E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To evaluate the immunogenicity of NNC 0129-0000-1003 (hereafter referred to as N8-GP) in previously treated patients with Haemophilia A
- To evaluate the clinical efficacy of N8-GP in bleeding prophylaxis (number of bleeds during prophylaxis) |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate the clinical efficacy of N8-GP when treating bleeds in patients with haemophilia A
- To evaluate the safety of N8-GP when used for prevention of bleeds and treatment of bleeds in patients with haemophilia A
- To evaluate PK properties of N8-GP
- To evaluate Patient Reported Outcomes
- To evaluate the health economic impact of N8-GP treatment
- Generation of a population based PK-model for N8-GP |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Male patients with severe congenital haemophilia A (FVIII activity <1%, according to medical records)
- Documented history of at least 150 EDs to other FVIII products
- Age ≥12 years and body weight ≥ 35 kg (except for Croatia, The Netherlands, France, Russia and Israel where the lower age limit will be 18 years) |
|
E.4 | Principal exclusion criteria |
- Previous participation in this trial defined as withdrawal after administration N8-GP
- Any history of FVIII inhibitors
- FVIII inhibitors ≥ 0.6 BU/mL at screening
- HIV positive, defined by medical records with CD4+ count ≤200/µL or a viral load of >400000 copies/mL If the data is not available in medical records within last 6 months, CD4+ will be measured at the screening visit
- Congenital or acquired coagulation disorders other than haemophilia A
- Previous significant thromboembolic events (e.g. myocardial infarction, cerebrovascular disease or deep venous thrombosis) as defined by available medical records
- Platelet count < 50,000 platelets/µL (laboratory value at the screening visit)
- ALAT > 3 times the upper limit of normal reference ranges at central laboratory
- Creatinine level ≥ 1.5 times above upper normal limit (according to central laboratory reference ranges)
- Ongoing immune modulating or chemotherapeutic medication |
|
E.5 End points |
E.5.1 | Primary end point(s) |
- The Incidence rate of FVIII-inhibitors ≥0.6 BU
- Annualised bleeding rate in the prophylaxis arm |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The endpoints will be analysed based on all available information after approximately 24 months and 36 months until the end of trial (EOT) visit. |
|
E.5.2 | Secondary end point(s) |
- Haemostatic effect of N8-GP when used for treatment of bleeds, assessed on a four-point scale for haemostatic response (excellent, good, moderate and none) by counting excellent and good as success and moderate and none as failure. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The endpoints will be analysed based on all available information until the end of trial (EOT) visit and up to approximately 24 months and 36 months. |
