Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Bleeding Episode With "Treatment Success"	No additional hemostatic product required within 12 hours of first dose other than the prescribed dosing regimen.	within 12 hours of first dose
Secondary	Treatment Response for Each Bleeding Episode	Participants rated the treatment of each bleeding episode. If treatment occurred under direct supervision of treating physician, the physician rated the response. Ratings based on a 4 point scale; EXCELLENT - full relief of pain and cessation of objective signs of bleeding (swelling, tenderness, decrease in range of motion [for muscle bleeds]) within 9 hours of treatment initiation. No additional infusion required to control bleeding, other than prescribed dosing regimen. GOOD - Substantial relief of pain and/or cessation of objective signs of bleeding within 9 hours of treatment initiation. No additional infusion required to control bleeding, other than prescribed dosing regimen. MODERATE - slight relief of pain and slight improvement of signs of bleeding within 9 hours of treatment initiation. Requires additional infusion beyond treatment regimen. NONE - No improvement or condition worsens. SUCCESSFUL = EXCELLENT or GOOD.	within 24 hours of infusion
Secondary	Percentage of Clinical Responders (Sustained Bleeding Control) for All Acute Bleeding Episodes	Clinical responders defined as sustained bleeding control, (no additional hemostatic medication including rFVIIa BI required between 12 and 24 hours after first infusion of the successfully treated bleeding episode).	24 hours post infusion
Secondary	Safety and Tolerability of Treatment Regimens by Clinical Assessment of Percentage of Participants With Adverse Events (AEs)	Safety was determined by the number of AEs (both serious AEs [SAEs] and non-serious AEs [nsAE]). Tolerability was determined by the number of AEs related to rFVIIa BI (both SAEs and nsAEs) as determined by causality assessment of the AEs by the investigator. An AE was deemed Related if the investigator judged the AE to be "possibly related" or "probably related" to rFVIIa BI. The percentage of participants with AEs were presented by seriousness (SAE, nsAE), severity (Mild, Moderate or Severe) and causality (Related or Not Related to rFVIIa BI).	6 months (throughout study period)
Secondary	Safety and Tolerability of Treatment Regimens by Clinical Assessment of Adverse Events (AEs)	Safety was determined by the number of AEs (both serious AEs [SAEs] and non-serious AEs [nsAE]). Tolerability was determined by the number of AEs related to rFVIIa BI (both SAEs and nsAEs) as determined by causality assessment of the AEs by the investigator. An AE was deemed Related if the investigator judges the AE to be "possibly related" or "probably related" to rFVIIa BI. The percentage of AEs were presented by seriousness (SAE, nsAE), severity (Mild, Moderate or Severe) and causality (Related or Not Related [to rFVIIa BI]).	6 months (throughout study period)
Secondary	Percentage of Participants With Inhibitor Development to FVII	Development of rFVII inhibitors or FVIIa binding antibodies during the study.	6 months (throughout study period)
