Study Description

Brief Summary

This study will look at how a known study medicine N8-GP works in previously N8-GP treated people with haemophilia A. The aim is to look at how N8-GP works during regular use. Participants will get N8-GP. N8-GP has been tested in more than 200 people with haemophilia A for several years. Participants will get an injection of N8-GP into a blood vessel, one, two or three times weekly. Participants will get more doses if they bleed or if they will need a surgery. The study will last for about 2 years. Participants will have at least 9 visits with the study doctor. If participants agree to be in this study, they will get their first injection (in this study) at the first visit. Participants will also get an injection at visit 3, 5 and 7. Participants will be trained to give all other injections themselves. Participants must not use any clotting factors other than N8-GP or any anticoagulants (blood thinners) during the study.

Outcome Measures

Primary Outcome Measures

  1. Number of Adverse Events Reported [Week 0 to week 108]

    An adverse event (AE) was defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of a product, whether or not considered related to the product. All AEs mentioned here are treatment emergent adverse events (TEAEs). The TEAE is defined as an event reported from date of first trial product administration until end of the treatment visit (week 104) or follow-up visit if relevant (1 month after end of the treatment).

Secondary Outcome Measures

  1. Number of Participants With Inhibitory Antibodies Against Coagulation Factor VIII (FVIII) ≥0.6 Bethesda Units (BU) [Week 0 to week 104]

    The Incidence of inhibitors against coagulation factor eight (FVIII) is defined as titre greater than or equal to (≥) 0.6 Bethesda unit. The inhibitor antibodies were measured using a heat modified Nijmegen FVIII Bethesda assay. The number of participants who developed inhibitors against FVIII are reported.

  2. Number of Bleeding Episodes on Prophylaxis [Week 0 to week 104]

    Number of bleeding episodes per participant in the prophylaxis regimen was evaluated during 104 weeks.

  3. Number of Spontaneous Bleeding Episodes on Prophylaxis [Week 0 to week 104]

    Spontaneous bleeding referred as bleeding episodes that occurred without apparent cause. The number of spontaneous bleeding episodes were evaluated during 104 weeks.

  4. Haemostatic Effect of N8-GP When Used for Treatment of Bleeding Episodes Assessed as: Excellent, Good, Moderate, or None [Week 0 to week 104]

    The haemostatic effect after treatment of a bleed with N8-GP was assessed using a 4-point scale: 'excellent', 'good', 'moderate' or 'none'. The evaluation was done as follows: 1. Excellent: Abrupt pain relief and/or unequivocal improvement in objective signs of bleeding within approximately 8 hours after a single injection. 2. Good: Definite pain relief and/or improvement in signs of bleeding within approximately 8 hours after an injection, but possibly requiring more than one injection for complete resolution. 3. Moderate: Probable or slight beneficial effect within approximately 8 hours after the first injection; usually requiring more than one injection 4. None: No improvement or worsening of symptoms.

  5. Mean Number of N8-GP Injections Required Per Bleeding Episode [Week 0 to week 104]

    The mean number of N8-GP injections required per bleeding episode from start to stop of a bleed for participants was presented from week 0 to week 104.

  6. Pre-dose FVIII Activity Levels on N8-GP Prophylaxis [Week 0 to week 104]

    The pre-dose FVIII activity levels were assessed in International units per millilitre (IU/mL) units from week 0 to week 104 to get an estimate of the pre-dose level for N8-GP at steady-state using mixed model.

  7. Change in Joint Health Status From Start to End of Trial (Based on Haemophilia Joint Health Score) [Week 0, Week 104]

    Haemophilia Joint Health Score is a validated outcome tool developed for the assessment of joint health in patients with hemophilia. It comprises an evaluation of the elbow, knee and ankle joints with regards to swelling, muscular atrophy, crepitation and range of motion, joint pain, strength, motion and axial alignment. The score range is from 0 to 24 points (a score of 0 indicates no joint damage. Higher the score higher the joint damage). Change from week 0 to end of trial (week 104) in the domain scores was presented.

