Study Endpoints

Primary Endpoints

Percentage of Serious Bleeding Episodes Responsive to OBI-1
24 hours after initiation of treatment

The initial serious ("qualifying") bleeding episode for each subject was analyzed for the primary efficacy outcome measure. A 'positive response' is defined as 'effective' (bleeding stopped with clinical control and FVIII levels of 50% or higher ) or 'partially effective' (bleeding reduced with clinical stabilization and FVIII levels of 20% or higher) control of bleeding, as determined by the investigator using a 4-point rating scale (effective - partially effective - poorly effective - not effective). 'Poorly effective' is defined as 'bleeding slightly reduced or unchanged and FVIII levels of less than 50%'. 'Not effective' is defined as 'bleeding worsening and FVIII levels of less than 50%'.
