|---|---|---|---|
| Primary | Incidence Rate of FVIII Inhibitor Development | up to 52 weeks ± 2 weeks | An inhibitor test result ≥0.6 Bethesda units (BU)/mL, identified and confirmed by re-testing of a second sample obtained within 2 to 4 weeks, was considered positive. Both tests were to be performed using the Nijmegen-modified Bethesda Assay by the central laboratory. The incidence rates along with the 95% confidence interval (CI) were summarized for all titers for subjects with 50 or more exposure days (EDs) to rFVIIIFc and a valid inhibitor test after the 50th exposure. In addition, the incidence rates for all subjects regardless of their exposure days to rFVIIIFc were also summarized. The 95% CI was calculated using Clopper-Pearson exact method. |
| Primary | Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs) | up to 52 weeks + 30 days ± 1 week | AE=any untoward medical occurrence that did not necessarily have a causal relationship with treatment, and could be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of study product, whether related or not. TEAE=AE present prior to receiving the first injection of Advate or rFVIIIFc that subsequently worsened in severity or not present prior to receiving the first injection but subsequently appeared before the last visit on study. Serious AE (SAE)=AE resulting in death, immediate risk of death, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability/incapacity, or a congenital anomaly/birth defect, or any other medically important event. AEs emergent between the first Advate injection and first on-study rFVIIIFc injection (Sequential PK Subgroup) or during the surgical/rehabilitation period (Surgery Subgroup) are presented separately. |
| Primary | Number of Participants With Potentially Clinically Significant Abnormal Laboratory Values From Baseline | up to 52 weeks ± 2 weeks | Clinical laboratory evaluations included hematology and blood chemistry. Table does not include laboratory tests evaluated during the surgical/rehabilitation period. ULN=upper limit of normal. |

| Secondary | Number of Days From Last Treatment Injection to a New Bleeding Episode | up to 52 weeks ± 2 weeks (efficacy period as defined in description) | Number of days from the last injection to treat a bleeding episode to a new bleeding episode, analyzed for per evaluable bleeding episode and per participant. For "per participant" values, number of days from last injection to treat a bleed to a new bleeding episode is averaged across all evaluable bleeding episodes for each participant first, and then descriptive statistics were calculated across participants. A follow-up injection administered \>72 hours after the most recent injection given to treat a bleed was considered a new bleed at the same location and was classified as type=Unknown (not evaluable). The efficacy period in Arms 1 and 2 began with the first prophylactic dose of rFVIIIFc and ended with the last dose (regardless of reason for dosing). The efficacy period in Arm 3 began at the time of last PK rFVIIIFc sampling timepoint and ended at the date of the last study visit.

All injections given from the initial sign of a bleed until the last date/time within the bleed window are counted. The resolution of a bleed is defined as no sign of bleeding following injection for the bleed. The efficacy period in Arms 1 and 2 began with the first prophylactic dose of rFVIIIFc and ended with the last dose (regardless of reason for dosing). The efficacy period in Arm 3 began at the time of last PK rFVIIIFc sampling timepoint and ended at the date of the last study visit. Periods of PK evaluations and surgery/rehabilitation are not included in the efficacy period. |
| Secondary | Number of Injections Required for Resolution of a Bleeding Episode by Location of Bleed | up to 52 weeks ± 2 weeks (efficacy period as defined in description) | Please see Outcome Measure 20 for a definition of the efficacy period. A bleeding episode started from the first sign of a bleed, and ended 72 hours after the last treatment for the bleeding, within which any symptoms of bleeding at the same location, or injections less than or equal to 72 hours apart, were considered the same bleeding episode. All injections given from the initial sign of a bleed until the last date/time within the bleed window were counted. The resolution of a bleed was defined as no sign of bleeding following injection for the bleed. Bleeding episodes that presented in multiple locations are included as a single event in the overall summary for the number of injections to resolve that bleeding episode but are included in summaries for each location. |
