BeijingAges Any age - NCT03869814Recruiting
Blood test to study cancer signals without invasive procedures
This study looks at a non-invasive blood test to detect cancer-related “signal patterns” and see how well they match different types of cancer. It may help researchers learn better ways to find or understand cancer using less invasive testing.
San Diego, CaliforniaAges 21–80 - NCT04529629Recruiting
Tests and tracks treatment for adrenal hormone tumor diseases
This trial studies how adrenal hormone tumor diseases should be diagnosed, treated, and followed over time. It may help people get more precise care and better prediction of outcomes, but it has specific health and medication requirements.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04047784Enrolling by invitation
Using EBUS to help diagnose a blood clot in the lungs
This study looks at whether a procedure called EBUS (a camera passed through the airway) can help doctors diagnose an acute pulmonary embolism—a sudden blood clot in the lungs—in critically ill, intubated ICU patients. If you’re eligible, EBUS may be done during bronchoscopy as part of your usual care to help confirm or rule out the diagnosis.
Los Angeles, CaliforniaAges 18 years+ - NCT02060565Recruiting
Test noninvasive scans to diagnose chronic liver disease
This study looks at how well noninvasive tests (tests that don’t require surgery, like scans and blood-based measurements) can diagnose chronic liver disease in people with certain liver conditions. It may help doctors choose better, less invasive ways to identify the type and stage of liver problems.
PessacAges 18 years+ - NCT07670351Recruiting
Blended learning for nursing students' psychosocial care
This trial tests a blended learning program to help nursing students better understand and address patients' emotional and social needs. If you are a nursing student at the study institution, you can help evaluate this educational approach.

Treatment plan for children with brain ependymoma after surgery
This trial tests different follow-up treatments for children with brain ependymoma after their initial surgery. Which treatment you get depends on how much tumor is left (if any) and whether the child can safely receive radiation and chemotherapy.
GrazAges Up to 22 years - NCT05888987Recruiting
New test for severe corneal infection diagnosis
This study tests a new method for identifying bacteria causing severe corneal infections. It may help doctors choose the right treatment faster by improving how the infection is identified from corneal samples.
ReimsAges 18 years+ - NCT05427695RecruitingPhase 2
Probiotic rinse to treat chronic sinus inflammation
This Phase 2 study tests whether washing your sinuses with a probiotic solution can improve chronic sinusitis symptoms and inflammation. It’s for adults with chronic sinus symptoms that have flared, especially if you’ve had sinus surgery in the past.
Chicago, IllinoisAges 18 years+ - NCT02869516Recruiting
Acute leukemia patient database study
This study enrolls people who have been diagnosed with acute leukemia and collects health information in a database. It may help doctors better understand care outcomes and improve future treatment planning.
Marseille, Bouches-du RhôneAges 18 years+ - NCT07656181Recruiting
Standardizing quality criteria for liver ultrasound with contrast
This trial gathers expert doctors to create standard quality rules for liver ultrasound exams that use contrast dye. If you're a very experienced ultrasound doctor, your opinion could help shape future care.
Bern, Canton of BernAges Any age - NCT06245954Recruiting
Better diagnosis through lung sampling training
This trial studies whether standardizing the training for a lung biopsy procedure helps doctors better diagnose interstitial lung disease. You might be eligible if you have a suspected ILD diagnosis and your lung function and other health markers are within certain limits.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06429891Recruiting
Nuclear probe for early gastric cancer detection
This trial uses a special radioactive probe to find gastric cancer cells during imaging. It may help doctors see tumors more clearly and catch the disease earlier.
Beijing, Beijing MunicipalityAges 18–70 - NCT06420115Recruiting
Comparing needle sizes for prostate MRI-targeted biopsy
This study compares two different needle sizes used during a prostate biopsy to see which one finds cancer more accurately and causes fewer side effects. It is for people who have not been diagnosed with prostate cancer before and have a suspicious MRI finding.
Padua, ItalyAges 18 years+ - NCT07664488Recruiting
AI vs. Manual Analysis of Skull X-rays
This trial tests whether a computer program using artificial intelligence can measure skull and jaw landmarks from X-rays as accurately as a human expert. It may help improve future orthodontic care.
Pavia, ItalyAges Any age - NCT06446336Recruiting
New score for diagnosing long biceps tendon injuries
This study is creating a new scoring system to help doctors better diagnose injuries to the long biceps tendon before surgery. If you are planning surgery for shoulder pain that hasn't improved with treatment, this research may help improve how your condition is managed.
Le HavreAges 18 years+ - NCT03639285Recruiting
Study of inherited leukodystrophy symptoms and outcomes

Common questions
- Are there clinical trials for diagnosis?
- Yes. Clin2 currently lists 920 recruiting diagnosis 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 diagnosis 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 diagnosis 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.
