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. the proportion of patients achieving sustained viral response (SVR) [ Time Frame: 12 weeks after the end of treatment ]

Secondary Outcome Measures :
  1. Proportion of patients with "virologic relapse" post-treatment, defined as confirmed and quantifiable (>LLOQ) serum HCV RNA in a patient who achieved non-detectable serum HCV RNA by the end of treatment [ Time Frame: up to 24 weeks post-treatment ]
  2. Proportion of patients with confirmed viral breakthrough during study treatment [ Time Frame: up to 12 weeks of study treatment ]
    "Confirmed viral breakthrough" is defined as a > 1 log increase in HCV RNA from post-Baseline nadir value or confirmed increase in HCV RNA ≥LLOQ if HCV RNA previously declined to <LLOQ (detected or not detected), during the 12-week study treatment period

  3. Proportions of study participants who receive at least one dose of study drug and who prematurely discontinue study treatment, and proportions prematurely discontinuing treatment for clinical adverse events or laboratory abnormalities [ Time Frame: up to 12 weeks of study treatment ]
  4. Proportions of study participants experiencing treatment-emergent adverse events (serious and non-serious) considered to be possibly or probably attributable to study treatment, overall and by body system [ Time Frame: up to 12 weeks of study treatment ]
