Arm Label
FIB Grifols
Arm Description
FIB Grifols is the IP and will be administered via slow intravenous (IV) infusion at a rate not to exceed 5 mL/minute. Dosing will be individually calculated for each subject based on the target plasma fibrinogen level according to the type of bleeding, measured actual plasma fibrinogen level before infusion, and body weight. The IP will be administered according to the nominal potency of the product.
Outcomes
Primary Outcome Measures
Hemostatic efficacy of FIB Grifols in on-demand treatment of all documented acute bleeding episodes as assessed by the Independent Endpoint Adjudication Committee (IEAC) Using a 4-Point Scale
To clinically evaluate the hemostatic efficacy of FIB Grifols in on-demand treatment of all documented acute bleeding episodes in subjects with congenital fibrinogen deficiency as determined by the the proportion of successful treatment responses (Yes/No) indicated by a hemostatic efficacy rating of "Excellent" or "Good" as assessed by the IEAC using a 4 point scale. Hemostatic efficacy will be determined at end of treatment observation period (either at Day 3 for non-life threatening bleeding episodes, at Day 7 for life-threatening bleeding episodes, or at 24 hours after the end of the last infusion of FIB Grifols, whichever is later).
Hemostatic efficacy of FIB Grifols in perioperative management of bleeding during and after all documented surgical procedures as assessed by the IEAC Using a 4-Point Scale
To clinically evaluate the hemostatic efficacy of FIB Grifols in the perioperative management of bleeding during and after all documented surgical procedures in subjects with congenital fibrinogen deficiency as determined by the the proportion of successful treatment responses (Yes/No) indicate by an adjudicated hemostatic efficacy rating of "Success" in preventing excessive bleeding during and after all documented surgical procedures as assessed by the IEAC using a 4 point scale. Hemostatic efficacy will be determined at end of treatment observation period (either at Day 3 for minor surgical procedures, at Day 7 for major surgical procedures, or at 24 hours after the end of the last infusion of FIB Grifols, whichever is later).
