E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the haemostatic effect of NNC-0156-0000-0009 during surgery procedures in patients with haemophilia B |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate the haemostatic effect of NNC-0156-0000-0009 during surgery and the postoperative period
• To evaluate the general safety, including immunogenicity of N9-GP, when used for prevention and treatment of bleeding during surgery and the post-operative period |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Patients with haemophilia B, aged 13-70 years and with a FIX activity of ≤2%.
• Male patients with moderately severe or severe congenital haemophilia B with a FIX activity ≤2% according to medical records
• History of at least 150 exposure days to other FIX products
• Scheduled major surgery |
|
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 (central laboratory)
• 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)
• ALT >3 times the upper limit of normal reference ranges at screening (central laboratory)
• Immune modulating or chemotherapeutic medication |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Haemostatic effect during surgery evaluated by the four-point response scale, assessed by the Investigator/Surgeon
− Four-point response scale: Excellent, good, moderate, poor |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
• Consumption of N9-GP (U/kg BW) during surgery and post-operative period
• Transfusion requirements (fulfilling transfusion criteria) during surgery and the post-operative
period
• Haemoglobin pre and post surgery start (0, 1h, 24 h and every 24 hours in the post-operative
period)
• AE and SAEs reported during the trial period until the last visit
• Incidence of inhibitors against FIX (≥0.6 BU) until the last visit |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
• During surgery is defined as the time from knife to skin until last stitch.
• The post-operative period is defined as the time from Day 1 to Day 13 (this period can be
extended with one additional week if judged be the Investigator). The patient can be discharged
earliest at the Day 3, and can have the EOT visit earliest at Day 6.
• The last visit is defined as the EOT visit if the patient continues in the extension trial and as the
follow-up visit if the patient does not continue in the extension trial. The EOT visit cannot be
performed sooner than Day 6 and latest Day 13 (this period can be extended with one additional
week if judged by the Investigator). The follow-up visit should take place 4 weeks ± 2 weeks
after the EOT visit. |
