Salt Lake City, UtahAges 18 years+ - NCT02748941Recruiting
Imaging study of narrowed neck arteries after stroke
This study looks at new imaging markers in people with significant narrowing of the carotid artery (the main artery in the neck). It compares people who recently had a stroke from that artery with people who have no recent stroke, to better understand stroke risk and artery disease.
BronAges 18 years+ - NCT02897908Recruiting
Noninvasive scan to check liver fat and scarring
This study tests a noninvasive FibroScan machine to help measure liver fat and possible liver scarring using information collected in a database. It may help researchers improve how liver problems like fat buildup and scarring are identified and tracked.
Buffalo, New YorkAges 18 years+ - NCT02994160Recruiting
DEFT hand control test for people with arm amputations
This study tests a special implanted system meant to help control a hand using nerve signals. It is for adult arm/hand amputees and may help improve hand/arm control and reduce pain impacts.
Dallas, TexasAges 18–95 - NCT02991625Enrolling by invitation
Brain scan study to find markers for chronic back pain
This study uses brain imaging (MRI scans) to look for “biomarkers” (measurable signs) that may relate to chronic low back pain. It compares people with long-lasting back pain to healthy volunteers to understand what brain patterns are linked to pain.
Halifax, Nova ScotiaAges 18–75 - NCT02639299Recruiting
Screening healthy adults for malaria vaccines and drug studies
This study screens healthy adults to see who can join future malaria vaccine or investigational malaria drug studies, including a controlled malaria exposure. It may help researchers test safer vaccines/drugs, but participation requires good health and strict medical eligibility.
Bethesda, MarylandAges 18–50 - NCT02207894Recruiting
Survey of removing inhibitors in hemophilia A treatment
This study collects real-world information on how well a personalized clotting-factor plan helps people with hemophilia A get rid of inhibitors. It may help doctors refine treatment for patients who develop antibodies that block factor therapy.
Frankfurt am Main, HesseAges Any age - NCT02411773RecruitingPhase 1
Test a nerve-blocking medicine in kidney disease
This Phase 1 study tests whether a medicine that reduces nerve signals (“sympatholysis”) is safe and how it affects people with chronic kidney disease. It may help researchers understand new ways to protect the kidneys, but the main goal here is safety.
Decatur, GeorgiaAges 18–75 - NCT02497261Enrolling by invitation
Study factors that predict peanut allergy at age five
This study looks at which early test results and symptoms help predict whether a child will still have a peanut allergy by age 5. It may help families and doctors better understand who is at higher risk and plan next steps.
Ages 4–10 - NCT02413450Enrolling by invitation
Using patient DNA cells to study inherited heart rhythm risks
This study uses your blood or genetic information to make “iPS cells,” lab-grown cells that can help researchers study inherited heart rhythm problems like LQTS, Brugada syndrome, CPVT, or early repolarization syndrome. It may help improve understanding of why these rhythms happen and guide future treatments.
