Recruiting studies
- NCT05292001RecruitingPhase 4
Single IV iron dose for anemia after leg or pelvic fractures
This trial tests whether giving a one-time IV iron treatment can improve anemia (low blood count) after surgery for a leg or pelvic fracture. It may help your body make red blood cells faster after blood loss from the injury and operation.
Portland, OregonAges 18–89 - NCT06606119Recruiting
Brain, bone marrow, and gut study after major injury
This study is looking at how the brain, bone marrow, and gut interact after a severe injury. It may help doctors understand how to better treat trauma patients.
Gainesville, FloridaAges 18–100 - NCT06235749Recruiting
Calcium gluconate to reduce bleeding during planned C-section
This study tests whether giving calcium gluconate during a planned cesarean can reduce blood loss. It may be an option for women who are at least 35 weeks pregnant and have no conditions that affect calcium or heart rhythm.
BeershebaAges 18 years+ - NCT04811313Recruiting
Tranexamic acid for children having hip bone surgery
This study tests whether tranexamic acid (a medicine that helps reduce bleeding) can safely help children during certain hip bone operations. It may help lower blood loss around the surgery.
AsyutAges 1–18 - NCT05774717RecruitingPhase 1
Tranexamic acid for bleeding after open nose surgery
This Phase 1 study tests whether tranexamic acid (a medicine that helps reduce bleeding) can lessen bleeding, swelling, and bruising after open rhinoplasty. You may be asked to take it around the time of surgery if you meet safety and lab criteria.
Nashville, TennesseeAges 18 years+ - NCT05488457RecruitingPhase 2
Oxytocin timing and effects during planned C-section
This study looks at how oxytocin (a medicine often used to help with labor and uterine contractions) moves through the body and what it does during a non-emergency C-section. It may help improve how oxytocin is used in the future for safer, more predictable delivery care.
Stanford, CaliforniaAges 18–50 - NCT05312658Enrolling by invitation
Aortic compression during C-section to reduce blood loss
This trial studies whether gently compressing the major blood vessel in the abdomen during a C-section can reduce blood loss. It may help you stay safer during surgery, especially by lowering the chance of heavy bleeding.
StockholmAges 18 years+ - NCT04906863Recruiting
Genetic study for early dementia in adults and families
This trial studies genes to better understand why some people develop dementia and memory problems earlier in life. It may help researchers find clearer causes and improve future testing and treatments for families affected by dementia.
New York, New YorkAges 35 years+ - NCT03553186RecruitingPhase 3
Tranexamic acid to reduce bleeding in spine surgery
This Phase 3 trial tests whether tranexamic acid can reduce bleeding during major spine fusion surgery for adults with scoliosis or spine degeneration. It may help lessen blood loss and the need for transfusions, while monitoring safety.
New York, New YorkAges 18–80 - NCT02314988RecruitingPhase 2/Phase 3
Tranexamic acid to reduce bleeding in spine surgery
This trial tests whether tranexamic acid (a medicine that helps blood clot) can reduce blood loss during long spine surgery after an injury. It may help lower the chance of needing transfusions and manage surgical bleeding.
San Francisco, CaliforniaAges 18–80 - NCT01731444RecruitingPhase 1
Phenylephrine gel to reduce bleeding in burn skin surgery
This early-stage study tests a medication (phenylephrine) used during burn wound surgery to help control bleeding. If it works, it may make skin grafting safer and reduce how much bleeding surgeons see.
Winnipeg, ManitobaAges 18–75 - NCT02604563Recruiting
Aging, blood changes, and health in older adults
This study examines why some older adults develop changes in their blood cells that may affect their health. Researchers will look for links between these blood changes, aging, and common health problems in older people.
St Louis, MissouriAges 50 years+ - NCT05312983Recruiting
Testing new hearing tests to better diagnose age-related hearing loss
This study is developing a set of hearing tests to more precisely identify age-related hearing loss. It may help you (or the study team) better understand what type of hearing problem you have and how to guide next steps.
ParisAges 18 years+ - NCT06492109Recruiting
Blood study on sleep loss
This study looks at blood samples to understand how sleep loss affects the body. It may help find new ways to diagnose or treat sleep problems.
Hangzhou, ZhejiangAges 18–80 - NCT06717334Recruiting
Lung cancer screening for people with unexplained weight loss
This study looks at using low-dose CT scans to check for lung cancer in people who have lost some weight without a clear reason. The goal is to see if screening can find lung cancer early in this group.
Basking Ridge, New JerseyAges 50–80 - NCT06147843Recruiting
Study on weight loss in ALS patients from France and Germany
This study looks at why some people with ALS lose weight and what factors are involved. It follows patients in France and Germany to better understand weight changes and help improve care.
LilleAges 18 years+ - NCT07294131RecruitingPhase 2
Preventing muscle loss in hospitalized older adults
This trial tests a special exercise approach using blood-flow restriction and a video game to help older adults in the hospital keep their muscle strength. The goal is to find a safe way for bedridden patients to exercise and recover better.
AntwerpAges 65 years+ - NCT06565104Recruiting
Sleep study for people with high blood pressure
This study tests whether improving sleep can lower blood pressure. It is for people with elevated blood pressure or hypertension who speak English or Spanish.
New York, New YorkAges 20 years+ - NCT01927783Recruiting
Community weight loss program for people in Washington area
This study tests a community-based behavioral weight loss program. It may help participants learn practical habits for healthier weight by working with people in local faith communities.
Bethesda, MarylandAges 19–85 - NCT06046651Recruiting
Blood sample collection for lab research
This study collects blood samples from healthy adults to help researchers learn more about how to run lab tests. It involves one visit or at-home collection and might help future medical research.
San Francisco, CaliforniaAges 18 years+ - NCT05449119Recruiting
Study links gut health, diet, and thinking and movement in seniors
This study looks at how differences in gut bacteria and nutrition may relate to changes in thinking and movement in people over 75 who have a reduced appetite (“small eaters”). It may help doctors better understand what could be contributing to these problems and how nutrition might play a role.
DijonAges 75 years+ - NCT06584357Recruiting
Digital and blood markers linked to brain scans in older adults
This study is looking for older adults (60–90) who are either cognitively normal, have mild cognitive impairment (MCI), or have mild-to-moderate Alzheimer's dementia. It aims to see how digital tests and blood-based markers relate to brain scans (amyloid and tau PET). You will need a study partner, undergo MRI and PET scans, and give blood samples.
Atlantis, FloridaAges 60–90

Common questions
- Are there clinical trials for blood loss?
- Yes. Clin2 currently lists 70 recruiting blood loss 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 loss 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 loss 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.
