PRIZER, a new study investigating dual layer technology in patients with FemPop lesions

8/3/2020 - LEUVEN, BELGIUM

Terumo Europe N.V., a leading medical device company, announces the initiation of a new Post-market study: the Prospective, Multicenter, Post-market, Single aRm study, to confIrm the performance of the RenZanTM Peripheral Stent System in treating subjects with SupErficial Femoral and/or Popliteal aRtery disease (PRIZER). 

Peripheral arterial disease (PAD) is a progressive disorder caused by atherosclerotic changes in the blood vessel wall, which result in stenosis or occlusion of the arteries outside the heart and brain1. The pathology affects >200 million people worldwide2,3. During the preceding decade alone the number of PAD-affected individuals increased by 13% in high- and by 29% in low-income countries3. The PAD prevalence increases with age, affecting >20% of octogenarians (>80-year-old individuals)1-3. Lower extremity PAD is its most common subset1. PAD is associated with high morbidity and both cardiovascular and all-cause mortality rates. The pathology causes major personal, medical and socio-economic burden, increasingly becoming a global healthcare concern1-4.

The RenzanTM Peripheral Stent System consists of a self-expanding nitinol stent pre-mounted on the distal portion of a rapid exchange (RX) delivery catheter, constructed from 2 layers of tubular braided nitinol wire mesh.

The study plans to enrol 135 patients, in approximately 10 European centers in 5 countries. Patients will be stratified in 2 groups: 90 FEM-POP patients and 45 Isolated POP patients.   

The PRIZER Study aims to confirm the safety and efficacy of the RenzanTM Peripheral Stent System in treating subjects with superficial femoral (SFA) and/or popliteal (POP) artery disease and to assess of the primary patency of the artery evaluated at 12 months, compared to clinical results coming from other clinical trials using similar metallic scaffolds.

"My enthusiasm about the dual layer RoadsaverTM stent in the carotid field can be investigated in this way in the even more challenging infra-inguinal area", commented Dr. Koen Deloose, Head of Department of Vascular Surgery at AZ Sint Blasius Dendermonde hospital in Belgium, Principal investigator of PRIZER study. "In current times where drug eluting technology is only reserved for high risk patients and where the need for scaffolding post DCB treatment is high, a lot of interventionalists are really looking for a 'daily practice' modern scaffold that is extremely flexible, well balanced in COF and radial resistive force and easy to implant accurately. The new 018"-compatible nitinol braided RenzanTM stent with dual layer technology over the full length showed in some proof of concept cases to respond extremely well to all my expectations. The PRIZER study offers us the possibility to further investigate the safety and efficacy of the RenzanTM Peripheral Stent System for treatment of superficial femoral (SFA) and/or popliteal (POP) artery disease in 135 patients", Dr. Deloose continued.


"We are very proud to contribute to our commitment to physicians and their patients and drive innovation in the field of peripheral artery disease", said Jim Rushworth, Chief Commercial Officer, TIS Global. "With this clinical trial, we explore initiatives to increase our footprint in peripheral interventions."

"This new technology ensures a great flexibility, conformability to the vessel and fracture resistance", commented Dr. Christophe Giot, Chief Medical Officer, Terumo Europe. "The PRIZER study aims to provide scientific evidence for RENZAN stent in patients suffering from Peripheral arterial disease. "
