Cholesterol medicines after stent: combo pill vs single pill
This trial compares two cholesterol-lowering treatment plans after a heart procedure where new drug-eluting stents were placed: a combination of high-intensity statin plus ezetimibe versus high-intensity statin alone. It may help find which option lowers cholesterol more effectively and safely over the first year after the procedure.
SeoulAges 19 years+ - NCT05794880Recruiting
Immunotherapy lowering immune cells before transplant in children
This trial tests a special immune-cell “preparation” treatment (called T-cell and B-cell depletion) with adjusted anti-thymocyte globulin (ATG) dosing before a stem cell transplant. It aims to reduce immune-related transplant complications in people under 25 with certain blood cancers in a specific remission status.
Milwaukee, WisconsinAges birth–25 years - NCT05799378RecruitingPhase 3
Stopping hydroxychloroquine in older adults with stable lupus
This study looks at whether it is safe for people aged 55 and older with long-standing, stable lupus to stop taking hydroxychloroquine (a medicine that helps control lupus) without their disease flaring up. If you have been taking this medicine for at least 7 years and your lupus has been quiet for a while, you may be able to join.
Los Angeles, CaliforniaAges 55 years+ - NCT05800639Recruiting
Testing brain-wave patterns during pediatric anesthesia awakening
This study looks at brain-wave activity (measured with sensors) in young children during and after general anesthesia for planned eye surgery. It may help doctors understand why some children become very upset or confused as they wake up.
SeoulAges 2–8 - NCT05806801Recruiting
Study how weight loss changes the body with or without exercise
This study looks at how your metabolism (how your body uses energy and controls blood sugar/fats) changes during weight loss, comparing weight loss alone versus weight loss plus exercise. It may help researchers understand what body changes happen with different approaches and why.
