Test antibody treatment for chronic hepatitis B
This Phase 1 trial tests HepB mAb19, an antibody medicine, in adults with chronic hepatitis B. The goal is to see how it works and how safe it is in people whose hepatitis B is controlled on current antiviral treatment.
New York, New YorkAges 18–70 - NCT05858502Recruiting
Study immune response to COVID-19 and improve testing
This study looks at how the immune system in the body responds to different COVID-19 virus variants. It may help improve how COVID-19 is diagnosed by comparing people who are currently infected and those who are not.
ParisAges 18–65 - NCT05859074RecruitingPhase 1
Testing MQ710 injections alone or with pembrolizumab for advanced cancers
This early-phase study tests MQ710, a medicine given by injection into a reachable tumor, to see how well it can control advanced cancers. Some participants also receive pembrolizumab, an immunotherapy, to help the immune system fight the cancer.
Basking Ridge, New JerseyAges 18 years+ - NCT05859490RecruitingPhase 1/Phase 2
Yellow fever vaccine study for adults with past vaccination
This trial studies how well the yellow fever vaccine “17D” stimulates the immune system (the body’s germ-fighting response) in adults who were vaccinated with 17D years ago. It may help researchers understand whether a prior vaccination still provides protection and how strong the immune response is.
Portland, OregonAges 20–49 - NCT05860270RecruitingPhase 4
Vitamin D by mouth to prevent peritoneal dialysis peritonitis
This trial tests whether taking vitamin D by mouth can lower the risk of peritonitis (a painful infection of the lining around the abdomen) in people on peritoneal dialysis. You might benefit if your vitamin D level is low and you meet other safety requirements.
Beijing, Beijing MunicipalityAges 19 years+ - NCT05860387Recruiting
Testing faster diagnosis of serious lung fungal infection
This study aims to detect invasive lung aspergillosis earlier by testing samples from your lungs and measuring specific lab markers. It may help doctors start the right antifungal treatment sooner when the infection is suspected.
Havířov, Moravian-Silesian RegionAges 18 years+ - NCT05866523Recruiting
Help for people newly diagnosed with HIV
This study is for adults who were recently diagnosed with HIV and are not yet on HIV treatment (ART). It aims to test ways to support care and help people get connected with the right HIV specialists.
Loma Linda, CaliforniaAges 18 years+ - NCT05866952Recruiting
Breathing and blood-flow testing in long-COVID symptoms
This trial studies how the lungs’ breathing (airflow) and blood flow may be off in people with long-COVID symptoms like tiredness, shortness of breath, or trouble exercising. It may help researchers understand what’s driving symptoms and what kinds of abnormalities could be targeted.
Boston, MassachusettsAges 18–99 - NCT05868239Recruiting
Testing an aerosol box during CPR emergencies
This study tests whether using an aerosol “box” during cardiopulmonary resuscitation (CPR) during an emergency improves safety and care. It’s mainly aimed at trained healthcare staff who can perform required tasks during CPR.
Los Angeles, CaliforniaAges 18–60 - NCT05868733RecruitingPhase 2
Lassa fever vaccine study for people in West Africa
This trial tests an investigational vaccine to prevent Lassa fever, a serious illness found in parts of West Africa. People in different age groups will get the vaccine or a placebo and be followed to see if it’s safe and helps the immune system respond.
AccraAges 1.5 years–70 years - NCT05870969Recruiting
Digital monitoring to catch liver cancer risk early
This study tests a digital (computer/phone-based) system to help track people with higher risk of liver cancer so cancers can be found earlier. It may help by guiding regular check-ins and making early diagnosis more efficient.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05876598Recruiting
Predict bloodstream infection risk using a computer model
This study builds and tests a computer (machine-learning) model to predict bloodstream infections based on what happens in the first days of care. It may help doctors start the right antibiotic faster for patients who truly have an infection.
RomeAges 18 years+ - NCT05878665Recruiting
Low-dose contrast dye for CT scans in suspected appendicitis
This trial tests whether using a smaller amount of contrast dye in a CT scan still gives doctors enough information to diagnose suspected appendicitis. It’s aimed at emergency department patients who are already scheduled for an abdomen and pelvis CT with dye.
SeoulAges 19–44 - NCT05879965Recruiting
Tracking immune responses after mpox, smallpox vaccine, or PrEP
This study follows people after confirmed mpox, after smallpox vaccination, or in people taking HIV PrEP to learn how the immune system responds over time. It may help scientists better understand protection and immune changes after these exposures.
AntwerpAges 18 years+ - NCT05880108Recruiting
Behavior program to help COVID recovery in Veterans
This study tests whether a behavioral (lifestyle) program can improve recovery from COVID-19, especially for Veterans with different body weights. It looks at people who either have never had COVID before or had COVID more than 90 days ago.
Baltimore, MarylandAges Up to 80 years - NCT05880329Recruiting
Diagnosing urinary infections in care home residents
This study tests better ways to figure out whether care home residents have a urinary tract infection (UTI). If you qualify, you may be monitored and asked for urine samples so the team can compare how UTIs are identified.
SouthamptonAges 65 years+ - NCT05881447Recruiting
Study kidney disease patterns in people in Tanzania
This study looks at how common chronic kidney disease is, how it develops over time, and what risk factors are linked to it. It may help improve how kidney disease is recognized and managed in your community.
Bagamoyo, Coast RegionAges 18–99 - NCT05882708RecruitingPhase 4
Ivabradine to slow heart rate in sepsis ICU patients
This study tests whether ivabradine (a heart-rate medicine) can improve blood flow and other vital measurements in adults with sepsis in the ICU. It may help by lowering a fast heart rate when blood pressure is already being supported.
Guangzhou, GuangdongAges 18 years+ - NCT05886816RecruitingPhase 2
Mitoquinone pills to prevent COVID-19 after risky exposure
This trial tests whether an oral medication (mitoquinone/mitoquinol) taken after a high-risk COVID-19 exposure can help prevent you from becoming sick. It is designed for people who currently have no symptoms but had a significant exposure to someone with confirmed COVID-19.
Dallas, TexasAges 18–65 - NCT05890599Recruiting
Yoga or health education for ongoing fatigue after COVID
This trial studies whether a yoga program (compared with health education) can reduce persistent tiredness after COVID-19. It may help if your fatigue has lasted at least 12 weeks and you think it started with COVID.
