Summary

This study gives people with moderate or severe hemophilia A who finished a previous trial continued access to the drug efanesoctocog alfa. The drug is a lab-made clotting factor that helps prevent bleeding episodes. Researchers will monitor safety and how well it controls bleeding until the drug becomes commercially available or until March 2027.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Efanesoctocog alfa (a lab-made clotting factor protein)

What this could lead to

If successful, this study will show that long-term use of efanesoctocog alfa is safe and effective at preventing bleeding episodes in people with hemophilia A.

What could go wrong

This is an open-label roll-over study, not a randomized trial, so results may be less definitive. Side effects or reduced effectiveness over time are possible, and the drug may not work for everyone.
