Study Overview
Brief Summary
Open-label, Uncontrolled, Multicenter Observational Study on the Safety and Efficacy of Fibryga in Congenital Fibrinogen Deficiency
Detailed Description
There is a need to increase the body of data on treatment effectiveness and safety in the ultra-rare setting of congenital fibrinogen deficiency. Real-world evidence (RWE) derived from non-interventional studies can describe product utilization, demonstrate value, and facilitate benefit-risk assessments; RWE can only be fully assessed once a product is launched and used in a real-life setting.
This post-marketing, observational study is designed to collect information concerning safety, efficacy, and outcomes of Fibryga administration in routine clinical use in patients of any age with congenital afibrinogenemia or hypofibrinogenemia. Documentation of the administration of Fibryga in clinical practice for the treatment of both minor and major bleeding events (BEs) will not only enhance the knowledge on the efficacy and safety profile of Fibryga, but will also gather information that cannot be obtained in the same way in controlled clinical studies. These observational data will support the safety and efficacy data generated with Fibryga in good clinical practice (GCP) clinical studies, providing benefit for both physicians and patients.

Inclusion Criteria
- •Patients of any age with a documented diagnosis of congenital afibrinogenemia or hypofibrinogenemia expected to require on-demand in-hospital treatment for BEs with Fibryga
Exclusion Criteria
- •Bleeding disorder other than congenital fibrinogen deficiency
- •Patients with acquired fibrinogen deficiency or dysfibrinogenemia
- •Suspicion of an anti-fibrinogen inhibitor as indicated by previous in vivo recovery, if available, of <0.5 (mg/dL)/(mg/kg); there is currently no standard test for inhibitors

Arms & Interventions
Fibryga
Fibryga (human plasma-derived fibrinogen concentrate)
Intervention: Fibryga (Biological)
Outcomes
Primary Outcomes
The incidence of thromboembolic adverse drug reactions (ADRs)
Time Frame: Day 0-28
The incidence of thromboembolic ADRs in patients receiving Fibryga for on-demand treatment of bleeding, including major bleeding, will be documented
Secondary Outcomes
- Duration of BEs(Within 2-24 hours following treatment of BEs)
- Incidence of treatment-emergent adverse events (safety)(Day 0-28)
- Hemostatic efficacy of Fibryga for all bleeding events (BEs) collected in the study will be assessed by the investigator using a 4-point hemostatic efficacy scale(Within 2-24 hours following treatment of BEs)
- Dosage of Fibryga(Within 2-24 hours following treatment of BEs)
