Active clinical trials for "Hepatitis A"

This clinical trial is to clarify and investigate the patterns of immune-related hepatitis and the optimal treatment choice for patients who are steroid-dependent. The project aims to prospectively characterize the various histopathological, biochemical, and phenotypical liver injury patterns induced by immune checkpoint inhibitors and the treatment responses to corticosteroids. Furthermore, the effect of adding a second-line immunosuppressive drug, either MMF in steroid-refractory or steroid-dependent cases will be explored and compared.

Multicenter, Open-label, Single arm Trial with Matched Historical controls. Male and female adults with compensated liver cirrhosis due to chronic hepatitis B virus infection who have low-level viremia. To assess the efficacy of Tenofovir Alafenamide (TAF) in reducing liver-related events (hepatocellular carcinoma, liver-related events and death, decompensated liver cirrhosis) in cirrhotic chronic hepatitis B patients with low-level viremia compared with matched historical controls.

Chronic hepatitis B (CHB) affects 257million individuals worldwide. In 2017, it caused around 39.7 million cases of cirrhosis and 0.4 million cirrhosis-related deaths in 2017. However, there is no specific treatment for liver fibrosis/cirrhosis. Although nucleos(t)ide analogues (NAs) profoundly suppress viral replication, fibrosis/cirrhosis progression can still occur in NA-treated patients. Sodium-glucose cotransporter type-2 (SGLT2) inhibitors are antidiabetic drugs that may prevent fibrosis/cirrhosis progression by reducing hepatic steatosis/inflammation, dampening renin-angiotensin aldosterone system (RAAS) activation, and reducing fluid retention, effects of which are independent of glycemic control. Clinical studies in diabetic patients show SGLT2 inhibitors reduce hepatis steatosis/inflammation, regress ascites (a cirrhotic complication), and improve liver function parameters and survival prognosis in terms of model for end-stage liver disease (MELD) score. There are currently no randomized controlled trials (RCTs) on role of SGLT2 inhibitors in preventing fibrosis/cirrhosis progression in CHB patients. Magnetic resonance elastography (MRE) and transient elastography (TE) are non-invasive techniques for liver stiffness measurement (LSM), although MRE is more accurate than TE. The investigators propose a double-blind, randomized, placebo-controlled trial to compare effect of empagliflozin (an SGLT2 inhibitor) with placebo (1:1 ratio) in preventing fibrosis progression in both diabetic and non-diabetic NA-treated CHB patients with significant/advanced fibrosis or compensated cirrhosis. 108 patients will be randomly sampled from our pre-existing TE database. Empagliflozin 10mg daily will be given to treatment arm. Placebo pills will be manufactured identical in appearance to empagliflozin. Subjects will receive active or placebo pills for three years, and undergo clinical, anthropometric and laboratory assessments (at baseline, weeks 8, 16, and every 4 months thereafter). They will undergo LSM by TE at baseline, end of first, second and third year, and by MRE at baseline and end of third year. Primary outcome is difference in change to liver stiffness (measured by MRE) from baseline between the two groups at the end of third year. The study results will determine whether SGLT2 inhibitors can prevent hepatic fibrosis/cirrhosis progression in NA-treated CHB patients.

This is a randomized, double-blind, placebo-controlled, single (Part A) and repeated dose (Part B) escalation, phase I clinical study to evaluate the safety, pharmacokinetics (PK) and preliminary pharmacodynamics (PD) of RBD1016 in subjects with chronic HBV infection.

This is a phase 2 study in which participants with chronic hepatitis B virus (HBV) infection will receive VIR-2218, VIR-3434 and/or PEG-IFNα and be assessed for safety, tolerability, and efficacy

We will conduct a phase 4, multicenter, open-label trial at 7 academic centers in Taiwan. Chronic hepatitis B patients receiving oral antiviral therapy (entecavir [ETV], tenofovir disoproxil fumarate [TDF]) for at least 2 years, and fulfil the following nucleos(t)ide analogs discontinuation criteria. After nucleos(t)ide analogs discontinuation, patients had a clinical relapse and retreatment regimen switches to TAF. The protocol will be approved by Institutional Review Board (IRB) or Research ethic committee (REC) of each site and will be conducted in accordance with the principles of Declaration of Helsinki and the International Conference on Harmonization for Good Clinical Practice. Each patient provides written informed consent before enrollment.

This project will utilise the notification process as a point of intervention to work with primary practitioners (GP) by contacting them directly when a notification of hepatitis C exposure is received by the Tasmanian department of Health (DoH). A designated role will exist within DoH of a specialist HCV health worker to contact GPs to provide supported assistance in the process of the follow up hepatitis C diagnoses with patients. The study will evaluate whether active follow up of providers with enhanced case management is effective in having patients linked to hepatitis C treatment compared to current standard of care of surveillance for new notifications. The study will also compare the cost-effectiveness of this approach compared to current standard of care after one of their patients is notified with a positive hepatitis C antibody result.

This study is a multicenter, open-label, phase II clinical study in subjects with chronic hepatitis B (CHB), to characterize the safety, tolerability, pharmacokinetic profile and preliminary anti-hepatitis B virus (HBV) efficacy of APG-1387 in combination with entecavir, and to determine the optimal dose of APG-1387 in combination with entecavir.

Hepatitis C Virus (HCV) infection is a global health problem. HCV mainly affects liver cells and causes the liver to become inflamed and damaged. This study will evaluate how safe and effective glecaprevir/pibrentasvir (GLE/PIB) is in adult and adolescent participants with acute HCV infection. GLE/PIB is an approved drug for the treatment of chronic HCV. Around 283 participants at least 12 years of age with acute HCV Infection will be enrolled in approximately 70 sites worldwide. Participants will receive oral tablets of GLE/PIB once daily (QD) for 8 weeks and will be followed for 12 weeks after the end of treatment. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, monitoring for side effects and completing questionnaires.

This is a phase three study to evaluate the safety and efficacy of Pradefovir treatment in chronic hepatitis B patients. Subject will be randomized to Pradefovir group and TDF group at a ratio of 2:1. Treatment duration will be 96w in randomization and followed by 48w in open. The interim analysis will be conducted when all subject completed the first 48-week treatment.
