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+ - 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 - 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 - 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+ - 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+ - 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.

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 - 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 - 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+ - 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.
Créteil, CréteilAges 18 years+ - NCT04743674Recruiting
Blood and urine tests to track cervical cancer after treatment
This study tests whether DNA found in blood and urine can help detect cervical cancer and monitor it after treatment. If you’re newly diagnosed, these minimally invasive samples may help doctors follow your disease more easily over time.
Chapel Hill, North CarolinaAges 18 years+ - NCT05651204Recruiting
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 - NCT06259019Recruiting
Blood test during heart procedure to find disease markers
This trial uses a special device to take a small blood sample from your heart arteries during a planned procedure. It aims to find unique markers that could help doctors better understand and treat coronary artery disease.
BournemouthAges 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.
RomaAges 18 years+ - NCT04271397Recruiting
Testing immune blood markers in tuberculosis care
This study looks at immune system blood tests in adults being treated for active tuberculosis and/or latent tuberculosis infection. The goal is to see if these “immune biomarkers” can help guide or improve tuberculosis management.
LyonAges 18 years+ - NCT07411612Recruiting
Blood markers and confusion after surgery in older adults
This study looks at how inflammation and brain-related substances in the blood after surgery are linked to confusion (delirium) in older adults. It aims to find early warning signs to prevent this common complication.
ViennaAges 65 years+ - NCT07699094Recruiting
Predicting blood pressure changes in spinal cord injury
This study uses a simple finger sensor to monitor blood pressure regulation in people with spinal cord injury. It aims to find a new way to predict and manage blood pressure issues.
The Bronx, New YorkAges 18–75 - NCT06318949Recruiting
Albumin changes as early signs of chronic liver disease
This study is looking at whether changes in a protein called albumin can help find liver disease earlier. It is for people who have some liver scarring but no serious complications.
AngersAges 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+ - 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+ - NCT06451744Recruiting
Study of biomarkers in lichen planus
This study looks at people with lichen planus (a rash that can affect skin, mouth, or genitals) to find markers in cells and blood that may help understand the disease. If you have a new diagnosis or a flare-up, and you are not on strong immune-suppressing medicine, you may be able to join.
BesançonAges 18 years+ - NCT06846658Recruiting
Finding early signs of Parkinson's and related diseases
This study looks at cells from the nose, blood, and urine to find early markers for Parkinson's disease, similar conditions, and memory problems linked to Lewy bodies. If you have one of these conditions, joining could help improve early diagnosis.
Sesto Fiorentino, FIAges Any age - NCT06979765Recruiting
Blood tests for fatigue in low-platelet patients
This study looks for markers in the blood that are linked to fatigue in people with low platelets. It compares patients who have low platelets from immune or inherited causes to healthy volunteers, to understand why some feel very tired.
ParisAges 8 years+ - NCT06054854Recruiting
Lung Cancer Biomarker Study (BIRD Biobank)
This study collects blood, tissue, and other samples from people with lung nodules, suspected lung cancer, or confirmed lung cancer to find better ways to diagnose and treat the disease. By joining, you help researchers discover new biomarkers that could improve care for future patients.

Common questions
- Are there clinical trials for biomarkers / blood?
- Yes. Clin2 currently lists 217 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.
