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+ - NCT06807177Enrolling by invitation
Collagen injections for chronic neck pain
This trial tests if collagen injections into the neck can reduce chronic muscle pain and whether certain blood markers can show how well the treatment works. It may help if you have had neck pain for more than 12 weeks.
WarsawAges 18–65 - NCT05736146Recruiting

This study tests whether a simple, non-invasive procedure on your arm can change certain substances in your blood. It may help researchers understand how to protect the body from injury.
Xi'an, ShaanxiAges 18–45 - 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 - NCT05336851Recruiting
Emergency breathing test study for sudden lung infections
This trial tests an emergency breathing-related approach for adults with a sudden, community-acquired respiratory infection. It may help doctors quickly sort out what’s going on and guide early care.
Hong KongAges 18–100 - NCT05300997Recruiting
Test blood and antibody markers for suspected acute stroke
This study looks at blood tests to find signs of immune activity after a suspected stroke. It may help doctors diagnose stroke faster and better understand what is happening in the body soon after symptoms start.
Hong KongAges 18–100 - NCT05244408Recruiting
Blood test study for spinal cord injury recovery
This study looks at blood tests after a spinal cord injury to find markers that may predict recovery. The results could help doctors plan better treatment for future patients.
Vancouver, British ColumbiaAges 19 years+ - NCT04856059Recruiting
MRI study for early heart changes in Fabry disease
This study looks at early structural and tissue changes in the heart using a special type of MRI scan in adults with Fabry disease. It may help doctors understand changes earlier and better track heart involvement over time.
Toronto, OntarioAges 18 years+ - NCT03417856Enrolling by invitation
Study skin and blood signs in ichthyosis
This study looks at “skin and blood biomarkers,” meaning measurable signs in the body, in people with ichthyosis to better understand the condition. It may help researchers find ways to track disease activity and evaluate future treatments.
Chicago, IllinoisAges 1–60 - NCT07359742Recruiting
Detecting liver scarring in chronic liver disease
This trial looks for better ways to detect liver scarring (fibrosis) in people with long-term liver disease. It may help find problems earlier.
BrusselsAges 18 years+ - NCT05187819Recruiting
Blood test to help diagnose possible Alzheimer’s
This trial checks whether a simple blood test can help doctors diagnose Alzheimer’s in people who seem to have memory problems. If you’re being evaluated for possible dementia, your doctor may refer you to a memory clinic for testing and follow-up.
StavangerAges 40–100 - NCT03334708Recruiting
Blood test study for pancreatic cancer
This study looks at blood tests to find markers that may help detect and monitor pancreatic cancer. It compares people with pancreatic cancer to those with benign pancreatic conditions and healthy volunteers.
Middletown, New JerseyAges 18 years+ - NCT06305728Recruiting
New MRI scan and blood tests to find early signs of pancreatic cancer in people with IPMN
This study tests a special MRI scan and blood tests to see if they can detect early pancreatic cancer in people with high-risk pancreatic cysts called IPMNs. It may help identify cancer earlier, when treatment is more likely to work.
Basking Ridge, New JerseyAges 18 years+ - NCT06690684Enrolling by invitation
Finding new blood markers for heart disease
This study is looking for people who have had a heart attack or have heart failure to discover new markers in your blood that could help doctors better understand and treat heart disease. By collecting samples and health data, researchers hope to find clues that improve care for future patients.

Blood tests and thinking checks for memory clinic patients
This study is for people on a memory clinic waiting list. It uses a simple blood test and remote thinking exercises to help doctors understand memory problems better and improve care.
London, Greater LondonAges 50 years+ - NCT07666113Recruiting
Blood test for Alzheimer's disease detection in primary care
This study tests whether a simple blood test can help detect Alzheimer's disease in people who visit their primary care doctor with memory concerns. It aims to improve early diagnosis at the community level.
LeuvenAges 55–85 - NCT06380686Recruiting

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.
