A Collaborative Trial in Injectors of Individualized Treatment for Genotype 2/3
A Collaborative Trial in Injectors of Individualized Treatment for Genotype 2/3
This sudy will determine whether shortening treatment for hepatitis C is feasible, safe and
 effective for patients who are current injection drug users or receiving opiate substitution
 therapy and who are responding well to treatment early on.
The study will evaluate the feasibility, safety and effectiveness of shortened treatment for
 hepatitis C genotypes 2/3 in current injection drug users or receiving opiate substitution
 therapy. Treatment will be with pegylated interferon alfa 2b (directly observed) and
 ribavirin for 12 weeks in those that have non-quantifiable (<15 IU/ml detected and <15 IU/ml
 undetected) HCV RNA or undetectable HCV RNA on qualitative assay at week 4 and 24 weeks in
 those that have quantifiable (≥15 IU/ml) HCV RNA or detectable HCV RNA on qualitative assay
 at week 4.
Inclusion Criteria:

 -  18 years of age

 -  chronic HCV infection

 -  HCV genotype 2/3 infection

 -  active injection drug use (within 24 weeks prior to consent) or currently receiving
 opiate substitution therapy

 -  compensated liver disease

 -  negative pregnancy test (within 24 hours of first dose of study medication)

 -  effective contraception for the duration of the study

 -  written informed consent

 Exclusion Criteria:

 -  previous interferon or ribavirin therapy

 -  investigation drug use in the 6 weeks prior to first dose of study medication

 -  infection with HCV genotypes other than 2/3

 -  HIV infection

 -  HBV infection

 -  ongoing severe psychiatric disease

 -  frequent drug use that is judged by the treating physician to compromise treatment
 safety

 -  standard clinical and medical exclusions for treatment with pegylated interferon alfa
 2b and ribavirin
