Annualized bleed rates were transformed using the square root of the number of bleeding episodes observed (X bleeds/year), X' = √(X + 0.5). This transformation was performed to stabilize the variance and align the sample distribution with the assumption of normality inherent in using the t-test. The difference in mean transformed ABRs was used to perform statistical tests and generate p-values at a significance level of 5% Participants were Randomized to Receive 1 of the 2 Following Treatment Regimens: 1.On-Demand: FEIBA NF dose & dosing interval as prescribed by treating physician 2.Prophylaxis: 85 ± 15 U/kg of FEIBA NF every other day during 12-month prophylactic period

Annualized bleed rates (ABRs) were transformed using the square root of the number of bleeding episodes observed (X bleeds/year), X' = √(X + 0.5). This transformation was performed to stabilize the variance and align the sample distribution with the assumption of normality inherent in using a two-sample, two-sided t-test.

Pain caused by a bleeding episode in adolescents and adults (≥12 years old) was measured at pre-infusion (pre-inf) and at 6 ± 0.5 hours (h) and 24 ± 1 h post-infusion (post-inf) (after the last infusion given to treat a bleeding episode) on the VAS pain scale in millimeters from 0 (no pain) to 100 (worst possible pain). For analysis purposes, if short acting analgesics (duration of activity approximately 6 ± 0.5 h) were used, pain was assigned the highest possible score (100). Pain assessment occurred after each infusion related to single bleeding episodes. In case participants required an additional infusion within 24h, pain was assessed 6 ± 0.5 h and 24 ±1 h following the subsequent infusion. Change in VAS scores at 6 ± 0.5 h and 24 ±1 h post-infusion were also compared relative to pre-infusion VAS scores (ie, (pre-infusion VAS score) - (post-infusion VAS score)).

Additional evaluations for bleeding episodes in the intent-to-treat analysis dataset: consists of all participants with at least 1 bleeding episode treated with investigational product.

Pain caused by a bleeding episode (BE) in pediatric participants (<12 years old) was measured at pre-infusion (pre-inf) and at 6 ± 0.5 h and 24 ± 1 h post-infusion (post-inf) (after the last infusion given to treat a bleeding episode) using the children's VAS pain scale (a facial expression scale with one end marked as no pain and the opposite end marked as the worst possible pain). For analysis purposes, if short acting analgesics (duration of activity approximately 6 ± 0.5 h) were used, pain was assigned the highest possible score (worst possible pain). Scores on the children's VAS scale are presented as: -No Pain -Mild Pain -Moderate pain -Severe pain -Very severe pain

ROM was measured using a goniometer for 3 key joints (ie, ankles, knees, and elbows) at screening, month 6, and termination (end of study visit)

EQ-5D is a participant answered questionnaire scoring 5 dimensions - mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The EQ-5D total score ranges from 0 (worst health state) to 1 (perfect health state) and 1 reflects the best outcome. EQ-5D Index scores based on EQ-5D questionnaire were calculated for participants ≥14 years of age, at screening, 6 months, and at termination visit. Changes in scores at 6 months and termination were also calculated. A relatively higher score represents better quality of life.

The Haem-A-QoL instrument has been developed and used in Hemophilia A patients. As a hemophilia-specific instrument, this measure assesses very specific aspects of dealing with hemophilia. The areas covered by this instrument are: Physical Health (PH), Sports & Leisure (S&L), School & Work (W&S), Dealing with Hemophilia (Dealing), Family Planning (FP), Feeling, Relationships (R'ships), Treatment, View, and Outlook for the Future (Future). A Haem-A-QoL Total Score (Total) was also calculated. For the Haem-A-QoL, higher scores indicate a worse quality of life. Scores on a scale range between 0 and 100. Haem-A-QoL scores at screening, 6 months, and at termination visit were collected. Changes in scores at 6 months and termination were also calculated.

General pain was assessed using a VAS pain scale at screening, 6 months, and at termination. Unlike the VAS pain assessment for pain of bleeding episodes (Outcome above), this general pain assessment did not take use of analgesics into account. For the pain scale, a higher number indicates worse pain. The visual analog scale ranges from 0 to 100 where the endpoints are labeled 'Worst imaginable health state' (=0) and 'Best imaginable health state' (=100). A positive change from baseline indicates improvement. Change in VAS scores at 6 months and study termination were also compared relative to Baseline/Screening scores (ie, (Baseline/Screening VAS score) - (VAS score at 6 months and study termination).
