Active clinical trials for "Hepatitis A"

The objectives of this study are: To perform a systematic screening and evaluation of the prevalence of infection by hepatitis C virus (HCV), hepatitis B virus (HBV) and human immunodeficiency virus (HIV) in the prison population. To perform an adequate characterization of patients and the characteristics of HCV infection in this population. To evaluate the effectiveness and security in the prison population of an interferon-free antiviral regimen. To evaluate the impact of a strategy of systematic HCV treatment on the rates of persistent infection, reinfection and super-infection in a prison population, in the short, medium and long term.

This study is to evaluate the safety, pharmacokinetics characteristics, and antiviral activities of multiple doses of VIR-2218 in adults with chronic HBV infection in mainland China.

Hepatitis B virus (HBV) infection is a worldwide health problem. It has been proved that the persistence of HBV is associated with the failure to stimulate an efficient HBV-specific immune response. T101, the Chinese counterpart of TG1050, is a replication-defective adenovirus serotype 5 (Ad5) expressing multiple HBV-specific antigens (core, polymerase and envelope) and is used as therapeutic vaccine for chronic hepatitis B patients. The application of T101 aims at inducing a broad HBV-specific cellular immune response and ultimately eliminating HBV infection.

Development of preclinical translational models for chronic liver tumors and diseases study, such as spheroids cultured in autologous medium and murine xenograft models to test the efficacy of new therapeutic strategies.

This is a Phase4, multicenter, open-label, randomized study to demonstrate that the Tenolid Tab switching group is non-inferior to the virologic suppression effect compared to the Viread Tab continuous administration group and evaluate the safety of Tenolid Tab. This clinical trial was conducted on patients who were taking Viread Tab as monotherapy for more than 48 weeks for chronic hepatitis B. At the time of screening(Visit 1), information on factors related to medical history and prognosis including Viread Tab administration were collected retrospectively from the subjects who voluntarily signed the informed consent form (ICF). Only subjects who are determined to be suitable for the study eligibility(inclusion/exclusion) criteria as a result of the screening evaluations are randomized in a 1:1 ratio to one of the two groups at the baseline. Subjects will receive investigational product start on the next day of randomization for 48 weeks. Subjects will visit to the study site on 12, 24, 36, 24 weeks after starting dosing investigational product and evaluated for effectiveness of virologic suppression and safety.

Osteoporosis is a condition that describes compromised skeletal microarchitecture in general, with clinical signs of decreased bone mineral density. Patients with hepatitis c virus infection are at increased risk for developing osteoporosis. Identifying whether patients with hepatitis c virus infection have information and awareness about this disease is crucial. This study is aimed to investigate awareness and knowledge of osteoporosis in patients with hepatitis c virus infection.

This is a multicenter, randomized, controlled Phase IIa study of HH-003 injection, HH-003 injection is a monoclonal antibody targeting Hepatitis B virus. This study aims to evaluate the antiviral activity and safety in subjects with with HBeAg-negative Chronic Hepatitis B treated with nucleos(t)ide reverse transcriptase inhibitors.

Alcoholic hepatitis is related to very high mortality rate. About 40% of the patients died within first 6 months after the detection of the clinical syndrome. Therefore, it is very essential for proper diagnosis and early treatment . In response to acute or chronic liver damage, bone marrow derived stem cells can spontaneously populate liver and differentiate into hepatic cells. Animal and human studies suggested that injured hepatocyte may be replaced by pluripotent bone marrow cells. However, this hepatocyte repopulation is highly dependent on varieties of liver injury and therapeutic conditions. The studies have suggested Granulocyte-colony stimulating factors (G-CSF) can regenerate hepatocyte by fusing with hematopoietic cells, thereby enhancing the liver histology and survival rate. G-CSF is a cytokine capable to regulate a number of functions in neutrophils. In three recent studies mobilization of bone marrow stem cells induced by G-CSF was observed in patients with alcoholic hepatitis. In two of these studies there was a survival benefit with the use of G-CSF. Alcoholism leads to decrease in endogenous antioxidant potential. Alcoholic liver disease (ALD) patients show low endogenous antioxidants. Chronic ethanol consumption cause selective deficiency in the availability of reduced glutathione (GSH) in mitochondria has been reported. This is due to impaired functioning of GSH transporter from cytosol to mitochondrial matrix. The effect on glutathione replenishing potential by N-acetyl cysteine (NAC) can be used to reduce oxidative stress, which also has excellent safety profile. Therefore, NAC can be used for severe alcoholic hepatitis treatment due to its therapeutic potential factor. NAC also inhibit apoptosis and pro-inflammatory cytokine production. In a study high doses of intravenous N-acetyl cysteine therapy for 14 days conferred neither survival benefits nor early biological improvement in severe acute alcoholic hepatitis patients with adequate nutritional support.However, these results must be viewed with caution, since the study suffered from a lack of power. In a recent study, NAC and corticosteroids combination therapy benefits among patients with severe acute alcoholic hepatitis in 1 month survival, although the final outcome at 6 month survival was not improved. There are no studies on the use of combination therapy of 4 weeks of NAC plus G-CSF in patient with severe alcoholic hepatitis. Therefore the investigators plan to study the safety and efficacy of combination therapy of G-CSF and 4 weeks of NAC in the patients with alcoholic hepatitis.

Chronic hepatitis C virus (HCV) infection represents a crucial health problem in children that greatly influence their quality of life. Many efforts have been directed toward the investment of effective drugs with high safety profiles and with oral administration for better compliance. The development of a new direct-acting antiviral (DAA) made it possible to achieve these goals.

The aim of this study is to assess the HCV screening rate in Arizona by identification of potential HCV patients/subjects through different methods of communication - text message, email, social media, radio, newspaper ads, and flyers.
