Testing a new approach for heart failure with weak pump
This study tests a new device or procedure to help people with heart failure and a weak heart pump. If you have a low ejection fraction and are on standard medications, you may be able to join.

Testing a treatment for heart failure symptoms with normal pumping ability
This study is looking at a new treatment for people with heart failure where the heart’s pumping strength is not reduced much (HFpEF or HFmrEF), but pressure inside the heart is high during exercise. It may help relieve symptoms in people who still feel unwell during normal activity despite stable standard treatment.
Phoenix, ArizonaAges 40 years+ - NCT07766135Recruiting
Liver and blood clotting in heart amyloidosis
This study looks at how the liver and blood clotting are affected in people with a type of heart disease called transthyretin amyloidosis. It may help doctors better understand and manage this condition.
Messina, SicilyAges 18 years+ - NCT07764588Recruiting
Immune cell study after a heart attack
This study looks at how immune cells change in the first few hours after a severe heart attack (STEMI) and how that relates to early scar healing. It may help doctors understand why some patients heal better than others.
ShanghaiAges 18–80 - NCT07256704Recruiting
Hypnosis and attention for neurological conditions
This study looks at whether hypnosis can help improve attention in people with conditions like stroke, traumatic brain injury, or multiple sclerosis. It may help if you have trouble concentrating or focusing.
LucerneAges 18 years+ - NCT07764900Recruiting
Embolization for varicocele
This study tests a minimally invasive procedure to treat varicocele, which is an enlargement of veins in the scrotum that can cause pain or affect fertility. The procedure blocks the abnormal veins to improve symptoms and potentially fertility.
Sohag, Sohag GovernorateAges 16–60 - NCT06166654RecruitingPhase 4
Better water pill therapy for acute heart failure
This trial tests different water pill (diuretic) strategies for people hospitalized with acute heart failure and too much fluid. It is designed for patients who may not respond well to standard water pills, to find a more effective way to relieve symptoms.
Hvidovre, Capital Region of DenmarkAges 18 years+ - NCT06870812Recruiting
Quick removal of brain bleed clot study
This trial tests a rapid procedure to remove a blood clot in the brain after a specific type of stroke. It might help people with a moderate-sized bleed in the front part of the brain if treatment can start within 24 hours.
Birmingham, AlabamaAges 18–70 - NCT07052903RecruitingPhase 3
RNA therapy for ATTR amyloidosis with heart involvement
This trial tests an experimental RNA therapy (nucresiran) for people with transthyretin amyloidosis that causes heart problems (cardiomyopathy). It aims to lower the abnormal protein buildup to help heart function.
La Jolla, CaliforniaAges 18–85 - NCT06400186Recruiting
Walking training to improve balance after stroke
This trial tests a new walking training method designed to help you improve your balance after a stroke. It's for people who have had a stroke more than 6 months ago and can walk a short distance, with or without a cane or simple ankle brace.
Chicago, IllinoisAges 18–80 - NCT04104464Recruiting
Patient reports after treatment for vascular malformations
This study looks at how patients feel after a procedure used to treat vascular malformations (abnormal blood vessel growth). You may be asked to complete questionnaires about symptoms and quality of life before and after treatment.
Baltimore, MarylandAges birth–100 years - NCT05020236RecruitingPhase 3
Elranatamab with daratumumab for previously treated myeloma
This trial studies elranatamab (alone and combined with daratumumab) in people with multiple myeloma who have already received other treatments, including lenalidomide. It aims to see how well these medicines control the cancer and what side effects people experience.
Clovis, CaliforniaAges 18 years+ - NCT07098572Recruiting
Comparing two types of electrical stimulation for arm recovery after stroke
This study tests whether a four-channel electrical stimulation device works better than a standard one-channel device for improving arm and hand movement in people who recently had a stroke. The goal is to help with recovery of daily activities.
Hermagor, CarinthiaAges 18–99 - NCT07409246RecruitingPhase 1
Study of ABBV-438 for multiple myeloma patients
This trial tests a new intravenous treatment, ABBV-438, for adults with multiple myeloma that has returned or not responded to prior therapies. It aims to see if the drug is safe, tolerable, and how it moves through the body.
Duarte, CaliforniaAges 18 years+ - NCT04058639Recruiting
Custom felt dressing trial for diabetic foot ulcers
This trial tests whether a special padded (felt) dressing can help heal diabetic foot ulcers with nerve-related injury. If you have a foot wound caused by diabetic nerve problems, the study may offer a shorter treatment time.
MoldeAges 45–80 - NCT05145478Recruiting
Real-world outcomes after Shockwave treatment for blocked leg artery
This study follows what happens in real life after using Shockwave’s device (intravascular lithotripsy) to treat a hard, calcified blockage in the common femoral artery, then completing standard treatment. It may help doctors understand which patients benefit and what results to expect.
New Haven, ConnecticutAges 18 years+ - NCT06374498Enrolling by invitation
Looking inside heart arteries to improve stent placement
This study tests a new imaging technique to help doctors see inside your heart arteries during a stent procedure. It may help guide treatment and improve outcomes for people with heart disease.
Boston, MassachusettsAges 18 years+ - NCT07413965Recruiting
Transcatheter vs surgical valve replacement for severe bicuspid aortic stenosis
This trial compares two ways to replace a narrowed heart valve in people with a bicuspid aortic valve. If you're 50 or older and need a new valve, this study can help figure out which approach works best.
Los Angeles, CaliforniaAges 50 years+ - NCT03630211RecruitingPhase 2
Study of stem cell transplant for systemic sclerosis in youth
This Phase 2 study tests whether an “autologous” stem cell transplant—using your own stem cells—can reduce systemic sclerosis disease activity. It is mainly for children, teens, and young adults whose disease did not improve despite standard medicines.
Pittsburgh, PennsylvaniaAges 8–60 - NCT07555938RecruitingPhase 3
New drug combination for previously treated multiple myeloma
This trial tests whether a new drug called cevostamab, combined with two existing myeloma drugs (pomalidomide and dexamethasone), works better than standard treatment for people whose myeloma has returned or stopped responding to prior therapy. You would receive this combination to see if it helps control your disease.
Duarte, CaliforniaAges 18 years+ - NCT07349797Recruiting

Treatment for stroke caused by blocked brain and neck arteries
This trial studies a procedure that opens blocked blood vessels in and behind the brain during a stroke, sometimes after standard clot-thinning medicine. It may help people who have brain tissue that can still be saved and a major blockage in both the neck and brain arteries.
Montreal, QuebecAges 18 years+ - NCT07392450RecruitingPhase 2
Study of TAK-755 for adults with acute ischemic stroke
This trial tests if TAK-755 can help people who have had a moderate to severe stroke within the last 24 hours. It aims to see if the drug can improve recovery by protecting brain tissue that is still salvageable.
Scottsdale, ArizonaAges 18 years+ - NCT06681896Recruiting
Exercise rehabilitation for heart microvessel disease
This trial tests a supervised exercise program for people with chest pain caused by tiny heart blood vessel problems (microvascular dysfunction). It aims to see if exercise can improve symptoms and heart function.
