First seen Jan 21, 2026 · Last updated May 08, 2026 · Updated 15 times

Summary

This study looks at whether a newer medication called Emicizumab works better than the standard Factor VIII treatment to prevent bleeding in children and teens with hemophilia A who play sports. Participants must be between 6 and 19 years old, have moderate or severe hemophilia A, and already be taking one of these treatments. The study will track how many bleeds happen during sports and measure joint health and bone density over time.
