Outcome Measures
Primary Outcome Measures
- Overall Summary of the Number of Participants With Adverse Events, Severity Assessed According to the World Health Organization (WHO) Toxicity Grading Scale [From Baseline until study completion (up to 2 years)]
Investigators sought information on adverse events (AEs) at each contact with participants. The WHO toxicity grading scale was used for assessing AE severity (i.e., intensity of an AE); any AEs not specifically listed in the WHO toxicity grading scale were assessed for severity according to the following grades: Grade 1 is mild; Grade 2 is moderate, Grade 3 is severe; Grade 4 is life-threatening; and Grade 5 is death. Regardless of severity, some AEs may have also met seriousness criteria. The terms "severe" and "serious" are not synonymous; severity and seriousness were independently assessed for each AE. aPCC = activated prothrombin complex concentrate
- Adverse Events (AEs) Rates Per 100 Patient-Years for All-Grade AEs, Serious AEs, and Grade ≥3 AEs [From Baseline until study completion (up to 2 years)]
Investigators sought information on adverse events (AEs) at each contact with participants. The WHO toxicity grading scale was used for assessing AE severity (i.e., intensity of an AE); any AEs not specifically listed in the WHO toxicity grading scale were assessed for severity according to the following grades: Grade 1 is mild; Grade 2 is moderate, Grade 3 is severe; Grade 4 is life-threatening; and Grade 5 is death. Regardless of severity, some AEs may have also met seriousness criteria. The terms "severe" and "serious" are not synonymous; severity and seriousness were independently assessed for each AE. The AE rate per 100 patient-years was computed as follows: AE Rate = (Number of AEs observed/ Total patient-years at risk)*100. Total patient-years at risk is the sum over all patients of the time intervals (in years) between start of study therapy (study day 1) and the end of follow up.
- Number of Participants by Hematology and Biochemistry Laboratory Parameter Test Results as Shifts From the WHO Toxicity Grade at Baseline to the Worst WHO Toxicity Grade Post-Baseline [Baseline, Weeks 2, 3, and 5; Months 3, 6, 9, 12, and 18; and at Early Termination/Study Completion (up to 24 months)]
The World Health Organization (WHO) toxicity grading scale was used for determining the severity of laboratory abnormalities (i.e., test results outside of the reference range) for hematology and biochemistry parameters; Grade 0 is normal and Grades 1 to 4 represent worsening levels of the parameter outside of the normal range in the specified direction of the abnormality (high and low are above and below the range, respectively). Not every laboratory abnormality qualified as an adverse event (AE). A laboratory test result was reported as an AE if it met any of the following criteria: was accompanied by clinical symptoms; resulted in a change in study treatment; resulted in a medical intervention or a change in concomitant therapy; or was clinically significant in the investigator's judgment. Baseline was defined as the last available assessment prior to first receipt of study drug. Abs = absolute count; SGOT/AST = aspartate aminotransferase; SGPT/ALT = alanine aminotransferase

The number of bleeds over the efficacy period was analyzed as an ABR using a negative binomial regression model. Treated bleeds: bleeds followed by a hemophilia medication reported to be a "Treatment for bleed". All bleeds: included both treated and non-treated bleeds. Treated joint bleeds: treated bleeds where bleed type was "joint bleed" accompanied by at least one of following symptoms: "increased swelling or warmth of the skin over the joint", "increasing pain" or "decreased range of motion or difficulty using the joint compared with baseline". Treated target joint bleeds: treated joint bleeds that occurred in a target joint, defined as a joint in which ≥3 treated joint bleeds occurred during the 24 weeks prior to study entry. Treated spontaneous bleeds: treated bleeds with no other known contributing factor such as trauma or procedure/surgery. For all bleed types, bleeds due to surgery/procedure were excluded. Bleeds occurring after dose up-titration have been excluded.

