Clonal blood changes after certain lung blood clots
This study looks at whether a specific kind of blood-cell change (“clonal hematopoiesis”) is linked to a lung blood clot (pulmonary embolism) that happened without a clear trigger. It compares people with unprovoked clots to people with provoked clots, after checking for inherited clotting risk factors.
AmiensAges 18–65 - NCT04732156Recruiting
Test AI and MRI scores to spot prostate cancer
This study compares how well a doctor’s MRI reading (the PI-RADS score) and a computer AI tool detect prostate cancer. It may help improve how men get targeted biopsies and avoid missing important cancers.
BordeauxAges 18–80 - NCT04772963Recruiting
Genetics study for brain blood vessel malformations
This study looks at genetic (inherited DNA) factors in people with certain abnormal blood vessel connections in the brain or spinal cord. It may help researchers understand why these malformations happen and how they might behave over time.
ParisAges Any age - NCT04791540Recruiting
Rehab study for people with a tracheostomy and low muscle strength
This study looks at how nutrition and muscle health affect recovery during rehabilitation for people who have a tracheostomy (a breathing opening in the neck). It may help the rehab team improve food and care plans to support strength and overall health.
Florence, ItalyAges 18 years+ - NCT04794322Recruiting
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+ - NCT04798651Recruiting
Study immune blood and spinal fluid cells in multiple sclerosis
This study looks at different immune cells in blood and, sometimes, spinal fluid (CSF) to understand what’s driving multiple sclerosis (MS) or early MS-like symptoms. Your participation may help researchers better explain the disease and potentially improve how it’s diagnosed or treated.
BordeauxAges 18 years+ - NCT04800458Recruiting
Testing antibody findings to confirm autoimmune low platelets
This study looks at blood test antibodies to help confirm whether low platelet counts are caused by an autoimmune condition. It may help doctors better classify your type of low platelets and guide appropriate next steps.
PessacAges 18 years+ - NCT04809506Recruiting
Blood and genetic tests to predict future heart problems
This study looks for new body markers (including possible genetic traits) to better predict who is likely to have future cardiovascular events. Your results could help doctors estimate risk and choose prevention strategies more accurately.
ToulouseAges 18–99 - NCT04817072Recruiting
Studying mood changes in inflammatory arthritis patients on biologics
This study looks at how mood disorders (like depression or anxiety) affect people with chronic inflammatory joint diseases when they use biologic medicines. It may help doctors understand which patients are at higher mood-risk and how to monitor them.
BesançonAges 18–80 - NCT04823923Recruiting
How kidney failure affects drug levels in metastatic kidney cancer
This study looks at how chronic kidney failure changes the amount of certain cancer medicines in the blood. It involves people with metastatic clear cell kidney cancer who take pazopanib or cabozantinib, and compares drug levels in different kidney function groups.
MarseilleAges 18 years+ - NCT04857528Recruiting
Testing HPV DNA in anal and cervical tumors
This trial checks whether tumor samples contain HPV DNA (genetic material from the HPV virus). The goal is to improve detection in anal and cervical cancers, especially in patients planning standard radiation treatment.
Chicago, IllinoisAges 18 years+ - NCT04925349Recruiting
Study blood immune patterns in several rare brain diseases
This study looks at immune cells in blood to better understand rare brain conditions caused by genetic changes. It may help researchers understand why symptoms happen and how the immune system is involved.
Le Kremlin-BicêtreAges 1.3 years–60 years - NCT04925856Recruiting
Monitoring the immune system during breast cancer drug treatment
This study looks at how your immune system changes while you receive standard breast cancer treatments. The researchers measure immune-related signals during your treatment to better understand what may be happening in triple-negative or certain hormone-receptor breast cancers.
BesançonAges 18–85 - NCT04067674Recruiting
Study immune changes in adults with septic shock
This trial looks at how the immune system changes after septic shock in adults in the ICU. It may help doctors better predict or manage complications by studying blood markers a few days after starting treatment.
LyonAges 18 years+ - NCT07511959Enrolling by invitation
Blood-derived treatment for chronic jaw pain
This trial tests whether a treatment made from your own blood (platelet-rich plasma exosomes) can help relieve long-term jaw joint pain and improve function. If you qualify, you would receive injections directly into your jaw area.
WroclawAges 18 years+ - NCT07695545Recruiting
Lipid metabolism study in ascending aortic aneurysm
This study looks at how fat metabolism and cell energy centers (mitochondria) work in patients having surgery for an ascending aortic aneurysm. It aims to understand differences between people with bicuspid or tricuspid aortic valves.
DijonAges 18 years+ - NCT04946916Recruiting
Testing blood/brain marker levels and thinking problems in psychiatric illness
This study looks at neurofilament light (a brain/nerve injury marker) and how it relates to thinking and memory problems in people with certain psychiatric conditions. It may help researchers understand brain changes and cognitive impairment, which could guide better diagnosis in the future.
BronAges 45–80 - NCT04971564Recruiting
Blood inflammation test study in sudden brain oxygen loss
This trial looks at blood “inflammation-related” biomarkers to understand what happens early after certain sudden brain events. It may help doctors predict outcomes and tailor treatment for people like those with stroke types that sometimes need a clot-removal procedure.

Common questions
- Are there clinical trials studying Blood sample?
- Yes. Clin2 currently lists 701 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.
