1.Informed consent obtained before any trial-related activities (trial-related activities are any procedure that would not have been performed during normal management of the subject.)
2.Clinical diagnosis of congenital haemophilia A or B with a current positive inhibitor titre and a known peak inhibitor of >5 BU (present or in the past) to human FVIII or IX and known anti-human FVIII or IX anamnestic response
3.Male subject, 12 years of age or older. (=18 years old in Croatia, France and UK)
4.Minimum of 2 joint bleeds (in haemarthroses of ankles, knees, or elbows) requiring haemostatic drug treatment within the previous 6 months, or at least 4 joint bleeds (haemarthroses of ankles, knees, or elbows) requiring haemostatic drug treatment within the previous 12 months at trial entry.
5.Subject has adequate venous access at screening visit as judged by the Investigator
6.The subject or caregiver is capable of assessing the bleed
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes

Name Time Method Main Objective: To evaluate the safety of five escalating doses of NN1731 in haemophilia subjects with inhibitors being treated for acute joint bleeds.;Secondary Objective: •To evaluate the efficacy of NN1731 for treatment of acute joint bleeds in haemophilia subjects with inhibitors<br>•To evaluate the immunogenicity of NN1731 <br>•To evaluate the pharmacokinetics of NN1731<br>;Primary end point(s): •Adverse events <br>-Non-serious adverse events occurring from the first administration of trial product until 7 days after first trial product administration.<br>-Serious adverse events are collected from the first administration of trial product to the end of subjects’ participation in the trial.<br>Clinical symptoms associated with the joint bleeds are evaluated as efficacy parameters and should not be recorded as adverse events unless the subject or the Investigator believes it should be considered as an adverse event.<br>
