Active clinical trials for "Hepatitis B"

The purpose of this study is to evaluate the safety, antiviral activity, and pharmacokinetics of ABI-H0731 in combination with entecavir (ETV) and with ETV plus pegylated-interferon alpha (Peg-IFNα) in Chinese participants with chronic hepatitis B virus infection (cHBV)

A single center, open-label, study to evaluate the intra-hepatic effect of inarigivir dose per day and three times per week on immune response and viral markers in virally suppressed patients with chronic hepatitis B infection

Previous studies indicated that Granulocyte Macrophage-colony Stimulating Factor (GM-CSF) could improve survival rate in patients with acute liver failure and obtain higher HBsAg seroconversion rate when in combination with peg-interferon for chronic hepatitis B (CHB) patients. In this study, investigators will study the clinical effect of entecavir (ETV) plus GM-CSF in patients with CHB compared to ETV monotherapy.

This is an open-label, randomized, multi-part study to evaluate the relative oral bioavailability of a tablet formulation of AL-3778 (formerly NVR 3-778) administered under fasted and fed conditions (Parts 1 and 2) and the drug-drug interaction between AL-3778 and entecavir or tenofovir disoproxil fumarate (Part 3).

The primary objectives of this study are to evaluate the safety and tolerability of the 12 week treatment regimens of inarigivir soproxil plus tenofovir alafenamide (TAF) or commercially available nucleoside/nucleotide (NUC) in adults with chronic hepatitis B (CHB), to evaluate the antiviral activity of 12 weeks of inarigivir soproxil plus TAF versus TAF alone in viremic CHB participants (Groups 1-3, 5), and to evaluate the antiviral activity of 12 weeks of inarigivir soproxil with commercially available NUC(s) in virally suppressed CHB participants (Group 4).

Tenofovir alafenamide (TAF), a novel prodrug of tenofovir (TFV), has been approved for the treatment of chronic hepatitis B virus (HBV) infection. TAF has been shown to be a potent inhibitor of HBV replication at a low dose, with high intracellular concentration and more than 90% lower systemic TFV concentration than tenofovir disoproxil fumarate (TDF). TAF has been approved in the clinical practice guidelines in the west. Since its availability in Asia in 2017, there have been evolving data concerning its positive impact on renal safety as shown in registration trials. The primary objective of this study is to compare the risk of chronic kidney disease (CKD) progression in chronic hepatitis B patients on TAF versus ETV in a territory-wide cohort in Hong Kong.

This is an open-label phase IIa study of HH-003 to evaluate its antiviral activity and safety in subjects with chronic hepatitis B and hepatitis D co-infection. HH-003 is a human monoclonal antibody targeting the pre-S1 domain of the HBV large envelope protein. It blocks engagement of preS1 with sodium taurocholate co-transporting polypeptide (NTCP), the cellular receptor for HBV/HDV.

This is a randomized, double-blinded, placebo-controlled, multi center, dose ranging study of safety and efficacy in volunteers with chronic hepatitis B virus infection. Volunteers will be administered multiple oral doses of ATI-2173 vebicorvir in combination with tenofovir disoproxil fumarate and assessed for safety and efficacy including blood tests to show how the body metabolizes and eliminates the investigational drug as well as how the drug effects the virus infection.

Patients with HBeAG positive, chronic HBV infection will receive either ARC-520 or placebo in combination with entecavir or tenofovir, and be evaluated for safety and efficacy.

The investigators evaluated the safety and efficacy of a short lead-in course (8 weeks) of entecavir followed by combination of entecavir plus peginterferon alfa-2a for 40 weeks.
