About this study

Official title: A Pilot Study to Assess the Feasibility of Hepatitis C Virus (HCV) Treatment as Prevention With Interferon-free Direct Acting Antivirals (DAAs) in the Prison Setting

The purpose of the study is to assess how feasible it is to treat and prevent the transmission of Hepatitis C in the prison setting to achieve substantial reductions in the incidence and prevalence of Hepatitis C.

It is hypothesised that a rapid scale-up of Hepatitis C Virus (HCV) treatment with interferon-free Direct Acting Anti-virals (DAAs) in prison inmates will achieve a >50% reduction in the incidence of HCV infection over a two year period in the prison setting.

Read the detailed description

The study will be conducted initially in two maximum security prisons located in New South Wales, Australia and comprises four phases:

Phase 1, Surveillance of HCV Incidence and Prevalence and Liver Disease Burden:

The HCV incidence and prevalence phase is a prospective longitudinal cohort. HCV incidence and prevalence and liver disease burden will be monitored through regular six-monthly cross-sectional surveys of participants for 3.5 years.

Phase 2, Modelling:

The data from year 1 of the surveillance of HCV incidence and prevalence phase will be used to model the number of participants required to be treated to demonstrate a 50% reduction in incidence.

Phase 3, Treatment Intervention:

The treatment intervention will only be conducted in one of the maximum security prisons (Treatment Prison). The second prison will continue to care for HCV infected inmates as per standard of care (Control Prison). The intervention component of this study will consist of a phase IV open-label study of interferon-free DAAs for the treatment of HCV infection. The treatment phase will commence in year 2 and will be two years in duration. The exact drug combination and regimen to be used in the treatment intervention will be determined in year 1 once phase II and III data of sofosbuvir and ledipasvir and other potential interferon-free DAA regimens are published. The exact number of participants required to demonstrate a 50% reduction in incidence will be determined during the modelling phase.

Phase 4, Cost-effectiveness:

During the treatment intervention phase participants will be required to complete a survey to obtain estimates of health outcomes (EQ-5D survey) at regular intervals. This data will be used by the health economist to determine the cost effectiveness of treatment as prevention in the prison setting.

    Measured: 12 weeks

  6. Number of patients with adverse events

    Safety and tolerability of the treatment regimen

    Measured: 16 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Sofosbuvir/velpatasvir in people with Hepatitis C, run by Kirby Institute at 4 sites in Australia.

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 0 inclusion and 50 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 9 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Australia. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Hepatitis C virus (HCV) incidence (time frame: 2 years). 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 NCT02064049, which also lists 3 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.

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 9 Dec 2019.
