Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective is to evaluate the safety and efficacy of the treatment with BAY 81-8973 for prophylaxis and treatment of breakthrough bleeds in children with haemophilia A;Secondary Objective: The secondary objectives are - To assess the safety and efficacy of BAY 81-8973 during surgeries. - To assess incremental recovery of BAY 81-8973. - To assess pharmacokinetic parameters in a subset of children.;Primary end point(s): The primary variable is the annualized number of total bleeds (sum of spontaneous bleeds and traumatic bleeds) during prophylaxis that occur within 48 h of the last prophylaxis infusion. Both joint and non-joint bleeding will be assessed.;Timepoint(s) of evaluation of this end point: Continuous throughout duration of study

Secondary

MeasureTime frame
Secondary end point(s): •Subject/parents' assessment of the response of treatment of bleeding events which is assessed as excellent, good, moderately well or poorly. •Annualized number of total bleeds (sum of spontaneous and trauma bleeds) during prophylaxis treatment •Assessment of adequacy of haemostasis during surgical interventions •Number of infusions for the treatment of a bleed •Consumption of FVIII;Timepoint(s) of evaluation of this end point: Continuous throughout duration of study
