Increasing Access to Hepatitis C Treatment in Opioid Endemic Rural Areas: the Kentucky Viral Hepatitis Treatment (KeY Treat) Study

The overarching goal of the Kentucky Viral Hepatitis Treatment Project (KeY Treat) is to increase access to treatment for the hepatitis C virus (HCV) in a rural Appalachian community in the midst of the opioid/HCV syndemic. This study seeks to examine whether removing barriers associated with accessing direct-acting antivirals (DAAs) for the treatment of HCV (high out-of-pocket costs, insurance restrictions requiring a specialist, abstinence, and significant liver damage) will significantly reduce the burden of HCV in Perry County, Kentucky. Stated in its most simplistic terms, the research question asks, gIf you build it, will they come?h The proposed study is made possible by a significant drug donation from Gilead Sciences for sofosbuvir/velpatasvir, a 12-week, once per day, pan-genotypic DAA. KeY Treat proposes a multi-pronged approach to treating HCV using a mid-level provider model. In addition to DAA treatment, participants will be offered access to subsidized substance abuse treatment services with medication-assisted treatment, syringe services, and case management. We will leverage existing resources in the target community (public health, jail, hospital), as well as ongoing projects dedicated to increasing access to HCV care in affected communities (ECHO, FOCUS) to answer whether removing the major barriers to HCV treatment affect access, and what barriers remain. All RNA-positive residents of Perry County, Kentucky will be eligible/recruited for study participation (N.1,000), and the following specific aims will be addressed: 1) determination of HCV treatment uptake among rural residents with chronic HCV; 2) examination of the predictors of treatment completion among those enrolled in KeY Treat; 3) examination of the characteristics of participants achieving sustained virologic response (SVR, or cure); 4) establishment of long-term re-infection rates among those achieving SVR; and 5) examination of 5-year reductions in incidence and prevalence of HCV in the intervention community compared with a control county in rural Kentucky. The proposed research has tremendous potential to impact public health in the rural United States. The majority of counties identified in CDCfs recent HCV/HIV hotspot analysis were rural, and there is a real need to improve access to DAAs in order to prevent further HCV transmission, reduce the burden of advanced liver disease, and hepatocellular carcinoma in generations to come. Data from KeY Treat will inform policies around Medicaid/insurance restrictions for DAAs, and will deliver a much needed blueprint for the provision of HCV treatment in resource-deprived rural areas.
