This study looks at the genetic information (DNA) from your blood and from saved tumor tissue to better understand certain cancers, especially rare cancers with a poor outlook. It may help researchers learn why these cancers behave the way they do and guide future treatments.
Brick, New JerseyAges 1 year+ - NCT07608835Recruiting
Lung Cancer Biomarkers and Immune Treatment Study
This study looks for biological markers (special signs in your body) that could help doctors choose better immune-based treatments for non-small cell lung cancer. Researchers will study your tumor and blood to understand which patients might benefit most from immunotherapy.

Understanding RFC1-ataxia to find biomarkers
This study looks at a rare genetic condition called RFC1-ataxia (also known as CANVAS). It aims to find better ways to diagnose and track the disease. You may qualify if you have this condition, are between 18 and 80, and can agree to take part.
BolognaAges 18–80 - NCT07729930Recruiting
Creatine supplement study for healthy middle-aged women
This study is testing a creatine supplement (a substance that may help with energy and muscle function) in healthy middle-aged women. You may join if you are between 35 and 65, a non-smoker, and have a certain activity level.
LoughboroughAges 35–65 - NCT06547099Recruiting
Understanding new blood markers in memory loss and dementia
This study is looking for older adults (60+) to help researchers better understand how to detect and track memory changes and dementia. Participants will provide blood samples and other health information over time to identify new markers that might help with early diagnosis.
St Louis, MissouriAges 60 years+ - NCT04012411Recruiting
Testing brain fluid biomarkers in Huntington’s disease
This study looks at specific “biomarkers” (measurable signs) found in cerebrospinal fluid, to better understand Huntington’s disease. The results may help researchers track the disease and improve future tests or treatments.
MontpellierAges 18 years+ - NCT03371641Recruiting
Study of alcohol exposure effects in unborn babies
This study looks at unborn babies exposed to alcohol during pregnancy and compares them with babies not exposed. Researchers test a pregnancy blood marker to see whether it may relate to early brain changes in the baby.
RouenAges 18 years+ - NCT05854368Recruiting
Blood tests to detect early stomach changes and cancer
This study looks for a blood “signature” that can spot early, risky stomach changes (before cancer) and stomach cancer. It may help clinicians diagnose earlier and decide who needs closer follow-up.
Boulogne-BillancourtAges 18 years+ - NCT06197204Recruiting
Finding biomarkers in Langerhans cell histiocytosis
This study is looking for adults with Langerhans cell histiocytosis (LCH) and also for adults with certain lung conditions (like cystic lung disease or emphysema) or healthy smokers to act as controls. The goal is to find biomarkers (signs in the body) that can help doctors diagnose LCH, predict how it will progress, and see how well treatment is working.
ParisAges 18 years+ - NCT07305090Recruiting
Gut GVHD biomarker study for transplant patients
This trial aims to develop a test using multiple biomarkers to predict how well patients will respond to treatment for acute graft-versus-host disease (GVHD) affecting the gut. It focuses on patients who are receiving an allogeneic stem cell transplant.
Bologna, BolognaAges 12 years+ - NCT04517656Recruiting
Testing blood markers after a bone marrow donor transplant
This trial checks how certain blood “biomarkers” change after you receive donor stem cells to rebuild your blood and immune system. The goal is to learn whether these markers can better predict your immune recovery after transplant.
Saint-EtienneAges 18 years+ - NCT06694363Recruiting
New test to guide treatment for APDS immune disorder
This study uses a new blood test to find and monitor people with APDS, a rare immune disease, who may be helped by the drug leniolisib. It aims to improve how doctors screen and track treatment response.

Blood test study for traumatic brain injury in kids
This study is testing whether a blood test can detect traumatic brain injury (TBI) in children. If successful, it could offer a quicker, less invasive way to diagnose concussions and other head injuries, reducing the need for CT scans or MRIs.
Omaha, NebraskaAges Up to 17 years - NCT03323216Recruiting
Testing heart-related blood markers in people with diabetes and heart failure
This study looks for blood markers that may help explain or predict heart problems in people who have type 2 diabetes and heart failure. To join, you may also need to be having a planned heart procedure where doctors can collect study information.

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.
