MontpellierAges 18–99 - NCT06033183Recruiting
Study of radiation sensitivity in children with cancer
This study looks at how children's bodies respond to radiation therapy for certain cancers. By analyzing blood samples, researchers hope to learn why some children experience more side effects, which could help personalize future treatments.
CaenAges 3–18 - NCT06360302Recruiting
Exercise and insulin resistance in dialysis patients
This study looks at how exercise affects muscle metabolism and insulin resistance in people on dialysis, compared to those with metabolic syndrome and healthy individuals. It aims to find blood markers that could help assess insulin resistance in dialysis patients.
MontpellierAges 40–75 - NCT06603506Recruiting
Testing PARP inhibitors on your endometrial cancer cells
This study is testing whether a special kind of medicine called a PARP inhibitor can work against endometrial cancer cells grown in a lab from your tumor. The goal is to find out which patients might benefit from this treatment in the future.

Finding the best shock strength for atrial fibrillation treatment
This study compares different shock energy levels to find the most effective and safe way to reset an irregular heartbeat (atrial fibrillation) back to normal rhythm using a procedure called electrical cardioversion.
PragueAges 18 years+ - NCT06212921Recruiting
Biomarkers to predict acute mesenteric ischemia
This trial is looking for biomarkers (clues in your blood) that can help doctors predict acute mesenteric ischemia, a condition where blood flow to your gut is suddenly blocked. It may help find better ways to diagnose this serious condition early.
TartuAges 18 years+ - NCT06709209Recruiting
AI tool for grading colitis during colonoscopy
This study uses a special AI system that analyzes images from a colonoscopy to help doctors better understand how active your ulcerative colitis is and predict how it might progress. If you are scheduled for a routine colonoscopy, this AI tool may help your doctor make more precise treatment decisions.
LeuvenAges 18–75 - NCT07578597Enrolling by invitation
Pregnancy and Baby Health After Weight-Loss Surgery
This study compares how pregnancy and newborn health differ between women who had weight-loss surgery (gastric bypass or sleeve gastrectomy) and women who didn't. Researchers follow both mother and baby to understand potential risks and benefits.
OdenseAges 18 years+ - NCT05082961Recruiting
Blood immune markers and brain radiation after head/neck surgery
This study looks at immune system signals in your blood during and after postoperative radiation therapy for certain head and neck cancers involving the brain or skull base. Researchers want to see whether these “immune markers” relate to treatment response or side effects.
CaenAges 18 years+ - NCT07570524Recruiting
Predicting Treatment Response in Early Triple-Negative Breast Cancer
This study helps doctors predict which patients will respond best to immunochemotherapy (a combination of immune-boosting and chemotherapy drugs) for early-stage triple-negative breast cancer. By understanding your tumor better before treatment, doctors may be able to personalize your care plan.

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.
