NCT04431245
Chronic hepatitis B (CHB) infection affected 292 million individuals in the world, translating to about 3.9% of global prevalence. Up to 40% of patients with CHB will develop liver-related complications. Many patients require long-term oral antiviral therapy since off-treatment sustained virological control can only be achieved in a minority of patients. It is uncommon for patients taking long-term antivirals to be able to stop the treatment if favorable factors are not present. Those include low viral load, long enough duration of treatment, and absence of cirrhosis. Some studies have found that inducing a mild flare is beneficial for achieving functional cure in chronic hepatitis B infection. There is lack of data in the immunological and virological profile in patients who stop their long-term antiviral therapy, and in those who developed flare after treatment cessation.

NCT07274345
This study aims to determine the prevalence of antiviral drug resistance among Egyptian patients with chronic hepatitis B virus (HBV) infection and to identify the associated demographic, clinical, and virological risk factors. Understanding patterns of resistance will help improve treatment selection and optimize long-term management strategies for HBV patients.
NCT07231276
In this study, comparisons will be made between the treatment group (which will receive pegylated interferon alfa-2b treatment) and the observation group (which will receive no drug treatment or be treated with nucleos(t)ide analogs). The primary objectives are to address the following questions: compare the efficacy evaluation indicators (with clinical cure rate as the primary one) between the pegylated interferon alfa-2b treatment group and the observation group; assess whether pegylated interferon alfa-2b treatment improves the clinical cure rate in patients with chronic hepatitis B virus (HBV) infection aged 3 years and above but under 18 years (adolescents and children); and explore optimized antiviral treatment regimens for adolescents and children with chronic HBV infection. The secondary objectives are to address the following questions: compare the immune response characteristics between adolescents and children with chronic HBV infection who achieved functional cure after pegylated interferon alfa-2b treatment and those who did not; investigate the immune mechanism underlying the achievement of functional cure in adolescents and children with chronic HBV infection treated with pegylated interferon alfa-2b; and identify plasma markers associated with treatment efficacy for predicting therapeutic outcomes.
NCT00988767

NCT06638320
The goal of this observational study is to determine the prevalence of hepatitis D virus (HDV) and the distribution of the HDV genotype in patients with chronic hepatitis B infection. It will also identify factors related to hepatitis D virus infection, such as characteristics of the study sample, vaccination history, drug use affecting hepatitis, family factors, environment, and lifestyle. This study will be conducted at Tam Anh General Hospital, Bach Mai Hospital and Tam Anh TP. Ho Chi Minh General Hospital. Participants will be interviewed directly through a questionnaire to collect some information related to epidemiological risk factors. A blood sample will also be collected.
NCT06263959
A randomized, double-blind, placebo-controlled Phase IIa clinical study to evaluate the safety and efficacy of GST-HG131 tablets in patients with chronic hepatitis B
NCT06295328
Rationale: Currently, there is no curative therapy available for patients that are chronically infected with the hepatitis B virus (HBV). Especially the presence of a viral reservoir of stable episomal, covalently closed circular DNA (cccDNA) in the nucleus of infected hepatocytes poses a great challenge for the development of curative therapies. HBV cccDNA acts as the template for production of viral proteins and HBV genomes. In a preclinical study, terbinafine (an antifungal agent) was identified as a potent and specific suppressor of HBx-mediated cccDNA transcription. HBx is an accessory viral protein of HBV which has been proven to be essential for HBV replication and enhances replication at the transcriptional level in vivo. The suppression of cccDNA transcription results in a strong reduction of the production of viral genomes (RNA and DNA) as well as viral proteins. This will allow recovery of the immune system, increase viral clearance and prevent replenishment of the cccDNA pool in the hepatocyte, all contributing to cure chronic hepatitis B (CHB). Objective: to provide proof of concept for the inhibition of HBx mediated cccDNA transcription by terbinafine, both as monotherapy and add-on therapy next to tenofovir. Secondary outcomes will be the safety and tolerability of terbinafine in this specific group. Study design: This pilot study is a stratified, single center, randomized, double-blinded, placebo-controlled, dose-ascending proof of concept clinical trial. Study population: patients chronically infected with the hepatitis B virus with a normal liver function and no signs of liver damage, who do not use any antiviral medication (group A, n=16) or are treated with tenofovir \> 6 months (group B, n=16). Intervention: Patients will be randomly allocated to daily oral treatment with terbinafine or a matched placebo, either as monotherapy (group A) or as add-on therapy to tenofovir (group B). Main study parameters/endpoints: Primary outcomes: decline in level of serum HBsAg \>0.32log10 IU/mL in both groups A and B and decline in serum HBV DNA \>0.86log10 in group A at the end of study treatment (week 10 vs baseline). Secondary outcomes: 1) Safety and tolerability of terbinafine as mono- or combination therapy; 2) level of serum HBsAg and HBV DNA at 3 months follow-up; 3) decline of HBsAg levels over time (all visits); 4) HBV RNA, large HBsAg (LHBs) HBcrAg levels, and HBeAg status at baseline and end of study 4). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients participating in this study will undergo physical examinations and blood sample collections (13 samples and in total 467.5 mL). They will also be asked to fill in the HBQOL and EQ5D5L quality of life questionnaires and a medicine diary. In total there will be 13 visits in the hospital of which 7 will be for blood collection only. Terbinafine can induce liver damage 1 of 50,000 to 120,000 prescriptions (LiverTox), a weekly safety laboratory control is implemented in the visits to detect possible liver toxicity in an early stage and prevent liver damage.
NCT05410496
tenofovir alafenamide (TAF) has been approved to be highly effective and safe in patients with chronic hepatitis B (CHB), therefore TAF may be a good option in kidney or liver transplant patients with chronic HBV infection. The aim of this prospective cohort study is to assess the safety, efficacy, and drug adherence improvement of TAF switching therapy in kidney or liver transplant patients with HBV infection.
NCT06707922
Studies have shown that chronic hepatitis B patients with low levels of HBsAg after nucleos(t)ide analog therapy have a higher chance of functional cure with sequential or combined pegylated interferon therapy, with about 30-50% of patients achieving HBsAg clearance and discontinuing therapy. There are some clinical practices on the long-term benefits of discontinuing antiviral therapy, but there is a lack of evidence-based clinical studies, especially on the relapse rate, duration of relapse, and factors influencing relapse after achieving functional cure. Furthermore, there is no guideline or expert consensus on the follow-up management strategy for patients who haven't achieved functional cure but whose HBsAg levels have been substantially reduced by treatment and are at low levels. Therefore, this study is planned to enroll participants who have completed the TB1901IFN to evaluate the long-term benefit of Peginterferon in combination with tenofovir disoproxil fumarate（TDF） and relapse in patients who have achieved functional cure, for participant with low-level HBsAg at the end of treatment, peginterferon combined with tenofovir alafenamide fumarate （TAF）therapy will be administered to explore the efficacy and safety of starting treatment after a period of drug discontinuation. Participants will be divided into 3 cohorts based on functional achievement and/or HBsAg levels after completion of TB1901IFN
