The Kentucky Viral Hepatitis Treatment Study (KeY Treat)

July 14, 2023 updated by: Jennifer Havens

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 hepatitis C virus (HCV) treatment access and delivery in a rural Appalachian community, which is in the midst of the opioid/hepatitis C (HCV) syndemic. KeY Treat is a clinical research study seeking to determine whether removing barriers (cost, insurance, specialist, abstinence) associated with accessing direct-acting antivirals (DAAs) for the treatment of HCV will impact health in Perry County, Kentucky.

Detailed Description

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. 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 medication-assisted treatment, syringe services, and case management. Existing resources in the target community (public health, jail, hospital) will be leveraged, 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≈900), 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; 5) examination of 5-year reductions in incidence and prevalence of HCV in the intervention community compared with a control county in rural Kentucky; and 6) evaluate the impact and cost-effectiveness of KeY Treat using mathematical modeling. The proposed research has tremendous potential to impact public health in the rural United States. The majority of counties identified in CDC's 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: HCV Positive Study Participants
Study participants will be administered a standard 12-week course of sofosbuvir/velpatasvir (Epclusa®).
The protocol is intended to follow best practices/standard of care for the treatment of HCV, with additional allowances for the investigators to apply rigorous scientific practices for the research aspects of the study. While the treatment of HCV is fairly straightforward, less is known about treating active drug users and RNA-positive individuals in rural areas. We propose eight visits, including intake, four treatment-related visits, and three visits to determine re-infection (6- and 12-months post-SVR). Because determination of medication adherence and long-term reinfection rates are not part of standard clinical practice, the rural protocol developed at the conclusion of KeY Treat will be streamlined based on findings, consisting of five or fewer clinical contacts. The drug used for treatment is Epclusa®, a 12-week, once per day, pan-genotypic DAA with a favorable side effect profile. Vosevi® will also be available in cases where participants are non-responsive or are re-infected.
No Intervention: Control (Pike County)
After completion of the study, we will compare HCV incidence and prevalence rates in Perry County (intervention) and Pike County (control). This will be measured through data provided by the local health departments of each county. Confidential Hepatitis C screening will be conducted in some cases, and resources will be provided to those testing positive but they will not receive treatment as part of this study.
