Filter by:Tenofovir (TDF) has been demonstrated to have potency antiviral against the hepatitis B virus (HBV) in various multiple-centre trials, with no cases of resistance encountered. However, its efficacy and resistance profile in the Asian population, which constitute the majority of chronic hepatitis B (CHB) patients, is unknown. Compared to other nucleoside analogues, TDF has been associated with relatively high rates of hepatitis B surface antigen (HBsAg) seroclearance. It would be interested to see if this could be reproduced. The investigators plan to report the serologic and virologic results of our 140 nucleoside analogue-experienced patients who were commenced on TDF.
This study will compare monotherapy with tenofovir to sequential therapy with pegylated interferon alpha-2b (pegIFN-2b) followed by tenofovir, and to combination therapy with pegIFN-2b + tenofovir, in participants with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B and elevated alanine aminotransferase (ALT). All enrolled participants will be be administered tenofovir alone for 8 weeks and then will be randomly assigned to 1 of the 3 treatment arms.
To compare the effectiveness, in a real world practice setting in tier 2 cities of China, of Entecavir (ETV) monotherapy and Lamivudine (LAM) based therapies (including LAM monotherapy, de novo LAM + Adefovir [ADV] combination, and early add-on of ADV) among chronic hepatitis B (CHB) patients who are naive to NUC at enrollment to this study
Though newly reported HBV infection and HBsAg prevalence in China have greatly decreased, patients who had been chronically infected with HBV, especially those with liver cirrhosis cause great burden on public health care. In view of economic development level, drug availability and lack of independent health economics evidence, the investigators are still unable to give specific guidelines for HBV related compensated liver cirrhosis in China. Therefore, the investigators aim to investigate clinical effects and cost-effectiveness of two early anti-viral therapy strategies on HBV related compensated liver cirrhosis through this prospective, open-label, multicenter and nonrandomized study.
Nucleotide anti-viral analogues, including adefovir and TDF, have demonstrated kidney toxicity in HIV/HBV co-infected patients and HBV mono-infected European patients. Investigators suspected similar kidney proximal tubular injury can also occur in HBV mono infected Asian patients receiving TDF treatment.
Entecavir, a potent antiviral agent, has been widely used for treatment-naïve chronic hepatitis B patients. However, about 20% of patients showed partial virologic response after 2 year of entecavir therapy (33% in HBeAg positive, 10% in HBeAg negative patients). Tenofovir is a nucleotide analogue with more potent antiviral activity. In addition, there is no cross resistance between the two drugs. Therefore it is assumed that tenofovir would be effective in the treatment of chronic hepatitis B patients who shows partial virologic response (detectable HBV DNA by real time PCR after 12 months of treatment) despite treatment with entecavir. In this study, we will compare the efficacy of switching to tenofovir with continuing entecavir in patients who shows partial virologic response to entecavir.
This open-label, single-arm, multicenter study will evaluate the efficacy and safety of adding Pegasys (peginterferon alfa-2a) to nucleos(t)ide analogue (NAs) treatment in patients with HBeAg-negative chronic hepatitis B genotype D showing stable HBV DNA suppression. After a 12-week Lead-in period on treatment with NA, patients with a HBsAg decline <0.5 log10 IU/ml will enter the Add-on period to receive Pegasys 180 mcg subcutaneously weekly for 48 weeks in addition to their current NA treatment. Follow-up will be a further 48 weeks, during which the patients will continue their NA treatment.
This retrospective study will evaluate the association of biomarkers and the treatment response of patients with chronic hepatitis B, who have completed therapy with Pegasys (peginterferon alfa-2a) ± lamivudine. For the analysis stored serum samples obtained from patients will be used; no actual patients are involved.
This cross-sectional multicenter study will evaluate the IL28B polymorphism in patients with HBeAg-negative chronic hepatitis B treated with Pegasys (peginterferon alfa-2a) in the predecessor ML18253 study. The study consists of a single visit where eligible patients will undergo a blood test for IL28B genotyping, with a phone follow-up 7 days after the visit.
