Recruiting studies
- NCT04837339Recruiting
Testing markers to predict problems after lung transplant
This study looks for lab “clues” that can help predict how well someone’s lungs will do after a lung transplant. It may help doctors spot transplant-related problems earlier so care can be planned sooner.

Study of young cancer survivors followed at a Swiss hospital
This study looks at the experiences and health of people who finished childhood cancer treatment and are (or were) followed by Kantonsspital Aarau. It mainly involves sharing and reviewing medical information to understand survivorship after cancer.

Join a children’s genomic sample and data library
This study collects and stores DNA samples and related health information from people of all ages. It helps researchers understand childhood diseases better and may support future discoveries and treatments.
San Diego, CaliforniaAges Any age - NCT04032379Recruiting
Study biomarkers to predict outcomes in idiopathic intracranial hypertension
This study looks at body measurements (“biomarkers”) to help doctors diagnose idiopathic intracranial hypertension (IIH) and predict how it may go over time. If you’re an adult with a doctor’s concern for IIH, you may be asked to provide health information and possibly samples for testing.
Copenhagen, GlostrupAges 18 years+ - NCT05752682Recruiting
Check care for fainting or falls in adults over 40
This trial tests a “global” approach to assessing episodes of fainting or falling in people age 40 and older. It may help doctors find the right cause and safer next steps after an episode.
Milan, MIAges 40 years+ - NCT04737317Recruiting
Check criteria to diagnose cardiac sarcoidosis
This study tests how doctors can best tell whether someone has cardiac sarcoidosis, a condition where inflammation affects the heart. It may help you get a more accurate diagnosis using expert guidelines and special heart tests, and it groups patients as proven, probable, or unlikely.
LeipzigAges 18 years+ - NCT05937334Recruiting
Long-term study of asthma in adults in China
This study follows adults with asthma over about 2 years to learn more about asthma and how people do over time. If you qualify, you’ll be asked to join regular visits and follow the study plan.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05955859Recruiting
Testing how to diagnose fungal sinus infections
This study looks at better ways to diagnose a fungal (mycotic) infection in the sinus/near-nose area. You may be considered if you have symptoms on only one side, such as blockage or drainage, and you can safely take part in the study tests.
Ostrava, Czech RepublicAges 18–80 - NCT06020625Recruiting
Genetic testing for advanced cancers
This trial investigates genetic testing (mutational profiling) in people with various advanced cancers. It aims to understand how these tests can guide more personalized treatment decisions.
RomeAges 18 years+ - NCT06074731Recruiting
Eye imaging study using a new scanner
This trial uses a special eye scanner to look at eye diseases. It might help doctors see eye problems more clearly.
Linz, Upper AustriaAges 5–110 - NCT05827406Recruiting
Support system for psychiatric checkups in adults
This study looks at a helpful support system to improve how psychiatric symptoms are diagnosed and followed over time. It may help patients and clinicians by making checkups and next steps more organized.
StockholmAges 18 years+ - NCT04923191Recruiting
Test heart-procedure guidance from scans versus usual care
This study compares two ways of guiding a heart stent procedure: using information from a special angiography scan versus using standard practice. It may help your care team choose the best treatment to improve heart outcomes after stenting.
AalstAges 18 years+ - NCT06129656Recruiting
Cardiac Amyloidosis Registry at Leipzig Hospital
This study is a registry that collects information from people with cardiac amyloidosis. It helps doctors learn more about the condition and how to better treat it.
Leipzig, SaxonyAges Any age - NCT05698901Recruiting
Testing heart blood tests and scans to monitor Fabry disease
This study checks whether certain heart-related blood tests and heart scans can help monitor people with Fabry disease. It may be useful for both people who have never received enzyme replacement therapy and those who have.
TaipeiAges 18 years+ - NCT05985668Recruiting
Better diagnosis for platelet function disorders
This study aims to improve how doctors diagnose platelet function disorders—problems with blood cells that help stop bleeding. If you have a known or suspected platelet disorder and are being seen at Karolinska University Hospital, this trial may offer better testing to find the cause of your bleeding issues.
StockholmAges 1 year+ - NCT06167629Recruiting
PSMA PET scan study for prostate cancer
This study uses a special type of PET scan called PSMA PET to better understand and track prostate cancer. The scan helps doctors see where the cancer is in the body and if treatment is working.
MilanAges 18 years+ - NCT06094660Recruiting
Nerve blocking for knee arthritis pain
This study tests two treatments for knee arthritis pain when knee replacement isn't an option: a nerve block using heat (radiofrequency ablation) or a chemical injection (phenol), compared to standard care. It aims to find a better way to reduce pain and improve daily function.
Hoorn, North HollandAges 35–90 - NCT06170268Recruiting
Alzheimer's registry for treatment and diagnosis
This registry collects information from people with mild cognitive impairment or dementia due to Alzheimer's disease who are being treated with new FDA-approved therapies. The goal is to track how these treatments work in everyday medical practice.
Chicago, IllinoisAges 18 years+ - NCT06155318Recruiting

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.
