Filter by:Hepatic steatosis and insulin resistance are associated with severity of fibrosis in non-alcoholic fatty liver disease (NAFLD) and chronic hepatitis C. However, clinical significance of steatosis and insulin resistance on fibrosis in chronic hepatitis B (CHB) is not well established. The aim was to investigate the relationship between insulin resistance, hepatic steatosis, and fibrosis in patients with CHB.
Antiviral resistance remains an important issue for long-term NA therapy. For lamivudine (LAM), the rtM204V/I and rtL180M mutations occur in more than 70% after 5 years of therapy. In Korea, primarily owing to limited subsidization policy in the health insurance system, many patients with LMV-resistance had been treated with either rescue ADV or ETV 1.0 mg monotherapy, ultimately leading to the higher prevalence of MDR strain. For those patients, rescue therapies of combining ADV with either ETV or LAM had been tried, but frequently with suboptimal responses. Rescue TDF monotherapy or TDF-based combination therapy are available in Korea for patients who had "difficult-to-treat" antiviral resistance owing to prior treatment failures. However, which is the better has not been evaluated yet. A long-term efficacy and safety of TDF-based rescue therapies in real practice for those patients should be necessary to revise the Korean guideline for the treatment of chronic hepatitis B in near future.
Define the patients who lost HBsAg, studying the loss predictive factors and if there was suspension of treatment, study the evolution after that
This is an open label study that will be conducted at a single site in China to evaluate the safety,tolerability and PK/PD profile of multiple dose of recombinant human serum albumin/interferon alpha2a fusion protein in chronic hepatitis B patients.The total duration of study participation is up to 22 weeks for each subject,including 4 weeks screening period.
This study is designed to support the optimal use of telbivudine by providing data to refine our understanding of telbivudine efficacy and resistance in real life clinical setting in patients with chronic hepatitis B with defined baseline characteristics and 24-week PCR negativity.
The primary objectives of this study are to evaluate the safety and efficacy of GS-4774 in adults with chronic hepatitis B (CHB) viral infection who have been virally suppressed with an oral antiviral (OAV) medication.
The primary objective of this study is to compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF) in treatment-naive and treatment-experienced adults with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B virus (HBV) infection.
The primary objective of this study is to compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF) in treatment-naive and treatment-experienced adults with hepatitis B e antigen (HBeAg)-negative chronic hepatitis B virus (HBV) infection.
The purpose of this study is to investigate whether HB-Vac Activated-DCs Combined With Peg-IFN or NAs has more efficacy than Peg-IFN or NAs alone in the treatment of chronic hepatitis B patients
Patients with Chronic Hepatitis B on long term oral antiviral therapy have to continue treatment indefinitely unless they achieve HBeAg seroconversion or HBsAg seroclearance, when therapy can be stopped. While HBeAg seroconversion is a more achievable endpoint, only 20-25% of patients develop this after one year of oral antiviral therapy. HBsAg seroclearance is universally infrequent. Strategies to improve these endpoints such as combination oral antiviral therapy have not been generally successful and recently studies have examined the possibility of switching or adding peginterferon therapy. However these have not been tested adequately in the group of patients that have been on long term oral antiviral therapy. Consequently this study was conceived to evaluate whether switching or adding peginterferon compared to continuing oral antiviral therapy are more efficacious strategies. HBeAg positive and HBeAg negative patients (n=310)will be randomised to continue oral antiviral therapy, switch or add pegylated interferon for 48 weeks in a ratio of 1:2:2 respectively. The study endpoints are HBsAg seroclearance, reduction of qHBsAg >1 log, qHBsAg<200 IU/ml, HBeAg loss and seroconversion, and HBV DNA suppression, all at week 72.
