Recruiting studies
- NCT05649865Recruiting
Monitor HPV DNA in throat cancer to guide early response
This study checks a substance called HPV DNA in your blood to see how your HPV-positive throat cancer responds early during treatment. It may help doctors spot who is responding well and who may need closer attention sooner.

Predicting clot and bleeding risk in kidney disease patients after a heart attack
This trial tests whether a blood test looking at platelets and tiny cell particles can help predict future blood clots or bleeding in people who have both chronic kidney disease and a recent heart attack. The goal is to improve treatment safety.
MarseilleAges 18–90 - NCT04575363Recruiting
Testing a blood marker to predict pancreatic cancer outcomes
This study looks at a test called RPSA to see if it can help predict how pancreatic cancer may turn out. It includes people being treated at Reims University Hospital for pancreatic tumors that can be removed (or may become removable).
ReimsAges 18 years+ - NCT05029791Recruiting
Study of immune markers in treated metastatic melanoma
This study looks at immune and tumor “behavior” markers in people with metastatic melanoma after standard treatment. It may help researchers understand why treatment works for some people and not others by testing blood and skin tumor samples.

Blood markers in children with congenital hearing loss
This study looks at certain substances in the blood of children with congenital hearing loss (hearing loss present from birth) to see if they are different from children with normal hearing. It may help doctors understand why hearing loss happens and could lead to better treatments.

Sleep study group for people with long-lasting excessive sleepiness
This study is building a long-term group of people with chronic excessive sleepiness (hypersomnolence) so researchers can better understand rare sleep disorders and related biology. It involves sleep-focused assessments and questionnaires, and you may or may not be on treatment for sleep problems.
MontpellierAges 6 years+ - NCT06203496Recruiting
Monitoring brain tumors with blood tests
This trial studies whether a blood test can track the progress of a type of brain tumor called a grade 4 diffuse glioma. It may offer a less invasive way to monitor these tumors after surgery.
CaenAges 18 years+ - NCT05306834Recruiting
Study to slow memory decline by targeting hidden small brain vessel disease
This trial looks at how to slow cognitive decline and early dementia in people with a specific kind of “silent” blood vessel damage in the brain seen on scans. It may help identify whether targeting this hidden condition can protect thinking and memory over time.
BordeauxAges 60–88 - NCT05824442Recruiting
Testing a new PCR test for echinococcosis diagnosis
This study checks whether a new lab test (a PCR blood/tissue test) can more accurately diagnose echinococcosis. It may help doctors confirm the infection faster and more reliably so you can get the right treatment.
BesançonAges 18 years+ - NCT06183632Recruiting
Lipid study in healthy blood donors
This research study looks at tiny particles in the blood called microparticles and their fat content. It aims to understand these particles in healthy people, which helps in future research on diseases.
DijonAges 18 years+ - NCT07868640Recruiting
Blood test validation for multiple cancer types
This study collects blood samples from people being treated for certain cancers to check if a new blood test (TST79) can help detect or monitor cancer. If you have one of the listed cancer types and are currently receiving treatment, you may be able to take part.
Charleroi, HainautAges 18 years+ - NCT06277466Recruiting
Gene changes and diabetes risk study
This study looks at how certain gene changes affect blood sugar control in type 2 diabetes and also in people who have had pancreas surgery. It compares these groups with healthy volunteers to see how genes influence the risk of diabetes.
XuzhouAges 25–70 - NCT07872670Recruiting
Virtual reality to help recovery after hip or knee replacement
This study uses virtual reality (a computer-generated 3D environment you wear a headset for) alongside your usual care to help with recovery after hip or knee replacement surgery. It may help reduce pain or improve how well you move after surgery.
Inverness, HighlandsAges 18 years+ - NCT05714241Recruiting
Blood tests to study heart pain with blocked-unblocked arteries
This study looks at blood “biomarkers” and platelet function to better understand INOCA (heart-related chest pain despite no major artery blockage). You may be eligible if you have INOCA and are already taking aspirin, and if you haven’t taken certain blood-thinner or platelet-altering medicines recently.
RomeAges 18 years+ - NCT05750147Recruiting
Study for cardiomyopathy linked to family or genes
This study looks at people with cardiomyopathy (or related heart muscle conditions) and those who may be at risk because of family history or genetic test results. It may help researchers better understand who is likely to develop the condition and how best to monitor or support them.
LondonAges Any age - NCT06317467Recruiting
Anti-C1q antibodies and pregnancy outcomes study
This study looks at a specific antibody (anti-C1q) in pregnant women, including those with normal pregnancies, preeclampsia (high blood pressure and protein in urine after 20 weeks), or autoimmune conditions like lupus or antiphospholipid syndrome. The goal is to understand how this antibody might affect pregnancy and help guide care.
TriesteAges 18 years+ - NCT06355245Recruiting
Early cancer detection study for unexplained symptoms
This study looks for early signs of cancer in people who have unexplained symptoms like extreme tiredness, weight loss, fever, or abnormal lab tests. You will be monitored and tested to see if markers can find cancer sooner.

Can blood tests improve lung cancer screening in smokers with artery disease?
This study looks at whether certain blood tests can help find lung cancer early in people who have smoked for a long time and also have artery disease. The goal is to see if adding these tests to current screening methods can better identify those at highest risk.
MarseilleAges 45–80 - NCT04801654Recruiting

Common questions
- Are there clinical trials studying Blood sampling?
- Yes. Clin2 currently lists 684 recruiting studies that include Blood sampling, 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 sampling 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 sampling 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 sampling or a specific trial is right for you.
