This study is testing a drug called Nuwiq, a lab-made clotting factor, to prevent excessive bleeding during major surgery in women and girls with hemophilia A. About 28 participants will receive Nuwiq around the time of their surgery. Researchers will check if the drug successful…

This study tests a new medicine called marstacimab in children aged 1 to 17 with severe hemophilia A or B. The medicine is given as a weekly shot under the skin to prevent bleeding episodes. Researchers will compare how well it works to the children's own past year of standard tr…

This phase 3 study is testing whether a low, personalized dose of FEIBA (aPCC) can safely control bleeding in children and adults with hemophilia A who have inhibitors and are already taking emicizumab. The study will measure how well the blood clots after FEIBA is given and trac…

This trial tests a one-time gene therapy called BBM-H803 for adults with severe hemophilia A. The treatment uses a harmless virus to deliver a working gene to the liver, so the body can produce its own clotting factor VIII. The study involves 55 participants and will check safety…

This early-stage study tests a new drug called SR604 in healthy people and those with hemophilia A, B, or factor VII deficiency. The main goal is to check safety and how the drug moves through the body. About 31 participants will receive single or multiple doses to find the right…

This study looks at whether Emicizumab, a newer drug, prevents bleeding during sports better than standard Factor VIII in children with moderate to severe hemophilia A. About 72 kids aged 6 to 19 who already play sports and take one of these drugs will be followed. The goal is to…

This study tests a single-dose gene therapy called GS1191-0445 in 50 Chinese men with hemophilia A. The treatment uses a harmless virus to deliver a working gene to the liver, helping the body produce its own clotting factor. The goal is to reduce bleeding episodes and the need f…

This study in Taiwan will follow about 100 people with moderate to severe hemophilia A who are already taking efanesoctocog alfa (a clotting factor) as part of their routine care. Researchers will track joint health, bleeding rates, and safety over up to 5 years using medical rec…

This study is testing a new blood test that can diagnose single-gene disorders in unborn babies using a sample from the mother. The test looks at fetal DNA found in the mother's blood, which is safer than traditional invasive methods that carry a small risk of miscarriage. Resear…

This study monitors the safety of Jivi (damoctocog alfa pegol) in 20 Korean patients with hemophilia A who have used other treatments before. Researchers will collect data from routine clinic visits over about 8 months per participant, looking for any medical problems. No extra t…

This study follows 173 people with hemophilia A or B who previously received a single-dose gene therapy in a Pfizer trial. Researchers will track bleeding episodes, clotting factor levels, and any long-term side effects like blood clots or liver issues. The goal is to understand …

This study is testing a new, non-invasive method to predict bleeding risk in people with von Willebrand disease and other inherited bleeding disorders. Researchers will use a special microscope to look at tiny blood vessels under the tongue. The goal is to see if the density of t…

This study looks at whether ultrasound and other imaging can find hidden joint changes in people with hemophilia who have no obvious symptoms. Researchers will follow 46 patients for up to 12 weeks, using scans and physical exams to see if these hidden changes are active or inact…
