Reintroduction of patients into a HCV infection care pathway after a positive chronic hepatitis C diagnosis by previous testing in our hospital who were lost in follow-up. Gaining insight in the possible reasons why patients are lost in follow-up after positive hepatitis C serology.
NCT06718530
Hepatitis C virus (HCV), which infects more than 185 million people, is a major risk factor. Direct-acting antiviral (DAA) therapy has significantly improved the eradication of the virus, but has not completely eliminated the risk of HCC, so careful surveillance is necessary. The genetic diversity of the natural killer receptor, histocompatibility antigens (HLA) and interferon lambda 4 (INFL4) activity, among other factors, have been found to be crucial in directing disease progression. Importantly, these markers are detectable years before the diagnosis of HCC. In addition, polymorphic variants attributable to the expression of genes involved in innate-type immune response, such as IFNL4 and HLA-E, have been shown to be predictive for the development of HCC and have not yet been extensively studied. The aim of the study is to evaluate novel circulating biomarkers, including the presence of antibodies to specific HCV proteome peptides, IFNL4 expression, and the interaction of specific HLA receptors/ligands in a large cohort of HCV-positive subjects in order to create a screening strategy for the early diagnosis of HCV-associated HCC. Part of the study will be devoted to describing the immune microenvironment associated with the expression of IFNL4 and HLAE, evaluating them as potential prognostic indicators for HCC in HCV-infected subjects undergoing surgery for HCC, as well as in those with advanced/metastatic HCC.
NCT05071261
The aim of this study is to assess the HCV screening rate in Arizona by identification of potential HCV patients/subjects through different methods of communication - text message, email, social media, radio, newspaper ads, and flyers.

NCT04852614
This is a prospective, observational, open-label, pharmacokinetic study will evaluate PK of SOF/DAC in lactating HCV-infected females at weaning or women who voluntarily decided to forego breastfeeding to initiate HCV infection treatment. Therefore, drug concentrations can be determined in maternal plasma and milk without risk to the children. HCV infected women at weaning after various durations of breastfeeding and HCV infected women who wish to initiate treatment immediately after delivery and forego breastfeeding will be recruited to start treatment under the guidance of their physician with SOF/DAC to determine M/P ratios of each of SOF, GS-331007 and DAC.
NCT04596475
This trial will be done in participants who undergo transplantation of heart, kidney or lung at University of California, San Diego (UCSD) and receive a hepatitis C infected donor organ. In this trial, the plan is to start hepatitis C treatment just before transplant surgery and treat for a short one-week course to see if hepatitis C infection can be prevented in the transplant recipient. The plan is to perform this trial in 10 participants and if successful, the next step is to try to make it standard of care as prevention of infection is better than treating hepatitis C after discharge from transplant surgery (which is usually a 12 week standard treatment).
NCT05361603

NCT02939989
The purpose of this study was to evaluate the efficacy and safety of co-administration of glecaprevir (ABT-493)/pibrentasvir (ABT 530) plus sofosbuvir (SOF) plus ribavirin (RBV) in hepatitis C virus (HCV) genotype (GT) 1 - 6-infected participants (including non-cirrhotic, or cirrhotic with compensated cirrhosis participants) who had experienced virologic failure in an AbbVie parent clinical study.
NCT04112303
The primary objectives of this study are to evaluate the antiviral efficacy, safety, and tolerability of therapy with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) in adults with chronic hepatitis C virus (HCV) infection and compensated cirrhosis.
NCT04251572
The primary aim of this study is to calculate the incidence of HCV reinfection after successful DAA treatment among people who have recently injected drugs. The secondary aim is to identify factors associated with reinfection in this population. Individuals with active injecting drug abuse with a chronic HCV infection who have achieved end of treatment response (ETR; defined as non-detectable HCV RNA at end of treatment) to any interferon-free DAA combination will be included in this multicenter interventional study.
NCT04136405
This study investigates hepatitis C virus (HCV) outbreak in South West general population in Burkina Faso with three specific objectives: estimate HCV prevalence in South West Region general population in 2019; identify factors associated with recent HCV infection (in subjects younger than 20 years); and evaluate the pilot treatment strategy implemented by the national program for diagnosed cases during investigation.
