Leicester, LeicestershireAges 65 years+ - NCT05801224Recruiting
Inhaled nitric oxide for lung injury in intensive care
This study tests whether giving inhaled nitric oxide gas helps improve lung function in patients on a breathing tube with mild to moderate acute lung injury (ARDS). Participants will receive standard care plus the study gas, and the team will use special imaging to see how the lungs respond.
Boston, MassachusettsAges 18–80 - NCT05711849RecruitingPhase 2
Stem cell treatment for long-lasting chest pain not helped by meds
This Phase 2 trial tests whether stem cells placed into the heart artery can safely reduce symptoms in people with “refractory” angina (chest pain) despite maximum heart-healthy medication. You may qualify if your chest pain is limiting your activity and other heart procedures (stents/bypass) aren’t possible or are too risky.
London, EnglandAges 18 years+ - NCT05708430RecruitingPhase 2
Test stem-cell mixture injection for painful thumb arthritis
This Phase 2 study tests how safe an injection made from your own body fat cells (stroma vascular fraction) is in people with painful arthritis at the base of the thumb. It also looks at whether pain and hand function improve after the injection.
AmiensAges 18 years+ - NCT05704309Enrolling by invitation
Study of diabetes prevention participants using brain scans
This study looks at how people who previously took part in a diabetes prevention program are doing over time, including brain health using MRI scans for some participants. It may help researchers understand who is at higher risk for memory and thinking problems and why.
Phoenix, ArizonaAges Any age - NCT05663216Recruiting
Study of fluid leaks in serious whole-body inflammation
This trial looks at what causes blood vessels to “leak” fluid during a dangerous whole-body inflammation response. It may help doctors understand why some people develop fluid buildup and aim for better monitoring and care in the ICU.
ParisAges 18 years+ - NCT05628948Recruiting
Donate blood for a heart and metabolism research biobank
This study builds a “biobank,” which is a collection of blood and related samples, to support future research on heart and metabolic (sugar/body-fat) conditions. It may help researchers better understand these diseases and improve future prevention and treatments.
Cleveland, OhioAges 18 years+ - NCT05628779Enrolling by invitation
Clip procedure to repair a leaking tricuspid valve
This trial studies a minimally invasive “edge-to-edge” clip procedure to reduce severe leakage of the tricuspid valve. It’s for people who still feel unwell despite standard treatments and may be too high-risk for open-heart surgery.
AmsterdamAges 18 years+ - NCT05561361Recruiting
Test treatment for primary aldosteronism and blood vessel function
This trial studies whether a specific treatment (related to spironolactone/aldosterone support) can improve how well your blood vessels work in people with primary aldosteronism. It may help reduce blood pressure risk by improving blood vessel health.
NanchangAges 18–75 - NCT05483465RecruitingPhase 4
NAD supplement trial for brain blood vessel health in aging
This trial studies whether taking an NAD supplement can support brain blood vessel health as people age. Participants will be tested for brain and health changes and may help researchers understand how to keep the brain’s blood vessels healthier over time.
Oklahoma City, OklahomaAges 60–85 - NCT05498116RecruitingPhase 4
Montelukast to improve kidney and blood vessel function in type 1 diabetes
This trial tests whether montelukast, a medicine commonly used for allergies, can improve kidney health and blood vessel function in adults with long-term type 1 diabetes. You may join a treatment group and have kidney and circulation measurements taken over the study period.
Aurora, ColoradoAges 18–80 - NCT05440422RecruitingPhase 2
Anifrolumab for heart health in lupus patients
This study tests whether anifrolumab, a drug that targets the immune system, can improve markers of blood vessel health in people with lupus. It may help reduce the risk of heart problems associated with lupus.
Bethesda, MarylandAges 18–80 - NCT05454267Recruiting
Study early blood vessel changes from vaping
This study looks for early signs of blood vessel problems in people who vape and in healthy non-vapers. It may help researchers find ways to detect and prevent vaping-related vascular disease early.
Miami, FloridaAges 18–40 - NCT05433129Recruiting
Test of brain blood-flow control using near-infrared light
This study uses a non-invasive light test on the forehead to measure how your brain regulates its blood flow. It’s meant to help researchers understand brain circulation control in healthy people.
Winnipeg, ManitobaAges 18 years+ - NCT05427084RecruitingPhase 2/Phase 3
Canagliflozin to reduce inflammation in heart artery disease
This trial tests canagliflozin to see if it lowers “vascular inflammation” in people with diabetes and stable coronary artery disease. It may help reduce harmful inflammation signals that can raise future heart risk.
Ottawa, OntarioAges 18 years+ - NCT05403151Recruiting
Healthy blood vessel and control study
This study looks at healthy adults and how their blood vessels work. It may help researchers understand normal circulation so they can better compare changes in future conditions.
