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+ - 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+ - 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.
ToulouseAges 18 years+ - NCT07772570Recruiting
Studying blood markers in coronary artery disease
This study collects blood samples and images from patients with heart muscle damage or those undergoing coronary angiography. The goal is to find new biomarkers that could improve diagnosis and treatment of coronary artery disease.
OxfordAges 18–90 - NCT02381301Recruiting
Blood and heart CT scan tests for heart blood-flow markers
This study looks at whether certain lab “biomarkers” and a heart CT scan can help understand heart blood flow in people getting routine coronary CT angiography (CCTA). It may be useful for improving how doctors assess heart health from scan and blood results.
Maastricht, LimburgAges 18 years+ - NCT06058182Recruiting
Rna biomarkers for heart attack patients
This study looks at RNA markers in the blood of people having their first heart attack to see if they can predict recovery. If you are scheduled for a procedure to open blocked arteries, you may be able to join.
Milan, MilanAges 18 years+ - NCT06212921Recruiting
Biomarkers to predict acute mesenteric ischemia
This trial is looking for biomarkers (clues in your blood) that can help doctors predict acute mesenteric ischemia, a condition where blood flow to your gut is suddenly blocked. It may help find better ways to diagnose this serious condition early.
TartuAges 18 years+ - NCT07444736Enrolling by invitation
Exercise with blood flow restriction for adults with obesity
This study tests if adding blood flow restriction to resistance training can improve muscle strength and health in adults with obesity. It may help you build muscle more efficiently with lighter weights.
Tlajomulco de Zúñiga, JaliscoAges 18–30 - NCT05534347Recruiting
Blood marker study in teens with juvenile arthritis
This study looks at blood (and related) markers that may reflect inflammation in people with juvenile idiopathic arthritis. It may help doctors better understand disease activity and guide future care for patients who are able to join.
Paris, IDFAges 16 years+ - NCT03419689Recruiting
Study checks blood and tumor markers in advanced ovarian cancer
This study looks at “biomarkers,” meaning measurable signals in blood and tumor tissue, in people with advanced ovarian-type cancers. The goal is to understand these markers and how they relate to the cancer, which may help guide future care.
Barrie, OntarioAges 18 years+ - NCT03420118Recruiting
Study of tumor and blood markers in gynecologic cancers
This study looks at tumor tissue and blood samples to find biological “markers” in people with gynecologic cancers. It may help researchers understand disease better and could guide future, more personalized treatments.
Toronto, OntarioAges 18 years+ - NCT03518099Recruiting
Testing blood signals after sudden bowel blood flow injury
This study is looking for signs in the body (called biomarkers) after sudden loss of blood flow to the intestines. It involves getting a CT scan to check what is happening in the abdomen so the researchers can see which signals match intestinal injury.
ClichyAges 18 years+ - NCT07685405Recruiting
Biomarker study for Ewing sarcoma
This study looks for special markers called 'biomarkers' in the blood of people with Ewing sarcoma and compares them to people without cancer. It aims to find new ways to understand and potentially monitor this tumor using tiny particles in the blood.
Bologna, BOAges Any age - NCT06810258Recruiting
Biomarkers before and after kidney transplant
This study will collect blood samples from people having a kidney biopsy or a kidney transplant to look for biomarkers (biological signs) that can give doctors more information about kidney health. Participating may help doctors better understand and treat kidney disease in the future.
CréteilAges 18 years+ - NCT07201363Recruiting
Inflammation and scarring markers after TAVI
This study looks at markers of inflammation and scarring in people who develop heart rhythm problems after having a TAVI procedure (a minimally invasive valve replacement). It may help doctors understand and predict these complications.
Rijeka, CroatiaAges 18 years+ - NCT05769699Recruiting

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.
