title: Safety and Effectiveness of Factor VIII Inhibitor Bypassing Activity (FEIBA) and Fresh Frozen Plasma in Oral Anticoagulant-Associated Intracranial Hemorrhage: A Retrospective Analysis.
abstract: BACKGROUND
  Oral anticoagulant (OAT)-associated intracranial hemorrhage (ICH) is a life-threatening emergency for which prothrombin complex concentrates (PCC) are considered first-line reversal agents. The only approved PCC in the USA for warfarin-associated ICH is non-activated PCC. Little data are available regarding the safety and effectiveness of factor VIII inhibitor bypassing activity (FEIBA) which is an activated prothrombin complex concentrate (aPCC). The aim of this analysis was to assess the safety and effectiveness of FEIBA compared to fresh frozen plasma (FFP) for reversal of OAT-associated ICH.
  
  
  METHODS
  Data were retrospectively collected to compare coagulation markers and in-hospital clinical outcomes in patients who received aPCC with or without FFP versus FFP alone for the reversal of OAT-associated ICH.
  
  
  RESULTS
  Eighty-four patients met inclusion criteria; 50 patients received FFP alone, and 34 patients received FEIBA (mean dose 20 U/kg) with or without FFP for OAT-associated ICH. The proportion of diagnosed thrombotic events during hospitalization was similar in both groups (8% in the FFP group vs. 12% in the FEIBA group; P = 0.56). Median time to INR < 1.5 was achieved faster in the FEIBA group versus the FFP group (0.5 h [IQR 0.5-1.] vs. 10 h [IQR 5-16.3], respectively; P < 0.001) reflecting a trend toward shorter median time to neurosurgical intervention. Hematoma expansion, length of stay, and all-cause mortality were similar between both groups.
  
  
  CONCLUSIONS
  Administration of FEIBA does not appear to increase the risk of thrombotic events compared with FFP. FEIBA administration resulted in faster INR reversal with a trend toward shorter time to neurosurgical intervention. However, there was no difference in hematoma expansion, mortality or length of stay.
