Abstract

Objectives The overall goal of the Kentucky Viral Hepatitis Treatment Study (KeY Treat) is to eliminate hepatitis C transmission from a county in Appalachian Kentucky by removing the barriers to accessing hepatitis C virus (HCV) treatment. Methods/analysis KeY Treat is a phase IV, open-label, single-arm clinical trial of sofosbuvir/velpatasvir (SOF/VEL) for the treatment of viraemic HCV infections. Those eligible for KeY Treat are at least 18 years of age, viraemic and are residents of the target county. Pregnant women are not eligible. Rapid HCV RNA screening is used to determine eligibility, and those with a quantifiable viral load (VL) consenting to participate initiate SOF/VEL on the same day. All pharmacologic treatment and related medical care is provided free of charge using a non-specialist provider model. Follow-up visits occur at 2, 6 and 12 weeks during treatment to assess medication adherence (measured via VL and self-report), side effects and engagement in risk behaviours. Post-treatment visits occur at 12 weeks (sustained virologic response (SVR12) visit), 6 months and 12 months post-treatment completion to assess re-infection. A control county has also been identified, and prevalence and incidence of chronic HCV infections will be compared with the target community longitudinally. The primary outcome to assess elimination is SVR12. However, several outcomes will be measured to assess the effectiveness of removing the barriers to HCV treatment, including treatment entry, completion and re-infection. Analyses will be conducted via a generalised linear model framework that can incorporate flexible covariate adjustment and multiple outcome types with a compatible link function. Mathematical modelling will be completed assessing the impact and cost-effectiveness of the intervention. Ethics and dissemination KeY Treat has been approved by the Institutional Review Board at the University of Kentucky. Results from KeY Treat will be presented at conferences and published in peer-reviewed journals. Trial registration number NCT03949764.
