Study Endpoints

Primary Endpoints

Number of Participants With Inhibitory Antibodies to Factor VIII (FVIII)
Baseline through end of study (53 months)

Inhibitory antibodies to Factor VIII were measured by the Nijmegen modification of the Bethesda assay. Inhibitors had to be confirmed by 2 separate assessments within a 2 to 4 week period from the central laboratory.

Annualized Bleed Rate (ABR) - Spontaneous Bleeds
Baseline through end of study (53 months)

The ABR was assessed based upon each individual bleeding episode. A bleeding episode was defined as subjective (pain consistent with a joint bleed) or objective evidence of bleeding which may or may not require treatment with FVIII. The ABR of spontaneous bleeds was reported separately for twice weekly, PK-t R, each of the every 5 days and every 7 days treatment regimens at the time of bleed.