NCT04768517
Chronic hepatitis C virus (HCV) infection remains a health burden in people living with human immunodeficiency virus (HIV). Interferon (IFN)-based therapy is the treatment of choice for HCV infection for HIV coinfected patients in earlier years. However, the treatment responses are far from ideal and the treatment-emergent adverse events (AEs) are frequently encountered. Based on the excellent efficacy and safety, IFN-free direct acting antivirals (DAAs) have been the mainstay of therapy for HCV. Furthermore, the world health organization (WHO) has set the goal of global HCV elimination by 2030. The microelimination of HCV among HIV/HCV-coinfected patients is also listed as the prioritized target by WHO. Although the overall treatment response has improved dramatically during the past 5-10 years, several studies have indicated the HIV/HCV-coinfected patients had high risks of reinfection following successful antiviral treatment. The risk of HCV reinfection was reported to be 24.6% among HIV-positive men who have sex with men (MSM) in Austria, German, France and the United Kingdom who attained sustained virologic response (SVR) by IFN-based therapy. Two recent studies from Canada showed that the incidence of HCV reinfection in HIV-positive patients was higher that HIV-negative patients (3.44 vs. 1.13 per 100 person-year; 2.56 vs. 1.12 per 100 person-year). In Taiwan, 14.1% of the HIV-positive patients had HCV reinfection following treatment-induced or spontaneous viral clearance, resulting an incidence of 8.2 per 100 person-year with a total of 218.3 person-years of follow-up for these patients. Because data regarding to the HCV reinfection in HIV-positive patients are still limited, where a more comprehensive assessment of HCV reinfection is important based on the perspectives of HCV microelimination among HIV-positive patients in Taiwan, the investigators thus aim to conduct a long-term, large-scale cohort study to assess the risk of HCV reinfection in HIV-positive patients achieving SVR after IFN-based or IFN-free therapies, and to assess the factors associated with different risks of reinfection in these patients.
NCT04732832
Among the hemodialysis units, the global incidence of HCV infection ranges from 1.2% to 2.9%. Data regarding the long-term risk of reinfection among hemodialysis patients achieving SVR are limited. To our best knowledge, only one study assessed the long-term negativity of serum HCV RNA in hemodialysis patients who achieved SVR after IFN-based therapies. With a median follow-up of 48 months following SVR, the life-time cumulative survival for HCV RNA negativity was 86% among the 121 participants who were on maintenance dialysis. Furthermore, the life-time cumulative survival for HCV RNA negativity was 95% among the 45 participants who underwent renal transplantation from HCV-negative donors. Because the literatures regarding the long-term follow-up of viral outcome, the patient numbers to be recruited are still limited, and all studies are focused on IFN-based treatment, we aim to assess the long-term risk of HCV reinfection in hemodialysis patients attaining SVR by IFN-based or IFN-free therapies.
NCT03820258
The primary objective of this study is to evaluate the steady-state pharmacokinetics (PK) and confirm the age-appropriate dose of sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) fixed-dose combination (FDC) in pediatric participants with chronic hepatitis C virus (HCV) infection.
NCT01080222
The purpose of this study is to assess the safety and efficacy of combination treatment with VX-222 and telaprevir administered for 12 weeks with and without peginterferon-alfa-2a and/or ribavirin. The subjects enrolled in this study are chronically infected with hepatitis C virus (HCV) genotype 1 and will not have previously received treatment for their HCV infection. This study will include an Investigational Phase and Extension Phase. These phases will contain a Treatment Period and a Follow-up Period. All subjects will be enrolled in the Investigational Phase of this study. Subjects who fail treatment during the Investigational Phase will have the option to enter the Extension Phase at which point they will be eligible to receive peginterferon alfa-2a and ribavirin for a total of 48 weeks. Based on an evaluation of on-treatment safety, pharmacokinetic and antiviral data from patients in each arm of the trial, Vertex may elect to enroll up to two additional treatment arms (Treatment Arm E and Treatment Arm F) that will evaluate telaprevir/VX-222-based combination therapy. The components of the treatment regimens of these arms will be selected based on clinical data that emerges from the four initially-studied regimens. If enacted, up to 25 patients are expected to enroll in each additional treatment arm. If Treatment Arm E or Treatment Arm F is discontinued subjects meeting certain criteria will have the option to enter a telaprevir-containing Rollover Phase. Subjects who do not meet the eligibility criteria to enter the Rollover Phase may elect to enter the Extension Phase.
