Genomic testing for cancer of unknown primary
This trial is for people with cancer of unknown primary (CUP), meaning cancer that started in an unknown place in the body. It aims to use advanced genomic testing (looking at your tumor's DNA) on your stored tumor sample and blood to find clues about where the cancer began and possible treatment options.
Manchester, Greater ManchesterAges 16 years+ - NCT06692751Recruiting
Eye scan for microvascular angina
This study tests if a non-invasive eye scan (OCT-A) can detect changes in tiny blood vessels in the retina of people with chest pain caused by problems with the heart's small arteries (microvascular angina). If it works, it could be a simpler way to diagnose this condition.
DijonAges 18 years+ - NCT06636318Recruiting
Immune changes during 24-hour surgery call

Common questions
- Are there clinical trials studying Blood sampling?
- Yes. Clin2 currently lists 684 recruiting studies that include Blood sampling, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Blood sampling trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Blood sampling an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Blood sampling or a specific trial is right for you.
