Primary Outcome Measures:
  • Percentage of Participants With Sustained Virologic Response 24 Weeks After Treatment (SVR24) [ Time Frame: 24 weeks after last dose of study drug ] [ Designated as safety issue: No ]
    The percentage of participants with SVR24 (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ] 24 weeks after the last dose of study drug). The LLOQ for the assay was 25 IU/mL.

  • Number of Participants With Adverse Events (AEs) [ Time Frame: TEAEs: up to 16 weeks for the 12-week treatment groups and up to 28 weeks for the 24-week treatment groups; SAEs: up to 65 weeks for the 12-week treatment groups and up to 77 weeks for the 24-week treatment groups. ] [ Designated as safety issue: Yes ]
    An AE is any untoward medical occurrence, which does not necessarily have a causal relationship with treatment. A serious adverse event (SAE) is an AE that results in death, is life-threatening, results in or prolongs hospitalization, results in congenital anomaly, persistent or significant disability/incapacity, spontaneous or elective abortion, or requires intervention to prevent a serious outcome. AEs were rated for severity as either Mild: transient and easily tolerated; Moderate: causes discomfort and interrupts usual activities; or Severe: causes considerable interference with usual activities, may be incapacitating or life-threatening. AEs related to study drug were assessed as being either probably or possibly related by the investigator. Treatment-emergent AEs (TEAEs) were collected from the first dose of study drug administration to 30 days after last dose; SAEs were collected from the time that informed consent was obtained to 30 days after last dose.


Secondary Outcome Measures:
  • Percentage of Participants With Sustained Virologic Response 12 Weeks After Treatment (SVR12) [ Time Frame: 12 weeks after last dose of study drug ] [ Designated as safety issue: No ]
    The percentage of participants with SVR12 (plasma HCV RNA level < LLOQ 12 weeks after the last dose of study drug). The LLOQ for the assay was 25 IU/mL.

  • Percentage of Participants With End of Treatment (EOT) Response [ Time Frame: 12 or 24 weeks after first dose of study drug ] [ Designated as safety issue: No ]
    The percentage of participants with EOT response (plasma HCV RNA level < LLOQ at week 12 for the 12-week duration arms and Week 24 for the 24-week duration arms12). The LLOQ for the assay was 25 IU/mL.

Detailed Description:
This multicenter, randomized, open-label, parallel-arm, combination treatment study consisted of a Treatment and Post-treatment Phase, divided into 2 cohorts: 1) chronic HCV GT1b- infected, pegIFN/RBV treatment-exposed Japanese adults; and 2) HCV GT2-infected, pegIFN/RBV treatment-exposed Japanese adults. The Treatment Phase evaluated the antiviral activity, safety, and pharmacokinetics of a range of ABT-450/r and ABT-267 doses for 12 to 24 weeks. The Post-treatment Phase evaluated the evolution and persistence of viral resistance to ABT-267 and ABT-450.
