Exercise program for people with Parkinson's and a deep brain stimulator
This study tests whether a structured physical activity program can improve movement and quality of life for people with Parkinson's who have a deep brain stimulator (DBS) device. Half the participants will do the exercise program, and half will continue usual care, to see if exercise helps manage symptoms.
WarsawAges 50–70 - NCT07840547Recruiting
Remote check-ins for Creutzfeldt-Jakob disease
This study uses video calls to check on people with Creutzfeldt-Jakob disease (a rare brain disorder) and their care partners. It aims to understand how the disease progresses and improve support.
Cleveland, OhioAges 18 years+ - NCT06459934Recruiting
Heart and cardiovascular disease study
This study looks at the health outcomes of people with common heart conditions like coronary artery disease, high blood pressure, heart failure, or cardiomyopathy. It may help researchers understand how these conditions progress and how to better manage them.

Kissimmee, FloridaAges 18–85 - NCT06141525Recruiting
Remote conditioning for safer heart bypass recovery
This study tests whether a simple, non-invasive treatment called remote ischemic conditioning (using a blood pressure cuff on your arm) can help patients recover better after off-pump heart bypass surgery. The goal is to see if it reduces complications and improves heart function.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,559 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.
