This study uses a special PET/CT brain scan to look at a protein called tau in people with memory/thinking and movement disorders. The results may help researchers understand how these diseases affect the brain and improve future diagnosis or care.
Philadelphia, PennsylvaniaAges 18–100 - NCT06122415Recruiting
Memory clinic study with fluid and cognitive tests
This study looks at people who are being checked for memory or thinking problems. It uses standard tests done at the memory clinic, like a spinal tap and blood draw, plus memory and thinking tests, to learn more about these symptoms. You can join if these tests are already planned as part of your regular care, even if you don't take part in the study.
MalmöAges Any age - NCT06104397Enrolling by invitation

Chicago, IllinoisAges 18–89 - NCT06120361Recruiting
Primary care study for early cognitive decline
This research study looks at people who have noticed problems with memory or thinking (like trouble focusing or finding words) and visit their primary care doctor for help. It aims to better understand and diagnose conditions that cause these symptoms, such as Alzheimer's disease.
MalmöAges 40 years+ - NCT06114667Recruiting
Nasal high flow vs. mask for COPD flare-up
This study compares two types of breathing support for people having a severe COPD flare-up with high carbon dioxide and acidic blood. It tests if a gentle air flow through the nose (nasal high flow) works as well as a mask (non-invasive ventilation) to help you breathe better.
Montpellier, MontepllierAges 18–85 - NCT04775537Recruiting
OssiMend bone graft for lumbar spine fusion surgery
This trial studies whether OssiMend bone graft helps heal a lumbar spine fusion for people whose disc disease has not improved with non-surgical care. It may be an option if you need back surgery due to specific spine wear-and-tear changes.
Encinitas, CaliforniaAges 18 years+ - NCT05866302Recruiting
CT breathing-scan test to detect chronic lung injury after transplant
This study uses a special way to analyze breathing-related CT images to find early or ongoing lung injury after an allogeneic stem cell transplant. It may help clinicians recognize chronic lung complications sooner and better guide care.
Stanford, CaliforniaAges 3 years+ - NCT04099992Recruiting
Mindfulness program for people with chronic kidney disease
This trial tests whether a mindfulness-based program can help people living with moderate-to-advanced kidney disease. It may improve how you feel day-to-day and how you manage symptoms, while researchers track kidney-related health and safety.
Atlanta, GeorgiaAges 40–80 - NCT05928936RecruitingPhase 2
Exercise study in chronic kidney disease with blood-pressure medicines
This study tests how the body’s blood-pressure control responds to exercise in people with chronic kidney disease (and some transplant recipients), compared with people without kidney disease. It may help researchers learn safer ways to exercise and manage blood pressure for people with kidney disease.
Atlanta, GeorgiaAges 40–75 - NCT03364803Recruiting
Sharing treatment results for people with Cushing’s syndrome
This is a study that collects and reviews information about how people with Cushing’s syndrome (including some mild forms and certain “silent” tumors) are diagnosed and treated, and what outcomes they have. It may help researchers understand which treatments work best in different types of the condition.
Basking Ridge, New JerseyAges 14 years+ - NCT06088355Recruiting
Comparing exercise amounts for moderate Parkinson's
This study compares two different amounts of light-to-moderate exercise to see which is better for people with moderate Parkinson's disease. It involves walking or doing similar activities at a comfortable pace, either a moderate amount or a higher volume, over several weeks.
Decatur, GeorgiaAges 40 years+ - NCT06084091Recruiting
Measuring heart oxygen levels during open-heart surgery
This study measures oxygen levels in the heart muscle during open-heart surgery using a light-based technique. You may qualify if you are an adult scheduled for this surgery and can provide consent.
Helsinki, UusimaaAges 18–90 - NCT06092034RecruitingPhase 2
Gene therapy for Danon disease in males
This trial tests a gene therapy called RP-A501 for males with Danon disease, a genetic condition that affects the heart. The treatment aims to fix the faulty gene to help improve heart function and slow disease progression.
La Jolla, CaliforniaAges 8 years+ - NCT06100289RecruitingPhase 3
Study of vedolizumab for kids with ulcerative colitis or Crohn's disease
This trial tests vedolizumab, a biologic medicine that reduces inflammation, in children and teenagers who have moderate to severe ulcerative colitis or Crohn's disease and have not responded well to other treatments.
Phoenix, ArizonaAges 2–17 - NCT06081439Recruiting
Immune markers and mental fatigue in Graves' disease
This study looks at whether certain immune system markers are linked to mental fatigue (feeling tired or foggy in the mind) in people with newly diagnosed Graves' disease. If you join, you'll help researchers understand how your immune system might affect your energy and thinking.
GothenburgAges 18–72 - NCT05733832Recruiting
Transitional care after hospital discharge for serious liver disease
This trial tests an extra support program after you leave the hospital to help people with advanced liver disease avoid complications and stay on track. It may help by providing structured follow-up soon after discharge.
Chicago, IllinoisAges 18 years+ - NCT06094192Recruiting
Brain stimulation to improve memory in Alzheimer's
This study tests whether a gentle, noninvasive brain stimulation technique called tACS can help improve memory in people with Alzheimer's disease or mild cognitive impairment. It may also include healthy older adults for comparison.
Boston, MassachusettsAges 50–100 - NCT06104228RecruitingPhase 2

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,612 recruiting general population (no specific condition or disease) 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 general population (no specific condition or disease) 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 general population (no specific condition or disease) 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.
