|
| E.2.2 | Secondary objectives of the trial |
• To evaluate clinical efficacy of haemostasis (treatment of bleeding episodes) of
NNC-0156-0000-0009
• To evaluate clinical efficacy of NNC-0156-0000-0009 in long term bleeding prophylaxis (number of bleeding episodes during prophylaxis)
• To evaluate efficacy of NNC-0156-0000-0009 by the surrogate marker for efficacy, FIX activity
• To evaluate general safety of NNC-0156-0000-0009 |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
| Previous participation in NN7999-3747, NN7999-3773 |
|
| E.4 | Principal exclusion criteria |
• Known history of FIX inhibitors based on existing medical records, laboratory report reviews
and patient and LAR interviews
• Current FIX inhibitors ≥0.6 BU
• Congenital or acquired coagulation disorders other than haemophilia B
• Previous arterial thrombotic events (e.g. myocardial infarction and intracranial thrombosis) or previous deep venous thrombosis or pulmonary embolism (as defined by available medical records)
• Any disease (liver, kidney, inflammatory and mental disorders included) or condition which, according to the Investigator’s judgement, could imply a potential hazard to the patient, interfere with trial participation, or interfere with trial outcome |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
| Incidence of inhibitory antibodies against FIX defined as titre ≥0.6 BU |
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
| The efficacy endpoints will be evaluated based on all available information until the EOT visit. The safety endpoints will be evaluated based on all available information until the last visit. |
|
| E.5.2 | Secondary end point(s) |
• Haemostatic effect of NNC-0156-0000-0009 when used for treatment of bleeding episodes, assessed on a four-point scale for haemostatic response (excellent, good, moderate and poor) by counting excellent and good as success and moderate and poor as failure
• Number of bleeding episodes during routine prophylaxis
• FIX trough levels
• Adverse Events (AEs) and Serious Adverse Events (SAEs)
• General safety endpoints including laboratory parameters, physical examination and vital signs |
|
| E.5.2.1 | Timepoint(s) of evaluation of this end point |
| The efficacy endpoints will be evaluated based on all available information until the EOT visit. The safety endpoints will be evaluated based on all available information until the last visit. |
