NCT01330316
The objective of this trial is to collect evidence for the safety and efficacy of 24 weeks of treatment with BI 201335 240 mg in combination with 24 or 48 weeks of Pegylated Interferon (PegIFN) and ribavirin (RBV) in treatment experienced patients who have been withdrawn from PegIFN and RBV treatment due to lack of efficacy in the 1220.7, 1220.30 and 1220.47 trials.
NCT00767936
Adult liver cancer is the third leading cause of cancer deaths worldwide. The major risk factor for liver cancer is hepatitis B virus (HBV) infection. The purpose of the study is to sequence the HBV genome in patients with chronic HBV infection, and in patients with liver cancer resulting from chronic HBV infection. The goal is to identify mutations in the HBV genome that predisposes these high risk individuals to the development of liver cancer.
NCT01353989
A lot of elderly people travel to hepatitis A endemic areas. The prevalence of hepatitis A IgG positivity is declining in the Netherlands, also in the elderly. Studies show that people above 40 years of age have a slower immune response to hepatitis A vaccination. However, a lot of travelers seek pre-travel advice only shortly before their journey. More information about the time to adequate antibody response after hepatitis A vaccination is required to provide good protection during travelling. Alternative protection with immunoglobulins are available. Study design: Observational, longitudinal pilot study Study population: 20 adults over 60 years of age with a negative hepatitis A IgG, (with a estimated 50% positivity for hepatitis A IgG in this age Group, 40 patients in this age group) 20 adults 18-40 years of age as controls. Intervention (if applicable): When hepatitis A vaccination is indicated and informed consent is obtained, hepatitis A IgG wil be measured at day 0, 7, 14, 21 en 28. Main study parameters/endpoints: Time to protective hepatitis A IgG. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: hepatitis A vaccination will be given also outside this study. In the study 5 venous punctures of 7 ml of blood.
NCT01577069
The purpose of the study is to 1- detect and quantify HCV-PI resistant mutants with ultra-deep pyrosequencing (UDPS) technology, 2 - detect SNPs in P-glyocoprotein and CYP3A genes, in HCV mono-infected patients under/after Telaprevir treatment.
NCT01592006
Patients are being asked to be part of this study because they are a liver transplant recipient and have the Hepatitis C Virus (HCV). Current routine treatment for HCV for liver transplant patients includes taking two medications called pegylated interferon alfa-2a (Pegasys®) and ribavirin. Patients Pegasys and ribavirin are FDA approved for the treatment of HCV. This study will evaluate the safety and efficacy of adding a third drug called telaprevir for the experimental treatment of HCV in liver transplant patients. The combination of Pegasys, ribavirin and telaprevir is currently FDA approved for the treatment of HCV, but is specifically not FDA approved for HCV patients who have had a liver transplant. This is because more information is needed about possible drug interactions between telaprevir and cyclosporine, or telaprevir and tacrolimus-based immunosuppressive drugs, which are typically part of routine care for transplant patients. Studies have shown that the addition of telaprevir greatly increases the efficacy of Pegasys and ribavirin for the treatment of HCV. However, these studies did not include adequate information on transplant patients due to the potential drug interactions. The investigators hope to gather more information about the safety and efficacy of telaprevir given in combination with Pegasys and ribavirin in the liver transplant patients who have HCV that is not well controlled with Pegasys and ribavirin alone.
NCT01525628
To evaluate the drug-drug interactions between BI 201335 and BI 207127 as well as their combined effect on CYP probe drug substrates and on tenofovir and raltegravir in treatment naive or prior treatment relapse patients with chronic hepatitis C infection.
NCT02791256
This multicenter, open-label, uncontrolled study will evaluate the efficacy and safety of increasing the dose of peginterferon alfa-2a (Pegasys) in participants with Genotype 1/4/5/6 CHC and an early non-response to a standard course of peginterferon alfa-2a plus ribavirin. The study will consist of screening (4 weeks), treatment (32 weeks), and follow-up (24 weeks).
NCT02793791
The aim of this study is to determine that for hepatic dysplastic nodules in patients with chronic hepatitis B, instead of enhanced follow-up, whether early minimally-invasive ablation therapy can reduce the incidence of hepatocellular carcinoma.
NCT02292966
The purpose of this study is to examine whether neurocognitive impairments experienced by patients with chronic hepatitis C virus (HCV) infection can be reversed by treating HCV, with a new combination of direct acting antiviral drugs (daclatasvir (DCV), asunaprevir (ASV) and beclabuvir (BCV)). The study will assess the effect of HCV on the central nervous system (CNS) by assessing neurocognitive function and brain injury prior to treatment, and comparing it to the end of treatment, and 4, 12 and 24 weeks after treatment.
