The goal of this non-randomised, quasi-experimental, prospective comparative trial is to trial simplified care pathways for hepatitis C testing and treatment for people who inject drugs in Armenia, Georgia, and Tanzania.
The main questions it aims to answer are:
Participants will:
Researchers will compare cure and participant retention rates between the two groups.
The investigators will conduct a study to trial a new, simplified, and lower cost clinical pathway and determine its feasibility, effectiveness, cost-effectiveness and acceptability in Armenia, Georgia, and Tanzania.
This is a non-randomised, quasi-experimental, prospective comparative trial with approximately 350 participants initiated onto hepatitis C treatment in each arm. Arm one is a simplified care model (following global guidance) with hepatitis C treatment commencing after a rapid hepatitis C antibody test and a confirmatory positive hepatitis C ribonucleic acid (RNA) test. Arm two will involve same day treatment commencement following a positive rapid antibody test without confirmatory RNA testing prior to treatment initiation (RNA testing will be completed after treatment is provided). In arm two, the decision to treat will be based on the result of an early read time (< 5 mins) of a rapid antibody test which previous research findings suggest correlates strongly with a hepatitis C RNA positive test result. All positive participants will be treated with sofosbuvir (400mg) and velpatasvir (100mg), self-administered orally once per day for 12 weeks. Hepatitis C cure will be assessed by sustained virological response (SVR) laboratory testing.
The first primary outcome is feasibility, measured throughout the care cascade. Primary outcomes compared across the two arms will be the proportion of participants 1) commencing treatment and 2) achieving SVR. Test concordance and validity of the early read time will be assessed against laboratory RNA test results (which will also guide decisions to continue or cease treatment in Arm 2). A mixed effects model will be used to assess study outcomes and infectious diseases modelling will determine cost-effectiveness. The acceptability and feasibility of the models will be assessed through thematic analysis of participant and practitioner interviews, and site assessments.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Arm 1 - simplified care model | Active Comparator | Arm 1 will receive DAA medication at the second appointment following the return of RNA HCV results. They will receive sofosbuvir (400mg) and velpatasvir (100mg). |
|
| Arm 2 - short read time | Experimental | Arm 2 will begin DAA treatment after the first appointment following a shortened RDT read time of 5 minutes rather than 20 minutes. They will receive sofosbuvir (400mg) and velpatasvir (100mg). |
