    Dosage and administration details
    There were two arms in the main phase – 1) Prophylaxis - Subjects received one single bolus dose of 50 IU/kg body weight (BW) of N8-GP every 4th day (96 hours interval). During treatment a shortening of the dosing interval for prophylaxis to twice weekly might be undertaken at the investigator’s discretion, if deemed necessary for the individual subject. Extra doses of N8-GP were administered, if the subject experienced a treatment-requiring bleeding episode or in case of minor surgery. 2) On-demand – Subjects received treatment with N8-GP if they experienced a treatment-requiring bleed. All bleeds were to be treated with doses between 20-75 IU/kg BW according to the severity and location of the bleeding episode. In both the arms, N8-GP was administered as a slow bolus i.v. injection over approximately 2 minutes (from start to completion of injection).

    There were three arms in the extension phase part-1: 1) N8-GP 50 IU/kg prophylaxis Q4D (once in 4 days) 2) N8-GP 75 IU/kg prophylaxis Q7D (once in 7 days) and 3) N8-GP 20-75 IU/kg on-demand. Subjects who were on N8-GP Q4D prophylaxis treatment in the main phase and had 0-2 bleeding episodes in last 6 months were randomised to receive N8-GP Q4D or Q7D in this period. Subjects with 3 or more bleeding episodes within the last 6 months of the main phase and subjects with low bleeding rates who were unwilling to be randomised continued with N8-GP Q4D. Subjects who received N8-GP on-demand treatment throughout the main phase continued with the on-demand regimen in the extension phase.

    There were three arms in the extension phase, part-1: 1) N8-GP 50 IU/kg prophylaxis Q4D- single bolus dose; 2) N8-GP 75 IU/kg prophylaxis Q7D – single bolus dose and 3) N8-GP 20-75 IU/kg on-demand. In the first 2 arms, extra doses of N8-GP were given if the subject had a treatment requiring bleeding episode or in case of a minor surgery. Based on bleeding pattern, the investigator could change the dosing frequency from Q7D to Q4D but changing from Q4D to Q7D was not permitted. Subjects on Q7D having 2 or more bleeding episodes or 1 episode requiring hospitalisation were shifted back to Q4D regimen. The trial product in all arms was to be administered as a slow bolus i.v. injection over approximately 2 minutes (from start to completion of injection).

In the first 2 arms, subjects could continue on the same prophylaxis dose as received in extension phase (part-1) but could change between Q4D and Q7D dosing. Subjects received treatment for up to approximately 1.5 years or until N8-GP became commercially available in the subject’s country. In the third arm, subjects who received N8-GP on-demand treatment throughout the main phase continued with the on-demand regimen in the extension phase part-2.

In the first 2 arms, extra doses of N8-GP were given if the subject had a treatment requiring bleeding episode or in case of a minor surgery. During this period, it was possible to change the prophylaxis treatment of subjects to Q4D or Q7D. Subjects with 0-2 bleeds in last 6 months could move to Q7D. Subjects on Q7D having 2 or more bleeding episodes were shifted back to Q4D regimen. The trial product in all arms was to be administered as a slow bolus i.v. injection over approximately 2 minutes (from start to completion of injection).

    Notes
    [5] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: Evaluation of ‘incidence rate of FVIII inhibitors ≥0.6 BU’ was based on descriptive statistics. Hence statistical analysis is not applicable for this endpoint.

    Annualised bleeding rate in the prophylaxis arm: At the end of treatment (EOT) visit [6]
    End point description
    Annualised bleeding rate (ABR) is the number of bleeding episodes per year reported during the prophylactic treatment with N8-GP. Results were based on the FAS which included all subjects exposed to N8-GP in this trial. Number of subjects analysed (n) = Number of subjects with available data for respective arm.

    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 subject and/or parent(s)/caregiver within approximately 8 hours after a single injection as follows: Excellent: Abrupt pain relief and/or clear improvement in objective signs of bleeding within approximately 8 hrs after a single injection; Good: Definite pain relief and/or improvement in signs of bleeding within approximately 8 hrs 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. Results were based on the FAS. 'Number of subjects analysed' should be read as 'Number of bleeds analysed'.

