A Randomized Controlled Trial With Resolute Onyx in One Month Dual Antiplatelet Therapy (DAPT) for High-Bleeding Risk Patients

The purpose of this study is to evaluate the clinical safety and effectiveness of the Resolute Onyx stent in subjects deemed at high risk for bleeding and/or medically unsuitable for more than 1 month DAPT treatment receiving reduced duration (1 month) of DAPT following stent implantation.

Primary outcomes

  1. Composite endpoint: Cardiac Death, Myocardial Infarction, or Stent Thrombosis

    Time frame: 1 year post-procedure

    Powered for non-inferiority against BioFreedom (control), is a composite of cardiac death, myocardial infarction and definite/probable stent thrombosis. The combined clinical outcome of cardiac death, MI or stent thrombosis

Secondary outcomes

  1. Target Lesion Failure

    Time frame: 2 year post-procedure

    Defined as cardiac death, target vessel myocardial infarction (Q wave and non Q wave), or clinically driven target lesion revascularization(TLR) by percutaneous or surgical methods

  2. Procedure Success

    Time frame: 2 year post-procedure

    Attainment of <30% residual stenosis by QCA (or <20% by visual assessment) AND TIMI flow 3 after the procedure, using any percutaneous method without the occurrence of MACE during the hospital stay.

  3. Cardiac Death

    Time frame: 2 year post- procedure

    All deaths including cardiac death

  4. Major Cardiac Event

    Time frame: 2 year post- procedure

    Major adverse cardiac event (MACE) defined as composite of death, myocardial infarction, or repeat target lesion revascularization (clinically driven) by percutaneous or surgical methods

  5. Myocardial Infarction

    Time frame: 2 year post-procedure

    All myocardial infarction including Target Vessel Myocardial Infarction (TVMI)

  6. Target Vessel Failure

    Time frame: 2 year post-procedure

    Target vessel failure (TVF) defined as composite of cardiac death, target vessel myocardial infarction, or clinically-driven target vessel revascularization (TVR) by percutaneous or surgical methods.

  7. Revascularization

    Time frame: 2 year post-procedure

    All revascularizations (TLR, TVR and non-TVR)

  8. Stent Thrombosis

    Time frame: 2 year post-procedure

    Stent thrombosis (per Academic Research Consortium (ARC) definition)

  9. Bleeding

    Time frame: 2 year post-procedure

    Bleeding per BARC criteria

  10. Stroke

    Time frame: 2 year post-procedure

    Stroke

  11. Lesion Success

    Time frame: 2 year post-procedure

    The attainment of <30% residual stenosis by QCA (or < 20% by visual assessment) AND TIMI flow 3 after the procedure, using any percutaneous method

  12. Device success

    Time frame: 2 year post-procedure

    Attainment of <30% residual stenosis by QCA (or <20% by visual assessment) AND TIMI flow 3 after the procedure, using the assigned device only.
