Sarasota, FloridaAges 18–89 - NCT06809725Enrolling by invitation
Study of a headband device for cognitive health check
This study tests a new way to check cognitive (thinking and memory) health using a simple headband that measures electrical signals on your scalp. It is looking for people 65 to 90 years old, with or without memory concerns, and a family member or friend who can also take part.
Miami, FloridaAges 65–90 - NCT06603259Enrolling by invitation
Galleri test follow-up study
This study looks at the Galleri test, a blood test that checks for early signs of cancer. If you already had the Galleri test as part of your regular care, this study will collect some information from your medical records to learn more about how the test works in the real world.
Menlo Park, CaliforniaAges Any age - NCT06595615Enrolling by invitation
Heart health app data collection study
This trial gathers health data from a smartphone app to learn more about heart failure in people with a specific type of implanted heart device. The information will help doctors better understand how to treat and manage heart failure.
Huntsville, AlabamaAges 18 years+ - NCT06215105Enrolling by invitation
Collecting real-world data on treatments for brain aneurysms
This trial is gathering information from patients who are getting a standard treatment for a brain aneurysm using MicroVention devices. It helps doctors understand how well these treatments work in real life.
Hollywood, FloridaAges Any age - NCT04682145Enrolling by invitation
Uses EUHASS data to study turoctocog alfa pegol side effects
This study collects and reviews side-effect information from the EUHASS registry in people with hemophilia. It may help doctors better understand how turoctocog alfa pegol (a clotting medicine) is tolerated in real-world care.
SøborgAges Any age - NCT04450927Enrolling by invitation
Collecting health data from NHLBI patients and donors
This study collects information about standard care for people seen by the NHLBI, and also about donors. It helps researchers understand what happens in real-world care, which can improve future treatment decisions.
Bethesda, MarylandAges 2–120 - NCT03690336Enrolling by invitation
Using registry records to study nonacog beta pegol safety
This study looks at safety information using existing patient registry records, not new treatment visits. It may help researchers better understand side effects of nonacog beta pegol by using real-world data.
BaarnAges Any age - NCT02478892Recruiting
Screening study for pancreatic cancer in inherited gene risk
This trial tests ways to screen people who have a family-passed (inherited) gene mutation linked to higher pancreatic cancer risk. The goal is to find pancreatic cancer earlier and improve how screening is done for people at increased risk.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05555693Recruiting
Brain chemistry study after surgery in older adults
This study looks at how brain “metabolomics” (small chemical signals in the brain/body) relate to thinking or mood problems that can happen after surgery in people age 65 and older. It may help doctors understand who is more likely to have these side effects after an operation.

Common questions
- Are there clinical trials for data collection?
- Yes. Clin2 currently lists 338 recruiting data collection 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 data collection 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 data collection 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.
