Brief Summary
The purpose of this study was to assess the safety, pharmacokinetics, and 4-week rapid virologic response (RVR) of 3 different doses of ABT-267 (also known as ombitasvir) in combination with pegylated interferon/ribavirin (pegIFN/RBV) compared with pegIFN/RBV alone (ABT-267 placebo) in treatment naïve, hepatitis C virus (HCV), genotype 1-infected participants.

Outcome Measures
Primary Outcomes (6)
Percentage of Participants With 4-week Rapid Virologic Response (RVR)
Plasma hepatitis C virus ribonucleic acid (HCV RNA) levels (measured in IU/mL) were determined for each sample using a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay. Rapid virologic response was defined as HCV RNA levels \< the lower limit of detection (\< 15 IU/mL) at Week 4. Data are reported as percentage of participants with RVR.
Week 4
Maximum Plasma Concentration (Cmax) of ABT-267
Blood samples were collected immediately prior to morning dose (time 0 hours); 2, 4, 6, and 8 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-267 using validated analytical methods. The maximum plasma concentration (Cmax; measured in ng/mL) is the highest concentration that a drug achieves in the plasma after administration in a dosing interval. The Cmax of ABT-267 was estimated using non-compartmental methods and data are reported as the mean ± standard deviation.
Immediately prior to morning dose (time 0 hours); 2, 4, 6, and 8 hours after the morning dose on Day 1; and prior to dose on Day 2 (24 hours after Day 1 dose)
Time to Maximum Plasma Concentration (Tmax) of ABT-267
Blood samples were collected immediately prior to morning dose (time 0 hours); 2, 4, 6, and 8 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-267 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-267 was estimated using non-compartmental methods and data are reported as the mean ± standard deviation.
Immediately prior to morning dose (time 0 hours); 2, 4, 6, and 8 hours after the morning dose on Day 1; and prior to dose on Day 2 (24 hours after Day 1 dose)
Area Under the Plasma Concentration-time Curve From 0 to 24 Hours (AUC24) Post-dose of ABT-267
Blood samples were collected immediately prior to morning dose (time 0 hours); 2, 4, 6, and 8 hours after the morning dose on Day 1; prior to dose on Day 2 (24 hours after Day 1 dose); and at each subsequent study visit. The samples were analyzed for the concentration of ABT-267 using validated analytical methods. The area under the plasma concentration -time curve (AUC; measured in ng\*hr/mL) is a method of measurement of the total exposure of a drug in blood plasma. The AUC24 of ABT-267 was estimated using non-compartmental methods and data are reported as the mean ± standard deviation.
Immediately prior to morning dose (time 0 hours); 2, 4, 6, and 8 hours after the morning dose on Day 1; prior to dose on Day 2 (24 hours after Day 1 dose); and at each subsequent study visit up to Week 12
Plasma Concentrations of Ribavirin (RBV)
Blood samples were collected at each study visit from Week 1 to Week 12. The samples were analyzed for the concentration of RBV (measured in ng/mL) using validated analytical methods and RBV concentrations in plasma were summarized at each visit. Data are reported as the median (range).
At each study visit from Week 1 to Week 12
Serum Concentrations of Pegylated Interferon (pegIFN)
Blood samples were collected at each study visit from Week 1 to Week 12. The samples were analyzed for the concentration of pegIFN (measured in ng/mL) using validated analytical methods and pegIFN concentrations in serum were summarized at each visit. Data are reported as the median (range).
At each study visit from Week 1 to Week 12

Study Arms (4)
ABT-267 (5 mg) once daily + pegIFN/RBV

EXPERIMENTALParticipants were given 50 mg ABT-267 once daily in combination with pegylated interferon/ribavirin (pegIFN/RBV) for 12 weeks, followed by 36 weeks of pegIFN/RBV treatment alone. Pegylated interferon was dosed 180 µg subcutaneously once a week. Ribavirin was dosed 1000 or 1200 mg daily divided twice a day.

EXPERIMENTALParticipants were given 200 mg ABT-267 once daily in combination with pegylated interferon/ribavirin (pegIFN/RBV) for 12 weeks, followed by 36 weeks of pegIFN/RBV treatment alone. Pegylated interferon was dosed 180 µg subcutaneously once a week. Ribavirin was dosed 1000 or 1200 mg daily divided twice a day.
Placebo + pegIFN/RBV
PLACEBO COMPARATORParticipants were given matching placebo to ABT-267 once daily in combination with pegIFN/RBV for 12 weeks, followed by 36 weeks of pegIFN/RBV treatment alone. Pegylated interferon was dosed 180 µg subcutaneously once a week. Ribavirin was dosed 1000 or 1200 mg daily divided twice a day.
