Design outcomes

Primary

MeasureTime frame
Main Objective: Safety Objectives: •To demonstrate safety of GreenGene™ F with respect to inhibitor development (neutralizing anti-Factor VIII antibodies) over a minimum of additional 50 exposure days (primary objective) •To assess the long-term (additional 50 exposure days) safety of GreenGene™ F. Efficacy Objectives: •To evaluate the hemostatic efficacy of GreenGene™ F in prophylaxis (rate of breakthrough bleeding) and on demand treatment in the management of acute bleeding events •To evaluate the physicians and subjects rating of response for on demand treatment of bleeding episodes ;Secondary Objective: Not applicable;Primary end point(s): Efficacy endpoints for this study include: •The consumption of Factor VIII, expressed as number of infusions and IU/kg per month and per year, as well as •IU/kg per event (prophylaxis, on-demand, and surgery). •Frequency of breakthrough bleedings; •Physicians and subject evaluation of efficacy (on-demand and surgery); •Number of infusions of study drug per bleeding episode •Unit of FVIII per treatment (prophylaxis) Safety endpoints: All safety analyses will be summarized and presented for the Safety Analysis Set. The safety of GreenGene™ F will be assessed by monitoring the rate of inhibitor incidence, adverse effects and changes in clinical laboratory parameters;Timepoint(s) of evaluation of this end point: Safety and efficacy; Following a minimum 50 exposure days for both prophylaxis and on demand patients
