Summary

Hepatitis C is a blood borne virus that can seriously damage the liver. An estimated 50,000 Scots have been infected with Hepatitis C virus (HCV). The main driver for spread of HCV infection is intravenous drug use. As HCV is highly infectious by the blood borne route through needle sharing, it can infect the person who injects drugs (PWID) early in their habit.

Around two thirds of people who are infected are unaware of it, and often show no symptoms over a long period of time. While there is presently no vaccination for Hepatitis C, improved treatments with shorter duration are now available. This raises the possibility of using therapy as prevention, turning the epidemic off at source, by targeting active PWID who are the main source of new infections. Modelling work illustrates the startling possibility and impact of treating drug users to reduce the prevalence of HCV.

The focus of this trial will be to ascertain whether oral treatment regimens are effective in the treatment as prevention scenario in an active PWID population where illicit drug taking and poor adherence may reduce treatment efficacy. The investigators will trial 3 different methods of delivering treatment and will trial an unlicensed combined treatment against HCV genotype 3 infection of shortened duration since current regimens for this genotype are limited.

The investigators will recruit 135 participants and randomise them to one of three arms: daily, directly observed therapy; fortnightly dispensing of drugs; fortnightly dispensing of drugs with a psychological adherence intervention. Randomisation will be stratified according to HCV genotype. Participants will be treated for 12 or 8 weeks depending on genotype and followed up 12 weeks post treatment for the measurement of sustained viral response (SVR). The primary outcome measure will be SVR at 12 weeks post treatment (SVR12), as this measure of cure is the determinant of sufficient compliance and efficacy within the 3 treatment arms. Analysis will be by modified intention to treat of all participants who receive one dose of therapy, to show non-inferiority fortnightly dispensing is easier to deliver than daily dispensing.

Conditions

  • Hepatitis C

Interventions

DRUG

Elbasvir/Grazoprevir 50 MG-100 MG Oral Tablet

Drugs will be given to participants to treat hepatitis C infection

BEHAVIORAL

Psychological intervention

Participants randomised to fortnightly pick-up with psychological intervention will have an interview with the study nurse designed to aid their compliance with the drug regimen. During the intervention participants will be guided by their trial nurse in the completion of a personalised booklet, "Hepatitis C and Me". The booklet uses the principles of node-link mapping to structure the intervention.

DRUG

Sofosbuvir 400 MG

Drugs will be given along with Zepatier to participants to treat genotype 3hepatitis C infection
