Primary Outcome Measures

Name	Time	Method
Main Objective: To assess the efficacy of concizumab administered s.c. once daily in preventing bleeding episodes in haemophilia A and B patients with inhibitors;Secondary Objective: 1. To assess the longer-term efficacy of concizumab in haemophilia patients with inhibitors<br>2. To assess the safety of concizumab in haemophilia patients with inhibitors<br>3. To assess the safety of administering recombinant factor VIIa (rFVIIa) to haemophilia patients with inhibitors that are exposed to concizumab<br>4. To assess the immunogenicity of concizumab in haemophilia patients with inhibitors;Primary end point(s): The number of bleeding episodes during at least 24 weeks from treatment onset.;Timepoint(s) of evaluation of this end point: During at least 24 weeks from treatment onset

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): - The number of spontaneous bleeding episodes during at least 24 weeks from treatment onset <br><br>- Number of treatment emergent adverse events (TEAEs) during at least 24 weeks from treatment onset;Timepoint(s) of evaluation of this end point: During at least 24 weeks from treatment onset<br><br>All endpoints referring to the time frame of at least 24 weeks will be<br>evaluated in the main part of the trial, defined to end when the last patient has completed a minimum of 24 weeks of dosing treatment with trial product (or has withdrawn). In addition, number of bleeding episodes during 76 weeks of treatment with prophylactic concizumab will be analysed.<br>