The EQ-5D-5L is a generic, self-reported, preference-based health utility measure that consists of six questions and is used to assess health status and inform pharmacoeconomic evaluations. The index utility score is based on the participant's assessment of their health on five scales: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. It ranges from -0.224 to 1, with 0 corresponding to death and 1 corresponding to full health; negative values correspond to health states worse than death. Higher scores indicate better quality of life.
- Change From Baseline in the EuroQoL Five-Dimension-Five Levels Questionnaire (EQ-5D-5L) Quality-of-Life Visual Analogue Scale (VAS) Score at Specified Timepoints [Baseline (Week 1), 3, 6, 12, and 18 months, and at Early Termination or Study Completion (up to 24 months)]
The EQ-5D-5L is a generic, self-reported, preference-based health utility measure that consists of six questions and is used to assess health status and inform pharmacoeconomic evaluations. The visual analogue scale (VAS) ranges from 0 to 100 points, on which the participant self-assesses their current health status; 0 being the worst health you can imagine and 100 being the best health you can imagine. Higher scores are reflective of better health.
- Percentage of Participants Who Preferred the New Emicizumab Treatment or the Old Hemophilia Treatment, or Without Treatment Preference, as Assessed by the EmiPref Questionnaire [Month 3]
The EmiPref questionnaire asked participants to specify the treatment they would prefer to continue to receive after receiving treatment with their previous episodic or prophylactic regimen and subcutaneous (SC) emicizumab, or if they had no preference. The 95% confidence intervals were calculated for one sample binomial using the Pearson-Clopper method.
- Number and Percentage of Participants With Anti-Drug Antibodies (ADAs) Against Emicizumab at Anytime Post-Baseline [Baseline (Week 1), Week 5, and at 3, 6, 9, 12, and 18 months, and at early termination/study completion (up to 24 months)]
'Total ADA Negative' is the sum of all subjects who tested negative for ADA in the 2 following categories: 'ADA Negative', those who are pre-dose ADA negative or are missing pre-dose ADA data and who have all negative post-dose ADA results; and 'ADA Negative (Treatment Unaffected)', a subset who are pre-dose ADA positive but do not have a ≥4-fold increase in post-dose ADA levels compared to baseline measurement. 'Total ADA Positive' is the sum of all subjects who tested positive for ADA in the 2 following categories: 'ADA Positive (Treatment Boosted)', those who are pre-dose ADA positive and have a ≥4-fold increase in post-dose ADA levels compared to baseline measurement; and 'ADA Positive (Treatment Induced)', those who are pre-dose ADA negative or missing data and who have at least one post-dose ADA positive sample.
- Mean Trough Plasma Concentrations of Emicizumab at Specified Timepoints [Pre-dose at Weeks 2, 3, and 5, Months 3, 6, 12, and 18, and at treatment discontinuation (up to 2 years)]
The trough concentration is a measure of the plasma concentration of a study drug at the end of of the dosage interval.

Outcome Measures
Title | Overall Summary of the Number of Participants With Adverse Events, Severity Assessed According to the World Health Organization (WHO) Toxicity Grading Scale |
---|---|
Description | Investigators sought information on adverse events (AEs) at each contact with participants. The WHO toxicity grading scale was used for assessing AE severity (i.e., intensity of an AE); any AEs not specifically listed in the WHO toxicity grading scale were assessed for severity according to the following grades: Grade 1 is mild; Grade 2 is moderate, Grade 3 is severe; Grade 4 is life-threatening; and Grade 5 is death. Regardless of severity, some AEs may have also met seriousness criteria. The terms "severe" and "serious" are not synonymous; severity and seriousness were independently assessed for each AE. aPCC = activated prothrombin complex concentrate |

Title | Adverse Events (AEs) Rates Per 100 Patient-Years for All-Grade AEs, Serious AEs, and Grade ≥3 AEs |
---|---|
Description | Investigators sought information on adverse events (AEs) at each contact with participants. The WHO toxicity grading scale was used for assessing AE severity (i.e., intensity of an AE); any AEs not specifically listed in the WHO toxicity grading scale were assessed for severity according to the following grades: Grade 1 is mild; Grade 2 is moderate, Grade 3 is severe; Grade 4 is life-threatening; and Grade 5 is death. Regardless of severity, some AEs may have also met seriousness criteria. The terms "severe" and "serious" are not synonymous; severity and seriousness were independently assessed for each AE. The AE rate per 100 patient-years was computed as follows: AE Rate = (Number of AEs observed/ Total patient-years at risk)*100. Total patient-years at risk is the sum over all patients of the time intervals (in years) between start of study therapy (study day 1) and the end of follow up. |

