NCT05630820
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.
NCT03587831
Participants meeting study entry criteria are randomized with equal probability to one of two study groups: (1) Lifestyle modification or (2) Vertical Sleeve Gastrectomy (VSG) with Iifestyle modification, followed for 12 months. The primary goal for the trial is to determine if the investigators can recruit, randomize, and retain participants to perform invasive and non-invasive measurements of NASH and fibrosis, deliver lifestyle modification and demonstrate the safety of VSG. The investigators wish to also understand which of these two interventions is more effective in achieving, 12 months after entry into the trial, a reduction in NAS composed of the non-weighted scores: (1) steatosis 0-3 (2) Inflammation 0-3 and (3) ballooning 0-2. Secondary goals include comparing the two treatment groups for changes in other measured outcomes including MRI assessments of intrahepatic triglyceride and liver elasticity and serum markers. As a pilot study, a sample size of 20 in each group should offer significant information as to the difference in NAS score reduction between to two groups and achieve adequate power to distinguish clinically significant changes in the primary and secondary outcome measures. These data support the overarching objective i.e. to provide evidence that a larger, longer-term clinical outcomes trial is feasible. A goal is for a longer term follow up for 5 years to assess the durability of treatment effects and treatment differences.
NCT00326482
This study will provide a basis for research on the impact of liver injury caused by antiretroviral therapy in HIV-infected patients. Elevated liver enzymes called AST and ALT are common in HIV-infected patients taking antiretroviral medications and can indicate liver damage. Although there are a number of possible causes for these elevations, such as infections with a hepatitis virus, antiretroviral medications alone can lead to the elevations. The study will focus particularly on evidence of liver fibrosis, which is a sign of progressive liver damage. HIV-infected patients 18 and older who 1) have been taking combination antiretroviral therapy for at least 12 months and have been on a stable regimen for at least 3 months, and 2) have had elevated AST or ALT levels for at least 6 months may be eligible for this study. Patients who have had liver biopsies performed in the past may be eligible for participation. Participants undergo the following tests and procedures over a 12-month period: * Oral glucose tolerance test: The patient drinks a glucose (sugar) drink. Blood samples are then drawn over 2 hours through an intravenous (IV) line in the patient's arm. This test measures how high the patient's blood sugar and insulin levels rise after drinking a standard glucose load. * Transient elastography: This ultrasound test uses vibration (sound waves) to measure liver stiffness (fibrosis). Vibrations move faster through a fibrotic liver. * Triple-phase CT scan and single slice CT scan of L4-5: Patients fast for 4 hours before the CT scan. A contrast material is injected through a catheter placed in an arm vein to improve the visibility of the liver in the specialized X-ray images obtained in the CT scanner. * Liver biopsy: This test removes a small sample of liver tissue for microscopic examination, particularly for evidence of fibrosis. The skin over the biopsy site is numbed and a needle is passed through the skin and rapidly in and out of the liver. Patients may be given a sedative for the procedure. * Follow-up visits. Patients return for follow-up visits 1 to 4 weeks after the liver biopsy and three more times over the course of the study for a medical history, physical examination and blood tests. Patients may participate in an additional 4-year follow-up, during which they have visits every 3-12 months and are offered the opportunity to repeat the biopsy no sooner than 1 year after the first biopsy. ...
NCT07417553
This trial employs a single-arm, open-label, multicenter clinical trial design. All study participants who meet the inclusion/exclusion criteria will receive Hydronidone treatment for 4 weeks. The study includes a screening period (up to 21 days) to assess the eligibility of participants. Eligible participants will enter the treatment period and receive Hydronidone capsules at a dosage of 270 mg TID (30 mg/capsule, 3 capsules each time, three times daily, taken orally half an hour before meals) for 28 consecutive days. Participants will return for a follow-up visit on Day 28 (±3 days) after the first dose for safety assessments. All adverse events (AEs) and concomitant medications occurring during the study period must be recorded. After the treatment period, participants will enter a follow-up period to monitor any delayed adverse events. Participants who complete the final follow-up visit are considered to have completed the study. Throughout the study, participants must maintain the stability of all their pre-existing treatment regimens, including antiviral therapy and medications for other comorbid conditions.

