Botulinum injections for lower leg exertional muscle pressure pain
This trial studies whether injecting botulinum (a medicine that relaxes overactive muscles) into the lower leg can reduce pain and pressure during exercise in people with a confirmed condition called chronic exertional compartment syndrome. It may help by lowering the muscle compartment pressure that builds up after activity.

LDL cholesterol study in people 75+ with heart or blood vessel disease
This trial studies how to lower “bad” cholesterol (LDL) in people age 75 and older who have already had heart, brain, or leg/blood-vessel problems from blocked arteries. The goal is to see if the approach helps prevent further cardiovascular events (like heart attack or stroke).
Beijing, Beijing MunicipalityAges 75 years+ - NCT05766059Recruiting
Noninvasive brain stimulation to aid stroke or phantom limb pain rehab
This trial tests new, noninvasive brain stimulation techniques to help recovery after stroke weakness or after arm amputation with phantom limb pain. If you fit the type and timing of your condition, the study may help improve pain or hand/arm function without surgery.

Apremilast study for children with mouth ulcers from Behçet’s
This trial studies whether apremilast can help reduce mouth ulcers in children who have Behçet’s disease or juvenile psoriatic arthritis. You may be considered if your child finished a main study and is under 18, and can safely continue treatment.
ThessalonikiAges 5–18 - NCT05767476Recruiting
Testing cooling treatment after lack of oxygen at birth
This trial studies outcomes in newborns who had breathing problems from low oxygen before or during birth and were treated with a cooling therapy (therapeutic hypothermia). It may help doctors understand which babies benefit most and what recovery looks like over time.
RomeAges 10 minutes–6 hours - NCT05767619Recruiting
Digital tool to guide care for chest pain calls
This trial tests a digital decision-support tool that helps emergency teams manage people who call for help because of chest pain. It may improve how safely and consistently chest pain is assessed and treated in the ambulance setting.
Kungsbacka, Region HallandAges 18 years+ - NCT05768178RecruitingPhase 2/Phase 3
Vemurafenib plus cobimetinib for BRAF-mutant cancers
This trial tests whether combining two targeted cancer medicines—vemurafenib and cobimetinib—can treat adults whose tumors have a specific “BRAF V600” mutation. You may be screened with blood tests and a tissue biopsy before starting treatment.
BelfastAges 18 years+ - NCT05769036Recruiting
Biventricular vs left bundle pacing for heart failure outcomes
This trial compares two types of heart pacing to see which improves outcomes for people with heart failure. It may help those who need pacing to better coordinate heartbeats and relieve symptoms.
TomskAges 18–80 - NCT05770349Recruiting
Heart failure patients having bypass surgery are studied
This study looks at tiny structures inside heart muscle cells (especially “power stations” in the cells) in people with certain types of heart failure who are getting coronary bypass surgery. It may help researchers better understand what changes happen in the heart and how this could guide future care.
TomskAges 18 years+ - NCT05770687Recruiting
Testing diabetes heart medicine soon after a heart attack
This study looks at how starting an SGLT2 inhibitor (a diabetes medicine) around the time of a heart attack affects heart outcomes and heart muscle changes over time. It may help you and your care team understand whether this timing is beneficial after a PCI procedure.
SeoulAges 19 years+ - NCT05773638Recruiting
Study blood clots and heart disease in adults with Von Willebrand
This study looks at cardiovascular problems and blood-clot events (like deep vein clots or pulmonary embolism) in adults with Von Willebrand disease in western France. It may help doctors better understand who is at risk and how to manage these complications.
AngersAges 18 years+ - NCT05773768Recruiting
Care pathway study for newly diagnosed atrial fibrillation patients
This study looks at new care plans (“care pathways”) and how well they work, including cost and health outcomes. It may help by comparing whether a different follow-up approach after a new atrial fibrillation diagnosis leads to better care, especially for older adults.
GroningenAges 65 years+ - NCT05774262Recruiting
Pacemaker or nerve-targeting treatment for certain heart rhythm blocks
This study compares two treatments for specific “AV block” heart rhythm problems: a pacemaker versus a procedure called cardioneuroablation. The goal is to see which approach works better for preventing symptoms like fainting or slow heart rates.
Dąbrowa GórniczaAges 18–75 - NCT05774288Recruiting
Testing a device to close a heart opening called PFO
This trial studies whether a Cera™ device is safe and effective for closing a patent foramen ovale (PFO), a small hole in the heart. It is for adults whose PFO is linked to certain types of stroke or ongoing clot-related events.
Beijing, Beijing MunicipalityAges 18–60 - NCT05774938Recruiting
Quality of life after minimally invasive aortic repair
This study looks at how people’s quality of life changes after a planned minimally invasive procedure to repair the aorta using EVAR, FEVAR, or BEVAR. It may help doctors better understand what recovery and day-to-day wellbeing are like for patients after this kind of treatment.
StockholmAges 18 years+ - NCT05775445Recruiting
People with very blocked or very normal coronary arteries
This study compares people with very severe coronary artery disease to those without significant disease, using heart imaging data. It aims to understand what differs between extreme cases and how that information could guide future care.
SingaporeAges 21–99 - NCT05775432Recruiting
Study outcomes for people receiving heart transplants
This study follows people with severe (end-stage) heart failure who are evaluated for and receive a heart transplant. It helps doctors understand what outcomes to expect after transplant, which can guide future care.

Los Angeles, CaliforniaAges 12–60 - NCT05776212Recruiting
Imaging study for certain heart amyloidosis types and heart thickening
This trial uses special heart imaging to better measure how amyloid deposits affect the heart in people with certain diagnoses. The goal is to understand which imaging signals match your disease and to see if this approach could help guide care.
GroningenAges 40 years+ - NCT05776797Recruiting
Ablation vs best medicines for CRT patients with permanent atrial fibrillation
This trial compares two approaches—an AV junction ablation procedure versus continued best medical treatment—in people who already have a heart device for heart failure (CRT) but still have ongoing permanent atrial fibrillation. It aims to improve how well your heart rhythm is controlled and how effectively the device can pace your heart.
