Blood tests to predict treatment response in prostate cancer
This study checks whether certain blood markers can help predict how well people with prostate cancer will respond to therapy. It may help doctors choose the most effective treatment sooner by using information from your blood.
BellinzonaAges 18 years+ - NCT06050304Recruiting
Crack cocaine use and behavioral sensitization study
This study looks at how your body and mind might get more sensitive to crack-cocaine over time (behavioral sensitization) and what you expect from using it. Your participation helps us better understand addiction patterns.
ParisAges 18 years+ - NCT07717567Recruiting
Blood tests to diagnose and predict Alzheimer's disease
This study is testing whether a simple blood test can help diagnose Alzheimer's disease and predict how the disease will progress. If you have memory or thinking problems that have been getting worse, you may be able to join.
Milan, MilanoAges 40 years+ - NCT04439708Recruiting
Biomarkers for abnormal eye blood vessels
This study is looking for biomarkers (clues in your body) related to abnormal blood vessels in the eye. It may help researchers understand and treat conditions like macular degeneration.
ParisAges 18–90 - NCT07666711Recruiting

Oslo, OsloAges 18 years+ - NCT02168868Recruiting
Blood tests to find autism-related protein signals
This study looks at blood samples from children (and sometimes parents) to see if certain protein patterns can help identify or better understand autism spectrum disorder. The results could support finding “biomarkers,” which are measurable signs that may guide future research or care.
JerusalemAges 10 months–19 years - NCT05768399Recruiting
Study uses blood or test markers to track childhood asthma
This study looks for biological “markers” that may help explain why asthma starts and how it changes over time in children. It may help your child’s doctors understand asthma better, especially for diagnosis or tracking.
Chongqing, Chongqing MunicipalityAges 4–12 - NCT07875582Recruiting
Blood test for better pancreatic cancer diagnosis
This study looks for proteins in the blood that could help doctors tell the difference between pancreatic cancer and non-cancerous pancreatic conditions, such as chronic pancreatitis or benign cysts. By participating, you could help improve early and accurate diagnosis, which may lead to better outcomes for future patients.

Common questions
- Are there clinical trials for biomarkers / blood?
- Yes. Clin2 currently lists 222 recruiting biomarkers / blood 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 biomarkers / blood 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 biomarkers / blood 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.
