AndriaAges Any age - NCT05065216RecruitingPhase 2/Phase 3
Study drug for acute ischemic stroke started within 24 hours
This trial tests whether an investigational study drug can improve outcomes after an acute ischemic stroke (a stroke caused by blocked blood flow). You may be eligible if you are able to start treatment quickly after symptom onset and have a moderate stroke severity on a standard stroke exam.

Digital therapy for depression and thinking problems after stroke
This Phase 2 trial tests a smartphone/tablet-based program to improve post-stroke depression and executive thinking skills (like planning and attention). It may help if you have ongoing depressive symptoms and thinking/executive difficulties at least 6 months after your first stroke.
New York, New YorkAges 50–79 - NCT05903950Recruiting
Air pollution study to help lower blood pressure
This trial tests whether an air-pollution–reduction approach in your home can help lower blood pressure. It focuses on adults with mildly high blood pressure and certain metabolic health markers.
DohaAges 18–60 - NCT06511505Recruiting
Testing AI to find hidden heart conditions from ECGs
This study uses an AI tool to look at your ECG (a simple heart test) to help find early signs of atrial fibrillation (an irregular heartbeat) or structural heart disease (changes in heart structure). It aims to see if the AI can help doctors catch these conditions sooner, even in people who don't yet have symptoms.
Chicago, IllinoisAges 40 years+ - NCT04474847RecruitingPhase 3
Abatacept for giant cell arteritis treatment
This Phase 3 trial tests abatacept to treat giant cell arteritis (GCA), a blood vessel inflammation that can cause headaches and vision risk. It’s for people with newly diagnosed or returning (relapsing) GCA with active symptoms in the last 8 weeks.
Rochester, MinnesotaAges 50 years+ - NCT06469814Enrolling by invitation
Heart failure snapshot study
This study is a snapshot of patients with heart failure and aims to better understand how heart failure is managed in different settings, from outpatient care to emergency treatment.
YerevanAges 18 years+ - NCT07539298RecruitingPhase 2/Phase 3
Valsartan for Heart-Related Mitral Valve Leaking
This study tests whether a blood pressure medication called valsartan can reduce leaking in the mitral valve (a valve in your heart) caused by an enlarged left chamber. The goal is to see if this medication can improve heart function and reduce symptoms without needing surgery.
Québec, QuebecAges 18–85 - NCT07609940RecruitingPhase 4
Linvoseltamab plus tocilizumab for heavily treated multiple myeloma
This trial tests a combination of two drugs (linvoseltamab and tocilizumab) for adults with multiple myeloma that has stopped responding to standard treatments. Tocilizumab is added to help reduce serious side effects from the main drug.
Los Angeles, CaliforniaAges 18 years+ - NCT03217006Recruiting
Compare one vs multiple heart artery grafts for bypass
This study looks at whether using one artery graft or multiple artery grafts during heart bypass surgery works better for people with specific coronary artery disease. You may be randomized to one approach, and the trial team will follow outcomes after surgery.
Boulder, ColoradoAges 18–70 - NCT07064473RecruitingPhase 3
Testing vicadrostat plus empagliflozin for diabetes, high blood pressure, and heart disease
This study tests a new pill called vicadrostat taken with another medicine (empagliflozin) to see if it helps people with type 2 diabetes, high blood pressure, and heart disease. It may reduce the risk of heart problems, but you must not have had heart failure or use certain other heart medications.
Anniston, AlabamaAges 18 years+ - NCT06660732RecruitingPhase 2
Study of Rilonacept for cardiac sarcoidosis
This trial tests if rilonacept can help people with cardiac sarcoidosis, a condition where inflammation affects the heart. You may join if you have active inflammation on a PET scan despite standard treatments.
Baltimore, MarylandAges 18–80 - NCT07663292Recruiting
Exercise program to improve walking after stroke
This study tests whether a 12-week exercise program can help people who have had a stroke walk better. It focuses on those with a slower walking speed and uses brain scans to see if exercise can trigger positive changes in the brain.
Atlanta, GeorgiaAges 18–80 - NCT07649681Recruiting
