  Purpose

To assess whether a rivaroxaban-based anticoagulation strategy, following successful TAVR, compared to an antiplatelet-based strategy, is superior in reducing death or first thromboembolic events (DTE).

To assess the primary bleeding events (PBE) of the rivaroxaban-based strategy compared to an antiplateletbased strategy, following TAVR.

Official Title: Global Multicenter, Open-label, Randomized, Event-driven, Active-controlled Study Comparing a rivAroxaban-based Antithrombotic Strategy to an antipLatelet-based Strategy After Transcatheter aortIc vaLve rEplacement (TAVR) to Optimize Clinical Outcomes

Primary Outcome Measures:
  • Death or first adjudicated thromboembolic event (DTE) defined as composite of all-cause death and adjudicated any stroke, MI, symptomatic valve thrombosis, PE, DVT, or non-CNS SE [ Time Frame: Up to 25 months ]
    MI: Myocardial infarction, PE: Pulmonary embolism, DVT: Deep vein thrombosis, non-CNS SE: Non-central nervous system systemic embolism

  • Primary bleeding event defined as the composite of adjudicated life-threatening, disabling or major bleeding, classified according to the VARC definitions following the BARC classification [ Time Frame: Up to 25 months ]
    VARC:Valve academic research consortium, BARC: Bleeding academic research consortium


Secondary Outcome Measures:
  • Composite of cardiovascular death, any stroke, myocardial infarction, symptomatic valve thrombosis, pulmonary embolism, deep vein thrombosis or non-CNS systemic embolism [ Time Frame: Up to 25 months ]
  • Net-clinical-benefit defined as the composite of all-cause death, any stroke, myocardial infarction, symptomatic valve thrombosis, pulmonary embolism, deep vein thrombosis, non-CNS systemic embolism, life threatening, disabling and major bleeds [ Time Frame: Up to 25 months ]
  • Bleeding complications defined as any of the following: composite of TIMI major or minor bleeds, ISTH major bleeding, composite of BARC 2, 3, or 5 bleeding [ Time Frame: Up to 25 months ]
    TIMI: Thrombolysis in Myocardial Infarction, ISTH: International Society on Thrombosis and Haemostasis

Criteria

Inclusion Criteria:

  • Successful TAVR (Transcatheter Aortic Valve Replacement) of an aortic valve stenosis (either native or valve-in-valve)

    • By iliofemoral or subclavian access
    • With any approved/marketed device

Exclusion Criteria:

  • Atrial fibrillation (AF), current or previous, with an ongoing indication for oral anticoagulant treatment
  • Any other indication for continued treatment with any oral anticoagulant (OAC)
  • Known bleeding diathesis (such as but not limited to active internal bleeding, clinically significant bleeding, platelet count ≤ 50,000/mm3 at screening, hemoglobin level < 8.5 g/dL, active peptic ulcer or known gastrointestinal (GI) bleeding, history of intracranial hemorrhage or subdural hematoma)
