Recruitment Details | The trial was conducted at 66 sites in 25 countries: Australia(2), Brazil(1), Canada(1), Croatia(1), Denmark(1), France(2), Germany(2), Greece(1), Hungary(2), Israel(1), Italy(2), Japan(3), Korea(1), Lithuania(1), Malaysia(1), Netherlands(2), Norway(1), Portugal(1), Spain(2), Switzerland(4), Taiwan(1), Turkey(5), Ukraine(1), United Kingdom (8), United States (USA) (19). |
Pre-assignment Details | 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. |

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. 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. |
