Risk of Eye Bulge in Highly Myopic Europeans
This study looks at the risk of a back-of-the-eye bulge (posterior staphyloma) in people with high myopia. It uses existing eye images to understand the anatomy of highly myopic eyes.

BesançonAges 18 years+ - NCT06324149Recruiting
Frailty and aging conditions in chronic diseases
This study looks at how frailty affects the course of chronic diseases and how chronic diseases affect frailty. It may help understand aging-related conditions better.
MilanAges 18–100 - NCT06904625Recruiting
Capturing tumor cells in metastatic breast or prostate cancer
This study compares different methods of capturing circulating tumor cells (CTCs) from blood samples in patients with metastatic breast or prostate cancer. It aims to improve how we detect and monitor cancer cells that have spread, which could help guide future treatment decisions.
ToulouseAges 18 years+ - NCT06894654Recruiting
Identifying skin regulation in scleroderma
This study compares skin samples from people with scleroderma and healthy volunteers to understand what goes wrong in the skin. It may help researchers find new treatment targets.
LeedsAges 18 years+ - NCT06718127Recruiting
Study of immune response to yellow fever vaccine
This study looks at how your body's immune system responds to the yellow fever vaccine. It may help researchers understand how well the vaccine protects people.
ParisAges 18–65 - NCT06889844Recruiting
Blood test for colorectal cancer cross-reactivity study
This research study uses a blood test to look for signs of colorectal cancer in people who have other types of cancer or digestive diseases. The goal is to see if the test can correctly tell the difference between colorectal cancer and other conditions.
Málaga, AndalusiaAges 18 years+ - NCT06451744Recruiting
Study of biomarkers in lichen planus
This study looks at people with lichen planus (a rash that can affect skin, mouth, or genitals) to find markers in cells and blood that may help understand the disease. If you have a new diagnosis or a flare-up, and you are not on strong immune-suppressing medicine, you may be able to join.
BesançonAges 18 years+ - NCT06869564Recruiting
Blood test study for acute mesenteric ischemia diagnosis
This pilot study looks at markers in your blood that might help doctors tell if you have a serious bowel condition called acute mesenteric ischemia. You may be asked to participate if you have severe belly pain and need a special CT scan to check for this condition.
MarseilleAges 18 years+ - NCT06864481Recruiting
Study of liver inflammation from immunotherapy drugs
This study follows people who develop liver inflammation (hepatitis) after starting immunotherapy for cancer. It helps doctors understand how often this happens and how to manage it.
MontpellierAges 18 years+ - NCT06851975Recruiting
Blood tests to learn about cancer and treatment
This study collects extra blood samples during your routine care to look for markers that might help predict how well cancer treatments work and how long people live. Participating involves no extra procedures beyond what you already need.

Common questions
- Are there clinical trials studying Blood samples?
- Yes. Clin2 currently lists 684 recruiting studies that include Blood samples, 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 samples 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 samples 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 samples or a specific trial is right for you.
