Baltimore, MarylandAges 18–60 - NCT07700186Recruiting
Skin barrier health in women who use UV nail lamps
This study looks at whether UV nail lamps affect the skin barrier on your hands. By filling out a questionnaire and having your skin checked, you can help researchers understand if these lamps are safe.
SplitAges 18–50 - NCT04216342RecruitingPhase 1
Testing a new breathing-drug ingredient in healthy adults
This early study (Phase 1) tests how safe and tolerable Fx-5A is, and how the body processes it, in healthy volunteers. It’s mainly looking to understand side effects and drug levels rather than treating a disease.
Bethesda, MarylandAges 18–99 - NCT03076658Recruiting
Standing full-body X-rays from healthy adults
This trial is building a database of full-body standing X-rays in people who do not have spine problems or certain health conditions. If you qualify, your X-rays may help researchers study normal body alignment for future medical use.
Aurora, ColoradoAges 21–85 - NCT03182400Recruiting
Brain and sense testing in healthy kids and adults
This study measures how your brain processes sounds, touch, and thinking tasks in healthy people. It mainly helps researchers understand normal sensory and thinking function, which can guide future studies and tests.
ToursAges 1–60 - NCT03207854Recruiting
Donate blood and immune samples for cancer, blood, or healthy volunteers study
This study collects blood and immune-related samples from people with cancer, certain immune-related blood conditions, or healthy volunteers. It helps researchers understand immune changes and may support future diagnosis or treatments.
Los Angeles, CaliforniaAges 19 years+ - NCT03223090Recruiting
Motor language learning study for French speakers
This study tests how people learn language using brain-and-movement training (including tasks during brain scans and non-drug brain stimulation for some parts). It may help researchers understand learning and how the brain adapts during new language practice.
BronAges 20–40 - NCT03258580Recruiting
Studying how culture and mind affect how we feel pain
This study looks at how beliefs, mood, and social factors affect how people express and judge pain. It mainly uses pain/heat testing and—if chosen—brain scans to understand why pain reports can differ between people.

Common questions
- Are there clinical trials for volunteers?
- Yes. Clin2 currently lists 526 recruiting volunteers 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 volunteers 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 volunteers 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.
