About this study

Official title: Towards Ending HCV Infection Among Active Drug Users: a Community-based Intervention in Montpellier.

The study aims to assess the effectiveness of a community-based model of HCV mass screening associated with an immediate HCV treatment on the cascade of care among active drug users (DUs) in the city of Montpellier, France.

Read the detailed description

Active DUs will be recruited using a Respondent-Driven Sampling (RDS) method. Hosted in the temporary community care facility (the research site), located outside the existing care facilities in the city, participants will benefit from HCV/HIV/HBV screening, on-site measurement of HCV-RNA and liver fibrosis, early treatment, treatment follow-up and risk and harm reduction tools related to their risk practices. Peers will be present in this unique structure and will accompany participants throughout their treatment. Participants will be referred during treatment to existing care facilities but followed up in the research up to 44 to 48 weeks after initiation of treatment to assess the rate of re-infection. The number of active DUs in the population will be estimated by using a capture/recapture method nested in the RDS survey

Secondary objectives of the research are:

  • To estimate the seroprevalence of hepatitis C in active DUs in Montpellier;
  • To estimate the size of the active DUs population in the city of Montpellier using a capture/recapture method;
  • To estimate HCV care cascade steps in active DUs in Montpellier;
  • To identify the factors associated with HCV treatment failure;
  • To determine the proportion of treated and cured HCV patients who re-infect within months after end of treatment;
  • To estimate the seroprevalence of hepatitis B and HIV infection in active DUs in Montpellier.

What participants receive

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

  • HCV screeningDiagnostic test

    All patients will have HCV screening using rapid tests. HIV and HBV testing will also be conducted and patients will be appropriately referred to appropriate health services.

  • Diagnosis of hepatitis CDiagnostic test

    HCV-RNA assay (GeneXpert, Cepheid) will be performed for all participants with positive HCV serology to determine if patients have chronic hepatitis C (defined by HCV-RNA>10 UI/mL). In addition a measure of the liver stiffness will be performed.

  • HCV treatmentDrug

    Direct-Acting Antiviral drugs will be prescribed for 8 or 12 weeks according to liver assessment.

The record lists 1 site in France. 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?

Proportion of treated and cured DU participants. (time frame: SVR12 (12 weeks after end of HCV treatment)). 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 NCT04008927, which also lists 8 linked publications.

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.
