Reversal of factor Xa inhibitors associated intracranial haemorrhage at a tertiary medical centre

Four-factor prothrombin complex concentrate (4F-PCC) has been widely used off-label for FXaI-associated bleeding. The purpose of this study...

| Summary: | Prior to the approval of andexanet, there were no FDA-approved reversal agents indicated for the treatment of factor Xa inhibitor (FXaI) associated major bleed. Four-factor prothrombin complex concentrate (4F-PCC) has been widely used off-label for FXaI-associated bleeding. The purpose of this study was to compare the effectiveness and safety of andexanet and 4F-PCC for the reversal of FXaI-associated intracranial haemorrhage. The primary end point is in-hospital mortality; secondary endpoints include haemostatic efficacy and safety. This study is a singlecentre, retrospective chart review, including patients admitted between 1 January 2016 and 15 August 2019, who received 4F-PCC or andexanet for the management of FXaI-associated intracranial haemorrhage. Of the 45 patients included in this study, 23 patients were in the andexanet group and 22 were in the 4F-PCC group. At index admission, mean age was 76 years and the majority of patients (64%) were on apixaban with 33% presented with Glasgow Coma Scale 24 (GCS) score less than 12. At hospital discharge, 47% of patients in the andexanet group had died or discharged to hospice compared with 45% in the 4F-PCC group. No thromboembolic events were observed in either group within 5 days after administration of the reversal agent. The results of this study suggest that haemostasis and mortality at discharge during the index hospitalization appears to be similar between groups. Prospective randomized control trials comparing safety and efficacy of andexanet and 4F-PCC are needed. |
