Outcomes

Primary Outcomes

The Incidence Rate of FVIII Inhibitors (Greater Than or Equal to 0.6 Bethesda Units (BU))

The incidence rate of FVIII inhibitors was calculated by including all patients with inhibitors in the nominator and including all patients with a minimum 50 exposure plus any patients with less than 50 exposures but with inhibitors in denominator.

Time frame: The adverse events were collected throughout the trial, corresponding to an average of 138 days per subject.

Secondary Outcomes

Frequency of Adverse Events (AEs)

Adverse event was defined as events occurring after administration of trial product. Severe AEs: considerable interference with subject's daily activities, unacceptable. Moderate AEs: Marked symptoms, moderate interference with the patient's daily activities. Mild AEs: No or transient symptoms, no interference with the patient's daily activities. Serious AE: AE that at any dose results in any of the following: death, a life-threatening experience, in-subject hospitalization/prolongation of existing hospitalisation, persistent/significant disability/incapacity/congenital anomaly/birth defect.

Time frame: The adverse events were collected throughout the trial, corresponding to an average of 138 days per subject
