Searching for new markers in age-related eye diseases
This study looks for proteins in the blood and eye fluids that may help doctors better understand and monitor three common eye conditions: age-related macular degeneration, diabetic retinopathy, and retinal detachment. If you have one of these conditions, or if you are a healthy control with no retinal disease, you may be able to help by giving a small sample of blood or fluid from your eye during a routine procedure.

Family eating habits and chronic inflammation study
This study looks at how eating habits and family health history relate to chronic inflammatory conditions like Crohn's disease, ulcerative colitis, and juvenile idiopathic arthritis. It aims to understand these links by studying families with a child or adult affected by these conditions, as well as healthy families.

Kidney failure, weight loss, and gut health study
This study looks at how gut bacteria might affect weight loss in people with kidney failure who are on dialysis. It may help find new ways to prevent or treat weight loss in this condition.
BrusselsAges 18 years+ - NCT01137643Recruiting
Sharing blood and tissue samples for blood cancer research
This trial collects tissue, blood, and other body fluid samples from people with blood-related cancers. The goal is to help researchers study these diseases by building a source of samples for future testing.
Chapel Hill, North CarolinaAges 18–120 - NCT03268668Recruiting
Study brain clot makeup and blood markers after stroke
This study looks at the composition of a stroke blood clot and compares it with blood test results to understand treatment response, stroke cause, and prognosis. It may help doctors better predict outcomes and improve care after ischemic stroke.
BordeauxAges 18 years+ - NCT04804878Recruiting
Cancer care program for adults to help manage cancer
This study is a general cancer care program for adults (and in some cases people at risk for cancer). It aims to improve how cancer care is organized and delivered, and you may benefit from extra care support through the program.
Atlanta, GeorgiaAges 18 years+ - NCT03932786Recruiting
Study of health and wellbeing after retinoblastoma treatment
This study looks at long-term health outcomes—how patients are doing physically and in daily life—after treatment for retinoblastoma. It may help doctors understand what support or follow-up care could be most helpful after treatment.
Chicago, IllinoisAges Any age - NCT07131605Recruiting
How weight-loss surgery affects heart health and inflammation
This study looks at how weight-loss surgery affects heart health by checking markers of inflammation in the blood and how blood vessels work. It may help understand why surgery lowers heart risk for people with obesity.
Cotignola, RavennaAges 18 years+ - NCT07479134Recruiting
Producing stem cells for pancreatic cell research
This study collects skin or blood samples to create stem cells that can be turned into insulin-producing pancreatic cells. It may help people with diabetes and other beta cell disorders by providing cells for future research or treatments.
MilanAges 12–70 - NCT07517393Recruiting
Creating a Digital Lung Model Using AI and CT Scans
This study collects information from your chest CT scans and medical history to build an artificial intelligence model of how your lungs work. This 'digital twin' may help doctors better understand and predict lung health in the future.
Peschiera del Garda, VeronaAges 18 years+ - NCT05756985Recruiting
Providing fresh brain tissue to better understand glioblastoma
This study aims to improve understanding of glioblastoma (and gliosarcoma) by preserving live, usable brain-tissue samples during brain surgery. If you’re having repeat tumor surgery or your scans suggest these cancers, the study may ask to collect tissue for research.
Miami, FloridaAges 18 years+ - NCT00898313Recruiting
Study looks for cancer clues in people at high risk for lung cancer
This study enrolls adults who are being checked for possible lung cancer because of concerning symptoms or a high-risk situation. It aims to find molecular (cell/DNA-related) predictors that may help doctors better recognize lung cancer earlier.
Nashville, TennesseeAges 18 years+ - NCT05627713Recruiting
Studying monkeypox infection and vaccine in adults
This study looks at the medical and lab changes in people with suspected or likely monkeypox, and in adults who may be eligible for a monkeypox vaccine. Your participation helps researchers understand how infection and vaccination affect the body and how to improve care.

MRI Study to Understand Glioblastoma Biology Before Surgery
This study uses MRI scans to learn more about the biology of glioblastoma before and after surgery. It may help doctors understand how the tumor behaves and improve future treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT05540561Recruiting
Testing and monitoring for nitrous oxide use
This study looks at how nitrous oxide (also called laughing gas) is detected and how health effects may show up over time. It may help doctors better diagnose problems early and track changes after use.
BéthuneAges 14–65 - NCT05683873Recruiting
Study of heart stress after stroke using a blood marker
This study looks at how heart function changes soon after a new stroke, and whether a blood marker called GDF-15 can help explain or predict that change. It may help doctors better monitor heart stress after stroke and tailor care sooner.
DijonAges 18 years+ - NCT00899301Recruiting
Banking breast cancer and related tissue samples for future studies
This study collects and stores tissue and fluid samples from people with a breast lump or breast cancer so researchers can study cancer biology in the future. It may help future patients by allowing better lab tests and research on why breast cancer starts, grows, and comes back.

Common questions
- Are there clinical trials studying Biological collection?
- Yes. Clin2 currently lists 112 recruiting studies that include Biological collection, 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 Biological collection 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 Biological collection 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 Biological collection or a specific trial is right for you.
