Active clinical trials for "Hepatitis D"

REP 2139-Ca is nucleic acid polymer. Nucleic acid polymers have been previously shown to clear serum hepatitis B virus surface antigen (HBsAg) both preclinically (in duck HBV infected ducks) and in human patients and to act synergistically with immunotherapeutic agents such as pegylated interferon-alpha 2a or thymosin alpha-1 to restore host immunological control of HBV infection. HBsAg is an essential component of the hepatitis D virus (HDV), therefore the direct action of REP 2139-Ca in removing serum HBsAg and its synergistic effect with pegylated interferon-alpha 2a is expected to have a significant antiviral effect against HDV infection. This study will examine the safety and efficacy of REP 2139-Ca therapy when used in combination with pegylated interferon alpha-2a in patients with HBV / HDV co-infection. The primary hypothesis to be tested is that this combined dosing regimen is safe and well tolerated in patients with HBV / HDV co-infection which will be assessed by examining the number of patients with adverse events (including reported symptoms and laboratory abnormalities). The secondary hypothesis to be tested is that this combined dosing regimen will have an antiviral effect against HBV / HDV co-infection in these patients which will be assessed by examining the following outcomes: The number of patients with reductions in serum HBsAg. The number of patients with reductions in serum HDAg and HDV RNA The number of patients that experience a sustained antiviral response after treatment is stopped (reductions in serum HBV DNA and HDV RNA). The secondary hypothesis to be tested is that this combination approach can have an effective

A Phase 2b, Open-Label, Randomized Study of the Safety, Tolerability, and Pharmacodynamic Activity of Lonafarnib With or Without Ritonavir in Patients Chronically Infected with Hepatitis Delta Virus

A project to understand the determinants of health behaviour among those with chronic hepatitis D virus (HDV) infection, under the care of the viral hepatitis service at Kings College Hospital (KCH). This is to improve and implement pathways and patient information distribution to improve access to care in an ethnically diverse population living with HDV in the UK. Kings college hospital NHS Foundation Trust is uniquely placed and serves a large diverse population from areas such as pan pacific Asia, Eastern Europe and regions in Africa, where English is not their first language. This diversity is also seen in other London Hospitals but less so in other parts of the UK.

Rationale: Hepatitis delta virus (HDV) is a defective RNA virus that requires presence of hepatitis B virus (HBV) to complete virion assembly and secretion. HBV-HDV coinfection ("hepatitis delta") has been associated with severe liver injury that may result in rapid progression to cirrhosis and hepatic decompensation, as well as a higher risk of liver cancer when compared to patients with HBV mono-infection. Given the low incidence of hepatitis D, experience in caring for individuals with hepatitis delta is limited and management practices vary. Objective: Generate prospective follow-up data to increase our understanding of this rare disease. Study design: Prospective observational cohort study spanning 5 years, during which we will collect standard clinical data as well as blood samples and quality of life questionnaires. Study population: hepatitis delta patients aged ≥18 years Intervention (if applicable): not applicable Main study parameters/endpoints: Incidence of liver related events (liver cancer, (decompensation of) cirrhosis, liver transplantation) during follow-up and changes in markers of viral replication, inflammatory activity and liver stiffness over time. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The risks associated with participation can be considered negligible and the burden can be considered minimal. The only additional action that the participants must perform are the filling out of two annual quality of life questionnaires, which are considered non-invasive, and collection of 10 ml blood during regular blood sample collections

In China, there is no recommendation for Hepatitis D virus (HDV) screening, but the fact is estimated that one-third of the world's population of individuals with chronic Hepatitis B virus (HBV) infection live in China while we do not know the prevalence of co-infection of HBV/HDV in China. So far, no nationwide study has been undertaken to evaluate the epidemiology of hepatitis D, on the other hand, reports of HDV infection rate in different regions of China are not consistent because of the different detection methods and detection objects. Here, we plan to test HDV-Ab/RNA for 5000 HBsAg reactive samples from 10 major tertiary hospital and to know the prevalence and disease burden of HDV in China.

Ezetimibe possesses pharmacophore features to inhibit NTCP, the receptor required for HBV and HDV hepatocyte entry that include two hydrophobes and one hydrogen bond acceptor. Therapy with Ezetimibe may lead to decline in hepatitis D virus levels. The aim of the study is to evaluate the utility of Ezetimibe in patients with chronic HDV infection

This prospective, multicenter, observational study will assess the prevalence of chronic hepatitis D in patients with chronic hepatitis B in Romania and evaluate the efficacy of Pegasys (peginterferon alfa-2a) in patients with chronic hepatitis D. Eligible patients treated with Pegasys according to current medical practice will be followed until 24 weeks after the end of treatment.

Primary objective: To evaluate the safety and tolerability of sequential administration of P1101 and anti-PD1 in patient with chronic hepatitis B or D infection Secondary objectives: To explore HBsAg loss and kinetics during the study period To assess the anti-viral effect during the study period To evaluate the rate of ALT normalization

The treatment of choice for chronic hepatitis D is uncertain. The investigators hypothesize that pegylated interferon (IFN) alfa-2b in combination with ribavirin (RBV) may be effective in the treatment of chronic hepatitis D patients who are also infected by hepatitis B virus (HBV). The purpose of this study is to test this hypothesis. The investigators will use pegylated IFN alfa-2b in combination with RBV for the treatment of patients with dual chronic hepatitis D virus (HDV) and HBV infection. A 24-week course of combination therapy pegylated IFN+RBV will be used.

Ezetimibe possesses pharmacophore features to inhibit NTCP, the receptor required for HBV and HDV hepatocyte entry, that include two hydrophobes and one hydrogen bond acceptor. The aim of the study io evaluate the utility of Ezetimibe in combination with pegylated interferon in patients with chronic HDV infection.
