This trial uses an artificial-intelligence tool to help detect pancreatic cancer earlier and track people at higher risk. You may be asked to complete questionnaires and have imaging tests like MRI or CT to see how well the approach works.
ShanghaiAges 50–75 - NCT04766866Recruiting
Check two blood markers to help prevent preeclampsia
This trial tests whether measuring two pregnancy blood markers (sFlt1 and PlGF) and planning delivery timing can help prevent preeclampsia as you reach term. It may help reduce risk for mother and baby by guiding when to deliver based on test results.
LiègeAges 18 years+ - NCT04767568Recruiting
Testing a blood test to guide colorectal cancer screening care
This study looks at whether a simple blood test can help guide the care of people being evaluated for colorectal cancer. It may support earlier or clearer decision-making alongside existing screening or colonoscopy results.
BesançonAges 18 years+ - NCT04852354Recruiting
Donate brain/spinal tumor tissue for drug testing
This study collects leftover brain or spinal tumor tissue during neurosurgery (or from autopsies) so researchers can test drugs and measure how they work. It may help future treatments by improving drug screening using real patient tissue.
New York, New YorkAges Any age - NCT04859530Recruiting
Smartphone AI test for cervical cancer screening
This study checks whether a smartphone-based AI tool can help screen for cervical cancer. You may be offered the AI-assisted screening during a clinic visit to see if it works well when visualizing the cervix.
Dschang, MenouaAges 30–49 - NCT04873258Recruiting
Test a non-invasive tool to screen for fat-related liver disease
This study looks at a new non-invasive screening method to predict metabolic dysfunction–associated steatotic liver disease (MASLD), a condition where fat builds up in the liver. The goal is to help identify people who may be at risk without needing invasive tests.
London, LondonAges 18–80 - NCT04901351Recruiting
Genetic testing for persistent high-risk HPV after treatment
This study uses a detailed DNA test to look for high-risk HPV in people with long-lasting (chronic) infection after treatment or with return of abnormal cells. It may help improve how clinicians monitor high-risk HPV and decide next steps.
ToulouseAges 18 years+ - NCT04910802RecruitingPhase 4
HPV vaccine with routine HPV screening for ages 22–26
This study looks at giving the HPV vaccine (Gardasil 9) to women while they go through Sweden’s routine HPV screening. It helps researchers understand how vaccine use alongside screening affects HPV infection and cervical cancer prevention.
StockholmAges 22–27 - NCT05142800Recruiting
Screening for Lymphedema in Breast Cancer Targeted Therapy
This study is looking at whether targeted therapy for breast cancer changes the risk of arm swelling (lymphedema). It is a screening trial that uses a machine to measure arm size and check for any swelling early on.
Boston, MassachusettsAges 18–80 - NCT04938804Recruiting
One-time lung cancer screening with a low-dose chest CT
This study tests whether a one-time, low-dose chest CT scan can help find lung cancer early in certain people. You may be invited because of your age and location, and because you have not had recent related testing or symptoms.
Guangzhou, GuangdongAges 40–74 - NCT04964310Recruiting
Testing genetic risk for acetaminophen-related liver injury
This study looks at whether certain genes can predict who is more likely to get liver injury after taking acetaminophen (also found in some cold/flu medicines). By comparing people who were affected with people who were not, it may help doctors identify higher-risk patients in the future.
Nanjing, JiangsuAges 14 years+ - NCT04967183Recruiting
Compare a stool blood test versus colonoscopy follow-up after precancer removal
This study compares two ways of checking for colorectal cancer risk after advanced polyps are removed. It may help determine whether a stool test can safely replace some colonoscopy surveillance for certain people.
OurenseAges 50–65 - NCT04990908Recruiting
Screening children in ICU for immune problems after severe infection
This study checks children in pediatric intensive care for possible “immune system problems” after a severe infection. The goal is to find primary immunodeficiencies early, which may change follow-up and treatment for the child’s immune health.
MontpellierAges 3 months–16 years - NCT05049889Recruiting
Diver screening to spot risk for lung fluid after diving
This study checks whether certain personal factors can predict who may get “immersion pulmonary edema,” a condition where fluid builds up in the lungs after water exposure and diving. If you’re a diver, your results may help tailor safety steps and reduce risk.
ToulonAges 18–60 - NCT05108896Recruiting
Testing breathing and swallowing recovery after ICU breathing support
This study looks at aspiration (food or liquid going “the wrong way” into the airway) in people who survived a serious ICU breathing problem. It may help doctors better support safe swallowing and breathing recovery after being on a breathing machine.
Stanford, CaliforniaAges 18 years+ - NCT05115474RecruitingPhase 2
