ENDOvascular Interventions With AngioMAX: The ENDOMAX Trial
ENDOvascular Interventions With AngioMAX: The ENDOMAX Trial
The primary objective of the study is to demonstrate that anticoagulation with bivalirudin results in fewer major bleeding complications compared with unfractionated heparin (UFH) in subjects undergoing peripheral endovascular interventions (PEI). The secondary objective is to identify 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.

Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Peripheral Endovascular Interventions
Drug: Bivalirudin
  • Experimental: Bivalirudin
    Bivalirudin will be administered as a bolus and infusion. The bolus (0.75 mg/kg) will be administered via systemic IV administration. Immediately after the bolus, an IV infusion of bivalirudin will be initiated at a dose of 1.75 mg/kg/h (or 1 mg/kg/h for subjects with an eGFR <30 mL/min).
    Intervention: Drug: Bivalirudin
  • Active Comparator: Heparin
    UFH will be administered as an initial weight-based IV bolus at a dose of 50 units (U)/kg to 70 U/kg. Additional bolus doses may be administered per the pre-defined heparin dosing algorithm.
    Intervention: Drug: Bivalirudin

Exclusion Criteria:

  • Any known contra-indication to the use of bivalirudin or UFH
  • Acute limb ischemia
  • Planned amputation regardless of the outcome of the PEI
  • Dialysis dependent

  • Administration of therapeutic doses of UFH within 30 minutes (min) prior to the index procedure (a low dose [≤2000 units (U)] of heparin is permitted during the diagnostic angiogram prior to the intervention)
  • Administration of enoxaparin within 8 hours; other low molecular weight heparins (LMWHs) or fondaparinux within 24 hours; any oral anti-Xa or antithrombin agent within 48 hours; or thrombolytics, glycoprotein inhibitors (GPI), or warfarin within 72 hours prior to the index procedure
  • Severe contrast allergy that cannot be pre-medicated
  • Procedures performed by radial access when they are intended as the primary access site for the index procedure
  • Known or suspected pregnant women or nursing mothers
  • Previous enrollment in this study (MDCO-BIV-12-03)
  • Participation in other investigational drug or device trials within 30 days prior to randomization
  • Subjects who, for any reason, are deemed by the investigator to be inappropriate for this study
