Study of brain calcium deposits on CT scans
This study looks at people who have extra calcium deposits in the brain seen on a CT scan (and also includes some relatives and healthy volunteers). It aims to better understand who has brain calcification and what it may mean, using research visits and scan-based measurements.
Fuzhou, FujianAges Any age - NCT04369209Recruiting
Study of people with FSHD1 gene changes
This is a study that follows people who have a confirmed FSHD1 genetic change (and some healthy people for comparison). It may help researchers better understand the condition and how it affects people over time.
Fuzhou, FujianAges Any age - NCT03919305Recruiting
Study of blood clots in brain veins
This study follows people who have a blood clot in the brain’s venous drainage system. It aims to better understand this condition and may help improve how it is recognized and managed.
BeijingAges Any age - NCT04220905Recruiting
Watching outcomes after removing large colon and duodenal polyps
This observational study follows people who have large polyps in the colon or duodenum that are removed during endoscopy. It aims to understand how safe and effective this approach is, and what outcomes patients have afterward.
White River Junction, VermontAges 18 years+ - NCT01747291Recruiting
Study of incomplete atypical bone fractures
This study follows people who have had a specific type of bone injury called an atypical fracture, or a similar fracture after little or no trauma. It aims to better understand who is affected and how these injuries behave over time.
Hamilton, OntarioAges 20–100 - NCT07174141Recruiting
Heart risks from newer blood cancer drugs (acalabrutinib or zanubrutinib)
This study looks for early signs of heart problems in people taking newer targeted blood cancer drugs called acalabrutinib or zanubrutinib. By using special blood tests, doctors hope to catch and manage heart issues before they become serious.
DijonAges 18 years+ - NCT06475196Enrolling by invitation

Study of vaginal and uterine microbiome after frozen embryo transfer
This study looks at how bacteria in the vagina and lining of the uterus change during the “luteal phase” (the time after ovulation and before a pregnancy test) in people using frozen embryo transfers. It may help researchers understand what conditions support embryo implantation and pregnancy in assisted reproduction.
Saarbrücken, SaarlandAges 18–45 - NCT03650673Recruiting

Common questions
- Are there clinical trials for cohort studies?
- Yes. Clin2 currently lists 569 recruiting cohort studies 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 cohort studies 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 cohort studies 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.
