Number of Treated Spontaneous Bleeds by Time Interval Between Bleed Onset and Prior Moroctocog Alfa (AF-CC) Prophylaxis Dose: Routine Prophylaxis Therapy

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.

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.

Number of Participants Requiring Prophylaxis Regimen Escalation: Routine Prophylaxis Therapy

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.

Time frame: Day 1 up to Month 25

Number of Participants With Treatment-Related Adverse Events

A treatment related AE is any untoward medical occurrence in a clinical investigation participant administered a product or medical device; the event had a causal relationship with the treatment or usage. All participants in the study received moroctocog alfa-(AF-CC). Adverse events were not collected separately for each intervention for the participants. All participants were properly combined for the analysis and was regardless of the regimen they were following at the time, and regardless of OD or RP cohort.

Time frame: Day 1 up to Month 25

Number of Participants With Confirmed FVIII Inhibitor Development

Confirmed FVIII inhibitors were defined as a neutralizing antibody to FVIII with a titer value of greater than or equal to (\>=) 0.6 Bethesda units (BU) per millimeter in a sample assayed using the Nijmegen assay at the central laboratory.

Time frame: Day 1 up to Month 24

Number of Participants With Incidence of Less Than Expected Therapeutic Effect (LETE): On Demand Therapy

LETE occurs in OD setting if participant recorded 2 successive "No Response" (no improvement at all between infusions, or condition worsens) ratings after 2 successive infusions of study drug. Infusions must have been given within 24 hours (hr) of each other for treatment of same bleeding event in absence of confounding factors (known presence or subsequent identification of a FVIII inhibitor, known inadequate dose for type and/or severity of bleed in opinion of investigator, delay of \>4 hr between onset of bleed to infusion, delay of \>24 hr before administration of a follow-up infusion, known compromised study drug, faulty administration of study drug, participant had an underlying, predisposing condition responsible for bleed in opinion of investigator. 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.

Number of Participants With Incidence of Less Than Expected Therapeutic Effect (LETE): Routine Prophylaxis Therapy

LETE in prophylaxis setting if there was a spontaneous bleed within 48 hours after a regularly scheduled prophylactic dose of study drug (which was not used to treat a bleed) in the absence of confounding factors (known presence or subsequent identification of a FVIII inhibitor, known inadequate prophylactic dose \[a dose less than that prescribed in participant's regimen\], known lack of adherence to the prescribed prophylaxis regimen, bleed occurs in a target joint identified at the start of the study, known compromised study drug, faulty administration of study drug, participant had an underlying, predisposing condition responsible for the bleed in the opinion of the investigator. Therefore, LETE in the prophylaxis setting was the occurrence of a bleed. 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.
