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+ - 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.
BordeauxAges 12 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+ - NCT06940232Recruiting
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.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT06102694Recruiting
Blood test to find early signs of a transplant complication
This trial looks for proteins in the blood that could help detect transplant-related blood vessel damage (called TMA) earlier, so doctors can treat it faster. It involves patients who have had a stem cell transplant from a donor.
TianjinAges 14–70 - NCT06870435Recruiting
Screening for nasopharyngeal cancer with blood tests
This study compares three different blood tests to see which works best for spotting nasopharyngeal cancer early in people at higher risk. If you live in certain areas of China, you may be able to join.

Studying nerve damage from chemotherapy in colorectal and lung cancer patients
This study looks for small molecules in the blood that might predict nerve damage caused by certain chemotherapies. If you have colorectal or lung cancer and are starting a specific chemo plan, this trial could help researchers understand why some people get nerve problems and others don't.
Clermont-FerrandAges 18 years+ - NCT06869564Recruiting
Blood test study for acute mesenteric ischemia diagnosis
This pilot study looks at markers in your blood that might help doctors tell if you have a serious bowel condition called acute mesenteric ischemia. You may be asked to participate if you have severe belly pain and need a special CT scan to check for this condition.

RAI1 gene disorder study: biomarkers and clinical features
This study looks at people with a rare genetic condition caused by changes in the RAI1 gene. Researchers want to learn more about the condition and find markers that could help with future treatments. You and a healthy family member will spend one day in Houston for tests and samples.

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.
