Interventions to make primary care diagnoses faster and safer
This trial tests a set of practice changes in primary care to improve diagnostic safety (making sure the right diagnosis is found) and efficiency (reducing time and delays). It may help patients who have certain lab results suggesting kidney function concerns and low hemoglobin (low blood level).
Houston, TexasAges 18 years+ - NCT05554692Enrolling by invitation
Study how aging and cochlear implants affect speech timing
This study looks at how the brain processes the timing of sounds and speech in people with cochlear implants and in people with typical hearing. It may help researchers understand what changes with age and how implant hearing works in the real world.
College Park, MarylandAges 18–85 - NCT05448326Recruiting
Revisiting test results for children and adults without a diagnosis
This study re-checks earlier genetic testing for people who still do not have a diagnosis for a developmental or physical difference. It may offer new genetic testing (like genome sequencing) using new or stored samples to help find a cause when the first results were unclear or negative.
DijonAges Any age - NCT05419895Recruiting
Early autism screening follow-up after a high-risk test score
This study looks at an “early diagnostic response” approach for toddlers who screen high-risk for autism. It aims to help families get timely follow-up and evaluation based on screening results.
Atlanta, GeorgiaAges 1.3 years–3 years - NCT04666402Recruiting
Testing better ways to diagnose early liver disease
This study looks at integrated diagnostic tests to find early liver problems sooner. It may help you (if referred to the community liver clinic) get more timely information about what’s going on.
Manchester, Greater ManchesterAges 18 years+ - NCT03676647Recruiting
Test DNA methylation from thyroid FNA samples to diagnose cancer
This study looks at a molecular test (DNA methylation pattern) using samples taken during fine-needle aspiration (FNA) of thyroid nodules. It aims to help identify which thyroid nodules that looked “unclear” after the first test may be cancer.
Duarte, CaliforniaAges 19 years+ - NCT07875582Recruiting
Blood test for better pancreatic cancer diagnosis
This study looks for proteins in the blood that could help doctors tell the difference between pancreatic cancer and non-cancerous pancreatic conditions, such as chronic pancreatitis or benign cysts. By participating, you could help improve early and accurate diagnosis, which may lead to better outcomes for future patients.
IașiAges 18 years+ - NCT07876882Recruiting
Comparing two bone scans for osteoporosis diagnosis
This study compares a newer, no-radiation bone scan (REMS) with the standard DXA scan to see if it's just as good at diagnosing osteoporosis and predicting fractures. If you're already getting a DXA scan, you might be able to participate and help improve bone health testing.
Easton, MarylandAges 30–90 - NCT07526545Recruiting
Urine test and MRI for early prostate cancer detection
This study tests a new urine test combined with an MRI to find prostate cancer early. It may help avoid unnecessary biopsies.
Ann Arbor, MichiganAges 50–75 - NCT06113861Recruiting
Better TB testing for kids in Bolivia
This trial tests new ways to diagnose tuberculosis (TB) in children with breathing problems. It aims to make TB detection faster and more accurate for kids who might have the infection.
Santa CruzAges 2 months–14 years - NCT06422806RecruitingPhase 3
Immunotherapy plus chemo for aggressive sarcoma
This trial compares a combination of immunotherapy (pembrolizumab) plus chemotherapy (doxorubicin) versus chemotherapy alone for people with aggressive, poorly differentiated sarcomas that have spread or cannot be removed. The goal is to see if adding immunotherapy helps shrink tumors or slow their growth better than chemotherapy alone.
Phoenix, ArizonaAges 18 years+ - NCT07027826Recruiting
String test for eosinophilic esophagitis in African patients
This study tests a new, less invasive way (the Esophageal String Test) to look for signs of eosinophilic esophagitis—an allergic condition that can make swallowing painful or difficult. It is for people of African descent who have trouble swallowing and are already having an endoscopy.
Bethesda, MarylandAges 18–65 - NCT03681964Recruiting
Check tests for suspected Sjögren’s syndrome
This study follows people who have signs that might mean Sjögren’s syndrome and looks at how well a standardized work-up identifies the condition. It may help doctors confirm the diagnosis earlier and more consistently.
BrestAges 18 years+ - NCT03853447Recruiting
Study of inflammation changes from pancreas flare to chronic disease
This trial studies how “inflammation” in the pancreas changes over time—going from a first or repeated attack to long-term (chronic) pancreatitis. It may help doctors understand what drives progression and identify people at higher risk for chronic disease.
Hvidovre, Capital Region DenmarkAges 18–70 - NCT01301885Recruiting
Tests new diagnosis and treatments for endometriosis
This trial studies people who definitely have endometriosis (confirmed by surgery and tissue testing) and compares them with people whose endometriosis was ruled out during laparoscopy. It aims to improve how endometriosis is diagnosed and to explore new treatment approaches.
HelsinkiAges 19–48 - NCT03717792Recruiting
Check how doctors follow up vascular liver disease
This study focuses on people who have vascular liver disease and aims to evaluate follow-up care and non-invasive ways to assess it. It may help improve how safely and accurately doctors monitor your liver without invasive procedures.
BonnAges 18–100 - NCT04917705Recruiting
Blood and tissue tests to find markers in muscle and skin disease
This study looks for blood and tissue “biomarkers” (measurable clues in samples) to help diagnose and predict outcomes in inflammatory muscle diseases and systemic sclerosis (a skin/organ condition). If you’re being evaluated for myopathy or early scleroderma, it may help doctors sort out the cause and follow your health more closely.
Strasbourg, Bas-RhinAges 18 years+ - NCT04804683Recruiting
FMD and SCAD registry study in Europe and beyond
This trial is a registry, meaning it collects detailed medical information to better understand fibromuscular dysplasia (FMD) and a specific type of heart-vessel dissection (SCAD) linked to FMD. It may help researchers learn who is at risk and guide better care in the future.
BrusselsAges Any age - NCT03746210Recruiting
Testing a painless scan to study liver spots in cirrhosis
This trial studies “focal liver lesions,” meaning specific spots in the liver, using a non-invasive (no surgery or biopsy) approach. It may help doctors better understand what these spots are in people who have cirrhosis.