Title | Number of Participants by Hematology and Biochemistry Laboratory Parameter Test Results as Shifts From the WHO Toxicity Grade at Baseline to the Worst WHO Toxicity Grade Post-Baseline |
---|---|
Description | The World Health Organization (WHO) toxicity grading scale was used for determining the severity of laboratory abnormalities (i.e., test results outside of the reference range) for hematology and biochemistry parameters; Grade 0 is normal and Grades 1 to 4 represent worsening levels of the parameter outside of the normal range in the specified direction of the abnormality (high and low are above and below the range, respectively). Not every laboratory abnormality qualified as an adverse event (AE). A laboratory test result was reported as an AE if it met any of the following criteria: was accompanied by clinical symptoms; resulted in a change in study treatment; resulted in a medical intervention or a change in concomitant therapy; or was clinically significant in the investigator's judgment. Baseline was defined as the last available assessment prior to first receipt of study drug. Abs = absolute count; SGOT/AST = aspartate aminotransferase; SGPT/ALT = alanine aminotransferase |

Title | Model-Based Annualized Bleed Rates (ABR) for Treated Bleeds, All Bleeds, Treated Joint Bleeds, Treated Target Joint Bleeds, and Treated Spontaneous Bleeds |
---|---|
Description | The number of bleeds over the efficacy period was analyzed as an ABR using a negative binomial regression model. Treated bleeds: bleeds followed by a hemophilia medication reported to be a "Treatment for bleed". All bleeds: included both treated and non-treated bleeds. Treated joint bleeds: treated bleeds where bleed type was "joint bleed" accompanied by at least one of following symptoms: "increased swelling or warmth of the skin over the joint", "increasing pain" or "decreased range of motion or difficulty using the joint compared with baseline". Treated target joint bleeds: treated joint bleeds that occurred in a target joint, defined as a joint in which ≥3 treated joint bleeds occurred during the 24 weeks prior to study entry. Treated spontaneous bleeds: treated bleeds with no other known contributing factor such as trauma or procedure/surgery. For all bleed types, bleeds due to surgery/procedure were excluded. Bleeds occurring after dose up-titration have been excluded. |
Time Frame | From first dose of emicizumab until dose up-titration or withdrawal from treatment (median [min-max] efficacy period: 103.14 [1.1-108.3] weeks) |

Description | Treated spontaneous bleeds: treated bleeds with no other known contributing factor such as trauma or procedure/surgery. Bleeds due to surgery/procedure were excluded. The 72-hour rule was implemented: two bleeds of the same type and at the same anatomical location are counted as one bleed if the second bleed occurs within 72 hours from the last treatment for the first bleed. Included data before up-titration only, for participants whose dose was up-titrated. |
Time Frame | From first dose of emicizumab until dose up-titration or withdrawal from treatment (median [min-max] efficacy period: 103.14 [1.1-108.3] weeks) |

---|---|
Description | The Haem-A-QoL questionnaire was designed for adult participants (greater than or equal to 18 years old) with hemophilia. It consists of 46 items comprising 10 domains: physical health, treatment, work and school, dealing with hemophilia, feelings, familly planning, future, partnerships and sexuality, sports and leisure, and view of yourself. Items are rated by participants with one of five response options: never, seldom, sometimes, often, and always; although, for some items there is also a 'not applicable' option. The Total Score is based on the scores for each domain and ranges from 0 to 100, with lower scores reflective of better quality of life. |

---|---|
Description | The EQ-5D-5L is a generic, self-reported, preference-based health utility measure that consists of six questions and is used to assess health status and inform pharmacoeconomic evaluations. The index utility score is based on the participant's assessment of their health on five scales: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. It ranges from -0.224 to 1, with 0 corresponding to death and 1 corresponding to full health; negative values correspond to health states worse than death. Higher scores indicate better quality of life. |
