Recruiting studies
- NCT07705178Recruiting
MRI study of heart and lung health after childhood cancer
This study uses MRI scans to look at the heart and lungs of childhood cancer survivors to see if chemotherapy caused any long-term changes. It may help doctors better understand and manage late effects after treatment for leukemia or lymphoma.
ErlangenAges 3 years+ - NCT02972385Recruiting
Testing how genes affect warfarin dosing in Hispanic and Latino adults
This study looks at how a person’s genes may affect how they respond to warfarin, a blood-thinner, so dosing can be safer and more accurate. It specifically focuses on Hispanic and Latino adults.
Tucson, ArizonaAges 18 years+ - NCT03008525Recruiting
Testing vitamin D levels in body fat tissue during surgery
This study measures vitamin D (and related forms) in fat tissue samples taken during surgery. It compares people with obesity to people without obesity to understand how vitamin D is handled in fat.

Test an immune marker in primary Sjögren’s disease activity
This study looks at an immune reaction (called anti-Ro/SSA IgE) to see how active primary Sjögren’s disease is. It may help doctors better understand what’s driving symptoms and activity levels over time.
BourgoinAges 18 years+ - NCT03010124Recruiting
Biomarker testing in ovarian cancer to guide future treatment
This study looks at tumor tissue from ovarian cancer patients to find “biomarkers,” or lab signals, that may predict how the disease behaves or how it might respond to treatment. You may be asked for a biopsy of the relapsed (coming back) tumor or to use an existing archived tumor sample.
Villejuif, Val de MarneAges 18 years+ - NCT03268668Recruiting
Study brain clot makeup and blood markers after stroke
This study looks at the composition of a stroke blood clot and compares it with blood test results to understand treatment response, stroke cause, and prognosis. It may help doctors better predict outcomes and improve care after ischemic stroke.
BordeauxAges 18 years+ - NCT03283852Recruiting
Genetic study for certain childhood hormone and development disorders
This study looks for new genetic causes of certain “development disorders” that involve hormone problems and how the body develops at puberty. It may help families understand the root cause, which can guide future care and testing.
ParisAges Any age - NCT03423758Recruiting
Genetic study of eye diseases: PXF, angle-closure and open glaucoma
This study looks at blood or DNA-related factors that may explain why certain glaucoma and related eye conditions happen. It may help researchers understand risk and causes across different glaucoma types.
ViennaAges 21–105 - NCT03586518Recruiting
Non-contrast heart MRI test in dialysis patients
This trial checks whether a new kind of heart MRI (done without contrast dye) can help doctors see heart changes in people receiving hemodialysis. It may help improve how heart health is measured in dialysis care, especially for people with limited time.
Leicester, LeicestershireAges 18 years+ - NCT03631953RecruitingPhase 1
Test alpelisib plus trametinib for hard-to-treat meningiomas
This Phase 1 trial studies whether combining two targeted medicines—alpelisib and trametinib—can shrink or slow progressive meningiomas that have already been treated with standard surgery and radiation. If you qualify, you may help test a new treatment approach for tumors that keep growing.
MarseilleAges 18 years+ - NCT03773887Recruiting
Study of liver inflammation and healing in alcohol-related liver disease
This study compares patterns of liver inflammation and the liver’s healing ability in people with alcohol-related liver disease, using blood tests and (in most cases) a liver tissue sample. It may help doctors better understand what is happening in the liver and how it may recover.
LilleAges 18–70 - NCT03792659Recruiting
Myasthenia gravis registry for storing your health data
This trial is a registry that collects your clinical information and biological samples to help researchers better understand myasthenia gravis. You may benefit indirectly by helping studies that could improve future care for people with this condition.
New Haven, ConnecticutAges 18 years+ - NCT03825458Recruiting
Study tracking hepatitis B viral RNA in blood
This study builds a group of people to measure small hepatitis B “viral RNA” signals in the blood. The goal is to see if these measurements could help researchers find a functional cure and better understand who may respond over time.
LyonAges 18 years+ - NCT03919981Recruiting
Testing Cysteamine for cystinosis bone health
This study looks at how cysteamine affects the bone health of people with nephropathic cystinosis, a rare genetic condition. It includes children and adults who are already taking cysteamine by mouth and will follow the study plan closely.
BesançonAges 2 years+ - NCT03981003Recruiting
Blood tests to track brain and nerve changes in MS
This study measures blood markers (from a serum blood sample) to see how nerve and brain changes relate to MS disease activity and disability over time. It may help researchers better monitor MS, especially in people followed in the OFSEP program.
AmiensAges 15 years+ - NCT03994497Recruiting
Testing a blood marker to predict rejection after kidney transplant
This study looks at a specific marker on immune cells (called CD45RC on T lymphocytes) to see if it can predict when a kidney transplant might reject. If you’re at lower immunologic risk, your blood tests could help doctors spot rejection risk earlier.
AngersAges 18–70 - NCT03998020Recruiting
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+ - NCT04363983Recruiting
Study of immune and tumor interactions in digestive cancers
This study looks at how tumors in the digestive system interact with the body’s immune system and the surrounding environment. Results may help improve understanding of these cancers and guide future treatments.
Boulogne-BillancourtAges 18 years+ - NCT04012411Recruiting
Testing brain fluid biomarkers in Huntington’s disease

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