Filter by:Hepatitis B virus (HBV) leads to life-threatening disease like liver failure and liver cancer. For most, a cure is unattainable as current HBV antiviral therapy (using nucleoside analogues) are not able to clear the virus from their liver. While HBV treatments are typically administered alone (monotherapy), this study will explore the use of Ribavirin in combination with standard therapy to enhance current treatment regimens. Ribavirin is commonly used to treat Hepatitis C Virus (HCV) but there is evidence that Ribavirin also induces immune effects that are beneficial in HBV treatment. The aim of this study is to determine whether combination of Ribavirin and a nucleoside analog is more effective compared to nucleoside analog treatment alone. Enrolled patients will be followed for treatment response according to standard clinical and virological tests, as well as immune response to HBV. Our ultimate goal is to find a more effective treatment and improve health outcomes for persons living with HBV.
Treatment with Tenofovir Alafenamide(TAF) in Chronic Hepatitis B (CHB) patients classified as beyond treatment indication of current international guidelines (e.g. aged more than 40 years old and 4 ≤ log HBV-DNA IU/mL < 8) is expected to bring improvement in long-term clinical outcomes. This expected result may expand the treatment indications in patients with CHB based on age and HBV-DNA in contrast to current international guidelines of CHB.
This study is a multi-center, prospective, real-world study, males and non-pregnant, non-lactating female HBeAg positive or negative patients (above 18 years of age) who were mono-infected with HBV, either NA treatment-naïve or treatment-experienced, but TAF naïve will be enrolled in this study, and they will be treated with TAF, alone or in combination with other HBV antivirals. During 36 months of treatment, efficacy and safety will be evaluated.
It remains unknown whether antiviral therapy is beneficial for chronic hepatitis B (CHB) with normal or mild ALT.The investigators aim to evaluate the antiviral indications combining liver biopsy and clinical parameters,and further clarify the response indexes of clinical results such as virological, serological, biochemical and histological responses from a retrospective observational cohort study on antiviral therapy in HBeAg positive and negative patients with different ALT levels,especially when ALT lower 2 times upper limit of normal (ULN).
The investigators observed the level of IL-35 secreting B regulatory (IL-35+Bregs) cells in peripheral blood cells in patients with chronic hepatitis B, and analysed the relationship between the IL-35+Bregs level and disease stage, and Th1 and Th2 cells level.
There are chronic hepatitis B patients with poor antiviral efficacy of entecavir in clinical practice. Tenofovir or interferon alfa is the optimal choice right now. The aim of this study is to investigate the therapeutic effect of using tenofovir of interferon alfa in these patients.
This three-part, Phase 1 protocol will be the first clinical study of ABI-H2158. Parts 1 and 2 will be a Phase 1a, dose-ranging assessment of ABI-H2158 in healthy adult volunteers. If the dose-related safety, tolerability, and pharmacokinetics (PK) of ABI-H2158 in healthy volunteers are deemed satisfactory, then the study will advance to Part 3, a Phase 1b, dose-ranging assessment of ABI-H2158 in non-cirrhotic, CHB patients.
This is a retrospective study, all HIV-infected individuals followed up at the three designated HIV clinics in Hong Kong with and without HBV and/or HCV co-infection will be included in the analysis. The incidence and mortality of HCC among HIV-infected individuals with and without HBV/HCV co-infection in an Asian population will be determined.
To investigate the efficacy of using antiviral therapy in third trimester of pregnancy to reduce mother-to-infant HBV transmission, and to access the safety of such treatment for mothers and infants.
The TARGET-HBV study engages an observational research design to conduct a comprehensive review of outcomes for patients with CHB infection. The initial phase of the study that enrolled patients treated with tenofovir alafenamide (TAF) was successfully completed. The current protocol (Amendment 1) describes the second phase of the study that will engage research activities for patients being managed for CHB in usual clinical practice in the US and Canada. The study addresses important clinical questions regarding the management of CHB by collecting and analyzing data from patients at academic and community medical centers. TARGET-HBV creates a robust database of real-world data regarding the natural history, management, and health outcomes related to antiviral treatments used in clinical practice.
