Filter by:The purpose of the study is to determine if combination therapy with daclatasvir (DCV) and sofosbuvir (SOF) for 8 weeks is safe and effective in patients who have never been treated previously without liver cirrhosis who are chronically infected with hepatitis C virus (HCV)/HIV-1 Coinfection genotype (GT) 1, 2, 3, 4 patients.
This is a prospective study to determine the incidence, morbidity, mortality and predisposing factors for the reactivation of hepatitis B virus replication during direct anti-HCV treatment of HCV/HBV co-infection patients.
Patients with hepatitis C show impaired neutrophil function. It is not known whether this is a direct of an indirect phenomenon. Using bone marrow biopsies from patients with hepatitis C it is possible to see whether neutrophil granulocyte progenitors are already infected with hepatitis C.
The aim of this study is to characterize neutrophil function in patients undergoing chronic hepatitis C triple therapy with protease inhibitors in comparison to dual therapy with peginterferon and ribavirin and with interferon free treatment regimen to thereby elucidate the possible mechanisms of protease-inhibitor associated infections.
The primary objective of this pilot trial is to evaluate the feasibility of 12 weeks vs. 24 weeks of field-based directly observed therapy (DOT) for HCV therapy in a resource-limited setting. The investigators will compare treatment completion rates among 50 persons chronically infected with HCV who will be randomized to receive either 1) 12 weeks of sofosbuvir (SOF) + ribavirin (RBV) + pegylated interferon alfa-2a (PEG); or 2) 24 weeks of SOF + RBV. Treatment will be delivered daily by field workers at a location of a participants choosing. Secondary objectives are 1) To compare the efficacy of SOF+RBV with or without PEG as measured by the proportion of subjects with sustained viral response at 12 weeks after discontinuation of therapy (SVR12); 2) To evaluate the safety and tolerability of SOF+RBV with or without PEG; 3) To assess the impact of SVR12 on insulin resistance.
Using European data from patients included in the Named Patient Program (NPP) and from the early post-marketing authorization period, the present study aims to describe patient characteristics and to describe the effectiveness of Daclatasvir (DCV)-based regimens in Europe. This will be a retrospective cohort study of patients who received treatment with a DCV-based regimen in the following context: - Patients enrolled within the European NPP in one of the following countries Austria, Denmark, Italy, Sweden, Spain, Switzerland, United Kingdom; or - In those countries where DCV is commercially available (ie, Sweden, Germany, United Kingdom), patients who received DCV during the early post-marketing authorization period The results of this study will contribute to a better understanding of effectiveness of DCV-based regimens in a population that differs from population in the clinical trials, and therefore will provide additional valuable information to inform clinical practice. This study intends to estimate primarily the effectiveness of DCV-based regimens as measured by the sustained virologic response at post treatment follow-up visit week 12 (SVR12). As well as estimate the effectiveness of DCV-based regimens as measured by SVR12 after the end of Hepatitis C virus (HCV). This study intends also to describe as secondary objectives the characteristics (ie, demographic and clinical characteristics and treatment patterns of patients starting a new DCV-based regimens) of patients receiving DCV as well as the effectiveness of DCV-based regimens as measured by: - On-treatment virological response at post treatment follow-up visit Week 4; and - Virological response at the end of treatment (EOT); and - The sustained viral response at post treatment follow-up visit Week 4 (SVR4) and post treatment follow-up visit Week 24 (SVR24); and - The occurrence of virological failure (on-treatment and relapse). An exploratory objective will be to assess the concordance between SVR4 and SVR12 among the overall population treated with DCV.
The purpose of the study is to investigate how the liver is affected with regard to inflammation and fibrosis during Sofosbuvir based treatment regimes of chronic hepatitis C. In order to examine how the liver heals, we want to use blood samples to check for the occurrence of special liver inflammation cells (CD163 and CD206). To assess to which extent fibrosis disappear during treatment, we want to examine the liver with FibroScan (a type of ultrasound examination) and also preferably with extraction of a small tissue sample. We want to examine how the liver function as inflammation and scar tissue decrease, especially concerning the liver's ability to produce proteins. Furthermore, we want to examine with a gastroscopy, if the circulation of blood in the liver is improved after successful treatment with the expected result that potential varicose veins in the esophagus vanish.
Investigation of the effects of the new Abbvie direct acting anti-viral (DAA) treatment of chronic viral hepatitis C infection on the macrophage specific activation marker soluble CD163, portal hypertension determined by the hepatic venous pressure gradient (HVPG), and metabolic liver function determined by the galactose elimination capacity (GEC) test and the functional hepatic nitrogen clearance (FHNC).
This is a Phase 3, open-label, multicenter study evaluating the efficacy and safety of ABT-450/r/ ABT-267 and ABT-333 coadministered with RBV for 12 weeks in HCV genotype 1b, treatment naïve and Interferon (IFN) (alpha, beta or pegIFN) plus RBV treatment-experienced Asian adults with compensated cirrhosis.
This is a study to evaluate ABT 450/r/ABT-267 and ABT-333 in treatment-naïve and treatment-experienced Asian adults with subgenotype 1b chronic HCV without cirrhosis.
