Study of disease progression in women with X-linked adrenoleukodystrophy
This study follows women with a genetic condition called X-linked adrenoleukodystrophy (ALD) over time to see how the disease progresses. It includes annual check-ups and MRI scans of the brain and spinal cord to monitor changes.
ParisAges 18 years+ - NCT04375306Recruiting
Testing a heart-pressure ratio to choose bypass surgery plan
This trial studies whether a special heart “pressure/flow ratio” test (measured during the procedure) can help doctors choose the best plan for coronary bypass surgery. It may improve how bypass targets the problem blood vessels, but only if certain heart and health factors fit the study rules.
BonheidenAges 18 years+ - NCT05292651Recruiting
Stent placement strategy study for blocked heart arteries

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,548 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.
