Endovascular therapy for large core posterior stroke
This trial tests endovascular therapy (a procedure to remove a clot through a tube in an artery) versus medical management for people with a severe stroke due to a blockage in the back part of the brain (basilar artery) and a large area of brain damage. The goal is to see if the procedure improves outcomes compared to medication alone.

Device follow-up for a small hole in the heart
This follow-up study monitors how well and how safely the Occlutech mVSD device works to close certain muscular heart “holes” (ventricular septal defects). You may join if you already had the device placed and can return for scheduled checkups to help doctors learn long-term outcomes.
DublinAges 3 months–80 years - NCT07278583Recruiting
Heart failure telemonitoring program evaluation
This trial looks at how well a telemonitoring program works for people with heart failure. It checks if the eligibility rules used by the French health authority make sense.
Clermont-FerrandAges 18 years+ - NCT07220226Recruiting
Fontan circulation and venous compression study
This trial looks at how blood flow works in people with Fontan circulation, who have a unique heart surgery. It aims to understand vein compression and may help guide future care.
Dallas, TexasAges 18–45 - NCT07652281RecruitingPhase 1
Study of SHR-5421 for multiple myeloma
This trial tests a new drug, SHR-5421, for people with multiple myeloma that has come back or stopped responding to treatment. It aims to see if the drug is safe and how well it works.

Study of APG-3288 for Relapsed/Refractory Blood Cancers
This trial is testing a new drug called APG-3288 for people with certain relapsed or treatment-resistant blood cancers (like CLL/SLL, DLBCL, MCL, WM, MZL, or FL). You may qualify if you've tried at least 2 prior treatments and are looking for a new option.
Los Angeles, CaliforniaAges 18 years+ - NCT07204938Enrolling by invitationPhase 3
Long-term study of navenibart for hereditary angioedema
This study tests navenibart over a longer period to see if it continues to prevent swelling attacks in people with hereditary angioedema. It is for people who were already in a previous navenibart study.
Scottsdale, ArizonaAges 12 years+ - NCT05503225RecruitingPhase 2
Colchicine for narrowed brain arteries after recent stroke
This Phase 2 trial tests whether colchicine can help people with significant narrowing in brain arteries (from atherosclerosis) after a recent stroke or “mini-stroke.” It aims to reduce the risk related to this condition during the early period after symptoms begin.
Hong KongAges 40–80 - NCT07734506Recruiting
Muscle thickness and sarcopenia in stroke survivors
This study looks at how thigh muscle thickness measured by ultrasound relates to muscle weakness and fear of movement in people who have had a stroke. It may help find better ways to assess muscle health and recovery.
Istanbul, IstanbulAges 40–80 - NCT07149701Recruiting
Ventricular Tachycardia patient registry study
This study is for adults with ventricular tachycardia (a fast heart rhythm) who also have structural heart disease. It will track your health over time to learn more about how this condition is managed.
BeijingAges 18 years+ - NCT07734194Recruiting
Studying a new sedation combo for afib treatment
This trial tests a mild sedation method using remimazolam and fentanyl during a procedure called pulsed-field ablation for atrial fibrillation (afib). It aims to find a safe and effective way to keep you comfortable without deep sedation.
PragueAges 18 years+ - NCT07733960Recruiting
Pacing system study for heart pacing therapy
This trial tests a new pacing system designed to improve how pacemakers work. It may help people who need a pacemaker with left bundle branch area pacing.
Madurai, Tamil NaduAges 18 years+ - NCT03581318Recruiting
Heart MRI study for people with and without heart disease
This study uses magnetic resonance imaging (MRI) to take detailed pictures of the heart. It aims to improve how doctors use heart MRI to diagnose and manage heart conditions.
Bethesda, MarylandAges 7–100 - NCT07734584Recruiting
Reducing air bubbles during aortic repair with carbon dioxide
This trial tests a special flushing method using carbon dioxide gas to prevent air bubbles from entering the bloodstream during a procedure to fix the main artery in the chest. This could help avoid strokes or other complications.
Bologna, ItalyAges 18 years+ - NCT07730879Recruiting
Wall Squat Exercise for Blood Pressure in Sleep Apnea
This study tests whether a simple wall squat exercise can help lower blood pressure in people who have both high blood pressure and sleep apnea (treated with CPAP). If you are using CPAP regularly and are otherwise healthy enough to exercise, this trial may be a good fit for you.
BragaAges 18–80 - NCT07078370Enrolling by invitation
Testing a lab-made blood vessel for heart bypass surgery
This trial tests a lab-made blood vessel (called an ATEV) used as a bypass graft during heart surgery. The ATEV is designed for people who don't have enough healthy leg vein for standard bypass grafts, and it may help restore blood flow to the heart more safely.
