Cryo-FIRST: Effectiveness of INTERCEPT Fibrinogen Complex (IFC) for Trauma-Associated Hemorrhage

Overview

The objective of this multicenter, single-arm, observational study is to determine the feasibility and effectiveness of early administration of FDA-approved, pre-thawed Pathogen Reduced Cryoprecipitated Fibrinogen Complex (INTERCEPT Fibrinogen Complex, IFC) in trauma patients with hemorrhagic shock (HS) and functional hypofibrinogenemia. This study will determine whether rapid point-of-care testing for functional hypofibrinogenemia and availability of a shelf-stable fibrinogen complex (IFC) results in shorter time to administration of fibrinogen replacement and correction of functional hypofibrinogenemia, as compared with historical controls and published literature using conventional cryoprecipitate-AHF (CRYO-AHF). This study aims to: * Demonstrate the feasibility and response to early administration of pre-thawed IFC when ordered during initial resuscitation of severely injured patients with HS and functional hypofibrinogenemia. * Assess the effectiveness of early administration of pre-thawed IFC on correction of functional hypofibrinogenemia and on proximate process measures of resuscitation, including time to hemostasis, time to completion of resuscitation, and total volume of resuscitation. * Assess clinical outcomes in severely injured patients with HS and functional hypofibrinogenemia receiving early administration of pre-thawed IFC.

This is a multicenter, pragmatic, observational, single-arm study evaluating the feasibility and effectiveness of early administration of pre-thawed Pathogen Reduced Cryoprecipitated Fibrinogen Complex (INTERCEPT Fibrinogen Complex, IFC) in trauma patients with hemorrhagic shock and functional hypofibrinogenemia. Adult trauma patients age ≥18 years, or estimated weight ≥50 kg if age is unknown, who present to a participating trauma center within 1 hour of estimated time of injury and meet criteria for hemorrhagic shock will be screened using the point-of-care Quantra® Hemostasis Analyzer. Functional hypofibrinogenemia is defined as FCS \<1.6 hPa by Quantra® point-of-care testing. Patients are eligible only if cryoprecipitate administration is clinically indicated by the treating physician, IFC is available at the time of enrollment, and the patient will receive IFC per standard of care. Following administration of IFC, an additional Quantra® point-of-care test will be completed at completion of resuscitation (COR), defined as discontinuation of the massive transfusion protocol (MTP), to evaluate fibrinogen response. Additional IFC may be administered if additional hemostatic correction is determined to be needed by the treating clinician, repeat point-of-care testing, or clinical judgment. Primary outcomes are the proportion of patients with hemorrhagic shock and functional hypofibrinogenemia who receive IFC within 60 minutes of presentation to the participating trauma center and the proportion of patients with successful correction of functional hypofibrinogenemia at COR. Secondary outcomes include time to hemostasis, estimated blood loss, transfusion burden/total volume of resuscitation, mortality at 3 hours, 6 hours, 24 hours, and 30 days or in-hospital mortality, and adverse clinical outcomes through 30 days, hospital discharge, or death, whichever occurs first. Outcomes may be compared descriptively with historical controls, site medical databases, and published literature using CRYO-AHF. Four Level 1 trauma centers will enroll approximately 320 patients over approximately 24 months.
