In January 2005, the oversight responsibility of the Post-Approval Studies Program was transferred to the Division of Epidemiology (DEPI) of the Office of Surveillance and Biometrics (OSB)/Center for Devices and Radiological Health (CDRH).
The CDRH Post-Approval Studies Program encompasses design, tracking, oversight, and review responsibilities for studies mandated as a condition of approval of a premarket approval (PMA) application, protocol development product (PDP) application, or humanitarian device exemption (HDE) application. The program helps ensure that well-designed post-approval studies (PAS) are conducted effectively and efficiently and in the least burdensome manner.
CDRH has established an automated, internal tracking system that efficiently identifies the reporting status of active PAS studies ordered since January 1, 2005 based on study timelines incorporated in study protocols and agreed upon by the CDRH and applicants. This system represents CDRH's effort to ensure that all PAS commitments are fulfilled in a timely manner.
In addition, CDRH launched this publicly available webpage to keep all stakeholders informed of the progress of each PAS. The webpage displays general information regarding each PAS, as well as the overall study status (based on protocol-driven timelines and the adequacy of the data) and the applicant's reporting status for each submission due.
This is a single-arm, non-randomized, prospective, multi-center international study in subjects (>=22 years of age)
with TransAtlantic Inter-Society Consensus A, B and C lesion(s) in the infra-inguinal segment (SFA and/or Popliteal arteries). Subjects will be treated with PTA followed by the LifeStent Self-Expanding Stent System (FlexStar / FlexStar XL). The primary objectives of this investigation are to provide confirmatory evidence of safety and effectiveness of the LifeStent Self-Expanding Stent System in patients with de novo and restenotic (non-stented) lesion(s) in the infra-inguinal segment (SFA and/or Popliteal arteries). A secondary objective of this investigation is to continue to evaluate the clinical utility of the LifeStent Self-Expanding Stent System.
Study Population Description
This device is indicated for improvement of luminal diameter in the treatment of symptomatic de-novo
or restenotic lesions up to 160 mm in length in the native superficial femoral artery and proximal popliteal artery with reference vessel diameters ranging from 4.0 - 6.5 mm.
170 patients, 20 sites
The primary safety endpoint is freedom from death at 12-months post-procedure. The primary effectiveness is
freedom from procedural device malfunction.
Followup Visits and Length of Followup
Subjects will undergo a clinical evaluation at baseline (prior to study procedure), prior to hospital
discharge, 30 days post-procedure, 12, 24 and 36 months post-procedure.
