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 12 Weeks After Discontinuation of Therapy (SVR12) [ Time Frame: Posttreatment Week 12 ]
    SVR12 is defined as HCV RNA < lower limit of quantification (LLOQ) at 12 weeks after stopping study treatment.

  2. Percentage of Participants With Adverse Events Leading to Permanent Discontinuation of Study Drug(s) [ Time Frame: Up to 24 weeks plus 30 days ]

Secondary Outcome Measures :
  1. Percentage of Participants With HCV RNA < LLOQ (15 IU/mL) While on Treatment [ Time Frame: Weeks 1 and 2 ]
  2. Percentage of Participants With HCV RNA < LLOQ (15 IU/mL) While on Treatment [ Time Frame: Weeks 4, 6, and 8 ]
  3. Percentage of Participants With HCV RNA < LLOQ (15 IU/mL) While on Treatment [ Time Frame: Week 10 ]
  4. Percentage of Participants With HCV RNA < LLOQ (15 IU/mL) While on Treatment [ Time Frame: Week 12 ]
  5. Percentage of Participants With HCV RNA < LLOQ (15 IU/mL) While on Treatment [ Time Frame: Weeks 16, 20, and 24 ]
  6. Percentage of Participants With HCV RNA < LLOQ (15 IU/mL) at 2, 4, 8, and 24 Weeks After Discontinuation of Therapy (SVR2, SVR4, SVR8, and SVR 24) [ Time Frame: Posttreatment Weeks 2, 4, 8, and 24 ]
  7. For Cohort 6, Percentage of Participants With HCV RNA < LLOQ (15 IU/mL) at 16 and 20 Weeks After Discontinuation of Therapy (SVR16 and SVR 20) [ Time Frame: Posttreatment Weeks 16 and 20 ]
  8. Percentage of Participants With On-treatment Virologic Failure [ Time Frame: Up to Posttreatment Week 24 ]

    On-treatment virologic failure was defined as:

    • Breakthrough (confirmed HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ 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 8 weeks of treatment)

  9. Percentage of Participants Experiencing Viral Relapse [ Time Frame: Up to Posttreatment Week 24 ]
    Viral relapse is defined as 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.
