San Francisco, CaliforniaAges 18 years+ - NCT02879071Recruiting
Follow-up after blocking abnormal brain blood vessels
This study checks people long-term after a procedure called embolization, which blocks abnormal blood vessel connections in the brain (arteriovenous malformations). It may help doctors learn how well the treatment lasts over time and what outcomes to expect.
ParisAges 18 years+ - NCT02878967Recruiting
Long-term follow-up after blocking a brain aneurysm
This study checks how patients do over the long term after a procedure called endovascular embolization that blocks blood flow to a brain aneurysm. It mainly helps doctors understand long-term safety and outcomes for this treatment.
ParisAges 18 years+ - NCT03830229Recruiting
Long-term follow-up for people with BAP1 mutations
This study follows people with a harmful (deleterious) BAP1 gene change to learn how it affects health over time. It may help researchers better understand mesothelioma risk and the long-term outcomes for families with this genetic mutation.
Bethesda, MarylandAges 2–120 - NCT03831958Recruiting
Follow-up study of children cured of Cushing disease
This study checks long-term health in people who were treated successfully for Cushing disease when they were under 21. It also collects information from family members to study genetic links to pituitary tumors.
Bethesda, MarylandAges 2–90 - NCT03772119Recruiting
Child surgery follow-up study for a spine bone shape issue
This study follows children aged 3–10 who need surgery for a specific type of spine bone shape problem (hemivertebra). It aims to track outcomes after the operation and how well follow-up is completed.
BordeauxAges 3–10 - NCT03610789Enrolling by invitation
Follow-up study for a specific hip implant system

Common questions
- Are there clinical trials for follow-up?
- Yes. Clin2 currently lists 592 recruiting follow-up 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 follow-up 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 follow-up 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.
