Conference report: Updated results from ongoing phase III RE-VERSE AD study on safety and efficacy of idarucizumab (Praxbind) in urgent situations

Biospace Inc.

In trial of 494 patients who had uncontrolled or life-threatening bleeding or required emergency surgery or an invasive procedure, primary endpoint of reversal of anticoagulant effect of dabigatran with 5g of idarucizumab within 4 hours was 100% Reversal was evident immediately.


Recurrent Hospitalization Among Patients With Atrial Fibrillation Undergoing Intracoronary Stenting Treated With 2 Treatment Strategies of Rivaroxaban or a Dose-Adjusted Oral Vitamin K Antagonist Treatment Strategy


Study (n=2124) found either rivaroxaban 15 mg OD+P2Y12 inhibitor monotherapy or 2.5 mg rivaroxaban BD plus dual antiplatelet therapy (DAPT) was associated with a reduced risk of all-cause mortality/recurrent hospitalisation vs standard-of-care vitamin k antagonist+DAPT.


Warfarin utilisation and anticoagulation control in patients with atrial fibrillation and chronic kidney disease


Study (n=123188) found warfarin use decreased with increasing severity of chronic kidney disease (CKD) (57.2%–46.4%), but was higher in patients on dialysis (62.3%). Proportion of patients with time in range (TIR) ≥60% decreased with CKD severity; 21% on dialysis achieved TIR≥60%.


Prevention of Bleeding in Patients with Atrial Fibrillation Undergoing PCI

New England Journal of Medicine

The administration of either low-dose rivaroxaban (R)+P2Y12 inhibitor for 12 months or very-low-dose R+DAPT for 1, 6, or 12 months was associated with a
lower rate of clinically significant bleeding than was standard therapy with a vit K antagonist+DAPT for 1, 6, or 12 months.


Under-prescribing of Prevention Drugs and Primary Prevention of Stroke and Transient Ischaemic Attack in UK General Practice: A Retrospective Analysis

PLOS Medicine

UK study (n=29043) found >50% of people eligible for lipid-lowering, anticoagulant, or antihypertensive drugs were not prescribed them prior to first stroke/TIA. The authors estimate that around 12000 first strokes could be prevented/year annually through optimal prescribing.


Extended-Duration Betrixaban Reduces the Risk of Stroke Versus Standard-Dose Enoxaparin Among Hospitalized Medically Ill Patients: An APEX Trial Substudy (Acute Medically Ill Venous Thromboembolism Prevention With Extended Duration Betrixaban)


This study (n=7513) reports that there were fewer all-cause strokes (0.54% v 0.97%; RR=0.56; P=0.032) and ischaemic strokes (0.48% v 0.91%; RR=0.53; P=0.026) among patients treated with betrixaban v enoxaparin through 77 days of follow-up.


Trade-off of myocardial infarction vs. bleeding types on mortality after acute coronary syndrome: lessons from the Thrombin Receptor Antagonist for Clinical Event Reduction in Acute Coronary Syndrome (TRACER) randomized trial

European Heart Journal

Analysis of the TRACER trial (n=12,944) found that MI was associated with a greater risk of mortality compared with Bleeding Academic Research Consortium (BARC) 2 and 3a bleeding; a similar risk of mortality to BARC 3c bleeding; and a lower risk of mortality than BARC 3c bleeding.


Ticagrelor versus Clopidogrel in Symptomatic Peripheral Artery Disease

New England Journal of Medicine

RCT (n=13,885) found that ticagrelor is not superior to clopidogrel for reducing cardiovascular events (10.8% vs 10.6%, HR 1.02, 95% CI 0.92-1.13). Major
bleeding occurred at similar rates (1.6% in both groups, HR 1.10, 95% CI 0.84-1.43).
