Trial 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. Read more about this study

About this study

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

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

    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.

  • standard DOT (PEG-DOT control arm)Other

    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 is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adherence

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

    Measured: 24 -48 weeks

Secondary outcomes (3)
  1. sustained viral response (SVR)

    Measured: 24 weeks after treatment completion

  2. end of treatment response (ETR)

    Measured: 24 - 48 weeks

  3. treatment completion

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

    Measured: 24 - 48 weeks

Questions about this trial

What is this clinical trial studying?

A study testing enhanced DOT (both pegylated interferon alfa-2a and ribavirin) in people with Hepatitis C and Medication Adherence, run by Albert Einstein College of Medicine at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adherence (time frame: 24 -48 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01442311, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jun 2015.