    Adverse events information
    Timeframe for reporting adverse events
    From first exposure to N8-GP (week 0) to follow up visit after end of treatment in extension phase part 2. (Main phase:19 months; Extension phase:approximately 2 years or until N8-GP becomes commercially available in the subject's country).
    Adverse event reporting additional description
    The results are based on the safety analysis set. 'Number of deaths causally related to treatment’ is the data considered to present under ‘total number of deaths resulting from adverse events (AE)’. All the presented AEs were treatment-emergent. A treatment-emergent AE was defined as an event with onset after first N8-GP administration.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    22 Dec 2011
    This global substantial amendment was issued primarily as a response to a voluntary harmonised procedure (VHP) assessment, which involve the clinical trial application (CTA) submission of the NN7088-3859 and NN7088- 3860 protocol in 8 European countries: VHP recommend a more detailed guidance on the treatment of bleeds. Therefore section 5.3.2 had been updated accordingly. VHP recommended a more clear guidance for the required observation period for adverse reactions in connection to administration of the two first doses of N8-GP. This had been added in the relevant sections. Anti-coagulants and heparin had been added in section 6.5 as prohibited medication to the protocols withdrawal criteria to make this more consistent.
    13 Apr 2012
    This global substantial protocol amendment was issued primarily as a response to a Special Protocol Assessment request sent to the US FDA in connection with submission of the NN7088-3859 protocol in the United States: 1) Annualised bleeding rate in prophylaxis arm. The calculation of annualised bleeding rate for withdrawals has been changed. Imputation will also be performed for withdrawals within the first month. An annualised bleeding rate of 24 will be used for imputation for all subjects withdrawing in the first month, including those with zero bleeds. 2) Sample size calculations have been changed. For the inhibitor test a true inhibitor rate of 0.5% instead of 1% is now assumed. This is based on the experience with clinical trials with turoctocog alfa. For the prophylaxis test, the impact on the power of the change in imputation rule for early withdrawals without bleeding episodes is accounted for. 3) An interim analysis has been added in order to evaluate the over-dispersion (only) once approximately 90 subjects have entered into the prophylaxis arm. If the estimated overdispersion is greater than 6 then the planned sample size will be adjusted up to include 160 prophylaxis subjects instead of 120 subjects. The planned sample size will not be increased without issuing a further amendment.
    21 Dec 2012
    This global substantial protocol amendment was issued in order to allow for an increase in sample size following the described interim analysis, should it be determined to be necessary.
    05 Apr 2013
    This global substantial amendment was issued in order to extend the maximum treatment period with 3 months, from 24 to 27 months, due to an extension of the recruitment period. Therefore additional visits 12a to visit 12j have been added. Subjects for the surgery trial, NN7088-3860, are recruited via this trial where they must have had at least 5 EDs before entering the surgery trial. This amendment will allow the continued recruitment of major surgery subjects after the recruitment of this trial has been completed. This is in order to ensure recruitment into the surgery trial and fulfilment of regulatory requirements regarding collection of major surgery data. The extension trial will not await these subjects to complete 50 EDs before it is initiated.
    04 Jul 2013
    This global amendment was issued to include the following: In version 6.0 of the NN7088-3859 protocol subjects could be transferred to the extension trial NN7088-3861 where they could continue treatment with N8-GP until it was commercially available. Instead of setting up a separate trial, the extension trial will be included in the current trial as an extension phase.
    17 Sep 2013
    This global amendment was issued primarily as a response to a VHP assessment, which involved a central EU CTA submission of the NN7088-3859 protocol version 7.0 in 8 European countries. Main changes were a description of rules for when a subject should be switched from Q7D to Q4D treatment regimen and deletion of every 5 and 6 day dosing regimens from the protocol.
    17 Sep 2013
    The VHP requested that subjects in the Q7D treatment arm receive the same visit schedule as subjects in the Q4D treatment arm of the main study phase i.e. monthly visits at the start of treatment, followed by visits every second month. In addition, it was agreed with the VHP to also implement this visit schedule for subjects randomised to Q4D in the extension phase part 1. This is to avoid any bias in the randomised arms. Part 1 of the extension is 6 months in duration, therefore monthly visits for the first 4 months have been introduced, followed by a visit 2 months later. The VHP stipulated that this visit schedule should apply for every switch to Q7D independent of the part of the extension phase. Therefore, this requirement has also been implemented for Q7D subjects in part 2 of the extension. In part 2, those switching to Q7D, will have visits every month for the first 4 months and subsequently every two months while on Q7D.
    23 Jan 2014
    The withdrawal criteria section 6.5 of the protocol was amended to allow subjects with a low titre inhibitor [≤5 Bethesda units (BU)], that does not result in clinically ineffective treatment with N8-GP, to continue in the trial. Text regarding adverse events was updated.
    19 Nov 2015
    This global amendment was issued to allow subjects to transfer to a separate pharmacokinetics (PK) trial NN7088-4033 and back again; to monitor antibody development against host cell protein; addition of interim analyses before submission; prolonged storage of leftover blood samples to enable further characterisation as new biomarkers related to the disease or related diseases and/or safety, efficacy or mechanism of action may evolve.
    21 Jun 2016
    The purpose of this amendment was to clarify when the subjects could complete the trial (to continue in another N8-GP trial, NN7088-4410).