NCT05272735
Antibodies are the primary mediators of the protection against infection provided by vaccination. Antibodies become most powerful after the B cells that produce them undergo an evolutionary process called affinity maturation, in which antibodies increase their ability to bind to their targets, and thus neutralize pathogens. Affinity maturation occurs in structures within secondary lymphoid organs (for example lymph nodes or tonsils) known as germinal centers. Germinal centers are well known to be triggered by the first dose of vaccines, generating affinity matured plasma cells (B cells that secrete antibody into serum) and memory B cells, which can be converted into plasma cells by booster doses of vaccine. However, it is not fully understood the extent to which memory B cells can return to germinal centers again upon vaccine boosting. Such return would be very important to allow B cells, for example, to adapt to emerging variants of viruses such as influenza or SARS-CoV-2. This study will involve acquiring samples of B cells from germinal centers that form in response to vaccination with the highly effective hepatitis B vaccine. These cells will be analyzed to determine what fraction of them are memory B cells that returned to germinal centers upon boosting, information that is key to knowledge of how vaccine boosters work. Understanding the "rules" that govern how and when memory B cells choose to return to germinal centers in an effective vaccine such hepatitis B could help efforts to develop effective vaccination against more challenging, rapidly mutating viruses, such as influenza, HIV, and hepatitis C.
NCT07265544
The purpose of this observational study is to employ single-cell multi-omics and spatial omics technologies to characterize the spatial and immune structures within the livers of patients with fatty liver, hepatic hemangioma, focal nodular hyperplasia, liver fibrosis, cirrhosis, and HBV infection. The primary questions it aims to address are: Investigate the mechanisms of liver degenerative changes during the processes of liver aging, fatty liver, HBV infection, liver fibrosis, and cirrhosis. Characterize the molecular features and cellular networks at different stages of liver degeneration and identify new targets and mechanisms for the cure of the aforementioned diseases. The study will collect peripheral blood and discarded liver tissue from patients with hepatic hemangioma, fatty liver, HBV infection, liver fibrosis, and cirrhosis who are undergoing hepatectomy or liver biopsy.
NCT07525401
Hepatitis is an inflammatory condition of the liver that has emerged as a significant global health concern due to its widespread prevalence. Data on ursodeoxycholic acid in acute viral hepatitis remain limited. Some studies suggest its positive effect in cholestatic phase of viral hepatitis. UDCA may reduce cholestatic symptoms like jaundice and pruritus potentially shortening hospital stay and improving patient outcomes. However, robust clinical data supporting its routine use in acute viral hepatitis are lacking, and current treatment remains largely supportive. Given the high burden of acute viral hepatitis in our region and the potential for UDCA to improve cholestatic phase of AVH there is a clear need for well-designed clinical studies evaluating its therapeutic role. This study aims to evaluate the role of oral ursodeoxycholic acid in biochemical recovery of patients with acute viral hepatitis. If positive role is confirmed, it will be incorporated in standard treatment and if no role is found unnecessary use will be discouraged. Null Hypothesis (H₀): Oral ursodeoxycholic acid has no significant effect on the bilirubin levels of patients with acute viral hepatitis. H₀: There is no statistically significant difference in bilirubin levels between patients receiving ursodeoxycholic acid and those receiving supportive care alone. Alternative Hypothesis (H₁): Oral ursodeoxycholic acid reduces bilirubin levels in patients with acute viral hepatitis. H₁: There is statistically significant difference in bilirubin levels between patients receiving ursodeoxycholic acid and those receiving supportive care alone.

NCT07503288
Chronic hepatitis C virus (HCV) infection is the second leading cause of primary liver cancer worldwide and the leading cause in the United States. In 2020, an estimate 260,000 deaths were attributable to HCV globally, nearly 80,000 of which occurred in Europe, mainly due to complications such as cirrhosis or hepatocellular carcinoma (HCC). The CARTO-VHC study is a retrospective, observational, multicenter study based on data and samples collected during routine care from 2023 to 2024. The study does not involve direct human participation. The study aims to describe the different genotypes and subtypes of the hepatitis C virus, including unusual subtypes, in a large population of newly diagnosed HCV-positive patients. This will help identify the most common types circulating in France. Additionally, the study will provide a comprehensive understanding of therapeutic failures and drug resistance to direct-acting antivirals (DAA) in treated patients.

NCT06632444
This study is open to adults who are at least 18 years old living with obesity and have: * a confirmed liver disease called non-alcoholic steatohepatitis (NASH)/metabolic associated steatohepatitis (MASH) and * moderate or advanced liver fibrosis People with a history of acute or chronic liver diseases other than MASH or chronic alcohol intake cannot take part in this study. The purpose of this study is to find out whether a medicine called survodutide helps people with MASH and moderate or advanced liver fibrosis improve their liver function. This study has 2 parts. The purpose of the first part of this study is to find out the effect of survodutide on MASH and liver fibrosis. The purpose of the second part is to find out how safe and effective survodutide is in improving liver function. Participants are put into 2 groups randomly, which means by chance. 1 group gets survodutide and 1 group gets placebo. Placebo looks like survodutide but does not contain any medicine. Each participant has twice the chance of getting survodutide. Participants and doctors do not know who is in which group. Participants inject survodutide or placebo under their skin once a week. The survodutide doses are slowly increased until the target dose is reached. All participants receive counselling to make changes to their diet and to exercise regularly. Participants are in the study for up to 7 years. During this time, they regularly visit the study site or have remote visits by video call. For about the first year of the study, participants have these visits every 2 weeks, increasing to every 4 weeks and then every 6 weeks. After being in the study for a little over a year participants will then alternate between visiting the study site or having a remote visit every 3 months until the end of the study. The doctors check participants' health and take note of any unwanted effects. The participants' body weight and effects on the stomach and intestines are regularly measured. At some visits the liver is measured using different imaging methods. At 2 or 3 visits doctors take a small sample of liver tissue (biopsy). The participants also fill in questionnaires about their symptoms and quality of life. The results are compared between the groups to see whether the treatment works.
