Active clinical trials for "Hepatitis B"

To compare the efficacy and renal safety of tenofovir alafenamide (TAF) versus entecavir (ETV) in the chronic hepatitis B patients.

This is a first-in-human, placebo-controlled, single dose, dose-escalation phase 1 study to evaluate the safety, pharmacokinetics and antiviral activity of a highly potent neutralizing anti-HBV monoclonal antibody (mAb), HepB mAb19, which targets the S-protein in individuals with chronic hepatitis B (CHB) on nucleos(t)ide analog therapy (NRTI).

The study aims to demonstrate that antiviral therapy for patients with immune tolerance of CHB. On the basis of the original antiviral therapy of entecavir, further clarify the safety and effectiveness of entecavir combined with tenofovir amibufenamide.The investigators plan to enroll about 328 hepatitis B patients,. who are in the stage of immune tolerance. These participants will be devided into two groups randomly .Group A will receive the treatment of entecavir. Group B will be treated with entecavir and tenofovir amibufenamide. The participants in both groups will be followed up for 96 weeks. The primary endpoint is to compare the inhibition rate of HBV-DNA between two groups. The secondary endpoint includes: (1) Comparing the decrease of HBV DNA at 48 weeks between the two groups. (2) Comparing the HBeAg seroconversion rates at 48 weeks and 96 weeks between the two groups. (3) The changes of HBsAg at 48 weeks and 96 weeks between the two groups. (4) Comparing adverse side effects between the two groups.

This Phase 1/2a multiple part study is a first time-in-human (FTIH) study designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of single (Part 1) and repeat doses (Part 2) of GSK3965193 in healthy participants. Part 3 will evaluate the ability of GSK3965193 to lower hepatitis B virus surface antigen (HBsAg) in participants living with chronic hepatitis B infection (PLWCHB). Part 4 will evaluate the safety and tolerability of combination therapy with GSK3965193 and bepirovirsen and the potential to effect sustained virologic response in PLWCHB.

This is an open-label study to determine the efficacy, safety, tolerability and immunogenicity of ChAdOx1-HBV and MVA-HBV, together VTP-300, in combination with low-dose nivolumab, in patients with chronic HBV who are virally suppressed with oral anti-viral therapies.

Enroll patients who are pre-treated with Entecavir at least 24 weeks and confirmed HBV antiviral (HBV DNA <69 IU/mL) effects. Subjects are given one test drug or comparator once a day for 48 weeks according to the results of random assignments, and their HBV antiviral inhibitory effect and safety are evaluated at 24 and 48 weeks visits.

IMC-I109V is an immune-mobilizing monoclonal T cell receptor (TCR) against viruses (ImmTAV®), a new class of bispecific protein therapeutics designed for the treatment of chronic hepatitis B virus (HBV) infection (CHB). This is the first in-human study of IMC-I109V in persons with CHB.

This trial is a multi-center, open, single-dose, dose-increasing trial，to evaluate the safety and efficacy of STSG-0002 injection in patients with chronic hepatitis B treated with oral antiviral therapy.

This is a first in human (FIH), multi-center, dose-finding, and dose-escalation Phase I clinical study of RO7565020 to investigate the safety and tolerability and to characterize the pharmacokinetics and pharmacodynamics following single and/or multiple doses of RO7565020 in healthy participants and/or virologically suppressed participants with chronic hepatitis B (CHB).

This study is intended to confirm the efficacy, safety, pharmacokinetic (PK) profile, and the durability of hepatitis B virus surface antigen (HBsAg) suppression observed with bepirovirsen for 24 weeks (with loading doses) as compared to the placebo arm. This study will have 4 stages: a) Double-blind treatment (bepirovirsen or placebo) for 24 weeks. b) Nucleos(t)ide analogue (NA) treatment for 24 weeks. c) NA cessation stage OR Continue NA for 24 weeks. d) Durability of response and follow up for further 24 weeks for participants who stopped NA treatment at Week 48. The arms will be stratified based on HBsAg level (HBsAg greater than or equal to [≥] 100 international unit per milliliter [IU/mL] to less than or equal [≤]1000 IU/mL or greater than [>] 1000 IU/mL to ≤3000 IU/mL) at screening. The total duration of the study, including screening (up to 60 days), the double-blind treatment stage (24 weeks), the On NA only stage (24 weeks), and the NA cessation and durability stages (48 weeks) is up to approximately 104 weeks at maximum for each participant.
