Efanesoctocog -Alfa -Prophylaxe bei Patienten mit Hämophilie A mit synovialer Hypertrophie (SYNOVIIIUS)
Prospektive interventionelle Untersuchung der Wirksamkeit der Efanesoctocog -Alfa -Prophylaxe zur Synovialhypertrophie bei Patienten mit Hämophilie A.
The objective of the study is to assess the improvement of synovial hypertrophy during the 12 months of efanesoctocog alfa prophylaxis once per week (QW) in joints with existing evidence of synovial hypertrophy in participants with hemophilia A.
The study duration for each participant is approximately 12 months.

Inclusion Criteria:
-
Participant is diagnosed with moderate to severe hemophilia A (defined as less than or equal to (≤)5 percent (%) of endogenous FVIII clotting activity) at the time of consent/assent.
-
Participant is more than or equal to (≥)12 years old at the time of consent/assent.
