Find hidden DNA changes in some boys with unclear DSD
This trial looks for “structural variants,” meaning larger DNA rearrangements that standard gene tests may miss, in boys with certain differences in sex development (DSD) when results are unclear. It may help provide a clearer diagnosis that can guide care for your family.
MontpellierAges 6 months+ - NCT06239259Recruiting

Study of sinus disease in young children with cystic fibrosis
This study looks at sinus problems in young children with cystic fibrosis. One group of children starts a new medicine called a highly effective modulator (like Trikafta), and the other group does not take this medicine. The goal is to see how the medicine affects sinus health over time.

European registry for newly diagnosed AL amyloidosis
This study collects information and samples from people newly diagnosed with AL amyloidosis who have not yet received treatment. It aims to improve how this rare disease is diagnosed and managed across Europe.

FAPI PET scan for aggressive colorectal cancer liver metastases
This trial uses a special PET scan (FAPI) to detect a specific, more aggressive type of colorectal cancer (CMS4) in people who have liver tumors that can be surgically removed. The goal is to see if the scan can help doctors choose the best treatment for you.
Utrecht, UtrechtAges 18 years+ - NCT06162884Recruiting
Using one scan to predict early scarred lung disease
This study uses a single lung scan to find early signs of progressive scarring (fibrosis) in people with pulmonary fibrosis. It may help doctors predict which patients will get worse faster.
Los Angeles, CaliforniaAges 18 years+ - NCT06181409Recruiting
New scans to detect liver disease complications
This study uses two types of scans (MRI and ultrasound) to check for high pressure in the veins of your liver. It may help doctors find problems earlier without invasive tests.
Montreal, QuebecAges 18 years+ - NCT05784922Recruiting
Lung cancer screening support for eligible smokers
This study aims to improve and promote lung cancer screening for people at higher risk who may face barriers. You may be asked to share your experiences through surveys or focus-group style activities to help make screening more equitable.

Common questions
- Are there clinical trials for diagnosis?
- Yes. Clin2 currently lists 928 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.
