Evaluation of Direct Oral Anticoagulant Reversal Agents in Intracranial Hemorrhage

ImportanceDirect oral anticoagulant (DOAC)–associated intracranial hemorrhage (ICH) has high morbidity and mortality. The safety and outcome data of DOAC reversal agents in ICH are limited.ObjectiveTo evaluate the safety and outcomes of DOAC reversal agents among patients with ICH.Data SourcesPubMed, MEDLINE, The Cochrane Library, Embase, EBSCO, Web of Science, and CINAHL databases were searched from inception through April 29, 2022.Study SelectionThe eligibility criteria were (1) adult patients (age ≥18 years) with ICH receiving treatment with a DOAC, (2) reversal of DOAC, and (3) reported safety and anticoagulation reversal outcomes. All nonhuman studies and case reports, studies evaluating patients with ischemic stroke requiring anticoagulation reversal or different dosing regimens of DOAC reversal agents, and mixed study groups with DOAC and warfarin were excluded.Data Extraction and SynthesisPreferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were used for abstracting data and assessing data quality and validity. Two reviewers independently selected the studies and abstracted data. Data were pooled using the random-effects model.Main Outcomes and MeasuresThe primary outcome was proportion with anticoagulation reversed. The primary safety end points were all-cause mortality and thromboembolic events after the reversal agent.ResultsA total of 36 studies met criteria for inclusion, with a total of 1832 patients (967 receiving 4-factor prothrombin complex concentrate [4F-PCC]; 525, andexanet alfa [AA]; 340, idarucizumab). The mean age was 76 (range, 68-83) years, and 57% were men. For 4F-PCC, anticoagulation reversal was 77% (95% CI, 72%-82%; I2 = 55%); all-cause mortality, 26% (95% CI, 20%-32%; I2 = 68%), and thromboembolic events, 8% (95% CI, 5%-12%; I2 = 41%). For AA, anticoagulation reversal was 75% (95% CI, 67%-81%; I2 = 48%); all-cause mortality, 24% (95% CI, 16%-34%; I2 = 73%), and thromboembolic events, 14% (95% CI, 10%-19%; I2 = 16%). Idarucizumab for reversal of dabigatran had an anticoagulation reversal rate of 82% (95% CI, 55%-95%; I2 = 41%), all-cause mortality, 11% (95% CI, 8%-15%, I2 = 0%), and thromboembolic events, 5% (95% CI, 3%-8%; I2 = 0%). A direct retrospective comparison of 4F-PCC and AA showed no differences in anticoagulation reversal, proportional mortality, or thromboembolic events.Conclusions and RelevanceIn the absence of randomized clinical comparison trials, the overall anticoagulation reversal, mortality, and thromboembolic event rates in this systematic review and meta-analysis appeared similar among available DOAC reversal agents for managing ICH. Cost, institutional formulary status, and availability may restrict reversal agent choice, particularly in small community hospitals.

Previous meta‐analyses assessed andexanet alfa (AA) or prothrombin complex concentrate (PCC) products for the treatment of Factor Xa inhibitor (FXaI)‐associated major bleeding. However, they did not include recent studies or assess the impact of the risk of bias. We conducted a systematic review with meta‐analysis on the effectiveness of AA versus PCC products for FXaI‐associated major bleeding, inclusive of the studies' risk of bias. PubMed and Embase were searched for comparative studies assessing major bleeding in patients using FXaI who received AA or PCC. We used the Methodological Index for NOn‐Randomized Studies (MINORS) checklist and one question from the Joanna Briggs Institute (JBI) Critical Appraisal of Case Series tool to assess the risk of bias. Random‐effects meta‐analyses were performed to provide a pooled estimate for the effect of AA versus PCC products on hemostatic efficacy, in‐hospital mortality, 30‐day mortality, and thrombotic events. Low–moderate risk of bias studies were meta‐analyzed separately, as well as combined with high risk of bias studies. Eighteen comparative evaluations of AA versus PCC were identified. Twenty‐eight percent of the studies (n = 5) had low–moderate risk and 72% (n = 13) had a high risk of bias. Studies with low–moderate risk of bias suggested improvements in hemostatic efficacy [Odds Ratio (OR) 2.72 (95% Confidence Interval (CI): 1.15–6.44); one study], lower in‐hospital mortality [OR 0.48 (95% CI: 0.38–0.61); three studies], and reduced 30‐day mortality [OR 0.49 (95% CI: 0.30–0.80); two studies] when AA was used versus PCC products. When studies were included regardless of the risk of bias, pooled effects showed improvements in hemostatic efficacy [OR 1.36 (95% CI: 1.01–1.84); 12 studies] and reductions in 30‐day mortality [OR 0.53 (95% CI: 0.37–0.76); six studies] for AA versus PCC. The difference in thrombotic events with AA versus PCC was not statistically significant in the low–moderate, high, or combined risk of bias groups. The evidence from low–moderate quality real‐world studies suggests that AA is superior to PCC in enhancing hemostatic efficacy and reducing in‐hospital and 30‐day mortality. When studies are assessed regardless of the risk of bias, the pooled hemostatic efficacy and 30‐day mortality risk remain significantly better with AA versus PCC.