NCT01492426
The purpose of this study is to compare the effectiveness of BMS-790052 (Daclatasvir) and Telaprevir when given in combination with Peginterferon alfa-2a and Ribavirin in genotype 1b patients
NCT02779465
The purpose of this study is to determine whether vitamin D is effective in the prevention of hepatocellular carcinoma in those patients with chronic hepatitis B.
NCT02648022
To determine the effect of an integrated care protocol on antiviral treatment and sustained virologic response (SVR) rates following initiation of direct acting antiviral therapies (DAA) treatments in 2011.
NCT02417597
This phase IV clinical study was designed to evaluate the safety and immunogenicity of the recombinant Hepatitis E vaccine(Hecolin®), manufactured by Xiamen Innovax Biotech CO., LTD., in healthy volunteers aged over 65 years of age at enrollment. The study volunteers will receive the 3 doses of Hecolin® administered intramuscularly according to a 0-1-6 month schedule.
NCT02361541
Hepatitis C (HCV) is an important global public health problem, disproportionately affecting HIV positive populations. Asia and Africa account for most of the co-infection burden, but access to HCV screening and treatment is still very limited. It is expected though, with the recent therapeutic advances and increasing global advocacy efforts, that HCV treatment should become a feasible option in the near future. Sihanouk Hospital Center of HOPE (Phnom Penh, Cambodia) is catering for one of the largest HIV cohorts of the country, followed in an ambulatory settings. In this cohort, the prevalence of HCV co-infection will be determined, as well as HCV genotype diversity and the severity of liver disease. The researcher will also explore the performance of simple blood tests/panels as predictors of significant fibrosis and/or cirrhosis. Patients will attend two study-visits. All adult patients of the HIV patient cohort of SHCH will be proposed HCV testing during their next HIV follow-up consultation, following the latest algorithm of the Centre for Disease Control (CDC) (May 2013). Anamnesis and clinical examination will focus, additionally to routine practice, on presence of general and HCV liver-disease related features. Laboratory analyses will include basic HIV tests (CD4), and tests for liver function such as Hepatitis B surface antigen (HbsAg) . During the following routine HIV follow-up consultation, the results of HCV testing will be explained to the patient. If the patient is HCV negative, his/her study participation ends here. If currently infected with HCV, the clinician will repeat the HCV liver-disease (extra-hepatic \& hepatic) related anamnesis and clinical examination, and prescribe additional blood tests for the non-invasive liver fibrosis/cirrhosis blood panel tests, liver and kidney function. Patients will moreover be asked to undergo a liver ultrasound and liver stiffness measurements.
NCT02148471
The first aim of this study is to assess oxidative stress and nutritional status in patients with elevated liver enzymes who were found to have either simple steatosis (SS) or nonalcoholic steatohepatitis (NASH) or normal histological findings on liver biopsy by measuring liver lipid peroxides and tumor necrosis factor (TNF)-α, liver pathology and immunohistochemistry, liver function tests, liver and red blood cell membrane fatty composition, insulin resistance (IR) parameters, plasma lipid peroxides, plasma antioxidant vitamins and antioxidant power, lipid profile, subject demographics, medical history and medication use. The second aim is to detect differences in hepatic gene expression (messenger RNA, mRNA) and epigenetic regulation (micro RNA, miRNA) between patients with SS or NASH and healthy controls, in addition to determine in patients with non-alcoholic fatty liver disease (NAFLD = SS+NASH combined) whether there is an association between hepatic n-3 PUFA content and gene expression. The third aim is to determine the intestinal microbiome (microbial composition and metagenome) in patients with SS or NASH and healthy controls.
NCT02768545
NPC1L1 is a key transporter in the enterohepatic cycle of cholesterol. Initial in vitro and in vivo data show that blocking this receptor with ezetimibe results in delaying infection in these models. The investigators hypothesize that HCV has an enterohepatic cycle, being secreted in bile and reabsorbed either in the canalicular membrane or in the intestine by association with NPC1L1, following a path similar to the cycle of cholesterol in humans. To prove this hypothesis the investigators propose to assess the effect of ezetimibe treatment in HCV infected individuals undergoing liver transplantation to avoid or delay HCV infection. For this purpose, the investigators propose to administrate ezetimibe 10 mg/d for 12 weeks to 12 patients with chronic hepatitis C infection listed for a liver transplantation.
NCT02764671
