Active clinical trials for "Hepatitis B"

* AIMS OF THE STUDY To test if steroid-free chemotherapeutic regimens decrease the risk of HBV reactivation and hepatitis development in HBsAg (+) carriers. To compare the efficacy of steroid-free chemotherapeutic regimens with that of steroid-containing regimens in terms of lymphoma control. To study the change of activity of HBV and other hepatotropic viruses during the course of chemotherapy.

The purpose of this clinical research study is to assess the safety effectiveness of entecavir, as compared to lamivudine, in the treatment of adults with chronic hepatitis B infection who are hepatitis B e antigen positive.

The investigator aimed to prospectively study the effect of the hepatic fibrosis on quantifying hepatic steatosis using ultrasound attenuation imaging (ATI value) in patients with chronic hepatitis B.

The changes in liver function, body mass index, controlled attenuation parameters, liver stiffness and HBV-DNA at different time points in each group before and after treatment were counted to explore the clinical efficacy of Ganshuang granules combined with tenofovir in the treatment of CHB complicated with NAFLD.

The primary aim of the study is to accomplish two major tasks: the first is to determine the frequency of intra-familial transmission of HBV; the second is trying to explore the potential risk factors of such a transmission .As a secondary aim, immunologic status of the household contacts vaccinated for hepatitis B will be evaluated to assess the efficacy of hepatitis B vaccination and its role in prevention of intra-familial transmission of HBV

Assessment of the effectiveness of intralesional and intramuscular hepatitis B vaccine in treatment of multiple common warts.

Establishment and validation of the non-invasive model to predict antiviral therapy in the gray zone of chronic hepatitis B

Inflammatory bowel disease (IBD) has witnessed a rising incidence globally and in Hong Kong, an area where chronic hepatitis B (CHB) remains endemic. IBD patients are usually immunocompromised due to the disease itself and secondary to the use of medications including immunosuppressants and biologics, predisposing them to various opportunistic infection including hepatitis. Vaccination against hepatitis B virus (HBV) is recommended to prevent CHB and its related complications including flare up of acute hepatitis, cirrhosis and hepatocellular carcinoma. However, it is reported that efficacy with conventional intramuscular hepatitis B vaccination in IBD patients is suboptimal, especially among those receiving biologic therapies. Various strategies in boosting vaccine immunogenicity including the utilization of higher vaccination dose, shorter dosing interval, or alternate route of vaccine administration have been studied.6 Intradermal route of vaccination has been recently shown to be an effective way in augmenting immune response in specific patient groups who are known poor responders, including elderly and immunocompromised patients. In addition, topical imiquimod, a synthetic agonist of toll-like receptor 7 (TLR7), has been shown to further boost up the immunogenicity response when applied to the site before intradermal vaccination. The proposed study is the first clinical trial comparing the efficacy of intradermal hepatitis B vaccination with adjuvant topical application of imiquimod cream with the conventional intramuscular hepatitis B vaccination in IBD patients.

This study is designed to assess the relative bioavailability of ABI-H2158 tablets (Test Formulation) compared to ABI-H2158 tablets (Reference Formulation). The effect of food on the pharmacokinetics of the Test Formulation will also be evaluated under fed and fasting conditions.

To explore the effective dose and safety of the effect of hydronidone and entecavir on hepatic fibrosis in chronic viral hepatitis B.
