Study of how immune cells respond in adults
This study looks at how your body’s immune system reacts in different tissues by collecting and storing samples for research. You might be able to join if you’re an adult and can consent, and if you don’t have certain bleeding risks that could make sample collection unsafe.
Bethesda, MarylandAges 18–120 - NCT06878482RecruitingPhase 4
Botulinum toxin injection for severe leg artery disease
This trial tests whether a single injection of botulinum toxin (a muscle-relaxing substance) into the leg can improve blood flow and help heal wounds in people with severe blocked leg arteries who cannot have standard procedures like angioplasty.
Yongin-si, Gyeonggi-doAges 20 years+ - NCT07362654Recruiting
Gluten challenge study in kids with celiac disease
This study looks at how the immune system of children with celiac disease responds to a small amount of gluten. It may help researchers understand the disease better and find new ways to monitor it.
MálagaAges 8–14 - NCT07194590RecruitingPhase 2
Equol and blood vessel health in women with kidney disease
This trial tests whether a supplement called equol, made from soy, can improve blood vessel function in postmenopausal women with moderate to advanced chronic kidney disease. Participants take equol or a placebo for several weeks to see if it helps their heart health.
Aurora, ColoradoAges 50 years+ - NCT07599176RecruitingPhase 1/Phase 2
Partial stem cell transplant for sickle cell disease from matched donors
This study tests a partial stem cell transplant from a matched donor to treat sickle cell disease. It may help reduce complications like strokes, organ damage, or pain crises.
Bethesda, MarylandAges 4–65 - NCT07381738RecruitingPhase 2
Cord blood transplant for Epstein-Barr virus diseases
This trial uses donated umbilical cord blood (a type of stem cell transplant) to treat people with serious illnesses caused by the Epstein-Barr virus. It's an option for those whose disease has not responded to other treatments.
Shanghai, Shanghai MunicipalityAges 14–80 - NCT07049588Recruiting
Finding early signs of Charcot-Marie-Tooth 1A
This trial looks for new markers of Charcot-Marie-Tooth 1A (CMT1A) early in the disease. Researchers hope to find signs that can help diagnose and track the disease better, which could lead to better treatments in the future.
MarseilleAges 10–30 - NCT06603363Recruiting
Statin effects on heart artery plaques seen on CT scans
This trial studies how short-term statin therapy changes plaque buildup in heart arteries. It uses CT scans to see if statins can make plaques more stable and reduce heart risks.
Budapest, BudapestAges 45–75 - NCT07312045Recruiting
Gum health and healing after non-surgical treatment
This study looks at how certain blood and saliva measurements relate to gum disease and healing after a deep cleaning. It may help find better ways to track gum health.
Merkez, ErzincanAges 18–65 - NCT06812767Enrolling by invitation
Chronic disease risks in working-age people
This study looks at risk factors for chronic diseases in healthy working-age adults. You may help researchers understand how to prevent conditions like heart disease or diabetes.
MoscowAges 18 years+ - NCT05632432Recruiting
Heart tissue grafts to help the heart after surgery
This trial tests whether transplanting tiny heart “micrografts” from the left heart chamber area can improve heart function after cardiac surgery. It is meant for people with weakened heart pumping and heart failure symptoms despite medicine.
Helsinki, UusimaaAges 18–75 - NCT07243964Recruiting
Predicting lung transplant outcomes with molecular analysis
This study uses advanced blood and tissue testing to predict how well a new lung will work after transplant. If you've had a lung transplant and are stable, you may help researchers improve care for future patients.
ShanghaiAges 18 years+ - NCT06411353Recruiting
Blood flow and sounds in new dialysis access
This study looks at blood flow and sounds in new arteriovenous fistulas (AVFs) during dialysis. If you need a new AVF in your forearm, this trial may help doctors understand how to make your fistula work better.
Bergamo, BergamoAges 18–90 - NCT06429332RecruitingPhase 4
Care bundle study for brain bleed on CT scan
This trial is testing a set of standard care steps (a 'care bundle') for people who have a sudden brain bleed (intracerebral hemorrhage) that shows up on a CT scan. It aims to see if this bundle improves recovery and outcomes.
Oklahoma City, OklahomaAges 18 years+ - NCT06397456Recruiting
Kidney education program for Black patients in the hospital
This study tests whether a special education and referral program helps Black patients with advanced kidney disease learn about their treatment options before they need dialysis or a transplant. If you join, you will get extra support while you're in the hospital.
Chicago, IllinoisAges 18–70 - NCT04216342RecruitingPhase 1
Testing a new breathing-drug ingredient in healthy adults
This early study (Phase 1) tests how safe and tolerable Fx-5A is, and how the body processes it, in healthy volunteers. It’s mainly looking to understand side effects and drug levels rather than treating a disease.
Bethesda, MarylandAges 18–99 - NCT01621594Recruiting
Testing new radiation methods for heart CT images
This trial studies newer ways to take heart and blood vessel CT scans while using radiation more carefully. It may help improve image quality for people needing coronary CT angiography.
Bethesda, MarylandAges 18–100 - NCT00001620Enrolling by invitation

Finding noninvasive markers of graft injury after heart transplant
This study looks for noninvasive markers (like blood or urine tests) that can show if a heart transplant is being injured. It aims to make monitoring safer and easier for children and adults with congenital heart disease who have had a transplant.

Common questions
- Are there clinical trials for blood disease?
- Yes. Clin2 currently lists 621 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.
