Blood test for Alzheimer's compared with spinal fluid test
This study is testing a simple blood test (p-Tau217) as a possible way to diagnose Alzheimer's disease. If it works, it might replace the need for a spinal tap. The results will be compared with the usual spinal fluid markers.

Blood tests to learn about cancer and treatment
This study collects extra blood samples during your routine care to look for markers that might help predict how well cancer treatments work and how long people live. Participating involves no extra procedures beyond what you already need.
NiceAges 18 years+ - NCT03124303Recruiting
Testing ways to measure and prevent delirium after surgery
This study looks at interventions to help with “postoperative delirium,” a sudden confusion that can happen after surgery, and uses brain measures like EEG and optional MRI. It may help doctors identify who is at risk and learn what approaches are most helpful after surgery.
Madison, WisconsinAges 60 years+ - 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.
Paris, Île-de-France RegionAges 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 - NCT02727803RecruitingPhase 2
Personalized natural killer cell therapy for blood cancers
This trial tests a customized immune-cell treatment (NK cells) for certain blood cancers to try to control or eliminate cancer cells. You may qualify if your cancer has come back, did not fully respond, or has higher risk features.
Houston, TexasAges 15–80 - NCT07091799Recruiting
Blood test to diagnose ALS using P2X4 markers
This study looks at a protein called P2X4 on immune cells in your blood to see if it can help diagnose ALS. You would give a blood sample to help researchers find a new way to identify ALS.
BordeauxAges 18 years+ - NCT06323876Recruiting
Using CT scans to personalize treatment for pulmonary fibrosis
This study uses detailed CT scans to find better ways to treat idiopathic pulmonary fibrosis (IPF). It may help doctors choose the right treatment for each person.

Biomarkers for memory decline after brain hemorrhage
This study looks for biological signs that might predict memory problems after a brain bleed, which could help doctors provide better care.
Chicago, IllinoisAges 18–80 - NCT06809673Enrolling by invitation
Blood markers in head and neck cancer surgery
This study looks at whether certain blood tests can help predict how head and neck cancer will respond to treatment. If you are planning surgery for squamous cell cancer of the throat, voice box, or mouth, this trial may offer more information about your outlook.
GenoaAges 18 years+ - NCT06613334Recruiting
Voice recordings to predict schizophrenia relapse
This study tests whether voice recordings can help predict when someone with schizophrenia might have a relapse. It is for people who are stable now and take certain medications.
Paris, ParisAges 18–60 - NCT05505669Recruiting
Blood test study to track markers in diabetes
This study measures “circulating biomarkers” (blood-based signals) in people with type 1 or type 2 diabetes, and in some people without diabetes who test positive for certain diabetes antibodies. The goal is to understand what these blood signals can tell us about diabetes development and progression.
Duarte, CaliforniaAges Any age - 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+ - NCT06863805Recruiting
Blood markers in advanced thyroid cancer
This study is looking at how certain substances in the blood (called biomarkers) can help doctors understand and treat advanced thyroid cancer. It is for people who are about to start their first systemic therapy (medication that works throughout the body) for advanced thyroid cancer, and who have already had a genetic test on their tumor.
BolognaAges 18 years+ - NCT04666402Recruiting
Testing better ways to diagnose early liver disease
This study looks at integrated diagnostic tests to find early liver problems sooner. It may help you (if referred to the community liver clinic) get more timely information about what’s going on.
Manchester, Greater ManchesterAges 18 years+ - NCT06223906Recruiting
Heart valve disease marker study
This study will collect information and blood samples from people with heart valve disease to find biological markers that may help doctors better understand and treat the condition in the future.
Beijing, Beijing MunicipalityAges 18–100 - NCT07063719Recruiting
Finding cell markers for rare eye diseases in adults
This study looks for biological markers in the blood or eye samples of people with rare eye diseases compared to healthy volunteers. It aims to better understand and diagnose these conditions.
ParisAges 18 years+ - NCT04904146Recruiting
Testing blood or tumor markers in skin lymphoma patients
This study looks for “predictive” and “prognostic” biomarkers—measurable signs in blood or tissue—to help predict how mycosis fungoides or Sézary syndrome will behave and how patients may respond to care. It may help doctors better understand outcomes for people with these skin lymphomas.
LundAges 18–100 - NCT07740967Recruiting
Collagen and omega supplements for middle-aged women
This study tests whether daily collagen and omega-3 supplements can improve health in healthy middle-aged women. You would take the supplements for a period and have your health measured.
LoughboroughAges 35–65 - NCT06023576RecruitingPhase 2
Blood pressure control during breast cancer chemo
This study tests whether careful blood pressure management can help protect the heart during certain types of chemotherapy (anthracyclines) for breast cancer. Participants will use a smart blood pressure device and may also do an exercise test.

Testing blood and tumor markers to guide lymphoma treatment
This study looks at “biomarkers” (measurable signs in your tumor and possibly blood) to understand your lymphoma’s genetic make-up. The goal is to see which markers may help doctors decide on treatment and timing.
DijonAges 18 years+ - NCT05383339Recruiting
Testing blood markers in autoimmune, vasculitis, and autoinflammation
This study looks at blood “biomarkers,” or measurable body signals, in people with autoimmune diseases, vasculitis, or autoinflammatory conditions. The goal is to better understand these illnesses and how they relate to disease activity.

Biomarkers in advanced liver cancer treated with tremelimumab/durvalumab
This study is looking for people with advanced liver cancer (hepatocellular carcinoma) who have not yet had systemic treatment. Participants will receive a combination of two immunotherapy drugs: tremelimumab and durvalumab (the STRIDE regimen). The goal is to find biomarkers that can predict how well the cancer responds to this treatment.

Common questions
- Are there clinical trials for biomarkers / blood?
- Yes. Clin2 currently lists 222 recruiting biomarkers / blood studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a biomarkers / blood trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a biomarkers / blood trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
