Rochester, MinnesotaAges 18–65 - NCT04077762Recruiting
Radial vs femoral access to reduce bleeding in heart procedures
This study compares two ways doctors can reach the heart during a catheter procedure: through the wrist (radial) or the groin (femoral). It aims to reduce bleeding and access-site complications, especially when patients may need a balloon/stent (PCI).
San Francisco, CaliforniaAges 18 years+ - NCT06998641Recruiting
Chitosan gauze for bleeding tears after childbirth
This trial tests whether a special gauze made with chitosan (a natural substance that helps blood clot) can stop bleeding from minor tears after childbirth without needing stitches. It may offer a simpler, gentler option for women with small tears.
IstanbulAges 18–48 - NCT07157423RecruitingPhase 4
A study of a medicine for heavy bleeding after childbirth in India
This study tests a medicine called eptacog alfa to see if it is safe for women in India who have severe bleeding after giving birth. It is for women who did not get better with standard treatments to help the uterus contract.
Belagavi, KarnatakaAges 18 years+ - NCT07575308RecruitingPhase 2
ALN-6400 for Heavy Bleeding in von Willebrand Disease
This trial tests a new medicine called ALN-6400 in teenage and adult women with von Willebrand disease (a blood clotting condition) who experience heavy menstrual bleeding. The goal is to see if this treatment can reduce bleeding and improve quality of life.
Los Angeles, CaliforniaAges 16–45 - NCT07639853Enrolling by invitation
Doctor feedback survey on Concerto Versa coils
This study gathers feedback from doctors who use Concerto Versa detachable coils (small metal devices that help treat brain aneurysms). The survey helps improve how these coils work and are used.
El Paso, TexasAges 22 years+ - NCT06511778RecruitingPhase 4
Bone wax to control bleeding during heart surgery
This trial tests a special bone wax to see if it helps control bleeding from the breastbone during heart surgery. It is for people having open-chest heart surgery with a heart-lung machine who also have certain bleeding risk factors.
Raleigh, North CarolinaAges 21 years+ - NCT04298723Recruiting
Left atrial appendage closure vs blood thinners after brain bleed
This trial compares a procedure that blocks a heart blood-choke point (the left atrial appendage) versus taking blood thinners by mouth. It is for people with atrial fibrillation who have had a brain bleed and may be safer avoiding long-term blood thinners.
Mannheim, Baden-WurttembergAges 18 years+ - NCT06820177RecruitingPhase 4
Tranexamic acid to reduce bleeding during abortion or miscarriage
This trial is testing if a medicine called tranexamic acid (TXA) can help reduce bleeding during a second-trimester abortion or miscarriage procedure. The goal is to make the procedure safer for patients.
San Diego, CaliforniaAges 18 years+ - NCT06725732RecruitingEarly Phase 1
Nebulized tranexamic acid for reducing bleeding during sinus surgery
This early-phase study tests if giving tranexamic acid (a medicine that helps blood clot) through a mist into the nose and sinuses during sinus surgery can reduce bleeding. It is designed for adults who are otherwise healthy and undergoing a common type of sinus surgery called functional endoscopic sinus surgery (FESS).
AsyutAges 18–65 - NCT06664775RecruitingPhase 3
Comparing two bleeding-control patches during open surgery
This study tests a special patch called TachoSil against a standard surgical pad (Surgicel) to see which works better for controlling minor oozing during open abdominal, chest, or pelvic surgeries. It may be an option if you are having certain types of surgery and have a small area of mild bleeding that needs help to stop.
Torrance, CaliforniaAges 1 month+ - NCT06429787Recruiting
Safety study of BALFAXAR vs. Kcentra for urgent blood thinner reversal
This study compares the safety of two medications, BALFAXAR and Kcentra, used to quickly reverse the effects of blood thinners (like warfarin) in people who need urgent surgery or a procedure. It helps doctors understand which option may be safer for patients in this situation.
Boston, MassachusettsAges 18 years+ - NCT06425614Recruiting
Blood Cell Recycling During Heart Surgery Trial
This trial tests whether giving back a patient's own platelets and red blood cells during heart surgery can reduce bleeding and the need for donor blood transfusions. It is for people having certain types of high-risk heart surgery with a heart-lung machine.
Bordeaux, FranceAges 18 years+ - NCT06026436Recruiting
Predicting clot and bleeding risk in kidney disease patients after a heart attack
This trial tests whether a blood test looking at platelets and tiny cell particles can help predict future blood clots or bleeding in people who have both chronic kidney disease and a recent heart attack. The goal is to improve treatment safety.
MarseilleAges 18–90 - NCT05774717RecruitingPhase 1
Tranexamic acid for bleeding after open nose surgery

- Yes. Clin2 currently lists 269 recruiting bleeding 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 bleeding 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 bleeding 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.
