rFVIIa Prophylaxis in Children With Hemophilia A and Inhibitors (ENJOIH)

April 5, 2013 updated by: Elena Santagostino, Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico

An Investigator-initiated Study on rFVIIa Prophylaxis in Children With Hemophilia A and Inhibitors - European Initiative to Prevent Joint Damage in Hemophilia A Children With Inhibitors

The study evaluates the efficacy and safety of a prophylactic treatment with recombinant activated FVII in reducing the frequency of joint bleeds and the development of joint damage in children with hemophilia A who develop high-titer inhibitors.

Study Overview

Detailed Description

This is a multicentre, randomised, controlled study designed to gain evidence of the advantage of the prophylactic, daily treatment with recombinant activated FVII as compared to the conventional on demand therapy in reducing the bleeding frequency and preserving the orthopaedic status in hemophilic children with inhibitors.
