Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
Miravirsen sodium
Arm Description
Miravirsen will be dosed as single subcutaneous injections. Subjects will receive 5 weekly doses at 7 mg/kg then 4 every other week doses at 5 mg/kg.
Outcomes
Primary Outcome Measures
The proportion of subjects with sustained virological response 24 weeks after the end of therapy.
Secondary Outcome Measures
The proportion of subjects with a sustained virological response 12 and 48 weeks after the end of therapy.
The proportion of subjects with undetectable HCV RNA levels at the end of treatment.
Change in HCV RNA levels from baseline throughout the study.
The proportion of subjects who experience virological failure throughout the study.
Safety will be assessed by evaluation of adverse events, physical examinations, vital signs, 12-lead ECGs, and laboratory assessments (clinical chemistry, hematology, urinalysis).

5. Study Description
Brief Summary
The purpose of this open-label study is to assess the safety, antiviral activity, and pharmacokinetics of 9 subcutaneous injections of miravirsen monotherapy (5 weekly doses over 5 weeks, followed by a further 4 doses once every other week over 7 weeks) over a total of 12 weeks of treatment. The subjects enrolled in this study are chronically infected with HCV genotype 1 and are null responders to treatment with peg IFNα/RBV therapy.
