Brief Summary

This study was conducted in Africa, Europe, the Middle-East and South America. The primary objective of this registry was to observe the use of single dose and multi-dose use of activated recombinant human factor VII and to compare short-term outcomes, including effectiveness, safety, quality of life and treatment satisfaction with the approved treatments.

Primary Outcome Measures
NameTimeMethod
Percentage of Bleed Treatments Resulting in Effective Bleed Resolution (Spontaneous Bleed Episodes)within 9 hours of first injection

The percentage of bleed treatments successfully resulting in bleed resolution. Analysis only considers the patient's opinion of effectiveness at 9 hours, with a rating of "Effective" considered as successful treatment.

Percentage of Bleed Treatments Resulting in Effective Bleed Resolution (All Bleed Episodes)within 9 hours of first injection

The percentage of bleed treatments successfully resulting in bleed resolution. Analysis only considers the patient's opinion of effectiveness at 9 hours, with a rating of "Effective" considered as successful treatment.

Percentage of Bleed Treatments Resulting in Effective Pain Relief (All Bleed Episodes)within 9 hours of first injection

The percentage of participants with effective pain relief. Pain relief was a subjective assessment made by the patient during treatment of a bleed episode.

Percentage of Bleed Treatments Resulting in Effective Pain Relief (Spontaneous Bleed Episodes)within 9 hours of first injection

The percentage of participants with effective pain relief. Pain relief was a subjective assessment made by the patient during treatment of a bleed episode.

Secondary Outcome Measures
NameTimeMethod
Total Number of Injections (Spontaneous Bleed Episodes)individual bleed episode

The median number of injections required to treat individual bleed episodes.

Percentage of Bleed Treatments Resulting in Effective Pain Relief by Time Point (Spontaneous Bleed Episodes)1 hour, 3 hours and 6 hours, respectively, after first injection

Effective pain relief at 3 different time points for spontaneous bleeds. Patient reported outcomes are reported over 1 hour, 3 hours and 6 hours.

Total Number of Injections (All Bleed Episodes)individual bleed episode

The median number of injections required to treat individual bleed episodes.

Percentage of Bleed Treatments Resulting in Patient Satisfaction With Symptom Relief (Spontaneous Bleed Episodes)duration of bleed episode

Patient rate of satisfaction with symptom relief for the bleed episode overall on a 7-point Likert scale. Completion of questionnaire was voluntary. A Likert scale is an ordered, multiple choice questionnaire from which respondents choose one option that best aligns with their view of the particular outcome being measured. Scale answers ranged from extremely satisfied to extremely dissatisfied. The percentage of bleed episodes for which patients reported "extremely satisfied", "very satisfied" or "satisfied" is presented.

Overall Time to Cessation of Bleed/Achievement of Haemostasis (Spontaneous Bleed Episodes)duration of bleed episode

Median time to achievement of haemostasis/bleed cessation calculated using Kaplan Meier life table methods. If approximately 50% or less of bleeds achieved the endpoint in a given initial dose subgroup, the median cannot be calculated and it is reported as not applicable

Overall Time to Cessation/Achievement of Haemostasis (Spontaneous Bleed Episodes)duration of bleed episode

Median time to achievement of haemostasis/bleed cessation calculated using Kaplan Meier life table methods. If approximately 50% or less of bleeds achieved the endpoint in a given initial dose subgroup, the median cannot be calculated and it is reported as not applicable.

Childrens' Health Related Quality of Life (Haemo-QoL): Overall ScoreBaseline (week 0) and and registry discontinuation (up to 28 months)

The Haemo-QoL is a specific multidimensional validated and reliable questionnaire used to assess quality of life in patients with haemophilia. Scores are reported on a 0 to 100 scale-higher scores indicate more impairment.

Percentage of Bleed Treatments Resulting in Effective Haemostasis (Cessation of Bleeds) by Time Point (All Bleed Episodes)1 hour, 3 hours and 6 hours, respectively, after first injection

Effective haemostasis at 3 different time points for all bleeds. Patient reported outcomes are reported over 1 hour, 3 hours and 6 hours.

Percentage of Bleed Treatments Resulting in Effective Pain Relief by Time Point (All Bleed Episodes)1 hour, 3 hours and 6 hours, respectively, after first injection

Effective pain relief at 3 different time points for all bleeds. Patient reported outcomes are reported over 1 hour, 3 hours and 6 hours.

Total Exposure (Cumulative Dose) to Activated Recombinant Human Factor VII (All Bleed Episodes)individual bleed episode

The median total cumulative dose required to treat individual bleed episodes.

Percentage of Bleed Treatments Resulting in Effective Haemostasis (Cessation of Bleeds) by Time Point (Spontaneous Bleed Episodes)1 hour, 3 hours and 6 hours, respectively, after first injection

Effective haemostasis at 3 different time points for all bleeds. Patient reported outcomes are reported over 1 hour, 3 hours and 6 hours.

Percentage of Bleed Treatments Resulting in Patient Satisfaction With Ease of Use (Spontaneous Bleed Episodes)duration of bleed episode

Rate of ease of use related to activated recombinant human factor VII on a 7-point Likert scale. Completion of questionnaire was voluntary. A Likert scale is an ordered, multiple choice questionnaire from which respondents choose one option that best aligns with their view of the particular outcome being measured. Scale answers ranged from extremely difficult to extremely easy. The percentage of bleed episodes for which patients reported "extremely easy", "very easy" or "easy" is presented.

Overall Time to Cessation of Bleed/Achievement of Haemostasis (All Bleed Episodes)duration of bleed episode

Median time to achievement of haemostasis/bleed cessation calculated using Kaplan Meier life table methods. If approximately 50% or less of bleeds achieved the endpoint in a given initial dose subgroup, the median cannot be calculated and it is reported as not applicable

Total Exposure (Cumulative Dose) to Activated Recombinant Human Factor VII (Spontaneous Bleed Episodes)individual bleed episode

The median total cumulative dose required to treat individual bleed episodes.

Percentage of Patients Reporting Satisfaction With Symptom Relief (All Bleed Episodes)duration of bleed episode

Patient rate of satisfaction with symptom relief for the bleed episode overall on a 7-point Likert scale. Completion of questionnaire was voluntary. A Likert scale is an ordered, multiple choice questionnaire from which respondents choose one option that best aligns with their view of the particular outcome being measured. Scale answers ranged from extremely satisfied to extremely dissatisfied. The percentage of bleed episodes for which patients reported "extremely satisfied", "very satisfied" or "satisfied" is presented.

Percentage of Bleed Treatments Resulting in Patient Satisfaction With Ease of Use (All Bleed Episodes)duration of bleed episode

Rate of ease of use related to activated recombinant human factor VII on a 7-point Likert scale. Completion of questionnaire was voluntary. A Likert scale is an ordered, multiple choice questionnaire from which respondents choose one option that best aligns with their view of the particular outcome being measured. Scale answers ranged from extremely difficult to extremely easy. The percentage of bleed episodes for which patients reported "extremely easy", "very easy" or "easy" is presented.

Adults' Health Related Quality of Life (Haemo-QoL-A): Overall ScoreBaseline (week 0) and and registry discontinuation (up to 28 months)

The adult Haemo-QoL-A is a specific multidimensional validated and reliable questionnaire used to assess quality of life in patients with haemophilia. Scores are reported on a 0 to 100 scale-higher scores indicate more impairment.
