Primary Effectiveness Endpoint
The primary effectiveness endpoint assesses primary patency at 12 months
post-procedure. This effectiveness endpoint is designed to demonstrate that the
12-month primary patency for the ELUVIA treatment group is superior to the
Self-Expanding Bare Nitinol Stents treatment group.
Primary vessel patency is defined as a binary endpoint and will be determined
to be a success when the duplex ultrasound (DUS) Peak Systolic Velocity Ratio
(PSVR) is <= 2.4 at the 12-month follow-up visit in the absence of
clinically-driven TLR or bypass of the target lesion. All DUS readings will be
assessed by an independent core laboratory

Background summary
The ELUVIA stent system is intended to improve the luminal diameter in the
treatment of symptomatic de novo or restenotic lesions in the native SFA
(superficial femoral artery) and/or PPA (proximal popliteal artery).
The ELUVIA stent is a paclitaxel eluting, self-expanding nitinol stent
developed on the same stent and delivery system as the BSC Innova* Vascular
Self-Expanding Stent System.
The theoretical basis for improved performance with the use of nitinol stents
is due to the unique properties of nitinol such as flexibility, persistent
radial force when oversized to a vessel, and ability for crush recovery in
these high flexion and torsion force areas in the femoropopliteal arteries. In
addition, self-expanding nitinol stents are not as prone to external
compression as are balloon-expandable stents. Moreover, due to its smaller
arterial diameter and complex nature, the femoropopliteal segment does not
respond well to rigid stents. As such, the most flexible nitinol stent is
needed to mitigate stent fracture that often occurs in the femoropopliteal
arteries.
To supress neointimal growth and to prevent restenosis after stent deployment,
the ELUVIA stent is coated with a pharmaceutical, Paclitaxel.
Studies have shown that paclitaxel inhibits neointimal hyperplasia by
disrupting normal microtubule function, thereby inhibiting smooth muscle cell
migration, proliferation, and extracellular matrix secretion thus supporting
short-term local delivery of paclitaxel for inhibiting restenosis in the SFA.
Study objective
To confirm the superior effectiveness of the ELUVIA Drug-Eluting Vascular Stent
System (ELUVIA Stent) for treating Superficial Femoral Artery (SFA) and/or
Proximal Popliteal Artery (PPA) lesions up to 210 mm in length when compared
against bare metal stents, and collect additional data including health
economics data.
Study design
A prospective, multi-center study confirming the superior effectiveness of the
ELUVIA stent versus Self-Expanding Bare Nitinol Stents in the treatment of
lesions 30-210 mm long located in the femoropopliteal arteries in subjects with
symptoms classified as Rutherford categories 2-4.
The study is a 2:1 randomized (ELUVIA vs Self-Expanding Bare Nitinol Stents),
controlled, single-blind, superiority trial (RCT). Randomization will be
stratified to ensure equal distribution of ELUVIA and Self-Expanding Bare
Nitinol Stents in different lesion length subsets.
Intervention
test device:
The ELUVIA Stent is a paclitaxel-eluting, self-expanding nitinol stent
developed on the same stent and delivery system as the BSC Innova* Vascular
Self-Expanding Stent System.
control device:
Commercially available stents in Europe. Permitted stents are Supera (Abbott),
Lifestent (CR Bard), Everflex (Covidien/Medtronic), S.M.A.R.T. Flex
(Cordis/Cardinal), S.M.A.R.T. Control (Cordis/Cardinal), Pulsar (Biotronik),
COMPLETE SE (Medtronic), Misago (Terumo) or Innova (Boston Scientific)
indicated for improving luminal diameter for the treatment of de novo or
restenotic symptomatic lesions in native vascular disease of the above-the-knee
femoropopliteal arteries.
Study burden and risks
The study will not expose the study subjects to any adjunct invasive or
stressful examination as compared to if the subject was treated outside the
study according to standard practice. both the 'testdevice' and 'control devie'
are CE-marked (commercially available) and are considered standard of care
treatment.
