Brain waves and thinking in Parkinson's disease
This study looks at how brain activity relates to thinking and memory in people with Parkinson's disease, including those with and without cognitive issues, and those with deep brain stimulation. It uses EEG (a non-invasive brain wave recording) and sometimes mild brain stimulation (TMS or tACS) to understand these connections better.

Brain stimulation for Parkinson's motor symptoms
This study tests a new type of brain stimulation (STN-tTIS) to see if it helps improve movement symptoms in people with Parkinson's. The study compares how the stimulation works when you are taking your regular medications and when you are not.

Light-based muscle oxygen measurements in COPD with kidney disease
This study uses a special light-based device (near-infrared spectroscopy) to measure muscle oxygen levels in people who have both COPD and chronic kidney disease. Researchers want to see if these measurements can help predict how the disease progresses, which could lead to better monitoring and treatment.

AI ECG for detecting low heart pumping in older adults
This trial uses an AI tool to analyze your ECG (heart tracing) to detect low pumping function. It may help find hidden heart issues early, especially if you haven't had a recent heart ultrasound.
TaipeiAges 60–85 - NCT06958640Enrolling by invitation
Da Qing offspring health study
This study looks at the health of children, grandchildren, and great-grandchildren of people who took part in a diabetes prevention study in Daqing, China. It aims to understand how their family history affects their health over time.
Beijing, Beijing MunicipalityAges Any age - NCT06954792Enrolling by invitation
Studying heart changes after tricuspid valve replacement
This study looks at how the heart adjusts after a procedure to replace the tricuspid valve (the valve between the right upper and lower heart chambers). It focuses on patients who need medication to support their blood pressure within 24 hours after the procedure, to better understand and manage this unstable period.
New York, New YorkAges 18 years+ - NCT06950931Enrolling by invitation
Urine test for kidney problem after transplant or biopsy

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,742 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.
