Study uses donor cord blood to restore blood cell production
This study tests giving you donated umbilical cord blood through an IV to help your body rebuild blood-forming cells after chemotherapy. It may help people who need a stem-cell “reset” using a specific type of cord blood unit that meets strict matching and safety rules.
Minneapolis, MinnesotaAges Any age - NCT02007356RecruitingPhase 2
Donor immune cell infusions for viral infections after stem cell transplant
This trial studies whether directly infusing donor-made immune cells (virus-fighting T-cells) is safe and feasible in people who still have viral infections after a stem cell transplant. It may help your body control infections from adenovirus, CMV, or EBV when standard antiviral treatments aren’t working.
BaselAges 18–65 - NCT01372800Recruiting
Study blood adiponectin levels and stroke/heart risk
This study measures a blood marker called adiponectin and looks at how it relates to heart and stroke (cardiovascular and cerebrovascular) problems over time. It may help doctors understand who is at higher risk, especially in Chinese participants.
Xi'an, ShaanxiAges 18–85 - NCT00920972RecruitingPhase 1/Phase 2
Bone marrow transplant prep for children with non-cancer blood disorders
This early-stage study tests a specific chemotherapy “conditioning” regimen to prepare the body for a bone marrow transplant in children with certain non-cancer blood or immune conditions. It may help the transplant work better, but it also carries risks from the chemotherapy and transplant process.
Phoenix, ArizonaAges Up to 20 years - NCT02670031Recruiting
Blood pressure study using heart MRI in adults
This study looks at how the heart muscle reacts in people with high blood pressure. You may have heart imaging (MRI) and blood pressure monitoring to understand patterns and potential ways to help.
SingaporeAges 21–99 - NCT02918188RecruitingPhase 2
Hydrogen therapy for steroid-resistant graft-versus-host disease
This Phase 2 study tests whether hydrogen therapy can improve symptoms in people with chronic graft-versus-host disease (cGVHD) who cannot tolerate steroid treatment. If steroids aren’t working or can’t be used, this trial may offer an alternative approach to help control the illness.
Beijing, Beijing MunicipalityAges Up to 65 years - NCT03352193Recruiting
Oral wheat tolerance treatment for children with wheat allergy
This trial tests a supervised “oral tolerance induction” approach, which means giving carefully controlled wheat exposure to try to train the immune system to tolerate wheat. It’s designed for children who have confirmed IgE-mediated wheat allergy, aiming to reduce allergic reactions over time.
AthensAges 2–16 - NCT02202681Enrolling by invitation
Swallowable capsule scans the duodenum with special imaging
This study tests whether a swallowable imaging capsule can safely look at the duodenum (the first part of the small intestine). It may help researchers better understand gut lining changes, such as those seen in celiac disease.
Boston, MassachusettsAges 16 years+ - NCT00950430Enrolling by invitationPhase 4
Brain scan study for amyloid plaques in adults
This study uses brain imaging to look for amyloid plaques (abnormal protein deposits) as people age. It may help researchers better understand how these changes develop over time.
Rochester, MinnesotaAges 30–100 - NCT07401680RecruitingPhase 1
Stool transplant for active ulcerative colitis
This trial tests whether a stool transplant (fecal microbiota transplantation) can help manage active ulcerative colitis. You would receive a transplant from a healthy donor to see if it improves your symptoms.

Vagus nerve stimulation for thinking skills in health and Parkinson's
This study explores whether vagus nerve stimulation (a gentle electrical pulse that travels through a nerve in your ear) can boost thinking and decision-making skills in healthy people and those with Parkinson's disease. It involves a noninvasive device that stimulates the ear, and you may participate if you meet certain health criteria.
Aurora, ColoradoAges 18–65 - NCT07425821RecruitingPhase 1

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,739 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.
