Las Vegas, NevadaAges 45–80 - NCT04925089Recruiting
Testing biomarkers in localized soft tissue cancer before surgery
This study looks at lab biomarkers (signs in tumor tissue) in people with localized leiomyosarcoma. It also requires treatment with chemotherapy before surgery to see if the information from tumor samples can help guide care.
Ann Arbor, MichiganAges Any age - NCT07375940Recruiting
Understanding Behçet Disease in children and teens
This study looks at the health records and blood tests of children and young adults with Behçet disease to learn more about the condition. It also compares their results with healthy children to find clues that may help doctors better understand and treat Behçet disease.
Florence, FlorenceAges 6 months–70 years - NCT07465848Recruiting
Testing telomere measurement to help diagnose lung cancer
This study uses a simple blood test to measure telomeres (parts of your DNA) to see if it can help detect lung cancer earlier. Researchers will compare results from people with lung cancer, heavy smokers, and low-risk individuals to improve diagnosis.
Elche, AlicanteAges 45 years+ - NCT06096766Recruiting
Ovarian function and blood markers study
This study looks at how certain blood markers relate to ovarian function in women with normal ovaries, diminished ovarian reserve (DOR), or primary ovarian insufficiency (POI). It may help doctors better understand these conditions.
BeijingAges 18–45 - NCT05743049Recruiting

Philadelphia, PennsylvaniaAges 18 years+ - NCT05924425RecruitingPhase 4
Daridorexant for insomnia in early memory decline
This trial tests whether daridorexant can improve sleep in people who have mild cognitive impairment or early Alzheimer’s disease and struggle with insomnia. It may help by improving how long and how well you sleep, with monitoring of sleep patterns and memory-related measures.

Common questions
- Are there clinical trials for biomarkers / blood?
- Yes. Clin2 currently lists 217 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.
