Efanesoctocog alfa profylaxe u pacientů s hemofilií A se synoviální hypertrofií (SYNOVIIIUS)

6. listopadu 2026 aktualizováno: Sanofi

Prospektivní intervenční studium účinnosti profylaxe efanesoctocog alfa na synoviální hypertrofii u pacientů s hemofilií 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.
