Recruiting studies
- NCT06857604Recruiting
Immune defects behind common blood diseases in young people
This study looks at how problems with the immune system might be linked to certain blood disorders in people under 25. The goal is to better understand what causes these conditions and find better ways to treat them.
Montreal, CanadaAges Up to 25 years - 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.
DijonAges Any age - NCT05370079Recruiting
Control group for people with specific serious illnesses
This trial includes a “control” group of people with certain diseases to compare outcomes against another group. If you qualify, you may receive the standard approach used in usual care rather than the experimental treatment.
BronAges 18 years+ - NCT06252493Recruiting
PET/MR scan for Crohn's disease scar tissue
This study is testing a new imaging method that uses a special PET/MR scan to see how active Crohn's disease is in your bowel. The scan uses a harmless radioactive tracer that attaches to scar tissue, which may help doctors better understand the disease and guide treatment.
Charlestown, MassachusettsAges 18–99 - NCT06434207Recruiting
Heart defect study in newborns to understand blood clots
This study looks at tiny particles from cells in newborns with heart defects to understand blood clot risks. It aims to find ways to prevent clots after heart surgery.
Boston, MassachusettsAges 1 day–1 week - NCT05181826Recruiting
Blood collection study for cancer and benign diseases
This study collects blood samples from people with different health conditions (cancer, diabetes, liver disease, etc.) and from healthy volunteers. The goal is to find markers in the blood that could help detect or monitor diseases.
Redondo Beach, CaliforniaAges 18 years+ - NCT05904301Recruiting
Registry for autoimmune and autoinflammatory disease patients
This study builds a nationwide list (registry) of people with certain autoimmune or inflammation-related illnesses. It helps researchers understand these diseases better over time, which can guide future care.
YerevanAges Any age - NCT06414031RecruitingPhase 3
Transfusion reduction in abdominal surgery with tranexamic acid
This trial tests whether a medicine called tranexamic acid can help reduce the need for blood transfusions during major abdominal surgeries. It's for people having surgery to remove part of the esophagus, stomach, colon, rectum, pancreas, or liver.
Dresden, SaxonyAges 18 years+ - NCT03779854RecruitingPhase 2
Preventing graft-versus-host disease in kids after stem cell transplant
This trial tests whether removing certain immune cells (T cells) from the donor transplant can lower the risk of chronic graft-versus-host disease (long-term immune attack after transplant) in children and young adults with blood cancers. If you qualify, it may help improve transplant outcomes while tracking safety and side effects.
Los Angeles, CaliforniaAges 6 months–26 years - NCT05403151Recruiting
Healthy blood vessel and control study
This study looks at healthy adults and how their blood vessels work. It may help researchers understand normal circulation so they can better compare changes in future conditions.
Bethesda, MarylandAges 18–90 - NCT06396871Recruiting
Blood cell study in metabolic diseases
This study looks at blood cells and factors in people with metabolic diseases like fatty liver, prediabetes, or type 2 diabetes. It aims to better understand these conditions by comparing them with healthy volunteers.
Dresden, SaxonyAges 18 years+ - NCT07249346RecruitingPhase 2
Preventing GVHD after stem cell transplant with three drugs
This trial tests a three-drug combination (cyclophosphamide, tacrolimus, and ruxolitinib) to prevent graft-versus-host disease (GVHD) after a stem cell transplant. It is for people with certain blood cancers who have a matched donor and can tolerate high-dose chemotherapy.
Columbus, OhioAges 18 years+ - NCT07304947Recruiting
Guiding blood flow during Moyamoya surgery in children
This study tests if careful monitoring and management of blood flow during surgery can help children with Moyamoya disease recover better after EDAS. It aims to improve safety and outcomes by adjusting treatment based on real-time heart function.
SeoulAges 1 month–18 years - NCT07353502Recruiting
Early Alzheimer's brain connection study
This study looks at a specific brain pathway that may be linked to early memory loss in Alzheimer's disease. It compares people with early Alzheimer's to healthy older adults to understand how connections between brain cells start to break down.
Yiwu, ZhejiangAges 50 years+ - NCT00106925Recruiting
Long-term follow-up for people after stem cell transplant
This study follows people who are at least 3 years out from their first stem cell transplant to learn how they are doing long term. It may help improve future transplant care by tracking outcomes over time.
Bethesda, MarylandAges 7–80 - NCT00081523Recruiting
Understanding How Sickle Cell Disease Develops Over Time
This research study follows people with sickle cell disease to learn how the condition affects their health over many years. By studying patients regularly, researchers hope to better understand the disease and improve care.
Washington D.C., District of ColumbiaAges 2–90 - NCT00704626Enrolling by invitation
Blood antibody tests in autoimmune brain and nerve diseases
This study looks at blood “auto-antibodies,” which are immune proteins that may attack the body, in people with certain brain and nerve conditions. It may help researchers better understand these diseases and how the immune system is involved.
Sacramento, CaliforniaAges 18 years+ - NCT07118137Recruiting
Memory loss in Alzheimer's disease study
This study looks at how memory changes over time in people with Alzheimer's or mild memory problems. It uses advanced brain scans to understand the disease better.
Trondheim, TrønderlagAges 55 years+ - NCT05436418RecruitingPhase 1/Phase 2
Lower-dose transplant medicines to prevent graft-versus-host disease
This early-phase study tests a lower dose of cyclophosphamide given after a stem cell transplant to prevent graft-versus-host disease (GVHD). It also uses sirolimus and mycophenolate to improve how well the donor immune system accepts the transplant, aiming to reduce side effects while keeping protection against GVHD.
Duarte, CaliforniaAges 12–120 - NCT00542230Recruiting
Blood sample study for sickle cell trait and controls
This study collects blood samples to learn more about sickle cell-related genetics and biology. You might benefit indirectly by helping researchers understand the condition, even though this is laboratory research rather than a medication trial.
Bethesda, MarylandAges 18–100 - NCT00902447Recruiting
Blood and tissue collection for future research studies
This trial is a tissue and blood bank that collects samples for future research. You may be asked to give blood and/or tissue again later, but it is meant to be done without interfering with your care.
Manhasset, New YorkAges 18–100 - NCT04752293Recruiting
Study of a kidney blood-pressure system in kids
This study looks at how a kidney-related blood-pressure system works in children and teenagers, comparing those with newly diagnosed primary (no known cause) high blood pressure to those with normal blood pressure. It may help doctors better understand childhood blood-pressure changes and guide future care.
Winston-Salem, North CarolinaAges 7–18 - NCT07743021Recruiting

Common questions
- Are there clinical trials for blood disease?
- Yes. Clin2 currently lists 636 recruiting blood disease studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a blood disease trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a blood disease trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
