Active clinical trials for "Hepatitis D"

Background: Chronic hepatitis D is a serious liver disease caused by a virus. Currently, no medications are approved to treat chronic hepatitis D. Objective: To test a combination of 3 drugs in people with chronic hepatitis D. Eligibility: People 18 years or older with chronic hepatitis D. Design: Participants will be in the study about 2 years. They will have 3 inpatient stays of 3 to 5 days. Participants will be screened. They will have a physical exam with blood tests. They will have a test of their heart function and an ultrasound: a wand that uses sound waves to create images of the liver will be rubbed over the skin on their torso. Participants will stay in the clinic for a 3-day baseline visit. They will have imaging scans, an eye exam, and a visit with a reproductive specialist. They will have a liver biopsy: about 1 inch of liver tissue will be removed, either with a tube inserted through a vein in the neck, or with a needle inserted through the participant s side. Participants will take the study drugs for 48 weeks. Two of them are tablets taken twice a day at home; 1 is a shot administered once a week. Participants will begin taking the drugs during a 5-day stay in the clinic. Then they will have 15 outpatient visits while taking the drugs and 7 more after they finish. The last 3-day clinic stay will be 6 months after participants finish taking the drugs. The liver biopsy, imaging scans, and other tests will be repeated.

This study aims to assess the efficacy and safety of bulevirtide (BLV) in chronic hepatitis D patients treated in Greek liver centers.

The aim of study is to evaluate the current prevalence of HDV infection, and comprehensively analyze the interaction between HDV and HBV infections in the era of NAs in Taiwan. Investigators plan to set up a platform for HDV positive patients in Taiwan to invite sites or hepatologists who are interested in this field.

Background: The COVID-19 global pandemic killed more than 6 million people worldwide. Several vaccines have been developed against the virus that causes this disease. These vaccines are effective at preventing severe symptoms and death from COVID-19. Some people with chronic liver disease, especially those with an advanced condition called cirrhosis, do not respond to many vaccines as well as healthy people do. The goal of this natural history study is to find out how well people with chronic liver disease respond to the COVID-19 vaccines. Objective: To learn how chronic liver disease affects the body s immune response to vaccination against COVID-19. Eligibility: People aged 18 years or older with chronic liver disease. They must also be enrolled in protocol 91-DK-0214 or 18-DK-0091. Design: Participants will have 3 visits, each spaced 6 months apart. Each visit will last 2 hours. Participants will have their vital signs recorded. These include age, sex, race, height, and weight. They will give their medical history. At each visit, participants will have blood drawn through a needle inserted into a vein in the arm. The sample drawn at each visit will be from 1 to 8 tablespoons. At each visit, participants will fill out a questionnaire. They will answer questions about whether they have been vaccinated against COVID-19; whether they have had COVID-19; and whether they have been exposed to someone who had COVID-19. The questionnaire will take 10 to 15 minutes. Researchers will also look at results of past blood tests from other research studies.

The aim is to assess the efficacy and specific safety in an observational study of patients with Chronic hepatitis D (CHD) with prospective follow-up, with antiviral treatment of 2 mg Bulevirtide (BLV) +/- PEG-IFNα-2a and +/- NA given as part of the patient's routine medical care. Also, explorative endpoints of biomarkers in peripheral blood, saliva, fecal sample and/or intrahepatic markers/signatures, and quality of life outcomes will be assessed.

This is a prospective, multicentric, non comparative study, with a retrospective data collection aiming at evaluating the efficacy and safety of bulevirtide in patients with chronic HBV/HDV co-infection with severe fibrosis injuries, or moderate fibrosis injuries associated with persistent increase of ALT.

Portal hypertension (PH) is one of the key drivers of clinical deteoration in patients with liver cirrhosis. It has been demonstrated that antiviral therapy in patients with chronic hepatitis C infection leads to a decrease of PH and is associated with an improved outcome. Recently, Bulevirtide was approved for the treatment of patients coinfected with hepatitis B (HBV) and chronic hepatitis delta (HDV) infection, which helps to achieve viral supression in these patients. This study investigates the potential effects of viral supression on PH in patients with chronic HBV/HDV infection and liver cirrhosis.

The circulation of the Hepatitis D Virus (HDV) has considerably diminished in Italy, secondary to the control of the Hepatitis B Virus (HBV) with vaccination; this has led to the perception that HDV is vanishing and has reduced attention to the diagnosis of Hepatitis D. However, migratory fluxes from HDV endemic areas, fostered by labour-forces globalization, are increasingly reconstituting the reservoir of HDV in the country and hepatitis D has not yet vanished in native Italians but will remain an important medical issue for several years to come. As the epidemiologic and clinical features of HDV infection in migrant communities are largely unknown and the features of native Italians with long standing HDV infections have not been updated, this project intends to establish the contemporary epidemiological and medical context of HDV in immigrants in Italy and to determine the clinical characteristics and needs of the residual cohort of native HDV Italians, through the analysis of all HDV cases recruited in 12 months in a coordinated network of 35 Italian medical centers. The data will provide an appraisal of the burden of hepatitis D in the country and of its impact on the National Health System. They will present the paradigm of the current trend of HDV infection in high-income countries in the world.

A phase 2a clinical Study of Hepalatide for Injection in Subjects with Chronic Hepatitis D

This is an open-label, randomized, multi-center study in patients with chronic HBV and HDV co-infection.
