Participants With Bleeding Academic Research Consortium Type 3 or Greater (BARC ≥3) Events Up to 48 h or at Hospital Discharge, As Adjudicated by the Independent Clinical Events Committee (CEC) [ Time Frame: Study drug administration (Day 1) up to 48 h post study drug initiation or at hospital discharge, whichever occurs first ]

BARC ≥3 includes:

Type 3a-3c: clinical, laboratory, and/or imaging evidence of bleeding, which includes any transfusion with overt bleeding, bleeds that result in surgical intervention or administration of IV vasoactive drugs, overt bleeds with a hemoglobin drop greater than or equal to 3 grams (g)/deciliters (dL) to greater than or equal to 5 g/dL, cardiac tamponade caused by bleeding, intracranial hemorrhage, and intraocular bleeds that compromise vision.

Type 4: (Coronary Artery Bypass Grafting-related Bleeding) includes perioperative intracranial bleeding within 48 h, bleeds that result in reoperation following closure of sternotomy for the purpose of controlling bleeding, bleeds that result in treatment with transfusion of ≥5 U of whole blood or packed red blood cells within a 48-h period; and chest tube output ≥2 liters within a 24-h period.

Type 5: fatal bleeding that directly results in death that is either clinically suspicious or is confirmed as the cause of death.

Bleeding [ Time Frame: 48 hrs ]
Bleeding defined as Bleeding Academic Research Consortium (BARC) ≥3 within 48 hours post study drug initiation or at hospital discharge, whichever occurs first, as adjudicated by the CEC

  • Participants With Myocardial Infarction (MI), Stroke/Transient Ischemic Attack (TIA), Unplanned Repeat Revascularization (URV), Death, and Minor Bleeding Up to 48 h Post Study Drug Administration [ Time Frame: Study drug administration (Day 1) up to 48 h post study drug initiation or at hospital discharge, whichever occurs first ]

    Outcome assessments at 48 h post study drug initiation include bleeding events defined as BARC Type 2 or greater (BARC ≥2), bleeding events defined as thrombolysis in myocardial infarction (TIMI) major and TIMI minor, and net adverse clinical events (NACE) as adjudicated by the CEC (NACE=death, MI, stroke/TIA, amputations, URV, or bleeding events defined as BARC ≥3).

    In addition to Type 3(a-c), 4, and 5, BARC ≥2 also includes Type 2 bleeding, which is any overt, actionable sign of hemorrhage (more bleeding than would be expected for a clinical circumstance, including bleeding found by imaging alone) that does not fit the criteria for Type 3, 4, or 5, but does meet at least one of the following criteria of: requiring nonsurgical, medical intervention by a health-care professional; leading to hospitalization or increased level of care; prompting evaluation.

  • Participants With MI, Stroke/TIA, URV, Death, or Minor Bleeding Up to Day 30 [ Time Frame: Study drug initiation (Day 1) up to 30 days ]

    Outcome assessments at Day 30 include NACE, Major Adverse Clinical Events (MACE=death, MI, stroke/TIA, amputation, or URV), and bleeding defined as BARC ≥2, as adjudicated by the CEC.

    In addition to Type 3(a-c), 4, and 5, BARC ≥2 also includes Type 2 bleeding, which is any overt, actionable sign of hemorrhage (more bleeding than would be expected for a clinical circumstance, including bleeding found by imaging alone) that does not fit the criteria for Type 3, 4, or 5, but does meet at least one of the following criteria of: requiring nonsurgical, medical intervention by a health-care professional; leading to hospitalization or increased level of care; prompting evaluation.

ENDOvascular Interventions With AngioMAX: The ENDOMAX Trial
ENDOvascular Interventions With AngioMAX: The ENDOMAX Trial
The primary objective of the study is to test whether anticoagulation with bivalirudin results in fewer major bleeding complications compared with unfractionated heparin (UFH) in participants undergoing peripheral endovascular interventions (PEI). The secondary objective is to test whether there were potential benefits from bivalirudin therapy on other clinically important events such as death, myocardial infarction (MI), stroke and/or transient ischemic attack (TIA), amputation, unplanned repeat revascularization (URV), and minor bleeding, as well as potential economic benefits that may result from improved clinical outcomes.

Interventional
Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
  • Peripheral Endovascular Interventions
  • Bleeding
  • Drug: Bivalirudin
    Bivalirudin is an anticoagulant that binds directly to thrombin in a bivalent and reversible fashion.
    Other Names:
    • AngioMAX
    • Angiox
  • Drug: Unfractionated Heparin
    Unfractionated heparin is an anticoagulant.
    Other Name: Heparin
  • Experimental: Bivalirudin
    Bivalirudin was administered as an intravenous (IV) bolus and infusion for the duration of the procedure (mean duration of 48.6 minutes). The bolus (0.75 milligrams (mg)/kilogram [kg]) was administered via systemic IV administration. Immediately after the bolus, an IV infusion of bivalirudin was initiated at a dose of 1.75 mg/kg/hour (h) (or 1 mg/kg/h for participants with an estimated glomerular filtration rate [eGFR] <30 milliliters/minute [mL/min]).
    Intervention: Drug: Bivalirudin
  • Active Comparator: Unfractionated Heparin
    UFH was administered as an IV bolus for the duration of the procedure (mean duration of 48.6 minutes). UFH was administered via weight-based IV bolus at a dose of 50 units (U)/kg to 70 U/kg. Additional bolus doses were administered per standard-of-care use.
    Intervention: Drug: Unfractionated Heparin
