Filter by:The study is an open-label, randomized, comparative, multicenter clinical trial. The purpose of this study is to assess the efficacy of ABX203, a new chronic hepatitis B therapeutic vaccine administered as an adjunct therapy to nucleos(t)ide analogs (NUCs), in maintaining control of Hepatitis B disease after cessation of treatment with NUCs in subjects with HBeAg negative chronic Hepatitis B.
Chronic Hepatitis B infection (CHB) is known as the most frequently identified cause of liver disease that predisposes patients to the development of hepatocellular carcinoma (HCC). Active hepatitis B virus (HBV) replication is the key driver of liver injury and disease progression. Majority of Chinese patients are infected with genotype B and C HBV, which is different from Caucasian counterparts. This prospective multi-center cohort open-label study is designed to investigate the long-term effect of TDF on prevention of HCC and disease progression as well as to evaluate the efficacy and safety of long-term TDF in Chinese CHB subjects with advanced liver diseases. The study will enrol 240 subjects.
The purpose of this study is to evaluate the efficacy of Oxymatrine plus Lamivudine Combination Therapy and whether it could lower the incidence of Lamivudine long-term resistance compared to Lamivudine Monotherapy.
This open--label, multicenter, national observational study will investigate the effectiveness of standard of care treatment with peginterferon alfa-2a in participants with chronic hepatitis B (CHB). Participants who have never received any hepatitis B virus (HBV) treatment and participants previously treated with nucleos(t)ide analogs (NAs) are qualified for enrollment. The observation period is 48 weeks (peginterferon alfa--2a standard of care treatment) and for up to 24 weeks thereafter (72 weeks in total).
This is a phase IV, single-arm, open-label, multi-centre study to assess the efficacy of TDF in Chronic hepatitis B (CHB) subjects following failure of multiple Nucleos(t)ide analogues (NAs). The study will enrol 200 CHB subjects following failure of multiple NAs. Subjects will be assessed for eligibility at a screening visit, with eligible subjects returning for a baseline assessment after approximately 4 weeks (Screening phase). In the treatment phase all enrolled subjects will receive open label TDF at a dose of 300 milligrams (mg) orally once daily. All the eligible study subjects will undergo safety and efficacy assessments every 12 weeks for a total of 14 visits. Tenofovir disoproxil fumarate, the oral pro-drug of tenofovir (TFV), is a nucleotide analogue that inhibits viral polymerases by direct binding and after incorporation into deoxyribonucleic acid (DNA), by termination of the DNA) chain. TDF is a highly potent treatment in treatment-naïve and lamivudine (LAM) resistant CHB patients. The purpose of our study is to evaluate the efficacy of TDF treatment in Chinese CHB patients following failure of multiple NAs. In addition, the study will also explore the relationship of baseline factors and early HBV DNA suppression to long-term virological response. The efficacy of TDF in multi-drug resistant patients will be analysed separately. The data generated by this study could then be used to optimize the clinical application of TDF and provide new evidence for management of the HBV infections following failure of multiple NAs. The result of this study will help Chinese physicians better manage the CHB patients following failure of multiple NAs.
The primary objectives of this study are to evaluate the safety, tolerability, and efficacy of GS-4774 in adults with CHB and who are currently not on treatment. Participants will be randomized to receive TDF alone or GS-4774 plus TDF for 20 weeks. After Week 20, GS-4774 will be discontinued. All participants will continue on TDF and will be followed for an additional 28 weeks. Following completion of the 48 week study period, all participants will be eligible for a treatment extension for 96 weeks.
The study was conducted to evaluate the effect of anti-viral treatment on long-term outcome on patients with chronic hepatitis B.
This non-interventional clinical study will be conducted to prospectively collect serial plasma samples from subjects with chronic HBV infection who are initiating antiviral therapy. These samples will be used to estimate clinical utility endpoints for the Aptima HBV Quant assay, which is used as an aid in the management of HBV-infected patients undergoing HBV antiviral therapy.
The primary objectives of this study are to evaluate the safety, tolerability, and efficacy of vesatolimod in participants with chronic hepatitis B (CHB) infection currently being treated with oral antivirals (OAV). Participants will be randomized in 3 sequential cohorts (Cohorts A, B, and C). Within each cohort, participants will be randomized in a 1:3:3:3 ratio to placebo or one of the doses of vesatolimod (1, 2, or 4 mg).
In this project proposal, the investigators will investigate the genetic alterations of Hepatitis B Virus (HBV) strains circulating in Belgian patients who developed end stage liver disease. Additionally, the investigators will compare and link these data sets with three genetic factors involved in immune system response.
