Study gut microbiome in older adults with well-controlled HIV
This trial studies how the bacteria in your gut (“microbiome”) relate to frailty (weakness/low physical resilience) in people with HIV who are stably doing well on treatment. It may help researchers understand why some people become frail and how the gut may play a role.

Genome study across diverse populations with IBD
This study looks at the genes of people with inflammatory bowel disease (IBD) and healthy volunteers to understand why IBD affects different populations. You may join if you have Crohn's disease, ulcerative colitis, or undetermined IBD, or if you are a healthy person without any IBD history.
Toronto, OntarioAges Any age - NCT03287193Recruiting
Study genes behind rare, genetic-looking illnesses
This study is trying to find the gene or body-process cause of rare diseases (or rare forms of common diseases) when the reason is not yet understood. If you qualify, you may be asked to give genetic and health information that could help doctors diagnose and understand the condition better.

Nanoparticles to help guide prostate cancer surgery
This Phase 1 study tests nanoparticles (tiny particles) that are meant to help surgeons better find and remove prostate cancer tissue during surgery. You may be offered standard prostate surgery plus imaging with a study tracer to guide the operation.
New York, New YorkAges 18 years+ - NCT04099290Recruiting
Blood DNA test in newly diagnosed head and neck cancer
This study looks at “circulating tumor DNA” (tumor DNA found in blood) in people with newly diagnosed, locally advanced head and neck squamous cell cancer. Researchers want to see how the blood DNA levels relate to the cancer and how it may guide treatment after surgery.
Chapel Hill, North CarolinaAges 18 years+ - NCT03997253Recruiting
Improving long-term survival after organ transplant
This study follows kidney, liver, or heart transplant recipients to better understand how to improve their long-term health and survival. Researchers at several hospitals in France will collect information from participants to learn what helps people stay healthy after a transplant.
LimogesAges 18 years+ - NCT03626233Recruiting
Study blood vessel changes in preeclampsia and growth restriction
This study looks at how the placenta and blood vessels work in pregnancy, especially in preeclampsia and babies with growth restriction (IUGR). It may help researchers build a blood sample collection and learn what could predict or explain these complications.
CréteilAges 18 years+ - NCT02688517Recruiting
Tests tumor genomics using blood and stored tissue
This study looks at the genetic information (DNA) from your blood and from saved tumor tissue to better understand certain cancers, especially rare cancers with a poor outlook. It may help researchers learn why these cancers behave the way they do and guide future treatments.
Brick, New JerseyAges 1 year+ - NCT01852448Recruiting
Study genes affecting insulin in people with cystic fibrosis
This study looks at how genes may affect insulin and “incretin” hormones in people with cystic fibrosis. It may help researchers understand why some people develop blood-sugar problems and how to predict or prevent them.
Philadelphia, PennsylvaniaAges 2 years+ - NCT01050504Recruiting
Donate blood and tissue to study recurrent or metastatic cancers
This study collects and studies blood and, when possible, small tissue samples from people with prostate or bladder/urothelial cancer that has come back or spread. The goal is to better understand these cancers and support future research that may lead to better care.
Seattle, WashingtonAges 18 years+ - NCT00083512Recruiting

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.
