The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Sample Size The trial will enroll a minimum of 1,200 subjects (336 symptomatic and 864 asymptomatic subjects) at up to 350 sites in the United Sates.

The overall trial sample size was determined based on the secondary endpoint of peri- procedural DS by symptomatic status and its comparison with the respective PG (Symptomatic subjects: n= 336, accounting for 22 subject lost to follow-up; Asymptomatic subjects: n= 864 subjects, accounting for 58 subject lost to follow-up).

Data Collection Primary Endpoint: A composite rate of peri-procedural (within 30 days of the procedure) DS, plus ipsilateral stroke between day 31 and 1 year (365 days)

Secondary Endpoints

1. Composite of peri-procedural DS by symptomatic status

2. Ipsilateral stroke at 2 years

3. Composite of peri-procedural DS plus ipsilateral stroke at 1 and 2 years for octogenarians

4. Annual rate of clinically driven target lesion revascularization (TLR) through 2 years

Follow-up Visits and Length of Follow-up 2 years

Follow-up for all subjects will be performed at 24 hours post-procedure, 30 days, 1 year, and annually for a total of 2 years.
