Testing telomere measurement to help diagnose lung cancer
This study uses a simple blood test to measure telomeres (parts of your DNA) to see if it can help detect lung cancer earlier. Researchers will compare results from people with lung cancer, heavy smokers, and low-risk individuals to improve diagnosis.
Elche, AlicanteAges 45 years+ - NCT06096766Recruiting
Ovarian function and blood markers study
This study looks at how certain blood markers relate to ovarian function in women with normal ovaries, diminished ovarian reserve (DOR), or primary ovarian insufficiency (POI). It may help doctors better understand these conditions.

This study collects blood samples from people who have recently broken a bone (within 7 days) to test a new way of measuring how bones heal. It may help doctors better understand recovery and guide treatment.
Sacramento, CaliforniaAges 18 years+ - NCT06856161Recruiting
Blood test to help diagnose mental health conditions
This study is testing a new blood test that might help doctors better understand and diagnose conditions like depression, psychosis, or schizophrenia. If you are 19 or older and have one of these conditions, you may be able to join.
New Westminster, British ColumbiaAges 19 years+ - NCT05924425RecruitingPhase 4
Daridorexant for insomnia in early memory decline
This trial tests whether daridorexant can improve sleep in people who have mild cognitive impairment or early Alzheimer’s disease and struggle with insomnia. It may help by improving how long and how well you sleep, with monitoring of sleep patterns and memory-related measures.
MontpellierAges 60–85 - NCT05595954Recruiting
Personalized anesthesia plan to protect the brain during heart surgery
This trial studies whether tailoring anesthesia and monitoring the brain’s blood-flow control during heart surgery can improve neurological outcomes (brain-related function and recovery). It may help by guiding anesthesia in a more individualized way and checking how well the brain is protected during the operation.
BaselAges 65 years+ - NCT06435468Recruiting
Biocollection for rare childhood-onset immune diseases
This study collects blood and tissue samples from patients with rare immune system diseases that started in childhood, and from their relatives and healthy volunteers. The goal is to build a biocollection for future research to better understand these diseases.
Bron, BronAges 1 year+ - NCT06790797Recruiting
Predicting immunotherapy success in chest cancers
This study is for people with lung or esophageal cancer who will receive immunotherapy (drugs that help your immune system fight cancer). The researchers want to find markers in your blood and tumor that can predict how well the treatment will work.
Suzhou, JiangsuAges 18–80 - NCT06624488Recruiting
Brain injury markers after cardiac arrest and outlook
This study looks at certain proteins in the fluid around the brain and in the blood after a cardiac arrest. These proteins may help doctors predict how the patient will recover, which could guide their care.
BeijingAges 18–80 - NCT06871800Recruiting
Blood tests to predict recovery after stroke or brain injury
This study looks at tiny particles in your blood called extracellular vesicles to see if they can help predict how well you will recover after a stroke or brain injury. If you are starting rehabilitation soon after your stroke, you may be able to join.
FlorenceAges 18 years+ - NCT07353502Recruiting
Early Alzheimer's brain connection study
This study looks at a specific brain pathway that may be linked to early memory loss in Alzheimer's disease. It compares people with early Alzheimer's to healthy older adults to understand how connections between brain cells start to break down.
Yiwu, ZhejiangAges 50 years+ - NCT05628974Recruiting
Healthy adults can donate blood for platelet testing
This study looks at how platelets work and checks blood markers using donations from healthy volunteers. It may help researchers design future platelet-related treatments and better tests.
Cleveland, OhioAges 18–65 - NCT05079399Recruiting
Diabetic eye screening study using eye scans
This study looks for specific eye findings (“biomarkers”) in people with type 2 diabetes using eye imaging. It may help researchers better understand diabetic retinopathy and how to detect it earlier or more accurately.
Carmel, IndianaAges 18 years+ - NCT04085900Recruiting
Screening test for nasopharyngeal cancer blood markers
This study screens people in certain cities to see whether signs in the blood related to a virus (EBV) can help find nasopharyngeal cancer earlier. It may help identify higher-risk people so they can be checked sooner.
Zhongshan, GuangdongAges 30–69 - 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+ - NCT06906016Recruiting
New blood tests for hepatitis B
This study looks at new blood tests (biomarkers) to better understand chronic hepatitis B and how it affects treatment decisions. It may help doctors find better ways to manage your condition.

Study of brain GABA signals in Dravet syndrome
This study looks at “GABA signals” in the body/brain to learn more about Dravet syndrome and how it may relate to seizures. If you have Dravet syndrome caused by a specific SCN1A gene change, you may be asked to provide genetic test results and help with study visits so researchers can compare biomarker readings.
Fort Worth, TexasAges Up to 18 years - NCT06574373Recruiting
Finding new markers for pancreatic IPMN progression
This study looks for new markers in the blood or tissues of people with a pancreatic condition called IPMN. The goal is to find better ways to predict if IPMN might turn into cancer and to help choose the best 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.
