Prophylaxis in children

Joint Outcome StudyObjective

A multi-centre, open-label, two-arm, prospective, randomised clinical trial to compare full prophylaxis with an on-demand treatment regimen for joint haemorrhage 23

Study criteria

Sixty-five boys with haemophilia A aged between 6 and 30 months from 15 haemophilia centres were enrolled 23

The boys were randomised to receive a regimen of alternate day infusions of KOGENATE® Bayer at 25iu/kg to prevent haemorrhage or an on demand therapy regimen using ≥3 infusions totalling ≥80iu/kg KOGENATE® Bayer at the time of each joint haemorrhage 23

Outcomes
