This trial tests whether giving a clot-dissolving medication directly into the brain's blood vessels during a standard procedure (mechanical thrombectomy) can improve outcomes for people with a stroke caused by a blockage in a medium-sized artery. It may be an option for patients who arrive at the hospital within 24 hours of symptom onset and have enough salvageable brain tissue.
Guangzhou, GuangdongAges 18 years+ - NCT07665632Recruiting
Polarized aerobic training for healthy adults aged 30-50
This study tests a type of aerobic exercise called 'polarized training' in healthy adults who are currently not active. It looks at how this training affects blood vessel health. If you are between 30 and 50, healthy, and not exercising regularly, you may be eligible.

New treatment for newly diagnosed transplant-ineligible myeloma
This Phase 3 study compares a three-drug combination (elranatamab, daratumumab, and lenalidomide) versus a standard three-drug treatment (daratumumab, bortezomib, lenalidomide, plus dexamethasone). It aims to see which plan works better for people newly diagnosed with multiple myeloma who cannot get a stem cell transplant.
Jupiter, FloridaAges 18 years+ - NCT06368648Recruiting
Study of a new forehead sensor for brain pressure monitoring
This study tests a new sensor that measures brain pressure from outside the head. It is for people who are already in the hospital getting their brain pressure and blood pressure monitored continuously.
Sacramento, CaliforniaAges 18 years+ - NCT07324772Recruiting
Exercise program to improve symptoms in atrial fibrillation and heart failure
