San Diego, CaliforniaAges 7–17 - NCT05504941Recruiting
Testing a treatment target map in sudden brain bleeding
This study looks at a special scan (DSA, done with contrast dye) to find a likely “target” that doctors can use when treating sudden brain bleeding. It’s meant to help doctors better understand where treatment may be needed soon after symptoms start.
BaselAges 18 years+ - NCT05512403RecruitingPhase 3
Test of FDOPA PET scan to evaluate a brain tumor
This study checks how well an FDOPA PET scan can identify and describe a specific type of brain tumor at the beginning. Results may help doctors decide on the best next steps for diagnosis and treatment planning.
Vandœuvre-lès-NancyAges 18–75 - NCT05530759Recruiting
Testing blood and tumor samples for diagnostic cancer markers
This study looks at blood and tumor tissue to find signs (markers) that can help diagnose or better understand metastatic cancer. You may be able to join if you’re getting surgery or a biopsy to remove a tumor and there’s a safe way to collect samples.
Rochester, MinnesotaAges 18 years+ - NCT05535634Recruiting
Sound-based hearing check for young Finnish-speaking children
This trial studies a sound-based hearing test to help check hearing in young children. It may be useful if your child is being evaluated for hearing but has no prior inner-ear hearing damage.
TurkuAges 3–10 - NCT05547607Recruiting
Study of heart valve infection signs on heart scans
This study looks at clinical symptoms and test findings to better understand heart valve infection (endocarditis) in adults. It may help doctors recognize the condition sooner and interpret echocardiography results more accurately.
Cona, FerraraAges 18 years+ - NCT05554224Recruiting
Personalized treatment based on obesity-related fatty liver tests
This study uses multiple types of health data (“multi-omics”) to help choose a personalized treatment plan for people with obesity-related fatty liver disease. It may help match treatment to your biology to improve outcomes.
Reus, TarragonaAges 18 years+ - NCT05565885Recruiting
Blood test study to find markers in adult vasculitis
This study looks for blood test markers that may help diagnose vasculitis and predict how it may go. You may be offered additional blood sampling if you have certain active vasculitis conditions.
ToursAges 16 years+ - NCT05568966Recruiting
Blood sample collection for new diagnostic tests
This study collects small blood samples to help test and improve new diagnostic devices. You may be eligible if you’re an adult with certain symptoms that match one of several health “groups,” and if you can consent and read English.
Airdrie, ScotlandAges 18 years+ - NCT05576974RecruitingPhase 2
Test a dye used during surgery to find head and neck cancer
This trial tests whether a single dose of an imaging dye (given during surgery) can help doctors find the unknown origin of head and neck cancer and check safety. It may help guide surgery and biopsies when the primary cancer location hasn’t been identified.
Dallas, TexasAges 18–99 - NCT05688176Recruiting
Testing blood RNA markers for esophagus cancer and Barrett’s
This study looks for helpful “RNA markers” found in blood to improve diagnosis in people with Barrett’s esophagus or esophageal cancer. It may help doctors spot disease more reliably, but it requires specific health and treatment conditions and a planned biopsy blood sample process.
Ghent, Oost-VlaanderenAges 18 years+ - NCT05698901Recruiting
Testing heart blood tests and scans to monitor Fabry disease
This study checks whether certain heart-related blood tests and heart scans can help monitor people with Fabry disease. It may be useful for both people who have never received enzyme replacement therapy and those who have.
TaipeiAges 18 years+ - NCT05703126Recruiting
Blood vessel and heart strength tests in AML patients
This study looks at how well your blood vessels and heart pumping ability work in people with acute myeloid leukemia (AML) receiving certain chemotherapy. It may help doctors better understand heart risk during treatment and tailor monitoring to you.
