  Purpose

This trial is conducted in Africa, Asia, Europe, Japan and North America. The aim of this trial is to evaluate the safety and efficacy, including pharmacokinetics (the rate at which the body eliminates the trial drug), of NNC-0156-0000-0009 when used for treatment and prophylaxis of bleeding episodes in patients with haemophilia B.

Primary Outcome Measures:
  • Incidence of inhibitory antibodies against factor IX defined as titre equal to or above 0.6 BU (Bethesda Units) [ Time Frame: 52 weeks after treatment start for patients on prophylaxis ] [ Designated as safety issue: No ]
  • Incidence of inhibitory antibodies against factor IX defined as titre equal to or above 0.6 BU (Bethesda Units) [ Time Frame: 28 weeks after treatment start on on-demand treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Haemostatic effect of NNC-0156-0000-0009 when used for prophylaxis of bleeding episodes, assessed as success/failure based on a four-point scale for haemostatic response [ Time Frame: 52 weeks after treatment start for patients on prophylaxis ] [ Designated as safety issue: No ]
  • Haemostatic effect of NNC-0156-0000-0009 when used for treatment of bleeding episodes, assessed as success/failure based on a four-point scale for haemostatic response [ Time Frame: 28 weeks after treatment start on on-demand treatment ] [ Designated as safety issue: No ]
  • Number of bleeding episodes per patient during routine prophylaxis [ Time Frame: 52 weeks after treatment start for patients on prophylaxis ] [ Designated as safety issue: No ]
  • Factor IX trough levels [ Time Frame: 52 weeks after treatment start for patients on prophylaxis ] [ Designated as safety issue: No ]
  • Factor IX trough levels [ Time Frame: 28 weeks after treatment start on on-demand treatment ] [ Designated as safety issue: No ]
  • Incidence of adverse events (AEs) [ Time Frame: at 56 weeks ±2 weeks for patients on prophylaxis ] [ Designated as safety issue: No ]
  • Incidence of adverse events (AEs) [ Time Frame: at 32 weeks ±2 weeks for patients on on-demand treatment ] [ Designated as safety issue: No ]
  • Incidence of serious adverse events (SAEs) [ Time Frame: at 56 weeks ±2 weeks for patients on prophylaxis ] [ Designated as safety issue: No ]
  • Incidence of serious adverse events (SAEs) [ Time Frame: at 32 weeks ±2 weeks for patients on on-demand treatment ] [ Designated as safety issue: No ]
  • Host Cell Proteins (HCP) antibodies [ Time Frame: 52 weeks after treatment start for patients on prophylaxis ] [ Designated as safety issue: No ]
  • Host Cell Proteins (HCP) antibodies [ Time Frame: 28 weeks after treatment start on on-demand treatment ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Prophylaxis, high dose (trial duration 52 weeks) Drug: NNC-0156-0000-0009
One single dose administered intravenously (into the vein) once weekly. Patients will receive instruction on how to treat any bleeding episode they may experience
Experimental: Prophylaxis, low dose (trial duration 52 weeks) Drug: NNC-0156-0000-0009
One single dose administered intravenously (into the vein) once weekly. Patients will receive instruction on how to treat any bleeding episode they may experience
Experimental: On-demand (trial duration 28 weeks) Drug: NNC-0156-0000-0009
Patients will treat themselves with either a low or a high dose dependent on the severity of the bleeding episode
