ListOutcomeTime frameDescription
PrimaryMean Annualized Bleed Rate (ABR) by Treatment: On Demand CohortDay 1 up to Month 6 (OD Cohort, OD Therapy, Period 1); Month 7 up to Month 18 (OD Cohort, RP 25 IU/kg, Period 2)
ABR for each participant was calculated as the number of bleeds requiring administration of moroctocog alfa (AF-CC) divided by the total therapy duration (in days), then multiplied by 365.25 (days in a year).
SecondaryMean Annualized Bleed Rate (ABR) by Treatment: Routine Prophylaxis CohortDay 1 up to Month 24 (RP Cohort, Period 1 and Period 2)
ABR for each participant was calculated as the number of bleeds requiring administration of moroctocog alfa (AF-CC) divided by the total therapy duration (in days), then multiplied by 365.25 (days in a year).
SecondaryMean of Moroctocog Alfa (AF-CC) Infusions Administered To Treat Bleeding Episode: All ParticipantsDay 1 up to Month 24
In this outcome measure, the mean of total number of moroctocog alfa (AF-CC) on-demand infusions administered to treat each bleeding episode was reported, regardless of participant cohort or period during which it occurred.
SecondaryNumber of Treated Bleeds Classified on Basis of Response to First Infusion of Moroctocog Alfa (AF-CC) as On-Demand Treatment: OD Therapy (OD and RP Cohort)Day 1 up to Month 24
Number (no.) of bleeds treated are reported on basis of response to first infusion of study drug, at 4-point scale: excellent, good, moderate, no response. Excellent:definite pain relief and/or improvement in bleeding signs within 8 hours (hr) after infusion, no additional infusion administered; Good:definite pain relief and/or improvement in bleeding signs within 8 hr after infusion, at least 1 additional infusion administered for complete resolution or with no additional infusion administered; Moderate:probable or slight improvement starting after 8 hr following infusion,at least 1 additional infusion administered for complete resolution; No Response: no improvement at all between infusions or during 24 hr interval following infusion or condition worsen. Bleeds for which response not recorded, reported as:Data Not Recorded. Total no. of first infusions may not be equal to total no. of bleeds if bleed was: missing start date/dose information or treated initially with non-study FVIII.
SecondaryNumber of Treated Spontaneous Bleeds by Time Interval Between Bleed Onset and Prior Moroctocog Alfa (AF-CC) Prophylaxis Dose: Routine Prophylaxis TherapyDay 1 up to Month 24 (RP Cohort, RP 25 IU/kg and 45 IU/kg, Period 1 and 2); Month 7 up to Month 18 (OD Cohort, RP 25 IU/kg, Period 2)
In this outcome measure number of treated spontaneous bleeds are reported according to the time interval between bleed onset and prior moroctocog alfa (AF-CC) routine prophylaxis dose. Following time intervals used to report this outcome measure: lesser than or equal to (\<=) 24 hours, greater than (\>) 24 hours to \<=48 hours, \>48 hours to \<=72 hours, \>72 hours. For reporting arm: "Moroctocog alfa (AF-CC),OD and RP Cohort: RP Therapy 25 IU/kg" cumulative data for routine prophylaxis cohort (Day 1 up to Month 24, Period 1 and Period 2) and on demand cohort (Month 7 up to Month 18, Period 2) is reported.
SecondaryNumber of Participants Requiring Prophylaxis Regimen Escalation: Routine Prophylaxis TherapyDay 1 up to Month 24 (RP Cohort, RP 25 IU/kg and 45 IU/kg, Period 1 and 2); Month 7 up to Month 18 (OD Cohort, RP 25 IU/kg, Period 2)
During prophylaxis, criteria for prophylaxis regimen escalation are the occurrence, over a 4-week duration (and in the absence of a confirmed FVIII inhibitor), of (a) 2 or more spontaneous bleeds into a major joint and/or target joint, or (b) 3 or more spontaneous bleeds (consisting of joint bleeds and/or significant soft tissue/muscle or other site bleeds). If either criterion was met, the participant was escalated to a more intense prophylaxis regimen of 45 IU/kg, administered every other day. Participant who meet dose escalation criteria while on prophylaxis regimen of 45 IU/kg, were escalated to a higher intensity regimen designated by the investigator. Significant spontaneous bleeds were those that led to a transient or persistent loss of function. For reporting arm: "Moroctocog alfa (AF-CC),OD and RP Cohort: RP Therapy 25 IU/kg", cumulative data for RP cohort (Day 1 up to Month 24, Period 1 and Period 2) and OD cohort (Month 7 up to Month 18, Period 2) is reported.
SecondaryMean Routine Prophylaxis Dose (IU/kg) of Moroctocog Alfa (AF-CC) Received: Routine Prophylaxis TherapyDay 1 up to Month 24 (RP Cohort, RP 25 IU/kg and 45 IU/kg, Period 1 and 2); Month 7 up to Month 18 (OD Cohort, RP 25 IU/kg, Period 2)
Mean RP dose (by weight) for each participant was calculated as his total moroctocog alfa (AF-CC) consumption (in IU) divided by weight (in kg). For reporting arm: "Moroctocog alfa (AF-CC),OD and RP Cohort: RP Therapy 25 IU/kg", cumulative data for routine prophylaxis cohort (Day 1 up to Month 24, Period 1 and Period 2) and on demand cohort (Month 7 up to Month 18, Period 2) is reported.
SecondaryMean of Total Number Moroctocog Alfa (AF-CC) Infusions Received: Routine Prophylaxis TherapyDay 1 up to Month 24 (RP Cohort, RP 25 IU/kg and 45 IU/kg, Period 1 and 2); Month 7 up to Month 18 (OD Cohort, RP 25 IU/kg, Period 2)
In this outcome measure mean of total number of infusions of moroctocog alfa (AF-CC) received by participant is reported. For reporting arm: "Moroctocog alfa (AF-CC),OD and RP Cohort: RP Therapy 25 IU/kg", cumulative data for routine prophylaxis cohort (Day 1 up to Month 24, Period 1 and Period 2) and on demand cohort (Month 7 up to Month 18, Period 2) is reported.
SecondaryMean of Total Number of Days Participants Exposed to Moroctocog Alfa (AF-CC): Routine Prophylaxis TherapyDay 1 up to Month 24 (RP Cohort, RP 25 IU/kg and 45 IU/kg, Period 1 and 2); Month 7 up to Month 18 (OD Cohort, RP 25 IU/kg, Period 2)
For reporting arm: "Moroctocog alfa (AF-CC),OD and RP Cohort: RP Therapy 25 IU/kg", cumulative data for routine prophylaxis cohort (Day 1 up to Month 24, Period 1 and Period 2) and on demand cohort (Month 7 up to Month 18, Period 2) is reported.
SecondaryMean of Total Number of Infusions of Moroctocog Alfa (AF-CC) Received Per Week to Assess Compliance: Routine Prophylaxis TherapyDay 1 up to Month 24 (RP Cohort, RP 25 IU/kg and 45 IU/kg, Period 1 and 2); Month 7 up to Month 18 (OD Cohort, RP 25 IU/kg, Period 2)
Participants' compliance to their assigned prophylaxis regimen was measured by following: a) number of infusions received per week and b) dose received. In this outcome measure mean of total number of infusions of moroctocog alfa (AF-CC) received by participants per week is reported. For reporting arm: "Moroctocog alfa (AF-CC),OD and RP Cohort: RP Therapy 25 IU/kg" cumulative data for routine prophylaxis cohort (Day 1 up to Month 24, Period 1 and Period 2) and on demand cohort (Month 7 up to Month 18, Period 2) is reported.
