Finding new blood markers for heart disease
This study is looking for people who have had a heart attack or have heart failure to discover new markers in your blood that could help doctors better understand and treat heart disease. By collecting samples and health data, researchers hope to find clues that improve care for future patients.
Shanghai, Jing 'an DistrictAges 30 years+ - NCT03408964Recruiting
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+ - NCT06380686Recruiting
Head and neck cancer research platform
This trial is collecting information and blood samples from people with head and neck cancer that cannot be cured. It aims to learn more about the cancer and find better ways to treat it.
EssenAges 18 years+ - NCT06584357Recruiting
Digital and blood markers linked to brain scans in older adults
This study is looking for older adults (60–90) who are either cognitively normal, have mild cognitive impairment (MCI), or have mild-to-moderate Alzheimer's dementia. It aims to see how digital tests and blood-based markers relate to brain scans (amyloid and tau PET). You will need a study partner, undergo MRI and PET scans, and give blood samples.
Atlantis, FloridaAges 60–90 - NCT06816121Recruiting
Blood test for early lung cancer in high-risk smokers
This study is evaluating a blood-based test that might detect lung cancer early, before symptoms appear. Researchers are looking for heavy smokers who have no signs of cancer, as well as those with suspicious lung nodules or confirmed lung cancer, to see if a simple blood draw could help identify cancer sooner.
Oklahoma City, OklahomaAges 30–80 - NCT06884189Recruiting
Pesticide exposure study in apple orchard areas
This study looks at how people living or working around apple orchards are exposed to certain plant protection products (pesticides). By joining, you can help researchers understand potential health risks and improve safety guidelines.
BerlinAges 18 years+ - NCT06899152Recruiting
New tests to track liver health during radiation for liver cancer
This study tests new blood tests and MRI scans to see how well your liver works during radiation therapy for liver cancer. It may help doctors better plan treatment and monitor your liver health.
The Bronx, New YorkAges 18 years+ - NCT07125079Recruiting
Studying immune cells and a new treatment for ARDS
This study looks at how the immune system responds in people with ARDS (a severe lung injury) and tests a new treatment called PIP-2 in the lab to see if it might help. It aims to better understand lung injury and find new ways to treat it.
Philadelphia, PennsylvaniaAges 21–90 - NCT07203833Recruiting
Vasorin test for shock diagnosis and outlook
This study looks at a protein called vasorin in the blood to see if it can help diagnose and predict outcomes in people with severe shock in the ICU. It compares patients with septic shock (caused by infection) to those with shock from other causes.
AmiensAges 18 years+ - NCT07378709Recruiting
Blood markers for TACE-treated liver cancer
This study is looking for blood markers that may help doctors learn how well TACE treatment is working for liver cancer. You need to be scheduled for TACE and have a follow-up scan to participate.
BelgradeAges 18 years+ - NCT07666113Recruiting
Blood test for Alzheimer's disease detection in primary care

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.
