How psychoactive drugs affect fall severity in older adults
This study looks at older adults who fall while taking certain medications that affect the brain, like sedatives or antidepressants. It aims to understand if these drugs make falls more serious and how they can be better managed.
CaenAges 75 years+ - NCT05710679Recruiting
Blood test predicts leftover cancer after intensified head and neck radiation
This study uses a blood test to see whether cancer DNA is still detectable after a stronger combination of radiation and chemotherapy for locally advanced head and neck cancer. The goal is to predict who may have “residual” (remaining) disease and help guide future care.
Clermont-Ferrand, Puy-de-DômeAges 18–80 - NCT05267379Recruiting
Study of causes of pancreatitis after ERCP
This study looks at how genes and medication processing in the body may relate to getting pancreatitis after an ERCP procedure. If you are having an ERCP and meet the criteria, your data and possibly samples may help researchers understand who is at higher risk.
Nijmegen, GelderlandAges 18 years+ - NCT05283174Recruiting
Blood thinner use during stroke to predict outcomes
This study looks at how people doing well on certain blood thinners do when they have a stroke or bleeding while taking them. It will measure medication levels in your blood to understand stroke severity and recovery in the short and long term.
TaipeiAges 20 years+ - NCT05343286Recruiting
Personalized exercise plan for older adults
This study looks for health “signals” that can help tailor a physical activity program for people aged 60 and older. It may help decide which exercise approach works best for different individuals over time.
NiceAges 60 years+ - NCT05567289Recruiting
Precision medicine after stem cell transplant
This study looks at a personalized (“precision”) approach for people who have received a stem cell transplant from a donor. It may help doctors better tailor care after transplant, especially for children.
ManchesterAges Any age - 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+ - NCT05089747Recruiting
Study uses extra blood samples for solid cancer patients
This study looks at how blood can help us better understand solid cancers. You may be able to join if you’re an adult with solid cancer and your usual care already involves taking blood, and you can safely provide samples for the study.
BronAges 18 years+ - NCT04638725Recruiting
Genetics study to find why HER2 breast cancer treatment varies
This study looks at genetic factors to understand why some people’s HER2-positive breast cancer responds better—or has more side effects—after treatment. Your info and possible past treatment history may help researchers improve how HER2 treatment is chosen and managed.
StrasbourgAges 18 years+ - NCT03925311Recruiting
Checking how the uterus is prepared for pregnancy
This study looks at patterns in the uterus and the uterine lining to understand how ready the uterus is for pregnancy. You may be able to join if you are within a specific age range and don’t have certain common uterine conditions.
Hong KongAges 20–40 - 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+ - NCT02444416Recruiting
Registry study for people with new acute heart failure
This study is a registry that collects information about people who come to care with sudden (acute) worsening heart failure symptoms. If your test shows a higher BNP level, your doctors may use your details to better understand and track acute heart failure care.
GenevaAges 16–100 - NCT05089162Recruiting
Testing a heart ultrasound approach in chronic heart failure
This study looks at people with chronic heart failure with weaker pumping function and checks how well a lung/heart ultrasound can assess congestion (fluid buildup). If you qualify, you may help test a better way to evaluate your condition during a planned hospital visit.
Vandœuvre-lès-NancyAges 18 years+ - 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+ - NCT04343430Recruiting
Hospital study for fluid buildup in heart failure with preserved heart function
This study looks at how well doctors can assess fluid buildup before you leave the hospital if you have a type of heart failure called “preserved ejection fraction.” It may help improve decisions about when and how safely people are discharged.
Vandœuvre-lès-NancyAges 18 years+ - NCT04392401Recruiting
Study immune changes in adults during ICU stay for COVID-19
This study looks at how your immune system responds while you’re in the intensive care unit (ICU) for COVID-19. Researchers will collect samples early in the ICU stay to better understand immune changes during the illness.
BronAges 18 years+ - NCT04343443Recruiting
Test whether a lung ultrasound helps discharge planning after heart failure
This study looks at people hospitalized for worsening heart failure with weaker pumping (reduced ejection fraction). It tests whether a lung ultrasound evaluation near discharge can improve how doctors decide it is safe to send you home.
Vandœuvre-lès-NancyAges 18 years+ - NCT02397824Recruiting
Teeth photo study for people with rare diseases
This study looks at how rare diseases can show up in the mouth and teeth, using pictures of your teeth. It may help doctors recognize dental signs earlier and better describe these rare conditions.
Strasbourg, AlsaceAges Any age - NCT03492528Recruiting
Heart care study for people starting cancer treatment
This study follows adults who are referred to a heart (cardio-oncology) specialist before starting cancer treatment. It may help doctors better understand heart outcomes in people with cancer and improve how heart risks are managed early.
MarseilleAges 18 years+ - NCT07174141Recruiting
Heart risks from newer blood cancer drugs (acalabrutinib or zanubrutinib)
This study looks for early signs of heart problems in people taking newer targeted blood cancer drugs called acalabrutinib or zanubrutinib. By using special blood tests, doctors hope to catch and manage heart issues before they become serious.
DijonAges 18 years+ - NCT03518099Recruiting
Testing blood signals after sudden bowel blood flow injury
This study is looking for signs in the body (called biomarkers) after sudden loss of blood flow to the intestines. It involves getting a CT scan to check what is happening in the abdomen so the researchers can see which signals match intestinal injury.
ClichyAges 18 years+ - NCT01072825Recruiting
Study for adults with gender incongruence not on hormone therapy

Study of vaginal and uterine microbiome after frozen embryo transfer
This study looks at how bacteria in the vagina and lining of the uterus change during the “luteal phase” (the time after ovulation and before a pregnancy test) in people using frozen embryo transfers. It may help researchers understand what conditions support embryo implantation and pregnancy in assisted reproduction.

MRI study for heart health in liver transplant candidates
This study uses a special heart MRI to check for a heart condition called cirrhotic cardiomyopathy in people waiting for a liver transplant. The results may help doctors better understand and treat heart problems in patients with cirrhosis.

Common questions
- Are there clinical trials studying Blood samples?
- Yes. Clin2 currently lists 700 recruiting studies that include Blood samples, 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 samples 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 samples 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 samples or a specific trial is right for you.
