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 subjects with a Sustained Virological Response at 24 weeks after the end of therapy. [ Time Frame: 42 weeks ]

Secondary Outcome Measures :
  1. The proportion of subjects with undetectable HCV RNA levels at end of treatment. [ Time Frame: 18 weeks ]
  2. The proportion of subjects with a Sustained Virological Response at 12 and 48 weeks after the end of therapy. [ Time Frame: 66 Weeks ]
  3. Change in HCV RNA levels from baseline throughout the study. [ Time Frame: 66 Weeks ]
  4. The proportion of subjects who experience virological failure throughout the study. [ Time Frame: 66 Weeks ]

Other Outcome Measures:
  1. Viral resistance analysis at baseline and throughout the study. [ Time Frame: 66 Weeks ]
    The miR-122 seed sites in HCV RNA from subjects at baseline and following viral breakthrough or relapse will be subjected to genotypic sequence analysis.

  2. Plasma pharmacokinetics (AUC, Cmax, tmax) for miravirsen, telaprevir, and ribavirin levels will be determined. [ Time Frame: 31 Weeks ]
    A single sample will be collected at select study visits for all subjects through Week 31. A subset of subjects will participate in extended PK sampling for up to 5 hours at select study visits and for up to 24 hours after the last dose of miravirsen.

  3. Urine pharmacokinetics for miravirsen levels will be determined. [ Time Frame: Up to 16 Weeks ]
    Urine pharmacokinetics (AUC, Cmax, tmax) for miravirsen levels will be measured in a subset of subjects for up to 24 hours after the last dose of miravirsen.