  8. Haemostatic Response During Major Surgical Interventions Assessed as: Excellent, Good, Moderate, or None [Week 0 to week 104]

    The Haemostatic response to N8-GP during major surgical interventions was assessed using a 4-point scale: 'excellent', 'good', 'moderate' or 'none'. The evaluation was done as follows: 1. Excellent: Better than expected/predicted in this type of procedure. 2. Good: As expected in this type of procedure 3. Moderate: Less than optimal for the type of procedure but haemostatic response maintained without change of treatment regimen 4. None: Bleeding due to inadequate therapeutic response with adequate dosing, change of regimen required. This endpoint was measured from week 0 to week 104.

  9. Consumption of N8-GP Per Bleed [Week 0 to week 104]

    The average dose of N8-GP consumed for treatment of bleed was assessed in International units per kilogram per bleed(IU/kg/bleed). This endpoint was evaluated from week 0 to week 104.

  10. Consumption of N8-GP During Prophylaxis Treatment [Week 0 to week 104]

    The average dose of N8-GP consumed for prevention of bleed was assessed. This endpoint was evaluated from week 0 to week 104.

  11. Change From Start Till End of Trial in Treatment Satisfaction (Based on Hemo-SAT Score) [Week 0, Week 104]

    The treatment satisfaction of a bleed with N8-GP was assessed using HEMO-SAT assessment tool which contains a questionnaire with 6 domains (Ease and convenience, efficacy, burden, specialist/nurses, centre/hospital, general satisfaction), with a scale of 0-100. The lower scores reflecting greater treatment satisfaction. In other words, decrease in the score would mean improvement. The summary of change presented was based on individual changes since week 0. Data is presented for total score.

Pre-assignment Detail Out of 160 participants enrolled in this study, 102 came from trial NN7088-3859 and 58 came from trial NN7088-3885. The participants received turoctocog alfa pegol (N8-GP) injections either as once-weekly, twice weekly or three times weekly during the 104 weeks treatment period. Despite 160 participants started the trial, the total number of participants considered are 167 as 2 participants switched to twice weekly and 5 participants switched to three times weekly regimen.
Arm/Group Title N8-GP, Once Weekly N8-GP, Twice Weekly N8-GP, Three Times Weekly
Arm/Group Description Participants received once weekly (dosing every 7 day) prophylaxis doses of N8-GP, 75 IU/kg (International Units per kilogram) intravenous injections for 104 weeks. Participants treated with N8-GP once weekly or were on the on demand regimen in the previous trial NN7088-3859 (pathfinder2) were included in this arm. At the investigator's discretion an intensification of the dosing regimen to twice weekly was allowed if the participant experienced more than 2 bleeds within an 8 week period or experienced a severe bleed requiring hospitalization. Participants received twice weekly (dosing every 3 and 4 days) prophylaxis doses of N8-GP intravenous injections for 104 weeks: N8-GP, 50 IU/kg for participants aged ≥ 12 years and N8-GP, 60 IU/kg for participants aged < 12 years. Participants treated with N8-GP in the previous trials NN7088-3859 (pathfinder2) and NN7088-3885 (pathfinder5) were included in this arm. At the investigator's discretion, an intensification of the dosing regimen to thrice weekly was allowed if the participant experienced spontaneous bleeding episodes. Participants in this arm were permitted to switch to three times weekly at any time if clinically justified. Otherwise any treatment regimen was preferably be kept for a minimum of 6 months. Participants received three times weekly (dosing every 2, 2 and 3 days) prophylaxis doses of N8-GP, 50 IU/kg as intravenous injections for a duration of 104 weeks. Participants treated with N8-GP in the previous trials NN7088-3859 (pathfinder2) and NN7088-3885 (pathfinder5) were included in this arm.

