Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Cessation of Therapy (SVR12) [ Time Frame: Posttreatment Week 12 ]
    SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ) at 12 weeks after stopping study treatment.

  2. Percentage of Participants Who Prematurely Discontinued Study Drug Due to Any Adverse Event [ Time Frame: Up to 12 weeks ]

Secondary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response 4 Weeks After Cessation of Therapy (SVR4) [ Time Frame: Posttreatment Week 4 ]
    SVR4 was defined as HCV RNA < LLOQ at 4 weeks after stopping study treatment.

  2. Percentage of Participants With HCV RNA < LLOQ at Week 2 [ Time Frame: Week 2 ]
  3. Percentage of Participants With HCV RNA < LLOQ at Week 4 [ Time Frame: Week 4 ]
  4. Percentage of Participants With HCV RNA < LLOQ at Week 8 [ Time Frame: Week 8 ]
  5. Percentage of Participants With HCV RNA < LLOQ at Week 12 [ Time Frame: Week 12 ]
  6. HCV RNA at Week 2 [ Time Frame: Week 2 ]
  7. HCV RNA at Week 4 [ Time Frame: Week 4 ]
  8. HCV RNA at Week 8 [ Time Frame: Week 8 ]
  9. HCV RNA at Week 12 [ Time Frame: Week 12 ]
  10. Change From Baseline in HCV RNA at Week 2 [ Time Frame: Baseline; Week 2 ]
  11. Change From Baseline in HCV RNA at Week 4 [ Time Frame: Baseline; Week 4 ]
  12. Change From Baseline in HCV RNA at Week 8 [ Time Frame: Baseline; Week 8 ]
  13. Change From Baseline in HCV RNA at Week 12 [ Time Frame: Baseline; Week 12 ]
  14. Percentage of Participants With Virologic Failure [ Time Frame: Up to Posttreatment Week 12 ]

    Virologic failure was defined as

    On-treatment virologic failure:

    • Breakthrough (confirmed HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ on 2 consecutive measurements while on treatment), or
    • Rebound (confirmed > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment), or
    • Non-response (HCV RNA persistently ≥ LLOQ through 12 weeks of treatment)

    Virologic relapse:

    • HCV RNA ≥ LLOQ during the post-treatment period having achieved HCV RNA < LLOQ at end of treatment, confirmed with 2 consecutive values or last available post-treatment measurement
