Investigating Safety and Pharmacokinetics of 2 Different Single Doses of NNC128-0000-2011 in Haemophilia A or B Patients

Study Overview
=================
Brief Summary
-----------------
This trial is conducted in Europe and Japan. The aim of this trial is to assess the safety and pharmacokinetics (the rate at which the body eliminates the trial drug) of single doses of NNC128-0000-2011, when administered i.v. (intravenously) to haemophilia patients.