Arm/Group Title N8-GP, Once Weekly N8-GP, Twice Weekly N8-GP, Three Times Weekly
Arm/Group Description Participants received once weekly (dosing every 7 day) prophylaxis doses of N8-GP, 75 IU/kg (International Units per kilogram) intravenous injections for 104 weeks. Participants treated with N8-GP once weekly or were on the on demand regimen in the previous trial NN7088-3859 (pathfinder2) were included in this arm. At the investigator's discretion an intensification of the dosing regimen to twice weekly was allowed if the participant experienced more than 2 bleeds within an 8 week period or experienced a severe bleed requiring hospitalization. Participants received twice weekly (dosing every 3 and 4 days) prophylaxis doses of N8-GP intravenous injections for 104 weeks: N8-GP, 50 IU/kg for participants aged ≥ 12 years and N8-GP, 60 IU/kg for participants aged < 12 years. Participants treated with N8-GP in the previous trials NN7088-3859 (pathfinder2) and NN7088-3885 (pathfinder5) were included in this arm. At the investigator's discretion, an intensification of the dosing regimen to thrice weekly was allowed if the participant experienced spontaneous bleeding episodes. Participants in this arm were permitted to switch to three times weekly at any time if clinically justified. Otherwise any treatment regimen was preferably be kept for a minimum of 6 months. During the trial, 2 participants switched from once weekly to twice weekly regimen for treatment intensification. Thus, though 133 participants have started the trial with twice weekly regimen, the data is presented for 135 participants in this arm (i.e. 133+2 = 135). Participants received three times weekly (dosing every 2, 2 and 3 days) prophylaxis doses of N8-GP, 50 IU/kg as intravenous injections for a duration of 104 weeks. Participants treated with N8-GP in the previous trials NN7088-3859 (pathfinder2) and NN7088-3885 (pathfinder5) were included in this arm. Participants in this arm were permitted to switch to twice weekly at any time if clinically justified. Otherwise any treatment regimen was preferably be kept for a minimum of 6 months. During the trial, 5 participants switched from twice weekly to three times weekly regimen for treatment intensification. Thus, though 2 participants have started the trial with three times regimen, the data is presented for 7 participants in this arm (i.e. 2+5 = 7).

At the investigator's discretion an intensification of the dosing regimen to twice weekly was allowed if the participant experienced more than 2 bleeds within an 8 week period or experienced a severe bleed requiring hospitalization. Participants received twice weekly (dosing every 3 and 4 days) prophylaxis doses of N8-GP intravenous injections for 104 weeks: N8-GP, 50 IU/kg for participants aged ≥ 12 years and N8-GP, 60 IU/kg for participants aged < 12 years. Participants treated with N8-GP in the previous trials NN7088-3859 (pathfinder2) and NN7088-3885 (pathfinder5) were included in this arm. At the investigator's discretion, an intensification of the dosing regimen to thrice weekly was allowed if the participant experienced spontaneous bleeding episodes. Participants in this arm were permitted to switch to three times weekly at any time if clinically justified. Otherwise any treatment regimen was preferably be kept for a minimum of 6 months. During the trial, 2 participants switched from once weekly to twice weekly regimen for treatment intensification. Thus, though 133 participants have started the trial with twice weekly regimen, AE data is presented for 135 participants in this arm (i.e. 133+2 = 135). Participants received three times weekly (dosing every 2, 2 and 3 days) prophylaxis doses of N8-GP, 50 IU/kg as intravenous injections for a duration of 104 weeks. Participants treated with N8-GP in the previous trials NN7088-3859 (pathfinder2) and NN7088-3885 (pathfinder5) were included in this arm. Participants in this arm were permitted to switch to twice weekly at any time if clinically justified. Otherwise any treatment regimen was preferably be kept for a minimum of 6 months. During the trial, 5 participants switched from twice weekly to three times weekly regimen for treatment intensification. Thus, though 2 participants have started the trial with three times regimen, AE data is presented for 7 participants in this arm (i.e. 2+5 = 7). Total number of participants
