dose on Day 4
Plasma HCV RNA levels (reported as log10 IU/mL) were determined for each sample using a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay that had a lower limit of detection of 10 IU/mL and a lower limit of quantification of 25 IU/mL. The baseline value was the HCV RNA level before the first dose of study drug on Day 1. The maximal change during monotherapy was the difference from baseline to the lowest log10 HCV RNA level anytime after the first dose of study drug on Day 1 through the last log10 HCV RNA level before the first dose of study drug on Day 4. Data are reported as the mean ± standard deviation.

时间窗: Immediately prior to morning dose (time 0 hours); 2, 4, 8, 12, and 16 hours after the morning dose on Day 1; and prior to dose on Day 2 (24 hours after Day 1 dose)
Blood samples were collected immediately prior to morning dose (time 0 hours); 2, 4, 8, 12, and 16 hours after the morning dose on Day 1; and prior to dose on Day 2 (24 hours after Day 1 dose). The samples were analyzed for the concentration of ABT-072 using validated analytical methods. The area under the plasma concentration-time curve (AUC; measured in ng\*hr/mL) is a method of measurement to determine the total exposure of a drug in blood plasma. The AUC24 of ABT-072 was estimated using non-compartmental methods and data are reported as the mean ± standard deviation.
Time to Maximum Plasma Concentration (Tmax) of ABT-333
时间窗: Immediately prior to morning dose (time 0 hours); 2, 4, 8, 12, and 16 hours after the morning dose on Day 1; and prior to dose on Day 2 (24 hours after Day 1 dose)
Blood samples were collected immediately prior to morning dose (time 0 hours); 2, 4, 8, 12, and 16 hours after the morning dose on Day 1; and prior to dose on Day 2 (24 hours after Day 1 dose). The samples were analyzed for the concentration of ABT-333 using validated analytical methods. The time to maximum plasma concentration (Tmax; measured in hours) is the time it takes for a drug to achieve Cmax. The Tmax of ABT-333 was estimated using non-compartmental methods and data are reported as the mean ± standard deviation.
Area Under the Plasma Concentration-time Curve From 0 to 12 Hours (AUC12) Post-dose of ABT-333
时间窗: Immediately prior to morning dose (time 0 hours) and at 2, 4, 8, and 12 hours after the morning dose on Day 1
Blood samples were collected immediately prior to morning dose (time 0 hours) and at 2, 4, 8, and 12 hours after the morning dose on Day 1. The samples were analyzed for the concentration of ABT-333 using validated analytical methods. The area under the plasma concentration-time curve (AUC; measured in ng\*hr/mL) is a method of measurement to determine the total exposure of a drug in blood plasma. The AUC12 of ABT-333 was estimated using non-compartmental methods and data are reported as the mean ± standard deviation.
