Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Inhibitory Antibodies Against Coagulation Factor VIII (FVIII) =0.6 Bethesda Units	The number of participants with inhibitory antibodies against coagulation factor VIII (FVIII) =0.6 Bethesda units was presented.	During the main phase of the trial (from 0-26 weeks of treatment)
Secondary	Frequency of Adverse Events Including Serious Adverse Events Reported During the Trial Period	The frequency of adverse events including serious adverse events reported during the main and extension phase of the trial. The data presented is the rate of AE i.e. number of AEs per patient years of exposue.	Main phase: (from 0-26 weeks of treatment) and full trial: (0 weeks to last patient's completion of the trial, an average of 4.5 years)
Secondary	Haemostatic Effect of N8-GP When Used for Treatment of Bleeding Episodes and Assessed as: Excellent, Good, Moderate, or None	Haemostatic effect of N8-GP for treatment of bleeding episodes was assessed by 4-point response scale: none, moderate, good or excellent. Evaluation during trial was done by patient and/or parent(s)/caregiver 8 hours after first injection as follows: Excellent: Abrupt pain relief and/or clear improvement in objective signs of bleeding within approximately 8 hours after a single injection; Good: Definite pain relief and/or improvement in signs of bleeding within approximately 8 hours after a single injection, but possibly requiring more than one injection for complete resolution; Moderate: Probable or slight beneficial effect within approximately 8 hours after the first injection, but usually requiring more than one injection; None: No improvement, or worsening of symptoms.	Main phase: (from 0-26 weeks of treatment) and full trial: (0 weeks to last patient's completion of the trial, an average of 4.5 years)
Secondary	Number of Bleeding Episodes During Prophylactic Treatment With N8-GP (Annualised Bleeding Rate)	The number of bleeding episodes per year reported during the prophylactic treatment with N8-GP.	Main phase: (from 0-26 weeks of treatment) and full trial: (0 weeks to last patient's completion of the trial, an average of 4.5 years)
Secondary	Consumption of N8-GP Per Bleeding Episode (Number of Injections)	The mean number of injections of N8-GP used for treatment of a bleed from start to stop of a bleed.	Main phase: (from 0-26 weeks of treatment) and full trial: (0 weeks to last patient's completion of the trial, an average of 4.5 years)
Secondary	Consumption of N8-GP Per Bleeding Episode (U/kg)	The mean consumption of N8-GP used for treatment of a bleed from start to stop of a bleed.	Main phase: (from 0-26 weeks of treatment) and full trial: (0 weeks to last patient's completion of the trial, an average of 4.5 years)
Secondary	Consumption of N8-GP During Prophylaxis (Number of Injections)	The mean number of injections of N8-GP used for treatment of a bleed from start to stop of a bleed during prophylaxis.	Main phase: (from 0-26 weeks of treatment) and full trial: (0 weeks to last patient's completion of the trial, an average of 4.5 years)
Secondary	Consumption of N8-GP During Prophylaxis (U/kg Per Month)	The mean consumption of N8-GP used for treatment of a bleed from start to stop of a bleed during prophylaxis (per month per subject). Consumption used for treatment includes all doses given (prophylaxis, treatment of bleed, minor surgery and pharmacokinetics [PK])	Main phase: (from 0-26 weeks of treatment) and full trial: (0 weeks to last patient's completion of the trial, an average of 4.5 years)
Secondary	Consumption of N8-GP During Prophylaxis (U/kg Per Year)	The mean consumption of N8-GP used for treatment of a bleed from start to stop of a bleed during prophylaxis (per year per subject). Consumption used for treatment includes all doses given (prophylaxis, treatment of bleed, minor surgery and pharmacokinetics)	Main phase: (from 0-26 weeks of treatment) and full trial: (0 weeks to last patient's completion of the trial, an average of 4.5 years)
Secondary	Incremental Recovery (Defined as the Peak Level Recorded 60 Min After End of Injection) Evaluated for Previous FVIII Product	The incremental recovery was defined as the increase in plasma FVIII activity per IU/kg of factor administered recorded 60 minutes after end of injection. It was calculated as (Factor VIII procoagulant [FVIII:C] activity measured in plasma 60 min after dosing - FVIII:C activity measured in plasma immediately before dosing) / (dose injected at time 0 min), where the dose was expressed as U FVIII product per kg body weight. A chromogenic assay with normal human plasma (NHP) as calibrator was used.	2-6 weeks prior to initial dosing with N8-GP and up to 30 hours after administration of previous FVIII product
Secondary	Incremental Recovery (Defined as the Peak Level Recorded 60 Min After End of Injection) Evaluated for N8-GP	The incremental recovery was defined as the peak level recorded 60 min after end of injection and dose-normalised. It was calculated as (FVIII:C activity measured in plasma 60 min after dosing - FVIII:C activity measured in plasma immediately before dosing) / (dose injected at time 0 min), where the dose was expressed as U FVIII product per kg body weight. A chromogenic assay with product specific calibrator (PSS) as calibrator was used.	From 1 hour prior to and up to 96 hours after initial administration of N8-GP
Secondary	Area Under the Curve Evaluated for Previous FVIII Product	Area under the curve (AUC) versus time from zero to infinity. This is calculated as AUC = AUClast + (C(t) / ?z), where C(t) is the last measurable concentration. A chromogenic assay with NHP as calibrator was used.	2-6 weeks prior to initial dosing with N8-GP and up to 30 hours after administration of previous FVIII product
Secondary	Area Under the Curve Evaluated for N8-GP	Area under the curve versus time from zero to infinity. This is calculated as AUC = AUClast + (C(t) / ?z), where C(t) is the last measurable concentration. A chromogenic assay with product specific standard (PSS) as calibrator was used.	From 1 hour prior to and up to 96 hours after initial administration of N8-GP
Secondary	Terminal Half-life Evaluated for Previous FVIII Product	t½ = ln(2) / ?z, where t½ is terminal half-life and ?z is the terminal elimination rate. The terminal elimination rate was planned estimated using linear regression on the terminal part of the time versus log(concentration) curve. A population-based method simultaneously estimating individual t½ values for all patients was applied, including patients with few values above the lower limit of quantification (LLOQ). This was estimated using time points from 1h to 30h. A chromogenic assay with PSS as calibrator was used.	2-6 weeks prior to initial dosing with N8-GP and up to 30 hours after administration of previous FVIII product
Secondary	Terminal Half-life Evaluated for N8-GP	t½ = ln(2) / ?z, where ?z is the terminal elimination rate. The terminal elimination rate was planned estimated using linear regression on the terminal part of the time versus log(concentration) curve. A population-based method simultaneously estimating individual t½ values for all patients was applied, including patients with few values above the LLOQ. This was estimated using time points from 6h to 96h. A chromogenic assay with PSS as calibrator was used.	From 1 hour prior to and up to 96 hours after initial administration of N8-GP
Secondary	Clearance Evaluated for Previous FVIII Product	Total plasma clearance of drug after intravenous administration measured as actual dose/AUC. A chromogenic assay with NHP as calibrator was used.	2-6 weeks prior to initial dosing with N8-GP and up to 30 hours after administration of previous FVIII product
Secondary	Clearance Evaluated for N8-GP	Total plasma clearance of drug after intravenous administration measured as actual dose/AUC. A chromogenic assay with PSS as calibrator was used.	From 1 hour prior to and up to 96 hours after initial administration of N8-GP.
