Online testing study to prevent or spot Alzheimer’s early
This study invites people age 50+ who do not have dementia to do ongoing thinking tests online. If an online risk screen suggests you may be at higher risk, you may be referred for in-person body tests (biomarker assessment).
San Diego, CaliforniaAges 50–85 - NCT03643718Recruiting
Emergency surgery and trauma patient registry online
This trial is a web-based registry that collects information about people who need emergency surgical or non-surgical treatment for sudden (acute) problems. Your information can help doctors better understand and improve emergency care and decision-making.
PisaAges Any age - NCT03665831Recruiting
Deep TMS for depression and memory problems in older adults
This study tests a type of brain stimulation called Deep TMS to help reduce depression and improve or stabilize memory-related symptoms in older adults with Alzheimer’s disease. It’s mainly for people whose depression did not improve or could not be tolerated with antidepressant medicine.

Heart valve patients getting a catheter procedure
This is a registry that follows people who are having a catheter-based treatment for a heart valve problem. It helps doctors understand how these procedures work in real life and may improve future care.
LeuvenAges Any age - NCT03676504RecruitingPhase 1/Phase 2
CAR T cell therapy for relapsed CD19 blood cancers
This trial tests a type of personalized immune treatment (CD19 CAR T cells made from your T cells) for adults (and children with ALL) whose CD19-positive blood cancer has come back or didn’t respond. It may help your immune system recognize and attack cancer cells that still have CD19.
HeidelbergAges 3 years+ - NCT03702907Recruiting
Study of aging and a brain sample bank
This study follows adults as they age and may collect biological samples for future research. It could help researchers understand early and late changes related to aging and brain health.
Washington D.C., District of ColumbiaAges 45 years+ - NCT03713268Recruiting
Using a scan to guide eye surgery in real time
This trial tests whether a special eye scan (OCT) can help guide eye surgery during the operation. It may improve how surgeons see and target the exact eye structures they need to treat.
Durham, North CarolinaAges 4 weeks+ - NCT03716908Recruiting
Study of hearing gene changes in DFNA9 family members
This study looks at how a specific inherited gene change (the P51S COCH mutation) connects to hearing and balance symptoms over time. It may help researchers better predict who will develop symptoms and how they may progress.
AntwerpAges 18 years+ - NCT03718403RecruitingPhase 4
Theophylline trial for pseudohypoparathyroidism
This Phase 4 study tests whether the medicine theophylline can help people with pseudohypoparathyroidism type 1A or 1B. It may be considered if you’re trying to improve how your body uses parathyroid hormone and manage related calcium levels.
Boston, MassachusettsAges 5–21 - NCT03735992Recruiting
Mind-body sessions for people with blood cancers in remission
This trial studies whether structured mind-body group sessions can support well-being and recovery for people whose blood cancer is in remission. It may be helpful if you can safely participate in group activities and are not currently receiving active cancer treatments.
StuttgartAges 18 years+ - NCT03740256RecruitingPhase 1
HER2-targeted oncolytic virus plus custom immune cells for solid cancers
This Phase 1 study tests a treatment plan that combines a virus designed to attack cancer with your own custom immune cells that target HER2. It aims to shrink advanced HER2-positive solid tumors (and make future options safer/more effective).
Houston, TexasAges 18 years+ - NCT03746535RecruitingEarly Phase 1
Study heart disease risk in women with endometriosis
This early study looks at how endometriosis may affect heart and blood-vessel risk in women aged 18 to 45. It may help doctors understand risks better and plan safer prevention and monitoring for people with endometriosis.
New Haven, ConnecticutAges 18–45 - NCT03749980Recruiting
Study following people with von Hippel-Lindau (VHL)
This study follows people who have von Hippel-Lindau (VHL) over time to better understand how the condition changes. It may help doctors plan future treatments by collecting long-term health information.
Boston, MassachusettsAges Any age - NCT03753555RecruitingPhase 4
High-intensity statin treatment for certain stroke artery plaque cases
This trial tests whether a higher-dose statin can help after an ischemic stroke in people who have specific plaque patterns in brain blood vessels. It may help lower the risk of another stroke by targeting the artery plaque process.
ShenyangAges 18–80 - NCT03761381Recruiting
Eye scan study for mild Alzheimer’s and memory changes
This study uses detailed eye imaging (an eye scan) to look for signs related to probable Alzheimer’s disease and mild dementia. It may help researchers understand whether eye scans can reflect brain changes and improve detection.
Portland, OregonAges 55 years+ - NCT03775954Recruiting
Fetal heart testing in high-risk pregnancies after baby loss
This study checks unborn babies’ heart signals using special scans during pregnancy and then checks the baby’s heart shortly after birth. It may help researchers understand why certain high-risk pregnancies can lead to fetal demise and improve care.

- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 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.
