BonnAges 18–85 - NCT07334834Recruiting
Better cholesterol management for people with artery disease
This study tests a team-based approach to help people with artery disease (like heart attacks or leg blockages) get their cholesterol to a healthier level. If your LDL is above 70, you may benefit from extra support to manage your medications.
Aurora, ColoradoAges 18 years+ - NCT07334977RecruitingPhase 2
Brain and spinal cord stimulation after stroke or injury
This trial tests whether stimulating the brain and spinal cord together can help people recovering from stroke or spinal cord injury. It also includes a healthy control group for comparison.
BordeauxAges 18 years+ - NCT07335900Recruiting
Studying heart healing after TAVI with FAPI-PET scan
This study uses a special type of PET scan (FAPI-PET) to see how the heart heals after a less invasive valve replacement procedure called TAVI. It aims to help doctors better understand the changes in heart tissue after treatment for aortic stenosis.
ShanghaiAges 18 years+ - NCT07336225Recruiting
CMR Study for Heart Device Patients
This study looks at people who already had a heart MRI before getting a pacemaker, defibrillator, or other heart device. It aims to learn how MRI results might predict long-term outcomes for these patients.
BeijingAges 18 years+ - NCT07336394Recruiting
Study on rare heart muscle diseases using advanced MRI
This study uses a special heart MRI to better diagnose and understand rare heart muscle diseases. It may help doctors predict risks and make more accurate treatment decisions.
BeijingAges Any age - NCT07336823RecruitingEarly Phase 1
JY232 CAR-T cell therapy for relapsed multiple myeloma
This trial tests an investigational CAR-T cell therapy called JY232 for people with multiple myeloma that has returned or not responded to at least two prior treatments. The therapy targets a protein called BCMA on myeloma cells to help your immune system fight the cancer.
Foshan, GuangdongAges 18–75 - NCT07338175RecruitingPhase 3
Testing minocycline for brain bleeding recovery
This trial tests if the antibiotic minocycline can help people recover after a spontaneous brain bleed (intracerebral hemorrhage). It is for patients who have a moderate-sized bleed and are within 48 hours of symptoms starting.

BCMA gene therapy for recurring autoimmune diseases
This early-phase trial tests a new gene therapy (BCMA LV injection) for people with autoimmune diseases like lupus, IgG4-related disease, scleroderma, myositis, or vasculitis that keep coming back or don't respond to standard treatments. The goal is to see if targeting a specific immune cell protein (BCMA) can help control the disease.
Wuhan, HubeiAges 18–65 - NCT07339787Recruiting
How well do ER doctors diagnose TIAs?
This study looks at how well doctors in the emergency room diagnose transient ischemic attacks (TIAs) — temporary, minor strokes that quickly resolve. It aims to improve future care by reviewing records of people who had these symptoms.
StrasbourgAges 18 years+ - NCT07339813Recruiting
