NCT02782247
Chronic viral hepatitis often leads to liver scarring - cirrhosis. If the virus is eradicated from the liver, the liver scarring and liver function often recovers. In some patients the damage is too severe and recovery does not take place. It is not yet known which patients have liver disease that is too advanced to benefit from therapy nor is it known how fast the recovery occurs. Non-intrusive dynamic liver testing (DLT) may allow us to predict the functionality of the liver post treatment and may guide us in treatment choices - for example patients who are predicted not to recover may be prioritised for transplantation. Indocyanine green (ICG) is a dye solely excreted by the liver into bile and used to measure its dynamic function. Transient elastography is similar to ultrasound and measures the degree of fibrosis within the liver. The investigators hypothesise that the use of non-intrusive dynamic liver testing pre-treatment, will allow us to delineate patients before therapy who will have functional liver recovery following viral eradication. The investigators hypothesise that monitoring changes in liver fibrosis and liver function in patients with historical viral clearance will allow an assessment of the likely speed of recovery of liver fibrosis and function - for example if all patients 5 years after treatment for viral hepatitis induced cirrhosis have 'normal' fibrosis and liver function scores the investigators will be able to conclude that recovery is complete within 5 years. The investigators will perform a study pre and post-treatment assessing liver function using non-intrusive dynamic liver testing in addition to currently-used 'liver function' scoring systems, in a multivariate analysis, to determine whether or not the investigators can identify patients who are will have functional liver recovery post therapy.
NCT01439776
Standard therapy for chronic hepatitis C virus (HCV) is (Peg/RBV) combination therapy obtaining sustained virologic response (SVR) in 77% of naïve patients with genotype 1-3 Studies rarely address the issues of improving host factors. The current study examines whether adding vitamin D with Peg/RBV, a potent immunomodulator, could improve viral response(SVR)compared to Peg/RBV.
NCT03540212
This is an interventional Phase II/III, single center, single arm clinical trial to assess the pharmacokinetics, efficacy, safety and tolerance of daclatasvir plus sofosbuvir in treatment-naïve, non-cirrhotic adolescents with chronic HCV GT-4 infection. A single-arm evaluation of daclatasvir/sofosbuvir will focus on the pharmacokinetics, efficacy and safety All enrolled patients will receive daclatasvir 60 mg orally once daily plus sofosbuvir at a dose of 400 mg orally once daily for 12 weeks.
NCT04353986
This is a prospective, controlled, open-label, pharmacokinetic study. This study aims at studying the PK of sofosbuvir, ledipasvir and sofosbuvir metabolite (GS-331007) in HCV infected children with hematological Disorders. to develop predictive pharmacokinetic model for the 3 moieties in the studied population. In this study, patients in both treatment groups will receive 12 weeks of treatment with a fixed-dose combination tablet containing 400 mg of sofosbuvir and 90 mg of ledipasvir(SOF/LED) orally, once daily with food.
NCT05752890
The investigators will first use our previously collected serum samples and surgical/biopsied tissues from HBV-related HCC patients undergoing radiotherapy. The consistency of junctional clones by Capture NGS needs to be tested between both pre- and post-RT serums, and serial changes in copy numbers of vh-DNA by ddPCR are quantified in the representative cases. The same junction clones from pre-post-RT serums and surgical tissues will be confirmed and the copy number changes of vh-DNA be correlated with RT response and disease-control status. The investigators plan to identify HBV integrations by Capture NGS and quantify the specific vh-DNA by ddPCR as personalized biomarkers from the same-patient serum samples. The investigators will further correlate clinical response and recurrence/metastasis with serial changes of vh-DNA copy numbers. The investigators have been prospectively collecting plasma samples from HBV-related HCC patients before/after RT, at 1, 4, 7 months, and at recurrence/metastasis. The investigators plan to confirm the viable role of pre-/post-RT changes of plasma vh-DNA copies of the same junction clone in post-RT response and prognosis. Moreover, The investigators will explore the recurrent/metastatic tumors arising from the original or a de novo one by identifying their clonality with HBV integration patterns. The true value of this novel HBV chimera vh-DNA will be revealed. The results will also support the consolidative use of personalized vh-DNA for earlier evaluating treatment response after RT, for post-RT disease monitoring, and for differentiating clonality at recurrence to design future clinical trial on combinational treatment.
