ACT 1 investigational trial for patients with asymtomatic carotid stenosis

The purpose of the ACT 1 investigational trial is to evaluate a potential treatment option for asymptomatic patients with carotid stenosis. The primary goal of the study is to compare carotid artery stenting (CAS) using the Emboshield Cerebral Protection System with the Xact RX Carotid Stent System to carotid endarterectomy (CEA). Patients must be asymptomatic with atherosclerotic extracranial internal carotid stenosis (ICA) with or without involvement of the contiguous common carotid artery (CCA).

You may be eligible for this study if you:

• Are between 18 and 80 years of age
• Are asymptomatic
• Have atherosclerotic extracranial internal carotid stenosis (ICA) with or without involvement of the contiguous common carotid artery (CCA)

You are not eligible for this study if you:

• Are symptomatic
• Have had a stroke or exhibited TIA within 180 days prior to randomization
• Have a known cardiac source of embolization
• Have had a myocardial infarction (MI) within previous 30 days
• Have GI bleeding
