San Diego, CaliforniaAges 18–110 - NCT07143019Recruiting
A new device for treating wide-necked brain aneurysms
This trial tests a special device (p48/64 MW HPC) to treat certain brain aneurysms that are wide-necked or have a shape that makes them hard to treat. It might help people with aneurysms that haven't ruptured or that have been treated before and are now coming back.
San Francisco, CaliforniaAges 18 years+ - NCT05958342RecruitingPhase 2
Calcium and vasopressin for bleeding shock after major injury
This trial tests whether giving calcium and vasopressin early can improve outcomes in people with major injury who are at risk for life-threatening bleeding shock. It mainly includes patients who need rapid blood transfusion and likely major surgery to stop bleeding.
San Francisco, CaliforniaAges 18–90 - 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+ - 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+ - NCT07565753RecruitingEarly Phase 1
Testing a medication to stop bleeding after tonsil removal
This study tests a medicine called tranexamic acid to help stop bleeding in children who had their tonsils removed and are now bleeding more than a day after surgery. Researchers want to see if this medicine can reduce the amount of bleeding and help children recover faster.
Davis, CaliforniaAges 2–17 - NCT03907046RecruitingPhase 3
Blood thinner study to prevent stroke after brain bleed
This Phase 3 study tests whether a blood thinner (apixaban) can help prevent another stroke and support recovery after you’ve had a brain bleed. You would be assigned to a treatment group, and the study checks safety and whether strokes can be reduced without causing dangerous bleeding.
Castro Valley, CaliforniaAges 18 years+ - NCT04098445Recruiting
Study of lung injury in children after stem cell transplant
This study follows children and teens who get a stem cell transplant to learn how lung problems develop over time. Your participation could help doctors better predict, prevent, and manage lung injury after transplant.

What taking part in a hemorrhage study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
