Participant Flow

The trial was conducted at 29 sites in 11 countries as follows (number of sites that screened participants/ number of sites that randomised participants): Australia (1/1); Austria (2/2); Canada (1/1); Israel (1/1); Japan (1/1); Malaysia (4/4); Spain (3/3); Taiwan (2/2); Thailand (2/2); United Kingdom (3/3); United States (9/9).

Trial consists of main phase including pre-prophylaxis \& prophylaxis, extension phase \& prophylaxis period until end of treatment. Pre-prophylaxis was optional and allowed participants to receive treatment until 24 months of age/upon reaching 20EDs, whichever came first. Other participants directly started on prophylaxis treatment at visit 1.

Measure
Pre-prophylaxis
Participants received nonacog beta pegol 40 international units/kilogram (IU/kg) intravenous injection at intervals longer than a week on-demand for bleeding episodes until they were 24 months of age or until 20 exposure days (ED), whichever came first, in the main phase. Participants switched from pre-prophylaxis treatment to prophylaxis treatment no later than 24 months of age/20 ED, whichever came first.
Prophylaxis
Participants who started with pre-prophylaxis were switched to prophylaxis no later than 24 months of age or upon reaching 20EDs, whichever came first. These participants that switched from pre-prophylaxis and other participants who started directly on prophylaxis since visit 1 received once weekly dosing of nonacog beta pegol 40 IU/kg intravenous injection in the main phase, extension phase, and until the end of treatment.

Haemostatic effect of nonacog beta pegol in treatment of bleeding episodes by 4-point haemostatic response scale after 50 ED, after 100 ED, and at end of trial is presented. The haemostatic response after treatment of a bleed with nonacog beta pegol was evaluated on a 4-point scale as excellent, good, moderate or poor. Excellent: abrupt pain relief and/or clear improvement in objective signs of bleeding; Good: noticeable pain relief and/or improvement in signs of bleeding; Moderate: probable or slight beneficial effect after the first injection; Poor: no improvement or worsening of symptoms. If the haemostatic response was rated as excellent or good, the treatment of the bleed was considered a success. If the haemostatic response was rated as moderate or poor, the treatment was considered a failure.

Incremental recovery 30 minutes post dosing (IR30min) after 50 ED, after 100 ED is presented. IR30min was defined as the rise in FIX activity per international units per kilogram (IU/kg) administered and was recorded 30 minutes after the end of nonacog beta pegol injection. It was calculated as the baseline adjusted FIX activity recorded 30 minutes after ended nonacog beta pegol injection divided by the administered dose (IU/kg body weight). It was recorded as international units per milliliter (IU/mL)/international units per kilogram (IU/kg).

n=25 Participants
Participants received nonacog beta pegol 40 international units/kilogram (IU/kg) intravenous injection at intervals longer than a week on-demand for bleeding episodes until they were 24 months of age or until 20 exposure days (ED), whichever came first, in the main phase. Participants switched from pre-prophylaxis treatment to prophylaxis treatment no later than 24 months of age/20 ED, whichever came first.
Prophylaxis
Participants who started with pre-prophylaxis were switched to prophylaxis no later than 24 months of age or upon reaching 20EDs, whichever came first. These participants that switched from pre-prophylaxis and other participants who started directly on prophylaxis since visit 1 received once weekly dosing of nonacog beta pegol 40 IU/kg intravenous injection in the main phase, extension phase, and until the end of treatment.

Population: Full analysis set included all participants exposed to nonacog beta pegol. Overall Number of Participants Analyzed = participants with available data for this outcome measure.

FIX Activity 30 minutes post dosing (C30min) after 50 ED, after 100 ED is presented. The FIX activity was measured by one-stage clotting assay - a modified activated partial thromboplastin time (aPTT) assay.

FIX trough levels after 50 ED, after 100 ED, and at end of trial is presented. FIX trough level was defined as the activity recorded immediately before nonacog beta pegol injection was given and was measured by one-stage clotting assay - a modified activated partial thromboplastin time (aPTT) assay. The analysis is based on a mixed model on the log-transformed plasma concentrations with participant as a random effect. The mean trough level is presented back-transformed to the natural scale.