NCT05753280
In recent years, vitamin D (VD) has received much attention in the fields of host immune regulation, inflammation, fibrosis, cell proliferation and differentiation and tumor. VD works by binding to the vitamin D receptor (VDR). VDR is mainly distributed in giant cells, dendritic cells, T cells and lymphocytes. Four SNPs of VDRS have been most studied: TaqI (rs731236), FokI (rs10735810), ApaI (rs7975232), and BsmI (rs1544410). At present, more and more patients have been treated with oral nucleotide/nucleoside analogues (NAs) with direct antiviral drugs in China, and a large part of them show low expression of HBsAg. Clinical cure can be pursued for these patients, that is, HBsAg turns negative. A number of studies have been carried out at home and abroad. In this study, We will recruit CHB patients with low HBsAg levels. They all will receive pegylated interferon treatment and were randomly assigned to a vitamin D treatment or a control group. A final assessment will be made to determine whether vitamin D levels would affect the clearance rate of HBsAg.
NCT03496233
Antiviral treatment of G1b Treatment-Naïve HCV-Infected Patients, with non- severe fibrosis, with or without insulin resistance (IR) and/or diabetes mellitus (DM) with EBR/GZR Fixed-Dose Combination for 8 Weeks.
NCT03214679
The proposed study will examine the feasibility, acceptability, safety, effectiveness, and cost of an Accessible Care intervention for engaging people who inject illicit drugs (PWID) in hepatitis C care. Accessible Care for PWID is low-threshold care provided in programs designed specifically for PWID where they can comfortably access care without fear of shame or stigma. Accessible Care will be provided by co-locating a hepatitis treatment provider, together with a Hepatitis C Care Coordinator (HCCC), on-site at a collaborating needle exchange program. The proposed study will compare the effectiveness of Accessible Care with Usual Care (referrals to existing services) in facilitating linkage, engagement, and retention of PWID in care for hepatitis C, addiction, and HIV prevention. The primary outcome is sustained virologic response, which constitutes virologic cure. Substance use and HIV and HCV risk behaviors are secondary outcomes.
NCT03524365
Bariatric-metabolic surgery is effective in treating the cluster of conditions forming the metabolic syndrome, strictly associated with NAFLD and NASH. Recently, we and other authors have shown also in the long term (up 5 years) with randomized-controlled trials (RCTs) that bariatric-metabolic surgery allows remission of type 2 diabetes and obesity reduction, which are the two major pathogenetic factors of NASH development, with maintenance of weight loss. Few small and mainly retrospective studies have shown that bariatric surgery is effective in improving NASH histologic picture in obese subjects. The aim of our proposal is to conduct a 3 arm single centre, superiority, RCT comparing Roux-en-Y Gastric Bypass (RYGB) with Sleeve Gastrectomy (SG) and with Intensive Lifestyle Modifications (ILM) for the treatment of Non-Alcoholic Steato-Hepatitis.
NCT04829123
A Phase 1, double blind, placebo controlled, single and multiple ascending dose, safety, tolerability, pharmacokinetic, and pharmacodynamic study of HEC88473 in healthy subjects
NCT03804814
This study addresses a difficult barrier to hepatitis C elimination, specifically development and maintenance of a productive relationship between the health care provider and patient to ensure both treatment success and engagement in harm reduction services. Improvements in these domains may be observed through the use of a technique called "Motivational Interviewing" (MI). The aim of this study is to determine whether a customized motivational interviewing curriculum by general primary care and addictions medicine primary care providers changes rates of curative hepatitis C therapy completion.
