Durham, North CarolinaAges 18 years+ - NCT04779008Recruiting
Remote arm treatment to help blood flow after heart bypass
This trial studies whether a simple, at-home type of treatment using brief arm blood-flow changes can improve blood flow to the heart and outcomes after CABG (heart bypass surgery). It may help some people recover better by protecting the heart around the time of surgery.
Zhengzhou, HenanAges 18–80 - NCT04781322RecruitingPhase 1
Study drug to reduce LDL cholesterol effects in heavy drinkers
This Phase 1 study tests how safe a cholesterol-lowering antibody (alirocumab) is in people who drink heavily but are not seeking alcohol treatment. It also looks at early drug effects in the body to see how it might change cholesterol-related signals.
Bethesda, MarylandAges 21–65 - NCT04785443RecruitingPhase 3
Check whether dye-guided imaging helps find parathyroid glands
This study tests whether using a special camera with a fluorescent dye (called ICG angiography) during total thyroid surgery can help doctors find the parathyroid glands more reliably. It aims to lower the risk of “low parathyroid hormone,” which can lead to low calcium after surgery.
BrestAges 18 years+ - NCT04787744RecruitingPhase 2/Phase 3
Test standard prostate cancer treatment with or without targeted spot radiation
This study tests whether adding targeted local treatment (like radiation to a few spots seen on scans) improves outcomes for some people with limited (oligometastatic) prostate cancer. It compares standard systemic therapy alone versus standard therapy plus PET-scan–guided spot treatment.
Long Beach, CaliforniaAges 18 years+ - NCT04791748Recruiting
Virtual reality balance training for kids with inner-ear problems
This study uses virtual reality tasks to understand and compare balance and movement in children with long-term inner-ear (vestibular) problems versus those without. It may help doctors learn what supports best balance and safety during daily activities.
ParisAges 7 years+ - NCT04793581Recruiting
Testing a small-vessel device for foot circulation problems
This trial checks how well a device called the Pantheris Small Vessel System works to treat blocked small blood vessels in the foot/leg. It may help people improve circulation, but you must meet specific health and follow-up requirements.
Grand Rapids, MichiganAges 18 years+ - NCT04794530RecruitingPhase 3
Cocoa extract trial for walking problems in blocked leg arteries
This Phase 3 study tests whether cocoa extract (cocoa flavanols) can improve walking ability and circulation in people with peripheral artery disease (PAD). It may help people who have PAD-related walking limits and can safely avoid competing cocoa sources and caffeine.
Chicago, IllinoisAges 55 years+ - NCT04796506Recruiting
Tracking sleep changes to improve thinking in Parkinson’s
This study looks at whether changes in “slow wave sleep” (a deep sleep stage) match improvements in thinking for people with Parkinson’s. It uses an exercise/recovery-focused approach and checks sleep and thinking scores to see if these changes go together.
Aurora, ColoradoAges 45–100 - NCT04797286RecruitingPhase 2
Sildenafil for early lung blood-pressure problems in scleroderma
This trial tests whether sildenafil can improve early “high pressure in the lung blood vessels” in people with scleroderma. It may help slow worsening breathing and lung blood-vessel disease before it becomes severe.
New Orleans, LouisianaAges 18 years+ - NCT04799301RecruitingPhase 1
Measure how much sugar you eat using blood and hair samples
This Phase 1 study tests whether “biomarkers” in your blood and hair can accurately measure how much sugar you consume. It may help researchers find better ways to track dietary sugar intake in future nutrition and health studies.
Phoenix, ArizonaAges 18–65 - NCT04802707RecruitingPhase 2
Study drug for mitochondrial depletion disorder due to gene changes
This Phase 2 trial tests a treatment made from deoxynucleosides to help people with mitochondrial depletion disorder caused by certain gene changes. If you match the genetic diagnosis, the study may see whether the treatment improves symptoms or disease markers.
Montreal, QuebecAges 1 month–60 years - NCT04807114Recruiting
Blood or tissue testing to find markers for lung cancer treatment
This study uses detailed “single-cell” testing to look for markers that can predict how well immunotherapy works and what side effects may happen. It is for people with non-small cell lung cancer starting standard first-line treatment.
LeuvenAges 18–120 - NCT04808401Recruiting
Testing how different oxygen levels affect surgery outcomes
This trial studies whether giving higher or lower oxygen during general anesthesia changes heart and lung outcomes after planned (non-emergency) non-heart surgery. It may help doctors choose safer oxygen settings during surgery for people at higher risk for heart problems.
BernAges 18 years+ - NCT04809506Recruiting
Blood and genetic tests to predict future heart problems
This study looks for new body markers (including possible genetic traits) to better predict who is likely to have future cardiovascular events. Your results could help doctors estimate risk and choose prevention strategies more accurately.
ToulouseAges 18–99 - NCT04812314Recruiting
Study how exercise changes body fat and metabolism
This study looks at how starting exercise changes the structure and function of body fat. It may help you understand how exercise affects things like cholesterol and blood sugar, even if you’re not currently exercising regularly.
