Program of Screening, Prevention and Elimination of Hepatitis C in Penitentiary Institutions in Cantabria (JAILFREE-C)

Study Overview
=================
Brief Summary
-----------------
The objectives of this study are: To perform a systematic screening and evaluation of the prevalence of infection by hepatitis C virus (HCV), hepatitis B virus (HBV) and human immunodeficiency virus (HIV) in the prison population. To perform an adequate characterization of patients and the characteristics of HCV infection in this population. To evaluate the effectiveness and security in the prison population of an interferon-free antiviral regimen. To evaluate the impact of a strategy of systematic HCV treatment on the rates of persistent infection, reinfection and super-infection in a prison population, in the short, medium and long term.

Detailed Description
-----------------
Background: Infections caused by hepatitis B, C and HIV viruses represent a serious health problem. The inmate population represents a reservoir with high prevalence of these kind of infections. The completion of a secondary prevention through early detection of infections in early stages, and tertiary prevention by treatment of diagnosed cases, constitutes one of the pillars of the approach to these diseases. This strategy is even more valuable in the inmate population because it can help eliminate a source of spread of these diseases in addition to relieving the burden of disease in this population. In this regard, one of the mandates of the recently adopted National Strategy Plan for the Hepatitis C in Spain emphasizes these strategies. Finally, a program of this nature is intended as a pilot experience that could be extended to other prison communities at national and European level. Endpoints - To estimate the prevalence of HBV, HCV and HIV in the inmate population of El Dueso. - To perform a systematic treatment of the inmate population against HCV infection. The treatment will be directed to both, the prevalent population and the new prisoners who enter the prison. The other detected infections will be also treated accordingly. - To carry out a descriptive evaluation of the efficacy and safety of an interferon-free regimen against the HCV infection in this population. This regimen will be mainly based on Sofosbuvir and ledipasvir (± RBV) according to the current clinical practice adopted in the National Strategy Plan for the Hepatitis C. - To evaluate the rates of persistent infection, reinfection and super-infection as defined. Projected Study Design The present study is divided in two parts. A transversal and observational one of epidemiological basis aimed to determine the prevalence of viral infections by hepatitis B and C viruses and also by HIV in the inmate population. In a second prospective phase of follow-up, a systematic treatment of the infected cohort will be carried out in accordance with the current clinical practice adopted in the National Strategy Plan for the Hepatitis C. Data on efficacy, safety and quality of life will be collected throughout the study. Finally, an evaluation of the rates of persistent infection, reinfection and super-infection will be also recorded. Treatment of new admissions throughout the study periods is also contemplated. Patients and Methods: Patients: - Epidemiological transversal phase: 435 subjects (the whole inmate population) will be included. - Prospective observational phase: 120 infected patients (taking into account a reported chronic HCV infection prevalence of 20% in the inmate population -data from the latest National Strategic Plan for addressing hepatitis C in the National Health Service NHS 2015-) and that it is intended to treat newly infected inmate who enter in prison during the two years of study. Endpoints: Primary endpoint: Sustained Virological Response (SVR) at 12 weeks after the end of treatment. Secondary outcomes: SVR at 4 weeks, Safety issues, Quality of life, Serum prevalence of chronic HCV, HBV infection; re-infection/superinfection rates; cost-effectiveness Variables: Variables: HCV status by ELISA; Viral load (PCR) HCV IU / ml (primary), treatment type and duration, serological status of HBV infection; liver stiffness through Fibroscan. QoL variables, ultrasonographic variables. phylogenetic analysis of HCV genome in cases of non-response. costs Projected Number of Sites (if additional sites, please specify) 1 (El Dueso Penitentiary Centre) Participating Countries 1 (Spain) Anticipated First Patient In 2-1-2016 Projected Duration of Enrollment 1 month for the prevalent inmate population. The entry of subjets (new inmates) will be open throughout the study Projected Duration of Treatment 6 month (8-24 weeks according to patient and virological characteristics). Study Duration 31 months (1 month enrollment + 6 months of treatment + 24 months observation and final evaluation of reinfections)
