Lahore, Punjab ProvinceAges 40–75 - NCT07244952Recruiting
Vojta therapy for posture and trunk control after stroke
This trial tests a type of movement therapy called Vojta Therapy to see if it helps improve posture and trunk control after a stroke. It is for people who had their first stroke within the past 3 months and have significant weakness on one side of the body.
LahoreAges 45–65 - NCT07240441Recruiting
Comparing heart ablation methods for post-heart attack VT
This trial tests two ways to do a heart procedure (ablation) in people who have had a heart attack and now have dangerous fast heart rhythms. It compares the usual method (inside the heart only) with a method that also works on the outer surface of the heart. The goal is to see which works better to stop these rhythms.
Warsaw, Masovian VoivodeshipAges 18–85 - NCT07246135Recruiting
Leadless Pacemaker Registry: Patient Outcomes
This registry tracks patients who have received a leadless pacemaker at the University Hospital of St. Pölten. It helps doctors learn how well these small, wire-free pacemakers work over time.
Sankt Pölten, Lower AustriaAges 18 years+ - NCT07242391Recruiting
Menopausal hormone therapy and heart function study
This study looks at how menopausal hormone therapy might affect the heart's pumping ability. It may help women who are naturally entering menopause understand if hormone therapy can protect their heart health.
Rochester, MinnesotaAges 45–60 - NCT07244614Recruiting
Study of ustekinumab or apremilast for Behçet's disease symptoms
This study tests if ustekinumab or apremilast can help control Behçet's disease symptoms like mouth and genital ulcers, skin sores, and joint pain. It may be an option if standard treatments haven't worked well.
BordeauxAges 18 years+ - NCT07240454Recruiting
Should you keep taking aspirin for a chronic brain bleed?
This trial looks at whether people with a chronic subdural hematoma (a slow bleed on the brain) who are not having surgery should keep taking aspirin or stop it. It aims to find out which approach is safer and helps the hematoma heal better.
BeijingAges 18 years+ - NCT07244809Recruiting
Study on stress history and blood vessel health in young adults
This study tests whether early-life stress affects blood vessel function in young adults by looking at a type of cell stress called oxidative stress. It involves measuring how well your blood vessels work and may help understand why some people have higher heart risks.
Iowa City, IowaAges 18–29 - NCT07247669Recruiting
AI phone triage for emergencies
This study tests if artificial intelligence can help identify time-sensitive emergencies like stroke, heart attack, or trouble breathing from recorded phone calls. The goal is to make emergency response faster and more accurate.
Málaga, MálagaAges Any age - NCT07249528Recruiting
Using voice recordings to monitor side effects during CAR T-cell therapy
This study tests if daily voice recordings on a smartphone can help detect side effects early in people receiving CAR T-cell therapy for non-Hodgkin lymphoma or multiple myeloma. You will make short voice recordings twice a day and have daily neurological checks.
Basking Ridge, New JerseyAges 18 years+ - NCT07249073RecruitingEarly Phase 1
Dual-target CAR-T for relapsed/refractory myeloma
This trial tests a new CAR-T cell therapy that targets two proteins (BCMA and CD19) on myeloma cells. It may help patients whose myeloma has come back or stopped responding to previous treatments.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT07246473Recruiting
