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) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

OSB Lead-PAS 1 (Extended Follow-up Study)


Suggest Enhancement / Report Issue | export reports to excelExport to Excel
General
Study Status Progress Adequate
Application Number P130024 / PAS001
Date Current Protocol Accepted 10/09/2014
Study Name OSB Lead-PAS 1 (Extended Follow-up Study)
General Study Protocol Parameters
Study Design Prospective Cohort Study
Data Source Sponsor Registry
Comparison Group Historical Control
Analysis Type Analytical
Study Population Transit. Adolescent B (as adults) : 18-21 yrs, Adult: >21
Detailed Study Protocol Parameters
Study Design Description Prospective cohort study, continued follow-up of premarket cohorts and LEVANT 2 Safety Registry subjects
Study Population Description Patients treated with the Lutonix DCB for stenosis of the femoropopliteal artery
Sample Size 657 DCB subjects from the LEVANT 2 Safety Registry

372 DCB subjects from the LEVANT 2 Pivotal IDE study

160 PTA controls from the LEVANT 2 Pivotal IDE study

The assumption is that results at 2 years will be proportionally similar in DCB subjects and controls to what

they were in the pivotal IDE study. The PAS study will have a much larger sample size and therefor greater power than that of the pivotal IDE study.
Data Collection Primary effectiveness: Primary patency of the target lesion

at 24 months

Primary safety: Composite freedom for all cause

perioperative (within 30 days), index limb amputation (2

years), index limb re-intervention (2 years), and index limbrelated death (2 years)

Secondary endpoints: Individual components of the primary

safety endpoint, device- and drug-related adverse events,

all-cause death, major vascular complications, target lesion

revascularization, and Rutherford classification
Follow-up Visits and Length of Follow-up 5 years Clinical follow-up, including Duplex Ultrasound (DUS) will be

done at 6 months, 12 months, and 24 months. Telephone

f/u will be done at 1 month, 3, 4, and 5 years.
