Recruiting studies
- NCT06585917Enrolling by invitation
Comparing two sheath sizes for wrist artery heart procedures
This trial compares two sizes of small tubes (called sheaths) used during a heart procedure to open blocked arteries. The procedure is done through a tiny artery in your wrist, and the goal is to see if a smaller tube works just as well with fewer side effects.

Diet and belly fat study for overweight adults
This study tests how different diets affect belly fat, thigh muscle, and heart health in people who are overweight. It might help you find a way to eat that improves your health.
Recife, PernambucoAges 20 years+ - NCT06293924Enrolling by invitation
Testing fluid around the heart in recurring pericarditis
This study analyzes pericardial fluid (the fluid around your heart) to understand why pericarditis comes back. If you have pericarditis or other heart fluid buildup requiring drainage, or if you're having heart surgery, you may be able to participate.

Long-term follow-up of sensory stimulation for Alzheimer's
This is a follow-up study for people who already completed the 12-month Hope Study (CA-0011). It tests long-term safety and effects of a gentle sensory stimulation device (light and sound) for Alzheimer's disease. You will continue using the device at home with a study partner.

Common questions
- 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.
