Testing new ways to assess brain and behavior health
This study is developing and checking better tests to understand neurological (brain-related) and psychiatric (mental health) conditions. If you have a diagnosed brain or mental health condition—or you’re being considered as a healthy person—your results will help researchers see how well these assessments work.

Testing blood and joint fluid tests for hip or knee infection
This trial checks how accurate certain blood tests and joint-fluid (synovial) tests are at identifying infections around hip or knee replacements. It also looks at whether these tests are worth the cost, to help doctors choose the best next step.
BolognaAges 18 years+ - NCT06349642Recruiting
Testing a live tumor test for immune therapy response
This trial uses a special test on live tumor samples to see if it can predict how well immune checkpoint inhibitors (a type of immunotherapy) will work for different cancers. It may help doctors choose the best treatment for you.
Phoenix, ArizonaAges 18 years+ - NCT04732273Recruiting
Study tracking long-term health after childhood cancer
This study follows people in Switzerland who finished treatment for childhood or teen cancer to learn about their long-term health. It may help doctors better understand late effects and follow-up needs after cancer treatment.
BaselAges Any age - NCT06331364Recruiting
Treating lung infections with better antibiotic decisions in Sri Lanka
This study tests whether a new way of deciding when to use antibiotics helps patients with lower respiratory infections (like pneumonia or bronchitis) in Sri Lankan hospitals. If you were recently admitted with a new lung infection, you may be able to join.
BalapitiyaAges 14 years+ - NCT06305039Enrolling by invitation
Better hearing with two cochlear implants

Bethesda, MarylandAges 18–85 - NCT06308510Recruiting
Improving stomach cancer detection with a fluid test
This study tests whether looking for certain DNA changes in the fluid from your belly can help doctors find stomach cancer that has spread. The goal is to make standard tests more accurate so treatment can be better planned.
RotterdamAges 18 years+ - NCT06286085Recruiting
Comparing asthma tests in Portsmouth
This study looks at different ways to test for asthma. It uses data from patients who have already been evaluated at the Portsmouth asthma service, to see which tests work best for diagnosing asthma.
PortsmouthAges 18 years+ - NCT06292104Recruiting
Understanding POTS: A study on heart rate and standing
This study looks at how the body controls heart rate and blood flow in people with POTS (a condition that causes dizziness and a fast heart rate upon standing). It helps researchers understand POTS better by comparing patients with healthy volunteers.
Dallas, TexasAges 14 years+ - NCT06292299Recruiting
Breathing monitor study for children with sleep or breathing issues
This study looks at how well a new breathing monitor works for children with sleep problems, breathing pauses in newborns, or epilepsy. It may help doctors better understand breathing patterns without extra needles or blood tests.
Glasgow, Glasgow CityAges 1 minute–16 years - NCT06282588RecruitingPhase 2/Phase 3
Advanced imaging-guided treatment for high-risk prostate cancer
This trial uses a special PET scan (PSMA PET/CT) and a genetic test (Decipher) to decide the best treatment for high-risk prostate cancer that hasn't spread outside the pelvis. You'll receive standard radiation and hormone therapy, possibly with an extra drug (darolutamide).
Wilrijk, AntwerpAges 18 years+ - NCT06274268Recruiting
Sarcopenia and cancer treatment side effects study
This study looks at how muscle loss (sarcopenia) might affect side effects from cancer treatments. If you are starting a new cancer treatment, a CT scan before treatment can help doctors predict your risk of side effects.
ChambéryAges 18 years+ - NCT06245512Recruiting
Endometriosis markers in menstrual blood
This study looks for signs of endometriosis in menstrual blood collected with a menstrual cup. It could help find better ways to diagnose the condition.

Common questions
- Are there clinical trials for diagnostic?
- Yes. Clin2 currently lists 662 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.
