Hepatitis D virus infection

This study tests a new drug called GS-4321 for chronic hepatitis delta, a serious liver infection. First, healthy volunteers will help determine safe dosing. Then, people with the disease will receive multiple doses to see if the drug can reduce virus levels and improve liver hea…

This study tests whether switching from the current drug bulevirtide to a new drug called brelovitug can better control chronic hepatitis Delta. About 120 adults who have been on bulevirtide for at least 6 months will take brelovitug for 24 weeks. The main goal is to see if the v…

This phase 3 trial compares a new drug, brelovitug, to an existing treatment (bulevirtide) for chronic hepatitis delta, a serious liver infection. About 172 adults with the infection will receive either drug to see which better controls the virus and normalizes liver enzymes. The…

This Phase 3 trial is testing a new drug called libevitug in 160 people with chronic hepatitis D, a serious liver infection. The goal is to see if libevitug can lower the virus in the blood and improve liver health. Participants receive the drug by IV infusion, and the study comp…

This early-stage trial tests a lab-made antibody (HepB mAb19) in 15 people with chronic hepatitis D, a serious liver infection that requires hepatitis B to survive. The goal is to see if the antibody is safe and can lower virus levels, potentially reducing the risk of liver damag…

This study tests whether giving patients donor-derived immune cells (VSTs) on a regular schedule can prevent dangerous viral infections after a stem cell transplant. 180 participants will be randomly assigned to receive VSTs either on a fixed schedule or only when a virus is dete…

This study tests whether specially grown donor immune cells (viral-specific T-cells) can safely treat viral infections that often occur after a stem cell transplant. These infections can be serious and sometimes don't respond to standard antiviral drugs. The approach aims to boos…

This study evaluates whether a blood test measuring polyreactive immunoglobulin G (pIgG) can more accurately diagnose autoimmune hepatitis (AIH) and distinguish it from other liver conditions. Researchers will collect blood samples from 400 adults undergoing liver biopsy for susp…

This study aims to learn more about liver diseases like hepatitis B, C, and D by observing up to 8,050 participants over time. Participants will have yearly check-ups, blood and urine tests, and liver ultrasounds. Some may be offered experimental treatments if they qualify. The g…

This study aims to collect samples and medical information from people of all ages who have or have been exposed to viral infections, including COVID-19 and herpes. Researchers want to understand how viruses affect healthy individuals versus those with weakened immune systems. Pa…

This study aims to find out how many people with hepatitis B also have hepatitis delta, a more serious liver infection. Researchers will test 244 adults in hospitals, addiction clinics, and prisons in Bergamo, Italy. The goal is to improve detection and understand the true burden…

This study aims to find out how often people with chronic hepatitis B also have hepatitis D, and which types of the virus are most common. Researchers will interview about 2,400 participants and take blood samples to look for links with vaccination history, lifestyle, and other f…

This study in South-East Austria looks at past lab results to find people with hepatitis B, C, or D who may not know they have it. Researchers will invite these individuals to a clinic to discuss treatment options. The goal is to connect them to care and track how many get cured,…

This study looks at the link between gum (periodontal) disease and hepatitis B+D infection, and whether the drug bulevirtide changes that relationship. Researchers will measure inflammation markers in saliva and gum fluid from 25 adults: those with hepatitis B+D on bulevirtide, t…

This study is testing a mobile app called ePro-Diary HDV for people with hepatitis Delta, a rare but serious liver disease. The app helps patients track their health, communicate with doctors, and remember appointments. Researchers want to see if using the app helps patients atte…

This study looks at how the drug bulevirtide changes gut bacteria and bile acids in people with hepatitis delta (a serious liver infection). Researchers will follow 20 patients for 48 weeks, collecting stool and blood samples to see how these changes relate to liver health. The g…

This study collects blood and tissue samples from 800 people with chronic liver disease or liver cancer. Researchers will use these samples to create lab models, such as cell clusters and mouse tumors, to study these diseases and test new treatments. The goal is to improve unders…

This study looks at how the immune system fights hepatitis D in people who also have hepatitis B. Researchers will measure special immune cells (T cells) in 192 adults before and after 12 months of treatment with the drug bulevirtide. The goal is to see if these immune responses …

This observational study aims to develop a rapid T-cell test to help manage patients with chronic hepatitis B (HBV) and hepatitis B/D (HBV/HDV) co-infection. Researchers will analyze immune responses in 300 adult patients to understand how T-cells react to the viruses. The goal i…
