Run by Hospices Civils de Lyon · NCT07723560 · Data updated 2026-11-12
This observational study looks at how efanesoctocog alfa (Altuvoct) is used around surgery in people with hemophilia A to see if it helps control bleeding.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are people with hemophilia A who are undergoing surgery and are treated with Altuvoct.
✕Probably not a fit
Patients who are not receiving Altuvoct or who have inhibitors, severe liver or kidney disease, or other coagulation disorders may not experience the same benefits.

What this trial studies
This study observes the perioperative use of efanesoctocog alfa in hemophilia A patients undergoing surgery. It focuses on real-world administration and outcomes to understand how the ultra-long-acting FVIII product performs during surgical procedures. Data will come from clinical practice at a Lyon-area center and involve patients treated with Altuvoct. The aim is to identify practical dosing patterns and safety signals in the surgical setting. The study does not assign interventions but analyzes data from routine care.
Why it matters
Potential benefit: If successful, the findings could clarify how efanesoctocog alfa supports bleeding control during surgery and guide better perioperative management.
How similar studies have gone: Previous work in similar perioperative uses of extended-half-life FVIII suggests potential benefits, but this exact surgical context is relatively novel.
