Recruiting studies
- NCT07285460RecruitingPhase 3
Fitusiran for young boys with hemophilia A or B
This trial tests if fitusiran, given as a shot, can help prevent bleeding in boys ages 1 to 12 with severe hemophilia (factor VIII under 1% or factor IX at 2% or lower). It includes boys with or without inhibitors and aims to understand safety and how well it works.
Los Angeles, CaliforniaAges 1–11 - NCT07545395RecruitingPhase 3
Safety study of KN057 blood clot prevention in hemophilia
This study tests whether KN057, a new preventive medicine, is safe for males with hemophilia A or B. It aims to help prevent bleeding episodes without causing unwanted blood clots.
Tianjin, Tianjin MunicipalityAges 12–65 - NCT04647227RecruitingPhase 4
SEVENFACT® to reduce bleeding in hemophilia with inhibitors
This trial studies whether SEVENFACT® can reduce bleeding episodes in people with hemophilia A or B who have inhibitors (proteins that make standard treatments less effective). It also tests how well people can track bleeding and medicine use during the study.
Phoenix, ArizonaAges 12–100 - NCT03961243RecruitingPhase 1
Gene therapy for hemophilia B using a FIX gene treatment
This trial tests a one-time (or limited) gene therapy meant to help the body make more factor IX (FIX), which can reduce bleeding in people with hemophilia B. You may be able to qualify if you have significant bleeding history, no factor IX “blockers” (inhibitors), and can follow strict safety and pregnancy-prevention rules.

Common questions
- Are there clinical trials for hemophilia b?
- Yes. Clin2 currently lists 28 recruiting hemophilia b 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 hemophilia b 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 hemophilia b 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.
