GrenobleAges 18 years+ - NCT05588115Recruiting
Test blood biomarkers to help diagnose concussion
This study checks whether a blood test can accurately and quickly identify an uncomplicated concussion. It may help doctors confirm concussion sooner and more reliably, and potentially reduce time and cost of diagnosis.
Calgary, AlbertaAges 18–65 - NCT05736146Recruiting
Testing Gulf War illness blood markers for better diagnosis
This study checks blood tests to see whether they can help confirm Gulf War illness. If you qualify as having Gulf War illness (or are a similar Gulf War veteran without it), your blood and health information may be used to validate these marker tests.
Palo Alto, CaliforniaAges 35 years+ - NCT06241807RecruitingPhase 2
Camrelizumab plus chemo before surgery for stage III lung cancer
This trial tests adding the immunotherapy drug camrelizumab to standard chemotherapy before surgery for people with stage IIIA-IIIB non-small cell lung cancer. The goal is to see if this combination shrinks tumors more effectively before removal.
Jinan, ShandongAges 18–75 - NCT06692400Recruiting
Suctioning, pain, and blood markers in intubated patients
This study looks at how routine suctioning of the breathing tube affects pain levels and certain substances in the blood in adults who are on a breathing machine for serious infections like flu, pneumonia, COVID, or sepsis. It may help doctors better understand and manage your comfort during this procedure.
Loma Linda, CaliforniaAges 18 years+ - NCT06599411Recruiting
Skin biomarkers for inflammatory disease treatment
This study looks for clues in your skin and blood that could predict how well you'll respond to treatments for conditions like eczema, psoriasis, or lupus. It aims to help doctors choose the best therapy for you.
ParisAges 18 years+ - NCT06610851Recruiting
Monitoring low-grade brain tumors with a blood test
This study is looking at whether a simple blood test that checks for tiny molecules (called miRNAs) can help monitor people with slow-growing brain tumors. If you had surgery for a grade 2 or 3 glioma at Caen University Hospital and are still being followed there, this study might be for you.
CaenAges 18 years+ - NCT06669546Recruiting
Quiet sounds during deep sleep for memory in older adults
This study tests whether playing a soft, silent sound (or no sound) during deep sleep can improve memory, brain activity, and blood markers. It is for older adults (60-85) who have mild memory issues but are otherwise healthy.
BernAges 60–85 - NCT06839300Recruiting
Blood biomarkers in spinal cord injury study
This study is looking for people with a spinal cord injury from a blunt force (not a penetrating injury like a gunshot or stab wound) to see if certain substances in the blood (called biomarkers) can help doctors understand the injury better and predict recovery. It involves an initial blood sample within 24 hours of the injury and follow-up assessments.
Milwaukee, WisconsinAges 19 years+ - NCT06925295RecruitingPhase 2
Xenon MRI to guide radiation for lung cancer
This trial tests whether a special MRI that uses xenon gas can help doctors better plan radiation therapy for lung cancer. You may join if you are scheduled for stereotactic body radiation therapy for your lung cancer.
Iowa City, IowaAges 18–80 - NCT07146412Recruiting
Lifestyle changes to lower dementia risk for older adults
This research study tests whether a program of healthy eating, exercise, and other lifestyle changes can lower your risk for dementia. It is designed for people aged 65–75 with a family history of dementia who want to take steps to keep their brain healthy.
Huntsville, AlabamaAges 65–75 - NCT07232667Recruiting

London, AlabamaAges 60 years+ - NCT07234695RecruitingPhase 3
Levetiracetam to prevent seizures in adults with Down syndrome and Alzheimer's

Common questions
- Are there clinical trials for biomarkers / blood?
- Yes. Clin2 currently lists 216 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.
