Testing a blood clotting medication to prevent bleeding in hemophilia A

This trial is testing SCT800, a man-made version of a protein your body needs to form blood clots. The study wants to see if this medication can safely help people with severe hemophilia A prevent bleeding episodes and control bleeds when they happen. This medication was already approved and available in China starting in 2021, and now researchers want to learn more about how well it works in patients who have never used this type of treatment before.

Severe hemophilia A means your body cannot make enough clotting factor on its own, so you bleed easily and can have serious, life-threatening bleeds. This medication offers a way to replace that missing clotting factor and prevent bleeding problems—but researchers need to study it carefully in people who are brand new to this type of treatment to make sure it's truly safe and effective.
