Outcome Measures

Primary Outcomes (1)

  • The incidence of thromboembolic adverse drug reactions (ADRs)

    The incidence of thromboembolic ADRs in patients receiving Fibryga for on-demand treatment of bleeding, including major bleeding, will be documented

    Day 0-28

Secondary Outcomes (4)

  • 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

  • Duration of BEs

    Within 2-24 hours following treatment of BEs

  • Incidence of treatment-emergent adverse events (safety)

    Day 0-28

Study Arms (1)

Fibryga

Fibryga (human plasma-derived fibrinogen concentrate)

Biological: Fibryga

Interventions

Sampling MethodNon-Probability Sample
Study Population

Approximately 25 patients with a documented diagnosis of congenital afibrinogenemia or hypofibrinogenemia are planned to be documented in this study

You may qualify if:

  • 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

You may not qualify if:

  • 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
  • Participation in an interventional clinical study at the time of or within 4 weeks prior to enrolment
