Active clinical trials for "Hepatitis B, Chronic"

Analysis of effect of anti-TNFα treatment on HBV reactivation among patients with systemic rheumatic disease, especially rheumatoid arthritis

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 participants with HBeAg-negative chronic hepatitis B genotype D showing stable HBV DNA suppression. After a 12-week Lead-in period on treatment with NA, participants 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 participants will continue their NA treatment.

The purpose of this study is to evaluate the safety and efficacy of Entecavir maleate tablets in Chinese patients with hepatitis B

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.

This study will evaluate the efficacy and safety of peginterferon alfa-2a or ADV, in participants with lamivudine-resistant HBeAg-positive chronic hepatitis B. Participants will be randomized to receive either peginterferon alfa-2a for 48 weeks in combination with oral lamivudine for the first 12 weeks, or ADV for 72 weeks in combination with oral lamivudine for the first 12 weeks. The anticipated time on study treatment is 72 weeks, and the target sample size is 255 individuals.

This study will evaluate the efficacy and safety of PEGASYS (peginterferon alfa-2a) in patients with HBeAg positive chronic hepatitis B. Patients will be stratified into group A (treatment naïve patients) or B (YMDD mutant patients). All patients will receive PEGASYS 180 micrograms subcutaneously once weekly for 48 weeks, followed by 24 weeks of treatment-free follow up.

This study aims to clarify whether patients with chronic hepatitis B with high viral load will benefit from oral antiviral therapy despite only mildly elevated serum liver enzyme.

A study demonstrates the non-inferiority of DA-2802 when compared with ㅍViread® in chronic hepatitis B patients

The primary objectives of this study are to evaluate the safety, tolerability, and efficacy of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF)-containing regimens at Week 24 in participants with chronic hepatitis B virus (HBV) infection and Stage 2 or greater chronic kidney disease who have received a liver transplant.

This study is a multicenter, three-part study. Parts 1 and 2 are randomized, investigator- and participant-blinded, placebo-control, single-ascending dose (SAD) and multiple-ascending dose (MAD) study to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of RO7049389 following oral administration in healthy volunteers and chronic HBV infected participants. Part 3 is a non-randomized, non-controlled, open-label part to assess the efficacy and safety of RO7049389 when administered in combination with standard-of-care therapies for up to 48 weeks in nucleos(t)ide (NUC)-suppressed and treatment-naive chronic hepatitis B (CHB) participants.
