Filter by:Evaluation of the rate of sustained virological response among HBeAg-negativechronic hepatitis B patients who discontinue long-term NA therapy. During this study participants will cease their prescribed medications, this will occur with immediate effect once enrolled into the study. The duration of cessation will be indefinite, unless clinically indicated for NA therapy re-start. Participants will be monitored as per protocol following cessation, monitoring will be by clinic visit and through blood test to monitor virological response. Clinical visits will be at the intervals of week 2, week, 4, week 8, week 12, week 18, following this they will be every 3 months out to 2 years when the participant will have completed the trial. Once the participant has completed the trial they will not commence again, the aim is for an indefinite cessation of NA therapy.
The purpose of this study is to investigate antiviral efficacy of the combination treatment with Poly IC and Entecavir and compare with the efficacy of Entecavir mono-therapy for chronic hepatitis B.
Open-labeled, Prospective, Randomized, Multi-center, Interventional, Phase IV study.
To determine the optimal time for the Tenofovir treatment of anti-Hepatitis B Virus (HBV) during the pregnancy among women with chronic HBV infection and high HBV DNA load. This is a randomized, open-label, three-arms, parallel-controlled clinical trial. Pregnant women with high HBV load and normal liver function will be treated with tenofovir during the middle or late stage of pregnancy, started from 24th gestational week, 28th gestational week and 32th gestational week through 1 month postpartum, respectively. The HBV DNA load at 40th gestational week of mothers, the intrauterine HBV infection rate of infants will be compared across the three groups.
The purpose of this study is to compare efficacy and safety of continuing Lamivudine plus Adefovir or Adefovir versus switching to Entecavir plus Adefovir in patients with LAM-resistant chronic hepatitis B who have suboptimal response to Lamivudine plus Adefovir or Adefovir
Chronic hepatitis B (CHB) is a serious liver disease worldwide, and the leading cause of cirrhosis and hepatocellular carcinoma (HCC). HBeAg seroconversion is considered to be the satisfied endpoint of antiviral therapy in HBeAg-positive chronic hepatitis B patients. However, HBV reaction, even reverse back to HBeAg positive and clinical relapse could occur in some patients who achieved HBeAg seronconversion by interferon treatment. In this study, the long-term efficacy of interferon therapy in HBeAg positive patients achieved HBeAg seronconversion after interferon treatment and the factors associated with viral and clinical relapse will be observed.
The most important method to slow down and stop the liver disease progression in patients with chronic hepatitis B is antiviral therapy, by which to achieve maintaining viral response during treatment or obtain sustained viral response after treatment. The aim of the therapy with interferon is make patients obtain immune control to HBV defined as sustained viral response after treatment, however, most patients can't get this target after 48 weeks of interferon treatment, and some patients need extended treatment in clinical practice to enhance the rate of sustained viral response or HBsAg loss occurred during treatment. In this cohort study, the efficacy of extended therapy of interferon in HBeAg negative chronic hepatitis B patients will be evaluated.
The aim of interferon therapy in HBeAg positive chronic hepatitis B was to make patients obtain immune control to hepatitis B virus defined as occurred HBeAg seroconversion and HBsAg loss with sustained viral response after treatment. However this target could not be get if patients keep HBV DNA positive during interferon treatment and offend relapse after withdraw of treatment. In this trail, Nucleoside(acid) analogues(NA) will add on patients with HBV DNA load ≥1000copies/ml after 6 months of interferon treatment, and the efficacies of the combine therapy were evaluated by the rates of HBeAg seroconversion and HBsAg loss after 48 weeks of combined therapy, compared with control group.
The aim of interferon therapy in HBeAg negative chronic hepatitis B was to make patients obtain immune control to hepatitis B virus defined as sustained viral response after treatment. However this target could not be get if patients keep HBV DNA positive during interferon treatment and offend relapse after treatment withdraw. In this trail, entecavir will add on patients with HBV DNA load ≥1000copies/ml after 3 months of peginterferon alpha 2a treatment, and the efficacies of the combine treatment will be evaluated by the rate of sustained viral response after 48 weeks of treatment and 24 week follow up.
Antiviral therapy is the most important method to slow and stop the progress of the disease in patients with chronic hepatitis B (CHB). Nucleoside (acid) analogues (NA) can Effectively suppress HBV replication, but it should be continue used and relapse would happen in most patients after withdrawal of therapy. However, long-term use of NA could induce viral resistance mutation lead to loss of efficacy. Interferon treatment can enhance specific and non-specific immune function in chronic hepatitis B patients, make patients get immune control to HBV infection and obtain sustained response after treatment. Thus the CHB patients on the treatment of NA should be stop NA treatment after interferon treatment. In this study, the effects of interferon treatment in CHB patients who were on the NA treatment and obtained HBsAg level≤250 IU/ml.
