Robotic catheter repair for leaky tricuspid heart valve
This trial tests a new robotic catheter procedure to repair a leaky tricuspid valve (the valve on the right side of your heart). Instead of open-heart surgery, doctors thread a tiny device through a vein in your neck to fix the valve. It may be an option if you have severe leaking and your heart team thinks surgery is too risky for you.

GM1 drug added to clot removal for acute stroke
This study tests whether adding a medicine called GM1 to emergency clot-removal surgery helps people recover better from sudden strokes caused by blood clots in major brain arteries. GM1 may protect brain cells from damage during and after the stroke.
Beijing, Beijing MunicipalityAges 18–80 - NCT07519876Recruiting
Blood Clots in the Lungs and Heart Shunts Study
This study looks at whether people with blood clots in their lungs have hidden holes in their hearts that let blood bypass normal circulation. Researchers will use imaging tests to understand this connection and see if it affects how patients do.
Boston, MassachusettsAges 18 years+ - NCT07520045Recruiting
Eye Injections for Diabetic Vision Loss: Two Treatment Comparison
This study compares two injectable medications (faricimab and biosimilar ranibizumab) used to treat diabetic retinopathy, a serious eye condition that can cause vision loss in people with diabetes. The trial will measure how well each medication works and track specific markers in your eye to understand treatment response.
OsijekAges 18 years+ - NCT07520032Recruiting
Shockwave therapy for arm function after stroke
This trial tests whether a non-invasive shockwave treatment can help improve arm movement and strength in people who had their first stroke within the past 6 months. The goal is to see if this therapy reduces stiffness and helps patients regain better use of their arm.
Ajman, Ajman EmirateAges 18–65 - NCT07520656Recruiting
Heart Valve Surgery and Sleep Breathing Problems
This study looks at whether fixing heart valve problems with minimally invasive procedures (TAVI or MTEER) can improve sleep-related breathing issues. Researchers will monitor your sleep patterns before and after your scheduled heart valve procedure.
Athens, AtticaAges 18 years+ - NCT07521436Recruiting
Understanding Heart Disease Risk Awareness in Men and Women
This study asks people who have had heart or blood vessel problems about their understanding of risk factors and how they view their cardiovascular health. Researchers want to learn whether men and women perceive their heart disease risk differently.
MilanAges 18 years+ - NCT07521800Recruiting
Remote Heart Monitoring After Aortic Valve Replacement
This study tests whether monitoring your heart rhythm at home using a portable ECG device after your aortic valve replacement procedure (TAVI) helps catch problems early. Researchers want to see if remote monitoring is safe and helpful for patients recovering from this procedure.
TurinAges 18 years+ - NCT07522203Recruiting
Heart Function Recovery After Balloon Angioplasty for Lung Blood Clots
This study looks at how a minimally invasive procedure called balloon pulmonary angioplasty (BPA) helps patients with chronic blood clots in the lungs improve their heart function and overall recovery. Researchers will measure blood flow patterns in your arteries before and after the procedure to understand how well your heart recovers.
IstanbulAges 18–85 - NCT07523269Recruiting
Testing a Blood Pressure Bracelet for Daily Monitoring
This study tests whether wearing an Aktiia bracelet for 6 months can help doctors better understand and control your blood pressure. You'll wear the bracelet daily and visit the clinic twice to see if this wearable device helps manage high blood pressure that isn't controlled by current medications.
Boston, MassachusettsAges 21–85 - NCT07523503Recruiting
One-sided vs. both-sides arm training after stroke
This study compares two ways of doing hand and arm exercises after stroke: practicing with just your weak arm, or practicing with both arms together. The goal is to see which approach helps you regain better movement, strength, and hand coordination.
Kot AdduAges 40–75 - NCT07523555RecruitingPhase 1/Phase 2
Dual-Target CAR-T Cells for Blood Cancers That Haven't Responded to Treatment
This study tests a new type of cell therapy called CAR-T cells that are designed to target two different proteins on cancer cells. These cells are made from your own immune cells, trained in the lab, and then put back into your body to fight blood cancers that have come back or stopped responding to previous treatments.
Shenzhen, GuangdongAges 18–75 - NCT07523646RecruitingPhase 4
Blood Boost for Patients With Heart Valve Infections
This study tests whether giving iron and a blood-boosting medicine (EPO) helps patients with bacterial heart valve infections who have low red blood cells. The goal is to see if it speeds recovery and improves how patients feel.
CopenhagenAges 18 years+ - NCT07523880Recruiting
Blood Markers Study for Heart Disease and Blood Clot Risk
This study examines new blood markers to predict blood clot and bleeding risks in patients with heart disease taking blood thinners. Understanding these markers may help doctors better predict complications and adjust treatment for individual patients.

MTS109 for Hard-to-Treat Autoimmune Diseases
This early-stage trial tests a new treatment called MTS109 for autoimmune diseases (like lupus, muscle inflammation, scleroderma, vasculitis, or Sjögren's syndrome) that haven't responded well to standard medications. The goal is to see if MTS109 can help control disease that keeps flaring or getting worse despite current treatments.