NCT03640728
HBV-related acute-on-chronic liver failure (ACLF) is a clinical syndrome defined as acute hepatic insult with diagnosed or undiagnosed chronic liver disease. Current clinical guidelines advocate oral antiviral treatment in HBV-related ACLF. However, no conclusion on which nucleoside analogue is the most satisfactory drug for the treatment of HBV-related liver failure has not been reached yet. In this cohort study, the investigators will compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF), Tenofovir Disoproxil Fumarate (TDF) and entecavir (ETV) in HBV-related ACLF in China. In addition, the drug metabolism characteristics of TAF will be explored in such severe liver injury population of HBV-ACLF.
NCT05616598
Hepatitis C virus is commona viral infection. Direct-acting antiviral (DAA) oral drugs has been used in treatment of HCVs. the effect of these drugs on male infertility is still under investigation.
NCT05423834
Tenofovir alafenamide (TAF), a novel prodrug of tenofovir (TFV), has been approved for the treatment of chronic hepatitis B virus (HBV) infection. TAF has been shown to be a potent inhibitor of HBV replication at a low dose, with high intracellular concentration and more than 90% lower systemic TFV concentration than tenofovir disoproxil fumarate (TDF). TAF has been approved in the clinical practice guidelines in the west. Since its availability in Asia in 2017, there have been evolving data concerning its positive impact on renal safety as shown in registration trials. The primary objective of this study is to compare the risk of chronic kidney disease (CKD) progression in chronic hepatitis B patients on TAF versus ETV in a territory-wide cohort in Hong Kong.
NCT05376124
Refractory hepatitis B is to point to although standard application nucleoside (acid) analogue treatment undertakes primary treatment and two strengthen treatment, but existence is persistent viremia. Currently, there is no consensus on salvage therapy for patients who remain virus-positive after a second round of antiviral therapy. This is the first multicenter, prospective, parallel controlled, open-label cohort study to compare the efficacy and safety of TDF/TAF combined with ETV1.0mg regimen versus continuation of the original regimen in the treatment of refractory hepatitis B.
NCT05708560
This multicenter retrospective study aims to study the association between the presence of MAFLD and change in liver stiffness over time in untreated and treated patients with chronic hepatitis B
NCT01953458
* The cohort will integrate clinical, genetic, pharmacogenomics, environmental, biomarkers and behavioral data in a large number of patients and will be a leading equipment for crossdisciplinary and translational research on hepatitis. * The cohort will be the main support for estimating the relative effects of treatments and for further cost-effectiveness studies on the management and treatment options in chronic HCV (Hepatitis C Virus)and HBV (Hepatitis B virus)infections.
NCT03855176
Though HAV is mainly transmitted through the fecal-oral route, infection by sexual intercourse and blood transfusion is also possible. Injection drug users (IDUs) and men who have sex with men (MSM) have a higher risk of acquiring HAV due to their behaviors. Reemerging threat of hepatitis A among MSM in Taiwan has been reported recently. Based on the guidelines for the diagnosis and treatment of HIV/AIDS and the Advisory Committee on Immunization Practices (ACIP), Taiwan, vaccination of individuals against HAV with any of the following indications is recommended: HIV patients, adults with chronic hepatic disease, hemophilia, liver transplantation, occupational exposure, MSM, persons who use injection or noninjection illicit drugs, or persons traveling to or working in countries that have endemicity of HAV. In HIV-infected patients, the immunogenicity to HAV vaccination is sub-optimal in HIV-infected patients and the seroconversion rate is estimated 68-90% after administration of 2 or 3 doses of HAV vaccine. Furthermore, the antibody titers of HIV-infected patients following HAV vaccination are significantly lower compared to those of HIV-uninfected persons. The sub-optimal response among HIV-infected subjects remains an unresolved problem. In this study, the investigators aim to determine the to conduct a randomized clinical trial to compare the immunogenicity of 2 different doses of HAV vaccination (1 dose versus 2 doses) in HIV-infected patients who failed to achieve serologic response in the primary vaccination. This proposal will provide the solid evidence to elucidate the role of booster HAV vaccination in HIV-infected patients without response to primary HAV vaccination.
