Test EGb 761 for mild memory loss with brain blood vessel disease
This trial studies EGb 761 to see if it can improve symptoms in people with mild cognitive impairment (early memory/thinking changes) who also have signs of brain blood vessel disease. It may help by targeting the brain changes seen on scans.
SingaporeAges 45–85 - NCT04527445Recruiting
Test to use less X-ray during sacral nerve lead placement
This trial studies whether doctors can place a sacral neuromodulation lead using fewer X-rays. If you’re getting this procedure for overactive bladder, it may help reduce radiation exposure while still guiding correct lead placement.
Loma Linda, CaliforniaAges 18–89 - NCT04528355Recruiting
Study of hospital data after stem cell transplant for non-cancer illness
This study collects medical information from people with certain non-cancer conditions who receive a stem cell transplant. It may help doctors better understand transplant outcomes and care, since the study focuses on data collection rather than adding new treatment.
Pittsburgh, PennsylvaniaAges 2 months–60 years - NCT04532424Recruiting
Brain stimulation for repetitive behaviors in autism
This trial tests whether transcranial magnetic stimulation (a non-surgical treatment using magnets on the scalp) can reduce restricted and repetitive behaviors seen in autism. It’s designed for people with autism who have high levels of certain repetitive behaviors, like insistence on sameness or unusual interests.
Stanford, CaliforniaAges 12–45 - NCT04538937Recruiting
Study of high eosinophils causing lung/airway damage
This registry study looks at adults with high eosinophils (a type of immune cell) that are believed to be causing damage in the airways or lungs. It aims to better identify these eosinophils and understand what is going on so future treatments can improve.
InnsbruckAges 18 years+ - NCT04545424RecruitingPhase 2
Testing cooling treatment for severe lung failure in ICU patients
This trial tests whether therapeutic cooling (hypothermia) can improve outcomes in people with ARDS, a serious lung condition causing breathing failure. It may help by reducing harmful inflammation and lung injury, but eligibility is time-sensitive and requires ICU monitoring.
Los Angeles, CaliforniaAges 18–85 - NCT04558736RecruitingPhase 2
Haploidentical transplant for severe aplastic anemia in children
This trial tests a “half-matched” stem cell transplant for children and teens with severe aplastic anemia when a fully matched donor isn’t available. It may help rebuild blood-making cells after prior treatments did not work well enough.
Memphis, TennesseeAges Up to 21 years - NCT04561557RecruitingEarly Phase 1
Cell therapy for relapsing nervous system autoimmune diseases
This early-phase trial tests CT103A “CAR-T” cell therapy to treat certain relapsing or treatment-resistant autoimmune diseases that affect the nervous system. It aims to see whether the cells are safe and may help reduce disease activity when standard treatments haven’t controlled symptoms.
Wuhan, HubeiAges 18–75 - NCT04572503Recruiting
Surgery for mild to moderate sleep apnea not helped by CPAP
This trial looks at a modified palate surgery to treat mild to moderate obstructive sleep apnea in people whose CPAP machine isn’t working for them. It may help if your sleep apnea is caused by the tissue behind the soft palate collapsing rather than other airway areas.
Banhā, Qalyubia GovernorateAges 18 years+ - NCT04581512RecruitingPhase 1/Phase 2
Safety study of EP0042 for certain AML patients
This Phase 1/2 study tests how safe and tolerable EP0042 is, and looks at patients with a specific type of AML that has come back or did not respond to prior treatment. You may be considered if your AML diagnosis is confirmed and your lab tests, overall health, and medication history fit the study rules.
