Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
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)
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.
Study drug administration (Day 1) up to 48 h post study drug initiation or at hospital discharge, whichever occurs first
Secondary Outcomes (2)
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
Study drug administration (Day 1) up to 48 h post study drug initiation or at hospital discharge, whichever occurs first
Participants With MI, Stroke/TIA, URV, Death, or Minor Bleeding Up to Day 30
Study drug initiation (Day 1) up to 30 days
Study Arms (2)
Bivalirudin
EXPERIMENTALBivalirudin 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 \[mL/min\]).
Unfractionated Heparin
ACTIVE COMPARATORUFH 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.
Interventions
Bivalirudin is an anticoagulant that binds directly to thrombin in a bivalent and reversible fashion.
Unfractionated heparin is an anticoagulant.
Eligibility Criteria
You may qualify if:
- Participants ≥ 18 years of age
- Must be undergoing one of the following PEI procedures:
- Carotid artery stenting
- Lower Extremity Interventions (LEI) for Critical Limb Ischemia
- LEI for claudication
- Provide written informed consent prior to any study-specific procedure being performed
You may not qualify if:
- 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
- Weight less than 38 kg or more than 202 kg
- History of any bleeding diathesis or severe hematological disease

- Any surgery (excluding punch or shave skin biopsy) within the 30 days prior to randomization
- Concomitant percutaneous coronary intervention
- Any percutaneous coronary, endovascular, or structural heart disease procedure within 30 days prior to randomization
- International normalized ratio \>1.7 within 24 h prior to the index procedure
- Administration of therapeutic doses of UFH within 30 min prior to the index procedure (a low dose \[≤2000 U\] of heparin is permitted during the diagnostic angiogram prior to the intervention)
- Administration of enoxaparin within 8 h; other low molecular weight heparins or fondaparinux within 24 h; any oral anti-Xa or antithrombin agent within 48 h; or thrombolytics, glycoprotein inhibitors, or warfarin within 72 h prior to the index procedure
- Severe contrast allergy that cannot be pre-medicated
