Study summary

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.

Study arms

  • Experimental
    enhanced DOT (PEG/RBV-DOT)

    Subjects randomized to the PEG/RBV-DOT arm receive weekly provider-administered pegylated interferon alfa-2a injections plus modified directly observed ribavirin therapy. We describe this as modified because ribavirin ingestion is observed at the methadone window three to six days per week based on the participants' methadone pick-up schedule, and only one of two daily doses is observed.

    Other: enhanced DOT (both pegylated interferon alfa-2a and ribavirin)

  • Active comparator
    standard DOT (PEG-DOT)

    Subjects randomized to the Peg-DOT arm receive standard on-site treatment (weekly provider-administered pegylated interferon alfa-2a injections) and self-administered twice-daily oral ribavirin. Subjects in the PEG-DOT arm are dispensed monthly medication bottles of ribavirin, and ingest the ribavirin at home.

    Other: standard DOT (PEG-DOT control arm)

Interventions

  • Otherenhanced DOT (both pegylated interferon alfa-2a and ribavirin)

We describe this as modified because ribavirin ingestion is observed at the methadone window three to six days per week based on the participants' methadone pick-up schedule, and only one of two daily doses is observed.

  • Otherstandard DOT (PEG-DOT control arm)

    Subjects randomized to the Peg-DOT arm receive standard on-site treatment (weekly provider-administered pegylated interferon alfa-2a injections) and self-administered twice-daily oral ribavirin. Subjects in the PEG-DOT arm are dispensed monthly medication bottles of ribavirin, and ingest the ribavirin at home.

What researchers measure

Primary outcomes

  1. Adherence

    Adherence assessed by pill count, self-report, and medical records.

    Time frame: 24 weeks after treatment completion

  2. end of treatment response (ETR)

    Time frame: 24 - 48 weeks

  3. treatment completion

    completion of at least 80% of planned duration of HCV treatment.

    Time frame: 24 - 48 weeks
