Filter by:This study is an open-label, multi-center trial to evaluate the novel 2-drug regimen of uprifosbuvir (MK-3682) 450 mg and ruzasvir (MK-8408) 60 mg in participants with chronic hepatitis C virus (HCV) genotype (GT)1, GT2, GT3, GT4, GT5, or GT6 infection. The impact of the study treatment regimen on the percentage of participants with undetectable HCV ribonucleic acid [RNA] 12 weeks after completing study treatment (SVR12) will be evaluated.
Hepatitis C virus (HCV) chronic infection affects 200 million people worldwide. HCV antiviral treatment has evolved rapidly since 2011. The use of pegylated interferon (PEG-INF) with ribavirin (RBV) has supposed high serious adverse events (SAEs) and low efficacy, especially in patients with cirrhosis. The introduction of 1st generation protease inhibitors (PIs) in genotype-1 (GT1) HCV, such as boceprevir (BOC) and telaprevir (TVR), improved the efficacy but increased the SAEs. Currently, interferon-free direct-acting antivirals (IF-DAAs) achieve great effectiveness with minimum SAEs. However, studies evaluating efficacy and safety of DAAs in cirrhotic patients are limited in real clinical practice. The aim of our study is to evaluate in HCV-cirrhotic patients the efficacy and safety of 3 treatment strategies (PEG-IFN/RBV, PEG-IFN/RBV/PIs, and IF-DAAs) in routine practice according to European guidelines from 2010 to 2015. The secondary aim is to evaluate the impact of sustained virological response on gastroesophageal varices (GOV).
Follow-up for durability of sustained virologic response, changes in liver function and safety in patients with SVR24 in feeder studies
Counseling intervention: Primary objective: to evaluate and compare, in at-risk populations, the efficacy of three different counseling methods in terms of propensity to come back for a HIV re-test. Secondary objectives: to evaluate and compare the efficacy of the counseling methods in terms of reported risk behavior and HIV knowledge as well as their acceptability and cost-effectiveness; describe the distribution of duration from HIV primary infection to detection; and estimate the prevalence of chronic hepatitis B and C, and syphilis in HIV-uninfected participants of targeted populations. Reminder intervention Primary objective: to evaluate and compare, in at-risk individuals who require frequent testing, the efficacy of reminders in terms of propensity to come back for a HIV re-test within 7 months. Secondary objective: to assess the cost-effectiveness of reminders. The interim analyses have shown that that some strategies are better than the others and the Advisory Committee recommended to use only the most efficient strategies (Computer assisted counseling and Scheduling an appointment and sending reminder to clients). In addition, CD4 cell count normal ranges in 30 HIV uninfected individuals in Thailand will be assessed. Transient elastometry (FibroScan) will be used to assess liver fibrosis in participants with and without viral hepatitis.
This is a Phase 2, open-label,randomized, multiple dose, varied administration regimen study with 2 parts (Parts A and B) in Subjects Infected with Chronic Hepatitis B Virus
The hypothesis of this investigation stresses that the current understanding of the prevalence of HCV infection in the general population and in different subgroups will serve to lay out medium- and long-term measures for action geared toward reducing the disease burden through preventive, research, screening and therapeutic measures. Aim: To determine the prevalence of seropositivity and chronic infection with the HCV and to analyze the associated factors. To analyze and infer different screening strategies for HCV infection based on the at-risk groups/cohorts of elevated prevalence detected. to assess the efficiency of screening strategies and the subsequent cost-effectiveness of treatment in the general population
As HBsAg clearance is uncommon in chronic hepatitis B (CHB) patients on nucleoside analogues (NAs) therapy. The purpose of this study is to optimize HBsAg clearance in CHB Patients with sequential treatment of pegylated interferon alpha and NAs.
This study will evaluate the safety, tolerability, and efficacy of sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) in adults with chronic hepatitis C infection who have failed to eradicate hepatitis C despite previous combination directly acting antiviral therapy.
The overall aim of this study is to evaluate the prevalence of cognitive impairments and brain anomalies in Chronic Hepatitis C infected individuals and to investigate likely changes in cognition and brain structure and function after treatment with Direct-acting Antivirals (DAAs).
This study is being conducted to determine safety and effectiveness of transplanting kidneys from Hepatitis C-positive donors into Hepatitis C-negative patients on the kidney transplant waitlist, who will then be treated with the appropriate direct-acting antiviral (DAA) after the single kidney transplantation.
