Recruiting studies
- NCT06419101Recruiting
Finding early signs of memory loss in China
This trial looks for new ways to diagnose memory and thinking problems earlier. It involves a memory test, brain scan, and blood draw to find markers that could help identify cognitive disorders.

TB detection test for new pleural fluid buildup
This study tests a new blood or fluid test (cell-free DNA) to find tuberculosis (TB) in people who have new fluid buildup around their lungs. If you are 18 or older and scheduled for a procedure to drain that fluid, you may be able to join.
Shatin, Hong KongAges 18 years+ - NCT06440850RecruitingPhase 2
Targeted therapy for high-risk BRAF-mutated thyroid cancer
This trial tests two targeted drugs, vemurafenib and cobimetinib, for people with high-risk thyroid cancer that has a specific BRAF V600E mutation. The goal is to see if this combination can help prevent the cancer from coming back after surgery or other initial treatments.
Duarte, CaliforniaAges 18 years+ - NCT06445088Recruiting
Testing a new EBV DNA test for nasopharyngeal cancer
This trial is testing a new way to diagnose nasopharyngeal cancer using a special test that looks at a change in the EBV virus DNA. It is for people who may have symptoms of this cancer or have tested positive for EBV, but have not yet been treated.

Gemcitabine and leflunomide for advanced pancreatic cancer
This trial tests if adding leflunomide (a drug used for arthritis) to standard chemotherapy (gemcitabine) can help people with advanced pancreatic cancer that cannot be removed by surgery. The goal is to see if the combination works better than gemcitabine alone.
Duarte, CaliforniaAges 18 years+ - NCT06463392Recruiting
Deep learning tool to diagnose post-radiation nasopharyngeal changes
This trial tests a new computer-based tool (deep learning) to help diagnose a condition called sbORN (suspected benign or recurrent nasopharyngeal carcinoma) after radiation therapy. It aims to see if the tool can accurately tell if a suspicious spot is a recurrence or something harmless.
Guangzhou, GuangdongAges 18 years+ - NCT06466018Recruiting
Eye disorder biomarkers study for European adults
This study looks for new ways to diagnose and track eye disorders using imaging and genetic tests. It may help find better treatments for conditions linked to blood vessel and nerve problems in the eye.
ParisAges 18 years+ - NCT06467383Recruiting
Study of lung cancer care after surgery or radiation
This study is looking back at the medical records of people with early-stage non-small cell lung cancer who had surgery or radiation therapy between 2018 and 2019. The goal is to understand how patients were diagnosed and treated, which may help improve care for others in the future.
San Giovanni Rotondo, FGAges 18 years+ - NCT06474806RecruitingPhase 2
PET scan for untreated prostate cancer
This trial tests a new type of PET scan that looks for a protein called uPAR on prostate cancer cells. It might help doctors see your cancer more clearly without needing surgery or treatment first.
Herlev, CopenhagenAges 18 years+ - NCT06475560Recruiting
Camera capsule endoscopy for colorectal disease diagnosis
This trial tests a camera pill (capsule endoscopy) as an alternative to a regular colonoscopy for people with colon or rectum symptoms. It's a simpler way to look inside your large intestine without a tube.
Odense CAges 18 years+ - NCT06482463Recruiting
D-lactate test for meningitis in patients with a brain drain
This study checks if a substance called D-lactate in the fluid around your brain can help diagnose meningitis that develops in the hospital after a brain drain (ventriculostomy). It aims to improve diagnosis.
ToulouseAges 18 years+ - NCT07693816Recruiting
Finding stroke caused by small artery disease
This study looks at whether your stroke was caused by branch atheromatous disease (BAD), a type of small artery blockage. Knowing this may help choose the best treatment and prevention plan.
BeijingAges 18–80 - NCT07691697Recruiting
PSMA PET-guided radiation for slowing prostate cancer growth
This trial uses a special scan called PSMA PET to find and treat a small number of cancer spots that are growing while you are on standard treatment. The goal is to give precise radiation to those spots to help keep the rest of the cancer under control.
Zamość, Lublin VoivodeshipAges 18 years+ - NCT06490029Recruiting
Hearing loss from cancer treatment: a diagnosis study
This study looks at hearing problems caused by cancer treatments that can damage the ears or nervous system. It aims to better understand and diagnose these side effects to help patients.
ParisAges 18 years+ - NCT06494228Recruiting
Comparing MRI scans for optic neuritis
This study compares three types of brain MRI scans (3D FLAIR, DIR, and PSIR) to see which is best at detecting optic neuritis (inflammation of the optic nerve). It looks at scans from patients with multiple sclerosis or NMO spectrum disorder to improve diagnosis.
Strasbourg, Les Hôpitaux Universitaires de StrasbourgAges 18 years+ - NCT06501599Recruiting
AI system for spotting COVID-19 lung changes on CT scans
This trial tests an artificial intelligence tool that helps doctors identify lung changes caused by viral pneumonia, like COVID-19, on CT scans. It may lead to faster and more accurate diagnosis for patients.
MoscowAges 18 years+ - NCT06510894Recruiting
Testing a drug to improve heart imaging
This study tests if a drug can help suppress sugar uptake in the heart for clearer imaging. It may help researchers understand how to better see heart problems.
Philadelphia, PennsylvaniaAges Any age - NCT06513000Recruiting
Dry eye changes after cataract surgery
This study measures how dry eyes get after cataract surgery. It may help patients know what to expect after their operation.
SohagAges 45 years+ - NCT06515821Recruiting

SofiaAges 18 years+ - NCT06525571RecruitingPhase 3
Blue light surgery for high-risk bladder cancer
This trial tests if using blue light during surgery helps remove all cancer in people with high-risk non-muscle invasive bladder cancer. It may lower the chance of the cancer coming back.

Common questions
- Are there clinical trials for diagnostic?
- Yes. Clin2 currently lists 677 recruiting diagnostic studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a diagnostic trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a diagnostic trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
