Blood test study to understand diabetic heart weakness
This study measures immune cells from your blood to find markers (biomarkers) that may explain or predict diabetic cardiomyopathy, a type of heart condition linked to diabetes. You may benefit mainly by being closely monitored and contributing to research that could improve future diagnosis or risk tracking.
BronAges 40–85 - NCT05714241Recruiting
Blood tests to study heart pain with blocked-unblocked arteries
This study looks at blood “biomarkers” and platelet function to better understand INOCA (heart-related chest pain despite no major artery blockage). You may be eligible if you have INOCA and are already taking aspirin, and if you haven’t taken certain blood-thinner or platelet-altering medicines recently.
RomeAges 18 years+ - NCT06967532Recruiting
Using a virus to predict how well lung cancer treatment works
This study checks if a common virus (Torque Teno virus) can help predict how well immune checkpoint inhibitor therapy works for non-small cell lung cancer (NSCLC) and what happens after surgery. The goal is to find a better way to match treatment to patients.
ViennaAges 18 years+ - NCT07049588Recruiting
Finding early signs of Charcot-Marie-Tooth 1A
This trial looks for new markers of Charcot-Marie-Tooth 1A (CMT1A) early in the disease. Researchers hope to find signs that can help diagnose and track the disease better, which could lead to better treatments in the future.
MarseilleAges 10–30 - NCT00823654Recruiting
Blood tests during treatment to track ovarian egg supply
This study measures blood biomarkers to understand how breast cancer treatment affects a person’s future fertility (ovarian reserve). It may help patients learn more about egg supply changes after chemotherapy and hormone-related treatments.
Basking Ridge, New JerseyAges 18–44 - NCT06016569Recruiting
Breath test for early lung cancer in high-risk smokers
This study tests a new breath test to find early signs of lung cancer in people at high risk. It looks for cancer biomarkers in the air you breathe out. If you are a heavy smoker between 55 and 74, this trial may help detect lung cancer earlier.
BrnoAges 55–74 - NCT03207854Recruiting
Donate blood and immune samples for cancer, blood, or healthy volunteers study
This study collects blood and immune-related samples from people with cancer, certain immune-related blood conditions, or healthy volunteers. It helps researchers understand immune changes and may support future diagnosis or treatments.
Los Angeles, CaliforniaAges 19 years+ - NCT07707245Recruiting
Finding biomarkers in lung disease and lung cancer
This trial studies blood and tissue samples from people with COPD, IPF, or lung cancer to find markers that can help diagnose and predict these conditions. It aims to discover why some lung diseases progress to cancer.

Can blood tests improve lung cancer screening in smokers with artery disease?
This study looks at whether certain blood tests can help find lung cancer early in people who have smoked for a long time and also have artery disease. The goal is to see if adding these tests to current screening methods can better identify those at highest risk.

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.
