Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Drug users account for a disproportionately large burden of hepatitis C virus (HCV) infection. However, HCV treatment adherence rates in drug users may be suboptimal in patients who use drugs regularly during HCV treatment. Because HCV treatment is most effective when patients adhere to at least 80% of the prescribed treatment regimen, interventions to improve HCV treatment adherence need to be developed and evaluated. The investigators designed the HCV DOT trial to test the efficacy of two versions of modified directly observed HCV therapy provided on-site at a methadone clinic. The primary objective of this trial is to determine whether enhanced DOT with both pegylated interferon alfa-2a plus ribavirin (PEG/RBV-DOT) is more efficacious than standard DOT with weekly provider-administered pegylated interferon (PEG-DOT) and self-administered ribavirin for increasing adherence and improving HCV treatment outcomes. The investigators hypothesize that PEG/RBV-DOT is associated with increased adherence and rates of sustained viral response compared with PEG-DOT.
