Recruiting studies
- NCT06582199Recruiting
Personalized Alzheimer's study using brain scans and spinal fluid
This study looks at how to better predict and understand Alzheimer's disease by using advanced brain scans and spinal fluid tests. It aims to find ways to identify people who stay healthy longer despite risk factors.

Using ctDNA to guide radiotherapy for head and neck cancer
This study looks at whether measuring a DNA fragment in the blood (called ctDNA) can help predict how well radiotherapy works for head and neck cancer. It may help doctors better tailor treatment for patients with stage III or IV disease.
Caen, CaenAges 18 years+ - NCT06474182Recruiting
Apixaban for blood clots in myeloma patients
This study looks at how Apixaban (a blood thinner) works in people with newly diagnosed multiple myeloma. It compares them to people having knee replacement surgery. The goal is to see if the drug prevents clots effectively in both groups.

Long-read genetic testing for undiagnosed cerebellar ataxia
This study uses a new, more detailed genetic test (long-read sequencing) to find the cause of inherited or early-onset balance disorders (cerebellar ataxias) when standard genetic testing has not provided answers. It may help you and your family understand why the condition occurs.
DijonAges Any age - NCT06474169Recruiting
T-cell study in long-term kidney failure
This study is looking at how immune cells called T-cells work in people with long-term kidney failure. It tests whether these cells can be changed in the lab to help treat the condition.
OrléansAges 18 years+ - NCT06470997Recruiting
Biomarkers for hepatitis from immunotherapy
This study looks for certain markers in the blood that can help diagnose liver inflammation caused by immunotherapy. It aims to better understand this side effect and how to treat it.
Montpellier, FranceAges 18 years+ - NCT05099341Recruiting
Study blood HDL differences in depression
This study compares a special type of cholesterol in the blood (HDL) between people with depression and people without depression. Researchers want to understand how depression may be linked to differences in HDL and related blood markers.
DijonAges 18 years+ - NCT06444646Recruiting
Studying fat cell particles in obesity
This study looks at tiny particles released from fat tissue in people with and without obesity. It aims to understand differences that might help explain obesity-related health problems.
Genk, LimburgAges 18–65 - NCT06442592Recruiting
Understanding development in kids with heart defects
This study looks at how children with complex congenital heart defects develop, especially their brain and learning skills. It will help doctors provide better support for these children.
Brest, Brittany RegionAges 3–11 - NCT06446947Recruiting
Blood markers for poor outcomes after sepsis in cancer surgery
This study looks at blood markers (epigenetics) to better understand why some people have a harder time recovering from a severe infection after major cancer surgery. The goal is to find early signs of poor outcomes in men aged 45–75 with post-surgery sepsis.
Marseille, Bouches du RhôneAges 45–75 - NCT05534347Recruiting
Blood marker study in teens with juvenile arthritis
This study looks at blood (and related) markers that may reflect inflammation in people with juvenile idiopathic arthritis. It may help doctors better understand disease activity and guide future care for patients who are able to join.
Paris, IDFAges 16 years+ - NCT06430021Recruiting
Blood test for neuroendocrine tumors in MEN1
This study is testing a new blood test to see if it can help diagnose neuroendocrine tumors in people with MEN1, a genetic condition that increases the risk of these tumors. The test looks for a protein called hPG80 (progastrin) and may help doctors find tumors earlier.
DijonAges 18–60 - NCT06434207Recruiting
Heart defect study in newborns to understand blood clots
This study looks at tiny particles from cells in newborns with heart defects to understand blood clot risks. It aims to find ways to prevent clots after heart surgery.

Testing uterine fluid to help detect ovarian cancer
This study checks whether a sample of fluid from the uterus (uterine lavage) can help detect ovarian or fallopian tube cancer. You may join if you are having certain gynecologic surgeries or, in a smaller group, you have a BRCA1/2 mutation.
Little Rock, ArkansasAges 30 years+ - NCT06408701Recruiting

Common questions
- Are there clinical trials studying Blood sample?
- Yes. Clin2 currently lists 684 recruiting studies that include Blood sample, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Blood sample trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Blood sample an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Blood sample or a specific trial is right for you.
