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+ - 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+ - 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 - NCT05910268Recruiting
Study of HIV care training for clinic teams
This study looks at how HIV care can be improved by collecting feedback from clinic staff and leaders who participate in a training program. It may help shape better support and education for nurses, doctors, and primary care teams.
New Haven, ConnecticutAges 18 years+ - NCT05910580Recruiting
Screening and support for alcohol and substance risk in adults
This study aims to improve care access and outcomes for adults who screen positive for risky alcohol or drug use. If you qualify, you may be offered ways to connect to support during your reproductive years.
Boston, MassachusettsAges 18 years+ - NCT05887557Recruiting
Mobile HIV care for people struggling to stay in treatment
This study tests a low-barrier, mobile HIV care program designed with input from patients and other stakeholders to help people stay engaged in care and reach an undetectable viral load. It may help if you’re having trouble keeping regular HIV appointments or staying on treatment.
Oakland, CaliforniaAges 15 years+ - NCT05889806Enrolling by invitation
Study uses blood and tissue samples for gene and protein testing
This study collects and analyzes your donated samples (like blood or other biospecimens) to look for patterns in genes and proteins. The results may help researchers understand disease biology and improve future tests or treatments.
New Orleans, LouisianaAges 18 years+ - NCT05908682Recruiting
Study of ibrexafungerp safety during pregnancy
This study looks at what happens when ibrexafungerp is taken during pregnancy, including outcomes for the baby. You may join if you were exposed to this medicine during pregnancy (or very close to conception) and you agree to share information and complete study follow-up.
New Delhi, Vasant ViharAges birth+ - NCT05890612Recruiting
Study of Paxlovid safety and effectiveness in high-risk COVID-19
This study observes people at higher risk for severe COVID-19 who take Paxlovid, to better understand how well it works and how safe it is in real-world use. It may help doctors confirm the best way to use Paxlovid and spot any side effects.
SeoulAges 19 years+ - NCT04611022Recruiting
Help increase HPV vaccine completion in Denver families
This study tests an educational program to help people in Denver who have not yet started the HPV vaccine (or haven’t finished it) complete the vaccine series. It may help families understand the vaccine and follow through with completing the recommended doses.
Denver, ColoradoAges 18 years+ - NCT05849467RecruitingPhase 1
Testing how the brain absorbs anti–CD8 therapy in nervous system disease
This Phase 1 study tests a small drug (called an anti–CD8+ T cell minibody) to see how much reaches the brain. It may help researchers understand how to deliver similar treatments for multiple sclerosis, progressive multifocal leukoencephalopathy (PML), or other brain inflammation when the brain’s protective barrier is “open.”
Bethesda, MarylandAges 18–120 - NCT05860231Recruiting
Comparing two catheters for long-term bladder drainage
This study compares two types of catheters for people who need long-term bladder drainage. It tests if a new valve-style catheter works as well as the standard one.
Santa Cruz de Tenerife, TenerifeAges 18 years+ - NCT05852158RecruitingPhase 4
Antibiotics to prevent infection after jaw surgery
This trial tests whether giving antibiotics can lower the chance of infection after orthognathic (jaw) surgery. It may help by preventing post-surgery infections, but participation depends on your health history and medication allergies.
Halifax, Nova ScotiaAges 16 years+ - NCT05855330RecruitingPhase 2
Arginine treatment for kids hospitalized with COVID-19
This Phase 2 trial tests whether replacing the body’s arginine (an amino acid) can improve outcomes for children and young adults hospitalized with COVID-19. It may help the immune response, but you must meet several safety criteria to join.
Atlanta, GeorgiaAges 3–21 - NCT05848713RecruitingPhase 3
Blood-thinner treatment for complications of community pneumonia
This Phase 3 trial tests whether an anti-clot “blood thinner” can reduce complications from community-acquired pneumonia in hospitalized adults who need extra oxygen. It may help by lowering harmful clot-related effects during serious lung infection.
Chicago, IllinoisAges 18 years+ - NCT05849038RecruitingPhase 2
Treating inflammation to improve depression in HIV
This Phase 2 study looks at whether lowering inflammation can help improve depression symptoms in adults living with HIV. You may be able to join if your HIV is well controlled and you are currently experiencing major depression (or a certain type of bipolar depression).
Atlanta, GeorgiaAges 18–65 - NCT05854563Recruiting
Study using collected cough samples to learn about lung disease
This trial looks at “cough capture” samples to better understand what is happening in the lungs. You might be eligible if you’re having a bronchoscopy for medical reasons and don’t already have lung cancer.
The Bronx, New YorkAges 21 years+ - 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+ - NCT05875740Recruiting
Memory T cells and sepsis severity study
This study looks at a type of immune cell called 'memory CD8+ T cells' in patients with sepsis, a life-threatening response to infection. The goal is to see if these cells are linked to how severe the sepsis is and the risk of dying. This may help doctors better predict outcomes for people with sepsis.
Wuhan, HubeiAges 18–60 - NCT05866523Recruiting
