FIB Grifols Congenital Deficiency for On-demand Treatment and Surgical Prophylaxis
A Prospective, Multicenter, Open-label, Single-arm Study to Evaluate the Efficacy and Safety of Human Plasma-derived Fibrinogen Concentrate (FIB Grifols) in Subjects With Congenital Afibrinogenaemia and Severe Hypofibrinogenemia Requiring Either On-demand Treatment for Acute Bleeding or Surgical Prophylaxis
This is a phase 3, multi-center, prospective, open-label, single-arm, clinical trial to be carried out in subjects with congenital fibrinogen deficiency manifested as afibrinogenemia or severe hypofibrinogenemia.
This clinical trial is planned to be performed at study sites in multiple countries. It is planned to include a maximum of 32 adult and pediatric subjects with congenital fibrinogen deficiency in order to provide at least 28 evaluable acute bleeding episodes and/or surgical procedures.

- Is a female who is pregnant, breastfeeding or, if of child-bearing potential, unwilling to practice a highly effective method of contraception (eg, oral, injectable, or implantable hormonal methods of contraception, placement of an IUD or intrauterine system, condom or occlusive cap with spermicidal foam/gel/film/cream/suppository, male sterilization, or true abstinancea) throughout the study.
- Has any medical condition which is likely to interfere with the evaluation of the IP and/or the satisfactory conduct of the clinical trial according to the investigator's judgment.
- Has congenital or acquired bleeding disorders other than congenital fibrinogen deficiency.
- Has life expectancy of less than 6 months.

Intervention / Treatment |
---|---|
Experimental: FIB Grifols
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. |

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
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
Time Frame: Up to Day 7
|
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).
|
Up to Day 7
|
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
Time Frame: Up to Day 7
|
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).
