Information provided by: Abbott Vascular
ClinicalTrials.gov Identifier: NCT00106938
  Purpose

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


Condition Intervention Phase

Carotid Stenosis
Stroke
Atherosclerosis
Device: Carotid artery stenting with filter (interventional)
Procedure: Carotid artery endarterectomy (surgical)
Phase III

Study Type: Interventional
Study Design: Randomized, Open Label, Active Control, Parallel Assignment, Safety/Efficacy Study
Official Title: 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)

Primary Outcome Measures:
  • Occurrence of major adverse events 30 days following the procedure [ Time Frame: Acute to 30 days ] [ Designated as safety issue: Yes ]
  • Occurrence of ipsilateral strokes between 31 and 365 days post procedure [ Time Frame: 31 through 365 days post procedure ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Acute device success [ Time Frame: Acute ] [ Designated as safety issue: Yes ]
  • Procedural success [ Time Frame: Acute ] [ Designated as safety issue: No ]
  • Composite morbidity at 0 - 30 days Post-Procedure [ Time Frame: 0 to 30 days post procedure ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
1: Active Comparator

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

A lead-in phase of up to 400 carotid stent subjects will provide investigators experience with the study devices prior to pivotal enrollment.

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

2: Active Comparator

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

A lead-in phase of up to 400 carotid stent subjects will provide investigators experience with the study devices prior to pivotal enrollment.

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

Procedure: Carotid artery endarterectomy (surgical)
Carotid artery endarterectomy (surgical)

Detailed Description:

Patients will be randomized to either an interventional treatment using a carotid artery stent and filter or the surgical procedure of carotid endarterectomy, on a 3:1 basis. This means that three interventional procedures will be conducted to each surgical (CEA) one, on average, for every four patients.
