Beijing, Beijing MunicipalityAges 55–75 - NCT05031897RecruitingPhase 2
Haplo transplant with reduced donor mismatch and radiation
This trial tests a special bone marrow/stem cell transplant approach using a partially matched family donor, along with conditioning treatment that involves radiation. It aims to help treat certain blood cancers by replacing damaged blood-forming cells with new ones from the donor.
Philadephia, PennsylvaniaAges 18 years+ - NCT05033678Recruiting
Teledermoscopy and AI help review your skin spot images
This study tests a way for doctors to send clear images of your skin spot to be reviewed remotely using teledermoscopy (digital images of the skin). It may help speed up specialist input and improve how skin spots are assessed.
LundAges 15 years+ - NCT05043012Recruiting
Testing a special MRI scan for prostate cancer diagnosis
This study checks how well a new prostate MRI scan (using a flexible coil and multiple MRI types) can correctly identify prostate cancer and help with treatment planning. You may be able to help doctors improve prostate imaging before you have surgery.
Houston, TexasAges 18 years+ - NCT05056740Recruiting
Inflammatory markers for CNS autoimmune disease diagnosis
This trial studies whether certain inflammatory biomarkers in blood and spinal fluid can help diagnose autoimmune diseases affecting the brain and spinal cord. It may help people who are undergoing testing for white matter lesions.
NiceAges Any age - NCT05079711Recruiting
Compare a vaginal yeast test for women with symptoms
This study compares how well a new vaginal yeast (Candida) test matches a standard yeast culture test. It may help clinicians choose the most accurate, convenient way to tell whether vaginal symptoms are caused by yeast.
Fort Bragg, North CarolinaAges 18 years+ - NCT05146726Recruiting
Finding the best care for low blood before planned surgery
This study looks at how to detect and treat pre-surgery anemia (low hemoglobin/low blood level) in people having planned operations where blood transfusion is likely. Some participants may also use a machine that collects and returns their own blood during surgery to reduce the need for donor blood.
BerlinAges 18 years+ - NCT05149638Recruiting
Checking updated cortisol lab values for adrenal insufficiency
This study tests whether updated cortisol test numbers better identify adrenal insufficiency, a hormone condition where your body doesn’t make enough stress hormone. It may help doctors confirm the diagnosis and choose safer next steps for treatment.
The Bronx, New YorkAges 18 years+ - NCT05160337Recruiting
Testing how well blood test markers stay stable in healthy people
This study checks whether certain lab “biomarker” results from blood samples remain accurate over time. The goal is to validate diagnostic tests by testing samples from healthy adults under controlled conditions.
HuningueAges 18–85 - NCT05174247Recruiting
Using FFRct to guide tests for stable chest pain
This study checks whether adding FFRct analysis (a special computer-based estimate of blood flow from a CT scan) improves the diagnostic pathway for people with stable chest pain. It may help doctors decide what to do next by clarifying how much a narrowed heart artery is truly limiting blood flow.
Rotterdam, South HollandAges 18 years+ - NCT05217940Recruiting
Screening women with prior HPV for anal abnormalities
This study looks for early anal cell changes in women who have had high-grade HPV-related problems in the cervix, vagina, or vulva. It may help find concerning changes sooner, using a structured screening exam.
