AP1189 Safety and Efficacy for Severe Respiratory Viral Infection
This trial tests whether an experimental drug called AP1189, added to standard hospital care, can help people hospitalized with severe breathing problems from viruses like COVID-19, flu, or RSV. The goal is to see if it reduces the need for mechanical ventilation or other life support.
Mostar, Herzegovina-Neretva CantonAges 18 years+ - NCT07635186RecruitingPhase 2
AHB-137 injection for treatment-naïve chronic hepatitis B
This study tests a new injection called AHB-137 in people with chronic hepatitis B who have never received antiviral treatment. The goal is to see if it can help reduce the hepatitis B virus in the body and improve liver health.
Beijing, Beijing MunicipalityAges 18–65 - NCT07636928RecruitingPhase 1
Study of how the body absorbs a new HIV medicine
This early-stage study tests a new HIV medication (VH4524184) to understand how your body absorbs and processes it. You'll take a single dose of the medication with a small amount of radioactive tracer, which helps researchers track where the drug goes in your body.
GroningenAges 18–55 - NCT06137755RecruitingPhase 1
Shingles vaccine study for healthy adults 50-65
This trial tests a new shingles vaccine in healthy adults aged 50 to 65. Shingles can cause a painful rash, and the vaccine aims to prevent it.
Seoul, Eunpyeong-guAges 50–64 - NCT07634081Recruiting
Testing a new way to collect and mail mpox samples
This trial tests whether special paper strips can safely collect mpox samples from skin lesions and be mailed for testing. If it works, it could make diagnosis faster and easier for patients in remote areas.
BukavuAges Any age - NCT07636733Recruiting
Vitamin D for Gum and Bone Health in Periodontal Disease
This study tests whether vitamin D supplements can reduce inflammation and improve healing in people with gum disease, ranging from mild gingivitis to advanced periodontitis. Researchers will compare how vitamin D affects different stages of gum disease.
RizeAges 18–70 - NCT07633366Recruiting
Understanding ARDS Through Lung Fluid and Imaging Analysis
This study examines lung fluid samples and imaging scans from patients on breathing machines to better understand acute respiratory distress syndrome (ARDS), a serious lung condition. Researchers hope this will help doctors diagnose and treat ARDS more effectively in the future.
Vienna, State of ViennaAges 18 years+ - NCT07636044Recruiting
Shingles Vaccine Response in Lupus Patients
This study tests how well the shingles vaccine (Shingrix) works in people with lupus who take immune-suppressing medications. Researchers want to understand if the vaccine provides good protection in lupus patients, since their immune systems work differently.
SeoulAges 50 years+ - NCT07634913Recruiting
Mobile App for Eye Disease Detection
This study tests a smartphone-based system designed to help detect diseases affecting the front of the eye. Researchers will develop and refine this mobile tool to see if it can accurately identify common eye conditions using photos taken on a phone or with standard eye-examination equipment.
Guangzhou, GuangdongAges 18 years+ - NCT07635368Recruiting
Blood Markers in Newborns With CMV Infection
This research study examines blood samples from newborns to identify biological markers (proteins and genetic signals) that could help detect and understand congenital cytomegalovirus (CMV) infection—a virus some babies are born with. Finding these markers might help doctors identify infected infants earlier and develop better treatments.
CopenhagenAges birth–4 weeks - NCT07637630Recruiting
HPV Vaccine Education for Vietnamese American Parents
This study helps parents in the Vietnamese American community learn about the HPV vaccine, which prevents certain cancers. Researchers will work with you to understand what information helps families decide about vaccinating their children.
Chicago, IllinoisAges 18 years+ - NCT07637877RecruitingPhase 2
Treatments to boost immune recovery in HIV
This study tests new treatments to help people with HIV who have low CD4 counts despite antiretroviral therapy. It aims to improve immune function and reduce the risk of infections.
Beijing, Beijing MunicipalityAges 18–60 - NCT07636551Recruiting
Studying Immune Cells in Healthy Unvaccinated Skin
This study examines special immune cells that live in your skin to understand how they work. Researchers will take small skin samples to learn more about your body's natural defenses, which could help develop better vaccines in the future.
AntwerpAges 18–50 - NCT06393985RecruitingPhase 2
Maintenance therapy after stem cell transplant for B-ALL
This trial tests whether three targeted medicines (decitabine, venetoclax, and blinatumomab) can help prevent leukemia from coming back after a stem cell transplant. It is for people with B-cell ALL who have no detectable remaining leukemia cells and are at least 3 months past transplant.
Suzhou, JiangsuAges 18–65 - NCT06323668Recruiting
