Profilassi di efanesoctocog alfa in pazienti con emofilia A con ipertrofia sinoviale (SYNOVIIIUS)

6 novembre 2026 aggiornato da: Sanofi

Studio interventistico prospettico sull'efficacia dell'efanesoctocog alfa profilassi sull'ipertrofia sinoviale nei pazienti con emofilia 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.
