This study looks at how liver function and scarring affect calcium buildup in arteries. It may help people waiting for a liver transplant understand these changes.
Nice, Alpes-maritimesAges 18 years+ - NCT06744296Recruiting
ctDNA surveillance for HPV-negative head and neck cancer
This trial uses a blood test to look for tiny bits of tumor DNA after treatment for head and neck cancer. It aims to see if this test can detect any remaining cancer cells early, so you and your doctor can make informed decisions.
Boston, MassachusettsAges 18 years+ - NCT04691284Recruiting
Test how the gut microbiome changes during major cancer treatment
This study looks at your gut “microbiome” (the bacteria in your intestines) while you receive high-dose chemotherapy and a stem cell transplant, or CAR-T cell therapy. Researchers hope to understand how these treatments affect the microbiome, which may relate to how well patients do.
Bratislava, SlovakiaAges 18 years+ - NCT05775458Recruiting
Study of treatments for aggressive brain tumor cell damage
This study looks at glioblastoma (GBM), a very aggressive brain tumor, and how “brain cell overload” (glutamate excitotoxicity) may affect tumor growth. It focuses on adults who are planned for complete tumor removal, followed by standard radiation and chemotherapy.
Milan, MilanAges 18 years+ - NCT06649253Recruiting
CD9 Gene and Relapse in Childhood B-ALL Study
This study looks at how a gene called CD9 might affect relapse in children with B-ALL. It involves extra blood or bone marrow tests to understand why some children relapse.
AngersAges birth–17 years - NCT06101303Recruiting
Endometriosis pain study using surgery and surveys
This study looks at pain in people with or without endometriosis who are having laparoscopic surgery. Researchers want to understand more about pelvic pain by collecting information before, during, and after surgery.
St Louis, MissouriAges 12–45 - NCT02391519Recruiting
Study how high altitude affects body energy signaling
This study compares how the body responds to high altitude around the time of a planned C-section, including a signal involved in energy use. It may help researchers understand why pregnancy and blood-vessel function can differ at higher elevations.
Aurora, ColoradoAges 18–45 - NCT01313442Recruiting
Give blood and tumor samples for gastrointestinal cancer research
This trial collects blood and tumor tissue from adults with cancer to help researchers study gastrointestinal cancers. If you’re eligible, your participation mainly involves donating samples for research purposes.
Bethesda, MarylandAges 18 years+ - NCT04804878Recruiting
Cancer care program for adults to help manage cancer
This study is a general cancer care program for adults (and in some cases people at risk for cancer). It aims to improve how cancer care is organized and delivered, and you may benefit from extra care support through the program.
Atlanta, GeorgiaAges 18 years+ - NCT04860453Recruiting
Family genetic testing study for patterns of different cancers
This study checks whether gene tests can help understand cancer risk in families where different relatives had different (discordant) cancers. It may help families and doctors better understand whether hereditary cancer risk is possible, even though some parts use routine standard care as a comparison group.
Cleveland, OhioAges 18–100 - NCT05159739Enrolling by invitation
Study of family genetic risk for joint implant infections
This study looks at whether certain families have a higher genetic risk for infections around joint implants. It may help researchers understand who is more at risk and how to prevent these infections.
Salt Lake City, UtahAges 18–100 - NCT04970472Recruiting
Urothelial bladder cancer sample collection for adults
This trial collects clinical samples from adults who have suspected or confirmed urothelial (bladder/urinary tract lining) cancer. It helps researchers study the disease and may support future improvements in diagnosis or treatment.
ToulouseAges 18–99 - NCT04931160Recruiting
Study for suspected Sjögren’s disease diagnosis
This study follows people who may have Sjögren’s disease to better understand how to diagnose it. If you have symptoms like dry eyes or dry mouth, this could help researchers confirm the diagnosis and learn what tests best explain it.
BrestAges 18 years+ - NCT00442195Recruiting
Sample collection study in healthy volunteers
This study collects small samples of blood and cells from the inside of your mouth. Depending on your age, it may also collect bone marrow and skin (for research lab testing). It’s mainly about research planning and analysis rather than treating a disease.
Bethesda, MarylandAges 8–99 - NCT07037082Recruiting
Understanding menstrual cycles to improve women's health
This study tracks menstrual cycles and daily symptoms using a smart ring and home tests. It aims to better understand normal cycles and help detect health issues early.
MontpellierAges 18–39 - NCT05844865Recruiting
GI cancer study using a lab tumor model from your surgery
This study uses a special lab model made from tumor tissue taken during a planned standard cancer surgery. It tests how well the lab model can represent your cancer, which may help researchers improve future treatments.
Orange, CaliforniaAges 18 years+ - NCT07863908Recruiting

Common questions
- Are there clinical trials studying Blood samples?
- Yes. Clin2 currently lists 684 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.
