Carotid Stenting vs. Surgery of Severe Carotid Artery Disease and Stroke Prevention in Asymptomatic Patients (ACT I)
Carotid Angioplasty and Stenting Versus Endarterectomy in Asymptomatic Subjects Who Are at Standard Risk for Carotid Endarterectomy With Significant Extracranial Carotid Stenotic Disease (ACT I)

The study is being conducted to demonstrate the non-inferiority of carotid artery stenting (CAS) using the Emboshield® Embolic Protection System with the Xact® Carotid Stent System to carotid endarterectomy (CEA) for the treatment of asymptomatic extracranial carotid atherosclerotic disease.

Randomization for ACT 1 employs a 3:1 ratio of CAS versus CEA. A lead-in phase of up to 400 carotid stent subjects will provide investigators experience with the study devices prior to pivotal enrollment.

Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
  • Carotid Artery Disease
  • Carotid Stenosis
  • Stroke
  • Atherosclerosis
  • Device: Carotid artery stenting with filter (interventional)
    Carotid artery stenting with filter (interventional)
  • Procedure: Carotid artery endarterectomy (surgical)
    Carotid artery endarterectomy (surgical)
  • Active Comparator: 1

    CAS group: 3:1 ratio of Carotid Artery Stenting (CAS) versus Carotid Endarterectomy (CEA).

    Subjects will be followed at 30 days, six (6), and 12 months post-procedure, and annually for four (4) additional years.

    Intervention: Device: Carotid artery stenting with filter (interventional)
  • Active Comparator: 2
