This study looks at how common mild cognitive impairment and dementia are in people staying in rehabilitation units for heart, lung, or orthopedic problems. It aims to understand memory and thinking issues that may be overlooked in these settings.
Florence, FIAges 45 years+ - NCT07723339Enrolling by invitation
Exercise program for people aged 100 and older
This trial studies whether a supervised physical exercise program can improve the health and daily functioning of centenarians (people aged 100 or older). If you are at least 100 years old and can stand and move around with little help, this program might help you stay active and independent.
Pamplona, NavarreAges 100 years+ - NCT07707297Recruiting
Study of Navarre's Centenarians (born 1926-1927)
This study is for people aged 100 and older in Navarre, Spain. It aims to learn more about what contributes to a long and healthy life.
Pamplona, NavarreAges 100 years+ - NCT05385315Recruiting
Blood test study to help detect Parkinson’s disease early
This study looks for a new blood marker that could help doctors detect Parkinson’s disease earlier. Depending on your diagnosis and treatment status, your blood may be compared with other people’s to see how well the test works.
GrenobleAges 18 years+ - NCT07478016Recruiting
Studying inflammation and social factors in breast cancer
This study looks at how inflammation and social factors (like stress or support) affect breast cancer patients before they start treatment. You may qualify if you are a woman, newly diagnosed, and have not yet had any cancer treatment.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07447531Recruiting
MRI and blood test to track brain tumor changes
This study tests whether a special MRI scan and a blood test can help predict how a specific type of brain tumor (malignant glioma) changes over time. It is for people starting standard radiation and chemotherapy on a special machine that combines MRI and radiation.
Iowa City, IowaAges 21 years+ - NCT07404852Recruiting
Vagus nerve stimulation for reducing inflammation after stroke
This trial tests whether a non-invasive device that stimulates the vagus nerve can reduce inflammation and brain injury after a stroke caused by a large blood clot.
St Louis, MissouriAges 18–99 - NCT07373288Recruiting
HOXB7 and lung markers in pulmonary fibrosis
This study looks at a protein called HOXB7 and other markers in lung tissue and blood to better understand pulmonary fibrosis. It may help researchers find new ways to diagnose or treat the disease.
ModenaAges 18–80 - NCT07346118Recruiting
Guided fluid management in severe kidney failure using ultrasound
This study tests a new way to manage fluids in patients with acute kidney injury who are receiving a type of dialysis called continuous renal replacement therapy. The method uses ultrasound to check blood flow in the veins and kidneys to guide fluid decisions, which may help recovery.
BangkokAges 18 years+ - NCT07265323Recruiting
Testing insulin effects on brain function
This study looks at how giving insulin in a way that mimics the body's natural release can affect thinking and memory. It may help understand how insulin relates to brain health.

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.
