Filter by:Immunoprophylaxis failure of hepatitis B (HBV) remains a concern and has been reported in approximately 10-30% of infants born to highly viremic mothers with HBeAg-positive. Maternal HBV DNA >6log10 copies/mL (or 200,000 IU/mL) is the major independent risk for mother-to-child transmission (MTCT). Two recent random controlled trial (RCT) studies have shown that the use of Tenofovir Disoproxil Fumarate (TDF) in highly viremic HBsAg positive mothers may safely reduce the rate of MTCT when compared between groups of TDF treated and untreated patients. Tenofovir Alafenamide (TAF) is the successor to TDF, and both drugs have a similar mechanism of action to reduce HBV DNA levels and normalize serum alanine aminotransferase (ALT) in chronic hepatitis B patients (CHB) with few adverse effects. TAF however, has a better safety profile with less adverse effects to bone mineral density and renal function. The present prospective, double-arm study is to evaluate the non-inferiority in the efficacy and safety of TAF therapy versus TDF therapy in highly viremic mothers and their infants for the prevention of MTCT in the real world setting.
This study was a comparative, randomized, double-blind clinical study of the efficacy and safety of Sci-B-Vac® (10 μg dose) and the Engerix-B® (20 μg dose) vaccines in two parallel groups of hepatitis B-naive healthy adult subjects in Russia.
The aim of CELINE is to retrieve and re-evaluate lost to follow-up chronic hepatitis C patients in the Netherlands.
The purpose of this study is to determine the most effective way to give patients information regarding hepatitis C virus infection. The investigators plan to compare the information retained by some patients who are given a brochure alone versus patients who watch an interactive video about hepatitis C.
The purpose of this study is to evaluate whether Orencia® (Abatacept) improves outcomes in liver transplant patients with recurrent or de novo AIH (autoimmune hepatitis) that has not responded to previous therapy. AIH that does not respond to steroids or conventional immunotherapy often affects young patients and leads to irreversible liver damage. There is currently no effective therapy for this condition.
This study is a single-center, randomized, prospective, open-label Phase 2 Clinical trial to evaluate efficacy and safety of ETV and TQ-A3334 combinated with/without inhibitor of TQ-B2450 versus ETV alone in chronic hepatitis B patients. Patients were randomized to one of 3 different antiviral treatment.
A research study to observe the safety, efficacy and tolerability of switching from Tenofovir Disoproxil Fumarate to Besifovir dipivoxil maleate in patients with chronic hepatitis B
This is a one-time cross-sectional survey study of approximately 200 self-identified black or African-American patients who have had chronic hepatitis C viral infection (HCV) that will evaluate patients' willingness to participate (WTP) in health/medical research related to HCV and attitudinal factors that might be associated with WTP, such as benefits and barriers to research participation, mistrust of physicians/researchers, health literacy, and knowledge of health/research studies.
Both tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF) are potent antiviral agents for hepatitis B virus (HBV) and recommended by the American Association for the Study of Liver Disease (AASLD) as well as the European Association for the Study of Liver (EASL) guidelines for the treatment of nucleos(t)ide therapy induced HBV resistance. However, it is not clear if chronic hepatitis B (CHB) patients with nucleos(t)ide treatment experience without genotypic mutations would be benefit from TAF therapy. Previous studies have observed that suboptimal response (SOR) following antiviral therapy with nucleos(t)ide treatment is associated with an increased risk of subsequent treatment failure and viral resistance. It remains unclear whether switching to TAF is a reasonable approach in patients with SOR to second-line antivirals Lamivudine (LAM)/ Telbivudine (LdT)/ Adefovir Dipivoxil (ADV) and its combinations with other second-line antivirals for 24 weeks, or SOR to the first-line antiviral Entecavir (ETV) or any antiviral combinations containing ETV for 48 weeks. This study is aimed to determine how the aforementioned patients with SOR to nucleos(t)ide treatment respond to TAF monotherapy. The investigator's study will provide evidence base for therapy selection in SOR patients, especially in China where the majority of patients with CHB are treated with nucleos(t)ide therapy.
The goal of this study is to assess the tolerability, pharmacokinetics and antiviral activity of HEC74647 in HCV treatment naïve subjects with genotypes 1-6.
